In recent years, the competition in the die-punching manufacturing industry in the world has become more and more fierce. The ability of enterprises to provide customers with personalized high-quality products with high efficiency and low consumption in the shortest possible time has become the competitiveness of enterprises. A sign of it. The mold is called the father of industry. The quality of the punch parts of the mold parts will directly affect the quality, output, cost, production of new products and the renewal of old products, the adjustment speed of the product structure of the enterprise and the market competitiveness. The economic situation puts higher and higher requirements on the quality of die fitting punches. So how can we improve the quality of the die punch more reasonably? In other words, how can we make the die punch produce high quality parts in a high precision, low cost and high efficiency condition for a longer time and more? This has become more and more the focus of attention. The quality of the die punch is not a simple topic, it includes the following aspects:
1. Quality of die punch: stability and conformity of product size, smoothness of punch surface, utilization of punch material, etc.; in the design of mold structure, as compact as possible, easy to operate, and ensure the punch of the die The parts have sufficient strength and rigidity; when the die punch structure allows, the corners of each surface of the die punch parts should be designed as rounded transitions as much as possible to avoid stress concentration; for concave molds, cavities and partial punches, type The core can be combined or pinned to eliminate stress concentration, the elongated punch or core, and appropriate protective measures should be taken in the structure; for the cold die, a device to prevent the blockage of the workpiece or waste (such as: bomb) Top pin, compressed air, etc.). At the same time, it is also necessary to consider how to reduce the impact on the quality of the die punch caused by the wear of the sliding fittings and the frequent impacting parts in long-term use.
2, the service life of the die punch: under the premise of ensuring the quality of the punch, the number of work cycles that the die punch can complete or the number of parts produced;
3. Maintenance and maintenance of the die punch: whether it is convenient to use, easy to demould, and the production auxiliary time is as short as possible;
