Description

Technical Field

[0001] This utility model relates to the field of hardware processing, and in particular to a steel pipe processing bending device. Background Technology

[0002] Steel pipe processing and bending equipment is a core processing equipment in fields such as construction and machinery manufacturing. Its processing specification adaptability, bending accuracy and operating efficiency directly affect the forming quality and production progress of steel pipe components.

[0003] Traditional steel pipe bending devices rely on manual adjustment of the bending angle. This not only makes processing complex angles cumbersome but also increases the risk of accuracy fluctuations and rework due to human error. Some devices lack stable limiting structures, causing the steel pipe to easily shift during bending, further affecting processing quality. These shortcomings make it difficult to meet the needs of processing short pipes of various specifications and with high precision, hindering their ability to meet the requirements of modern manufacturing for efficient adaptation and precise processing, and impacting production efficiency and component reliability.

[0004] Therefore, those skilled in the art have provided a steel pipe processing and bending device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a steel pipe bending device. This device addresses the pain points of time-consuming multi-specification switching, large fluctuations in manual bending accuracy, and cumbersome processing of complex angles in steel pipe processing. Through a multi-size limiting clamp design, it can quickly adapt to different specifications of steel pipes without changing molds, significantly improving the efficiency of specification switching. With the precise linkage between the hydraulic telescopic cylinder and the control system, it can automatically complete multi-angle, high-precision bending, solving the problems of large errors and insufficient repeatability in manual operation. Simultaneously, the steel pipe is stably limited by the limiting wheel, and the automated operation with one-button parameter input simplifies the cumbersome operation process of traditional devices and reduces reliance on worker skills. Its ability to adapt to multi-angle bending of short pipes can efficiently meet the steel pipe processing needs of fields such as construction and machinery manufacturing, achieving rapid and precise processing of multi-specification steel pipes and significantly improving the overall efficiency and professionalism of steel pipe processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A steel pipe processing and bending device includes a base plate, on which a plurality of first hydraulic telescopic cylinders are fixedly mounted, and four second hydraulic telescopic cylinders are fixedly mounted. The end of each second hydraulic telescopic cylinder is fixedly connected to a first mounting top plate. A plurality of first hydraulic telescopic cylinders are fixedly mounted at the bottom of the first mounting top plate. A plurality of fifth hydraulic telescopic cylinders are fixedly mounted on the base plate. A plurality of sixth hydraulic telescopic cylinders are fixedly mounted on the base plate. The end of each sixth hydraulic telescopic cylinder is fixedly connected to a second mounting top plate. A plurality of fifth hydraulic telescopic cylinders are fixedly mounted at the bottom of the second mounting top plate. A plurality of third hydraulic telescopic cylinders are fixedly mounted on the base plate. A plurality of fourth hydraulic telescopic cylinders are fixedly mounted on the base plate. The end of each fourth hydraulic telescopic cylinder is fixedly connected to a third mounting top plate. A plurality of third hydraulic telescopic cylinders are fixedly mounted at the bottom of the third mounting top plate. Through the above technical solution, by setting multiple sets of first, fifth, and third hydraulic telescopic cylinders on the equipment base plate to cooperate with the first, second, and third mounting top plates respectively, a layered multi-specification bending drive system is constructed. Combined with the brackets and limiting rollers on the equipment base plate, a precise positioning and guiding structure for the steel pipe is formed, allowing for direct adaptation to the processing needs of steel pipes of different sizes without changing the mold. The corresponding hydraulic telescopic cylinders are controlled to move in tandem via the control panel. The first, fifth, and third hydraulic telescopic cylinders extend and retract synchronously, driving the corresponding limiting clamps to form a preset bending shape. The second, sixth, and fourth hydraulic telescopic cylinders drive the corresponding mounting top plates to descend, achieving precise bending of the steel pipe. The limiting rollers provide stable positioning of the steel pipe throughout the processing, effectively preventing deviation during bending. The precise linkage of the hydraulic system ensures repeatability accuracy for multi-angle bending, and one-button parameter input simplifies the cumbersome operation process of traditional devices. This structure fundamentally solves the problems of time-consuming specification switching, large manual operation errors, and cumbersome processing of complex angles in traditional bending devices. It can achieve efficient processing of short pipes of multiple specifications without complicated debugging, which not only ensures the stability of steel pipe forming quality, but also significantly improves production and processing efficiency, and is suitable for the diversified processing needs of fields such as construction and machinery manufacturing.

This control panel integrates the control of the first, second, third, fourth, fifth, and sixth hydraulic telescopic cylinders. This achieves precise coordination among the hydraulic telescopic cylinders, simplifies parameter input and operation procedures, ensures bending accuracy and efficiency, and reduces human intervention errors.

[0008] Furthermore, two pairs of brackets are fixedly installed on the base plate of the equipment in front of the first hydraulic telescopic cylinder, the fifth hydraulic telescopic cylinder and the third hydraulic telescopic cylinder; Through the above technical solution, two pairs of brackets are fixedly installed on the equipment base plate, corresponding to the front of the first, fifth, and third hydraulic telescopic cylinders. This forms a support structure for the steel pipe during pushing and processing, providing a foundation for the subsequent installation of the limiting wheel, enhancing the positioning stability of the steel pipe, and helping to improve bending accuracy.

[0009] Furthermore, two limiting wheels are rotatably provided between each of the two opposing supports; The above technical solution involves rotatably installing two limiting rollers between two opposing supports. Utilizing the rotational characteristics of these rollers, the resistance to pushing the steel pipe in is reduced, while simultaneously clamping and limiting the steel pipe from both sides, preventing deviation and wobbling during bending. This provides stable support for precise bending and ensures consistent processing.

[0010] Furthermore, a large-sized limit clamp is fixedly installed at the end of each of the third hydraulic telescopic cylinders; The above technical solution involves fixing a large-sized limit clamp at the end of each third hydraulic telescopic cylinder. This precisely adapts to the shape of the large steel pipe, providing stable support and positioning, and ensuring the forming accuracy and stability of the large steel pipe during bending.

[0011] Furthermore, a medium-sized limit clamp is fixedly installed at the end of each of the fifth hydraulic telescopic cylinders; The above technical solution involves fixing a medium-sized limit clamp at the end of each fifth hydraulic telescopic cylinder. This precisely matches the size of the medium-sized steel pipe, achieving stable support and positioning, and ensuring the accuracy and consistency of the medium-sized steel pipe's bending and forming.

[0012] Furthermore, a small-sized limit clamp is fixedly installed at the end of each of the first hydraulic telescopic cylinders; The above technical solution involves fixing a small-sized limiting clamp at the end of the first hydraulic telescopic cylinder. This precisely matches the specifications of the small-sized steel pipe, providing stable support and positioning, and ensuring the forming accuracy and stability of the small-sized steel pipe during bending.
