Hot Spring Is Widely Used In Railway And Other Fields

- Oct 26, 2017 -

Hot spring is a large spring, hot roll refers to the production process, large spring roll process we most commonly used is the hot coil spring, and its characteristics are mainly reflected in the heat easily distorted after forming, back Less elastic, after quenching after tempering treatment. Hot spring in the course of the main play to bear the role of load, and it can bear the number of load it? This depends on the outer raceway angle, Hot Coiling Spring the greater the angle the greater the carrying capacity. There are conical inner and outer ring raceway, tapered roller arranged between the two. The projection lines of all conical surfaces converge at the same point on the spring axis. And its load situation also determines its use in the industry. We purchase the time to purchase high-quality products, so that its load is more assured. Hot roll spring general implementation of the national standard, Hot Coiling Spring the surface to do spray, painting, plating, Dacromet and other treatment. Hot spring is widely used in defense, marine, aerospace, railway, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, elevators and other fields.

Hot roll spring material: alloy spring steel: 60Si2MnA, 50CrVA, 4Cr13, 60Si2CrA, load capacity: 500N-1 million N.

Hot roll spring application: hot coil spring, also known as large spring, Hot Coiling Spring because the spring diameter is very large, hot coil spring diameter of 16-200mm, the production process using hot roll process. Giant spring is easy to twist after heating forming, less resilience, after quenching and tempering after molding. Spring used in national defense, marine, aerospace, railway, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, elevators, supporting or replacement of steel and domestic power plants and other equipment on the hot coil spring.

Hot coil spring is mainly used for large spring roll, Hot Coiling Spring easy to twist after heating forming, less resilience, after quenching after tempering treatment.

Hot roll spring Typical process: blanking --- end processing (rolling flat or forging flat) --- heating --- coil spring --- quenching --- tempering --- grinding end face --- compression - - (load test) - shot peening (cleaning) --- painting.

The type of hot coil spring is 30000 and the hot coil spring is a separate spring. In general, especially in the GB / T307.1-94 "rolling spring centripetal spring tolerance" in the size range of the hot coil between the outer ring and the inner components is 100% can be used interchangeably. Hot Coiling Spring The angle of the outer ring and the size of the outer raceway diameter are the same as those of the external dimensions. It is not allowed to change at design and manufacturing. So that the outer ring and the inner assembly of the hot coil spring can be universally interchangeable around the world.

The hot coil spring is mainly used for radial and axial joint loads with radial load. Hot Coiling Spring Compared with the angular contact ball spring, carrying capacity, low speed limit. The hot coil spring can withstand the axial load in one direction and can limit the axial displacement of the shaft or housing in one direction.
