Cold-rolled seamless stainless steel pipe purging and pre-degreasing device

Abstract

The invention provides a purging and pre-degreasing device for a cold-rolled seamless stainless steel pipe, and relates to the technical field of seamless steel pipe machining. Six parallel connecting rods are connected to the outer side of the rotating shaft in a surrounding mode, the rotating shaft is connected with degreasing purging plates through the parallel connecting rods, and the three degreasing purging plates surround the periphery of the rotating shaft in a surrounding mode; the liquid spraying head is communicated with a liquid guide pipe, the liquid guide pipe is connected with a rotary joint, and the rotary joint is arranged on the outer side of the rotary shaft in a sleeving mode. According to different inner diameters of the stainless steel pipes, the spacing distance of the three degreasing and purging plates can be adaptively adjusted, so that hard bristles on the outer sides of the degreasing and purging plates can be in contact with the inner walls of the stainless steel pipes, and the requirements of purging and degreasing treatment of the stainless steel pipes with different inner diameters are better met. The problems that when a traditional purging and degreasing device for the stainless steel pipe is used, a purging and degreasing component in the device is difficult to adjust in applicability according to different inner diameters of the stainless steel pipe, and the universality is poor are solved.

Description

technical field [0001] The invention relates to the technical field of seamless steel pipe processing, in particular to a purging and pre-degreasing device for cold-rolled seamless stainless steel pipes. Background technique [0002] Stainless steel pipe is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument, etc., as well as mechanical structural components. A series of treatments such as degreasing, heat treatment, straightening, pickling and passivation are carried out, so that a relatively smooth stainless steel pipe can be obtained for safe use. [0003] However, when the traditional blowing and degreasing device for stainless steel pipes is currently in use, it is difficult to adjust the applicability of the internal blowing and degreasing components of the device according to the inner diameter of the stainless steel pipe.

Problems solved by technology

[0003] However, when the traditional stainless steel pipe purging and degreasing device is in use, it is difficult to adjust the applicability of the purging and degreasing components inside the device according to the inner diameter of the stainless steel pipe. It can only be used for purging and degreasing the inner wall of a single specification stainless steel pipe When purging and degreasing stainless steel pipes of different specifications, it needs to be repurchased, and the versatility is poor
