Description

Technical Field

[0001] The invention relates to the field of stamping and forming dies, and in particular to a stamping die with a mechanism for suppressing deformation of a workpiece after forming. Background Art

[0002] A stamping die is a special process equipment used to process metal materials into parts during cold stamping, so it is also called a cold stamping die.

[0003] In the current stamping dies, after the workpiece is stamped and formed, it is easy for the workpiece to deform during stripping and picking up due to the thinness of the forming and edge connections. It will need to be reshaped later. If the reshaping cannot overcome the deformation problem, it will become waste, which will also cause a lot of burden on production costs. Summary of the invention

[0004] In view of this, the present invention provides a stamping die with a mechanism for suppressing deformation of a workpiece after forming, which can effectively overcome the deformation problem of the forming part and the edge connection when stripping and taking the workpiece.

[0005] To this end, the present invention provides a stamping die having a mechanism for suppressing deformation of a workpiece after forming, comprising:

[0006] The upper die mechanism comprises an upper die base, an upper pad and an upper clamping plate, wherein the upper pad is fixedly arranged on the upper die base, the upper clamping plate is fixedly arranged on the upper pad, and a forming punch is arranged on the upper clamping plate;

[0007] The lower die mechanism comprises a lower supporting plate, a lower cushion block and a lower die base, wherein the lower cushion block is fixedly arranged on the lower supporting plate, and the lower die base is fixedly arranged on the lower cushion block;

[0008] The deformation suppression mechanism comprises two symmetrically arranged deformation suppression components, the deformation suppression components comprise a mounting seat and a rocker arm, the first end of the rocker arm is connected to the mounting seat via a rotating shaft, and a reset component is mounted on the rotating shaft, the second end of the rocker arm has a conical surface, the edge of the workpiece is placed on the positioning plane of the conical surface, the rocker arm swings within an angle range of 10-19 degrees, and the workpiece is removed from the material due to the swing of the rocker arm after stamping.

[0009] Furthermore, two limit assemblies are installed on the above-mentioned mounting seat, and the swing arm swings back and forth between the two limit assemblies.

[0010] Furthermore, the above-mentioned limiting assembly includes at least two limiting axes arranged in a straight line.

[0011] Furthermore, the above-mentioned limiting shaft is a pin shaft.

[0012] Furthermore, an angle between the first side of the conical surface and the side surface of the swing rod is between 115° and 123°.

[0013] Furthermore, an angle between the second side of the conical surface and the side surface of the swing rod is between 107° and 114°.

[0014] Furthermore, the tapered surface has a tapered end angle of 87-91°.

[0015] Furthermore, the above-mentioned reset component is a spring.

[0016] The present invention provides a stamping die with a deformation suppression mechanism after workpiece forming, which prevents the workpiece from falling off after forming and deformation of the workpiece forming part and edge connection when taking the workpiece by setting a deformation suppression mechanism;

[0017] The specific working principle is as follows: when the mold is closed, after the workpiece is punched and formed by the punch, its edge part is supported on the positioning plane of the swing rod, and the positioning plane of the swing rod is in a horizontal state when the mold is closed; when the mold is separated, the punch leaves the product, and the swing rod is reset by the reset function of the reset component, and the angle begins to change. When the change is close to 3°, the workpiece can be separated from the lower mold mechanism, and the robot or the worker can take the workpiece from the mold, because there is no need to directly remove or take the material, and the workpiece is loosened by changing the angle of the swing rod, which can effectively prevent the ejector or ejector block from having too much impact on the workpiece when removing the material, causing the edge to break, and the control of the swing angle of the swing rod (10-19°) can also effectively prevent the swing force caused by the swing angle of the swing rod being too large, and can prevent the swing rod from damaging the workpiece;

[0018] Therefore, compared with the prior art, the present invention can effectively overcome the deformation problem of the forming part and the edge connection when removing the material and taking the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
