Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
Fig. 8 shows a front view structure of the tool line, fig. 9 shows a top view structure of the tool line, and fig. 10 shows a three-dimensional structure of the tool line. As shown in fig. 8-10, the tooling line mainly includes a lifting device, a lifting mechanism 1, a column assembly 6 vertically arranged on the ground, and a carrier bar 7 vertically connected to one end of the fixed column assembly 6 far from the ground. The upright post assembly 6 and the bearing beam 7 integrally form a cantilever beam structure. The other end of the carrier beam 7 is positioned above the roll forming machine, and the lifting appliance mechanism 1 drives the lifting appliance to move along the length direction of the carrier beam 7.
Fig. 6 shows that the free end of the machine spindle is in a stepped shaft shape, as shown in fig. 6, the machine spindle sequentially includes a machine spindle main body 101, a machine tool withdrawal groove, and a machine spindle boss stage 102 from inside to outside, and the diameter of the machine spindle boss stage 102 is smaller than that of the machine spindle main body 101.
Fig. 13 shows that the free end of the die-loading support arm 62 is in a stepped shaft shape, and as shown in fig. 13, the free end of the die-loading support arm 62 sequentially comprises a die-loading support arm tool withdrawal groove and a support arm stage 622 connected from the outside of the die-loading support arm main body 621 from the inside to the outside, and the diameter of the support arm stage 622 is smaller than that of the die-loading support arm main body 621. The fixed end of the die-filling supporting arm 62 is connected with the upright post assembly 6, and the free end of the die-filling supporting arm 62 is used for extending into or leaving the shaft hole of the rolling die. This allows the roll-type mold to be placed over the mold-holding support arms 62.
When the rolling die is used, equipment such as a crown block is used for lifting the rolling die, and the rolling die is sleeved on the die-filling supporting arm 62 firstly. The roll-type mold is horizontally transferred between the bridge 22 of the spreader and the die-filling support arm 62 by bridging the bridge to the die-filling support arm 62 such that the top surface of the bridge 22 and the top surface of the die-filling support arm 62 are horizontally aligned. Hoisting machine constructs 1 and drives overlap joint 22 and remove the roll-type mould to board main shaft department, and hoisting machine constructs 1 again with overlap joint towards the board main shaft, and overlap joint 22 overlap joint is to the board main shaft on, makes the top surface of overlap joint 22 and the top surface level of board main shaft align, and the roll-type mould is horizontal transfer between the two. Because the lifting appliance mechanism 1 drives the lifting appliance to move along the length direction of the bearing beam 7, the moving distance of the lifting mechanism 1 is reduced by the tool line, and compared with the prior art, the large lifting mechanism 1 such as a crown block is not needed. The hoisting mechanism 1 can be vertically stretched, so that the lifting appliance can be conveniently driven to avoid obstacles near the roll forming machine.
In a preferred embodiment of the present invention, fig. 1 shows the structure of the spreader of the present invention, and as shown in fig. 1, the spreader comprises: a lifting appliance main shaft 2 and a supporting frame.
The hanger main shaft 2 comprises a convex part 23, a lapping part 22 and a hanger main shaft part 21 in sequence. One end of a protruding part 23 of the lifting appliance main shaft 2 firstly extends into a shaft hole of the rolling mould, the lifting appliance main shaft part 21 supports the rolling mould, and one end, far away from the protruding part 23, of the lifting appliance main shaft part 21 is fixedly connected with a supporting frame and used for blocking the rolling mould. The hoisting mechanism 1 hoists the hoisting tool main shaft 2 through the top of the connecting support frame. The rolling die passes through the lapping part 22 and the main shaft part 21 of the lifting appliance to be at the same height, namely the rolling die and the main shaft part of the lifting appliance do not require the same shape and the same appearance, and the rolling die can be ensured to horizontally pass through the main shaft 2 of the lifting appliance as long as the top surfaces of the rolling die and the top surfaces of the rolling die, which are in contact with the shaft hole, are at the same horizontal height.
When the lap joint portion 22 is lapped on the die-filling support arm 62, the die-filling support arm main body 621 restricts the horizontal movement distance of the lap joint portion 22 in the horizontal direction, and seamless butt joint between the two is realized. The protruding portion 23 is placed in the support arm relief groove. Since the outside diameter of the support arm relief is smaller than the outside diameter of the die-fill support arm body 621 and the die-fill support arm stage 622. The protruding part 23 extends from one end of the hanger main shaft 2 to the ground direction, and the width of the protruding part is matched with that of the supporting arm tool withdrawal groove, so that the supporting arm tool withdrawal groove can hook the protruding part 23, and the axial position play between the supporting arm tool withdrawal groove and the protruding part is prevented. And the height of the rolling die supported by the hanger main shaft 2 is the same as the height of the rolling die supported by the die-filling support arm 62 for the rolling die to horizontally move from between the die-filling support arm 62 and the hanger main shaft 2.
