[0052] A switching assembly 500, which is used to switch the bending assembly 400. The switching assembly 500 includes an installation opening formed on the lower surface of the working platform 200, and a rotating rod 501 rotatably arranged on the inner wall of the installation opening and extending to the outer surface of the working platform 200. One end of the rotating rod 501 is fixedly provided with a rotating disk 502. The number of the bending assemblies 400 is several, and several mounting plates 401 are fixedly arranged on the outer surface of the rotating disk 502 in a circumferential array. The switching assembly 500 further includes a stepping motor 503 fixedly arranged on the lower surface of the working platform 200 for driving the rotating rod 501 to rotate.

[0053] Referring to Figure 2 and Figure 4 In a preferred embodiment, a second driving gear disk 504 is fixedly provided at the output end of the stepping motor 503, and a second driven gear 505 meshing with the second driving gear disk 504 is fixedly provided on the outer surface of the rotating rod 501.

[0054] By setting the second driving gear disk 504 and the second driven gear 505, it is convenient to drive the rotating rod 501 and the rotating disk 502 to rotate at a reduced speed through the rotation of the stepping motor 503.

[0055] In this embodiment, by setting the switching assembly 500 and setting the number of the bending assemblies 400 to several, during the actual use of this pipe bender, it can switch the bending assembly 400 according to the size specifications of different pipe fittings, so that this pipe bender can realize the bending of pipe fittings with different specifications and sizes, and has strong applicability.

[0056] Working principle: During actual use, the pipe bender can insert several pipe fittings into several wheel molds 403 and into several fixed pipes 302. After fixing the pipe fittings by simultaneously turning two fixing bolts 305, the first motor 303 is started to drive the threaded column 304 to rotate. The rotation of the threaded column 304 drives the push plate 301 to move, and the movement of the push plate 301 drives several pipe fittings to move. When the pipe fittings move to the specified position, the hydraulic rod 4011 is started to drive the sliding plate 406 to move, so that the pressing die 407 presses and limits the pipe fittings. Then, the second motor 408 is started to drive the first driving gear 409 to rotate. The rotation of the first driving gear 409 drives the first driven gear 4010 and the rotating sleeve 404 to rotate. The rotation of the rotating sleeve 404 drives the L-shaped plate 405 to rotate, thereby driving the pressing die 407 to rotate, realizing the simultaneous bending of several pipe fittings, effectively improving the working efficiency. Moreover, during actual use, the pipe bender can, according to the size specifications of different pipe fittings, drive the second driving gear 405 to rotate by the rotation of the stepping motor 503. The rotation of the second driving gear 405 drives the second driven gear 505 and the rotating rod 501 to rotate, thereby driving the rotating disc 502 to rotate. The rotation of the rotating disc 502 realizes the switching of the bending assembly 400, and further enables the pipe bender to bend pipe fittings of different specifications and sizes, with strong applicability.
