Background Art

A steel plate bending machine is an important equipment used for processing metal plates. It bends the metal plates into the desired shape by applying force. The working principle of the bending machine is mainly to provide power through a hydraulic system and be controlled by an electrical system to achieve the closing and separation of the upper die and the lower die, thereby completing the bending of the metal plate. Chinese utility model patent CN220515236U discloses a steel plate bending machine, including a bending machine body, both side surfaces of the bending machine body are fixedly installed with a fixed structure near the rear position, and the fixed structure is divided into two groups, and both side surfaces of the bending machine body are fixedly connected with a clamping structure near the front position.

When the above-mentioned bending machine is used, if there is no bending groove on the surface of the bent steel plate, the steel plate is placed inside the bending machine. Since it is not fixed and limited, the steel plate is easy to move due to its own toughness. If the steel plate is directly clamped and fixed, the position of the steel plate will change as the bending progresses, causing the clamping parts to interfere with it, affecting the bending work.

The beneficial effects of the utility model are as follows:

The utility model realizes that the pressing plate moves downward synchronously with the moving end of the bending clamp. When the bending clamp contacts the steel plate and starts to bend, the pressing plate contacts the rotating mechanism at the same time. The bending part of the steel plate is pushed downward by the bending clamp, causing its height position to continuously change. The synchronous downward movement of the rotating mechanism makes its rotation axis consistent with the bending part. Therefore, when the rotating mechanism drives the clamp to rotate, it can ensure that the clamp clamps and fixes the steel plate, assists in stabilizing the bending, and does not interfere with the movement of the steel plate, thereby affecting the bending work.
