The production line can also be connected with multiple rear punching presses, the number of the rear punching presses can also be flexibly adjusted according to the production process needs, and the stretching, shaping, edge cutting and other processes can be realized, and the position of the body of the rear punching press is adjustable, can move along the direction of the production line, so that the distance between the adjacent presses and the length of the part are in an integer multiple relationship, to meet the punching needs of parts of different lengths.

[0021] The plate adjusting device can make the production line adapt to the plate with the width in the range of 0 to 450 mm and accurately guide the plate. The length detection device arranged behind the plate adjusting device can detect the length and conveying speed of the plate and feed back to the pre-punching press and the post-punching press, so that the pressing speed of the press is matched with the conveying speed of the plate.

[0022] The material guiding and leveling device can guide and level the plate after pre-pressing.
