After the stamping is completed, the lifting piece 5 lifts the gasket in the stamping groove 31 to the table surface of the lower stamping die 3. At this time, the pushing cylinder 41 on one side drives the pushing plate 42 to push the gasket along the unloading platform 13 to the receiving box 14 on one side for collection.

[0037] Reference Figure 1 and Figure 2 A limit baffle 33 is vertically arranged on the upper side of the lower stamping die 3 and on the opposite sides in the length direction. The push plate 42 slides along the limit baffle 33. When the push plate 42 slides and pushes the gasket to move, the limit baffle 33 blocks the gasket on the lower stamping die 3, and the gasket is not easy to fall off when sliding.

[0038] Reference Figure 2 and Figure 3 The lower stamping die 3 is provided with a sliding groove 34 at the lower side of the stamping groove 31. The lifting member 5 includes a sliding plate 51 and a pushing block 52. The sliding plate 51 is horizontally arranged. The sliding plate 51 is vertically slidably installed at the sliding groove 34 of the lower stamping die 3. The pushing block 52 is arranged on the upward side of the sliding plate 51, and the upward side of the pushing block 52 is located on the downward side of the stamping groove 31 of the lower stamping die 3.

The upper end of the spring 36 is connected to the lower side of the sliding plate 51. When the sliding plate 51 is pushed to slide, the spring 36 is stretched. At this time, the pushing block 52 pushes the gasket out. When the sliding plate 51 returns to its original position, the spring 36 drives the sliding plate 51 to the limit block 511 on one side and presses against the adjusting plate. The sliding plate 51 is not easy to shake during the stamping operation.

[0043] The implementation principle of a processing device for a sample injection spacer in an embodiment of the present application is as follows: the hydraulic cylinder 12 drives the upper stamping die 2 to move to the lower stamping die 3 for stamping, and drives the upper stamping die 2 to return after the stamping operation is completed. At this time, the driving cylinder 61 drives the push plate 62 to slide upward, and the push block 52 on the push plate 62 pushes the gasket from the stamping groove 31 to the table surface of the lower stamping die 3. At this time, the pushing cylinder 41 on one side drives the pushing plate 42 to push the gasket to the receiving box 14 on one side for collection.
