[0029] When the present embodiment is used, by setting the connecting assembly 2, when the die 1 is installed, the pull plate 26 is pulled to drive the slide bar 25 and the limit plate 27 to slide in the fixed cylinder 21, and the spring 28 is compressed. Then the die 1 can be placed on the die 2 1, and the plug plate 22 at the lower end of the die 1 4 is inserted into the slot 23 at the upper end of the die 2 1, and the pull plate 26 is released. The spring 28 is stretched to push one end of the slide bar 25 into the clamping hole 24 of the plug plate 22, so as to achieve the effect of limiting and fixing the plug plate 22 and the die 1 4. Pulling the pull plate 26 can drive one end of the slide bar 25 to move out of the clamping hole 24, so that the die 1 can be fixed. 4 is removed from the concave die 1, and the connection component 2 is provided to facilitate the disassembly and cleaning of the concave die 4, so as to avoid the brake pad friction powder from being easily spilled to the upper end of the concave die 4 when adding the brake pad friction powder into the concave die 4.

[0030] By adopting the above technical solution, when the upper cover plate 5 is lifted or lowered, the I-shaped wheels 33 at one end of the cross plates 32 at both ends of the upper cover plate 5 slide in the sliding grooves 34 of the fixed frame 31. The sliding of the I-shaped wheels 33 in the sliding grooves 34 of the fixed frame 31 can play a guiding role in the lifting and lowering of the upper cover plate 5, so that the lifting and lowering of the upper cover plate 5 is more stable. Triangular support plates 35 are fixed at both ends between the cross plates 32 and the upper cover plate 5 to make the connection between the cross plates 32 and the upper cover plate 5 more firm.

[0031] In the present invention, further, the side of the I-shaped wheel 33 is in close contact with the inner wall of the sliding groove 34. The fixed frame 31 and the second die 1 as well as the cross plate 32 and the upper cover plate 5 are welded by spot welding.

[0032] By adopting the above technical solution, the sliding of the I-shaped wheel 33 in the sliding groove 34 is more stable, and the spot welding makes the connection between the fixed frame 31 and the second die 1 as well as the cross plate 32 and the upper cover plate 5 more firm.

[0033] When this embodiment is in use, by setting the guiding assembly 3, when the upper cover plate 5 is lifted or lowered, the I-shaped wheels 33 at one end of the cross plates 32 at both ends of the upper cover plate 5 slide in the sliding grooves 34 of the fixed frame 31. The sliding of the I-shaped wheels 33 in the sliding grooves 34 of the fixed frame 31 can play a guiding role in the lifting and lowering of the upper cover plate 5, so that the lifting and lowering of the upper cover plate 5 is more stable. Triangular support plates 35 are fixed at both ends between the cross plates 32 and the upper cover plate 5 to make the connection between the cross plates 32 and the upper cover plate 5 more firm.

By setting the die 14 and the like, energy consumption is reduced and the manual workload is reduced, thereby reducing costs. By setting the connecting component 2, when the die 14 is installed, the pull plate 26 is pulled to drive the slide bar 25 and the limit plate 27 to slide in the fixed cylinder 21, and the spring 28 is compressed. Then the die 14 can be placed on the die 21, and the plug plate 22 at the lower end of the die 14 is inserted into the slot 23 at the upper end of the die 21. The pull plate 26 is released, and the spring 28 is stretched to push one end of the slide bar 25 into the card hole 24 of the plug plate 22, and the die 14 is pressed. The insert plate 22 and the die 1 are limited and fixed to each other. Pulling the pull plate 26 can drive one end of the slide bar 25 to move out of the clamping hole 24, so that the die 14 can be removed from the die 21. The connection component 2 is provided to facilitate the disassembly and cleaning of the die 14, so that when adding brake pad friction powder to the die 14, the brake pad friction powder is easily spilled to the upper end of the die 14. The brake pad friction powder is easily accumulated on the upper end of the die 14 after long-term use, and it is difficult to clean. By providing the limit component 29, when there is no need to pull the pull plate 26, the pull plate 26 can pass through the through groove 293 through the rotating plate 292, and the rotating plate 292 is turned. The plate 292 can be rotated to a vertical state at one end of the die 21 by the rotating rod 291. The rotating plate 292 can limit the pull plate 26 to avoid pulling the pull plate 26 by mistake. By setting the guide component 3, when the upper cover plate 5 is lifted or lowered, the industrial wheel 33 at one end of the cross plate 32 at both ends of the upper cover plate 5 slides in the slide groove 34 of the fixed frame 31. The sliding of the industrial wheel 33 in the slide groove 34 of the fixed frame 31 can guide the lifting of the upper cover plate 5, thereby making the lifting of the upper cover plate 5 more stable. The triangular support plates 35 are fixed at both ends between the cross plate 32 and the upper cover plate 5 to make the cross plate 32 and the upper cover plate 5 more secure.
