Description

Technical Field

[0001] This utility model belongs to the technical field of stamping parts processing equipment, and specifically relates to a stamping parts processing mold. Background Technology

[0002] Stamped parts refer to metal parts made by stamping. Stamping is a highly efficient metal forming technology. It uses stamping dies to apply pressure to metal sheets, strips or tubes, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size.

[0003] Stamping dies are crucial tools in the stamping process, determining the shape, size, and precision of the stamped parts. Stamping dies mainly consist of an upper die and a lower die. The lower die is usually fixed on the worktable and works with the upper die to complete the stamping action. The lower die is fixed on the slide block and moves downward during the stamping process to apply pressure to the material.

[0004] However, in actual operation, if the mold surface is uneven or the material surface is not properly treated (such as surface oil, oxide scale, rust, etc.), the contact area between the material and the mold will increase, which will cause the material to stick to the mold surface, so that the stamped material cannot be easily separated from the mold. Therefore, a stamping die is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping die to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die, comprising:

[0032] The lower die assembly 3 also includes a telescopic column 32, a pusher plate 33, and a return spring 34. The material support plate 31 has a mounting hole 314 and a pusher groove 315 on the inner wall forming the stamping groove 311. One end of the telescopic column 32 is fixedly installed on the bottom wall of the mounting hole 314, and the other end of the telescopic column 32 is connected to the lower surface of the pusher plate 33.

[0037] Working principle and usage process of this utility model:

[0038] First, the worker places the material to be stamped horizontally on the upper surface of the support plate 31, and the side of the transfer plate 41 abuts against one end of the material.

[0039] The telescopic rod 12 is compressed downwards, so that the moving plate 22 drives the moving plate 23 and the pressing member 21 inserted in the moving plate 23 to move downwards until the pressing member 21 presses the material on the supporting plate 31, so that the upper and lower surfaces of the material are respectively attached to the pressing member 21 and the stamping groove 311. At this time, the push plate 33 is placed in the push groove 315, and the return spring 34 is compressed.

[0040] Meanwhile, as the moving plate 23 moves to contact the upper surface of the material, the moving plate 22 continues to move downward, compressing the buffer spring 25. In addition, the downward-moving moving plate 23 presses the transfer plate 41 into the limiting groove 313. At this time, the fixing rod 45 and the sliding rod 46 approach each other, and the return spring 44 is compressed. By setting the buffer spring 25 and the return spring 44, damage to the material and the transfer plate 41 during the stamping process is avoided.

[0041] After a stamping operation is completed, the telescopic rod 12 retracts upward, and the moving plate 22 drives the moving plate 23 and the pressing part 21 inserted in the moving plate 23 to move upward; under the action of the rebound force, the return spring 34 drives the push plate 33 to move upward, thereby pushing the material in the stamping groove 311 upward to prevent the material from sticking in the stamping groove 311.

[0042] Simultaneously, the reset spring 44 drives the transfer plate 41 to move upward. The user rotates the handle 47 to make the rotating screw 43 rotate around its own axis, thereby driving the slider 42 in the first slide groove 111 and the transfer plate 41 in the second slide groove 312 to move along the axis of the rotating screw 43. This allows the transfer plate 41 to push one end of the material towards the direction close to the stamping groove 311, so that the pressing part 21 can continue to perform stamping operations on other positions of the material. The operation is simple and not only prevents the downward-moving pressing part 21 from causing injury to the user, but also further prevents the material from sticking to the mold by setting the transfer plate 41.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
