Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to pipe bending manufacturing equipment. Background Art

[0002] Pipe bending equipment is a mechanical device used to bend metal pipes. Its main function is to bend straight pipes or other shaped pipes into the required shape and angle to meet different engineering and design requirements. The guide structure commonly used in pipe bending machines is usually a disc with an arc groove on the surface. The guidance of the disc can ensure that the pipe is stable during the bending process and guide the pipe to move on the correct path.

[0003] Metal pipes are prone to producing debris during the bending process (for example, if there are tiny cracks, flaws, or uneven coatings on the pipe surface, these defects will be magnified during the bending process, causing the surface to fall off or produce debris. Alternatively, if the pipe bending radius is too small, the material will produce excessive stress during the bending process, especially in the inner bend. This stress may cause the material to break or fall off, thereby producing debris). The debris may form an uneven contact surface between the guide wheel and the pipe, causing the pipe to be unable to maintain the correct position and angle during the bending process. The final bent product may have dimensional deviations or irregular shapes, affecting the processing accuracy. Utility Model Content

A limiting groove 5 is provided on the surface of the guide plate 4. Two rail rods 6 are fixedly connected inside the limiting groove 5. A cleaning assembly 7 is installed on the outer surface of the rail rod 6. The outer surface of the guide plate 4 is provided with tooth grooves 8 at equal intervals.

[0022] The cleaning assembly 7 includes a limit block 72 slidably connected to the outer surface of the rail rod 6. The limit block 72 is arc-shaped. The outer surface of the limit block 72 is inserted into the inside of the limit groove 5 and is slidably connected to the inside of the limit groove 5. The surface of the limit block 72 is penetrated by an arc groove matching the rail rod 6. The outer surface of the rail rod 6 is inserted into the inside of the arc groove. The top of the limit block 72 is fixedly connected to a fixed seat 71. A slide groove 73 is provided inside the fixed seat 71. The inside of the slide groove 73 is slidably connected to a slide plate 74. The outer surface of the slide plate 74 is movably sleeved with a spring 711. The center of the surface of the slide plate 74 is fixedly connected to a connecting column 75. A stepper motor 76 is fixedly installed on the top of the connecting column 75. The output end of the stepper motor 76 is fixed A cylindrical brush 77 is installed, and the length of the bristles on the surface of the cylindrical brush 77 is greater than the depth of the arc-shaped groove on the surface of the guide plate 4. The side of the connecting column 75 is fixedly connected to a connecting plate 78, and the top of the connecting plate 78 is fixedly installed with a servo motor 79. The output end of the servo motor 79 is fixedly connected to a gear 710, the tooth groove 8 and the gear 710 match, and the surface of the servo motor 79 is meshed and connected to the surface of the tooth groove 8. By arranging a cylindrical brush 77 that can rotate around the side on the guide wheel 4, the arc-shaped groove on the surface of the guide wheel 4 can be cleaned before bending the pipe, which can ensure a smooth transition of the pipe during the bending process, reduce surface scratches and uneven defects caused by dirt or scaling in the groove, and thus improve the surface quality of the final product.

[0023] Under normal circumstances, the elasticity of the spring 711 causes the slide plate 74 to slide deep into the interior of the slide groove 73, and the surface of the cylinder brush 77 is pressed against the surface of the guide plate 4. By providing a slide plate 74 that can slide in the slide groove 73, the elasticity of the spring 711 can make the engagement of the gear 710 and the tooth groove 8 more stable, ensuring the stable movement of the cleaning component 7 as a whole, and the elasticity of the spring 711 can also make the surface of the cylinder brush 77 fully contact with the side of the guide wheel 4, thereby improving the cleaning efficiency of the surface of the guide wheel 4 and enhancing practicality.

[0024] Before bending the pipe, the gear 710 is rotated by starting the servo motor 79, and the gear 710 is engaged with the tooth groove 8 to drive the fixed seat 71 to slide inside the limit groove 5. At this time, the cylinder brush 77 moves around the outer side of the guide plate 4. At the same time, the cylinder brush 77 is driven to rotate by starting the stepper motor 76.
