Description

Technical Field

[0001] This utility model relates to the field of stamping die structure, and in particular to a blanking mechanism for strip-shaped workpieces in stamping dies. Background Technology

[0002] Currently, cold-pressing dies are widely used in the production of various housing parts for automobiles. For some long strip-shaped workpieces, after the final stamping, they need to be unloaded for further processing. However, due to the large length of these workpieces, manual unloading makes it difficult for operators to lift the entire workpiece from one end. Even if they could lift it, long-term operation would cause significant wrist damage. While robotic arms are used for unloading, they also face several problems, such as high manufacturing costs. Furthermore, to stably lift the workpiece, the robotic arm needs to extend into the die and be positioned in the middle of the workpiece for gripping. The long travel distance of the robotic arm results in low unloading efficiency. Therefore, it is necessary to develop a blanking mechanism for strip-shaped workpieces from stamping dies to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a blanking mechanism for stamping die strip-shaped workpieces to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A blanking mechanism for stamping die strip-shaped workpieces includes an upper die assembly, a lower die plate, an automatic blanking assembly, a support assembly, and a side stamping assembly. The upper die assembly is positioned above the lower die plate. The automatic blanking assembly includes a mounting base plate, connecting blocks, longitudinal metal rods, transverse metal rods, elastic telescopic components, lifting support blocks, and blanking slides. The lower die plate has blanking holes. The mounting base plate is fixed above the lower die plate and corresponds to the left side of the blanking holes. Two sets of connecting blocks are provided and fixed to the front and rear sides above the mounting base plate, respectively. One end of the longitudinal metal rod is fixed to the connecting block, and the other end corresponds to the upper part of the mounting base plate and connects to the left end of the transverse metal rod. The right end of the transverse metal rod protrudes beyond the edge of the mounting base plate and has a prying part. The right end of the prying part is inclined downwards. Two sets of longitudinal metal rods are provided and fixed to two sets of connecting blocks, respectively. The elastic telescopic components are fixed... The support assembly is fixed on the lower template with its elastic telescopic end facing upward. The lifting support block is fixed to the elastic telescopic end of the elastic telescopic component. The lifting support block corresponds between two sets of prying parts. At least two sets of elastic telescopic components and lifting support blocks are provided. The material discharge slide is fixed below the lower template. The left end of the material discharge slide corresponds to the lower end of the material drop hole. The support assembly includes an end support block and a stamping support block. Two sets of end support blocks are provided and fixed at the front and rear ends of the mounting base plate, respectively. The end support block has an upwardly protruding first support boss, which corresponds to the outer side of the prying part. The stamping support block is fixed on the lower template and has an upwardly protruding second support boss, which corresponds between two sets of prying parts. The lateral stamping assembly is fixed on the lower template and corresponds to the right side of the material drop hole. The stamping end of the lateral stamping assembly corresponds to the second support boss.

[0006] Further description of the present invention: The automatic feeding component also includes a limiting block, which is fixed on the lower template and corresponds to the right side of the feeding hole. An arc-shaped guide surface is provided on the upper left side of the limiting block.

[0007] Further description of the present invention: The automatic feeding assembly also includes an adjusting block, which has a strip hole. The adjusting block is fixed to the lower template by a screw passing through the strip hole and is located on the right side of the feeding hole. The position of the adjusting block is adjustable in the left and right direction. The lower end of the limiting block is fixed to the adjusting block.

