Special-shaped pipe sawing method

Abstract

The invention provides a special-shaped pipe sawing method. The special-shaped pipe sawing method comprises the following steps: milling a process hole in a pre-punching position of a special-shaped pipe in a pipe fitting to be sawed; putting the pipe fitting which has part of the special-shaped pipe into a clamp to be clamped; sawing the special-shaped pipe from the pipe fitting; putting the special-shaped pipe sawed in the last step into a first special-shaped pipe clamp; sawing a first pipe opening of the special-shaped pipe; reversely putting the special-shaped pipe sawed in the last step into a second special-shaped pipe clamp; sawing a second pipe opening of the special-shaped pipe; removing burrs of the two pipe openings by a grinding machine; forming a connection hole of the special-shaped pipe; reshaping, removing the burrs and washing to finish the method, wherein the hole diameter of the connection hole is larger than that of the process hole. When the method is used for sawing, the special-shaped pipe does not shake and the sawing effect is better; the position of the process hole is formed and needs to be expanded to form the connection hole in subsequent machining so that the whole shape of the special-shaped pipe is completely not influenced; the special-shaped pipe sawing method is simple and convenient and has better machining effect.

Description

technical field [0001] The invention relates to the field of pipe material processing, in particular to a sawing method for special-shaped pipes with connecting holes. Background technique [0002] In the field of pipe fittings processing, for sawing of straight pipes, the straight pipe clamp is generally used to clamp the straight pipe, and then sawed, while for the sawing of special-shaped pipes, the special-shaped pipe is generally clamped by the special-shaped pipe clamp, and then sawed In this method, due to the irregular shape of the special-shaped tube, in order to be able to clamp the special-shaped tube, a cavity slightly larger than the shape of the special-shaped tube is generally provided in the special-shaped tube clamp to facilitate the clamping of the special-shaped tube, but due to both There is still a gap between them, so the special-shaped pipe will still loosen on the fixture, so when sawing, the sawing effect is often not good, and deviations will occur,...

[0002] In the field of pipe fittings processing, for sawing of straight pipes, the straight pipe clamp is generally used to clamp the straight pipe, and then sawed, while for the sawing of special-shaped pipes, the special-shaped pipe is generally clamped by the special-shaped pipe clamp, and then sawed In this method, due to the irregular shape of the special-shaped tube, in order to be able to clamp the special-shaped tube, a cavity slightly larger than the shape of the special-shaped tube is generally provided in the special-shaped tube clamp to facilitate the clamping of the special-shaped tube, but due to both There is still a gap between them, so the special-shaped tube will still be loose on the fixture, so when sawing, the sawing effect is often not good, and deviations will occur, and finally it still needs to be shaped, the operation is troublesome, and the sawing effect is not good

Once there is a deviation during the sawing process, it will be very difficult to shape the final product, which will often result in a low pass rate of the product
