Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a pipe bending machine which is convenient for feeding. Background Art

[0002] A pipe bending machine is a machine used to bend metal pipes. It bends the pipe at the desired angle and curvature by applying force and applying appropriate processes. A pipe bending machine usually consists of a frame, a curve die, a hydraulic system, and a control system.

[0003] When loading existing pipe bending machines, workers mostly manually push steel pipes into the bending machine for bending. Manual pushing will cause the position of the pipe and the bending rod to be unable to accurately maintain a vertical state. If the axis of the two ends of the pipe is offset, the bending angle of the pipe will not be accurate enough. In addition, manual feeding cannot ensure that the bending position of the same batch of pipes is the same each time. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a pipe bending machine that is easy to feed, including a body 1, a feeding part 2 is arranged inside the body 1, and the feeding part 2 includes: a feeding box 21, a slider 22, a feeding cylinder 23, a guide groove 24, a rotating plate 25, an arc groove 26, a straight groove 27, a linkage rod 28, a connecting rod 29, a feeding clamp 210, a lever 211, a motor 212, a reduction gear 213, a rotating shaft 214, a large gear 215, and a bending rod 216.

[0025] The feed box 21 is slidably connected to the inner side of the machine body 1, a slider 22 is fixedly connected to the side of the feed box 21, a feed cylinder 23 is fixedly connected to the surface of the machine body 1, an output shaft of the feed cylinder 23 is fixedly connected to the surface of the slider 22, a guide groove 24 is provided on the inner side of the machine body 1, a rotating plate 25 is rotatably connected to the inner side of the feed box 21, and the lever 211 will slide along the arc of the guide groove 24, so that the lever 211 will be moved by the guide groove 24 during the movement of the feed box 21 The arc-shaped friction is then used to move the rotating plate 25 to rotate the rotating plate 25. The surface of the rotating plate 25 is provided with an arc-shaped groove 26. When the rotating plate 25 rotates, it will contact the linkage rod 28 through the arc-shaped groove 26, forcing the linkage rod 28 to slide along the arc-shaped groove 26. The linear groove 27 is provided on the inner side of the feed box 21. The inner side of the linear groove 27 is slidably connected with a connecting rod 29, and the connecting rod 29 is slidably connected with the linear groove 27. The inner side of the connecting rod 29 is fixedly connected with a feed clamp 210. The end of the connecting rod 29 away from the feed clamp 210 is fixedly connected with the linkage rod 28, but the connecting rod 29 penetrates the linear groove 27 and is slidably connected, so that when the linkage rod 28 slides along the arc-shaped groove 26, the connecting rod 29 slides along the linear groove 27, and further, the connecting rod 29 drives the feed clamp 210 to fix the pipe. The linkage rod 28 penetrates the arc-shaped groove 26 and is slidably connected. A lever 211 is fixedly connected to the bottom surface of the rotating plate 25, and the lever 211 passes through the guide groove 24 and is slidably connected. When the feed cylinder 23 is started, the output shaft of the feed cylinder 23 will drive the feed box 21 to move in the direction of the bending rod 216 through the slider 22. During the movement of the feed box 21, the lever 211 fixedly connected to the bottom surface of the rotating plate 25 inside the feed box 21 will slide along the guide groove 24.

[0026] The inner wall of the machine body 1 is fixedly connected with a motor 212, the output shaft of the motor 212 penetrates the machine body 1 and is rotatably connected, and the output shaft of the motor 212 penetrates and is fixedly connected with a reduction gear 213. The top surface of the machine body 1 is fixedly connected with a rotating shaft 214, and the rotating shaft 214 penetrates and is fixedly connected with a large gear 215, which meshes with the reduction gear 213, and the top surface of the large gear 215 is fixedly connected with a bending rod 216. When the motor 212 is started, the output shaft of the motor 212 will drive the reduction gear 213 to rotate, and the reduction gear 213 will drive the meshed large gear 215 to rotate, so that the bending rod 216 bends the pipe, and the two sets of feed boxes 21 can ensure that they are fixed, and then the axis of the pipe fed is kept vertical to the bending rod 216. There are two groups of feeding parts 2, and the two groups of feeding parts 2 are respectively arranged on the surface of the machine body 1. Due to the fixed opening length of the guide groove 24, each time the pipe is fixed and fed by the feeding clamp 210, the feeding distance of each group of pipes is guaranteed to be equal, so that the bending position of the pipes is the same, ensuring that the accuracy of each batch of pipes bent is the same.

[0027] Based on the above embodiment, when bending the pipe, the pipe is inserted into the feed box 21, and the feed cylinder 23 is started. The output shaft of the feed cylinder 23 will drive the feed box 21 to move in the direction of the bending rod 216 through the slider 22. During the movement of the feed box 21, the lever 211 fixedly connected to the bottom surface of the rotating plate 25 inside the feed box 21 will slide along the guide groove 24. First, the lever 211 will slide along the arc of the guide groove 24, so that during the movement of the feed box 21, the lever 211 will be resisted by the arc of the guide groove 24, and then the rotating plate 25 will be driven to rotate the rotating plate 25. When the rotating plate 25 rotates, it will resist the linkage rod 28 through the arc groove 26, forcing the linkage rod 28 to slide along the arc groove 26, but the connecting rod 29 passes through the straight groove 27 and is slidably connected. When the linkage rod 28 slides along the arc groove 26, the connecting rod 29 slides along the straight groove 27, and further, the connecting rod 29 drives the feed clamp 210 to fix the pipe. If the feed cylinder 23 continues to push, the lever 211 will slide along the straight part of the guide groove 24, so that the pipe fixed by the feed clamp 210 is gradually inserted between the bending rods 216, and the motor 212 is started. The output shaft of the motor 212 will drive the reduction gear 213 to rotate, and the reduction gear 213 will drive the meshing large gear 215 to rotate, so that the bending rod 216 bends the pipe. The two sets of feed boxes 21 can ensure that it is fixed, and the axis of the pipe to be fed is kept vertical to the bending rod 216 to prevent the axis of the pipe from shifting and causing the bending angle to shift.

[0028] At the same time, because the guide groove 24 has a fixed length, each time the pipe is fixed and fed by the feeding clamp 210, the feeding distance of each group of pipes is equal, so that the bending position of the pipes is the same, ensuring that the accuracy of each batch of pipes bent is the same.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
