Description

Technical Field

[0001] This utility model relates to the field of industrial pipe processing technology, specifically a multi-axis intelligent pipe bending device. Background Technology

[0002] As core components for industrial fluid transmission, steel pipes and other tubular materials have their processing precision directly affecting the reliability of systems in fields such as energy, chemical industry, and aerospace. Depending on different needs, steel pipes need to be bent at a certain angle. Traditionally, pipe bending machines are used to bend steel pipes and other tubular materials.

[0003] Traditional pipe bending processes have long been limited by two types of technical bottlenecks. The first is manual pipe bending, which relies on simple tooling operated by manpower and suffers from low efficiency (time per piece > 30 minutes) and poor forming consistency (angle deviation ±5° or more). The second is hydraulic pipe bending technology, which, although it improves power output through hydraulic transmission, still faces problems such as slow response (≥200ms) and coarse deformation control (ellipticity > 10%), making it difficult to meet the needs of high-precision pipe processing. To address the shortcomings of existing technologies, we propose a multi-axis intelligent pipe bending device to solve the above problems. Utility Model Content

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] This utility model discloses a multi-axis intelligent pipe bending device.

[0039] According to the appendix Figure 1-5 As shown, it includes a workbench 1, and a steel pipe 7 is placed on the top surface of the workbench 1.

[0040] See attached document Figure 1-3 The pipe bending mechanism 2 is located on the top surface of the workbench 1. The pipe bending mechanism 2 includes a pipe bending mold 22 and a pipe bending head 23 for bending and positioning the steel pipe 7. A support seat 21 for supporting the pipe bending mold 22 and the pipe bending head 23 is fixedly connected to the top surface of the workbench 1. The transmission mechanism 6 is located inside the workbench 1. The transmission mechanism 6 is used to control the rotation of the pipe bending mold 22. A first gear 24 is fixedly connected to one end of the pipe bending mold 22 extending to the lower part of the support seat 21. A second gear 62 that meshes with the first gear 24 is rotatably connected inside the workbench 1. A pulley 63 is linked to one end of the second gear 62. A motor 64 is fixedly connected to the inner bottom surface of the workbench 1. A connecting belt 65 is provided between the shaft of the motor 64 and the pulley 63. A bracket 61 for supporting the pulley 63 and the second gear 62 is fixedly connected to the inner bottom surface of the workbench 1.

[0041] See attached document Figure 1-2 The booster mechanism 3 is set on the top surface of the workbench 1. The booster mechanism 3 includes a clamp 31 that contacts the outer wall of the steel pipe 7 and a push cylinder 32 that is fixedly set on the top surface of the workbench 1 to drive the clamp 31 to move.

[0042] See attached document Figure 4-5 The sliding mechanism 4 is located on the top surface of the workbench 1, and the top surface of the sliding mechanism 4 is equipped with a clamping mechanism 5 for clamping and fixing the steel pipe 7. See the attached document for details. Figure 4 The clamping mechanism 5 includes a control motor 52 fixedly mounted on the top surface of the sliding clamping table 42 and a tensioning sleeve 51 mounted at one end of the control motor 52 for fixing and clamping the steel pipe 7. The sliding mechanism 4 includes a guide rail 41 fixedly mounted on the top surface of the workbench 1, a sliding clamping table 42 slidably mounted on the outer wall of the guide rail 41 for supporting the clamping mechanism 5, and a combined toothed plate 43, a control gear 44, and a stepper motor 45 for controlling the movement of the sliding clamping table 42. The toothed plate 43 is fixedly mounted on the top surface of the workbench 1. The bottom surface of the sliding clamping table 42 is rotatably mounted with a control gear 44 that meshes with the toothed plate 43. The top surface of the sliding clamping table 42 is fixedly connected with a stepper motor 45 for driving the control gear 44 to rotate.

[0043] The core structure of the multi-axis intelligent pipe bending machine consists of five major modules: bending mechanism 2, boosting mechanism 3, sliding mechanism 4, clamping mechanism 5, and transmission mechanism 6. Based on the different axial directions of the bending mechanism 2, boosting mechanism 3, and sliding mechanism 4, multi-axis bending operations can be performed on the steel pipe 7. The transmission mechanism 6 uses a high-precision servo motor as the power source, forming a flexible connection with the worm gear reducer through pulley 63. This transmission system is specially designed with overload protection; when the working load is abnormal, it can automatically slip, effectively protecting the power components from damage. The worm gear reducer, as the core transmission component, is located inside the support 61. The worm gear reducer drives the pulley 63 to link with the second gear 62. The worm gear reducer is not specifically shown in the attached diagram. The worm gear reducer not only achieves a 90° change in power transmission direction but also completes multi-stage speed regulation of power output through precise meshing, ensuring that the bending die 22 obtains a stable and reliable driving torque.

[0044] The actuator adopts a modularly designed pipe bending device. Its sliding clamping table 42 is driven and fed by a stepper motor 45. The innovatively designed rotary processing platform is driven by an independent servo motor, namely motor 64, which can realize the pipe processing angle adjustment from 0-180°. With the help of the upper computer CNC system, it can accurately perform complex three-dimensional spatial curve pipe bending processing. Compared with traditional manual or hydraulic pipe bending equipment, this device has significant technical advantages. It adopts a fully electric drive scheme, which reduces energy consumption by more than 45%, meeting the GB30253 energy efficiency standard; the processing accuracy reaches ±0.1°, and the repeatability accuracy is improved by 3 orders of magnitude; and there is no hydraulic oil pollution, meeting the requirements of ISO14001 environmental management system.

[0045] Specifically,

[0046] First, the steel pipe 7 is fixed. The steel pipe 7 is placed between the bending mold 22 and the tensioning sleeve 51. By adjusting the position and clamping force of the tensioning sleeve 51, one end of the steel pipe 7 is clamped and fixed. Then, the stepper motor 45 is turned on, so that the stepper motor 45 drives the control gear 44 to rotate. Subsequently, under the meshing of the control gear 44 and the tooth plate 43, the sliding clamping table 42 is driven to slide linearly along the outer wall of the guide rail 41, so that a certain length of steel pipe 7 is placed between the bending mold 22 and the bending head 23, ensuring that the steel pipe 7 will not slip or twist during the bending process.

[0047] The second step is power transmission. After the motor 64 starts, it transmits power to the pipe bending mold 22 through the worm gear reducer, pulley 63, connecting belt 65, first gear 24 and second gear 62 set inside the bracket 61. Then, it pushes the cylinder 32 to extend, so that the clamp 31, which is in contact with the outer wall of the steel pipe 7 at one end, pushes one end of the steel pipe 7 to start rotating.

[0048] The third step is the bending process. As the bending mold 22 rotates and the push cylinder 32 pushes, the steel pipe 7 is gradually bent under the action of the bending mold 22.

[0049] The fourth step is to complete the bending. When the steel pipe 7 is bent to the preset angle or shape, the motor 64 stops and the bending process is completed. At this time, the push cylinder 32 can be controlled to retract, so that the clamp 31 at one end of the push cylinder 32 does not contact the outer wall of the steel pipe 7. The reporter takes out the bent pipe.

[0050] The fifth step is adjustment and replacement. As needed, different specifications of pipe bending molds 22 and pipe bending devices can be replaced to suit steel pipes 7 and other pipe materials with different diameters and wall thicknesses.

[0051] The basic principles, main features, and advantages of this utility model are shown and described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
