[0023] The utility model will be further explained according to the drawings.

[0024] For example Figures 1 to 6The diameter reducing and shaping clamp comprises a base 1, a product positioning module 2, a diameter reducing halo 3, a shaping component 4 and an outer cover 5, two vertical supports 19 are arranged at the left and right ends of the base 1, the upper ends of the two vertical supports 19 are respectively fixed with infrared sensors 20 for measuring whether the product placement position is correct, the upper end of the base 1 is fixed with the product positioning module 2 through a bolt, the product positioning module 2 is provided with a positioning pin 17, the upper end of the product positioning module 2 is provided with the shaping component 4, the bottom end of the shaping component 4 is a pressing head 8, a supporting column 7 is arranged above the pressing head 8, a spring 1 6 is arranged on the outer side of the upper part of the supporting column 7, the outer cover 5 is arranged above the base, the diameter reducing halo 3 is arranged in the outer cover, and the diameter reducing halo 3 is composed of a plurality of halo blocks in the shape of a circular table. In the embodiment, 12 halo blocks are used, when the diameter reducing halo is subjected to an upward thrust from the lower side, the diameter reducing halo moves upward in the cover and the spring in the middle of the 12 halo blocks is squeezed, so that the inner diameter is gradually reduced. The shaping component 4 accurately positions the circular rubber metal piece, the product and the pressing head can be centered, and the outer sleeve position of the rubber metal piece can be uniformly shaped.

[0025] Four supporting columns are arranged in the middle of the base 1 for buffering the contact between the outer cover 5 and the base 1.

[0026] A recess is arranged in the center of the base 1, the shape of the recess is consistent with the shape of the bottom of the product positioning module 2, and the product positioning module 2 is better fixed.

[0027] The product positioning module 2 is provided with a groove 18, so that the product can rotate in the groove.

[0028] The upper part, the middle part and the lower part of the supporting column 7 are in the shape of a cylinder, the upper part has a smaller cross-sectional diameter than the middle part, and the middle part has a smaller cross-sectional diameter than the lower part.

[0029] The outer cover 5 is composed of multiple layers, the bottom layer is provided with a cover plate 15, the upper layer of the cover plate 15 is provided with a halo cover 14, the upper layer of the halo cover 14 is provided with a guide ring 13, the inner side of the guide ring 13 is provided with a guide head 12, the upper layer of the guide ring 13 is provided with a fixing seat 10, and the inner sides of the guide ring 13 and the fixing seat 10 are provided with springs 2 11.

[0030] The outer side of the halo cover 14 is provided with a connecting nut 2 16, and the upper surface of the fixing seat 10 is provided with a connecting nut 1 9.

[0031] The lower end of the guide head 12 is inwardly bent, and the lower end of the guide head 12 abuts against the side surface of the lower part of the supporting column 7, so that the guide head 12 and the supporting column 7 are better fixed.

[0033] In use, open the diameter reduction and shaping fixture, place the rubber and metal parts into the product positioning module 2 in the correct direction, and fix them with positioning pins 16; the hydraulic cylinder moves down, as... Figure 7 The shrinking part 3 first contacts the base 1 and then begins to compress the outer sleeve of the rubber-metal part, making the outer diameter smaller. At the same time, the pressure head 8 of the shaping component 4 and the upper end face of the rubber-metal part's outer sleeve are completely in contact, so that the end face of the rubber-metal part's outer sleeve begins to bear force, preventing the outer sleeve from arching and deforming upwards.
