Rapid heating and forming integrated device and method

Abstract

The invention discloses a rapid heating and forming integrated device which comprises power sources, an upper die and a lower die and further comprises an upper beam and electrodes. The multiple power sources are arranged. The upper die corresponds to the lower die. A sliding block is fixed to the lower face of the upper beam. The upper die is fixed to the lower face of the sliding block. The lower die is fixed to the upper face of a work table located on a base. A left sealing punch is arranged on the left side of the portion between the upper die and the lower die and a right sealing punch is arranged on the right side of the portion between the upper die and the lower die. A medium channel is formed in the left sealing punch. A medium filling power switch is arranged at the portion, corresponding to the medium channel, on the outer side face of the left sealing punch. The medium channel is connected with a high voltage source through the medium filling power switch. A use method includes ten steps. The device is simple in structure, more scientific and reasonable in design and convenient to use; a blank is rapidly heated in a suspended mode, the low-temperature state of the dies is guaranteed, and a cold die is directly used for conducting thermal treatment in the forming process; meanwhile, different regions are heated at variable temperatures through the multiple electrodes, so that a variable-performance part is formed at a step.

Problems solved by technology

In practical applications, in order to further improve the performance of components, heat treatment is required after forming; however, heat treatment after forming has a series of problems: it will destroy the shape of the part, the process is long at the same time, the production method is cumbersome, and the energy consumption is increased.

Some scholars have proposed to directly heat the billet to the heat treatment temperature in the heating furnace, and then quickly shape it and cool it in the mold to achieve the purpose of heat treatment; however, the heating in the furnace belongs to the overall heating, and it is impossible to realize the variable temperature heating of different regions of the part.

Some scholars have proposed a dual-electrode resistance heating method, but the dual-electrode is only suitable for simple-shaped billets, and it is extremely difficult to control the temperature field for complex shapes, and the device used is complex in structure and cumbersome in operation.
