Furthermore, the sliding block is limited by a cylindrical pin arranged on the sliding groove.

Compared with the prior art, the die has the main advantages that:

1. the bending and flattening process is integrated with one-step forming, so that the production efficiency is improved; 2, the positioning error is reduced by converting the two times of positioning into one time of positioning, and the product percent of pass is increased; and 3, the die is accurately positioned by adopting the design principle of a guide pillar and a guide sleeve, so that the die calibration time is reduced. Due to the requirement of product design, most parts of pin holes need to be bent according to a certain rule and flattened according to a certain rule when the pin hole type parts of the connector are machined, and two processes can be machined at one time through the die structure.
