Problems solved by technology

[0002] At present, some metal pipes used in the food or medical industry require clean and smooth inner walls, but this kind of pipes often cannot guarantee the smoothness requirements of the inner walls during production. At this time, the inner walls need to be polished. However, these pipes are generally Non-linear or small inner diameter, and relatively long structure, the existing grinding tools can not solve this problem, especially some non-linear or small inner diameter (6mm ~ 12mm), relatively long pipe inner wall grinding problem

Embodiment

[0015] A kind of grinding S-shaped pipe bending tool of the present embodiment, such as figure 1 As shown, it includes a grinding head 2 and a flexible shaft 1, the grinding head 2 is covered on one end of the flexible shaft, and the other end of the flexible shaft 1 is connected to the driving device. The grinding head 2 is a non-woven abrasive flat belt with a nylon base layer, and the non-woven abrasive flat belt with a nylon base layer is glued and coated on the surface of one end of the flexible shaft 1; the flexible shaft 1 includes 4 layers of steel wire winding layers, each The steel wire winding layer is formed by winding 4 to 12 steel wires side by side, and the steel wires are either flat steel wires or round steel wires.

[0016] The grinding S-shaped pipe bending tool in this embodiment utilizes the characteristics of the flexible shaft 1, and the grinding head 2 is equipped with a nylon-based non-woven abrasive flat belt combined with the flexible shaft 1, which ...

Abstract

The invention discloses a tool for grinding an S-shaped bent pipe. The tool comprises a grinding head and a flexible shaft. The grinding head is wrapped at one end of the flexible shaft, and the other end of the flexible shaft is connected with a driving device. The grinding head is a non-woven abrasive bandlet with a nylon base layer, and the non-woven abrasive bandlet with the nylon base layer is attached to and wrapped on the surface of one end of the flexible shaft through glue. The flexible shaft is provided with at least two steel wire winding layers, 4 to 12 steel wires are wound side by side to form each steel wire winding layer, and the steel wires are one of flat steel wires and round steel wires. By means of the tool for grinding the S-shaped bent pipe, the characteristics of the flexible shaft are used, the non-woven abrasive bandlet with the nylon base layer of the grinding head is combined with the flexible shaft, and therefore the problem of grinding the inner wall of a pipe which is in a non-linear shape or has a small inner diameter ranging from 6mm to 12mm and is of a long structure can be effectively solved, and the tool for grinding the S-shaped bent pipe is simple in structure, convenient to operate, high in automation degree and suitable for production.

Description

technical field [0001] The invention relates to the field of grinding machines, in particular to a grinding S-shaped bending tool connected with a flexible shaft. Background technique [0002] At present, some metal pipes used in the food or medical industry require clean and smooth inner walls, but this kind of pipes often cannot guarantee the smoothness requirements of the inner walls during production. At this time, the inner walls need to be polished. However, these pipes are generally Non-linear or small inner diameter, and relatively long structure, the existing grinding tools can not solve this problem, especially some non-linear or small inner diameter (6mm ~ 12mm), relatively long pipe inner wall grinding problem . Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a grinding S-shaped pipe bending tool, which can grind non-linear or small inner diameter (6mm ~ 12mm), relati...
