Technical Field
[0001] This utility model relates to the field of metal machining, and in particular to a pipe bending machine for pipe processing. Background Technology
[0002] Metal pipes are manufactured using basic non-cutting processing methods such as stamping and bending. A pipe bending machine is a mechanical device specifically designed for bending metal pipes. It can bend straight pipes into the required angles and shapes according to different needs. Pipe bending machines are widely used in construction, automotive, machinery, aerospace and other industrial fields.
[0003] A search revealed Chinese Patent Publication No. CN21546727U, which discloses a pipe bending machine for pipe processing, relating to the technical field of pipe processing equipment. The machine includes a worktable with support plates fixedly connected to both sides of its upper surface. A horizontal plate is fixedly connected to the upper surface of each support plate, and a pushing cylinder is fixedly connected to the upper surface of the horizontal plate. The output end of the pushing cylinder passes through the horizontal plate and is fixedly connected to a connecting plate located below the horizontal plate. Clamping mechanisms are fixedly connected to the lower surface of the connecting plate and the upper surface of the worktable directly below it. Under the action of the clamping cylinder, a clamping slider slides along a clamping track, changing the distance between the clamping block and the clamping slider.

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.
[0032] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a pipe bending machine, including a base 1 for mounting various components. A bending mechanism is provided on the right side of the top surface of the base 1 for bending metal pipes. The bending mechanism includes a mounting frame 6 for mounting the metal pipe bending structure. A bending wheel 7 is provided on the upper part of the mounting frame 6 for bending the metal pipe; this wheel can be replaced according to bending requirements. An auxiliary bending head 8 is provided on the rear side of the bending wheel 7, which is matched with the bending wheel 7. The auxiliary bending head 8 works in conjunction with the bending wheel 7 to bend the metal pipe. The wheel 7 is driven by a drive motor. A clamping mechanism is provided in the middle of the base 1, which is used to fix the position of the metal pipe during bending processing to facilitate the bending of the metal pipe. The clamping mechanism includes a vertical plate 3, a rotating component 4, and a fixing component 5. The vertical plate 3 is fixedly connected to the base 1. A circular opening 31 is provided in the middle of the vertical plate 3, which is used to facilitate the fixing and movement of the metal pipe. An annular groove 32 is provided on the right side of the vertical plate 3, which is used to facilitate the connection of the fixing component 5. The connecting ring 521 is rotatably connected to the annular groove 32. A conveying component 2 is provided on the left side of the top surface of the base 1, which is used to adjust the bending position of the pipe.
[0033] Furthermore, the conveying assembly 2 includes a fixed frame 22, which is used to connect various components. A No. 3 motor 25 is fixedly connected to the front side of the fixed frame 22, which is used to drive the fixed shaft 23. The output end of the No. 3 motor 25 is fixedly connected to the fixed shaft 23, which is used to connect the conveying roller 24. The fixed shaft 23 passes through the fixed frame 22 and is rotatably connected to it. The outside of the fixed shaft 23 passes through and is fixedly connected to the conveying roller 24. The middle of the conveying roller 24 is provided with an annular groove with a central guide to cooperate with the central guide of the metal pipe. The outside of the roller is provided with a rubber layer to provide higher friction to facilitate the movement of the metal pipe. The conveying assembly 2 also includes an electric push rod 21, which is used to adjust the height of the conveying roller 24 to cooperate with the centering of the metal pipe. The electric push rod 21 is fixedly connected to the bottom of the fixed frame 22 and to the base 1.
[0034] like Figure 3 - Figure 5 The fixing component 5 includes a mounting ring 51, which is used to connect various components. Retaining rings 52 are fixedly connected to both the left and right sides of the mounting ring 51, which are used to protect the central component. A connecting ring 521 is fixedly connected to the left side of the left retaining ring 52, which is used to connect with the upright plate 3. The connecting ring 521 is rotatably connected to the upright plate 3. An auxiliary ring 54 is fixedly connected to the middle of both retaining rings 52, which is used to connect with the rack 551. Multiple clamping elements 55 are provided between the mounting ring 51 and the auxiliary ring 54. These clamping elements 55 cooperate to clamp and fix the metal pipe. A motor 53 is fixedly connected to the upper right side of the right retaining ring 52, which is used to drive the entire component. An internal gear ring 56 is rotatably connected to the left inner side of the mounting ring 51, which is used to drive the multiple clamping elements 55.
