The reed assembly includes a slide connected to the lower mold and an ejector screw connected to the slide; The auxiliary components include a base connected to the lower mold and a protrusion connected to the upper mold.

[0006] Preferably, the set screw is rotatably connected to the top of the lower mold, and the end of the set screw is in contact with the slide block.

[0007] Preferably, the frame assembly further includes a groove formed on the lower mold and the upper mold, and a sliding tongue connected to the lower mold base and the upper mold base, the sliding tongue being slidably connected inside the groove.

[0008] Preferably, the reed assembly further includes a reed body connected to the slide and a first spring connected to the reed body. The reed body is connected to the slide by screws, one end of the first spring is located on the right side of the slide, and the other end of the first spring is connected to the left side of the reed body.

[0009] Preferably, the reed assembly further includes a baffle connected to the lower mold and a buffer pad connected to the baffle, the baffle being connected to the lower mold by a nut.

[0010] Preferably, the auxiliary component further includes a base plate connected to the base and a second spring connected to the base plate, one end of the second spring being fixedly connected to the bottom inner side of the base, the second spring being fixedly connected to the bottom of the base plate, and the protrusion being located directly above the base plate.

[0011] The beneficial effects of this utility model are: 1. This utility model allows for the adjustment of the position of the fixed spring through the slide and set screw, which can be used to adapt to different stamping requirements, improve the versatility of processing, and facilitate the disassembly and replacement of the spring, thereby improving the flexibility of the structure. The first spring can guide, buffer and reset the workpiece to be stamped before and after stamping, which can extend the service life of the spring. 2. The present invention provides auxiliary support and reset capability during the stamping process through the second spring in the auxiliary component, reducing the impact of stamping on the spring assembly. The baffle ensures that the position of the workpiece to be stamped is consistent each time, reducing damage to the spring due to uneven force caused by displacement of the workpiece during the stamping process, and improving the service life of the spring and the stability of processing.
