[0029] Embodiment 1:

[0030] like Figures 1 to 4 As shown, an elbow forming machine includes a workbench 1 and a forming component 2; the forming component 2 includes a driving device 21, a forming wheel 22, a wheel 23, a first arc groove 24 and a second arc groove 25; the forming component 2 is arranged on the workbench 1; the output end of the driving device 21 is arranged and extends out of the workbench 1; the wheel surface of the forming wheel 22 is provided with a first arc groove 24; the forming wheel 22 and the clamp 23 are both arranged on the output end of the driving device 21, and rotate with the driving device 21, and the driving device 21 can be a motor; one end of the clamp 23 is provided with a second arc groove 25 facing one end of the first arc groove 24, and the second arc groove 25 corresponds to the first arc groove 24, and together form a clamping groove, respectively clamping the two arc surfaces of the pipe.

[0031] like Figures 1 to 6 As shown, preferably, the driving device 21 includes a mounting seat 211, a first linear motion mechanism 212, a shaft 213, a gear 214 and a rack 215; the mounting seat 211 is arranged on the workbench 1, and is used to support the mounting shaft 213; the shaft 213 is rotatably arranged on the mounting seat 211, and the shaft 213 is vertically distributed; the top end of the shaft 213 is connected to the forming wheel 22 and the fixture 23, that is, the shaft 213 extends out of the workbench 1 surface; the bottom end of the shaft 213 is provided with a gear 214; the first linear motion mechanism 212 is horizontally arranged at On the working platform 1, the first linear motion mechanism 212 faces the gear 214, and its active end is connected to one end of the rack 215.

The rack 215 is meshed and transmitted with the gear 214, thereby driving the gear 214 to rotate, and the gear 214 is driven to rotate by the rack 215, effectively providing a strong drive to drive the fixture 23 and the forming wheel 22 to rotate. In addition, it should be noted that the specific model of the first linear motion mechanism is not an improvement point of this application, and will not be repeated here.

[0032] How it works

[0033] When in use, the pipe is inserted between the first arc groove 24 and the second arc groove 25, and the first arc groove 24 and the second arc groove 25 clamp one end of the pipe together. Then the first linear motion mechanism 212 is started, and the movable end of the first linear motion mechanism 212 extends, driving the rack 215 to move forward, and the rack 215 moves forward and meshes with the gear 214, driving the gear 214 to rotate, and the shaft 213 rotates with the gear 214, driving the forming wheel 22 and the clamp 23 to rotate a certain angle together. The pipe is clamped and pulled by the forming wheel 22 and the clamp 23, and is bent along the first arc groove 24 on the forming wheel 22 to form an elbow, completing the processing and manufacturing of the elbow. Only one end of the pipe is processed, which reduces the processing range of the pipe and prevents the pipe from being clamped too much and getting stuck.

[0034] like Figures 1 to 4 As shown, preferably, the middle portion of the workbench 1 is a hollow structure; the first linear motion mechanism 212 is located in the hollow structure of the workbench 1 to reduce the volume of the overall device; and the mounting seat 211 is located on the side of the workbench 1 .

[0035] like Figure 3 As shown, preferably, the molding component 2 also includes a first support seat 26 and a limiting wheel 27; the first support seat 26 is arranged on the same side of the workbench 1 where the mounting seat 211 is arranged, and is close to the rack 215; the limiting wheel 27 is rotatably arranged on the first support seat 26, and its rolling surface is in contact with a side of the rack 215 away from the gear 214, and the rack 215 is located between the gear 214 and the limiting wheel 27. The rolling surface of the limiting wheel 27 is always tangential to the direction in which the rack 215 moves forward, and can be used as a limiting wheel 27 to roll on the rack 215 to limit the movement of the rack 215 and prevent the rack 215 from deviating and disengaging from the gear 214, causing the shaft 213 to be unable to rotate.

