Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a new type of pipe bending machine which is easy to position. Background Art

[0002] A pipe bender is a device widely used in industrial production. It is mainly used to bend various pipes. It has the characteristics of high precision and high efficiency, and can bend pipes into specific shapes and angles according to different needs. A pipe bender is usually composed of a fuselage, a bending die, a drive system and other parts. During operation, by adjusting the position and angle of the die, and controlling the strength and speed of the drive system, precise bending of pipes of different diameters and materials can be achieved. Whether in construction, machinery manufacturing, automobiles, aerospace and other fields, pipe bender plays an important role.

[0003] Prior art includes a utility model with publication number CN219597773U, which discloses a pipe bending machine that facilitates workpiece positioning. The patent uses a workbench with a bending mechanism and a pusher mechanism provided on the top of the workbench. Two second electric push rods are fixedly mounted on the top surface of the workbench, and the output ends of the two second electric push rods are respectively fixedly connected to a U-shaped frame. In the utility model, the second electric push rods are used to drive the U-shaped frame to move up and down, ensuring that the height of the bottom of the U-shaped frame cavity is compatible with the height of the bending die. At the same time, the third electric push rod is used to drive the positioning plate to move so that the positioning plate contacts the side of the pipe, so that the positioning plate limits the position of the pipe to be bent. When the pipe is bent, the positioning plate is used to resist the outside of the pipe. In addition, the third electric push rod is used to drive the positioning plate to move, so that pipes of different outer diameters can be positioned. This solves the problem that the position of the blocking block is fixed, which is not suitable for positioning pipes of different outer diameters, and cannot block the pipe during bending, which may cause harm to workers when the pipe breaks.

[0004] In the daily process of using pipe bending machines to process steel pipes, some existing semi-automatic pipe bending machines require the use of molds to guide the steel pipes during the processing. Since the molds are manually operated during processing, alignment and positioning are required during the operation. Since the alignment and positioning operation steps are relatively cumbersome, the alignment efficiency is low, which in turn leads to the problem of limited processing efficiency. Utility Model Content

Since the mold is manually held and operated during processing, alignment and positioning are required during the operation.

A new pipe bending machine is proposed which is easy to position.
