Detailed Description
Embodiments of the present invention will be described with reference to the accompanying drawings as appropriate. First, a rotary tool (rotary tool) F for joining used in the joining method according to the embodiment of the present invention will be described. The main joining rotary tool F is a tool for friction stir joining. As shown in fig. 1, the main joining rotary tool F is made of, for example, tool steel, and mainly includes a base shaft portion F1, a base end side pin F2, and a tip side pin F3. The base shaft portion F1 has a cylindrical shape and is connected to the main shaft of the friction stir apparatus.
The base-end-side pin F2 is continuous with the base shaft portion F1 and tapers toward the leading end. The base-end-side pin F2 has a truncated cone shape. The taper angle a of the base end side pin F2 may be set as appropriate, and is, for example, 135 ° to 160 °. If the taper angle a is smaller than 135 ° or larger than 160 °, the joining surface roughness after friction stirring becomes large. The taper angle a is larger than a taper angle B of a tip side pin F3 described later. As shown in fig. 2, a stepped pin step F21 is formed on the outer peripheral surface of the base end side pin F2 over the entire height direction. The pin step F21 is formed in a spiral shape so as to be wound to the right or left. That is, the pin step portion F21 has a spiral shape in plan view and a stepped shape in side view. In the present embodiment, since the main joining rotary tool F is rotated to the right, the pin step portion F21 is set to go around from the base end side to the tip end side to the left.
Further, it is preferable that the pin level difference portion F21 is set to go around from the base end side to the tip end side to the right when the main joining rotary tool F is rotated to the left. Thereby, the plastic fluidizing material is guided to the leading end side by the pin level difference portion F21, and therefore, the metal overflowing to the outside of the joined metal members can be reduced. The pin step F21 is composed of a step bottom F21a and a step side F21 b. The distance X1 (horizontal distance) between the apexes F21C and F21C of the adjacent pin step portions F21 is appropriately set in accordance with a step angle C and a height Y1 of the step side surface F21b, which will be described later.
The height Y1 of the step side surface F21b may be appropriately set, for example, 0.1 to 0.4 mm. If the height Y1 is less than 0.1mm, the bond front roughness increases. On the other hand, if the height Y1 is greater than 0.4mm, the joining surface roughness tends to increase, and the number of effective level differences (the number of pin level differences F21 that contact the joined metal members) also decreases.
The step angle C between the step bottom surface F21a and the step side surface F21b may be appropriately set, but is set to 85 ° to 120 °, for example. The step bottom surface F21a is parallel to the horizontal plane in the present embodiment. The step bottom surface F21a may be inclined in the range of-5 ° to 15 ° with respect to the horizontal plane from the rotation axis of the tool toward the outer circumferential direction (negative below the horizontal plane and positive above the horizontal plane). The distance X1, the height Y1 of the step side face F21b, the step angle C, and the angle of the step bottom face F21a with respect to the horizontal plane are appropriately set so that the plastic fluidizing material is discharged to the outside without being accumulated and adhered to the inside of the pin step portion F21 at the time of friction stirring, and the plastic fluidizing material can be pressed by the step bottom face F21a to reduce the joining surface roughness.
As shown in fig. 1, the front-end side pin F3 is formed continuously with the base-end side pin F2. The front end side pin F3 has a truncated cone shape. The front end of the front end side pin F3 is a flat surface F4. The flat face F4 is perpendicular to the axis of rotation of the tool. The taper angle B of the tip side pin F3 is smaller than the taper angle a of the base side pin F2. As shown in fig. 2, a spiral groove F31 is formed in the outer peripheral surface of the distal end side pin F3. The spiral groove F31 may be rounded to the right or left, but in the present embodiment, the main joining rotary tool F is engraved so as to be rounded to the left from the base end side to the tip end side, because it is rotated to the right.
