Abstract

This utility model discloses a stamping device for the inner panel of a car B-pillar, relating to the field of stamping device technology. It includes an operating table, a fixing component, a mold component, a stamping component, and a cleaning component. The fixing component, mold component, stamping component, and cleaning component are installed on the upper part of the operating table. The fixing component includes a mold mounting groove, an electromagnetic device, a pressure monitoring device, a mounting groove, a sliding block, a connecting rod, a fixing plate, a fixing block, a dual-axis motor, and a threaded rod. The upper center of the operating table has a mold mounting groove, and the inner center of the mold mounting groove is equipped with a pressure monitoring device. An electromagnetic device is embedded in the four corners of the inner side of the mold mounting groove. The upper front side of the operating table has a mounting groove. This stamping device for the inner panel of a car B-pillar allows for quick mold replacement and rapid mold demolding after stamping to prevent parts from sticking to the mold after stamping.
