Tell you the gantry punch press mould working parts plus the advantages and disadvantages of the surface quality for the mould's resistance to fracture capacity

     Punching machine manufacturer working parts plus the surface quality of the advantages and disadvantages of the mould sex, resistance to fracture ability and anti-adhesion ability has a close relationship, directly affecting the service life of the mould. The surface roughness value has a great influence on the life of the mould, if the surface roughness value is too big, it will produce stress concentration phenomenon when working, and it is easy to produce cracks between its peaks and valleys, and affect the die's not afraid of the cost, and it will also affect the surface of the workpiece is not afraid of the corrosion, and it directly affects the service life of the die and precision, for this reason, the following matters should be paid attention to:

    First, the use of grinding, grinding and polishing and other finishing and fine processing, to obtain a small surface roughness value, and improve the service life of the mould.
    Second, punch press processing should be prevented from leaving knife marks on the surface of the working parts of the mould. Intercalation, cracks, impact scars and other macro defects. The existence of these defects will cause stress concentration and become the root cause of fracture, resulting in early failure of the mould;

  Third, punch die work parts processing process need to prevent grinding burn parts surface phenomenon, should strictly control the grinding process prerequisites and process methods (such as grinding wheel hardness, particle size, coolant, feed and other parameters); manufacture of stamping die materials such as steel, cemented carbide, steel junction cemented carbide, zinc-based alloys, low-melting-point alloys, aluminium bronze, polymer materials, and so on. At present, the vast majority of the materials used in the manufacture of stamping dies are mainly steel, and the commonly used types of mould working part materials are: carbon tool steel, low alloy tool steel, high carbon and high chromium or chromium tool steel, medium carbon alloy steel, steel, steel, steel, steel, and cemented carbide, steel junction cemented carbide, and so on.
