DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
Specific embodiments of the present invention are described below with reference to the accompanying drawings.
The following examples exemplify the case where the terminal is a high-voltage terminal having a large plate thickness.
First embodiment
An apparatus for manufacturing a chain terminal according to a first embodiment of the present invention is described with reference to fig. 1 to 4.
The manufacturing apparatus of this embodiment includes a primary link end processing portion and a secondary link end processing portion.
First, as shown. Referring to fig. 1 to 3, a primary link end processing part presses a link terminal from a first metal plate having a large plate thickness, the link end including a band plate-shaped chain portion 10 and a plurality of terminals 1 joined to the chain portion 10 via a joint 2. During the pressing, two guide holes (small holes) 12 for each terminal 1 are formed on the chain portion 10.
Next, the secondary link end processing section separates the chain portion 10 processed by the primary link end processing section into each terminal 1 in its longitudinal direction (mode in fig. 1 to 3). Then, the separated chain portion 10 is connected to the other slat-type link plate member 20 formed of the second metal plate by fitting the convex portion and the small hole formed in the plate thickness direction, thereby forming the chain again.
That is, in processing the link plate member 20, the convex portion 22 corresponding to the guide hole 12 of the chain portion 10 is provided on the link plate member 20. Then, the two guide holes 12 are fitted to the link plate members 20, respectively, and the convex portions 22 are swaged. In this way, the new link plate 20 and the terminal 1 are connected by the separated chain portion 10.
As shown in fig. 3, the terminal 1 with the separated chain portion 10 mounted thereon is pushed and moved by the pushing member N1 to be positioned on the new link plate member 20. Then, the two positioning holes 12 provided on the chain portion 10 are fitted on the two protrusions 22 on the new link plate 20, and the protrusions 22 are swaged by the swaging members N2 and N3 in this state so that the terminal 1 can be engaged to the link plate member 20 via the separated chain portion 10. This completes the chain terminal formed of the composite member in which the terminal 1 is made of the first metal plate having a large plate thickness and the chain portion (link plate member 20) is made of the second metal plate having a small plate thickness. Here, the convex portion 22 may be formed by burrs or may be formed by pins.
Fig. 4 is a block diagram of a manufacturing system 200 including the manufacturing apparatus of the present embodiment.
As shown in a of fig. 4, the manufacturing system 200 is configured centering on a continuous molding press device 100 as a manufacturing device of a link end of the present embodiment, and includes a material supply device 101, a material feeding device 102, a product discharge device 104, and a product winding device 105. The material supply device 101 supplies the material of the terminal 1. In the present embodiment, the material of the link plate member 20 is provided in addition to the material of the supply terminal 1. The material feeding device 102 supplies the material supplied from the material supply device 101 to the pressing device 100. The stamping apparatus 100 forms chain terminals as products manufactured by the manufacturing system 200. The product manufactured by the punching device 100 is discharged by the product discharge device 104 and wound by the product winding device 105. In the present embodiment, as shown in B of fig. 4, the pressing device 100 is provided with a terminal forming portion 131 serving as a primary link end processing portion, a burr portion 132 serving as a secondary link end processing portion, and a coupling portion 133. The terminal forming portion 131 forms a plurality of terminals 1 that are joined to the chain portion 10 via the joining portion 2. The burr portion 132 forms the convex portion 22 on the link plate member 20. The coupling portion 133 separates the chain terminal processed by the terminal forming portion 131 into terminals 1 in its longitudinal direction, and swages the chain end in a state where the two guide holes 12 of the chain portion 10 are fitted to the two convex portions 22 (see fig. 2 and 3). In this way, the chain terminals are manufactured in the press apparatus 100.
According to the above-described configuration, the terminal 1 processed by the terminal forming portion 131 as the primary link end processing portion is formed into a chain by using the link plate member 20 having a smaller plate thickness than the terminal 1, which makes it possible to make the rigidity of the portion constituting the chain (link plate member 20) smaller than that of the portion constituting the terminal 1. Therefore, the burden of winding the chain portion (link plate member 20) can be reduced. Further, by winding the chain portion (link plate member 20) having a small plate thickness, the occurrence of winding curl can be reduced, and the burden of correcting the winding curl in the subsequent step can be reduced or eliminated. That is, the terminal 1 can be supplied in a chain state to a subsequent process, for example, continuous plating. In addition, this enables winding without curling, and thus the process of correcting curling can be eliminated. Further, by engaging and swaging the two guide holes 12 and the two protrusions 22 as in the embodiment, the rotation of the terminal 1 can be restricted even if the guide holes 12 and the protrusions 22 are circular.
The materials of the terminal 1 and the link plate member 20 as the product may be set separately, but are preferably the same.
Second embodiment
An apparatus for manufacturing a chain terminal according to a second embodiment of the present invention will be described with reference to fig. 5 and 6. The differences from the first embodiment will be mainly described below.
In the second embodiment, as shown in fig. 5 and 6, a primary link end processing portion presses a link terminal from a first metal plate having a large plate thickness, the link end including a band-shaped link portion 10 and a plurality of terminals 1 connected to the link portion 10 by engagement of an engagement portion 2. During this pressing, for each terminal 1, a square small hole 15 is formed in the chain portion 10. Square apertures 15 are preferably located on the extension of terminal 1.