[0036] like Figure 5 and Figure 6As shown, preferably, the forming wheel 22 includes a rotating wheel 221 and a forming block 222; the rotating wheel 221 is provided with a notch corresponding to the forming block 222, wherein the forming block 222 is a rectangular structure; the forming block 222 is provided on the rotating wheel 221 through the notch, and one side of the forming block 222 is connected to the notch; the rotating wheel 221 is provided with a first notch; the forming block 222 is provided with a second notch; the first notch and the second notch are connected to form a first arc-shaped groove 24 that is approximately circular; when the pipe is formed, one end of the pipe is inserted into the second notch and the first notch. In the second arc groove 25, the second notch of the forming block 222 and the second arc groove 25 clamp one end of the pipe. When the clamp 23 and the forming block 222 rotate together, the second notch and the second arc groove 25 clamp one end of the pipe and rotate, while the other part of the pipe fits the first notch and bends along it. At the same time, the forming block 222 keeps one end of the pipe in a straight line. Only along the first notch, the bending is realized, and the two ends are straight and the middle is bent. After the elbow is prepared and taken out, the first linear motion 212 retracts, driving the gear 214 to reverse, so that the second notch and the clamp 23 are reset.

[0037] Embodiment 2:

[0038] like Figures 1 to 6 As shown, compared with the first embodiment, the difference lies in: a structural form of the clamp 23 is given; the clamp 23 includes a second support seat 231 and a clamp rod 232; the second support seat 231 is arranged on the output end of the driving device 21 and rotates with the output end of the driving device 21; the clamp rod 232 is arranged on the second support seat 231 and rotates with the second support seat 231; a second arc groove 25 is provided at one end of the clamp rod 232 close to the forming wheel 22; the clamp 23 also includes a second linear motion mechanism 233; the second linear motion mechanism 233 is arranged on the second support seat 231, and the second linear motion mechanism 233 can be a cylinder, a hydraulic cylinder or an electric push rod, which mainly drives the clamp rod 232 to move back and forth in its direction; the second linear motion mechanism The movable end of 233 is connected to the end of the clamping rod 232 away from the forming wheel 22; the movement direction of the movable end of the second linear motion mechanism 233 is consistent with the length direction of the clamping rod 232; before use, the movable end of the second linear motion mechanism 233 retracts, and the clamping rod 232 is away from the first arc groove 24. When in use, one end of the pipe is inserted into the first arc groove 24, and the movable end of the second linear motion mechanism 233 extends, driving the clamping rod 232 to move forward, so that the first arc groove 24 and the second arc groove 25 cooperate with each other to clamp one end of the pipe. When the forming is completed, the movable end of the second linear motion mechanism 233 retracts, and the clamping rod 232 is separated from the pipe. The pipe loses the clamping of the second arc groove and can be taken out, which is convenient and quick, and it cannot be stuck. In addition, it should be noted that the specific model of the second linear motion mechanism is not an improvement point of this application, so it will not be repeated here.

[0039] Embodiment three:

[0040] like Figures 1 to 6 As shown, compared with the first embodiment, the difference is that: the workbench 1 also includes a limit seat 11; the limit seat 11 is arranged on the table top of the workbench 1; the limit seat 11 is close to the forming wheel 22 and the clamp 23, and the limit seat 11 and the clamp 23 are located on the same side; a limit groove 12 for limiting the pipe is opened on the limit seat 11, and the limit groove 12 is a straight structure, which is on the same horizontal plane as the first arc groove 24 and the second arc groove 25, wherein the limit groove 12 is parallel to the direction of the second arc groove 25 when not in use; during use, the limit groove 12 supports the other end of the pipe to prevent it from rotating, so that it always maintains a straight state.

[0041] like Figures 1 to 3 As shown, the workbench 1 also includes a slide rail 13 and a third linear motion mechanism 14; the limit seat 11 is slidably arranged on the workbench 1 through the slide rail 13; the slide rail 13 and the third linear motion mechanism 14 are both arranged on the table top of the workbench 1, and the directions of the slide rail 13 and the third linear motion mechanism 14 are perpendicular to the direction of the pipe clamped by the limit groove 12; the limit seat 11 is slidably connected to the slide rail 13; the movable end of the third linear motion mechanism 14 is connected to the limit seat 11, driving the limit seat 11 to slide; when the clamp 23 and the forming wheel 22 begin to clamp one end of the pipe, the movable end of the third linear motion mechanism 14 drives the limit seat 11 to move toward the pipe, so that the limit groove 12 fits with the pipe and supports the pipe. When the forming is completed, the third linear motion mechanism 14 contracts, the limit seat 11 is reset, and the limit groove 12 is separated from the pipe, which is convenient for removing the completed elbow.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
