Application and function of compression spring in sales market

With the development trend of the application technology of the special-shaped spring, a large number of regulations on the raw materials of the special-shaped spring are put forward. The key is to improve fatigue life and anti relaxation performance under high ground stress; the second is to provide corrosion resistance, non-magnetic, conductivity, wear resistance, temperature resistance and other aspects according to different main uses. Therefore, in addition to the development and design of high-quality varieties of spring machine price, we have achieved favorable results in the aspects of strict control of composition, reduction of non-metallic materials, and improvement of surface quality and specification precision.

(1) In order to improve the quality of special-shaped spring steel, the industrial production is relatively developed. In our country, the refining technology outside the furnace, steel rolling process, new cold rolling and on-line automatic identification and control system are generally adopted.

In order to ensure the composition of the steel, reduce the content of the vapor body of the automatic steel belt blanking machine and various nonmetallic materials, adopt the coiling equipment price, large space heating furnace or coke oven smelting, adopt the ladle refining outside the furnace, reduce the oxygen content (molar mass) to (0.0021 ~ 0.0010)%, produce ultra pure steel, and greatly improve the design scheme and work of special-shaped spring Medium in-situ stress.

The rolling process has been adopted in the production of special-shaped spring steel. Steel rolling can reduce shrinkage porosity, reduce secondary air oxidation and improve surface carburization according to electromagnetic induction mixing and ultra-low temperature forging, so that the mechanism and performance are stable and even.

The precision and surface quality of stainless steel plate can be improved by using split continuous extruder. In addition, the stainless steel plate can be symmetrical along the long and short microscope mechanism. In the whole process of cold rolling, in order to ensure the surface quality of goods, automatic identification and operation on line are adopted. In order to suit the production and manufacture of special-shaped spring galvanized flat steel with variable cross-section, a new cold-rolled forming technology of austenitic stainless steel was developed and designed, that is, the steel was heated to the austenitic stainless steel area and then quenched to the metastable austenitic stainless steel area to carry out plastic deformation processing and hot processing. This kind of processing technology can not only reduce the plastic deformation of steel, but also improve the compressive strength. In addition, the properties of special-shaped spring steel can be improved by quenching and tempering treatment and surface hardening after rolling.

(2) The development trend of carbon steel the key function of aluminum alloy element is to improve the structural mechanical properties, improve the processing performance and grant some unique properties. SiCr steel has been used in cylinder and suspension system. Si is an element of stress relaxation resistant aluminum alloy. Adding V and Mo to SiCr steel can produce sicrv and sicrmo steel, which can improve fatigue life and anti relaxation performance. In addition, the anti relaxation performance of SiCr drawing stainless steel wire in automatic steel strip crimping machine is better than that of piano stainless steel wire and carbon special-shaped spring stainless steel wire for key main use. With the high-speed practical application of diesel engine, Ti aluminum alloy with good anti flutter performance, light quality and small elastic die has been widely used, and its compressive strength reaches 2000mPa.
