A kind of thermal insulation tooling for hot drawing and bending of profiles

Abstract

The invention discloses a thermal insulation tooling for thermal stretch bending of profiles, which is characterized in that it includes at least two identical and independent thermal insulation modules, and the thermal insulation module includes a supporting metal outer wall, a thermal insulation inner wall, a thermal insulation board, a temperature measuring Thermocouple, auxiliary heating unit, hinge mechanism. Through the technical solution of the invention, it can be bent according to the curvature of the part, which improves the flexibility of the thermal insulation tooling, so that it can meet the needs of hot stretch bending of titanium alloy curved surface components of various sizes, and is easy to install, which can effectively improve production efficiency and reduce Tooling costs.

Description

technical field [0001] The invention belongs to the field of hot stretch bending of metal profiles, and in particular relates to heat preservation process equipment for hot stretch bending of profiles. Specifically, it is an expandable flexible heat preservation tool with modular design. Background technique [0002] In order to reduce weight and improve economy, the new generation of large aircraft uses a large number of carbon fiber composite skins. The strength, stiffness, and thermal characteristics of titanium alloy and carbon fiber composite material are well matched, and the potentials of the two are close, which is not easy to cause galvanic corrosion. Moreover, titanium alloy itself has a series of excellent characteristics such as high specific strength, good corrosion resistance, and high temperature resistance. Therefore, the load-bearing skeleton connected with the composite skin mostly adopts titanium alloy curved surface components. [0003] Titanium alloy cu...

Problems solved by technology

[0006] However, the existing thermal insulation tooling of this type is a fixed-volume structure, that is, each size of thermal insulation tooling can only meet the hot-drawing forming requirements of a small number of parts.

However, there are many sizes of titanium alloy curved surface components. If thermal insulation tooling of various sizes is manufactured, the cost of the tooling will be too high

At the same time, for large-sized hot-drawn profiles, the insulation tooling is too bulky and cumbersome, which is very inconvenient to carry and unload, which seriously reduces production efficiency
