Description

Technical Field

[0001] The utility model relates to the technical field of screw heading machines, in particular to a high-precision screw heading machine. Background Art

[0002] The main function of screws is to connect two workpieces together and play a role in tightening. The heading machine is a cold heading equipment and is the main equipment for forming the screw head. There are usually two multi-station processing methods adopted by traditional screw heading machines: one is the rapid swing of the punch to punch the workpieces at different stations, and the other is to use a punch pliers to move the workpiece from one station to another. The rapid swing of the punch is a reciprocating motion, and the useless work generated by the rapid reciprocating motion is much greater than that of the circular motion. Therefore, the reciprocating motion mechanism is easy to be damaged, the punch is also prone to failure, and the accuracy is difficult to control. It is difficult to adjust the punch pliers, especially for small workpieces, which are difficult to clamp and adjust. The hardness of the punch pliers is required to be high. If it is too hard, it is easy to damage the workpiece or the mold. If it is too soft, it is easy to damage itself. Eventually, due to the wear of the jaws, the workpiece cannot enter the mold correctly, resulting in stamping failure and damage to the mold.

[0003] In order to improve the processing efficiency, after searching, the Chinese patent with the announcement number CN204234921U in the prior art discloses a multi-station screw heading machine, including a slide mounted on a horizontal bed and capable of horizontal reciprocating motion, a plurality of punches with male dies are mounted on the slide in a circular arrangement, an intermittently rotating mold box is arranged at the position of the bed relative to the punch, the mold box is cylindrical, the end face of the cylinder is opposite to the punch, and a plurality of stations with female dies are arranged in a circular arrangement on the end face.
