[0002] A hydraulic arc bending machine is a pipe fitting processing device that can bend pipe fittings into the required radius. Special-shaped pipe fittings are seamless steel pipes of various special shapes made by cold drawing, with diverse cross-sectional shapes, such as rectangular, elliptical, triangular, rhombic, semi-circular, conical, etc., and can be used in fields such as construction and manufacturing.

[0003] Based on the above, the inventor found the following problems: The existing hydraulic arc bending machine has poor processing effects when facing various types of special-shaped pipe fittings. Because the cross-sectional shapes of different types of special-shaped pipe fittings are different, if traditional clamps are used for clamping and processing, the clamps will be severely worn during the bending of pipe fittings, and the surface of the pipe may be damaged or broken, affecting the product quality. If the machine needs to be stopped to replace the clamp corresponding to a certain type of special-shaped pipe fitting, the production efficiency will be reduced, and the manufacturer needs to reserve clamps for various special-shaped pipe fittings, increasing the production cost of the manufacturer.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hydraulic arc bending machine for special-shaped pipe fittings is provided, with the expectation of achieving a more practical value. Content of the Utility Model

A groove is opened on the upper end surface of the movable platform, and a special-shaped pipe fitting clamp is installed in the groove. The special-shaped pipe fitting clamp is composed of an end cover, a plurality of grooved pulleys, and a rotating wheel. A groove is opened on the outer side of the grooved pulley, a rotating clamping plate is installed on the rotating wheel, a support seat is installed inside the rotating wheel, and a clamping plate is installed on the upper end surface of the support seat.

[0009] Further, through holes for bolts to pass through are formed in the inner side of the clamping groove wheel.

[0010] Further, threaded holes are formed in the groove.

[0011] Further, the distance between the two side walls of the clamping groove is the same as the width of the rotating clamping plate.

[0012] Further, a rubber pad is provided on the upper end surface of the clamping plate.

[0013] Further, the hole pitch between a pair of the threaded holes is equal to the sum of the widths of a rotating wheel and a clamping groove wheel.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0025] Embodiment:

[0026] As shown in the Figure 1 to the Figure 4 accompanying drawings:

[0027] The utility model provides a hydraulic arc bending machine for special-shaped pipe fittings, which comprises a machine tool 1, a pipe fitting bending assembly 2 and a movable platform 3. The pipe fitting bending assembly 2 is installed on one side of the machine tool 1. A chute is formed on the upper end surface of the machine tool 1, and the movable platform 3 is installed in the chute. The movable platform 3 can move in the chute. A groove 302 is formed on the upper end surface of the movable platform 3, and a special-shaped pipe fitting clamp 4 is installed in the groove 302. The special-shaped pipe fitting is clamped in the special-shaped pipe fitting clamp 4. The special-shaped pipe fitting clamp 4 is composed of an end cover 407, a plurality of grooved pulleys 401 and a runner 404. A groove 402 is formed on the outer side of the grooved pulley 401. A rotating clamping plate 406 is installed on the runner 404. A support seat 405 is installed on the inner side of the runner 404. A clamping plate 4053 is installed on the upper end surface of the support seat 405. The clamping plate 4053 is used for clamping the special-shaped pipe fitting. After the special-shaped pipe fitting is clamped, the movable platform 3 will carry the pipe fitting into the pipe fitting bending assembly 2 for processing.

[0028] Wherein, a motor 4051 is arranged in the support seat 405. A lead screw 4052 is connected and installed at the output end of the motor 4051. A threaded sleeve 4055 is installed on the lower end surface of the clamping plate 4053. The threaded sleeve 4055 is in threaded engagement with the lead screw 4052. When the motor 4051 is started, its output end drives the lead screw 4052 to rotate, and the clamping plate 4053 is pushed out. Multiple clamping plates 4053 cooperate to clamp the special-shaped pipe fitting in the special-shaped pipe fitting clamp 4.

[0029] Wherein, a through hole 403 for a bolt to pass through is formed on the inner side of the grooved pulley 401. The grooved pulley 401 is installed in the groove 302 through a bolt.

[0030] Wherein, a threaded hole 301 is formed in the groove 302. The bolt passes through the grooved pulley 401 and is assembled and installed with the threaded hole 301, and the grooved pulley 401 sleeved on the bolt is installed in the groove 302.

[0031] Wherein, the distance between the side walls of the groove 402 is the same as the width of the rotating clamping plate 406. The rotating clamping plate 406 can rotate into the groove 402. Through the cooperation of the groove 402 and the rotating clamping plate 406, the runner 404 and the grooved pulley 401 can be connected, and the rotation angle of the runner 404 can be determined, which is convenient for clamping the special-shaped pipe fitting subsequently.

[0032] Wherein, a rubber pad 4054 is arranged on the upper end surface of the clamping plate 4053. The rubber pad 4054 can improve the clamping ability of the clamping plate 4053 and reduce the wear on the surfaces of the fixture and the pipe fitting during the processing of the special-shaped pipe fitting.

[0033] Among them, the hole pitch between a pair of the threaded holes 301 is equal to the sum of the widths of one runner 404 and one grooved pulley 401, which can make the structure of the special-shaped pipe fitting fixture 4 formed by combining a plurality of the runners 404 and grooved pulleys 401 more compact and the clamping effect better.

[0034] Specific usage mode and function of this embodiment:

[0035] Before preparing to process the special-shaped pipe fitting, first rotate each runner 404 to drive the support base 405 to rotate to different angles, place the special-shaped pipe fitting into the special-shaped pipe fitting fixture 4 from the end cover 407, and locally adjust the angle of each runner 404 according to the cross-sectional shape of the special-shaped pipe fitting until the support bases 405 are evenly distributed around the special-shaped pipe fitting and the angle for conveniently clamping the pipe fitting is adjusted. Then rotate the rotary clamping plate 406 to make it rotate into the slot 402 to determine the angles of the runners 404. The device starts to work. Start the motor 4051, and its output end drives the lead screw 4052 to rotate, pushing the clamping plate 4053 out from the support base 405. A plurality of clamping plates 4053 will staggeringly clamp the special-shaped pipe fitting. The movable platform 3 moves along the chute to send the special-shaped pipe fitting into the pipe fitting bending component 2 for processing. Until the special-shaped pipe fitting is bent, reverse the motor 4051. At this time, the processed special-shaped pipe fitting can be taken out. For one type of special-shaped pipe fitting, only the angle of the runner 404 needs to be adjusted once before processing, and then continuous processing can be carried out. Through the above steps, the hydraulic arc bending machine for special-shaped pipe fittings can clamp different types of special-shaped pipe fittings, improve the product quality, reduce the production cost, reduce the time for replacing the mold, and improve the production efficiency.
