Description

Technical Field

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

[0002] In mechanical manufacturing processes, pipe fittings are commonly used raw materials. To ensure that metal pipe fittings have the required shape or to facilitate smooth connection between metal pipes, workers often use bending equipment to bend various metal pipe fittings. Currently, there are various types and structures of pipe bending equipment on the market. For example, publication number CN221559418U discloses a metal pipe bending device, including a worktable and a rotating wheel mounted on the upper part of the worktable. The worktable contains a drive device for driving the rotating wheel to rotate. A first L-shaped plate is fixedly mounted on the lower end of the side wall of the rotating wheel. A first adjusting bolt is threaded through the side wall of the profile plate, and a clamping plate is slidably provided on the upper end of the first L-shaped plate. One end of the first adjusting bolt is rotatably connected to the clamping plate. A constraint component that cooperates with the rotating wheel is provided on one side of the upper end of the worktable. The beneficial effect of this utility model is that by setting the first L-shaped plate, clamping plate, first adjusting bolt and rotating wheel, the rotation of the rotating wheel drives the first L-shaped plate, clamping plate and first adjusting bolt to deflect and adjust their positions synchronously. This makes it easier for the worker to insert one end of the pipe to be processed between the clamping plate and the rotating wheel, and then clamp and fix the pipe by rotating the first adjusting bolt.

[0003] However, the existing technology has some problems: the existing technology bends the pipe by rotating a wheel, but the size of the rotating wheel is fixed and the position is fixed and cannot be adjusted. Therefore, although the device can bend the pipe, it can only bend the pipe into a fixed arc and cannot bend the pipe to different degrees according to the processing needs, so its applicability is low. Therefore, we propose a pipe bending device. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for pipe bending equipment.

[0005] According to a first aspect of this utility model, a pipe bending device is provided, including a worktable with a circular hole. A brake motor is installed on the worktable, and the output shaft of the brake motor is connected to a rotating shaft via a coupling. At least three discs of different sizes are fixedly sleeved on the outer surface of the rotating shaft. A square frame is fixedly installed on the outer surface of each disc. The brake motor is connected to the worktable via an adjustment assembly, which can control the position of the brake motor and the discs to achieve different degrees of bending effect. A clamping assembly is also provided on the worktable for clamping and limiting the pipe fitting. A controller is fixedly installed on the right side of the top of the worktable.

[0006] Optionally, the adjustment assembly includes a drive motor, which is fixedly mounted on the top of the worktable. The output shaft of the drive motor is connected to a lead screw via a coupling. A lifting plate is threaded onto the outer surface of the lead screw. A brake motor is fixedly mounted on the lifting plate. A vertical plate is fixedly mounted on the lifting plate, and the top of the vertical plate penetrates the worktable.

[0007] Optionally, the clamping assembly includes a fixing plate, which is fixedly mounted on the top of the workbench. A threaded rod is threaded onto the fixing plate, and a frame is rotatably connected to one end of the threaded rod near the wheel. A pressure roller is rotatably connected to the frame.

[0008] Optionally, there are two uprights, which are arranged symmetrically, and a top plate is fixedly connected between the tops of the two uprights.

[0009] Optionally, a slide rail is fixedly installed at the center of the bottom end of the top plate, and two slide rods are slidably connected on the slide rail, with the bottom end of the slide rods passing through the wheel.

[0010] Optionally, a guide rod is fixedly installed on the frame, and the other end of the guide rod passes through the fixing plate.

[0011] Optionally, the slide rail is annular in shape, and its outer surface is coated with a lubricating layer.

[0012] Optionally, the number of pressure rollers is two, and the clamping surfaces of both pressure rollers are set in an arc shape.

[0013] 1. According to one embodiment of this disclosure, by setting a wheel and an adjustment component, when in use, after the operator clamps and limits the pipe fitting, the operator can start the brake motor to make the rotating shaft drive the wheel to rotate, thereby bending the pipe fitting. If different degrees of bending are required, the operator can adjust the wheel of different diameter size to the bending position before bending by adjusting the adjustment component, so that the pipe fitting can be bent to different degrees as needed, which can meet different processing requirements and improve applicability.

[0014] 2. According to one embodiment of this disclosure, by setting a slide rail and a slide rod, when the wheel rotates to bend the pipe, the slide rod can be driven to slide on the slide rail. Through the design of the slide rail and slide rod, the wheel is well supported and guided, making the process of the wheel bending the pipe more stable. Furthermore, by coating the surface of the slide rail with a lubricating layer, the slide rod can slide more smoothly along the outer surface of the slide rail, thereby achieving good support and guidance for the wheel without affecting the rotation of the wheel.

