Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipe bending machine technology, and in particular to a hydraulic pipe bending machine that is easy to adjust. Background Technology

[0002] A hydraulic pipe bending machine is a mechanical device used for pipe installation. It primarily uses a hydraulic system to bend workpieces. Widely used in the metal processing industry, especially in pipeline laying and repair in power construction, railway and highway construction, boilers, bridges, ships, and decoration, its main features include powerful performance and good stability. It can provide high-pressure power to bend various materials such as steel, copper, and aluminum pipes. Furthermore, the hydraulic system has excellent operational stability, ensuring that the bending machine will not overheat or leak oil during long-term operation, thus guaranteeing the reliability and stability of the equipment. However, existing hydraulic pipe bending machines have certain drawbacks. The bending structure and the main mold body are fixed by bolts or threads during installation, making installation and replacement inconvenient. Adjusting the bending angle is done by changing the position of the arc blocks, but the dimension between two sets of arc blocks cannot be adjusted, resulting in poor flexibility. Therefore, we propose a hydraulic pipe bending machine that is easier to adjust. Utility Model Content
