Metal corrugated pipe manufacturing and machining process

Abstract

The invention relates to a metal corrugated pipe manufacturing and machining process. The metal corrugated pipe manufacturing and machining process adopts the following machining machinery. The machining machinery comprises a base and a lifting device arranged on one side of the top of the base, wherein a corrugated pipe body is arranged above the base; fixing devices are mounted on the base and the lifting device correspondingly; a mounting frame is arranged on one side of the fixing device mounted on the base; and a grinding device penetrating through the corrugated pipe body is mounted on the side wall of the mounting frame. According to the metal corrugated pipe manufacturing and machining process, the inclination of a round rod is changed through stretching and retracting of a secondspring, thus the distance between grinding heads and a first rotary shaft is changed, and the grinding heads in different planes can conduct comprehensive grinding on wave crests and wave troughs of ametal corrugated pipe; the grinding heads conduct revolution and rotation simultaneously, so that the grinding efficiency is improved; and the fixing device at one end of the corrugated pipe is driven by the lifting device to move, thus the corrugated pipe is in an inclined state, ground dirt can fall down conveniently, and meanwhile, foreign matter remaining at the wave troughs is wiped away through cooperation of a cleaning mechanism.

Description

technical field [0001] The invention relates to the technical field of bellows processing, in particular to a metal bellows manufacturing process. Background technique [0002] Metal bellows is a pipe that looks like a regular wave. Commonly used metal bellows include carbon steel and stainless steel, as well as steel-lined plastic and aluminum. It is mainly used for non-concentric axial transmission with small bending radius, irregular turning, expansion and contraction, or absorption of thermal deformation of pipelines, etc., where it is not convenient to use fixed elbows to connect pipelines, or to connect pipelines with equipment connection use. [0003] After the processed bellows are segmented, the inner wall needs to be inspected to see if there are foreign objects including process scale accumulated in the bellows. Therefore, the bellows needs to be further refined, and the foreign matter or process scale on the inner wall should be polished and removed. ; The exis...

It is mainly used for non-concentric axial transmission with small bending radius, irregular turning, expansion and contraction, or absorption of thermal deformation of pipelines, etc., where it is not convenient to use fixed elbows to connect pipelines, or to connect pipelines with equipment connection use

[0003] After the processed bellows are segmented, the inner wall needs to be inspected to see if there are foreign objects including process scale accumulated in the bellows. Therefore, the bellows needs to be further refined, and the foreign matter or process scale on the inner wall should be polished and removed. ; The existing grinding device has the following disadvantages: one, the inner wall of the metal bellows is wavy, and the troughs are not easy to be polished when grinding, resulting in foreign matter or dirt still in the bellows; The foreign matter or scale easily remains in the trough of the bellows when it is removed, and cannot be completely discharged
