[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] In this embodiment, Figures 1 to 4 As shown, it includes a punching machine body 1, which includes a machine body and operating parts located in the machine body. The machine body includes a base and a fixed frame arranged on the base. A hydraulic telescopic structure 2 is provided on the fixed frame. A stamping structure 3 is provided at the lower end of the hydraulic telescopic structure 2. The fixed frame is provided with a blowing structure 4 for blowing downwards on both sides of the stamping structure 3. The fixed frame is provided with through holes on both sides of the stamping structure 3. The blowing structure 4 includes an air duct, which can be a telescopic corrugated pipe. The top of the air duct passes through the through hole and extends into the fixed frame. A fan structure connected to the top of the air duct is provided in the fixed frame. A wind cover 13 is provided at the bottom end of the air duct. Since the air duct is a corrugated pipe, the position of the wind cover 13 can be adjusted at will. When the blowing structure 4 is not used, the air duct only needs to be inserted into the fixed frame from top to bottom, leaving only the wind cover 13 exposed. At this time, the outer periphery of the wind cover 13 has an external thread, and the inner wall of the through hole has an internal thread. When the air duct is collected in the fixed frame, the wind cover 13 is threadedly connected to the through hole.

[0021] The hydraulic telescopic structure 2 includes a telescopic fixed column, and a stamping structure 3 is provided at the lower end of the fixed column. The stamping structure 3 is mainly a stamping head. The driving parts that drive the fixed column to telescope and the stamping head to work are all located in the fixed frame and will not be described here.

[0022] A stamping base 5 is provided directly below the stamping structure 3, and a cavity 6 with an opening facing upward is provided at the bottom of the base of the punch body 1. The stamping base 5 is located in the center of the cavity 6. The stamping base 5 is in the shape of a quadrangular pyramid with a small top and a large bottom. The top of the stamping base 5 extends out of the opening of the cavity 6, that is, the height of the stamping base 5 is higher than the opening of the cavity 6. The top surface of the stamping base 5 is a stamping surface 7, and the stamping surface 7 faces the stamping head above. A cover plate 8 is provided at the opening of the cavity 6. A avoidance hole 9 is provided in the center of the cover plate 8 for the top of the stamping base 5 to pass through. The cover plate 8 is a grid plate structure. During the stamping process, the debris and waste generated by the stamping are blown from top to bottom by the blowing structure 4, so that the debris and waste on the stamping surface 7 fall onto the cover plate 8, and then fall into the cavity 6 through the grid of the cover plate 8. The setting of the grid cover plate 8 can also prevent the debris and waste in the cavity 6 from running out of the cavity 6, thereby playing a certain blocking role.

[0023] Waste collecting devices 10 are provided on both sides of the base, that is, the waste collecting devices 10 are provided on the same side as the blowing structure 4. The waste collecting devices 10 include a box body 11 fixed to the outside of the base. The box body 11 has a mounting hole on the side. The mounting hole is connected to the cavity 6. The mounting hole is located at the bottom of the box body 11 and is rectangular. A suction structure is provided in the box body 11. The suction structure includes a suction fan. The suction fan is provided with a channel between the mounting holes. One end of the channel is connected to the cavity 6 through the mounting hole, and the other end is connected to the suction fan. The suction fan works The debris and waste that falls into the cavity 6 is sucked away. Since the outer wall of the stamping base 5 is inclined, the debris and waste that falls into the cavity 6 will naturally fall along the outer wall of the stamping base 5 without accumulating on the outer wall of the stamping base 5. The debris and waste that falls into the bottom of the cavity 6 can be sucked away in time by the waste collecting device 10. Since the waste collecting device 10 is located on both sides of the stamping base 5 and is arranged on the same side as the blowing structure 4, the debris and waste blown off by the blowing structure 4 can fall into both sides of the stamping base 5, just fall in front of the mounting hole, and then be directly sucked away by the suction fan.

[0024] A partition net 12 is provided between the side of each box body 11 and the cavity 6, that is, a partition net 12 is provided between the mounting hole and the cavity 6, which can prevent larger materials or debris accidentally dropped from the stamping surface 7 from directly entering the waste collection device 10. At the same time, it can also prevent the waste in the waste collection device 10 from returning to the cavity 6 to a certain extent, thereby isolating the waste.

[0025] It should be noted that the stamping base 5 and the inner wall of the cavity 6 are designed as an integral whole, and a distance is left between the bottom edge of the stamping base 5 and the inner wall of the cavity 6, so that the bottom edge of the stamping base 5 and the inner wall of the cavity 6 are connected by a transition surface 15, and the transition surface 15 is inclined downward toward the inner wall of the cavity 6. When debris and waste fall into the bottom of the cavity 6, they can directly pass through the partition net 12 along the transition surface 15 and enter the mounting hole, so that debris and waste will not accumulate at the bottom of the cavity 6.

[0026] The blowing structure 4 is located on both sides of the stamping structure 3, so that the blowing structure 4 blows away the debris generated by the stamping structure 3 from top to bottom, so that the debris waste generated by the stamping structure 3 is directly blown to the front of the mounting hole in the cavity 6, which is convenient for the waste collection device 10 to absorb. At the same time, the blowing structure 4 can also blow air to cool the stamping head and the stamping surface 7.

[0027] The punch body 1 is provided with transparent windshields 14 on both sides of the punch base 5, so that the air blowing structure 4 can blow along the windshields into the cavity 6 instead of blowing outward to the side.

[0028] The cover plate 8 is detachably arranged, and a protrusion is arranged on the inner wall of the cavity 6 , and the cover plate 8 is directly stuck on the protrusion, so that the cover plate 8 can be detachably covered, which is convenient for cleaning the inside of the cavity 6 .

[0029] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
