Pretreatment device for square hollow pipe machining

Abstract

The pretreatment device for square hollow pipe machining comprises a workbench, a rack is fixedly mounted on the outer wall of the left side of the top of the workbench, and an electric telescopic rod is fixedly mounted on the outer wall of the top of the rack; the bottom end of the electric telescopic rod extends into an inner cavity of the rack and is fixedly connected with the cleaning device, paint spraying equipment is fixedly installed on the outer wall of the right side of the top of the workbench, two sets of baffles are arranged on the outer wall of the top of the workbench, and the device makes contact with the outer wall of the top of a square hollow pipe through a guide wheel, so that a guide rod can drive a moving plate to move downwards through a connecting rod; when the cleaning device works, the brush bristles in the middle move downwards, so that the brush bristles in the middle make full contact with the concave area of the top of the square hollow pipe, the situation that the distance between the brush bristles and the concave area of the square hollow pipe is large, and consequently force applied to the brush bristles is small is avoided, it is guaranteed that the cleaning device completes cleaning at a time, and working quality and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the technical field of square hollow tube processing equipment, in particular to a pretreatment device for square hollow tube processing. Background technique [0002] When painting the pipe, the pipe needs to be pretreated. Now the pretreatment device is used to treat the mud on the outer wall of the square hollow pipe. Generally, the brush is used to slide the outer wall of the pipe to remove the mud attached to the outer wall of the pipe. However, due to the square The interior of the hollow tube is hollow, so the surface of the outer wall of the square hollow tube is prone to dents inward. When pretreatment is performed on the square hollow tube with a sunken area on the surface, the brushes will be in contact with the outer wall of the square hollow tube because the brushes are neat. The distance between the recessed areas is relatively large, which causes the brush to exert less force on the recessed area than other areas...

[0002] When painting the pipe, the pipe needs to be pretreated. Now the pretreatment device is used to treat the mud on the outer wall of the square hollow pipe. Generally, the brush is used to slide the outer wall of the pipe to remove the mud attached to the outer wall of the pipe. However, due to the square The interior of the hollow tube is hollow, so the surface of the outer wall of the square hollow tube is prone to dents inward. When pretreatment is performed on the square hollow tube with a sunken area on the surface, the brushes will be in contact with the outer wall of the square hollow tube because the brushes are neat. The distance between the recessed areas is relatively large, which causes the brush to exert less force on the recessed area than other areas. Due to the certain adhesion between the soil and the outer wall of the square hollow tube, the soil in the recessed area cannot be cleaned thoroughly, which affects work efficiency. and quality, and the concave area is arc-shaped, which will cause the brush to not fully contact the arc-shaped wall of the concave area, and also affect the quality of work. Therefore, we propose a pretreatment for square hollow tube processing device
