A bottom pad 11 is fixedly installed in the middle of the top outer surface, and a second spring 101 is fixedly installed at the bottom end of the bottom pad 11. A buffer layer 12 is provided at the inner upper end of the workbench 6, and a buffer sleeve 121 is fixedly installed in the middle of the buffer layer 12. A guide layer 13 is provided at the inner lower end of the workbench 6, and a guide plate 131 is fixedly installed on the right side wall of the guide layer 13. A collecting bin 14 is movably installed on the left side of the base 1, a handle 15 is fixedly installed on the left top end of the collecting bin 14, a universal wheel 151 is movably installed on the left end of the bottom side of the collecting bin 14, and a positioning block 16 is fixedly installed on the top of the right outer surface of the collecting bin 14.

[0025] In the embodiment of the utility model, the number of the shock absorbing blocks 3 is 3, and the shock absorbing blocks 3 are evenly distributed at the bottom end of the bottom plate 4, so as to reduce the vibration of the device during use.

[0026] In the embodiment of the utility model, the first spring 10 and the second spring 101 are made of alloy spring steel with high elastic limit and fatigue resistance to ensure that the springs have sufficient elastic deformation capacity and can withstand a large load.

[0027] In the embodiment of the utility model, the pressure pad 8, the base pad 11 and the buffer sleeve 121 are penetrated from top to bottom in the center. The inner diameters of the pressure pad 8 and the base pad 11 are the same. The inner diameter of the buffer sleeve 121 is larger than the inner diameter of the base pad 11 to facilitate quick punching, prevent displacement, and reduce the time that waste stays inside the device.

[0028] In the embodiment of the utility model, the left side of the bottom plate 4 is in an arc shape, and the guide plate 131 passes through the left end of the workbench 6 and forms a slope with the bottom plate 4 to guide the waste to fall into the collection bin 14.

[0029] In the embodiment of the utility model, the top of the right side of the collecting bin 14 is a slope with the right side higher and the left side lower, so as to prevent waste from being accumulated on the top of the collecting bin 14 .

[0030] In the embodiment of the utility model, the positioning block 16 can be movably installed between the bottom plate 4 and the top of the operating table 2. The height of the positioning block 16 is lower than the height of the shock-absorbing block 3, so that the collection bin 14 is placed in an accurate position for waste collection.

[0031] Working principle: During the use of the punching machine for metal stamping, the punching material is placed on the top of the base pad 11. When the punching head 7 descends, the pressure pad 8 first fixes and presses the material on the top of the base pad 11 to prevent displacement during punching. After the first spring 10 and the second spring 101 are compressed respectively, the punching rod 9 descends to contact the material at the bottom. After the bottom end of the base pad 11 abuts against the top of the buffer sleeve 121, the punching rod 9 punches downward, and the waste falls out of the base pad 11 and passes through the buffer sleeve 121. , enters the guide layer 13, and falls into the collecting bin 14 along the inclined surface of the guide plate 131. The collecting bin 14 is placed in a fixed position before the punching operation to collect the generated waste in time. After punching, the punching rod 9 starts to rise, and the first spring 10 and the second spring 101 start to rebound, and the bottom pad 11 rises with the material. After the punching rod 9 does not contact the material, the bottom pad 11 rises to the initial height, and the pressure pad 8 finally releases the material to avoid deformation after punching during the process and avoid unnecessary material loss.