Further, when the main joining rotary tool F is rotated to the left, the spiral groove F31 is preferably set to go around from the base end side to the tip end side to the right. Thereby, the plastic fluidizing material is guided toward the leading end side by the spiral groove F31, and therefore, the metal overflowing to the outside of the joined metal members can be reduced. The spiral groove F31 is formed by a spiral bottom surface F31a and a spiral side surface F31 b. The distance (horizontal distance) between the apexes F31c, F31c of the adjacent spiral grooves F31 is set to a length X2. The height of the spiral side surface F31b was set to a height Y2. The helix angle D formed by the helix bottom face F31a and the helix side face F31b is, for example, 45 ° to 90 °. The spiral groove F31 raises frictional heat by contacting with the joined metal members, and includes a function of guiding the plastic fluidizing material toward the leading end side.
The primary engagement rotary tool F can be appropriately changed in design.
Fig. 3 is a side view showing a first modification of the main joining rotary tool of the present invention. As shown in fig. 3, in the primary joining rotary tool FA according to the first modification, the step angle C formed by the step bottom surface F21a and the step side surface F21b of the pin step portion F21 is 85 °. The level difference floor F21a is parallel to the horizontal plane. In this way, the level difference bottom surface F21a may be parallel to the horizontal plane, and the level difference angle C may be set to an acute angle within a range in which the plastic fluidizing material is discharged to the outside without being accumulated and adhered to the pin level difference portion F21 during friction stirring.
Fig. 4 is a side view showing a second modification of the main joining rotary tool of the present invention. As shown in fig. 4, in the primary joining rotary tool FB according to the second modification, the step angle C of the pin step F21 is 115 °. The level difference floor F21a is parallel to the horizontal plane. In this way, the step bottom surface F21a may be parallel to the horizontal plane, and the step angle C may be an obtuse angle in a range functioning as the pin step portion F21.
Fig. 5 is a side view showing a third modification of the main joining rotary tool of the present invention. As shown in fig. 5, in the main joining rotary tool FC according to the third modification, the step bottom surface F21a is inclined upward by 10 ° with respect to the horizontal surface in the outer circumferential direction from the rotational axis of the tool. The level difference side F21b is parallel to the plumb line. In this way, the step bottom surface F21a may be formed to be inclined upward from the horizontal plane toward the outer circumferential direction from the rotation axis of the tool within a range in which the plastic fluidized material can be pressed during friction stirring. The effects equivalent to those of the following embodiments can be obtained by the first to third modifications of the main joining rotary tool.
[ first embodiment ]
Next, the heat transfer plate 1 of the first embodiment will be described. The "front surface" in the following description means a surface opposite to the "back surface". As shown in fig. 6, the heat transfer plate 1 of the present embodiment is mainly composed of a base member 2 and a cover plate 5. The base member 2 is substantially rectangular parallelepiped. The base member 2 is formed with a groove 3 and a lid groove 4. The material of the base member 2 and the cover plate 5 is not particularly limited as long as friction stirring is possible, but in the present embodiment, it is an aluminum alloy.
The groove 3 communicates from one side face to the other side face at the center of the base member 2. The groove 3 is concavely arranged on the bottom surface of the cover groove 4. The bottom of the groove 3 is arc-shaped. The opening of the recess 3 is open to the front face 2a side of the base member 2.
The cover groove 4 has a width larger than that of the recess groove 3 and is formed continuously with the recess groove 3 on the front surface 2a side of the recess groove 3. The cover groove 4 is rectangular in cross-sectional view and is open to the front surface 2a side.
The cover 5 is a plate-like member inserted into the cover groove 4. The base member 2 and the lid plate 5 are integrated by friction stir bonding. A space surrounded by the groove 3 of the heat transfer plate 1 and the lower surface of the cover plate 5 serves as a flow path through which a fluid flows.
Next, a method of manufacturing a heat transfer plate according to a first embodiment will be described. In a method for manufacturing a heat transfer plate, a preparation step, a cover plate insertion step, a temporary bonding step, and a main bonding step are performed.
As shown in fig. 7A and 7B, the preparation step is a step of preparing the base member 2 and the cover 5. The base member 2 may be formed with the concave groove 3 and the lid groove 4 by cutting using an end mill or the like, or the base member 2 may be formed with the concave groove 3 and the lid groove 4 in advance by molding, extrusion, or the like. The cover plate 5 can be formed, for example, by extrusion molding.