Next, the secondary link end processing section separates the chain portion 10 of the chain terminal treated by the primary link end processing section into terminals 1 having an appropriate width. Then, by fitting and swaging the convex portions and the small holes formed in the plate thickness direction, the separated portions of the chain portion 10 are connected with the band plate-shaped link plate member 20 composed of the second metal plate smaller in plate thickness than the first metal plate, thereby forming the chain again.
That is, in processing the link plate member 20, the square protrusion 25 corresponding to the square small hole 15 of the chain portion 10 is provided on the link plate member 20. Then, the square small hole 15 is fitted to the square convex portion 25 to swage the convex portion 25 by a swaging member. In this way, the new link plate member 20 and the terminal 1 can be connected by the separated portion of the chain portion 10.
In this case, the same effects as those of the first embodiment can be obtained. Further, by fitting and swaging the square small hole 15 and the square convex portion 25, the rotation of the terminal 1 can be restricted by the combination of one convex portion 25 and the small hole 15. Since it is sufficient to separate the chain portion 10 in a size including one small hole 15, the separation size of the chain portion 10 can be minimized. As a result, the overlapping dimension of the split chain portion 10 when engaged with the link plate member 20 can be reduced, which reduces the resistance caused by the thick split chain portion 10 when winding the link plate member 20.
Third embodiment
An apparatus for manufacturing a chain terminal according to a third embodiment of the present invention will be described with reference to fig. 7 to 8. The cross-sectional view taken along line A-A, the cross-sectional view taken along line B-B, and the cross-sectional view taken along line C-C in fig. 7 correspond to the respective views along lines A-A, B-B, and C-C in fig. 8.
Hereinafter, differences from the first embodiment will be mainly described.
In the third embodiment, as shown in fig. 7 and 8, a primary link end processing portion presses a link terminal from a first metal plate having a large plate thickness, the link end including a band-shaped link portion 10 and a plurality of terminals 1 joined to the link portion 10 by a joint portion 2. During this pressing, a small hole 13 is formed in each joint 2.
Next, the secondary link end processing section cuts the joint 2 of the chain terminal processed by the primary link end processing section at a position near the chain portion 10, and separates the terminal 1 from the chain portion 10 while holding the joint 2. Then, fitting and swaging are performed by the convex portions and the small holes formed in the plate thickness direction, so that the separated joint portion 2 is joined with the other band plate-shaped link plate member 20 made of the second metal plate smaller in plate thickness than the first metal plate, thereby forming the chain again.
That is, in processing the link plate member 20, the square protruding portion 23 corresponding to the small hole 13 of the joint portion 2 is provided on the link plate member 20. Then, the small hole 13 is fitted to the convex portion 23 to swage the convex portion 23 by a swaging member. In this way, a new link plate 20 and terminal 1 can be connected by the joint 2.
In this case, the same effects as those of the first embodiment can be obtained. Further, since the terminals 1 are not separated at the chain portion 10 but separated at the engaging portion 2, the resistance when the link plate member 20 is wound can be further reduced.
In the first to fourth embodiments, the convex portions 22, 23 and 25 are formed in the link plate member 20 having the small plate thickness, and the small holes 12, 13 and 15 are formed in the chain portion 10 and the engaging portion 2 having the large plate thickness, but may be reversed. That is, the convex portions 22, 23, 25 can be formed on the chain portion 10 or the engaging portion 2 having a large plate thickness, and the small holes 12, 13, 15 can be formed in the link plate member 20 having a small plate thickness.
Fourth embodiment
An apparatus for manufacturing a chain terminal according to a fourth embodiment of the present invention will be described with reference to fig. 9 to 10. Hereinafter, differences from the first embodiment will be mainly described.
The manufacturing apparatus of the present embodiment includes a terminal forming portion and a groove forming portion (corresponding to a chain portion processing portion). These parts may be incorporated into a single stamping apparatus.
First, as shown in fig. 9, the terminal forming portion forms a chain end having a band plate-shaped chain portion 10 and a plurality of terminals 1 joined to the chain portion 10 via a joint 2 from one metal plate.
Next, as shown in fig. 10, the groove forming portion continuously forms a plurality of V-shaped grooves (grooves) 17 in the width direction on the surface of the chain portion 10 in the length direction, thereby reducing the bending rigidity in the longitudinal direction of the strip-shaped chain portion 10. That is, by forming a large number of V-shaped grooves 17 in the chain portion 10, locally thinned portions are intermittently provided in the coupling portion in the length direction. Therefore, even if the plate thickness before pressing is large, the chain portion 10 can be easily bent, and winding without curling can be performed.
Fifth embodiment
An apparatus for manufacturing a chain terminal according to a fifth embodiment of the present invention will be described with reference to fig. 11. Hereinafter, differences from the first embodiment will be mainly described.
The manufacturing apparatus of the present embodiment includes a terminal forming portion and an opening forming portion (corresponding to a chain portion processing portion). These parts may be incorporated into a single stamping apparatus.
