[0032] Working principle: When in use, the device can be first carried to a designated position and powered on, and then the material is placed on the top of the cold heading groove 19. The hydraulic cylinder 12 can drive the mounting plate 10 and the components above it to move downward, facilitating the cooperation between the cold heading block 9 and the cold heading groove 19 to perform the cold heading and pressurizing and forming work on the material;

[0033] At the same time, when the mounting plate 10 moves downward, the pressing block 8 can first contact the U-shaped pressing plate 2, and then the U-shaped pressing plate 2 is pushed by the pressing block 8 to drive the connecting rod 5 and the top plate 6 to move to a designated position inside the cold heading groove 19 to realize the stretching operation of the spring one 4. The later cold heading and forming work of the object can be conveniently realized through the movement and accommodation of the top plate 6;

[0034] After the cold heading is completed, when the hydraulic cylinder 12 drives the mounting plate 10 and the components above it to move upward to release the resistance to the U-shaped pressing plate 2, the elastic restoring force of the spring one 4 can drive the U-shaped pressing plate 2, the connecting rod 5 and the top plate 6 to return to their original positions. The ejection operation of the material inside the cold heading groove 19 can be realized through the restoration of the top plate 6, so as to improve the convenience and flexibility of later material taking, and there is no need for the operator to use other material taking tools, reducing the working steps of the operator and improving the material taking efficiency;

[0035] When the operator realizes the replacement operation of the cold heading block 9 and the cold heading groove 19 in the later stage, the push plate 17 can be directly pushed to move inside the U-shaped fixed card slot 11. Then, through the guiding inclined plane design of the push plate 17 and the push block 16, the push plate 17 can directly push the push block 16 to move and expand inside the U-shaped fixed card slot 11. Then, the push block 16 drives the L-shaped fixed rod 14 to move out of the fixed slot 15 to release the fixation of the clamping block 18. At the same time, the compression operation of the second spring 13 can be realized through the movement of the L-shaped fixed rod 14. Furthermore, it is convenient for the operator to take out and replace the cold heading block 9 or the cold heading groove 19, without the operator having to perform multiple sets of screw-tightening operations, effectively improving the convenience and flexibility of the later disassembly and assembly of the device.