As shown in fig. 7B, the cover plate insertion step is a step of inserting the cover plate 5 into the cover groove 4. A pair of side walls of the lid groove 4 abut a pair of side surfaces of the lid plate 5 to form abutting portions J1, J2. A fine gap is formed in the butting portions J1 and J2. Hereinafter, even when a fine gap is formed between the two abutting surfaces like the abutting portions J1 and J2, the abutting portions are also referred to as "abutting portions". The width of the gap may be appropriately set, and is, for example, about 0.1mm to 1.0 mm. The front face 5a of the cover plate 5 is coplanar with the front face 2a of the base member 2. The front surface 2a of the base member 2 is referred to as " front surface 2a 1" on one side in the width direction and " front surface 2a 2" on the other side, as needed.
As shown in fig. 8 and 9, the temporary joining step is a step of performing friction stir welding on the butted portions J1 and J2 in advance by using the temporary joining rotating tool FD. The temporary joining rotary tool FD has the same configuration as the main joining rotary tool F, and includes a base shaft portion F1D, a base end side pin F2D, and a tip side pin F3D. The temporary engagement rotary tool FD is smaller than the main engagement rotary tool F.
In the temporary joining step, the friction stir welding of the butt J1 is performed with the start position set at one side in the extending direction of the butt J1 and the end position set at the other side in the extending direction. In the temporary joining step, friction stir joining is performed with the outer peripheral surface of the base end side pin F2D in contact with the front surface 2a of the base member 2 and the front surface 5a of the lid plate 5. A plasticized region W1 is formed on the movement locus of the temporary joining rotating tool FD. The abutting portion J2 is also temporarily engaged in the same manner.
The temporary joining may be performed continuously or intermittently to the abutting portions J1 and J2. Further, the temporary joining rotating tool FD may be moved at the start position and gradually pressed in. Further, it is also possible to move the temporary engagement rotary tool FD at the end position and gradually draw it out. The starting position and the ending position of the temporary bonding step may be set on the front surface 2a of the base member 2.
The primary joining step is a step of friction stir joining the butting portions J1, J2 using the primary joining rotary tool F. As shown in fig. 9, in the primary joining step, friction stirring was continuously performed in three sections, i.e., a press-in section from the start position SP1 to the intermediate point S1 on the butt J1, a main section from the intermediate point S1 to the intermediate point S2, and a disengagement section from the intermediate point S2 to the end position EP 1. The start position SP1 is set at a position away from the butting portion J1 in the front face 2a1 of the base member 2. In the present embodiment, the angle formed by the butt portion J1 and the line segment connecting the start position SP1 and the intermediate point S1 is set to be an obtuse angle.
In the press-fitting section in the main joining step, as shown in fig. 10, friction stirring is performed from the start position SP1 to the intermediate point S1. In the press-fitting section, the front pin F3 rotating to the right is inserted to the start position SP1, and the front pin F3 is moved to the intermediate point S1. At this time, as shown in fig. 10, the distal end side pin F3 is gradually pushed in so as to reach a predetermined "predetermined depth" at least before reaching the intermediate point S1. That is, the main joining rotary tool F is not stopped at one place, but is moved on the butting portion J1 and gradually lowered.
After reaching intermediate point S1, the friction stir welding is immediately shifted to the main zone. As shown in fig. 10 and 11, in the main zone, the main joining rotary tool F is moved so that the rotation center axis of the tip-side pin F3 coincides with the butting portion J1. The "predetermined depth" is an insertion depth of the distal end side pin F3 in the main section of the butt J1. In the main section, the "predetermined depth" of the front-end pin F3 is set so that the flat surface F4 of the front-end pin F3 reaches the bottom surface 4a of the lid groove 4. The "predetermined depth" of the distal-side pin F3 may be set as appropriate, and may be set so that the distal-side pin F3 does not reach the stepped bottom surface 4a, for example.
