Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Depend on figure 2 It can be seen from the schematic diagram of the structure of the pin of the present invention that the end face of the pin shank 2 has a radial positioning groove 4 punched out by the die, instead of the artificial punching hole in the prior art.
[0029] Depend on Figure 3 ~ Figure 5 As can be seen from the structural schematic diagram of the positioning groove processing mold for processing radial oblong holes of the present invention, it includes a lower mold assembly, an upper mold assembly, a punch 21, a locking mechanism and a guide mechanism. The lower mold assembly is installed on the workbench, one end of the guide mechanism is fixedly connected with the lower mold assembly, and the other end is slidably connected with the upper mold assembly. The number of pins 18 to be processed at one time is...
