Problems solved by technology
Although the system is similar to the construction equipment, for the loading process of the construction metal, the deformation amount, deformation speed, and loading pressure need to be precisely controlled, and the system is also difficult to meet the test requirements.
[0007] To sum up, currently there are few equipments on the market that meet the requirements of construction tests, and there are almost no equipment specially designed for construction forming tests.
Moreover, the metal structure forming mechanism of a small number of materials has been explained, but the metal structure forming mechanism of most materials has yet to be resolved

The invention discloses a precision control device and method for metal structure forming deformation parameters. The control device includes a mechanical loading module, a compression module, a vacuum module, a heating module, a ventilation module, a moving module and a control system. The present invention adopts a mechanical loading module, and the precise control of loading parameters can be realized through the servo motor, reducer and ball screw. Compared with the hydraulic device, the present invention can reduce the hydraulic pump station and oil valve equipped with the hydraulic loading module, and the equipment is simple , the cost is lower. According to the selection of a suitable mechanical loading module, the present invention can realize a maximum size of 40*40*40mm, a loading pressure of 20t, and a loading speed of 0-20mm / s. The invention can realize the requirements of the forming process of the metal structure, that is, under vacuum conditions, heat to a specified temperature and keep it warm, and then load the structure sample according to constant pressure and constant speed, so as to realize the deformation amount, deformation speed and deformation temperature of the metal structure forming precise control.
Description
technical field [0001] The invention relates to welding equipment and the technical field thereof, in particular to a device and method for precise control of metal structure forming deformation parameters. Background technique [0002] As the core components of major projects, large forgings are often served under extreme conditions such as high temperature, high pressure, irradiation, corrosion, reciprocating motion, etc., which have extremely high requirements on the performance of materials, especially the homogeneity. my country's large forgings have long relied on imports, but even imported forgings sometimes have problems of homogenization. The internal metallurgical quality of the base material and large ingot of large forgings is often extremely difficult to guarantee, the solidification process is difficult to control, macro segregation, cracks, center porosity and coarse grains are serious, resulting in a very low pass rate of large forgings, which greatly increas...
