[0025] like Figure 2 As shown, a rotating column 502 is movably installed inside the first movable frame 501, and an auxiliary plate 503 is fixedly installed on one side of the rotating column 502. The rotating column 502 can rotate inside the first movable frame 501. When the rotating column 502 rotates, the angle of the auxiliary plate 503 can be adjusted. A support block 507 is provided on one side of the auxiliary plate 503.

[0026] In addition, a plurality of supporting grooves 508 are provided on the other side of the auxiliary plate 503, and a plurality of positioning holes 504 are provided at both ends of the rotating column 502. Connecting frames 505 are fixedly installed on both sides of the outer surface of the first movable frame 501, and one side of the two connecting frames 505 is movably connected with fixing bolts 506. When the fixing bolts 506 are inserted into the positioning holes 504, the rotating column 502 can be prevented from continuing to rotate inside the first movable frame 501.

[0027] Following the above practical example, Figure 3As shown, a second movable frame 201 is fixedly installed on one side of the top surface of the placement plate 2, and a support plate 202 is movably installed inside the second movable frame 201. The support plate 202 can rotate inside the second movable frame 201, and the support plate 202 can be extended and retracted, and the extended support plate 202 is fixed with bolts, and the support plate 202 can be inserted into the support groove 508 to support the inclined auxiliary plate 503.

[0028] like Figure 4 As shown, the placement plate 2 includes a connecting bolt 209 , a slide groove 204 is provided on one side of the top surface of the placement plate 2 , a slide rod 205 is fixedly installed inside the slide groove 204 , a slider 206 is movably connected to the outer surface of the slider 205 , and the slider 206 can move along the slider 205 .

[0029] A movable plate 207 is fixedly installed on the top surface of the slider 206. When the slider 206 moves, the movable plate 207 can be driven to move.

[0032] The working principle of the utility model is as follows: the staff first places the placement plate 2 on the press machine 1, and then, according to the angle of the elbow, rotates the rotating column 502 to adjust the angle of the auxiliary plate 503. After the adjustment is completed, the two fixing bolts 506 are rotated in sequence to insert them into the positioning holes 504, and then the support plate 202 is pulled to make it extend and retract, so that the support plate 202 can be inserted into the support groove 508, and the bolts are used to fix the extended support plate 202, so that the support plate 202 can support the inclined auxiliary plate 503, and the end of the elbow that does not need to be corrected is placed in the placement groove 401 and abutted against the baffle 3, and the end that needs to be corrected is placed on the support The two threaded rods 402 are rotated in sequence to make the two fixing rings 403 clamp and fix one side of the elbow. Then, the position of the correction head pulled by the press 1 is adjusted to be located above the port of the elbow that needs to be corrected, and the press 1 is started. The press 1 pulls the correction head and presses it into the port on one side of the support block 507 to achieve the purpose of correcting the port. The movable plate 207 is moved by the slider 206 to adjust the interval between the limit plate 5 and the placement block 4.
