Many people also know that there will be some problems with the stamping die after using it for a period of time. At this time, we will ask the repair mold master to help repair it. No matter how good things are repaired, there will be no new ones. Instead of doing this, it is better to perform some maintenance on it during use. What are the methods? Today I will give you some tips on the maintenance methods of stamping dies.
Stamping die maintenance method:
1. When the punching die is operated, the extension of the punch into the die should be strictly controlled to avoid aggravated wear. After the stamping die is used for a period of time, the cutting edge of the convex and concave die will inevitably appear wear and wear groove marks. At this time, we can repair the mold in advance, which can reduce friction, prevent cracks caused by wear groove marks, and avoid additional bending moments caused by uneven wear and uneven gaps between dies. This can prolong the service life of stamping dies and reduce production. cost.
2. A drawing machine with a lower drawing speed should be used to facilitate the flow of the drawn metal material and reduce the friction on the mold surface. The drawing speed of the double-action press is slower, and the force is more stable and even than that of the ordinary punch, which improves the life of the drawing die.
3. Appropriate lubricant must be applied between the drawing die and the sheet to be stretched. Try not to let the mold and the sheet directly contact to eliminate the conditions of adhesion and seizure. The surface is kept smooth and free of impurities, oxide scale, and rust to avoid premature wear of the mold due to uneven force. If the surface roughness of the mold becomes worse after use, we need to grind and polish it in time.
4. The cold extrusion die should also be lubricated reasonably when working, and phosphating treatment and lubrication should be used when extruding ferrous metals. In the process of cold extrusion, the temperature of the mold rises quickly, so it should be cooled regularly. When the temperature is low in winter, it is best to preheat the mold before use to prevent the punch from being cold and brittle. A complete maintenance system must be established, and a dedicated person must be assigned to adjust and repair the press and mold in time.
The maintenance method of the stamping die will be explained to you. In addition, it is necessary to remind the mold to take anti-rust measures during storage and transportation, and to protect the upper and lower mold bases with limited blocks.
