Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a shock absorber seat. Background Art

[0002] The stamping process relies on a press and a die to apply external forces to sheets, strips, tubes, profiles, etc., causing plastic deformation or separation to obtain workpieces (stamped parts) with the required shapes and sizes. The die used in the stamping process is called a stamping die, which is a special tool for batch processing materials into required workpieces. The stamping die is crucial in stamping. Without a qualified stamping die, batch stamping production is difficult to carry out.

[0003] The shock absorber seat has a workpiece made of metal, and this workpiece is made by the stamping process. When producing the workpiece of the shock absorber seat, first place the sheet between the upper die and the lower die of the stamping die, and then drive the upper die to move vertically by a pressure device to produce the required workpiece.

[0004] However, in the process of continuously producing workpieces, usually the operator's left hand continuously feeds the sheet, and the operator's right hand receives the formed workpiece and puts it into a container, resulting in a relatively large labor intensity. In addition, when the operator feeds the sheet, usually relying on his own experience to determine the feeding stroke of the sheet, this directly leads to more scrap materials generated during the production process, resulting in more waste of raw materials. Summary of the Invention

[0005] In view of this, the purpose of the utility model is to provide a stamping die for a shock absorber seat to solve the problem pointed out in the background art that when the operator feeds the sheet, usually relying on his own experience to determine the feeding stroke of the sheet, this directly leads to more scrap materials generated during the production process, resulting in more waste of raw materials.

This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the figures are only for illustrative purposes and cannot be understood as a limitation to the present utility model. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0031] As Figures 1 - 5 shown, an embodiment of the present application provides a stamping die for a shock-absorbing seat. The stamping die includes an upper die assembly and a lower die assembly. During operation, a sheet 300 is placed between the upper die assembly and the lower die assembly, and then the upper die assembly is driven to move downward by an external pressure device to process the required workpiece.

[0032] The upper die assembly includes an upper die base 110, an upper template 120, a stripper plate 130, and a punch 140. Among them, the upper template 120 is fixed to the lower side of the upper die base 110, and the stripper plate 130 is slidably mounted along the vertical direction on the lower side of the upper template 120. And an elastic reset member is provided between the stripper plate 130 and the upper template 120. The elastic reset member can be a helical spring, a compression spring, etc. The upper end of the punch 140 is fixed to the lower side of the upper template 120, and the lower end penetrates through the stripper plate 130. In addition, the lower end of the punch 140 has a cutting edge capable of separating the workpiece from the sheet 300.

[0033] The lower die assembly is located below the upper die assembly. The lower die assembly includes a lower die base 210 and a lower template 220. The lower template 220 is fixed to the upper side of the lower die base 210. A positioning block 221 is fixed to the upper side surface of the lower template 220. The positioning block 221 is located behind the punch 140, and a abutting positioning surface 222 for restricting the feeding stroke of the sheet 300 is provided on one side of the positioning block 221 close to the punch 140.

[0034] By adopting the above technical solution, when an operator uses the stamping die, first place the sheet 300 on the lower template 220 and make the end of the sheet 300 abut against the abutting positioning surface 222 of the positioning block 221; then drive the upper die assembly to move downward. The stripper plate 130 will first press on the sheet 300 to fix the sheet 300, and then punch the sheet 300 through the punch 140 to process the workpiece. During subsequent processing, the operator only needs to convey the sheet 300 in the direction close to the positioning block 221 and make the end of the sheet 300 abut against the abutting positioning surface 222 of the positioning block 221, and then repeat the above operations. By setting the positioning block 221, the feeding stroke of the sheet 300 can be restricted, the generation of scrap can be reduced, and thus the cost can be saved.

[0035] It should be noted that in this embodiment, the workpieces for the shock absorber seat are mostly rectangular structures, and the punch 140 is also designed to be adapted to the structure of the workpiece. In addition, there can be some through holes on the workpiece. The punching rod 160 can be installed on the upper template 120 according to actual needs. The lower end of the punching rod 160 penetrates through the stripper plate 130, and blanking holes adapted to the punching rod 160 can be provided on the lower die base 210 and the lower template 220. The punching rod 160 can be arranged on the front side of the punch 140 to separate the punching operation and the operation of separating the workpiece into two steps.

[0036] As Figure 5 shown, before the positioning block 221 is installed, there is more scrap between adjacent workpiece notches 310 on the scrap of the sheet 300 processed by the stamping die; after the positioning block 221 is installed, there is less or no scrap between adjacent workpiece notches 310 on the scrap of the sheet 300 processed by the stamping die. On the same sheet 300, the improved die can process more workpieces.

[0037] In this embodiment, when the punch 140 moves downward, one side of the punch 140 can contact the abutting positioning surface 222 of the positioning block 221. By setting it like this, the workpiece notch 310 is the end of the sheet, and there will be no scrap between adjacent workpiece notches 310 on the scrap of the processed sheet 300, further reducing the generation of scrap and also further saving costs.

[0038] In this embodiment, blanking holes 223 are provided through the lower die base 210 and the lower template 220, and the blanking holes 223 are located directly below the punch 140. By setting it like this, the workpiece separated by the punch 140 can directly fall into the blanking holes 223, and a container for receiving the workpiece can be provided on the lower side of the blanking holes 223. Such a design can reduce the labor intensity of the operator.

[0039] In this embodiment, a first auxiliary feeding part 224 and a second auxiliary feeding part 225 are provided on both sides of the lower template 220, and a feeding channel 226 adapted to the width of the plate 300 is provided between the first auxiliary feeding part 224 and the second auxiliary feeding part 225. With such an arrangement, during processing, the plate 300 can be placed in the feeding channel 226, and the first auxiliary feeding part 224 and the second auxiliary feeding part 225 can prevent the plate 300 from moving in the width direction, thereby assisting the feeding of the plate 300.

[0040] In this embodiment, an extension plate 227 is provided on one side of the first auxiliary feeding portion 224 close to the feeding channel 226, and one end of the extension plate 227 extends to the outside of the feeding channel 226. This arrangement can assist the plate 300 in better feeding.

[0041] In this embodiment, a stop edge 228 is provided on one side of the second auxiliary feeding portion 225 close to the feeding channel 226. By providing the stop edge 228, the plate 300 will not escape from the feeding channel 226 in the vertical direction.

[0042] In this embodiment, a plurality of pressing blocks 131 are provided on the lower side of the stripper plate 130. When the stripper plate 130 moves downward, the pressing blocks 131 can press on the plate 300. By providing the pressing blocks 131, the plate 300 can be fixed by the pressing blocks 131 before the punch 140 is used to separate the workpiece on the plate 300, thereby better assisting the operation of separating the workpiece.

[0043] In this embodiment, a plurality of guide posts 121 are fixed to the lower side of the upper template 120, and a guide hole adapted to the guide posts 121 is provided on the stripper plate 130, and the guide posts 121 pass through the adapted guide hole. Through the mutual cooperation between the guide posts 121 and the guide hole, the stripper plate 130 is slidably installed on the lower side of the upper template 120 in the vertical direction. In addition, a retaining ring is also provided on the guide post 121 to prevent the guide post 121 from being separated from the guide hole.

[0044] In this embodiment, a blind hole 229 adapted to the guide column 121 is provided on the lower template 220 . When the guide column 121 moves downward, the lower end of the guide column 121 can enter the blind hole 229 adapted thereto.

[0045] In this embodiment, the upper mold assembly further includes a pad 150, and the pad 150 is installed between the upper mold base 110 and the upper mold plate 120. By providing the pad 150, the upper mold plate 120 can be protected to a certain extent.
