When the height of the sleeve 40 is less than the height of the bottom of the first groove 37, the bottom of the rolled piece is supported on the first groove 37. When the height of the bottoms of the two alloy roller rings 19 is flush with the first groove 37, the bottom of the rolled piece is just subjected to the pressing treatment. When the height of the sleeve 40 is higher than the height of the bottom of the first groove 37, the rolled piece is supported in the first groove 37.

[0030] Working method and principle: When in use, the two alloy roller rings 19 are respectively sleeved on the expansion sleeves 18 of the first spindle 12 and the second spindle 13, and the hollow hydraulic cylinder 26 pushes the expansion sleeve 18 upward by 2mm, and the alloy roller ring 19 is manually put in from the top, and the hollow hydraulic cylinder 26 returns, and the disc spring 25 assembly pulls down the expansion sleeve 18, and the expansion sleeve 18 tightens the alloy roller ring 19 to complete the installation of the alloy roller ring 19. When disassembling, the hollow hydraulic cylinder 26 pushes the expansion sleeve 18 upward by 2mm, and the outer diameter of the expansion sleeve 18 will shrink when it is pushed out by 2mm, and the alloy roller ring 19 is manually taken out from the top. After the alloy roller ring 19 is installed, the screw rod 28 is driven to rotate by the roller gap adjustment motor 33. The rotation of the screw rod 28 drives the first internal thread block 31 and the second internal thread block 32 to move in the opposite direction. The first internal thread block 31 and the second internal thread block 32 drive the first slide plate 16 and the second slide plate 17 to move in the opposite direction. The first slide plate 16 and the second slide plate 17 drive the first spindle box 14 and the second spindle box 15 to move in the opposite direction. The first spindle box 14 and the second spindle box 15 drive the first spindle 12 and the second spindle 13 to move in the opposite direction, thereby finally making the alloy roller rings 19 on the first spindle 12 and the second spindle 13 approach or move away from each other, thereby realizing the adjustment of the roller gap. The lead screw is driven to rotate by the slot type selection motor 5 and the right-angle reducer 4, so that the lifting and lowering of the lifting plate 8 is realized through the cooperation of the lead screw and the lead screw pair nut. One side of the lifting plate 8 cooperates with the slide rail 7 of the first vertical plate 2 through the slider 10. Since the first spindle box 14 and the second spindle box 15 are respectively connected to the first slide plate 16 and the second slide plate 17, and the first slide plate 16 and the second slide plate 17 are respectively connected to the connecting plate 35 of the roll gap adjustment component, the first spindle 12 and the second spindle 13 are synchronously lifted and lowered with the lifting plate 8, so that the height difference from the bottom of the two alloy roll rings 19 to the bottom of the first groove 37 opened on the first vertical plate 2 is adjusted. When in use, the pressing piece passes between the two alloy roller rings 19, and the lower part is supported on the upper surface of the sleeve 40 or the upper surface of the bottom of the first groove 37. When the height of the sleeve 40 is lower than the height of the bottom of the first groove 37, it is supported on the upper surface of the bottom of the first groove 37. When the height of the sleeve 40 is higher than the height of the bottom of the first groove 37, it is supported on the upper surface of the sleeve 40. The edge rolling process of the pressing piece is completed by the pressing of the alloy roller ring 19.The utility model has a reasonable structure. The positions of the first internal thread block 31 and the second internal thread block 32 can be adjusted by the roll gap adjustment motor 33, and the first slide plate 16 and the second slide plate 17 are pushed by the push bearings 36 at the ends of the first internal thread block 31 and the second internal thread block 32, so that the distance between the first spindle 12 and the second spindle 13 is adjusted, thereby adjusting the distance between the two alloy roller rings 19, and then completing the adjustment of the roll gap width. The utility model is simple to operate and is convenient for rapid adjustment of the roll gap width. At the same time, the alloy roller ring 19 is respectively fastened to the first spindle 12 and the second spindle 13 through the expansion sleeve 18, which greatly improves the convenience and efficiency of replacing the alloy roller ring 19. The first spindle 12 and the second spindle 13 are respectively connected to the first slide plate 16 and the second slide plate 17 through the spindle box. Therefore, the first spindle 12 and the second spindle 13 are lifted and lowered with the lifting support plate 8, so that the height of the alloy roller ring 19 can be adjusted, thereby facilitating the control of the distance between the pressing area and the bottom support area, and the flexibility and scope of application are greatly improved.
