The telescopic support column 221 is fixedly installed on the inner side of the bottom end of the stamping lower die 211, and the bottom end pin shaft of the telescopic support column 221 is connected to the hydraulic telescopic wheel 222. When the stamping lower die 211 moves, the hydraulic telescopic wheel 222 is started to extend it from the stamping lower die 211, and the stamping lower die 211 is slightly lifted to improve its movement convenience. When it is not moving, the hydraulic telescopic wheel 222 is retracted to avoid the hydraulic telescopic wheel 222 being crushed during sheet metal stamping.

[0029] Furthermore, the clamping assembly 23 includes a clamping base plate 231, a hydraulic telescopic rod 232 and a clamping fixed plate 233. The left and right end slots of the machine tool body 1 are connected to the clamping base plate 231, the top of the clamping base plate 231 is installed with a hydraulic telescopic rod 232, and the top of the hydraulic telescopic rod 232 is fixedly installed with a clamping fixed plate 233.

The stamping force of the stamping spindle 32 is controlled by the stamping controller 35. The thicker the sheet metal, the greater the stamping force, thereby ensuring the accuracy of the sheet metal after forming.

[0035] Working principle: When in use, the first step is to install the device at the desired location, then start the hydraulic telescopic wheel 222 to extend it from the stamping lower die 211, slightly lift the stamping lower die 211, and then drive the stamping lower die 211 to move on the machine tool body 1 through the hydraulic push rod 212, and push the stamping lower die 211 out of the machine tool body 1, so that the staff can place the sheet metal raw materials on the machine tool body 1, and then retract the stamping lower die 211 into the machine tool body 1, and then retract the hydraulic telescopic wheel 222 to avoid crushing the hydraulic telescopic wheel 222 during sheet metal stamping. In the second step, the adjusting screw 242 is rotated to drive the adjusting moving block 241 to move the most on the machine tool body 1, so that the clamping fixed plate 233 is adjusted according to the width of the sheet metal, and then the clamping fixed plate 233 is driven downward by the contraction of the hydraulic telescopic rod 232. Clamping, clamping the sheet metal placed on the stamping lower die 211 to prevent it from shaking and displacing during stamping. The third step is that when clamping the sheet metal, the infrared rangefinder 34 will send a signal upward to detect the position of the clamping fixing plate 233, so as to judge the thickness of the sheet metal, and then transmit the signal to the stamping controller 35, which controls the stamping force of the stamping spindle 32. The thicker the sheet metal, the greater the stamping force. The fourth step is to start the stamping spindle 32 and make it operate downward, driving the stamping die 33 to stamp the sheet metal raw material on the stamping lower die 211 downward. After the stamping is completed, the material taking top plate 252 is driven by the telescopic material taking top rod 251 to lift the stamped sheet metal from the stamping lower die 211, so that the staff can take and place the stamped sheet metal, thus completing the use of a stamping device for precision sheet metal processing.