When the lapping section 22 is lapped on the machine main spindle stage 102, the machine main spindle body 101 limits the horizontal moving distance of the lapping section 22 in the horizontal direction, thereby realizing seamless butt joint between the two. Meanwhile, the protrusion part 23 is arranged in the machine tool withdrawal groove and used for hooking the machine tool withdrawal groove by the protrusion part 23, and the specific principle is the same as that of arranging the protrusion part 23 in the die-filling support arm withdrawal groove, and is not repeated here. And the height of the rolling mould supported by the lifting appliance main shaft 2 is the same as that of the rolling mould supported by the machine table main shaft, so that the rolling mould can horizontally move from the lifting appliance main shaft 2 to the machine table main shaft. As shown in fig. 6, when overlapping, the overlapping portion 22 overlaps with the top surface of the machine table spindle stage 102, and the top surface of the hoist spindle 2 is horizontally aligned with the top surface of the machine table spindle main body 101. The distances from the axis of the machine main spindle stage 102 to the top surface of the lap part 22 and the outer surface of the machine main spindle body 101 are made equal. That is, a distance B from the axis of the machine table main-shaft stage 102 to the top surface of the lap 22 shown in fig. 6 is equal to a distance a from the axis of the machine table main-shaft stage 102 to the outer surface of the machine table main-shaft main body 101. The spreader spindle 2 is brought into contact with the machine table headstock stage 102 from above the machine table spindle in an overlapping manner. The rolling die can be smoothly and horizontally transferred between the lifting appliance main shaft 2 and the machine table main shaft main body 101.
In a preferred embodiment of the present invention, the hanger main shaft 2 is a cylinder with an opening at one end, the outer surface of the protruding portion 23, the outer surface of the hanger main shaft portion 21 and the outer surface of the overlapping portion 22 are coaxially arranged, and the outer diameter of the overlapping portion 22, the outer diameter of the protruding portion 23 and the outer diameter of the hanger main shaft portion 21 are all equal. Thus, the rolling die on the hanger main shaft 2 moves without being hindered when moving from the boss portion 23 to the hanger main shaft portion 21. As shown in fig. 1 and 4, but the overlapping portion 22 and the protruding portion 23 are each shaped as a partial cylinder, and from the complete horizontally placed cylinder, the partial cylinder is cut out in the axial direction of the cylinder in the horizontal plane at one end portion, and the partial cylinder is further cut out in the direction perpendicular to the cutting plane just before, thus forming the overlapping portion 22. The outer end of the overlapping portion 22 continues to extend outward in the axial direction while extending toward the center of the circle or toward the ground, resulting in a protruding portion 23. It should be understood by those skilled in the art that the angle of the arc formed by the bridging portion 22 in the axial cross-section is less than 180 °, and the arched bridging portion 22 is more uniformly stressed and pressure-resistant.
Preferably, the inner diameter of the overlapping portion 22 is larger than that of the hanger main shaft portion 21, and the inner diameter of the protruding portion 23 is smaller than that of the overlapping portion 22. Thus, a space is formed between the main shaft portion 21 of the hanger and the protrusion portion 23, which is convenient for accommodating the machine table main shaft stage 102 or the mold supporting arm stage 62, and is beneficial for positioning the machine table main shaft stage 102 or the mold supporting arm stage 622 during lapping.
In a preferred embodiment of the invention, the axis of the mold support arm 62 is at a lower level than the machine spindle. This lowers the height of the die-holding arms 62 to facilitate the insertion and removal of the roll-type die into and out of the die-holding arms 62.
In a preferred embodiment of the present invention, as shown in fig. 7, the outer diameter of the overlapping part 22 is equal to the outer diameter of the machine spindle, i.e., the outer diameter of the machine spindle main body, and the inner diameter of the overlapping part 22 is equal to the outer diameter of the machine spindle head stage 102, so that the overlapping therebetween is stable.
Similarly, as shown in fig. 14, the outer diameter of the bridge 22 is equal to the outer diameter of the die-holding-arm main body 621 of the die-holding arm 62, and the inner diameter of the bridge 22 is equal to the outer diameter of the die-holding-arm stage 622. Thus, the two are mutually attached, and the lap joint is more stable.
