Dalian stamping Manufacturers of Stamping parts The common problems in the process of

At present, metal stamping parts are widely used in our life, with the development of science and technology, metal stamping parts processing technology is more and more mature, more or less, but there are still some problems. To everybody below the common problems and causes of the introduction of metal stamping processing. Concave or hollow material surface is abnormally protruding, uncoiling line foreign body (iron and dust) caused by mixing;

India: sliding caused by roller sliding occurs in a sudden stop or acceleration; roller printing: cleaning roller or roller feeding attachment caused by foreign bodies (with fixed pitch occurs), under normal circumstances can be printed on the sheet roller bodies can be removed; burr: punching or cutting edge angle in the process of incomplete stay more than the material, plate section parts burrs, in section as a benchmark, burr height is value= ".2" unitname= "mm" w:st= "on" style= "margin: 0px; padding: 0px; list-style: none;" above >0.2mm, occurs here will damage the mold and produce concave iron powder. Roll crushing might wrinkle wrinkle: edge guide roll scene uncoiling line could guide roller clearance hours on the mold to produce, because of the imbalance caused by the roll into the. We must have a reasonable value, the gap between punch and die fillet radius and machining precision in mold design. The design of bending die, we should take effective measures to reduce the springback, and minus the springback in the mold; design reasonable fillet, prevent bending crack. When drawing the blank holder to prevent wrinkling, and the pressure should be moderate; reduce drawing resistance with proper lubrication, to prevent mold adhesion or make the workpiece pulling.

There are a lot of defects in metal stamping parts, such as scratches, dents, cracks, burrs, oxidation and so on convex, we must pay attention to these details in the metal stamping processing, in order to bring greater benefits. The effect and advantages of titanium stamping mold, precision Stamping die Coated nano PVD coating surface can have a very low coefficient of friction, reducing machining force. The mold coated nano PVD coating after surface hardness can be increased by 5 to 10 times, can be precision stamping die coated nano PVD coating surface can have a very low coefficient of friction, reducing machining force. The mold coated nano PVD coating after surface hardness can be increased by 5 to 10 times, can significantly reduce surface wear, especially to obtain excellent surface quality for high precision machining. Cold stamping forming and drawing dies by the nano coating can significantly reduce the friction, reduce processing scratches and wear. It can increase the service life, greatly reducing the production cost.

The friction coefficient decreased, reducing machining force to improve the surface hardness, greatly prolongs the service life of the mould. To prevent galling, injury, improve product quality, save mould unloading, then die polishing troubles, improve efficiency. More metal forming in the production of abrasive wear, adhesive wear and various forms of surface damage. Department of science and technology into the nano coating to solve the above problems, we choose the suitable coating, can effectively solve the above problem. The coating has good lubricity, good effect is obtained in the metal forming industry.

With high hardness and high strength, hard coating can reach the hardness of traditional surface treatment can effectively protect the mold surface, high wear resistance. The hard coating has high hardness but also has good lubricity and low friction coefficient, excellent molding production parameters to obtain ideal life. Good lubrication. In metal forming, material in the mold flow caused by molding surface damage, good lubrication coating will reduce the work area bear wear
