Description

Technical Field

[0001] This utility model belongs to the field of CNC pipe bending machine technology, specifically relating to a sorting feeder for a CNC pipe bending machine. Background Technology

[0002] Pipe bends are indispensable connectors in pipeline connections, used to change the direction of pipelines and facilitate transportation. CNC pipe bending machines can perform winding bends on pipes with one or two bending radii in a cold state, and are widely used for bending various pipes and wires in industries such as automobiles and air conditioning. When bending pipes with a CNC pipe bending machine, in order to improve bending efficiency, a feeder is usually set on one side of the CNC pipe bending machine so that the pipes to be bent can be fed into the CNC pipe bending machine in sequence for bending, thereby improving processing efficiency.

[0003] Existing CNC pipe bending machines typically use feeders composed of multiple rollers. These rollers are usually mounted on a bracket and driven to rotate by a motor. When a pipe is placed on the rollers, the rotation of the rollers generates friction, which propels the pipe forward into the CNC pipe bending machine for feeding and bending. However, when bending pipes, most CNC pipe bending machines lack sufficient flexibility in adjusting the bending angle. They often can only perform bending operations according to fixed preset programs and bending mechanical components. When dealing with pipe products with different design requirements, it is necessary to frequently replace some of the bending mechanical components to adjust the bending angle. This operation is not only cumbersome but also time-consuming and labor-intensive, making it quite inconvenient. Utility Model Content
