[0026] Furthermore, the control assembly comprises a rectangular cylinder 204 fixed to the bottom of the processing table 101, a rectangular plate 205 slidably connected in the rectangular cylinder 204, one end of the rectangular plate 205 being fixed with a toothed plate 206, the toothed plate 206 being engaged with the gear 203, when the toothed plate 206 moves towards the rectangular cylinder 204, the one-way bearing 202 is locked, when the toothed plate 206 moves, the gear 203, the one-way bearing 202 and the rotating rod 201 rotate synchronously, when the rotating rod 201 rotates, the first mounting plate 102 rotates, when the toothed plate 206 moves away from the rectangular cylinder 204, the one-way bearing 202 is not locked, when the toothed plate 206 moves, the gear 203 and the outer ring of the one-way bearing 202 rotate, the inner ring of the one-way bearing 202 and the rotating rod 201 do not rotate, the moving plate 208 is provided with a first vertical slot 210, an inclined slot 211 and a second vertical slot 212, the two ends of the inclined slot 211 are communicated with the first vertical slot 210 and the second vertical slot 212 respectively, two lug plates 209 are fixed to the side of the rectangular plate 205 away from the toothed plate 206, and a cylindrical rod 213 is fixed between the two lug plates 209.
[0027] Initially, the cylindrical rod 213 is located at the bottom of the second vertical slot 212, when the hydraulic cylinder 107 is elongated, the second mounting plate 108 and the upper die 109 are lowered, so that the upper die 109 and the lower die 103 cooperate to stamp the product, in this process, when the hydraulic cylinder 107 is elongated, the first connecting plate 216 is lowered, when the first connecting plate 216 is lowered, the second connecting plate 218 and the moving plate 208 are lowered, when the moving plate 208 is lowered, the cylindrical rod 213 slides in the second vertical slot 212 to the inclined slot 211, and then slides from the inclined slot 211 to the first vertical slot 210, when the cylindrical rod 213 slides in the inclined slot 211, the cylindrical rod 213 is extruded to drive the rectangular plate 205 to move away from the moving plate 208, when the rectangular plate 205 moves, the toothed plate 206 moves, at this time, the one-way bearing 202 is not locked, so that the movement of the toothed plate 206 drives the gear 203 and the outer ring of the one-way bearing 202 to rotate, and the inner ring of the one-way bearing 202 and the rotating rod 201 do not rotate, that is, the first mounting plate 102 does not rotate, so that the upper die 109 can be lowered into the lower die 103 to complete the stamping of the product;
[0028] When the stamping is finished, the hydraulic cylinder 107 retracts to drive the second mounting plate 108 and the upper die 109 to move upwards. When the second mounting plate 108 moves upwards, the first connecting plate 216 moves upwards, and when the first connecting plate 216 moves upwards, the second connecting plate 218 and the moving plate 208 move upwards. During the movement of the moving plate 208, the cylindrical rod 213 first slides in the first vertical slot 210. When the cylindrical rod 213 slides from the top of the first vertical slot 210 to the bottom of the first vertical slot 210, the upper die 109 is separated from the lower die 103 by a certain distance. Then the moving plate 208 continues to move upwards, so that the cylindrical rod 213 slides in the inclined slot 211. At this time, the cylindrical rod 213 is extruded and drives the rectangular plate 205 and the tooth plate 206 to move towards the moving plate 208. At this time, the one-way bearing 202 is locked, so that when the tooth plate 206 moves, the gear 203, the one-way bearing 202, the rotating rod 201, and the first mounting plate 102 rotate synchronously. It should be noted that when the cylindrical rod 213 slides from the inclined slot 211 to the second vertical slot 212, the first mounting plate 102 rotates by one hundred and eighty degrees, so that the other lower die 103 rotates to be directly below the upper die 109. The lower die 103 after stamping is moved away from below the upper die 109. At this time, the finished product in the lower die 103 is taken out, and then the product to be stamped is placed. This process is not only safer, but also does not occupy the stamping time when taking out the finished product and placing the product to be stamped, thereby improving the work efficiency.
