[0028] When in use, place the plate on the die 11, press the two start buttons on the cabinet 1 to start the hydraulic rod 13, the hydraulic rod 13 pushes the fixed plate 14 to move downward, so that the punch 15 squeezes the plate downward, and the workpiece and the waste edge are separated by the stripping assembly, and the formed workpiece falls into the groove of the die 11, then the hydraulic rod 13 is lifted, and the waste edge is blown away by the blowing assembly, and the waste edge is removed from the die 11, then the stripping assembly pushes the workpiece out, and then the workpiece is removed, and the plate is placed again to continue processing, which optimizes the production process and eliminates the process of manually separating waste and formed workpieces. Example

[0029] On the basis of Example 1, a mounting plate 2 is fixedly connected between the inner walls of the cabinet 1, a hydraulic cylinder 21 is fixedly installed on the top of the mounting plate 2, a hydraulic station 22 is provided under the mounting plate 2, a push rod 23 is fixedly installed on the top of the hydraulic cylinder 21, a material return core 24 is provided inside the groove of the die 11, and through holes 25 are respectively provided at the bottom of the groove of the die 11 and the top of the cabinet 1. The two through holes 25 are connected to the interior of the cabinet 1, and the top of the push rod 23 passes through the two through holes 25 and extends to the inside of the groove of the die 11. The top of the push rod 23 is connected to the material return core 24.

[0030] When the punch 15 punches downward, the hydraulic station 22 controls the hydraulic cylinder 21 to retract downward, and drives the material stripping core 24 to move downward through the push rod 23. The push rod 23 moves inside the two through holes 25, and the material stripping core 24 moves to the bottom and fits the bottom of the groove of the die 11 and stops working. The punch 15 punches the workpiece out and drops it into the groove of the die 11, and the waste material remains on the die 11, thereby separating the waste edge from the workpiece. The waste edge is then removed, and the hydraulic rod 13 is lifted to drive the punch 15 to move upward. The punch 15 is separated from the die 11, and then the hydraulic station 22 controls the hydraulic cylinder 21 to push out again, and drives the material stripping core 24 to move upward through the push rod 23 to push the workpiece out of the groove, thereby eliminating the need for manual separation and saving the cost of use. Example

[0031] On the basis of Example 1, an air cylinder 3 is provided inside the mounting frame 12, a compression block 31 is provided inside the air cylinder 3, a connecting rod 32 is fixedly connected to the top of the compression block 31, the top of the connecting rod 32 passes through the air cylinder 3 and extends to the outside, a blowing plate 33 is fixedly installed on one side of the upper surface of the die 11, and an air outlet nozzle 34 with an acute angle structure is provided on the side of the blowing plate 33 close to the die 11, an air outlet hole 35 and an air inlet hole 36 are provided on the top of the air cylinder 3, and the air outlet hole 35 and the air inlet hole 36 are both A one-way valve 37 is provided, and the flow directions of the two one-way valves 37 are opposite. An air supply pipe 38 is fixedly connected to the top of the air outlet 35. One end of the air supply pipe 38 is communicated with the internal cavity of the blowing plate 33. An exhaust port 39 is provided on the side of the air cylinder 3 near the bottom end. A slide groove 310 is provided on the front side of the mounting frame 12 opposite to the air cylinder 3. A slider 311 is provided inside the slide groove 310. One end of the slider 311 is connected to the fixed plate 14, and the other end of the slider 311 is connected to the connecting rod 32.

[0032] During stamping, the fixed plate 14 moves downward, driving the slider 311 to move inside the slide groove 310, and the slider 311 drives the connecting rod 32 to move, and the compression block 31 is driven downward inside the air cylinder 3 by the connecting rod 32. The compression block 31 squeezes out the air below, discharges it through the exhaust port 39, and then discharges it to the outside from the slide groove 310. The compression block 31 moves downward to generate negative pressure to suck open the one-way valve 37 inside the air inlet 36, and the one-way valve 37 inside the air outlet 35 is closed, and the outside air enters the air cylinder 3 from the air inlet 36. After the stamping is completed, the fixed plate 14 moves upward, and the compression block 31 is driven upward according to the above principle. The compression block 31 moves upward to compress the air sucked into the air cylinder 3. Under the action of pressure, the one-way valve 37 inside the air inlet 36 is closed, and the one-way valve 37 inside the air outlet 35 is opened. The air is discharged from the air outlet 35 into the air supply pipe 38, and is transported to the cavity inside the blowing plate 33 through the air supply pipe 38, and then blown out from the air outlet nozzle 34. Since the air outlet nozzle 34 is in an acute angle shape, the inlet is wide and the outlet is narrow, the air is compressed and accelerated again, so that the blown gas has a strong wind force. The blown wind is aimed at the waste, and then the waste is blown away from the die 11, and then it can be processed again, thereby improving work efficiency. Example

[0033] On the basis of Example 1, a connecting plate 4, a protective cover 41 and a bottom plate 42 are respectively sleeved on the outside of the punch 15. The top of the connecting plate 4 is connected to the fixed plate 14. A plurality of springs 43 are connected between the bottom of the fixed plate 14 and the protective cover 41. The bottom plate 42 is located inside the protective cover 41. Four equally spaced mounting holes 44 are provided on the top of the fixed plate 14. Sockets 45 corresponding to the four mounting holes 44 are provided on the connecting plate 4. Bolts 46 are provided between a pair of opposite mounting holes 44 and the inside of the sockets 45. The bottom end of the bolt 46 passes through the protective cover 41 and is threadedly connected to the bottom plate 42.

[0034] After startup, the hydraulic rod 13 drives the fixed plate 14 and the punch 15 to move downward. Since the fixed plate 14 is connected to the base plate 42 by bolts 46, the movement of the fixed plate 14 will also drive the base plate 42 to move downward. The protective cover 41 is always in contact with the base plate 42 under the action of the spring 43, and then the base plate 42 will drive the protective cover 41 to move downward. First, the bottom of the protective cover 41 contacts the top of the die 11, covering the processing area to prevent debris from splashing. As the hydraulic rod 13 continues to move, the protective cover 41 squeezes the spring 43, and the punch 15 punches the plate downward.
