[0031] The driving mechanism comprises a bidirectional screw rod 5 and a first slider 10 . The bidirectional screw rod 5 is rotatably connected between the two side supports 3 . The first slider 10 slidably sleeved on the outer wall of the bidirectional screw rod 5 is installed on the top of the rotary peeling machine 9 .

[0034] When the movable end of the double-head hydraulic press 704 is extended, the angle between the axis of the long connecting rod 710 and the inner support rod 703 increases.

[0035] The second hinged seats 15 are arranged at equal intervals along the circumferential outer wall of the second sliding seat 706 .

[0039] A motor 16 for driving the bidirectional screw rod 5 is arranged on the outer wall of one of the side supports 3 .

[0040] The working principle is: When performing the peeling process, after the pipe fitting is sleeved on two symmetrically distributed limiting cone blocks, the first slide is moved along the arc-shaped slide groove to fix the pipe fitting between the first slide and the column, so that the pipe fitting is in a stable state, and the motor is started. The motor drives the bidirectional screw rod to rotate, and the first limiting slide rod and the second limiting slide rod are guided, thereby driving the rotary peeling machine to move synchronously inward, and the rotary peeling machine itself completes the rotation and movement operations, thereby effectively avoiding the possibility of displacement of the pipe fitting and reducing the defective rate. In addition, under this structure, multiple pipe fittings can also be peeled at the same time, which plays a role in improving work efficiency; When it is necessary to fix the pipe fittings, first put the pipe on the limiting cone block 7 for simple support, then start the double-head hydraulic press, and under the action of the hydraulic rods on both sides, drive the second slide seat to move along the slide groove to change the angle between the long connecting rod and the short connecting rod, thereby changing the support height of the support block, pressing the inner wall of the pipe from the inside, and gradually changing the height of the pipe until it is stably supported with the inner support rod as the axis. Without changing the clamping tool, stable support for all specifications of pipe fittings between a diameter greater than the limiting cone block and a maximum stripping diameter less than the rotary stripping machine can be achieved, thereby improving the adaptability of the equipment and reducing the difficulty of equipment adjustment between stripping operations for pipe fittings of different specifications. Under the action of the magnetic suction sheet, the support block can be limited before it contacts the inner wall of the pipe fitting to ensure normal contact between the support block and the inner wall of the pipe.

[0041] When the above-mentioned wire metal pipe peeling guide fixture is used, after the pipe fitting is put on two symmetrically distributed limiting cone blocks, the first slide is moved along the arc slide groove to fix the pipe fitting between the first slide and the column, and then the two movable ends of the double-headed hydraulic valve are synchronously extended and contracted to drive the second slide to move along the slide groove. When the movable end of the double-headed hydraulic valve is extended, the short connecting rod lifts the long connecting rod, thereby increasing the angle between the long connecting rod and the inner support rod, which is beneficial to the close contact between the support block and the inner wall of the pipe fitting, realizes multiple fixations of the pipe fitting, improves the consistency of the clamping of the pipe fitting, improves the stability of the clamping and fixing of the pipe fitting, greatly reduces the movement of the pipe fitting during processing, and can also control the moving distance of the second slide to adjust the distance between the support block and the inner support rod to adapt to the clamping requirements of different pipe fittings and expand the applicability of the device.
