High-temperature alloy elastic seal piece processing technique and mould thereof

Abstract

The invention relates to a high-temperature alloy elastic seal piece processing technique and a mould thereof, and the processing technique and the mould belong to the technical field of sheet metal stamping. The invention provides the high-temperature alloy elastic seal piece processing technique and the mould thereof, and the processing technique and the mould thereof simplify a process flow and process equipment, reduce the production cost and the assembly difficulty, and improve the working efficiency. The invention adopts the following technical scheme: the high-temperature alloy elastic seal piece processing technique comprises the following steps that strips are cut; the strips are stamped and grooved; stepper bending and formation are carried out; solution aging heat treatment is carried out; and openings are welded. The mould which is used in the stepper bending and formation comprises a lower template; the top of the lower template is provided with a lower backing plate and a concave mould in sequence; a convex mould is arranged above the concave mould; the concave surface of the concave mould corresponds to the convex surface of the convex mould; a baffle is arranged beside the top of the concave mould; an upper backing plate and an upper template are arranged on the top of the convex mould in sequence; and the upper template and the lower template are connected through a guide column and a guide sleeve.

Description

technical field [0001] The invention belongs to the technical field of sheet metal stamping, and in particular relates to a processing technology for a high-temperature alloy elastic seal. Background technique [0002] The structure of the elastic seal is as follows figure 1 As shown, it is generally obtained by sheet metal stamping. [0003] The traditional process is: cutting strips, rollers, welding tube blanks, integral stamping and bulging, punching and grooves, solution aging heat treatment, etc. [0004] There are many types of stamping bulging. From the shape of the billet, there are local bulging of flat billets (including beading, embossing, etc.) and hollow billets with or without bottoms; from the mold used, there are rigid mold bulging and semi-rigid mold bulging. Shape and soft mold bulging, etc. Elastic seals are used to bulging cylindrical hollow blanks. The mold structure is complex. It is an inner and outer two-layer split module. The two-layer modules ...

Problems solved by technology

This process not only causes the shortcomings of the bulging process itself, such as large mold structure, difficult manufacturing, long debugging cycle, and high cost, but also because the punching and punching molds with curved surface bands must be designed as relatively large and complex cantilever structures. The number of furnaces cannot be too many due to the limitation of the whole ring structure and the relative difficulty of component assembly, which brings difficulties to the subsequent processing of the bulging process and increases the cost
