[0022] As Figures 1-3 shown, a pipe bender for bathroom production with anti - fracture function provided by an embodiment of the present utility model includes a housing 1. A fixed disk 5 is fixed on the top of the housing 1. The outer wall of the top of the housing 1 is connected with a rotating shaft 6 through a bearing. The top end of the rotating shaft 6 is fixed with a cross arm 7. A sliding seat 8 is slidably connected to one side of the cross arm 7. The bottom of the sliding seat 8 is connected with an extrusion wheel 9 through a bearing. A pipe fitting body 4 is arranged between the extrusion wheel 9 and the fixed disk 5. Arc grooves 21 are arranged on the outer walls of both the extrusion wheel 9 and the fixed disk 5. A support base 2 is fixed on the outer wall of the top of the housing 1. An electromagnetic heating component 3 is fixed on one side outer wall of the support base 2. The pipe fitting body 4 is inserted into the inside of the electromagnetic heating component 3.

[0023] Specifically, in this embodiment, it includes a housing 1. A fixed disk 5 is fixed on the top of the housing 1. The outer wall of the top of the housing 1 is connected with a rotating shaft 6 through a bearing. The rotating shaft 6 is located at the center of the fixed disk 5. The top end of the rotating shaft 6 is fixed with a cross arm 7. A sliding seat 8 is slidably connected to one side of the cross arm 7. The bottom of the sliding seat 8 is connected with an extrusion wheel 9 through a bearing. A pipe fitting body 4 is arranged between the extrusion wheel 9 and the fixed disk 5. When the cross arm 7 rotates, the pipe fitting body 4 is bent by the extrusion wheel 9. Arc grooves 21 are arranged on the outer walls of both the extrusion wheel 9 and the fixed disk 5. The arc grooves 21 enable the pipe fitting body 4 to be more evenly stressed during bending, and can prevent the pipe fitting body 4 from being squeezed during bending. A support base 2 is fixed on the outer wall of the top of the housing 1. An electromagnetic heating component 3 is fixed on one side outer wall of the support base 2. The support base 2 is fixed to the housing 1 by bolts, so that it is convenient to replace the electromagnetic heating component 3 when it is damaged. The pipe fitting body 4 is inserted into the inside of the electromagnetic heating component 3. When the electromagnetic heating component 3 is connected to high - frequency alternating current, it can heat the pipe fitting body 4.

[0024] A pipe bender for bathroom production that prevents breakage. The electromagnetic heating component 3 is provided to heat the pipe body 4, and then the pressing wheel 9 rotates around the fixed disk 5, so that the pipe body 4 is not likely to generate cracks or break during bending, thereby improving the production quality of bathroom pipes.

[0025] In another embodiment provided by the present utility model, an electric telescopic rod 15 is hinged to the outer wall of one side of the cross arm 7, and the output end of the electric telescopic rod 15 is hinged to the sliding seat 8. The electric telescopic rod 15 is used to drive the sliding seat 8 to move. A sliding groove 19 is provided on the outer wall of the top of the cross arm 7, and a slider 20 is slidably connected inside the sliding groove 19. The slider 20 is fixed to the sliding seat 8. By sliding the slider 20 inside the sliding groove 19, the movement of the sliding seat 8 is made more stable. A nut 16 is fixed to the outer wall of one side of the sliding seat 8, and a locking screw 17 is threadedly connected inside the nut 16. One end of the locking screw 17 abuts against the cross arm 7, and a force-applying rod 18 is inserted into one end of the locking screw 17. The force-applying rod 18 is convenient for rotating the locking screw 17. By setting the electric telescopic rod 15 to drive the sliding seat 8 to move, the distance between the pressing wheel 9 and the fixed disk 5 can be finely adjusted, and then the sliding seat 8 is fixed by the locking screw 17, so that the pipe bender can bend bathroom pipes of various sizes.

[0026] In another embodiment provided by the present utility model, two guiding wheels 13 are rotatably connected to the outer wall of the top of the housing 1. The pipe body 4 is located between the two guiding wheels 13. The two guiding wheels 13 make the feeding of the pipe body 4 more stable during bending; a side baffle 14 is fixed to the outer wall of the top of the housing 1. The side baffle 14 is located on the side of the pipe body 4 away from the fixed disk 5. The electromagnetic heating component 3 is located between the guiding wheel 13 and the side baffle 14. The contact part of the side baffle 14 and the pipe body 4 is an arc surface, so that the side baffle 14 can play a role in blocking the pipe body 4 during bending; the bottom end of the rotating shaft 6 extends into the interior of the housing 1 and is fixed with a worm gear 10. A worm 11 is connected to the interior of the housing 1 through a bearing. The worm 11 meshes with the worm gear 10. By using the meshing transmission of the worm 11 and the worm gear 10, the torque obtained by the rotating shaft 6 is increased and the rotation speed is reduced. A motor 12 is fixed to the outer wall of one side of the housing 1. The output shaft of the motor 12 is key-connected to the worm 11. By setting the motor 12 to drive the worm 11 to rotate, the worm 11 drives the worm gear 10 and the rotating shaft 6 to rotate, so that the torque obtained when the cross arm 7 moves is increased, the bending performance of the pipe bender is improved, and the moving speed of the cross arm 7 is slowed down to prevent the pipe body 4 from breaking due to the too fast movement of the cross arm 7.

[0027] Working principle: When it is necessary to bend the pipe fitting body 4, first heat the part of the pipe fitting body 4 that needs to be bent through the electromagnetic heating component 3, then move the pipe fitting body 4 so that the bent part is located between the extrusion wheel 9 and the fixed disk 5, and then drive the worm 11 to rotate through the motor 12, so that the worm 11 drives the worm wheel 10 and the rotating shaft 6 to rotate, and further makes the rotating shaft 6 drive the cross arm 7 to move, so that the cross arm 7 drives the extrusion wheel 9 to move around the fixed disk 5, and further makes the extrusion wheel 9 bend the pipe fitting body 4.

[0028] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
