[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides two technical solutions:

[0024] Figures 1-5The first embodiment is shown: a bending machine with bending angle adjustment function, including a worktable 1, a support frame 11 installed on the top of the worktable 1 near the rear side, a conveying assembly 2 located on the top of the worktable 1 near the left side, a rotating assembly 3 located on the top of the worktable 1 to the right of the conveying assembly 2, an extrusion assembly 4 located outside the rotating assembly 3, and a bending assembly 5 located on the top of the worktable 1 to the right of the rotating assembly 3; the rotating assembly 3 is used to drive the pipe to rotate, and the rotating assembly 3 includes a vertical plate 31 fixedly installed on the top of the worktable 1, and the vertical plate 31 is externally... A hollow shaft 32 is provided through the surface, and the hollow shaft 32 can rotate relative to the vertical plate 31. An external gear ring 33 is fixedly connected to the right end of the hollow shaft 32, and a fixing ring 36 is fixedly connected to the front end of the external gear ring 33. The fixing ring 36 has two semi-conical clamps 37 inside for holding the pipe. Multiple springs 38 are installed on the inner wall of the fixing ring 36 to generate tension on the semi-conical clamps 37. The extrusion assembly 4 includes two cylinders 41 fixedly installed on the top of the workbench 1. A connecting plate 42 is fixedly connected between the telescopic ends of the two cylinders 41. A circular ring 43 is fixedly installed inside the connecting plate 42. A circular ring 43 surrounds the outer sides of two semi-conical clamping plates 37. Multiple balls 44 are movably embedded in a circumferential array on the inner wall of the ring 43. Through a cylinder 41, the connecting plate 42 and the ring 43 can move left and right. When moving to the left, the balls 44 on the inner wall of the ring 43 contact the outer surface of the semi-conical clamping plates 37, causing the two semi-conical clamping plates 37 to be compressed, thereby clamping the pipe fitting. Conversely, when the connecting plate 42 and the ring 43 move to the right, the clamping state on the two semi-conical clamping plates 37 is released. When the semi-conical clamping plates 37 are not clamped, the spring... Under the action of the tension 38, the semi-conical clamp 37 opens to facilitate the conveying of the pipe fitting. When the pipe fitting is in the clamping state, the second motor 34 drives the drive gear 35 to rotate. The drive gear 35 meshes with the external gear ring 33, driving the hollow shaft 32 and the fixed ring 36 to rotate. The fixed ring 36 is connected to the semi-conical clamp 37 through the guide rod 39, which allows the semi-conical clamp 37 to rotate, thereby driving the pipe fitting to rotate. When the semi-conical clamp 37 holds the pipe fitting and rotates, the ball bearing 44 can effectively reduce the friction between the semi-conical clamp 37 and the ring 43, thereby improving the power transmission efficiency.

[0025] The conveying assembly 2 includes a lower roller support 21, a first motor 23, and a hydraulic rod 24. The lower roller support 21 is mounted on the top of the worktable 1, and multiple lower conveying rollers 22 are rotatably arranged inside the lower roller support 21. The first motor 23 is mounted on the top of the worktable 1, and the output shaft of the first motor 23 movably passes through the outer surface of the lower roller support 21 and is fixedly connected to the end of one of the lower conveying rollers 22. The hydraulic rod 24 is mounted on the top of the support frame 11, and the telescopic end of the hydraulic rod 24 slides through the top of the support frame 11 and extends downward. An upper roller support 25 is fixedly installed on the telescopic end of the hydraulic rod 24, and multiple upper conveying rollers 26 are rotatably arranged inside the upper roller support 25. By adjusting the distance between the upper conveying rollers 26 and the lower conveying rollers 22 through the hydraulic rod 24, the pipe can be clamped. In conjunction with the first motor 23 driving the corresponding lower conveying rollers 22 to rotate, the pipe can be conveyed. At the same time, it is convenient to perform multiple continuous bending operations on the pipe, which meets the needs of diversified processing.

[0026] A second motor 34 is mounted on the right surface of the upright plate 31. The output shaft of the second motor 34 extends through the right surface of the upright plate 31 and to the other side. A drive gear 35 is mounted on the output shaft of the second motor 34 and meshes with the external gear ring 33. The second motor 34 drives the drive gear 35 to rotate. The drive gear 35 meshes with the external gear ring 33, which can drive the hollow shaft 32 and the fixed ring 36 to rotate. Multiple guide rods 39 are fixedly connected to the outer surface of the semi-conical clamping plate 37. The outer wall of the guide rod 39 extends through the inner wall of the fixed ring 36 and extends outward. The guide rods 39 ensure the stability of the semi-conical clamping plate 37 in the fixed ring 36 and also serve to connect the semi-conical clamping plate 37 and the fixed ring 36.

[0027] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the bending assembly 5 includes a third motor 51, a turntable 53 and a U-shaped frame 56. The third motor 51 is fixedly installed at the bottom of the workbench 1, and a worm gear 52 is installed at the output end of the third motor 51.

[0028] Turntable 53 is set on top of workbench 1. Two bent columns 58 are installed on the right side of the top of turntable 53. A rotating shaft 54 ​​is fixedly connected to the bottom of turntable 53. The outer surface of rotating shaft 54 ​​moves through the top of workbench 1 and extends downward. A worm wheel 55 that meshes with worm gear 52 is fixedly connected to the bottom of rotating shaft 54.

[0029] The U-shaped frame 56 is fixedly installed on the top of the workbench 1. Two stop posts 57 are symmetrically installed on the top of the U-shaped frame 56. The stop posts 57 are positioned above the turntable 53. The worm gear 52 is driven to rotate by the third motor 51. The worm gear 52 meshes with the worm wheel 55, which drives the turntable 53 to rotate. The bending post 58 at the top of the turntable 53 rotates accordingly and works with the stop posts 57 to limit the pipe fitting, thereby realizing the bending operation of the pipe fitting.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] First, the pipe to be bent is placed on the lower conveyor roller 22. Then, the height of the upper conveyor roller 26 is adjusted by the extension and retraction of the hydraulic rod 24 to clamp the pipe. Then, the lower conveyor roller 22 is driven to rotate by the first motor 23 to realize the conveying of the pipe.

[0032] When the pipe passes through the central channel of the rotating assembly 3 and the extrusion assembly 4 and enters the bending assembly 5, the third motor 51 drives the worm 52 to rotate. The worm 52 meshes with the worm wheel 55, driving the turntable 53 to rotate. The bending column 58 at the top of the turntable 53 rotates accordingly and works with the stop column 57 to limit the pipe, thereby realizing the bending operation of the pipe.

[0033] When the pipe needs to be bent at a three-dimensional angle, the cylinder 41 is retracted, causing the connecting plate 42 and the ring 43 to move to the left. The ball bearings 44 on the inner wall of the ring 43 contact the outer surface of the semi-conical clamping plate 37, causing the two semi-conical clamping plates 37 to be compressed. The pipe is then clamped by the two semi-conical clamping plates 37. Then, the clamping of the pipe by the conveying component 2 is released. After that, the second motor 34 drives the drive gear 35 to rotate. The drive gear 35 meshes with the outer gear ring 33, causing the hollow shaft 32 and the fixed ring 36 to rotate. The fixed ring 36 is connected to the semi-conical clamping plate 37 through the guide rod 39, which allows the semi-conical clamping plate 37 to rotate, thereby causing the pipe to rotate. This rotation function allows the pipe to change its angle in three-dimensional space, breaking through the limitation of traditional bending machines that can only bend in the same plane.