In a preferred embodiment of the present invention, the outer diameter of the overlapping part 22 is smaller than that of the main shaft of the machine table. Fig. 5 shows a schematic side view of the lapping of the spreader spindle and the machine spindle, and as shown in fig. 5, the size of the spreader spindle 2 is smaller than that of the machine spindle. In this case, the inner surface of the arc of the overlapping part 22 is not in contact with the hanger main shaft, but both sides of the inner surface and the outer surface of the overlapping part 22, which are both arc surfaces, are connected. As shown in fig. 4, since the side surface is not easily processed, a flat surface may be used instead of the side surface in practical use. It is easy to think that in the present embodiment, the outer surface of the protruding portion 23 is still the outer surface of the spreader spindle 2, but the inner portion of the protruding portion 23 is not a cylinder but a plate extending to the ground, and the thickness is the same as that of the machine tool withdrawal groove or the die loading support arm withdrawal groove. The embodiment reduces the size of the lifting appliance main shaft 2 and reduces the load of the lifting device. And the size of the lifting appliance main shaft 2 is smaller than that of the machine table main shaft, more operation space exists between the lifting appliance main shaft 2 and the shaft hole of the rolling type die, the rolling type die can be sleeved on the lapping part 22 quickly, the rolling type die is in contact with the lifting appliance main shaft 2 with small outer diameter, the contact area is small, and the friction force is also reduced. And the main shaft part 21 of the hanger and the main shaft table stage 102 of the machine table are not coaxial, compared with the prior art, the requirement for coaxiality of the main shaft part 21 of the hanger and the main shaft table stage 102 of the machine table is reduced. The lifting appliance main shaft in the prior art is screwed with the machine table main shaft through threads, the invention does not need to arrange the screwing way, only needs to use the lifting mechanism 1 to place the lap joint part 22 on the step section 12, and has simple and rapid operation.
Similarly, as shown in fig. 12, the inner diameter of the bridge 22 is greater than the outer diameter of the mold support arm stage 622. The overlapping is realized by the contact of the top of the outer arc surface of the mold supporting arm stage 622 and the top of the inner arc surface of the overlapping part 22. The top of the outer surface of the bridge 22 and the top of the outer surface of the molded support arm body 621 are horizontally aligned. Therefore, the size of the die-filling supporting arm 62 can be reduced, materials can be saved, the contact area between the die-filling supporting arm 62 and the rolling die can be reduced, and the friction force is reduced.
The overall outer diameter of the machine main shaft is larger than the outer diameter of the lifting appliance main shaft 2, and the outer diameter of the lifting appliance main shaft 2 is larger than the dimension of the die-filling supporting arm 62, so that the axial position of the die-filling supporting arm 62 on the horizontal line is lower than that of the machine main shaft. When the lifting appliance main shaft 2 leaves from the die-filling supporting arm 62, the lifting appliance main shaft only needs to be lifted, and then the lifting appliance main shaft falls onto the machine table main shaft. The spreader spindle is lifted a little distance away from the machine spindle and then dropped onto the flip-chip support arm 62. The operation of the lifting appliance main shaft 2 is simple.
In a preferred embodiment of the present invention, the spreader spindle 2 further comprises a stop pin 24, and the stop pin 24 is detachably connected to the spreader spindle 2. As shown in fig. 5, the hoist main shaft 2 is provided with a stopper pin hole 25, and when the stopper pin 24 is inserted into the stopper pin hole 25, a part thereof is exposed to the outside of the hoist main shaft 2. The rolling die is arranged between the stop pin 24 and the support frame, so that the rolling die can be prevented from falling. The stop pin hole 25 is a blind hole, and the diameter of the stop pin hole is larger than that of the stop pin 24, so that the stop pin and the stop pin can be detachably connected.
In a preferred embodiment of the present invention, fig. 3 shows a side view structure of the support frame of the present invention, and as shown in fig. 1 and 3, the support frame includes a support shaft 31 arranged in parallel with the axis of the hanger main shaft portion 21, a vertical support plate 32 vertically and fixedly connecting the same side of the support shaft 31 and the hanger main shaft portion 21, and a hanging ring 33. Fig. 2 shows the main structure of the hanging ring 33, and as shown in fig. 2, the hanging ring 33 is provided with a first inner hole 331 through which the support shaft 31 passes. The hanging ring 33 is fixedly connected with the supporting shaft 31, and a second inner hole 332 is formed in the hanging ring 33 and is convenient to be hung by a hoisting mechanism.
In a preferred embodiment of the present invention, the hanging ring 33 and the supporting shaft 31 are horizontally movable, so that the hanger increases the function of a counterweight. For rolling dies with different weights, the distance between the hanging ring 33 and the supporting shaft 31 can be adjusted, so that the hoisting position can be changed. Furthermore, the supporting frame further comprises a top thread 34 arranged on the hanging ring 33, the top thread 34 penetrates through the hanging ring 33 to be in contact with the supporting shaft 31, and the top thread 34 is screwed or loosened to control the position of the supporting shaft 31 relative to the hanging ring 33. The hoisting process of the profile roller is basically balanced, so that the smooth lapping of the main shaft of the lifting appliance and the main shaft of the machine table is facilitated. The use of the jack screw 34 is well known in the mechanical arts and will not be described in detail herein.
In a preferred embodiment of the present invention, the support plate 32 is provided with a handle 321 for manual control of the position of the spreader, which can be rotated manually.
