To raise the durability of metal stamping mould several trick to tell everybody

Metal stamping die in the process of production will often wear, so how to improve the durability of stamping die? Cold stamping die is essential in the process of metal stamping parts production process equipment, the quality of the mold to improve the quality of the products and prolong the life of products, improve production efficiency has a decisive role. However, due to the metal stamping mold in the process of production have lost their jobs due to often wear size, cause it's hard to meet the production requirements. Therefore, improve the durability of stamping die is critical, today the author compiled a few useful solutions for all learning together to explore: improving the design of stamping die cold stamping mould design is reasonable is to improve the durability of progressive metal stamping tools. To design a stamping die as a result, the adverse conditions to take effective measures in response to the product forming, in order to improve the durability of progressive metal stamping tools, such as the life of the stamping die design holes tend to show on the rush hole punch. For metal stamping mold, the design should make small punch when try to shorten the length, in order to increase strength, at the same time, should also adopt the method of guide sleeve strengthening protection of small punch. In addition, in the stamping die design, should fully consider the die set, intensive, in the form of fixed methods and guidance form template, the determination of pressure center and the upper and lower rigidity etc. Especially for blanking die, selecting the clearance value have great effects on durability. , when the design of stamping die clearance should choose reasonable, its clearance values cannot be too small, otherwise it will affect the service life of the stamping die and durability. Practice has proved that under the condition of not affecting the quality of stamping parts, proper amplification clearance can greatly improve the durability of stamping die, sometimes even several times and times. Correct selection of different stamping die stamping die materials materials with different strength, toughness and wear resistance. Under certain conditions the use of advanced materials can make the durability for several times. Therefore, in order to improve the durability of progressive metal stamping tools must choose good material. 1) Thick steel plate, Typical cases for punching and shearing thickness 35 mm steel plate) , stainless steel plate, as well as non-ferrous metal plate stamping molding, typically is air conditioning wing piece mold, etc. 2) Tensile mold, stainless steel tensile mold. 3) Cold extrusion dies. Cold extrusion of 304 stainless steel, the thickness of 0. More than 5 mm, replacing DC53 materials such as, the effect is very good. 4) High dimensional stability requirements of large stamping templates. Reasonably for forging and heat treatment of stamping die parts in the choice of high quality stamping die at the same time, for the same material and different nature of the material requirements for the reasonable forging and heat treatment, is one of the main ways to improve the stamping tool durability. Quenching when, for example, if produce overheating when heated, will not only make the workpiece brittle is too big, and easy to cause deformation and cracking during cooling, lower the durability. So when manufacture stamping mould, heat treatment process must be reasonable. Reasonable arrangement of stamping mould manufacturing process and guarantee the accuracy of processing precision metal stamping mold had a great influence on durability of stamping die. As in blanking die due to the uneven assembly clearance, in under the action of shear force on the concave mould are always bad and affecting the service life of stamping die. At the same time, the stamping die surface is bright and clean spend low, will reduce the durability stamping die. , therefore, must be on the pitch size when processing, the assembly when the punch on the fixed plate supporting surface vertical, uniform and guide bush of stamping die spacing, guide post orientation precision grade given sufficient attention. Manufacture and assembly accuracy is higher and the working part of the surface roughness, the higher the grade, the higher durability of stamping die. Correct selection of press in order to improve the durability of stamping die, should choose press with high precision and high rigidity, and make the stamping tonnage outweigh the impact force of more than thirty percent. Normally, the use of the servo press can improve die life corresponding over several times or more. Rational use and maintenance of stamping mould in order to improve the stamping tool durability, the operator must be reasonable use and maintenance of stamping die, the stamping die should be regular maintenance, in order to prevent the stamping die to work in spite of illness. Above is to raise several commonly used methods of stamping die wear-resisting degree, improve the wear-resisting degree not only makes the meaning of stamping die service life increase, reduce the production cost of mold enterprise, more can guarantee the quality of manufactured products, improve production efficiency' Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