First, as shown in fig. 11, the terminal forming portion forms a chain terminal having a band plate-shaped chain portion 10 and a plurality of terminals 1 joined to the chain portion 10 via a joint 2 from one metal plate.
Next, the groove forming portion forms a plurality of thinned openings 16 in the strip-shaped chain portion 10 for reducing bending rigidity in the longitudinal direction of the chain portion 10. Therefore, even if the plate thickness before pressing is large, the chain portion 10 can be easily bent, which enables winding without curling. The thinned opening 16 is provided only by removing a predetermined shape from the chain portion 10, and thus its load is small. The position where the thinning opening 16 is provided is not limited, but the stress can be reduced by providing the thinning opening 16 in a balanced manner. The thinned opening 16 is provided separately from the guide hole.
Sixth embodiment
An apparatus for manufacturing a chain terminal according to a sixth embodiment of the present invention will be described with reference to fig. 12 and 13. Hereinafter, differences from the first embodiment will be mainly described.
The manufacturing apparatus of the present embodiment includes a plate member engaging portion (corresponding to a chain portion processing portion) and a terminal forming portion.
First, as shown in fig. 12 and 13, the plate member joining portion performs laser joining (joining portion: ls) on the side edges of the first metal plate 10S having a large plate thickness and the second metal plate 20S having a smaller plate thickness than the first metal plate 10S, thereby forming a single plate member including two regions having different plate thicknesses. Then, the punching device serving as a terminal forming portion forms the band plate-shaped chain portion 20P from the second metal plate 20S, and forms the plurality of terminals 1 joined to the chain portion 20P via the joining portion 2 from the first metal plate 10S. In this way, the chain portion 20P is easily bent, which enables winding without curling.
Seventh embodiment
A manufacturing apparatus of a chain terminal according to a seventh embodiment of the present invention is described below with reference to fig. 14 to 16. Hereinafter, differences from the first embodiment will be mainly described.
The manufacturing apparatus of the present embodiment includes a terminal forming portion and a plate thickness reducing portion.
First, as shown in fig. 14, the terminal forming part forms a chain terminal from a metal plate having a constant plate thickness, the chain end having a band-shaped chain portion 10 and a plurality of terminals 1 joined to the chain portion 10 by a joint 2. Next, as shown in fig. 15, the plate thickness of the plate-like chain portion 10 is reduced by a cutter or grinder 110 as a plate thickness reduction portion at a stage before winding the chain ends on the drum 80. Therefore, as shown in fig. 16, winding the thinned chain portion 10A around the drum 80 makes the chain portion 10A easy to bend, which enables winding without curling.
Eighth embodiment
An apparatus for manufacturing a chain terminal according to an eighth embodiment of the present invention is described below with reference to fig. 17.
The manufacturing apparatus of the present embodiment has the same effect as the seventh embodiment, except that the plate thickness of the chain portion 10 is reduced by using the setting 70 including the rollers 71, 72, and 73 as the plate thickness reducing portion.
Ninth embodiment
A manufacturing apparatus of a chain terminal according to a ninth embodiment of the present invention is described below with reference to fig. 18 to 22. Fig. 19 is a cross-sectional view taken along line A-A in fig. 18. Fig. 21 is a cross-sectional view taken along line B-B in fig. 20.
The manufacturing apparatus of the present embodiment includes a terminal forming portion and a board width reducing portion. Hereinafter, differences from the first embodiment will be mainly described.
First, as shown in fig. 18 and 19, the terminal forming portion forms a chain terminal from a metal plate having a constant plate thickness, the chain end having a band-shaped chain portion 10 and a plurality of terminals 1 joined to the chain portion 10 by joining portions 2. Next, as shown in fig. 20 and 21, the plate width reduction portion reduces the plate width of the strip-shaped chain portion 10. That is, the original chain portion 10 having the plate width HB1 is molded into the chain portion 10B having the plate width HB2 by the plate width reduced portion.
As a result, the bending rigidity of the strip-shaped chain portion 10 decreases. Therefore, as shown in fig. 22, the chain portion 10B is easily bent, which enables winding without curling.
Tenth embodiment
An apparatus for manufacturing a chain terminal according to a tenth embodiment of the present invention will be described with reference to fig. 23.
The apparatus of this embodiment is a winding apparatus for winding a link end, which is manufactured by a punching apparatus 50 and has a band-shaped chain portion 10 and a plurality of terminals connected to the chain portion by a joint 2, on a drum 80. The winding device has a bending curl applying portion 60 provided in a stage before the winding drum 80 to apply bending curl for winding to the chain portion 10 by a plurality of rollers 61, 62, and 63. As described above, the radius R of the bending curl is adjusted by disposing the plurality of rollers 61, 62, 63. Therefore, even if the plate thickness at the time of winding is large, the chain portion 10 can be easily wound. In addition, at the time of rewinding, the same rollers 61, 62, and 63 may be used as the bending curl removal portion to correct bending curl. The apparatus of the tenth embodiment may be used alone, but by being used in combination with the manufacturing apparatuses of the first to ninth embodiments, for example, by replacing 50 with the punching apparatus 100, a better effect can be obtained.
