High strength shaped spring steel wire is used to make the washing machine with spring, locks with reset spring spring memory ark or door of important materials. This kind of product with high precision (+ / - 0.01 mm), high tensile strength (2000 mpa) or higher and cleaning rod stability. Domestic use of this kind of material is mainly imported from Germany, South Korea, Japan, the domestic independent research and development of materials in the shape, size, tolerance, etc have bigger difference, and it has low yield.

Production method of this kind of material is mainly divided into the die drawing, rolling, roll, rolling die drawing compound, rolling roll, composite, etc. The process is characterized by:

Rafa benitez.

Advantage is the product shape precision, small size tolerance; Defect is molding difficult, full of sharp corners owe and rounded corners, irregular surface easy cut, production cycle is long, complicated interface is difficult to produce.

2, the method of rolling

Mainly to solve the special steel wire in the generous than less than 4, especially the flat wire and trapezoid silk.

3, roller rafa

Advantage is that the wire passes deformation rate is large, sharp corners, shape accuracy, can produce complex section steel wire; Defect is wire dimension precision is not easy to control.

4, rolling - die drawing complex legal

Passes deformation ratio of big, to produce generous is large, complex shape, close to a kind of method to produce the low intensity of different spring wire, but if the production by this method has high precision (+ / - 0.01 mm), high tensile strength (2000 mpa) or higher, and the stability of the cleaning rod shaped spring steel wire, high strength due to the tensile strength of steel wire is higher, the end product of flatness is difficult to control.

5, rolling roll la complex legal

Optimization of production process for each, selecting the best feeding size, can produce a strength of 2000 mpa or shaped spring steel wire. Main process control points: round wire drawing the mechanical properties of the final products, in the process of rolling into the spread, pull the rounded and the deformation rate, finished product size precision of the spring steel wire.

Several process, rolling roll la complex legal suitable for production of high strength spring steel wire alien, in the industry is worth promoting.
