Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die device with a quick-change punch. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] During the operation of stamping dies, the punches are replaced according to actual needs. However, the existing punch connection method is relatively complicated. Generally, workers use special tools to tighten the punches, which is a cumbersome replacement process and causes some trouble. It is not conducive to the quick replacement of punches. In addition, the entire device cannot be quickly disassembled, which causes trouble for later maintenance and replacement. Utility Model Content

[0008] Preferably, the driving mechanism includes two symmetrically arranged through rods that slide through and slide between the placement groove and the outer wall of the connecting pipe. One end of the two through rods located in the placement groove is connected to the connecting strip, and the other end of the two through rods is provided with a fixing plate.

[0009] Preferably, a rotating ring is rotatably connected to the lower end of the connecting sleeve, and a damping pad is provided at the rotatable connection between the rotating ring and the connecting sleeve.

The side walls of the multiple fixed plates are provided with semi-circular blocks that cooperate with the push blocks.

[0010] Preferably, the connecting pipe is provided with a positioning strip, and the upper end of the punch body is provided with a positioning groove that cooperates with the positioning strip. Both the positioning groove and the positioning strip are square.

[0011] Preferably, the fixing plate and the outer wall of the connecting pipe are elastically connected by two springs, and the two springs are respectively sleeved on the outer walls of the two through rods.

[0012] The beneficial effects of this utility model are:

[0013] 1. By having multiple connecting strips extend into multiple connecting grooves on the outer wall of the punch body, the punch body can be quickly installed, which also makes it easier for people to disassemble and replace the punch body later.

The upper ends of the multiple support rods 2 are provided with a top plate 3. A hydraulic cylinder 4 is installed through the top plate 3. The outer wall of the telescopic end of the hydraulic cylinder 4 is provided with a threaded area 5. A connecting sleeve 6 is threadedly connected to the threaded area 5. The threaded connection between the connecting sleeve 6 and the telescopic end of the hydraulic cylinder 4 facilitates the installation of the entire device and makes it easy for people to maintain and replace the device, providing a certain degree of convenience.

[0022] A punch body 11 is provided below the connecting sleeve 6, and a connecting pipe 9 is provided at the lower end of the connecting sleeve 6. A connecting mechanism for connecting the punch body 11 is provided inside the connecting pipe 9. The connecting mechanism includes multiple circumferentially arranged placement grooves 14 opened in the inner wall of the connecting pipe 9. Each of the multiple placement grooves 14 is provided with a connecting strip 15. Multiple circumferentially arranged connecting grooves 12 that cooperate with the connecting strips 15 are opened in the outer wall of the punch body 11. By allowing the multiple connecting strips 15 to extend into the multiple connecting grooves 12 in the outer wall of the punch body 11, the punch body 11 can be quickly installed, which also brings certain convenience to the disassembly and replacement of the punch body 11 in the future.

[0023] The outer wall of the connecting pipe 9 is provided with a driving mechanism for driving the connecting mechanism. The driving mechanism includes two symmetrically arranged through rods 16 that slide through the placement groove 14 and the outer wall of the connecting pipe 9. One end of the two through rods 16 located in the placement groove 14 is connected to the connecting strip 15, and the other end of the two through rods 16 is provided with a fixing plate 17.

[0024] The lower end of the connecting sleeve 6 is rotatably connected to a rotating ring 8.
