Problems solved by technology

[0002] In modern society, with the continuous development of productivity and the continuous improvement of scientific and technological living standards, the development of the forging industry is rapidly improving, and the processing methods of forging products are increasing. The drawing processing of plates is the most common, but the residual stress of drawing processing is very large and it is easy to produce backlashes. Elastic phenomenon, when a stamping part is formed, that is, at the end of the forming step, there are residual stresses in the volume of the sheet, and these residual stresses are balanced with the contact force of the tool. When the tool is released, the formed part is removed from the mold When the plate will find a new equilibrium position, the local residual stress is released, resulting in a certain deviation between the final size of the formed part and the expected value, that is, the phenomenon of springback. Therefore, a device for controlling the springback of plate forming is invented.

Embodiment

[0026] Example: such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 Shown is a device for controlling the springback of sheet metal forming. Including a conveying device 1, a compacting device 2, and a tempering device 3, the processing method includes the following steps: ① put the plate on the conveying device after processing; ② transport the plate to the compacting device through the conveying device; ③ when the plate enters Start to apply pressure to the plate when it reaches the inside of the pressing device; ④ transport the plate to the tempering device after a period of time; ⑤ slowly heat the plate for a period of time; ⑥ cool the plate after heating for a period of time.

[0027] Such as image 3 As shown, the power motor 102 is welded on the motor bracket 101, the driving wheel 103 is fixedly connected to the power motor 102, the belt 104 is slidably connected to the driving wheel 103, the driven wheel 105 is rotatably connected to the output rod 1...
