Horizontal springback inhibition device applied to waveform piece forming process

The invention relates to a horizontal springback inhibition device applied to the waveform piece forming process. The horizontal springback inhibition device applied to the waveform piece forming process comprises a springback inhibition auxiliary device, a rail conveying device, a core stamping device and an upper computer. After a conventional stamping process is finished, a horizontal springback inhibition step is added, a first power mechanism drives a screw rod to rotate, and the screw rod rotates to drive a sliding seat to slide, so that a first positioning pin is driven to draw close toa second positioning pin; under the control of the upper computer and a ranging module, the feeding amount is accurately controlled; the first positioning pin and the second positioning pin apply pressure on two assembling holes of a sub slice of a formed waveform piece so as to drive the two assembling holes on the waveform piece to get close; and a squeezing board module is matched for extruding the sub slice of the wa
