Rapid bending method of engine 360-degree circular ring pipe part

Abstract

The invention discloses a rapid bending method of an engine 360-degree circular ring pipe part. The rapid bending method comprises the following steps that 1) a pipe material is cut and obtained; 2) rosin fills the pipe material; 3) the pipe material is clamped and positioned on a bending tool, then the bending tool is clamped on three claws of a machine tool, then the bending tool is driven to rotate through the machine tool, meanwhile, a rolling wheel is additionally arranged on a knife tower, furthermore, the rolling wheel is attached to the pipe material, meanwhile, the rolling wheel is enabled to axially move along the molded surface of a bending die, and in the moving process, it is ensured that the rolling wheel is always attached to the pipe material; 4) the pipe material is corrected on the bending tool, so that the pipe material is attached to the molded surface of the bending tool, and the bending shape of the pipe material is guaranteed to be qualified; and 5) the rosin inthe pipe material is removed, and then burr removing treatment is carried out to obtain the engine 360-degree circular ring pipe part. According to the rapid bending method, rapid bending of the engine 360-degree circular ring pipe part can be achieved, errors caused by manual operation can be avoided, the operation intensity of the bending personnel can be reduced, and the machining efficiency ishigh.

Description

technical field [0001] The invention belongs to the field of rapid bending processing, and relates to a rapid bending method for 360° circular pipe parts of an engine. Background technique [0002] For the structure of a certain type of aero-engine 360° circular tube parts, see Figure 1a and Figure 1b , the material is stainless steel 1Cr18Ni9Ti, and the pipe material of φ10*1 is used. At present, 360° circular tube parts are generally filled with materials such as rosin in the lumen, and manually bent by using a bending mold. The bending strength is high, the efficiency is low, and due to the poor uniformity of the force during the bending process, the ellipticity of the pipe after bending will increase. [0003] At present, the processing method of such 360° circular pipe parts is as follows: [0004] 1. Cutting: Cut the pipe material into a certain length with a grinding wheel, which can meet the perimeter of the bent part. [0005] 2. Filling with rosin: Fill the i...

Problems solved by technology

[0011] This kind of processing plan requires a high level of skill of the operator. When bending the pipe with the bending die, it is required that the strength of the strong person should be uniform and continuous, otherwise the ellipticity of the pipe after bending will increase; moreover, the set The bending method is manual bending, which has high bending strength and low efficiency
