Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a fully automatic pipe bending machine for pressure pipe fittings. Background Art

[0002] Pressure pipelines are a type of equipment commonly used in the chemical and power industries to transport materials. The main feature of pressure pipelines is their complex structure, which places high demands on on-site installation work. At present, finished pipe fittings (such as elbows, tees, reducers, etc.) are often used for small-diameter pipes to achieve changes in the direction or diameter of the pipeline. For large-diameter pipelines, or structures where the direction changes at a specific angle in the design, it is necessary to make some welded elbows according to actual conditions during on-site installation. This type of elbow is made by cutting straight pipes, the shape changes are discontinuous, welding is difficult, and the presence of welds increases the uncertainty of the quality of the pipe fittings.

[0003] The utility model with publication number CN218744156U discloses a pressure pipe on-site bending and forming device, including a chassis, one side of which is provided with two fixed electric rollers arranged in an isosceles triangle and a movable electric roller moving in a vertical direction, the two fixed electric rollers are arranged side by side on the same horizontal plane, and the movable electric roller is arranged above the two fixed electric rollers.

[0004] As shown in the above-mentioned utility model, the existing on-site bending forming device for pressure pipes generally calculates the curvature radius of the bending pipe by utilizing the principle of three-point circle determination, and can adjust the curvature of the formed bending pipe according to the scale on the spiral pressure rod; different grooves are processed on the rollers to meet the forming requirements of pipes of different diameters. Although different grooves can adapt to pipes of different diameters to a certain extent, the notches on them make the pressure pipe easy to deform when bending, affecting the quality of the pressure pipe, and the existing bending rollers are fixed, which is not convenient for quick replacement according to the needs of different diameters.
