Coach bolt hot extrusion forming equipment

Abstract

The invention relates to the field of coach bolt stamping forming, in particular to coach bolt hot extrusion forming equipment. The equipment comprises a stamping table, a stamping machine and a stamping die, the stamping die comprises a fixed die block and two movable die blocks, the two movable die blocks are symmetrically arranged at the top of the fixed die block, the symmetrical face of the two movable modules is the middle section of the fixed module, the two movable modules can relatively slide on the fixed module, the fixed module is further provided with a driving device used for driving the two movable modules to relatively slide, the stamping table is further provided with a supporting table used for supporting a coach bolt, and the supporting table is also provided with a lifting device for lifting the coach bolt. According to the equipment, through cooperation between the fixed die and the movable die, the coach bolt can be attached to the edge of the movable die after being punched and formed, the forming quality of the coachbolt is improved, and the situation that assembly is affected when the coach bolt is used is avoided.

Description

technical field [0001] The invention relates to the field of stamping and forming of square head bolts, in particular to hot extrusion forming equipment for square head bolts. Background technique [0002] Currently on the market, the head forming process of square head bolts mostly adopts upsetting the round head first, and then cutting off the excess material. However, this forming process has the following defects: the material loss is large, and due to the need to cut off the , so the blank before cutting needs a lot of sufficient material to cut off, resulting in high cost and large burrs on the head support surface. Due to the cutting process, the burrs on the head support surface are large, which affects assembly. Smooth, large roughness, punching will produce tear strips, which will affect the appearance quality. [0003] At present, for the processing and forming process of square head bolts, since the ends of the square head bolts are square head-shaped, it is nec...
