the cathode wire to be processed passes through the discharge tooth processing unit and the discharge tooth removing unit in a manual mode and is sent into the driving mechanism, then the press is started, the tooth forming upper die is driven to move through the sliding block, the cathode wire entering the tooth forming die is punched and cut, the discharge tooth is manufactured, the cathode wire for manufacturing the discharge tooth is discharged from the tooth forming die and enters the tooth removing die of the discharge tooth removing unit, when the sliding block moves, the cross rod drives the stud to move, the stud moves downwards to press the movable plate to move downwards, the movable plate compresses the elastic piece, the discharge tooth at the end part of the cathode wire is punched and cut through the cooperation of the tooth removing upper die and the tooth removing lower die, after the discharge tooth at one end is cut, the handle is rotated, the cylinder moves away from the lower end of the stud, and the discharge tooth removing unit does not participate in working, and when the discharge tooth at the other end of the cathode wire is required to be processed, the cylinder is rotated to the position below the stud again.
The cathode ray machining mechanism has the following advantages:
1. the discharge tooth machining unit and the discharge tooth removing unit are integrated to the workbench of the press, so that the functions of synchronously machining the discharge tooth in the middle of the cathode wire and removing the discharge tooth at the end part of the cathode wire are realized, the machining procedures are reduced, and the efficiency is improved.
2. By integrating the discharge tooth machining unit, the discharge tooth removing unit and the cathode wire moving driving mechanism to the workbench of the press machine, the occupied area of equipment required for machining the cathode wire is reduced.
3. The production cost for processing the cathode line is reduced.