[0035] Furthermore, the clamping member 55 includes a rack 551 for moving the fixing plate 555. A first gear 553 meshes with one side of the rack 551, driving the rack 551. A slide 552 is fixedly connected to the other side of the rack 551, facilitating the connection between the rack 551 and the mounting ring 51 and the auxiliary ring 54. The rack 551 and slide 552 pass through and slidably connect with the mounting ring 51 and the auxiliary ring 54. The first gear 553 meshes with an internal gear ring 56, which can simultaneously drive multiple first gears 553 to rotate. A rotating shaft 554 passes through and is fixedly connected to the middle of each first gear 553, facilitating the installation of the first gear 553. The rotating shaft 554 passes through two... A retaining ring 52 is rotatably connected to it, and the uppermost rotating shaft 554 is fixedly connected to the output end of the first motor 53. It is used to cooperate with the drive of the first motor 53. The clamping member 55 also includes a fixing plate 555, which is used to fix the pipe. The fixing plate 555 is fixedly connected to the rack 551. On the left and right sides of the fixing plate 555 away from the rack 551, auxiliary rollers 556 are rotatably connected. The auxiliary rollers 556 are rubber rollers with a certain degree of softness and can produce a certain degree of deformation. When the clamping member 55 completely clamps the metal pipe, it can completely adhere to the metal pipe, thereby fixing its position. When the clamping member 55 slightly loosens the metal pipe, it can cooperate with the conveying component 2 to assist the metal pipe in moving its position.
[0036] Specifically, the rotating component 4 includes a second motor 41, which provides power to the component. The second motor 41 is fixedly connected to the upright plate 3. The output end of the second motor 41 is fixedly connected to a connecting shaft 42, which is used to connect to the second gear 43. The connecting shaft 42 passes through the upright plate 3 and is rotatably connected to it. The second gear 43 is fixedly connected to the right side of the connecting shaft 42, which drives the external gear ring 44 to rotate. The lower part of the second gear 43 meshes with the external gear ring 44. The external gear ring 44 is fixedly connected to the mounting ring 51. When the external gear ring 44 rotates, it can drive the overall fixing component 5 to rotate, thereby adjusting the bending direction of the metal tube. The external gear ring 44 is located on the left side of the mounting ring 51 and will not interfere with the rack 551.
[0037] Working principle: In use, first, the metal tube is passed through the round opening 31 in the middle of the vertical plate 3 and the middle of the fixing component 5, so that the part of the metal tube to be bent passes between the bending wheel 7 and the auxiliary bending head 8. Then, the first motor 53 is turned on, and the first motor 53 will drive the rotating shaft 554 connected to it to rotate. The rotating shaft 554 will drive the first gear 553 connected to it to rotate. The first gear 553 will drive the internal gear ring 56 meshing with it to rotate. When the internal gear ring 56 rotates, the other first gears 553 meshing with it will be driven to rotate. When the first gear 553 rotates, the rack 551 meshing with it will be driven, thereby driving the fixing plate 555 fixed to the rack 551 to move towards the metal tube until the auxiliary roller 556 completely presses the metal tube against it. After the multiple clamping parts 55 completely fix the metal tube, the drive motor can be turned on to make the bending wheel 7 and the auxiliary bending head 8 bend the metal tube.
[0038] When it is necessary to adjust the bending direction of the metal tube, turn on the second motor 41. The second motor 41 will drive the connecting shaft 42 connected to it to rotate. The second gear 43 fixed to the connecting shaft 42 will rotate accordingly, thereby driving the external gear ring 44 meshing with it to rotate. The external gear ring 44 will then drive the fixing component 5 connected to it through the mounting ring 51 to rotate as a whole, so as to adjust the bending direction of the metal tube.
[0039] When the bending position of the metal tube needs to be adjusted, the first motor 53 drives the connected rotating shaft 554 to reverse, thereby causing the first gear 553 to rotate in the opposite direction. This causes the rack 551 to drive the fixed plate 555 and the auxiliary roller 556 to slightly loosen the metal tube. Then the third motor 25 can be turned on. The third motor 25 will drive the connected fixed shaft 23, which in turn drives the connected conveyor roller 24 to rotate, thereby moving the position of the metal tube on the conveyor roller 24. The auxiliary roller 556 will then rotate to assist the movement of the metal tube.
