[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, an S-shaped pipe bending machine includes a workbench 101, a support base 102 is connected to the workbench 101 by bolts, a pipe feeding assembly 103 and an auxiliary assembly 104 are installed on the support base 102, a driving mechanism is installed on the workbench 101, a pressing mechanism is arranged on the driving mechanism, a clamping mechanism is installed on the pressing mechanism, a bending mechanism is installed on the clamping mechanism, the clamping mechanism includes a plurality of clamping molds 401, a U-shaped groove 404 and a straight groove 405 for clamping the pipe are arranged on the clamping mold 401, and the bending mechanism is arranged on the upper and lower sides of the clamping mold 401. The U-shaped groove 404 and the straight groove 405 of the clamping mold 401 respectively clamp the pipe in a bent state and a straight state to prevent the upward and downward deviation during bending, thereby improving the processing accuracy and bending effect.

[0026] In this embodiment, the driving mechanism includes a rotating table 203, a round shaft 402 and a square shaft 403 are welded on one side of the clamping mold 401, a groove of the same shape as the square shaft 403 is opened on the top of the round shaft 402, and the lowest clamping mold 401 is connected to the top of the rotating table 203 by bolts. The round shaft 402 on the lowest clamping mold 401 is located at the center of the rotating table 203. When bending, the rotating table 203 drives the lowest round shaft 402 to rotate, and the square shaft 403 on the upper clamping mold 401 is inserted into the round shaft 402. The pipe is clamped on the inner side of the upper and lower adjacent clamping molds 401, and the clamping mold 401 rotates around the round shaft 402, thereby bending the pipe.

[0027] In this embodiment, the bending mechanism includes a bending ring 501, which is located on the inner side of the U-shaped groove 404 of the clamping mold 401. A plug-in block 502 is arranged above the bending ring 501, and the plug-in block 502 is welded to the bottom of the clamping mold 401. The bending mechanism also includes a limit block 503, which is located on the outer side of the U-shaped groove 404. When the two clamping molds 401 are connected, the plug-in block 502 is inserted into the bending ring 501. When bending, the bending ring 501 applies force to the pipe, and the limit block 503 restricts the pipe, thereby further improving the bending effect.

[0028] In this embodiment, the driving mechanism includes a lifting seat 201, which is slidably connected to the front side of the workbench 101, and a power base 202 for driving the rotating table 203 to rotate is connected to the top of the lifting seat 201 through bolts.

[0029] In this embodiment, the side of the rotating table 203 is connected to the connecting frame 204 by bolts, the top of the connecting frame 204 is connected to the hydraulic cylinder 301 by bolts, the output end of the hydraulic cylinder 301 is connected to the lifting plate 302 by bolts, the top of one side of the lifting plate 302 is connected to the guide column 303 by bolts, and the uppermost clamping mold 401 is connected to the bottom of the guide column 303 by bolts.

[0030] In this embodiment, the front and rear sides of the clamping mold 401 are detachably connected with connecting pieces 406 , and the side surfaces of the clamping mold 401 are provided with a plurality of holes for installing the connecting pieces 406 .

[0031] Working principle: Before using the device, the matching clamping die 401 is selected according to the diameter of the pipe to be bent. When the bending starts, the pipe feeding component 103 first feeds the straight pipe into the straight groove 405 position of the clamping die 401, and then the hydraulic cylinder 301 is pressed down, and the hydraulic cylinder 301 pushes the lifting plate 302, and the lifting plate 302 pushes the upper clamping die 401 down, so that the separated square shaft 403 approaches the lower round shaft 402 and is inserted. At this time, the pipe is restricted inside the clamping die 401, and the rotating table 203 and the auxiliary component 104 are started, and the rotating table 203 drives the clamping die 401 to move. 01 rotates around the circular axis 402 to perform the first bending. After the first bending is completed, the lifting seat 201 descends and the hydraulic cylinder 301 retracts. The pipe feeding assembly 103 pushes the pipe forward and rotates 180 degrees, then retracts to the processing position, and then the lifting seat 201 is lifted. At this time, the U-shaped groove 404 of the clamping mold 401 matches the shape of the pipe after the first bending. The hydraulic cylinder 301 presses down to make the U-shaped groove 404 between the two clamping molds 401 re-clamp the pipe. Repeated bending using the above method can avoid the up and down deviation of the pipe when bending, so as to achieve a better bending effect.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
