Stamping mould material and heat treatment process of detailed
2015-03-24 9:25:22
 According to the survey, failure in all die factors, material and heat treatment of die accounted for about 70% of the proportion, became a major influence die life. Therefore, in the mold manufacture the whole process of design, selection and heat treatment process of die material is appropriate is particularly important.
Stamping die working parts material requirements, stamping die work to bear the impact, vibration, friction, high pressure and tensile, bend torsion load, work even at higher temperatures (such as cold extrusion), complex working environment, easy wear, fatigue, fracture, deformation phenomena. Therefore, on the die working parts material requirements than ordinary parts of high.
Because all kinds of stamping die working conditions are different, so the working parts of die material requirements are also different.
The 1 blanking die material requirements
For sheet metal stamping die working parts material requirements with abrasion resistance and high hardness, and the blanking die for thick plate in addition to request with compressive wear resistance, high yield point, in order to prevent mould breaking or chipping, bending strength also has higher fracture resistance, and toughness.
The 2 drawing die material requirements
Requirements of the mold work parts material has good adhesion (anti anti bite), strong toughness, hardness and wear resistance, certain high and cutting performance is better, and the heat treatment deformation is smaller.
3 cold extrusion die material requirements
Requirements of the mold work parts have the strength and hardness, high wear resistance high, broken in order to avoid the impact, also requires a certain toughness. Because the extrusion produces larger warming, so also has the resistance to thermal fatigue and thermal rigid.
The types and characteristics of stamping die materials
Manufacture of stamping die materials are steel, hard alloy, steel bonded hard alloy, zinc alloy, low melting point alloy, aluminum bronze, high polymer material and so on. At present, most of the stamping die manufacturing materials to steel based, species die components commonly used materials are: carbon tool steel, low alloy tool steel, high chromium or Gao Tan in chromium tool steel, medium carbon steel, high speed steel, steel substrate and hard alloy, steel bonded hard alloy and so on.
1 carbon tool steel
Carbon tool steel is more in the mold for T8A, T10A and so on, has the advantages of good processing performance, cheap price. But the hardenability and red hardness difference, heat treatment deformation, low bearing capacity.
2 low alloy tool steel
Low alloy tool steel is adding some alloy elements based on the carbon tool steel on the. Compared with the carbon tool steel, reduce the quenching deformation and cracking tendency, improves the hardenability of the steel, the wear resistance is good. Low alloy steel for the manufacture of mould are CrWMn, 9Mn2V, 7CrSiMnMoV (CH-1), 6CrNiSiMnMoV.
