Self-adaptive sand-blasting polishing device for aluminium alloy bend pipe

Abstract

The invention relates to the field of aluminium alloy bend pipe polishing, in particular to a self-adaptive sand-blasting polishing device for an aluminium alloy bend pipe. The device comprises a centering fixture mechanism, a guiding sliding mechanism, a horizontal ring-shaped sand-blasting pipe, a horizontal guiding rail, a lifting mechanism, a centering base, a one-way pushing mechanism, a pressing rail, a vertical ring-shaped sand-blasting pipe, a containing box body, and a pushing box body. The self-adaptive sand-blasting polishing device for the aluminium alloy bend pipe realizes the automatic clamping of the aluminium alloy bend pipe, ensures the equal distance between the outer wall of the aluminum alloy bend pipe and the inner side of the horizontal ring-shaped sand-blasting pipe,and ensures that the brightness of the external wall of the aluminum alloy bend pipe is basically the same after polishing, so that the device can polish all aluminum alloy bent pipes with differentheights, and polish both sides of the aluminum alloy bent pipe simultaneously, so as to improve the working efficiency of the device and reduce the working time of a worker.

Description

technical field [0001] The invention relates to the field of grinding of aluminum alloy bent pipes, in particular to an adaptive sandblasting and grinding equipment for aluminum alloy bent pipes. Background technique [0002] The sandblasting process is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material onto the surface of the workpiece to be processed at high speed, and then polish the workpiece. The distance between the sandblasting gun and the workpiece is different, and the sandblasting effect on the workpiece will be different. [0003] my country's patent application number: CN201811535819.2; discloses a continuous aluminum alloy pipe sandblasting device, using the sandblasting channel formed in the middle of the sandblasting ring to achieve uniform sandblasting treatment on a single aluminum alloy pipe, to achieve alumin...

AI Technical Summary

Problems solved by technology

[0005] 1. Although this scheme can sandblast and polish the outer wall of the aluminum alloy pipe through the sandblasting ring, this scheme cannot sandblast and polish the aluminum alloy elbow, so that the aluminum alloy elbow can only be polished by workers. waste of workers' time

[0006] 2. Even if the workers grind the aluminum alloy elbow through the equipment, because the aluminum alloy elbow is in a bent state, the grinding on both sides needs to be carried out step by step

[0007] 3. For aluminum alloy elbows with different diameters, it is difficult to ensure that the aluminum alloy elbow is coaxial with the sandblasting ring during grinding, so that the distance from the outer wall of the aluminum alloy elbow to the inner wall of the sandblasting ring is different, which will make the aluminum alloy bend The brightness of the grinding of the pipe is different, which affects the processing quality of the aluminum alloy bend pipe
