Production Technology Of Hot Coil Spring

- Jul 14, 2017 -



Hot Coil Spring is also known as large spring, because this spring general diameter is very large, hot coil spring line diameter reached 16-200mm, the production process using hot roll process. The giant spring is easy to distort after heating, and the elasticity is small, after the molding needs quenching and tempering treatment. Coil spring is used in national defense, marine, aerospace, railway, nuclear power, wind power, thermal, engineering machinery, mining machinery, construction machinery, elevators, etc., supporting or replacement of steel mills and domestic power plants and other equipment on the spring.

Hot coil spring is mainly used for large-scale spring roll, easy to distort after heating, less elasticity, after the formation of quenching and tempering treatment.

Coil spring directly with the spring steel wire winding, back to a larger elasticity, Hot Coiling Spring winding tools need to consider springback compensation, roll into direct tempering treatment.

The main production process is different, taking the compression spring as an example:

Spring is a mechanical part that uses elasticity to work. The parts made of elastic materials are deformed under external forces, and then the original condition is removed after the external force. Also "Spring". Hot coil Spring (large spring) shape for right and left, cylindrical pull (pressure) force spring, torsion spring, Hot Coiling Spring as well as cone, middle convex, concave-shaped spring, etc.

Although the spring industry is a small industry throughout the manufacturing sector, its role is absolutely not underestimated. The country's industrial manufacturing, automotive industry to speed up the development, and as the basic parts, parts of the spring industry needs a more advanced development period, to adapt to the country's rapid development of the entire industry.

Now let's talk about the use of hot coil springs in the dust remover:

Dust Remover has advanced technology and stable operation. Off-line pulse bag filter control can be advanced programmable controller, with differential pressure, timing, manual three control mode, the off-line valve, pulse valve, ash relief valve, etc. to achieve a comprehensive system control. Hot Coiling Spring The design of reasonable inlet flow pipe and ash bucket diversion technology can solve the phenomenon of uneven airflow in every compartment of general bag duster. The upper end of the bag adopts hot coil spring expansion ring type, sealed well, repair replacement bag cage standard length of 6m, also can grow meters.

Spring is not only used in industrial production, and in the commodity industry and hardware industry, including lighters, toys, locks, door hinges, fitness, mattresses, sofas and so on, in terms of the number of cylinders, the largest demand for Bai, in the future, Hot Coiling Spring the market demand will be 7%~10% annual growth rate OH.
