Blue and white zinc flat washers, how to maintain the quality of the washer mold + 20000 sets of mold production experience
Blue and white zinc flat washers. Regarding the molds of flat washers, whether in the design and production, or in the initial processing of the mold, including the actual production of the assembly, we need our careful care to ensure the stability and stability of the flat washer mold. If the quality is qualified, Xiaoshuo will work with you to understand: 1. During operation, the extension of the punch into the female mold should be strictly controlled to avoid increased wear. After the flat gasket mold is used for a period of time, the edge of the convex and female molds will appear. At this time, we can repair the mold in advance to reduce the friction, prevent the cracks caused by the wear groove, and avoid the additional bending moment caused by the uneven gap between the concave mold and the convex after abrasion. At low temperatures in winter, preheat the flat washer mold before use to prevent the punch from being cold and brittle. 2. Contact surface In order to avoid premature wear of the flat washer mold due to uneven force, the surface must be kept clean and free of impurities, oxide scale and rust. If the surface roughness is deteriorated, we need to grind and polish it in time. 3. Increase lubrication during working hours. Phosphate treatment and lubrication should be used when extruding ferrous metals. In the cold extrusion process, the temperature of the flat gasket mold rises relatively quickly, so it is necessary to cool down regularly. Hardware, 15 years of focus on blue and white zinc flat washers, 5,000 square meters production workshop, 3 million punching production capacity per day, imported and national standard raw materials, 16 quality inspection layers strictly controlled, hundreds of precision processing production equipment, flat washers production The accuracy can reach 0.01mm. It can quickly solve the problem of customizing time for flat washers, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
