[0002] The can body stretching machine is a device that uses a punch to stretch a metal cup in a mold to form a metal can body with a certain height. After forming, the metal can body needs to be removed from the punch and then transported to the next device or the next process by the can removal assembly. The function of the demoulding assembly is to remove the metal can body from the punch. The demoulding assembly mainly includes a demoulding ring, a demoulding rubber ring and a demoulding cover plate. The demoulding rubber ring is an important part and needs to be replaced frequently.

[0003] The prior art uses 8 evenly spaced screws to directly lock and fix the demoulding cover plate on the demoulding ring, so that the demoulding rubber ring is clamped between the demoulding ring and the demoulding cover plate. This locking method requires all 8 screws to be loosened when replacing the demoulding rubber ring, so that the demoulding cover plate can be removed and the demoulding rubber ring can be replaced. After replacing the demoulding rubber ring, the 8 screws need to be re-locked. This structure is relatively cumbersome during the disassembly and installation process.

[0004] Therefore, it is necessary to design a new locking method to reduce the time for replacing the demoulding rubber ring. Summary of the invention

[0005] The utility model aims to provide a rapid disassembly device for a demoulding cover plate of a can body stretching machine, so as to reduce the time for replacing a demoulding rubber ring.
