Wuhan modern washers, retaining rings, pins and rivets, tools
Washers and retaining rings are generally used directly without heat treatment. For high requirements, medium carbon steel or medium carbon alloy can be used after tempering and elastic washers (including spring washers, toothed or saw-shaped tight pads, saddle-shaped or wave-shaped elastic washers) and elastic retaining rings are mostly spring Steel manufacturing. The heat treatment process is similar to the spring heat treatment. The spring washer is made of 65Mn, 70, 60Si2Mn steel, and the surface hardness after fire + medium temperature tempering is 2-0HRC. The toothed and saw-shaped lock washers are made of 65Mn copper. The surface hardness after melting and tempering is 40HRC, and the fruit is made of 6M. The surface hardness after fire and middle temperature is EOHRC. The property is 63Mn and 6Ma steel. Manufacture, surface temperature after fire and middle temperature,
Spring washers are made of trapezoidal spring steel wire. Tooth-shaped or saw-shaped lock washers, saddle-shaped or wave elastic washers and elastic retaining rings are all stamped and formed from spring steel plates. The material supply state requires chemical annealing to ensure fine-grained spherical carbide weaving. www.handern.com plastic building template

There are many types of pins, and depending on the conditions of use, the material selection and heat treatment requirements are also different. When made of carbon steel such as 35 and 45, the hardness after quenching and tempering (that is, quenching and tempering) is 28-HRC (35 steel); 38-46HRC (45 steel), and the surface treatment (oxidation or zinc passivation) Chemical). When alloy steel such as 30 Crmnsia is used, the hardness is 35RC after quenching and tempering (that is, quenching and tempering), and surface treatment (oxidation or galvanizing passivation). Fruit copper and copper alloys such as H62, HPH59-1, QS3-1, etc., are mainly used in the atmosphere or sea water. Pins under conditions with little manpower are used under high temperature or corrosion resistance, according to The specific working conditions are made of stainless steel such as 1Crn3, 2Cl3Gha, 1Cnl8Ni9T. www.handern.com plastic building template
3. Wuhan Modern Rivet www.handern.com plastic construction template
The materials used for rivets are mainly carbon steel, special steel, copper and copper alloys. For plain steel such as Q215, Q235, ML3, ML2, 10, 15, ML10, ML20, etc., the raw materials should be annealed. After the production, due to cold work hardening, in order to facilitate riveting, recrystallization annealing should be carried out. Surface treatment (passivation by galvanizing) or not according to requirements. Cryogenic steels such as 0Cr18Ni9 and 1Crl8Nip should be quenched and quenched (solid solution treatment) to achieve the purpose of softening. www.handern.com plastic construction template.
4. Wuhan Modern Tools
The working conditions of the tool are more complicated. Hand tools are low-speed cutting, and friction is often the main tool during processing, and there is often a large impact; machine tools usually have a high cutting speed, which generates a lot of cutting heat, and sometimes the cutting edge softens. In this regard, metal cutting tools should first have high hardness and wear resistance. At the same time, cutting tools must also have sufficient toughness. Red hardness is also an important performance of cutting tools. Especially high-speed cutting tools and tools for cutting difficult-to-machine materials. In addition, some cutting tools have special requirements on the manufacturability of the materials. For example, the material of the thermoforming drill bit must have high thermoplasticity, and the material such as gear hobs and shaving cutters must have good grindability. The failure of cutting tools is mainly due to wear, chipping, breaking, breaking or processing of workpieces that do not meet the technical requirements and other reasons.
There are two main types of tool steel: ordinary tool steel and high-speed tool steel. www.handern.com plastic construction template.
