Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a support rod pipe bending device. Background Technology

[0002] In the fields of metal processing and pipe manufacturing, pipe bending machines are an important type of equipment widely used in the bending of various pipes.

[0003] An existing pipe bending machine, such as the invention patent document with authorization announcement number "CN219924209U" and patent name "Pipe Bending Machine", discloses a pipe bending machine including a worktable, a hydraulic rod on the surface of the worktable, a fixed plate on the surface of the worktable, a rotating block on the surface of the worktable, a controller on the surface of the worktable, a number of buttons on the surface of the controller, and support devices on both sides of the worktable. The support devices include a placement plate, which is fixedly connected to the worktable. A support plate is slidably connected to the surface of the placement plate. A number of slots are opened on one side of the support plate, and pins are engaged in the slots on the surface of the support plate.

[0004] In the aforementioned patent document, when the pipe needs to be removed after being bent by the rotating block, the pipe will rub against the surface of the rotating block, which may cause scratches on the surface of the pipe, resulting in an unsightly surface that requires further processing. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a support rod pipe bending device to solve the technical problem mentioned in the background art: when the pipe is bent by the rotating block and needs to be removed, the pipe will rub against the surface of the rotating block, which may cause scratches on the surface of the pipe, resulting in an unsightly surface and requiring further processing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A workbench is included, a support frame is fixedly mounted on the workbench, a first rotating rod is rotatably mounted on the support frame, and the axis of the first rotating rod is perpendicular to the workbench surface. A first mounting plate and a second mounting plate are respectively fixed at both ends of the first rotating rod, and both the first and second mounting plates are parallel to the workbench surface. A first bending block and a second bending block for bending pipe fittings are provided on the second mounting plate, and the first bending block is coaxial with the first rotating rod. A motor is fixedly mounted at the bottom of the workbench, the motor output shaft is fixedly connected to the first mounting plate, and the motor output shaft is coaxial with the first rotating rod. A rotating assembly for driving the first bending block to rotate and widening the distance between the first and second bending blocks is provided on the workbench.

[0007] Working principle:

[0008] The pipe to be bent is placed between the first bending block and the second bending block. The first bending block is driven to rotate by the rotating assembly, widening the distance between it and the second bending block to facilitate the insertion of the pipe. The rotating assembly then drives the first bending block to rotate in the opposite direction, so that it and the second bending block together clamp the pipe. The motor is started, and its output shaft drives the first mounting plate and the coaxial first rotating rod to rotate, which in turn drives the second mounting plate and the second bending block fixed on it to rotate synchronously. Through the synergistic action of the first bending block and the second bending block, the pipe is bent. After bending is completed, the motor reverses and resets, and the rotating assembly widens the distance between the first bending block and the second bending block again to facilitate the removal of the bent pipe.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The distance between the first and second bending blocks can be actively adjusted by rotating the assembly, which facilitates the insertion and removal of pipe fittings and provides a stable clamping force during bending. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example:

[0017] like Figure 1As shown, a support rod bending device includes a workbench 1, a support frame 2 is fixed on the workbench 1, a first rotating rod 3 is rotatably mounted on the support frame 2, and the axis of the first rotating rod 3 is perpendicular to the workbench 1 surface. A first mounting plate 4 and a second mounting plate 5 are fixed at both ends of the first rotating rod 3, and both the first mounting plate 4 and the second mounting plate 5 are parallel to the workbench 1 surface.

[0018] like Figure 1 and Figure 2 As shown, the second mounting plate 5 is provided with a first bending block 6 and a second bending block 7 for bending pipe fittings. The first bending block 6 is coaxial with the first rotating rod 3. The first bending block 6 includes a first fixing rod 9, a first fixing ring 10 and a semi-circular fixing block 11. The first fixing rod 9 is rotatably mounted on the second mounting plate 5 and is coaxial with the first rotating rod 3. The first fixing ring 10 is fixed on the first fixing rod 9 and the two are coaxial. The fixing block 11 is fixed on the side wall of the first fixing ring 10 and is located between the first fixing ring 10 and the second bending block 7. The outer wall of the fixing block 11 is provided with a first arc groove 12. The first fixing rod 9 serves as a rotating shaft, and its rotation is driven by a rotating assembly. The first fixing ring 10 rotates synchronously with the first fixing rod 9. The semi-circular fixing block 11 is fixed to the side wall of the first fixing ring 10. The first arc groove 12 on its outer wall is used to accommodate and fit the pipe fitting during the bending process, providing a shaped curved surface.

[0019] like Figure 1 and Figure 2 As shown, the second bending block 7 includes a second fixing rod 13 and a second fixing ring 14. The second fixing rod 13 is fixed on the second mounting plate 5 and is parallel to the first fixing rod 9. The second fixing ring 14 is fixed on the second fixing rod 13. The outer wall of the second fixing ring 14 is provided with a second arc groove 15. The second bending block 7 is fixedly installed on the second mounting plate 5. The second arc groove 15 on the outer wall of the second fixing ring 14 is opposite to the first arc groove 12 on the first bending block 6, and together they form a cavity for clamping and bending the pipe fitting. During the bending process, it acts as a fixed bending mold and cooperates with the first bending block 6 to complete the bending action.

