Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a rod bending device. Background Art

[0002] In the field of modern mechanical processing, rods are used as basic elements for constructing various mechanical structures and transmission systems. For example, they can be used as transmission components in mechanical transmission systems to transmit related mechanical motion, as components in various supporting structures (such as frames, grids or brackets, etc.) to provide necessary support and stability, or as motion guide components in systems such as molds and sliders to ensure precise linear motion trajectories.

[0003] There are many types of rods, depending on the occasions they are used in and the functions they achieve. For example, they can be divided into straight and curved according to their shapes, and they can also be divided into plastic, metal and other materials according to their materials. In addition to straight rods, curved rods are also widely used in many occasions. Taking the automotive field as an example, the car door lock pull rod currently used to connect the door handle and the lock mechanism and operate the door locking and unlocking is a curved rod, which is crucial to ensure the normal operation of the door lock system and ensure vehicle safety.