[0008] The beneficial effects of this utility model are as follows: In the open mold state, under the action of the elastic telescopic component, the lifting support block is in the raised state to place the workpiece to be stamped. When the mold is closed, the upper mold assembly presses on the workpiece and simultaneously drives the lifting support block to descend. The cross-section of the workpiece is inverted U-shaped. When it descends to the point where both ends cover the two sets of first support bosses, the lower left edge of the workpiece presses down on the prying part of the transverse metal rod, thereby causing the prying part to elastically deform and press down. At the same time, the middle part of the workpiece covers the second support boss of the stamping support block. After the mold is closed, the side stamping assembly stamps the right side of the workpiece. After the stamping is completed, the upper mold assembly quickly opens the mold, and the lifting support block is rapidly lifted under the action of the elastic telescopic component, lifting the workpiece to the point of separation from the first and second support bosses. At the same time, the prying part also quickly returns to its original state, thereby exerting a pushing force on the lower left end of the workpiece towards the upper right, thus pushing the workpiece into the blanking hole. The workpiece is collected through the blanking slide, thereby completing the automatic blanking. The advantages of this design are: it can automatically complete the unloading of long workpieces during the mold opening action. The workpiece is unloaded automatically and stably by the thrust generated when the prying part on the horizontal metal rod recovers its deformation. It is not only inexpensive, stable in operation, and efficient in unloading, but also requires no manual intervention, saving labor. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] like Figures 1 to 3As shown, a blanking mechanism for a stamping die strip-shaped workpiece includes an upper die assembly 1, a lower die plate 2, an automatic blanking assembly 3, a support assembly 4, and a side stamping assembly 5. The upper die assembly 1 is disposed above the lower die plate 2. The automatic blanking assembly 3 includes a mounting base plate 31, a connecting block 32, a longitudinal metal rod 33, a transverse metal rod 34, an elastic telescopic member 35, a lifting support block 36, and a blanking slide 37. A blanking hole 21 is provided on the lower die plate 2. The mounting base plate 31 is fixed above the lower die plate 2 and corresponds to the left of the blanking hole 21. On the side, two sets of connecting blocks 32 are provided and fixed on the front and rear sides above the mounting base plate 31 respectively. One end of the longitudinal metal rod 33 is fixed to the connecting block 32, and the other end corresponds to the top of the mounting base plate 31 and is connected to the left end of the transverse metal rod 34. The right end of the transverse metal rod 34 protrudes from the edge of the mounting base plate 31 and is provided with a prying part 341. The right end of the prying part 341 is inclined downward. Two sets of longitudinal metal rods 33 are provided and fixed on two sets of connecting blocks 32 respectively. The elastic telescopic member 35 is fixed. The lifting support block 36 is fixed on the lower template 2 with its elastic telescopic end facing upward. The lifting support block 36 is fixed to the elastic telescopic end of the elastic telescopic member 35. The lifting support block 36 corresponds between two sets of prying parts 341. At least two sets of elastic telescopic members 35 and lifting support blocks 36 are provided. The unloading slide 37 is fixed below the lower template 2, with its left end corresponding to the lower end of the discharge hole 21. The support assembly 4 includes end support blocks 41 and stamping support blocks 42. Two sets of end support blocks 41 are provided and respectively fixed to the mounting base plate 31. At both ends, the end support block 41 is provided with an upwardly protruding first support boss 411, which corresponds to the outer side of the prying part 341. The stamping support block 42 is fixed on the lower template 2, and the stamping support block 42 is provided with an upwardly protruding second support boss 421, which corresponds to the space between the two sets of prying parts 341. The lateral stamping assembly 5 is fixed on the lower template 2 and corresponds to the right side of the blanking hole 21. The stamping end of the lateral stamping assembly 5 corresponds to the second support boss 421.

[0016] In the open mold state, under the action of the elastic telescopic member 35, the lifting support block 36 is in the raised state to place the workpiece to be stamped. When the mold is closed, the upper mold assembly 1 presses on the workpiece and simultaneously drives the lifting support block 36 to descend. The cross-section of the workpiece is inverted U-shaped. When it descends to the point where both ends cover the two sets of first support bosses 411, its lower left edge presses down on the prying part 341 of the transverse metal rod 34, thereby causing the prying part 341 to elastically deform and press down. At the same time, the middle part of the workpiece covers the second support boss 4 of the stamping support block 42. After mold closing, the side stamping assembly 5 stamps the right side of the workpiece. After stamping, the upper mold assembly 1 quickly opens the mold. Under the action of the elastic telescopic member 35, the lifting support block 36 quickly rises and lifts the workpiece to disengage from the first support boss 411 and the second support boss 421. At the same time, the prying part 341 quickly returns to its original shape, thereby exerting a pushing force on the lower left end of the workpiece towards the upper right, thus pushing the workpiece into the blanking hole 21. The workpiece is collected through the blanking slide 37, thus completing the automatic blanking. The advantage of this design is that it can automatically complete the blanking of long strip workpieces with the mold opening action. Through the pushing force generated when the prying part 341 on the transverse metal rod 34 returns to its original shape, the workpiece is automatically and stably blanked. It is not only inexpensive, stable in action, and efficient in blanking, but also requires no manual intervention, saving labor.

[0017] The automatic feeding component 3 also includes a limiting block 38, which is fixed on the lower template 2 and corresponds to the right side of the feeding hole 21. An arc-shaped guide surface 381 is provided on the upper left side of the limiting block 38.

[0018] When the prying part 341 pushes the workpiece to fall into the dropping hole 21, if the thrust is large, the workpiece will move a long distance to the right. At this time, the workpiece collides with the left end of the limiting block 38 and slides to the left into the dropping hole 21 under the guidance of the arc-shaped guide surface 381, thereby ensuring that the workpiece is dropped stably.

[0019] The automatic feeding assembly 3 also includes an adjusting block 39, which has a strip hole 391. The adjusting block 39 is fixed to the lower template 2 by a screw passing through the strip hole 391 and corresponds to the right side of the feeding hole 21. The position of the adjusting block 39 is adjustable in the left and right direction. The lower end of the limiting block 38 is fixed on the adjusting block 39.

[0020] The distance between the limit block and the workpiece can be flexibly adjusted by adjusting block 39, thus adapting to workpieces of different specifications.

[0021] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
