Device for scrubbing metal pipe inner wall

Abstract

The invention discloses a brushing and washing device used for the internal wall of a metal pipe, comprising a mainshaft (1); the mainshaft (1) is provided with a steel brush (2). The brushing and washing device is characterized in that the mainshaft (1) is also provided with a three-direction supporting frame (3); a rotation mechanism is connected with the mainshaft (1); the moving mechanism of the metal pipe is arranged in the direction of the mainshaft (1). The brushing and washing device has the outstanding advantages that the repeated rotation cleaning motion of the existing steel brush is disassembled as the single rotation motion of the steel brush and the single reciprocating motion of the metal pipe, the mechanism is greatly simplified, and the cost is reduced. Meanwhile, the mainshaft is provided with the three-direction supporting frame which rotates with the steel brush; therefore, the collapsing deformation of the metal pipe is prevented, the collapsing deformation of the metal pipe can be repaired, the concentric rotation of the steel brush in the axis line direction of a copper pipe can be basically ensured, and the product quality is ensured.

Description

Technical field: [0001] The invention relates to a device for cleaning the inner wall of a metal pipe. Background technique: [0002] Most metal pipes need to be cleaned before further processing or after production to remove oil, dust, metal oxide layers and other impurities on the surface. At present, most of the devices for cleaning the inner wall of the metal pipe fix the metal pipe first, and then use a steel brush with a diameter slightly larger than the diameter of the metal pipe to reciprocate in the pipe. The above-mentioned devices cannot meet the quality requirements for brushing. And the metal pipe with thinner pipe wall is prone to collapse and deformation phenomenon when brushing. Invention content: [0003] The present invention aims at the above-mentioned deficiencies of the prior art, and provides a brushing device for cleaning the inner wall of the metal pipe with simple structure, high efficiency and thorough cleaning. [0004] The technical solution o...
