DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figures 1 to 4 As shown, a ring die self-disassembly tool comprises two left-right symmetrical columns 1, an upper crossbeam 2 and a lower crossbeam 3 are welded between the two columns 1, and the upper crossbeam 2 and the lower crossbeam 3 are parallel to each other.

[0022] A suspension bracket 4 is suspended on the upper crossbeam 2, and the suspension bracket 4 includes a rectangular mounting plate 41. A vertical plate 42 perpendicular to the mounting plate is welded to the top of the mounting plate 41, and two left-right symmetrical hanging plates 43 are welded to one side of the vertical plate 42. The mounting plate 41 is parallel to the two hanging plates 43 respectively, and a first clamping groove 44 is formed between the mounting plate 41 and the hanging plate 43 to clamp the wing plate of the upper crossbeam 2. The first clamping groove 44 is used to clamp the wing plate of the upper crossbeam 2, so that the suspension bracket 4 is hung on the upper crossbeam.

[0023] Two vertical reinforcing ribs 21 symmetrically arranged front to back are welded to the middle of the upper cross beam 2 , and the reinforcing ribs 21 increase the strength of the middle of the upper cross beam 2 .

[0024] A second clamping groove 45 clamped on the reinforcing rib 21 is formed between the two hanging plates 43. The second clamping groove 45 cooperates with the reinforcing rib to facilitate the hanging frame to quickly find a hanging position.

[0025] A telescopic cylinder 5 is installed at the bottom end of the suspension bracket 4. Specifically, the telescopic cylinder 5 is installed at the bottom end of the mounting plate 41 with bolts.

[0026] A cylindrical punching block 6 is installed at the end of the piston rod of the telescopic cylinder 5.

[0027] A pad 7 is placed on the lower crossbeam 3. A circular through hole 71 is provided in the center of the pad 7. The diameter of the circular through hole is larger than the outer diameter of the pressure roller shaft and smaller than the outer diameter of the ring die.

[0028] The central axis of the punching block and the central axis of the circular through hole are located on the same vertical line.

[0029] Two upwardly protruding limiting ridges 72 are provided on the top of the pad 7. The two limiting ridges 72 are arranged symmetrically about the circular through hole 71. An arc-shaped limiting groove 73 is provided on one side of the limiting ridge 72 close to the circular through hole 71.

[0030] A U-shaped handle 74 is welded to each end of the cushion block 7 .

[0031] Two front-to-back symmetrical positioning blocks 31 are welded in the middle of the top of the lower crossbeam 3, and two front-to-back symmetrical positioning grooves 75 are opened in the middle of the bottom of the pad 7. The positioning blocks 31 and the positioning grooves 75 are plugged in and out to facilitate the pad to quickly find a placement position.

[0034] The telescopic cylinder is suspended and installed on the upper crossbeam by a suspension bracket, a punching block is installed at the end of the piston rod of the telescopic cylinder, and a pad with a circular through hole is placed on the lower crossbeam. The ring die of the pressure roller to be disassembled is placed on the pad, and the pressure roller shaft of the pressure roller is aligned with the circular through hole. The telescopic cylinder is started to extend the piston rod of the telescopic cylinder to allow the punching block to punch the pressure roller shaft of the pressure roller downward, thereby pushing the pressure roller shaft downward from the ring die to achieve disassembly of the ring die. In addition, the telescopic cylinder is installed by using the suspension bracket, which makes it convenient to remove the telescopic cylinder from the upper crossbeam when not in use, thereby preventing the telescopic cylinder from being damaged due to long-term inversion.
