When the distance measuring sliding seat 202 slides to the bottom wall of the raw material, the sliding high-level surface support base block 203 slides to the concave-convex surface of the high-level surface of the bottom wall of the raw material to abut against it. The supporting hydraulic seat 206 is started simultaneously, so that the supporting hydraulic seat 206 drives the bottom-level surface support base block 205 to slide inside the double dovetail slide groove 204 opened on the side wall surface of the sliding high-level surface support base block 203, so that the top end of the bottom-level surface support base block 205 and the concave-convex surface of the bottom level surface of the bottom wall of the raw material can abut against each other, which can provide stable support, ensure that the raw material will not move or swing during processing or handling, thereby ensuring the processing accuracy and quality, and is conducive to the precise positioning of the raw material at a specific position.It is convenient for subsequent processing, testing or handling operations, reduces vibration and shock during the stamping process, avoids stress offset changes in the raw materials or inaccurate angles of the placed raw materials, which causes the wear coefficient of the mold to increase in the continuous process, resulting in inaccuracy in the stamping of the raw materials. After precise positioning, with the cooperation of the linear guide seat 3 and the sliding guide seat 13, it is convenient to drive the stamping adjustment component 5 for displacement adjustment, which is convenient for achieving precise positioning, and is conducive to adjusting the position and posture of the punch head 58, ensuring the quality and consistency of the raw materials during stamping, and using high-precision ball screw guides 53, high-precision drive control motors 52 and guide sliders 54 to provide stable and smooth linear motion, drive the connecting frame 55 and the hydraulic drive frame 56 to perform high-load and high-precision motion, and when the connecting frame 55 and the hydraulic drive frame 56 move, the optical fiber refractive index sensor 59 is synchronously used to measure the placed raw materials Position detection is performed so that the reversing valve adjustment structure 57 drives the punch head 58 to adjust the positioning accuracy of the raw material to ensure the accuracy and stability of the stamping process. Then, the synchronous electric sliding frame 591 and the punch head 58 are synchronously lowered at a set rate, which is convenient for real-time regulation of the high-speed impact of the punch head 58. After that, with the cooperation of the reinforced force-bearing bracket 41, the I-shaped force-bearing steel frame 42 and multiple groups of reinforced ribs 44, it is convenient to support and buffer the stamping operation, and with the cooperation of multiple groups of pneumatic buffers 43, the impact during stamping is efficiently absorbed and energy is converted to ensure the service life of the entire device for high-load operation. After the stamping is completed, the processed raw materials can be adsorbed by an external vacuum adsorption coding robot arm, and rotated and adjusted inside the clearance frame 7 to the conveyor belt or product rack on the side of the vacuum adsorption coding robot arm, which is convenient for the operation of subsequent processes.
