Steel pipe automatic cleaning machine with the function of supporting and guiding the steel pipe

Abstract

The invention discloses an automatic steel pipe cleaning machine with steel pipe supporting and guiding functions, and belongs to the field of metal pipe cleaning machines. The cleaning machine comprises a cleaning fluid box, a motor, a shaft sleeve transmission wheel, a brush pipe, a circulating fluid supply mechanism and a pair of steel pipe supporting and guiding frames, wherein a bearing pedestal fixing plate and a motor supporting plate are arranged on an opening in the upper portion of the cleaning fluid box; the motor is arranged on the motor supporting plate, and a shaft sleeve is fixed to the center of the shaft sleeve transmission wheel and supported by a shaft sleeve bearing pedestal; the brush pipe is fixed to the shaft sleeve, a brush locating groove is formed in the inner wall of a brush pipe cavity, and a brush is arranged in the brush locating groove; the circulating fluid supply mechanism is arranged in a cleaning fluid box cavity; the steel pipe supporting and guiding frames are located in the same axial line as the brush pipe and fixed to the outer wall of the left end of the cleaning fluid box and the outer wall of the right end of the cleaning fluid box, adjustment grooves are formed in the lower portions of the steel pipe supporting and guiding frames respectively, and the upper portions of the steel pipe supporting and guiding frames form a supporting and guiding cavity. The cleaning machine is small in size, flexible in arrangement and low in cost, and can protect an operator and reduce labor intensity; cleaning fluid can be used as a cooling lubricating agent when workpieces are machined by a machining center or a numerically-controlled machine tool of a machine manufacturing company.

Description

technical field [0001] The invention belongs to the technical field of metal pipe cleaning machinery, and in particular relates to an automatic steel pipe cleaning machine with the function of supporting and guiding steel pipes, which is used to clean the outer wall of the cleaned steel pipe under the state of supporting and guiding. Background technique [0002] During the process of rolling steel pipes in the pipe rolling mill, the wall of the steel pipe, especially the outer wall, is polluted by cold rolling oil, but when the steel pipe enters the commercial channel, it must be kept clean. Therefore, steel pipe manufacturers usually clean the steel pipe before leaving the factory. Pickling. Specifically: the steel pipe is introduced into the pickling tank (also called pickling tank), and the concentration (mass percentage concentration) of nitric acid, hydrofluoric acid or other similar acid solutions is about 30-45% to remove the impurities attached to the steel pipe.

Problems solved by technology

Although this method can ensure the cleaning effect of the steel pipe surface, it has the following disadvantages: First, due to the need to build a pickling pool, the investment cost is high, and it is easily limited by objective conditions. Second, due to the impact of pickling liquid on the environment and the risk of damage to workers' limbs, it is subject to dual constraints from environmental protection and labor protection departments; third, due to the difficulty and high cost of pickling waste treatment , thus increasing the cost of steel pipe production; fourth, because pickling is performed as chemical rather than physical cleaning, there is a chemical corrosion effect on the steel pipe body; Soil is seriously polluted
