Description

Stamping and slitting die for surgical knife head after milling Technical Field The application relates to the technical field of punching and slitting devices, in particular to a punching and slitting die for a surgical knife head after milling. Background The stamping and cutting technology after milling the scalpel head is a processing technology in the field of medical instruments, and is mainly used for improving the precision and quality of a scalpel blade so as to meet the requirements of minimally invasive surgery. Minimally invasive surgery is popular to patients because of small trauma, light pain and quick recovery, but has high requirements on the precision of surgical equipment. In addition, because of the small size of the surgical blade, it is generally formed in a plurality of batch processes. After milling the surgical heads, it is necessary to slit a plurality of surgical heads. For this reason, prior art provides a vapour-pressure type shearing sword and cutting device, and it includes blade holder subassembly and tool bit subassembly, and the blade holder subassembly includes stroke adjustment unit and blade holder base member, and stroke adjustment unit includes the connecting rod, and the connecting rod runs through the blade holder base member and can be dismantled with the tool bit subassembly and be connected, still includes the sleeve, and the sleeve cup joints on the connecting rod, and sleeve lateral surface and the interior wall interference fit of blade holder base member.