Preferably, a support rod is arranged between the other end of the carrier beam 7 and the top of the roll forming machine, and the support rod is fixedly connected with the carrier beam. The design is that the bearing beam 7 is supported by the roll forming machine, so that the stress of the bearing beam 7 can be reduced, and the cantilever beam is more stable.
Preferably, the carrier bar 7 and the column assembly 6 are fixed on the ground by the foundation bolt through the two-body column assembly 6, one end of the carrier bar 7 is supported on the column assembly 6, and the carrier bar 7 and the column assembly are detachably connected through a quick-change connecting structure such as a screw. The other end of the bearing beam 7 is supported on the main body frame of the roll forming machine through the supporting rod, and during equipment maintenance, the bearing beam 7, the supporting rod and the electric hoist can be integrally detached and are convenient to transport.
Preferably, the hoisting mechanism 1 is an electric hoist, and a lifting hook head of the electric hoist is connected with the support frame. The electric hoist is small in structure, sensitive in movement and higher in precision. The lifting hook head has the rotation ability can drive the hoist free rotation. The electric hoist can move on the bearing beam 7; when the motion control button is released, the electric hoist can be locked at any position. The electric hoist has a fast and slow moving function, can adopt a fast function in the process of the previous lap joint position, can adopt a slow function when the lap joint is needed, and can adopt a braking function when the lap joint is completed. It is easy to think that, when hoisting machine constructs 1 for the electric hoist, the structure of carrier bar 3 is the rail structure that uses with the cooperation of electric hoist, and it is the prior art of machinery to realize the removal of electric hoist, and it is no longer repeated here.
The lifting appliance main shaft, the machine table main shaft and the die filling supporting arm are designed on the same vertical surface, and the running route of the lifting appliance main shaft can be reduced. When the lifting hook head capable of freely rotating is used, the lifting appliance is manually rotated for 180 degrees, so that the rolling die faces to or is away from the main shaft of the machine table in parallel; for the hook head without free rotation function, it is easy to think that the chain or the rope is used to connect the main shaft of the lifting appliance in the field, and the main shaft of the lifting appliance can still be rotated manually, and the lifting mechanism 1 with rotation function in the prior art is used. The main shaft of the lifting appliance is rotated to enable the lap joint end of the main shaft of the lifting appliance to be respectively lapped with the main shaft of the machine table and the die-filling supporting arm.
In a preferred embodiment of the present invention, fig. 11 shows the structure of the pillar assembly 6, and as shown in fig. 11, the pillar assembly 6 comprises a pillar shaft 60, a rotating sleeve 61 and a mold supporting arm 62, wherein the rotating sleeve 61 is sleeved outside the pillar shaft 60; the fixed end of the die-filling supporting arm 62 is fixedly connected with the rotating sleeve 61, and the free end of the die-filling supporting arm 62 is used for extending into or leaving the shaft hole of the rolling die. The rotating sleeve 61 is rotatable relative to the axis of the column shaft 60 and rotates to a first position, the die-filling support arm 62 faces the machine main shaft and is parallel to the machine main shaft, and then the electric hoist starts to work.

The die-filling support arm 62 is parallel to the machine main shaft, and the die-filling support arm 62 faces the machine main shaft; and the unloading support arm 63 is positioned at the outer side of the cantilever beam and can simultaneously receive the second external rolling die, so that the die change efficiency is improved. When the rotary sleeve 61 rotates to the second position, the die-filling support arm 62 is parallel to the machine main shaft, and the die-filling support arm 62 is far away from the machine main shaft, the rolling die on the die-filling support arm 62 can be ready to be moved down, and the rolling die on the die-unloading support arm 63 starts the next cycle. Therefore, the cantilever beam improves the production efficiency.

The stripper support arms 63 can be used to lap a new upper mold during the transfer of the upper mold from the roll forming machine to the mold-loading support arms 62. When the die-loading supporting arm 62 rotates 180 degrees, the die-unloading supporting arm 63 rotates to a first position facing the main shaft of the machine table.
The new upper mold is then rotated to the first position by the unload support arm 63.

The tool for replacing the rolling die is changed from overhead travelling crane to cantilever crane operation, so that the potential safety hazard is reduced. The lap joint mode is applied, the problem that the lifting hook and the machine table main shaft need to be coaxially sleeved is not involved, and the requirement on the lifting precision is reduced. And the mould unloading supporting arm 63 or the mould loading supporting arm 62 and the lifting hook are also in a lap joint mode, and the requirement on the lifting precision is also reduced in the same way. Before the cantilever crane works, the prior art is only used for sleeving the rolling mould on the mould unloading supporting arm 63 or the mould loading supporting arm 62. The use of a crown block can be reduced or even cancelled in the sleeving process, and the safety performance is improved.