As shown in fig. 9 and 12, the main engagement rotary tool F immediately shifts to the disengagement section after reaching the intermediate point S2. In the disengagement section, as shown in fig. 12, the front-end-side pin F3 is gradually moved upward from the intermediate point S2 to the end position EP1, and the front-end-side pin F3 is disengaged from the base member 2 at the end position EP 1. That is, the main joining rotary tool F is moved to the end position EP1 and gradually pulled out (raised) without being stopped at one place. The end position EP1 of the present embodiment is set at a position where an angle formed by a line segment connecting the end position EP1 and the intermediate point S2 and the butt portion J1 is an obtuse angle. The plasticized region W1 is formed on the movement locus of the primary joining rotary tool F.
In the main joining step, start position SP2, end position SP2, and intermediate points S1 and S2 are also set for butting portion J2, and friction stir joining is performed in the same manner as butting portion J1.
According to the method for manufacturing a heat transfer plate of the present embodiment described above, in the insertion section of the main joining step, the main joining rotary tool F is moved from the start positions SP1, SP2 to the positions overlapping the butting portions J1, J2, and the tip-side pin F3 is gradually pushed in to a predetermined depth, whereby the frictional heat at the butting portions J1, J2 can be prevented from becoming excessively large.
Similarly, in the disengagement section of the primary engagement process, the primary engagement rotary tool F is moved from the position overlapping the butting portions J1, J2 to the end positions EP1, EP2, and the distal-side pin F3 is gradually raised from a predetermined depth to be disengaged, thereby preventing the frictional heat at the butting portions J1, J2 from becoming excessively large. Thus, by preventing the frictional heat at the butting portions J1 and J2 from becoming excessive, a poor joint at the butting portions J1 and J2 can be prevented.
In addition, in the conventional method for manufacturing a heat transfer plate, a socket is separately provided at an end portion of the base member, and a start position and an end position of the rotary tool are set in the socket. However, according to the present embodiment, since the socket is not required, the number of parts can be reduced, and the number of man-hours can be reduced.
In the main joining step of the present embodiment, since friction stirring is performed in a state where the outer peripheral surface of the base-end-side pin F2 is in contact with the front surface 2a of the base member 2 and the front surface 5a of the lid plate 5, the occurrence of burrs can be reduced. Further, the plastic fluidizing material can be pressed by the outer periphery of the base end side pin F2, and therefore, the level difference groove formed in the joining surface (the front surface 2a of the base member 2 and the front surface 5a of the lid plate 5) can be reduced, and the ridge portion formed in the vicinity of the level difference groove can be eliminated or reduced. Further, since the stepped pin level difference portion F21 of the base end side pin F2 is shallow and has a large outlet, the plastic fluidizing material is easily discharged to the outside of the pin level difference portion F21 while being pressed by the level difference bottom surface F21 a. Therefore, even if the plastic fluidizing material is pressed by the base end side pin F2, the plastic fluidizing material is less likely to adhere to the outer peripheral surface of the base end side pin F2. This reduces the surface roughness of the joint and desirably stabilizes the joint quality.
In the main joining step, the front surface 2a of the base member 2 and the front surface 5a of the lid plate 5 are pressed by the outer periphery of the base end side pin F2 and friction stir welded, so that the plastic fluidizing material can be pressed and filled into the gap between the butting portions J1 and J2 while preventing the metal shortage in the joined portion. In other words, even when a gap is provided in the butting portions J1, J2 as in the primary joining process, the plastic fluidizing material can be reliably filled in the butting portions J1, J2. Thus, even if the molding accuracy of the lid groove 4 and the lid plate 5 of the base member 2 is not high, the joining can be performed satisfactorily.
In the main joining step, the flat surface F4 of the front end side pin F3 is set to reach the bottom surface 4a of the lid groove 4, whereby the joining strength between the base member 2 and the lid plate 5 can be improved.
In addition, by performing the temporary joining step, positional deviation of the base member 2 and the lid plate 5 and cracking of the butting portions J1, J2 in the main joining step can be prevented. The temporary joining step may be performed by welding, or by using another rotary tool, and by performing friction stirring while the outer peripheral surface of the base end side pin FD2 of the temporary joining rotary tool FD is in contact with the front surface 2a of the base member 2 and the front surface 5a of the lid plate 5, the occurrence of burrs can be suppressed.
