Many people also know that there will be some problems in stamping the mold after using for some time, then we will ask the repair mold master to help repair. Even the best things after repair are not new, and so, it is better to use it in the process of some of its maintenance, then what are the ways? Xiaobian today we support a few strokes stamping die maintenance methods.
Stamping die maintenance methods:
1, punching die operation should be strictly controlled punch into the die elongation, so as to avoid wear and tear. Stamping dies used for some time, the convex and concave die edge will inevitably wear and wear groove marks. At this time we can repair the mold in advance, can reduce the friction, to prevent the cracks caused by wear and tear to avoid kink due to wear and tear, uneven die cavity gap caused by additional bending moment, which can extend the service life of stamping dies and reduce production cost.
2, should be used to lower the tensile speed of the drawing machine, easy to be stretched metal flow, reduce friction on the mold surface. Double-acting press tensile speed is slower, the force than ordinary punch smooth, uniform, enhance the life of tensile die.
3, between the drawing dies and the sheet material to be stretched must be coated with a suitable lubricant, try not to let the mold and the sheet material in direct contact to eliminate the adhesion conditions. Keep the surface clean and free of impurities, scale, rust, to avoid uneven wear premature wear mold. If the mold after use if the surface roughness worse, we need to promptly grinding and polishing.
4, cold extrusion mold work should also be reasonable lubrication, extrusion of black metal phosphating should be used plus lubrication. Cold extrusion process, mold temperature rise quickly, it should be regularly cooled. Winter low temperature, the best preheat the mold before use, to prevent the punch cold brittle fracture. Must establish a complete system of maintenance and repair, the designated person in a timely manner on the presses and mold adjustments, repair.
Stamping die on the maintenance methods and we explain to this, in addition to remind the mold in the storage and transportation process, to take anti-rust measures, the upper and lower die block should be limited between block protection.
