Problems solved by technology
[0002] In the process of manufacturing alloy products, a stamping device is required. A punch is used in the stamping device. The punch punches the workpiece. The existing punch used for the stamping device is integrated. It is used for processing the workpiece. , the contact between the punch and the workpiece is prone to greater damage. Because the punch is integrated, its local damage will be scrapped as a whole, and the punch used in the stamping device generally uses alloy steel. The cost is relatively high, and once scrapped, it will be scrapped It will cause the increase of production cost and the waste of resources

The invention discloses a punch device with a changeable punch, which comprises a punch holder and the punch. A punch groove is arranged in the punch holder, positioning slots are arranged on the inner wall of the punch groove and respectively in the shape of labyrinth with three right-angles and extend from the end opening of the punch groove to the inside of the punch groove, the punch is provided with a cylindrical fastening block, the cylindrical fastening block is provided with positioning fasteners, and the punch is fixed into the punch groove by the aid of the positioning fasteners matched with the positioning slots in the punch holder. By the design of the labyrinth with three right-angles, the punch is changeable on the basis of the original punch structure, while effect of the punch cannot be affected during use, and accordingly the problem that the punch is discarded integrally after being damaged is solved well, cost and resources are saved and utilization rate of materials is increased.
Description
technical field [0001] The invention relates to a punch device, in particular to a punch device with replaceable heads. Background technique [0002] In the process of manufacturing alloy products, a stamping device is required. A punch is used in the stamping device. The punch punches the workpiece. The existing punch used for the stamping device is integrated. It is used for processing the workpiece. , the contact between the punch and the workpiece is prone to greater damage. Because the punch is integrated, its local damage will be scrapped as a whole, and the punch used in the stamping device generally uses alloy steel. The cost is relatively high, and once scrapped, it will be scrapped It will cause an increase in production costs and a waste of resources. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the object of the present invention is to propose a punch device with replaceable heads. [0004] The technical solut...
