Problems solved by technology

The disadvantages of this kind of equipment are: due to the high requirements on bending technology and drilling precision during processing, the process is complicated, and it cannot be formed at one time, so the product quality and dimensional accuracy are poor; and the efficiency is very low.
So far, there is no mature special equipment for the processing of stainless steel strips for steel-aluminum composite contact rails, and general-purpose equipment cannot meet the requirements for mass production of steel-aluminum composite contact rails

Embodiment Construction

[0018] A special equipment for forming stainless steel strips for steel-aluminum composite contact rails according to the present invention, including an uncoiler 1, a material leveling machine 2, a shearing butt welding platform 3, a servo feeder 4, a hydraulic punching machine 5, a rolling press Forming unit 6, cut-to-length machine 7.

[0019] The uncoiler 1 is used to support the unwinding of the stainless steel coil, and the uncoiler 1 is arranged on the front side of the leading material leveling machine 2 . The uncoiler is composed of a welding frame, a tensioning shaft system, a motor reducer drive, a binder head and a brake.

[0020] The material leveling machine 2 makes the stainless steel coil unroll smoothly and flattens the unfolded steel coil; the feeding rollers are set before and after the material leveling machine 2, the motor is decelerated and driven by frequency conversion, and the front roller guides the plate. The head of the sheet is released and the sh...

Abstract

An apparatus for forming the stainless steel band used for the composite steel-aluminum conductor rail is composed of decoiler, guiding-leveling machine, shearing-butt welding machine, servo feeder, punch machine, rolling set and sizing-cutting off machine.

Description

1. Technical field [0001] The invention relates to a production equipment for stainless steel strips, in particular to a special equipment for forming steel strips for rail transit steel-aluminum composite contact rails. 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 stainless steel...
