When the pressing is completed, the first power source and the second drive source move in the opposite direction, causing the fixture mechanism to descend and remove the workpiece from the device. The entire design can achieve high-precision pressing operation and ensure the accuracy and stability of the pressing position through the synergistic effect of the upper pressure head mechanism and the lifting mechanism, as well as the position adjustment of the first self-adjusting component and the second self-adjusting component under the action of the external electric field or magnetic field.The use of a multi-angle positioning device can measure various parameters in the pressing process in real time and transmit the information to the host computer. According to the feedback information, the controller can adjust the position and pressure of the upper pressure head mechanism and the lifting mechanism in time to achieve precise control of the pressing process; in addition, by adjusting the position of the upper pressure head mechanism and the lifting mechanism, as well as the movable design of the fixture mechanism, it can adapt to workpieces of different sizes and shapes, improving the versatility and adaptability of the device; the structural design of the riveted bracket and the close cooperation between the various mechanisms ensure the stability and reliability of the device during the pressing process, and reduce the errors caused by vibration and displacement. The use of the controller realizes the automatic control of the entire device, improving production efficiency and convenience of operation.
