Surface treatment equipment for metal corrugated pipe machining

Abstract

The invention discloses surface treatment equipment for metal corrugated pipe machining. The surface treatment equipment comprises a supporting frame, wherein a fixing ring is fixed to the position, close to the middle, of the supporting frame; a rotating sleeve used for grinding is rotationally installed inside the fixing ring; grinding mechanisms used for grinding the surface of an annular corrugated pipe are symmetrically arranged inside the rotating sleeve; a transmission mechanism used for intermittent feeding and clamping of the annular corrugated pipe is connected to the supporting frame; a driving mechanism used for driving the rotating sleeve to rotate and enabling the transmission mechanism to operate is further connected to the supporting frame; and a double-cam mechanism used for left-right movement of a mounting frame and up-down movement of a clamping plate is connected to the supporting frame. According to the surface treatment equipment, the fitting effect of water pressure is utilized, on one hand, the grinding quality is improved, and meanwhile, local deformation caused by too large stress can be avoided; and meanwhile, a grinding head is contracted under the action of the water pressure, and feeding type grinding of the metal corrugated pipe is facilitated.

Description

technical field [0001] The invention relates to the technical field of metal bellows processing, in particular to a surface treatment device for metal bellows processing. Background technique [0002] Metal bellows refers to metal pipes made of galvanized or non-galvanized low-carbon steel strips with spiral folded bites and used to reserve holes in post-tensioned prestressed concrete structural members. The ring-shaped stainless steel bellows are corrugated in a closed ring shape The tubular shell is formed by ring corrugations in series between waves. Annular bellows are formed from seamless or welded pipes. Restricted by the processing method, the length of a single tube is usually shorter than that of a spiral corrugated tube. The advantages of the ring bellows are good elasticity and low rigidity. The existing surface treatment equipment for metal bellows processing is aimed at the ring bellows, because there are grooves between the pipe walls. On the one hand, it is ...

AI Technical Summary

Problems solved by technology

The advantages of the ring bellows are good elasticity and low rigidity. The existing surface treatment equipment for metal bellows processing is aimed at the ring bellows, because there are grooves between the pipe walls. On the one hand, it is difficult to make the grinding head fit with it. The grinding head is located in the groove of the ring bellows, because of its position-limiting effect, it is difficult to grind the pipeline in a feeding manner, and the work efficiency is low
