Thermal shaping system and thermal shaping method

Abstract

The invention relates to a thermal shaping system and a thermal shaping method. The thermal shaping system comprises a mechanical arm, at least one thermal shaping device and a cooling device, whereinthe mechanical arm is used for taking and placing workpieces, at least one thermal shaping device is sequentially arranged around the mechanical arm clockwise or counterclockwise, each thermal shaping device comprises an upper die and a lower die which are oppositely arranged up and down, the upper dies and the lower dies are matched to form cavities so as to press-fit and shape to-be- shaped workpieces placed in the cavities, each thermal shaping device further comprises a heating mechanism connected with the upper die and / or the lower die, each heating mechanism can heat the upper die and / or the lower die to a preset temperature to carried out thermal shape on the workpiece pressed on the cavity, and the cooling device is used for cooling and forming at least one workpiece shaped by theat least one thermal shaping device through the cooling device. According to the thermal shaping system and the thermal shaping method, the mechanical deformation and the hot pressing deformation arecombined, so that the shaping efficiency and the shaping effect of the product can be improved, the product yield can be improved, and the jig cost and the labor cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of thermal shaping of workpieces, in particular to a thermal shaping system and a thermal shaping method. Background technique [0002] The thinner wall thickness of thin-walled parts determines that its ability to resist internal stress deformation and external force deformation is poor, and it is prone to deformation. This deformation phenomenon is particularly serious when the product structure of thin-walled parts is complex, and the wall thickness of each part is greatly different, especially in the processing processes such as casting, stamping, CNC machining, grinding, handling and extrusion, which are easily caused by internal stress and external force. Action produces deformation. In order to ensure the quality of thin-walled parts, it is necessary to reshape the deformed thin-walled parts to meet the requirements of its appearance and product structure assembly relationship. [0003] The existing...

Problems solved by technology

Although the mechanical stress relief method can meet the flatness requirements of the product in a short period of time, because the internal stress is not completely eliminated, the residual internal stress will cause the product to automatically deform over time

The thermal aging stress relief method achieves the purpose of stress relief by placing the workpiece on a profiling jig and putting them together in an oven for aging heat treatment. However, the development cost of the jig is high, the manpower requirement for plastic surgery is high, and there is a burn operation at high temperature. personnel risk
