[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 of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a sheet metal stamping die, comprising: a bottom plate 100, a cover plate 300 and a buffer assembly, a feeding assembly 200 is installed on the upper surface of the bottom plate 100, a column 120 is installed at each of the four corners of the upper surface of the bottom plate 100, a cover plate 300 is installed at one end of the column 120 away from the bottom plate 100, a pneumatic pump 310 is installed on the upper surface of the cover plate 300, and a pressing plate 310 is installed on the lower surface of the cover plate 300. 20. A buffer assembly is installed above the base plate 100 through the column 120. The buffer assembly includes: a buffer plate 400 for installing a buffer spring 410, and a buffer spring 410. A plurality of buffer springs 410 are evenly installed on the upper surface of the buffer plate 400. The feeding assembly 200 includes a mounting plate 210 and a baffle plate 220. A baffle plate 220 is installed on the upper surface of the mounting plate 210. A plurality of rollers 211 are evenly installed on the upper surface of the mounting plate 210.

[0021] See also Figure 1 , Figure 3As the first embodiment of the utility model: the center position of the upper surface of the bottom plate 100 is provided with an inclined groove 101 at an angle of 15 degrees, which is lower in front and higher in the back. The front surface of the inclined groove 101 is hinged with a door panel 110. The center positions of the left edge and the right edge of the upper surface of the bottom plate 100 are provided with mounting plates 210. The upper surfaces of the two mounting plates 210 are symmetrically provided with baffles 220.

[0022] When in use, the user first feeds the sheet metal to the bottom of the stamping die 420 through the feeding assembly 200, and then starts the pneumatic pump 310. When the pneumatic pump 310 is working, the telescopic end of the pneumatic pump 310 will penetrate the upper surface of the cover plate 300, causing the pressure plate 320 to move downward, thereby causing the pressure plate 320 to drive the stamping die 420 on its lower surface to move, thereby performing a stamping operation on the sheet metal through the stamping die 420. When the pressure plate 320 moves downward, the compression spring will be compressed. At this time, the buffer spring 410 inside the buffer assembly can reduce the impact on the stamping die 420 and extend its service life. At the same time, it helps to maintain a stable stamping process and reduce the scrap rate. When the telescopic end of the pneumatic pump 310 is retracted, the pressure plate 320 will slowly return to its original position, thereby causing the compressed spring to slowly retract and restore its deformation, and then the stamping operation on the next side can be performed.

[0023] See also Figure 1 , Figure 2 As a second embodiment of the utility model: a gap is provided between the two baffles 220, a plurality of rollers 211 are evenly installed on the upper surface of the mounting plate 210 at the gap between the two baffles 220, a buffer plate 400 is installed above the feeding assembly 200 through the column 120, a circular through hole is opened in the center of the buffer plate 400, and four buffer springs 410 are evenly installed on the upper surface of the buffer plate 400;

[0024] One end of the buffer spring 410 away from the buffer plate 400 is connected to the lower surface of the pressing plate 320. The center of the lower surface of the pressing plate 320 is installed with the stamping die 420. The central axis of the lower end of the stamping die 420 is aligned with the gap between the two baffles 220. The width of the pressing plate 320 is the same as the width of the cover plate 300.

[0025] A pneumatic pump 310 is installed at the center of the upper surface of the cover plate 300, and the telescopic end of the pneumatic pump 310 penetrates the upper surface of the cover plate 300 and is connected to the upper surface of the pressing plate 320;

[0026] When in use, the user can prepare the sheet metal to be stamped (the width of the sheet metal must not be greater than the spacing between the two baffles 220, so that the sheet metal is between the two baffles 220), and then contact the lower surface of the sheet metal with the roller 211 above the right-hand mounting plate 210 on the upper surface of the bottom plate 100, and then the sheet metal moves toward the roller 211 on the surface of the other mounting plate 210 through the roller 211. After contact, the user can now perform the stamping operation according to the operating steps of the previous embodiment, and the stamped sheet metal falls back into the inclined slot 101. Then the user opens the door panel 110 of the inclined slot 101 to collect the impacted sheet metal. The user can use the feeding assembly 200 to conveniently and quickly deliver the sheet metal to the bottom of the stamping die 420, thereby reducing manual operation time and ensuring that the sheet metal is accurately placed under the die, thereby improving the accuracy of stamping and reducing the workload of the operator.
