Composite thermoforming mould of titanium alloy part and thermoforming method applying mould

Abstract

The invention relates to the field of a titanium alloy work-piece thermoforming, in particular to a composite thermoforming mould of a titanium alloy part. The mould only comprises two branch moulds, twice heating can be needed only when a special work-piece is processed, and the twice manual operation is needed, therefore the cost of the mould, the heating cost and manual cost of thermoforming equipment can be reduced. The invention discloses a thermoforming method applying the mould. The heating cost and manual cost of thermoforming equipment can be reduced.

Description

technical field [0001] The invention relates to the field of thermoforming of titanium alloy workpieces, in particular to a composite thermoforming die for titanium alloy parts and a thermoforming method using the die. Background technique [0002] "Titanium alloy", in sheet metal forming in the manufacturing industry, especially in sheet metal hot forming. Almost everyone talks about titanium discoloration. Titanium alloy is not only the physical and chemical properties of the material itself that determine its stamping effect in the traditional mode is difficult to achieve (such as high tensile strength, low elongation, brittleness at room temperature, etc. will not be repeated here), but also because Its high price, limited scope of use (mostly only used in aerospace and other industries in the medical device industry rarely come into contact with such materials) and other factors make it extremely scarce in the industry for reference or reference data and experience, co...

Problems solved by technology

Titanium alloy is not only the physical and chemical properties of the material itself that determine its stamping effect in the traditional mode is difficult to achieve (such as high tensile strength, low elongation, brittleness at room temperature, etc. will not be repeated here), but also because Its high price, limited scope of use (mostly only used in aerospace and other industries in the medical device industry rarely come into contact with such materials) and other factors make it extremely scarce in the industry for reference or reference data and experience, conventional forming methods Most of the information that can be collected is only at the theoretical stage and lacks practical operability, which makes the development of the forming technology of this material extremely slow.

Throughout the domestic sheet metal manufacturing industry, the most common complaints in the manufacturing process are "long cycle time" and "high cost". The performance of all aspects of the cycle and forming process means makes it difficult to improve the production efficiency of parts

The high cost is mainly due to the higher unit price of mold materials for forming titanium alloy parts than ordinary conventional materials and the high heating cost of hot forming equipment required for forming titanium alloy parts. At the same time, due to the first two main reasons, the overall production time is lengthy, resulting in serious production capacity consume
