Warm type high-speed forming device for experiments

Abstract

The invention provides a warm type high-speed forming device for experiments. The device comprises a warm forming unit (1) and a buffer temperature control unit (17), and the warm forming unit (1) and the buffer temperature control unit (17) form an integral body through connection of a transmission bar (11). The device is characterized in that the warm forming unit (1) comprises a terrace die (2), a housing (3), an insulating heat shield (4), a ceramic insulating cover (5), a blank holder (6), a die sleeve (7), a heating coil (8), a cooling water pipe (9), a fast flange (10), a female die (12), a heat insulating pad (13), an external stress loop (14), a fastening ring (15) and a fastening screw sleeve (16). The device provided by the invention overcomes the disadvantages that single heating equipment in a laboratory cannot accurately control heating temperature and there is no cooling device in the laboratory; when considerable experiments are carried out, the device can carry out rapid and accurate heating and rapid cooling, which enables experiment efficiency to be improved.

Description

technical field [0001] The invention relates to an experimental device, in particular to a warm forming device for high-speed impact experiments, in particular to an experimental warm-type high-speed forming device used for high-speed impact experiments on difficult-to-form materials such as aluminum-magnesium alloys. forming device. Background technique [0002] As we all know, thermal impact forming is a commonly used forming method for difficult-to-form materials such as aluminum-magnesium alloys. Obtaining the warm forming properties of these materials required extensive experimentation. [0003] Existing thermoforming experiments use a constant temperature heating table (such as KOOCZ heating table), which is composed of a heating tube, a working table, a table body, a temperature controller, and a panel. The working surface of the constant temperature heating table is a square table. When working, place the impact forming material on the work table, and heat the imp...

Problems solved by technology

[0006] The purpose of the present invention is to design a warm-type high-speed heating machine for experiments, aiming at the problem that it can only be roughly heated, but cannot accurately control the temperature, especially when heating difficult-to-form materials. Forming device, so that it can not only heat the difficult-to-form materials accurately in the mold cavity but also allow the materials to undergo high-speed impact within the device, and use the cooling device to cool down the impact-formed materials, while avoiding industrial hot forging molds Applied to the limitations of device size and cushioning that existed during the experiment
