The influence of press precision on precision hardware

In the processing of precision hardware, there are fine, efficient, and long-lasting molds. Without high-precision presses and high-quality precision hardware materials, precise and efficient stamping cannot be achieved; the precision and rigidity of the precision hardware processing equipment press It has a great influence on the life of the mold, and also has a great influence on the precision hardware.
1. The accuracy of a press is usually expressed by its static and rigidity. The static accuracy can be divided into special grade, level 1, level 2, and level 3. The rigidity of the press is also an important element, which is the strength of the press;

2. The precision hardware processing equipment press must be deformed while receiving the load. The capacity of the press must be determined according to the amount of deformation. The fine blanking process must be performed under 50% of the machining capacity of the press, if it exceeds its capacity. At 80%, the uniformity of the mold gap cannot be guaranteed, the high-precision press can extend the life of the mold, and the quality of the precision hardware produced is good;

3. In the zigzag forming process, the static accuracy of the precision hardware processing equipment press has little effect on the part, but the rigidity of the press has a certain influence on the part;
4. The rigidity of the press has a greater impact on the quality of the parts, but the rigidity is low, and it can be compensated by the method that the processing pressure is lower than the nominal pressure. However, the accuracy of the press is not high, which has a direct impact on the life of the mold. High-speed active presses for high-precision parts, special punching presses, cold extrusion presses, embossing toggle presses, hot forging presses, etc. should all be designed with high rigidity.
