[0002] In the process of wire forming, the bending device plays a very important role in performing precise bending operations on the wire. However, due to different production needs and wire types, different bending diameters are often required. Therefore, the bending device needs to have the ability to quickly adjust the bending diameter to adapt to different process requirements.

[0003] Currently, in many existing technologies, the adjustment mechanism of bending devices is quite complex, often requiring tedious manual adjustments or component replacements to change the bending diameter. This adjustment method is not only time-consuming and labor-intensive, but also affects production efficiency, especially when the bending diameter needs to be changed frequently, which brings inconvenience to the operation.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a cable bending device, which has the following advantages:

[0017] 1. The bending mechanism is designed with hydraulic cylinders driving the connecting plate and hinge plate to ensure the transmission frame slides precisely within the support frame. This allows the bending head to accurately bend the cable according to requirements. The hydraulic cylinders provide powerful force, making the bending process more stable and smooth. The design of the limit rod inserted into the adjustment hole allows for precise control of the relative position of the cable and the bending head, ensuring consistency in bending diameter and bending angle. This design makes the bending mechanism more flexible in operation, improves operational accuracy, reduces human error, and makes cable bending more efficient and accurate.

[0018] 2. The quick-assembly mechanism, through the cooperation of a fixed rod, a fixed sleeve, a rotating rod, and a locking block, enables the rapid installation and stable fixation of various equipment components. The insertion of the fixed rod into the fixed sleeve and the cooperation of the positioning rod and the positioning groove allow for rapid assembly without complex tools. When the rotating rod rotates, it moves the locking block into the groove, thus locking the fixed rod in place and ensuring the equipment remains stable during operation. Furthermore, the return spring, through its tensioning action, enhances the stability of the device and prevents loosening during use, thereby greatly improving the installation efficiency and operational stability of the equipment.

[0019] 3. The quick-release mechanism design allows users to easily disassemble the equipment when needed, greatly improving the convenience and efficiency of operation. By rotating the sleeve to drive the push rod to move, the cooperation between the push rod and the unlocking slot allows the limit sleeve to be unlocked smoothly, releasing the fixation of the locking block. Then, through the action of the tension spring and the return spring, the various components of the device are quickly released. The reset design of the locking block and the rotation of the rotating rod allow the fixing rod to be smoothly separated from the fixing sleeve, ensuring a smooth and jam-free disassembly process. This improves the maintenance efficiency of the equipment and reduces downtime. This design makes the disassembly process quick and convenient, greatly improving the operational flexibility and maintenance efficiency of the equipment. Attached Figure Description

The set of return springs 27 are stretched, pulling the limit sleeve 17 to abut against the outside of the multiple sets of locking blocks 15. At the same time, the multiple sets of tension springs 28 are stretched. The rotating sleeve 29 drives the multiple sets of top rods 30 to move to the bottom surface of the limit sleeve 17.

[0040] When the limiting rod 9 needs to be disassembled, rotating the rotating sleeve 29 drives the multiple sets of top rods 30 to rotate. When the multiple sets of top rods 30 move to the unlocking slot 31 position, they release the contact with the bottom surface of the limiting sleeve 17. The multiple sets of tension springs 28 pull the limiting sleeve 17 to slide and release the contact with the outside of the multiple sets of locking blocks 15.