[0015] 3. According to one embodiment of this disclosure, by setting a pressure roller and setting the clamping surface of the pressure roller to be arc-shaped, the clamping effect on the pipe can be improved, and pipes of different diameters with smaller diameters can be clamped to bend pipes of different sizes.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figures 1-5 As shown, a pipe bending device includes a worktable 1 with a circular hole 2. A brake motor 3 is mounted on the worktable 1, and the output shaft of the brake motor 3 is connected to a rotating shaft 4 via a coupling. At least three wheel discs 5 are fixedly fitted onto the outer surface of the rotating shaft 4. The three wheel discs 5 are of different sizes, and a square frame 6 is fixedly installed on the outer surface of the wheel discs 5. The brake motor 3 is connected to the worktable 1 via an adjustment component, which can control the position of the brake motor 3 and the wheel discs 5 to achieve different degrees of bending effect. A clamping component is also provided on the worktable 1 for clamping and limiting the pipe fittings. A controller 7 is fixedly installed on the right side of the top of the worktable 1.

[0029] By setting up the wheel 5 and the adjustment component, when in use, after the operator clamps and limits the pipe fitting, they can start the brake motor 3 to make the rotating shaft 4 drive the wheel 5 to rotate, thereby bending the pipe fitting. If different degrees of bending are required, the operator can adjust the wheel 5 of different diameter sizes to the bending position before bending by adjusting the adjustment component, so that the pipe fitting can be bent to different degrees as needed, which can meet different processing requirements and improve applicability.

[0030] The aforementioned pipe bending equipment includes an adjustment component comprising a drive motor 8, which is fixedly installed on the top of the workbench 1. The output shaft of the drive motor 8 is connected to a lead screw 9 via a coupling. A lifting plate 10 is threaded onto the outer surface of the lead screw 9. A brake motor 3 is fixedly installed on the lifting plate 10. A vertical plate 11 is fixedly installed on the lifting plate 10, and the top of the vertical plate 11 penetrates the workbench 1.

[0031] By starting the drive motor 8, the staff can rotate the lead screw 9, which in turn causes the lifting plate 10 to drive the brake motor 3 to move up or down. This allows the wheel 5 of different diameters to be adjusted to the bending position, enabling the pipe fittings to be bent to different degrees as needed, thus meeting different processing requirements and improving applicability.

[0032] The aforementioned pipe bending equipment includes a clamping assembly comprising a fixing plate 15, which is fixedly installed on the top of the workbench 1. A threaded rod 16 is threaded onto the fixing plate 15, and a frame 17 is rotatably connected to one end of the threaded rod 16 near the wheel 5. A pressure roller 18 is rotatably connected to the frame 17.

[0033] By rotating the threaded rod 16, the staff can cause the frame 17 to drive the pressure roller 18 to move closer to the disc 5, thereby cooperating with the square frame 6 to clamp and limit the pipe fitting, ensuring the stability of the pipe fitting during bending.

[0034] The above-mentioned pipe bending equipment has two vertical plates 11, which are arranged symmetrically, and a top plate 12 is fixedly connected between the tops of the two vertical plates 11.

[0035] The design of two upright plates 11 makes the lifting plate 10 more stable when moving up and down.

[0036] In the aforementioned pipe bending equipment, a slide rail 13 is fixedly installed at the middle of the bottom end of the top plate 12. Two slide rods 14 are slidably connected on the slide rail 13, and the bottom end of the slide rod 14 passes through the wheel disc 5.

[0037] The design of slide rail 13 and slide rod 14 can provide good support and guidance for the wheel 5 when bending the pipe, making the bending process more stable.

[0038] The aforementioned pipe bending equipment has a guide rod 19 fixedly installed on the frame 17, with the other end of the guide rod 19 penetrating through the fixing plate 15.

[0039] The aforementioned pipe bending equipment has a slide rail 13 that is ring-shaped and has a lubricating layer on its outer surface.

[0040] By applying a lubricating layer to the surface of the slide rail 13, the slide rod 14 can slide more smoothly along the outer surface of the slide rail 13.

[0041] The aforementioned pipe bending equipment has two pressure rollers 18, and the clamping surfaces of both pressure rollers 18 are set in an arc shape.

[0042] By setting the clamping surface of the pressure roller 18 to an arc shape, the clamping effect on the pipe can be improved, and pipes of different diameters with smaller diameters can be clamped to bend pipes of different sizes.

[0043] Working principle and usage process of this utility model:

[0044] First, the operator can select a wheel 5 of appropriate size according to the processing needs. The controller 7 controls the drive motor 8 to rotate, which in turn rotates the lead screw 9. This allows the lifting plate 10 to drive the brake motor 3 to move up or down, thereby adjusting the wheel 5 of different diameters to the bending position. The height of the wheel 5 of appropriate size is aligned with the pressure roller 18. Then, one end of the pipe is inserted into the frame 6. The operator rotates the threaded rod 16, which causes the frame 17 to drive the pressure roller 18 to move closer to the wheel 5 to clamp and limit the pipe. The operator can then control the brake motor 3 through the controller 7, which causes the rotating shaft 4 to drive the wheel 5 to rotate, thus realizing the bending of the pipe.

[0045] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
