After the drilling is completed, the No. 2 cylinder 11 drives the pressing block 9 to move up and reset, and the No. 1 cylinder 8 drives the blank 101 to move down, bringing the blank 101 to the position of the make way port 5, and then unloading and grinding are carried out in sequence;

[0069] The lower end surface of the pressing block 9 presses the blank 101 firmly into the recess 6, and then drives the drilling assembly. The drilling motor 13 drives the drill rod 14 to rotate at high speed. At the same time, the No. 3 motor drives the drilling motor 13 to move downward. The high-speed rotating drill rod 14 drills a binding hole at the protruding position of the blank 101. Then the No. 2 cylinder 11 drives the pressing block 9 and the drilling assembly to move upward and reset; the pressing block 9 presses the blank 101 tightly, and then drills, ensuring the stability of the drilling process, so that the processed binding holes are more regular;

[0070] Each blank 101 is pushed onto the loading plate 15, and then the blanks 101 are pushed along the inlet 3 one by one and fall into the upper end surface of the column 2. The shape of the two sides of the loading plate 15 can prevent the blanks 101 from being stacked up and down during the pushing process;

[0071] The outer diameter of the pressing block 9 is smaller than the inner diameter of the limiting ring 21, so that the pressing block 9 can move up and down smoothly without interfering with the limiting ring 21, and the edge diameter of the stamped blank 101 is larger than the inner diameter of the limiting ring 21. Therefore, after the pressing block 9 moves up, the protrusion at the lower end of the pressing block 9 may be embedded in the protrusion of the blank 101 after stamping, which may drive the blank 101 to move up. However, under the constraint of the limiting ring 21, the limiting ring 21 blocks the blank 101, so that the blank 101 falls into the upper end position of the column 2 again.

[0072] After the drilling is completed, the drilling motor 13 moves up and retreats to reset, and then the No. 2 cylinder 11 drives the pressure block 9 and the drilling assembly to move up and reset, and then drives the No. 1 cylinder 8 to drive the column 2 to move down, and the column 2 drives the blank 101 to move down. The outer ring diameter of the column 2 is smaller than the inner ring diameter of the limit strip 20, ensuring that the column 2 can move up and down and will not interfere with the limit strip 20. At the same time, the outer edge diameter of the blank 101 after stamping is larger than the inner ring diameter of the limit strip 20. Therefore, when the upper end surface height of the column 2 is lower than the upper surface height of the limit strip 20, the edge of the blank 101 can be erected on the limit strip 20, and then the blanking assembly is driven, the No. 4 cylinder 16 drives the connecting plate 17 to approach the sleeve 1, and the push rod 18 drives the push block 19 to move into the clearance port 5, and pushes the blank 101 on the limit strip 20 away from the sleeve 1 along the outlet 4, and pushes it toward the grinding assembly;

[0073] After being pushed to the grinding assembly position, the No. 4 cylinder 16 drives the connecting plate 17 to reset, and the push rod 18 and the push block 19 are also reset, and then the No. 1 cylinder 8 pushes the column 2 up and resets it, and then the material is loaded;

[0074] A sprocket is provided at the lower end of each grinding wheel 25, which cooperates with an external chain to drive the multiple grinding wheels 25 to rotate, and the grinding wheels 25 in the two slide grooves 24 rotate in the same direction; after the push block 19 pushes the blank 101 onto the support plate 23, the edge of the blank 101 contacts the grinding wheel 25, and the edge of the blank 101 is embedded in the grinding part 26. At the same time, the grinding wheels 25 rotating in the same direction can drive the blank 101 to rotate, that is, the blank 101 is pushed by the push block 19 to make a linear motion, and at the same time, the blank 101 is rubbed by the multiple grinding wheels 25 to make a rotational motion. The blank 101 rotates and grinds, so that the entire edge of the blank 101 can be polished to eliminate burrs. At the same time, the grinding belt 27 provided can grind and clean the burrs on the lower surface of the protruding part of the blank 101;

[0075] During stamping and drilling, as well as the subsequent grinding process, the processing quality of the button can be improved by replenishing lubricating oil from the oil injection assembly, while extending the service life of the trouser button forming mold; the interior of the ring body 28 is hollow, and the ring body 28 is connected to the external oil pump through an oil pipe. The oil pump pumps the lubricating oil into the ring body 28, and then sprays it on the surface of the column 2 along the nozzle 29. When there is a blank 101 on the surface of the column 2, the lubricating oil is sprayed on the surface of the blank 101. The outer ring of the ring body 28 is also provided with a nozzle 29. On the one hand, the lubricating oil can be sprayed on the loading plate 15, so that the lower surface of the blank 101 can also be fully adhered to the lubricating oil, and in the subsequent stamping process, the wear between the blank 101 and the recess 6 is reduced. On the other hand, the blank 101 is slidably connected to the loading plate 15 through the lubricating oil, so that the pushing and loading of the blank 101 in the later stage is smoother;

[0076] The annular groove 30 and the notch 31 are provided to protect the external oil pump. If the pressing block 9 is embedded in the sleeve 1, the surface of the pressing block 9 blocks the end of the nozzle 29, which will cause the oil circuit pressure to rise and affect the normal operation of the oil pump. For this reason, the annular groove 30 and the notch 31 are provided. When the pressing block 9 is embedded in the sleeve 1, the end of the nozzle 29 is opposite to the annular groove 30. At this time, the lubricating oil can be smoothly sprayed out and flow out along the notch 31, so that the lubricating oil pressure is in a stable state.

[0077] When the push block 19 moves toward the yield opening 5, the blank 101 is pushed to the grinding assembly position. When the push block 19 retreats and resets, the connecting plate 17 retreats and squeezes the No. 1 piston cylinder 32. The No. 1 piston cylinder 32 pushes the hydraulic oil in the No. 1 piston cylinder 32 to the No. 2 piston cylinder 34 through the oil guide pipe 37. At this time, the No. 2 piston rod 35 is gradually pushed out and pushes the blank 101 on the conveyor belt toward the upper material plate 15 to prepare the blank 101. The No. 2 piston rod 35 extends each time by a length equal to the diameter of a blank 101, and can accurately push each blank 101 to the upper end surface position of the column 2 in sequence.

[0078] When the material unloading action is performed, the connecting plate 17 moves toward the direction of the sleeve 1, and the connecting plate 17 no longer squeezes the No. 1 piston rod 33. At this time, the No. 1 piston rod 33 is pushed out under the elastic force of the spring connected to it, and the hydraulic oil in the No. 2 piston cylinder 34 is pumped into the No. 1 piston cylinder 32, and the No. 1 piston rod 33 also retreats and resets.
