[0026] An outer ring blade ring 11 is fixedly installed at the lower end of the frustum 2, an inner ring blade ring 12 is fixedly installed at the lower end of the frustum 2, a metal spring 13 is fixedly installed at the lower end of the frustum 2, a limiting column head 14 is fixedly installed at the lower end of the metal spring 13, the inner ring blade ring 12 is located on the inner side of the outer ring blade ring 11, the inner ring blade ring 12 and the outer ring blade ring 11 are arranged concentrically, which is convenient for synchronous trimming of the inner and outer rings, high work efficiency and neat trimming.
[0027] Specific working principle:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the trimming machine for rubber seal is used, the rubber seal to be trimmed is placed on the inner side of the annular steel seat 19. The size and width of the inner side of the annular steel seat 19 are the same as those of the rubber seal ring, so that the rubber seal can be quickly and accurately placed in the trimming position. After the placement is completed, the cylinder 18 on the support frame 17 drives the round table 2 to move downward. When the round table 2 moves downward, it drives the outer ring blade ring 11, the inner ring blade ring 12 and the limit column head 14 to move downward. The limit column head 14 first contacts the rubber seal, and the limit column head 14 contacts the rubber seal. The column head 14 continues to move downward to limit the rubber seal, the outer ring blade ring 11 and the inner ring blade ring 12 continue to move downward, the metal spring 13 is compressed, and when the outer ring blade ring 11 and the inner ring blade ring 12 contact the outer ring and inner ring of the rubber seal, the trimming begins, the outer ring blade ring 11 and the inner ring blade ring 12 have sharp edges, the outer ring blade ring 11 corresponds to the outer ring of the annular steel seat 19, and the inner ring blade ring 12 corresponds to the inner ring of the annular steel seat 19, and the real rubber seal is stuck between the inner ring and the outer ring of the annular steel seat 19, and then The outer blade ring 11 and the inner blade ring 12 cut off the scraps and contact the annular steel seat 19 to complete the cutting. The cut scraps fall on the upper side of the middle disc 9 and the outer ring 10. Then the cylinder 18 drives the round table 2 to move downward and lift it up, and the rubber seal inside the annular steel seat 19 is taken out. The first electric telescopic rod 7 drives the middle disc 9 and the outer ring 10 to move upward to the height flush with the upper surface of the workbench 1 through the connecting rod 8. The second electric telescopic rod 16 drives the push plate 3 and the push tooth 15 to move to the right, and the middle disc 9 and The rubber scraps on the upper side of the outer ring 10 are pushed to the inner side of the collection box 5 on the lower side of the waste inlet 4. Due to the characteristics of the rubber sealing ring production, the cut rubber scraps are mostly complete irregular pieces, which are easy to push. If there are individual fragments that are not easy to clean, the staff can manually pinch them out, and then the second electric telescopic rod 16 drives the push plate 3 and the push tooth 15 to move to the left and retract. The above completes a series of operations of the trimming machine for the rubber seal. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
