Factory source Mash Tl2 Guardrail Cold Bending Machine - steel pipes thread rolling machine with three shaft – Yingyee

maximum pressure 250KN steel pipes Thread Rolling Machine with three shaft

Due to teeth of an internal roller brush wheel and an external roller brush wheel under the preset pressure of a spring, a steel pipe wall is bent and deformed and simultaneously is driven to rotate by the rotation of the internal roller brush wheel and the external roller brush wheel, the tube wall can generate heat due to the friction of the rotation line speed difference of the internal roller brush wheel and the external roller brush wheel, so that the strength of the material is lowered; the material can generate rebound fatigue due to continuous rolling brush of the internal roller brush wheel and the external roller brush wheel, so that along with gradual decreasing of the rebound deform performance of the tube wall material, the teeth of the roller brush wheel are gradually pressed into the tube wall under the preset pressure, the tube wall is molded and deformed according to the teeth of the internal roller brush wheel and the external roller brush wheel, so as to form cylinder tube threads or internal and external threads of a conic tube. The thread rolling machine has the characteristic that the molded thread is low in stress, so that the middle wall of the tube can be molded with threads, and the problem of stress corrosion of stainless steel in rolling threads can be solved, furthermore, the middle wall pipeline connected with the threads molded by the machine can be used for replacing the high pressure endured by the thickened tube wall of the molded threads through cutting, the defect that the source nipple loosens and leaks due to stress concentration formed by grooves of cutting threads can be overcome, so that the source nipple can be as rigid as the tube body, and ideal stainless steel thread connection pipelines are provided for tubes of high pressure and middle pressure, particularly the fire control high pressure water mist fire extinguishing system (with the pipeline work pressure of 16MPa).
