Abstract

The invention relates to a manufacturing method of a locking ring and used fixtures, which belong to the technical field of aircraft engines. By using the manufacturing method and the used fixtures, the technical problems of easiness in deformation and difficulty in tight winding and forming due to the fact that a flat wire is used for winding the locking ring are successfully solved. The manufacturing method has the technical scheme that the manufacturing method of the locking ring comprises the following steps of preparation of raw materials, preparation of winding, winding of the flat wire, forming of the locking ring and heat treatment for forming. An auxiliary winding fixture special for the locking ring comprises a base, wherein a shell is arranged on the base, and an outer roller and an inner roller are arranged in the shell. A rectangular thread slot winding fixture special for the locking ring comprises a core rod, wherein a core rod step is arranged on the core rod, a step rectangular slot is formed in the core rod step, a bolt is arranged on one side of the step rectangular slot, and a washer is arranged between the bolt and the core rod step. A forming fixture special for the locking ring comprises a forming base, wherein an inner step is arranged inside the forming base, and a pressure plate is arranged above the forming base.

Description

technical field [0001] The invention belongs to the technical field of aero-engines, and in particular relates to a method for manufacturing a locking ring and a clamp used therefor. Background technique [0002] Such as figure 1 , figure 2 As shown, the general lock ring is formed by winding flat steel wires. Since the flat steel wires have a wider cross-section and greater stress, they are prone to deformation. Such as image 3 , Figure 4 As shown, when the flat steel wire is bent and wound on the basis of the thickness surface, the winding angle is relatively large, and the deformation stress is also large. The outer side of the flat steel wire is subjected to tensile stress and the inner side is subjected to compressive stress. That is, the outside has a tendency to bend upwards or downwards. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a method for manufacturing the lock ring and the clamp u...