[0020] like Figure 1 and Figure 2As shown, a motor 8 is fixedly mounted on the bottom of the workbench 1. The output shaft of the motor 8 is fixedly connected to the first mounting plate 4, and the output shaft of the motor 8 is coaxial with the first rotating rod 3. The workbench 1 is provided with a rotating assembly for driving the first bending block 6 to rotate and expanding the distance between the first bending block 6 and the second bending block 7. The rotating assembly includes an electric push rod 16, a first guide rail 17, a rack 18, and a gear 19. The electric push rod 16 is fixedly mounted on the workbench 1, the first guide rail 17 is fixedly mounted on the workbench 1, the rack 18 is fixedly mounted on the telescopic end of the electric push rod 16 and slides on the first guide rail 17, and the gear 19 is fixedly mounted on the first fixed rod 9 and meshes with the rack 18.

[0021] like Figure 1 and Figure 2 As shown, when it is necessary to adjust the position of the first bending block 6 to increase or decrease the distance between it and the second bending block 7, the electric push rod 16 is activated. The telescopic end of the electric push rod 16 pushes or pulls the rack 18. The rack 18 slides along the first guide rail 17. Since the rack 18 meshes with the gear 19 fixed on the first fixed rod 9, the linear motion of the rack 18 is converted into the rotational motion of the gear 19, thereby driving the first fixed rod 9 and the entire first bending block 6 to rotate, thus realizing the adjustment of the distance.

[0022] like Figure 1 and Figure 3 As shown, the workbench 1 is provided with two mounting blocks 20. Each mounting block 20 has a groove 21. A slider 22 is slidably mounted on each mounting block 20, and each slider 22 is slidably disposed within one of the two grooves 21. Each slider 22 has a groove 23. Each mounting block 20 has a fixed slider 24, which is slidably disposed within the groove 23. Each slider 22 has a third arc groove 25 on its near-facing end face for constraining the pipe fitting. The workbench 1 is provided with a moving assembly for driving one of the mounting blocks 20 to move. The moving assembly includes a mounting bracket 26 and a second guide rail 27. The assembly includes a first connecting block 28, a second connecting block 29, a third connecting block 30, a fixed base 31, and a handle 32. The mounting frame 26 is fixed on the workbench 1, the second guide rail 27 is fixed on the mounting frame 26, the mounting block 20 is slidably mounted on the second guide rail 27, the first connecting block 28 is fixed on the side of the mounting block 20 away from the slider 22, the second connecting block 29 is hinged to the first connecting block 28, the third connecting block 30 is hinged to the second connecting block 29, the fixed base 31 is fixed on the mounting frame 26, and the end of the third connecting block 30 away from the second connecting block 29 is hinged to the fixed base 31. The handle 32 is fixed on the third connecting block 30.

[0023] like Figure 1 and Figure 3As shown, the sliders 22 on the two mounting blocks 20 can slide along the grooves 21 inside the mounting blocks 20. At the same time, the sliding grooves 23 on the sliders 22 cooperate with the sliding blocks 24 fixed on the mounting blocks 20 to form additional sliding guide constraints. The third arc grooves 25 on the opposite end faces of the two sliders 22 are used to jointly clamp and support the straight section of the pipe fitting. When bending the pipe fitting, the pipe fitting clamped between the first bending block 6 and the second bending block 7 begins to deform, and its straight section will generate an axial force on the third arc grooves 25 of the two sliders 22. At this time, the sliders 22 are no longer rigidly fixed, but can overcome the frictional force and slide along the grooves 21. The sliding mechanism compensates for and absorbs the axial displacement generated by the pipe fitting. The moving component drives one of the mounting blocks 20 to move, thereby moving the slider 22 on it together, so as to adjust the distance between the two sliders 22. The operator moves the third connecting block 30 by turning the handle 32. The third connecting block 30, the second connecting block 29 and the first connecting block 28 form a linkage mechanism through the hinge point. The movement of this mechanism ultimately pushes or pulls the first connecting block 28, so that the mounting block 20 fixed thereto slides smoothly along the second guide rail 27, so as to adjust the distance between the two mounting blocks 20 and the sliders 22 on them.

[0024] Working principle:

[0025] During operation, firstly, the handle 32 is turned to drive the linkage mechanism consisting of the first connecting block 28, the second connecting block 29, and the third connecting block 30, thereby moving one of the mounting blocks 20 along the second guide rail 27 to adjust the distance between the two mounting blocks 20. Then, the straight section of the pipe is placed between the three arc grooves 25 opposite to the two sliders 22 to obtain support. At the same time, the electric push rod 16 in the rotating assembly is activated, causing its telescopic end to drive the rack 18 to move along the first guide rail 17. The gear 19 meshing there rotates accordingly, driving the first fixed rod 9 and the entire first bending block 6 to rotate, thereby widening the distance between the first arc groove 12 on the first bending block 6 and the second arc groove 15 on the second bending block 7. Then, the end of the pipe to be bent is placed into this widened cavity. After that, the electric push rod 16 moves in the opposite direction, driving the first bending block 6 to rotate back, so that it and the fixed second bending block 7 clamp the pipe together.

[0026] Then, the motor 8 at the bottom of the workbench 1 is started. Its output shaft directly drives the first mounting plate 4, the first rotating rod 3, and the second mounting plate 5 to rotate as a whole, thereby driving the second bending block 7 to rotate around the axis of the first rotating rod 3 to bend the pipe. During this process, the axial displacement of the pipe due to deformation will push the two sliders 22, so that they overcome the friction and slide along the sliding groove 21 on the mounting block 20. The guide is maintained by the cooperation of the sliding block 24 and the sliding groove 23, thereby adaptively compensating for the displacement and avoiding scratches on the surface of the pipe. After bending is completed, the motor 8 reverses to reset the bending mechanism, and the electric push rod 16 moves again to widen the gap between the bending blocks, so that the processed pipe can be taken out.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
