Embodiment Construction

[0024] In the invention, the pre-cut stainless steel strip coil material is uncoiled, and then leveled to ensure that the surface of the steel strip is straight, and then punched on the surface of the steel strip, and then continuously sent to the special cold-bending forming equipment for gradual cooling. Bending into shape, and finally cut to length according to the actual required length. The specific method is as follows:

[0025] A method for manufacturing a stainless steel strip for a steel-aluminum composite contact rail of the present invention, comprising the following steps:

[0026] 1) First unroll the stainless steel coil installed on the uncoiler; the uncoiler is composed of a welding frame, a tensioning shaft system, a motor reducer drive, a binder head and a brake.

[0027] 2) Use the lead leveling machine to level the unrolled steel coil, so that the steel coil becomes a flat steel strip; set the feeding rollers before and after the lead leveler to make the st...

Description

1. Technical field [0001] The invention relates to a steel-aluminum composite contact rail for urban rail transit, in particular to a method for manufacturing a stainless steel strip for a steel-aluminum composite contact rail. 2. Background technology [0002] With the rapid development of rail transit, the quality requirements for rail transit steel-aluminum composite contact rail are getting higher and higher. The currently used contact rail for power supply usually consists of a substrate and a brush surface. The brush surface is connected to the substrate, and the brush surface is made of wear-resistant materials. There are stainless steel strips running along the length of the brush face, wherein each steel strip together with a longitudinal elongate side of the brush face part forms a depression which is at least partially filled with the material of the base body. [0003] As an important part of the steel-aluminum composite contact rail, the quality of the stainles...