In the temporary joining step, the temporary joining rotating tool FD may be moved to a start position and gradually pushed in.
In the temporary joining step, the temporary joining rotation tool FD may be moved to the end position and gradually disengaged.
In the main joining step, the positions of the start positions SP1 and SP2 may be appropriately set, and the angles formed by the start positions SP1 and SP2 and the butting portions J1 and J2 are set to be obtuse angles, so that the main joining rotary tool F can be smoothly transferred to the main zone without decreasing the moving speed of the main joining rotary tool F at the intermediate points S1 and S2. This prevents excessive frictional heat from being generated by the stop of the main joining rotary tool F at the butting portions J1 and J2 or a decrease in the moving speed. In addition, by setting the end positions EP1 and EP2 in the same manner as the start positions SP1 and SP2, the main joining rotary tool F can be smoothly moved from the main zone to the escape zone.
In the primary joining step, the rotation speed of the primary joining rotary tool F may be constant or may be variable. In the press-fitting section in the main joining step, V1 > V2 may be set when the rotation speed of the main joining rotary tool F at the start position SP1 is V1 and the rotation speed of the main joining rotary tool F between the intermediate points S1 and S2 is V2. The rotation speed V2 is a predetermined constant rotation speed in the butting portion J1 and J2. That is, the rotational speed may be set to a high value in advance at the start positions SP1 and SP2, and the rotational speed may be gradually reduced in the push-in section to make the transition to the main section.
In the disengagement section of the main engagement process, when the rotation speed of the main engagement rotary tool F between the intermediate points S1 to S2 is V2 and the rotation speed of the main engagement rotary tool F at the time of disengagement at the end position EP1 is V3, V3 > V2 may be set. That is, after the transition to the disengagement section, the rotation speed may be gradually increased toward the end positions EP1 and EP2, and the primary engagement rotary tool F may be disengaged. When the main joining rotary tool F is pressed into or disengaged from the metal members to be joined, the rotational speed can be set as described above to compensate for the small pressing force in the press-in section or the disengagement section, and therefore, friction stirring can be performed desirably.
[ modified example of the first embodiment ]
Next, a method of manufacturing a heat transfer plate according to a modification of the first embodiment of the present invention will be described. As shown in fig. 13, the method of manufacturing a heat transfer plate according to the modification of the first embodiment differs from the first embodiment in that both the start position SP2 and the end position EP2 are set at the butting portion J2 during the friction stirring at the butting portion J2 in the main joining step. In the modification of the first embodiment, the description will be mainly focused on the differences from the first embodiment.
In the method of manufacturing a heat transfer plate according to the modification of the first embodiment, a preparation step, a mounting step, and a main joining step are performed. The preparation step and the mounting step are the same as those in the first embodiment.
Friction stirring of the butting portion J1 in the main joining step is performed in the same manner as in the first embodiment. In the modification of the first embodiment, in the friction stirring of the butting portion J2, as shown in fig. 13, the start position SP2 and the end position EP2 are set to the butting portion J2. In the main joining step, the friction stirring is continuously performed in three sections, i.e., an insertion section from the start position SP2 to the intermediate point S1, a main section from the intermediate point S1 to the intermediate point S2 on the butt portion J2, and a disengagement section from the intermediate point S2 to the end position EP2 so that the rotation center axis of the tip-side pin F3 overlaps the butt portion J2.
As shown in fig. 13, friction stirring is performed from the start position SP2 to the intermediate point S1 in the press-fit section. In the press-fitting section, the tip-side pin F3 that has rotated rightward is inserted to the start position SP2 on the butting portion J2, and the tip-side pin F3 is moved to the intermediate point S1. At this time, the distal pin F3 is gradually pushed in to reach a predetermined "predetermined depth" at least before reaching the intermediate point S1. That is, the main joining rotary tool F is moved on the butting portion J2 and gradually lowered without being stopped at one place. After reaching the intermediate point S1, the friction stir welding is shifted to the main zone, and the main welding rotating tool F is moved over the butting portion J2. The predetermined depth is the same as that of the first embodiment.
