The Influence of Structural Design on Die Safety
Die safety, in general, is related to multiple aspects of the die structure, such as design, material selection, machining precision, welding, assembly accuracy and so on. In order to ensure the safe operation of stamping dies, the most important thing is to pay attention to the structural design. The structural design has a great influence on the safety of the die.
First, on the one hand, the design of the die structure is mainly to ensure that the stepped distance of the pressing and shearing are consistent and reasonable, which not only ensures the verticality of the sheet metal during stamping, but also reduces the deformation of the die. Improper design of the structure will not only reduce the stamping accuracy of the workpiece, but also increase the possibility of the die misalignment and plate becoming soft.
On the other hand, the structure should also be designed to optimize the force and stress problems in the press die system. Stress should be evenly distributed throughout the press and die system to the greatest extent, and damage caused by excessive local stress should be avoided. In addition, some measures should be taken to increase the stiffness of the die and reduce deformation, such as through increased size, thickening of wall parts, adequate reinforcements and appropriate changes in shape, so as to ensure the accuracy and safety of the die.
Finally, to ensure the safety of the press die, attention should be paid to the selection of materials and heat treatment methods. It is generally believed that the materials of the press die should be selected according to its working conditions, the hardness of the core should be relatively high, and the hardness of the working surface should be slightly lower. In addition, proper heat treatment can also effectively improve the anti-fatigue and wear resistance of the die.
In conclusion, the structural design of the die has a great influence on the safety of the press die. Only by optimizing the structure design and material selection, and paying attention to the heat treatment method, can the stamping accuracy and service life of the die be ensured, so as to ensure the safety of the die.
