Problems solved by technology

But the important thing is to master the annealing temperature. If the temperature is too low, the annealing is insufficient, and the effect of eliminating internal stress cannot be achieved; Meet the requirement that the surface roughness of the part is less than 1.6μm, and greatly reduce the strength of the part to make it invalid

Abstract

The invention relates to a process for manufacturing a disc, in particular to a process for manufacturing opening discs of a separator, which comprises the following working procedures: blanking, blanking round stock, punching fabrication holes, rotary extrusion, edge turning, punching splined holes, punching evenly distributed holes on a conical surface, spot welding of ribs and polishing, wherein a heat treatment working procedure adopting annealing is added between the rotary extrusion working procedure and the edge turning working procedure, and the annealing temperature is between 700 and 800 DEG C and the heat preservation time is between 5 and 15min. Because the process for manufacturing the opening discs of the separator increases the heat treatment working procedure, the internal stress is eliminated fully, the atom dislocation is greatly recovered, the plasticity is improved obviously, and the aim of reducing deformation of openings of the discs is achieved; and the process retains certain deformation strengthening function, so parts have certain hardness and strength to meet the requirement on service performance of the parts.

Description

technical field [0001] The invention relates to a manufacturing process of a disc, in particular to a manufacturing process of an opening disc of a separator. Background technique [0002] The manufacturing process of the existing splitter opening disc is as follows: blanking, falling round material, punching process holes, spinning, turning, punching spline holes, punching evenly distributed holes on the cone surface, spot welding ribs, polishing . When the open disc produced by this process is used to separate oily materials in the separator, the disc is prone to slagging, which affects the separation effect. The main manifestations are: during production, the open disc produces considerable deformation at the opening. After the opening, the straightness of the cone busbar reaches 1-4mm, and the out-of-roundness of the outer circle of the large end reaches more than 4mm. Its shape has changed from circular becomes polygonal and cannot be used at all. [0003] Through re...
