Embodiment 1

[0025] see Figure 1 to Figure 5 , the figure shows a stamping die for punching and riveting one-time forming provided by Embodiment 1 of the present invention, including:

[0026] Upper mold mechanism 1, which includes an upper template 11, an upper punch 12 is provided at the bottom of the upper template 11, and a forming bump 121 is provided on the bottom end surface of the upper punch 12;

[0027] The lower mold mechanism 2 includes a lower template 21, the first strip 3 and the second strip 4 are fed in a cross mode on the lower template 21, the lower mold 21 is provided with a lower forming male 22, and the lower forming male 22 is elastically connected to the lower mold On the seat 23, the lower forming male 22 is provided with a blanking hole 221 corresponding to the forming bump 121, the lower template 21 is provided with a riveting punch 24, and the riveting punch 24 is arranged on the lower forming male 22, and the bottom of the upper punch 12 A forming groove corr...

Embodiment 2

[0036] see Figure 1 to Figure 5 , the figure shows a punching and riveting stamping die provided by Embodiment 2 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solutions as improvements: upper die base 13 is provided with an anti-misfeed detection needle mechanism, and in the anti-misfeed detection needle mechanism, the anti-misfeed detection needle 7 is elastically connected on the upper mold base 13, and the lower forming male 22 is provided with a guide corresponding to the anti-misfeed detection needle 7. Positive groove 222 ; the guiding groove 222 is tangent to the first strip 3 .

[0037] The stamping die detects whether the position of the lower forming male is correct through the cooperation of the anti-misfeed detection needle and the guide groove, and stops stamping if the position deviates, so as to ensure the accuracy of riveting and punching. In addition, since the guide groove is tangent to...

Abstract

The invention discloses a stamping die capable of achieving blanking and riveting one-time forming. The stamping die comprises an upper die mechanism and a lower die mechanism, wherein the upper die mechanism comprises an upper die plate, an upper punch is arranged at the bottom of the upper die plate, and a forming protruding block is arranged on the end face of the bottom of the upper punch; thelower die mechanism comprises a lower die plate, a first material belt and a second material belt are fed on the lower die plate in a crossed mode, a lower forming male die is arranged on the lower die plate and elastically connected to a lower die base, a blanking hole corresponding to the forming protruding block is formed in the lower forming male die, a riveting punch is arranged on the lowerdie plate and penetrates through the lower forming male die, and a forming groove corresponding to the riveting punch is formed in the bottom end face of the upper punch. According to the stamping die capable of achieving blanking and riveting one-time forming, the blanking and riveting procedures of a material strip are completed through one-time stamping, repeated workpiece positioning is avoided, and the machining precision of products is improved.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die for one-time forming by punching and riveting. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] In the existing process, stamping and riveting are completed in sequence, that is, the two processes are independent, and the workpiece needs to be repositioned before each process is implemented. The process is cumbersome and the machining accuracy is poor. Contents of the invention [0004] In view of this, the present invention provides a stamping die for one-time punching and riveting, which completes the punching and riveting process of the mat...
