Changzhou flat washer manufacturer, selection and processing technology of flat washer + daily production capacity of 3 million punching the next day

The Changzhou flat washer manufacturer said that it is impossible to make the bearing surfaces of bolts, screws, and nuts large in threaded fasteners (limited by materials and processes), in order to reduce the compressive stress of the pressure-bearing surface and protect the connection The surface of the piece uses a washer. The following Xiaoshuo will take you to understand the material selection and processing technology of flat washers: 　　 Flat washer material selection: 　　 Flat washers should be made of hot-rolled steel plates, hot-rolled and pickled steel plates or cold-rolled steel plates, or used bar or tube cutting And rolling, forging and other processing methods to manufacture. The specific processing method is determined by the manufacturer's choice.　　 Flat washers without mechanical performance requirements are generally made of corner materials, such as Q235A. When the hardness is required but not high, thicker plates can be used to calender to achieve the required hardness. Spring washers and other anti-loosening washers are generally made of 65Mn70# or S50CM-S70CM, and they must be heat treated (quenched + tempered).　　 Flat washer processing technology: 　　 Flat washer processing technology has two main types, one is deburring treatment, the other is surface protection treatment; 　　 deburring treatment, the gasket should be polished, vibrated or other methods to remove burrs and flash.