As shown in fig. 13, the main engagement rotary tool F immediately shifts to the disengagement section after reaching the intermediate point S2. In the escape section, the front end side pin F3 is gradually moved upward from a predetermined depth from the intermediate point S2 to the end position EP2 on the butt portion J2, and the front end side pin F3 is disengaged from the base member 2 at the end position EP 2. That is, the main joining rotary tool F is moved on the butting portion J2 and gradually pulled out without being stopped at one place.
According to the modification of the first embodiment described above, the effects substantially equal to those of the first embodiment can be obtained. Further, by moving the main joining rotary tool F to the butting portion J2 and gradually pushing the distal end side pin F3 in to a predetermined depth, it is possible to prevent the frictional heat from becoming excessively large at one point on the butting portion J2. Further, by moving the main joining rotary tool F on the butting portion J2 and gradually extracting the distal end side pin F3 from a predetermined depth, it is possible to prevent the frictional heat from becoming excessive at one point on the butting portion J2. Further, the plastic fluidizing material can be pressed by the outer periphery of the base end side pin F2, and therefore the generation of burrs can be suppressed.
Further, when the start position SP2 and the end position EP2 are set on the abutting portion J2 as in the modification of the first embodiment, the plasticized region W remaining on the front surface 2a2 can be made small. In the modification of the first embodiment, the start position SP1 and the end position EP1 may be set to the butting portion J1 even during friction stirring of the butting portion J1.
[ second embodiment ]
Next, a method of manufacturing a heat transfer plate according to a second embodiment of the present invention will be described. The heat transfer plate 1B of the present embodiment is different from the heat transfer plate 1 of the first embodiment in that it includes the heat medium tube 6. The heat medium pipe 6 is a member through which a fluid flows.
In the method of manufacturing a heat transfer plate according to the present embodiment, a preparation step, a heat medium pipe insertion step, a cover plate insertion step, a temporary bonding step, and a main bonding step are performed. The preparation process, the cover plate insertion process, the temporary bonding process, and the main bonding process of the present embodiment are the same as those of the first embodiment. The manufacturing method of the present embodiment is different from the first embodiment in that the heat medium pipe insertion step is performed. In the present embodiment, a description will be given mainly on a part different from the first embodiment.
As shown in fig. 14B, the heat medium pipe insertion step is a step of inserting the heat medium pipe 6 into the concave groove 3 of the base member 2 (see fig. 14A) prepared in the preparation step. The sizes and the like of the concave groove 3 and the heat medium pipe 6 may be set as appropriate, but in the present embodiment, the outer diameter of the heat medium pipe 6 is substantially the same as the width and the depth of the concave groove 3.
In the lid plate insertion step of the present embodiment, when the lid plate 5 is inserted into the lid groove 4, the recess 3, the lower surface of the lid plate 5, and the heat medium pipe 6 form a void Q as shown in fig. 14B. When the void portion Q is formed as described above, the void portion Q may be filled in by the main bonding step as shown in fig. 15. By narrowing the widths of the lid groove 4 and the lid plate 5, the positions of the butting portions J1, J2 are brought close to the heat medium pipe 6 and the void portion Q, and the plastic fluidizing material formed by the main joining rotating tool F can be made to flow into the void portion Q in the main joining process. At this time, the outer periphery of the base end side pin F2 presses the front surfaces 2a1 and 2a2 of the base member 2 and the front surface 5a of the lid plate 5 to perform friction stirring, so that the plastic fluidizing material can be reliably pressed into and filled in the gap Q. By causing the plastic fluidizing material to flow into the gap portion Q, the periphery of the pipe 6 for heat medium is filled with the metal, and therefore, the water tightness and the air tightness of the heat transfer plate 1B can be further improved.
According to the method of manufacturing a heat transfer plate of the present embodiment, substantially the same effects as those of the first embodiment can be obtained. Further, the heat transfer plate 1B including the heat medium tube 6 can be easily manufactured.
Further, for example, the shapes of the concave groove 3, the lid groove 4, the lid plate 5, and the heat medium pipe 6 of the first and second embodiments are merely examples, and may be other shapes.
