Outside polishing device for bended pipe fittings

Abstract

The invention relates to a device which is used for polishing the outer circumferential surface of a bended pipe. An outside polishing device for bended pipe fittings comprises a rack, the rack is provided with a clamping device, a sliding device and a grinding device; the grinding device includes a fixing seat and a driving unit, the fixing seat is provided with a polishing wheel which comprises an inner wheel and an outer wheel in synchronously rotation, the internal wall of the inner wheel is provided with more than two elastic grinding members, the elastic grinding members are arc-shaped, and the outer wheel is connected with the driving unit; the grinding device is connected with the sliding device which comprises a guide frame and a guide trail, and the guide frame moves along the guide rail. The outside polishing device for the bended pipe fittings is simple in structure, even in polishing and high in yield, and without rotation of the pipe fittings to be processed, reduces the processing time, thereby solving the existing technical problems that the polished bended pipe fittings are complicated in structure and uneven in polishing, rotation of the pipe fittings is required during polishing, time and labor are wasted and working efficiency is low in the prior art.

Description

technical field [0001] The invention relates to a polishing device, in particular to a device for polishing the outer peripheral surface of an elbow. Background technique [0002] The polishing process of the outer surface of elbow fittings is an important process in the production process of pipe fittings, which involves the quality of the outer surface of the product. Polishing defects directly affect the wall thickness of the product, making the entire product unqualified, thereby wasting costs and causing greater losses. The traditional polishing method is that the operator holds the bent pipe product close to the high-speed rotating polishing wheel for polishing, and at the same time rotates the product to perform uniform polishing on the circumference until the entire product is polished. The traditional polishing process requires the operator to have certain polishing techniques, and to keep an eye on the changes of the product surface at all times, so as to avoid th...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an external polishing equipment for elbow fittings with simple structure, uniform polishing, no need for rotation of the pipe to be processed, reduced processing time, and high yield; it solves the complex structure of polished elbow fittings in the prior art, The polishing is not uniform, and the pipe needs to be rotated while polishing, which is time-consuming and labor-intensive, and the technical problem of low production efficiency

[0004] At the same time, the invention also provides an external polishing equipment for polishing pipe fittings with different curvatures and easy disassembly, which solves the technical problems of poor versatility, inconvenient assembly and disassembly, and low efficiency in the prior art.
