Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] Such as Figure 1~4 As shown, a welding processing method for a fan casing assembly specifically includes the following steps:

[0046] Step 1: Preparation before welding

[0047] Gather all the components of the fan casing assembly: outer ring 1, blade 2 and inner ring 3, the diameter of outer ring 1 is reserved for 1.2mm, and the deformation of outer ring 1 is reserved for welding; outer ring 1, blade 2 and inner ring 1 The ring 3 is pickled to remove the oxide layer; the outer ring 1 and the inner ring 3 are fixed on the welding fixing tool, and then the blades 2 are assembled on the inner and outer rings one by one to form a fan case assembly;

[0048] The process of fixing the outer ring 1 and the inner ring 3 on the welding fixture: place the inner ring 3 on the support ring 13, cover the step 31 of the inner ring 3 wit...

Abstract

The invention discloses a fan casing assembly welding method and a tool for the fan casing assembly welding method and belongs to the technical field of the welding technology. By the adoption of the fan casing assembly welding method and the tool for the fan casing assembly welding method, the problems that in the welding process, the weld joint forming quality is poor, root reinforcement exists on a weld joint, deformation is serious, dimension errors are large and blade protection is difficult are solved. The fan casing assembly welding method comprises the following steps of preparation before welding, positioning, assembly of a baffle, electron beam welding, inspection after welding, assembly of a heat treatment tool and vacuum heat shaping. The baffle is composed of an upper plate and a lower plate. The fixing tool for welding comprises a base plate, a shaft, a gland, a positioning ring, a supporting ring and a plurality of pressing plates. The heat treatment tool comprises a base plate, a cover plate and a plurality of pressing blocks.

Description

technical field [0001] The invention belongs to the technical field of welding technology, and relates to a welding processing method of a fan case assembly and a tooling used. Background technique [0002] The fan casing assembly is an important load-bearing part of the aero-engine, and the material is TC4. The outer ring of the fan casing assembly and the blade joint are welded by vacuum electron beam. arc excessive) complex curves. [0003] At present, the electron beam welding of the fan case assembly mainly has the following problems: difficult to control the size of the parts, large deformation of the parts, poor quality of weld formation, and difficulty in blade protection. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides a welding processing method of a fan case assembly and the use of tooling. The welding processing method solves the problems of poor weld formation quality, weld back reinforcement...
