Embodiment Construction

[0016] The preparation method of safety belt steel belt provided by the invention comprises the following steps:

[0017] Pickling: Pickling the purchased steel strips.

[0018] Specifically, this step further includes: shelling to loosen the scale on the surface of the steel strip; putting the steel strip into an acid tank to make it react with hydrochloric acid, the concentration of the acid solution is between 15 degrees and 25 degrees, and the temperature of the acid tank is 30 degrees to 50 degrees; flush water on the surface of the steel strip to wash off the residual hydrochloric acid on the surface of the steel strip; enter the brushing machine to brush off the residue after the reaction on the surface of the steel strip; enter the neutralization tank to protect the surface of the steel strip from rust , the pH of the neutralization pool is between 6 and 8; on the coiler.

[0019] Slitting: Slitting the pickled steel strip on a slitting machine. The width of each ste...

Abstract

The invention relates to a fabrication method of a steel belt for a safety belt. The method comprises the following steps of pickling, longitudinal cutting, polishing, quenching, rolling, striping, and side pressing, wherein in the pickling step, the steel belt is pickled; in the longitudinal cutting step, the pickled steel belt is longitudinally cut; in the polishing step, the longitudinally cut steel belt is polished; in the quenching step, the polished steel belt is quenched; in the rolling step, the quenched steel belt is rolled; in the striping step, the rolled steel belt is striped, that is the rolled steel belt is longitudinally divided into a plurality of steel belts with the width equal to that of a safety belt spring; and in the side pressing step, the divided steel belts are subjected to the side pressing after or during the striping, and burrs on the edges of the steel belts are removed. Compared with the original technology, the fabrication method of the steel belt for the safety belt saves the step of annealing for many times, can save the annealing cost, simplifies the technology greatly, and shortens the production cycle.

Description

technical field [0001] The invention relates to the field of steel processing, in particular to a method for preparing a steel belt for a safety belt. Background technique [0002] The springs of seat belts are usually made of steel strips, which require a long service life. In the prior art, when producing steel strips for safety belts, the process is generally: purchase—>slitting—>pickling—>rolling—>annealing—>rolling—>rolling—>annealing—>rolling—>rolling Manufacturing—>Annealing—>Rolling—>Rolling—>Slitting—>Quenching—>Polishing—>Scraping—>Packaging. The process is very complicated, requires multiple annealing and rolling, the production cycle is long, the cost is high, and the hardness of the produced steel strips is different, resulting in unstable product quality. Therefore, how to develop a method for preparing a safety belt steel belt with high production efficiency, low cost and stable product quality has become a ...
