Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic bending machines, in particular to a hydraulic bending machine with a workpiece fixing mechanism. Background Art

[0002] The hydraulic control system of a hydraulic bending machine is the brain of the bending machine itself. In the production of bending machines, a high rate of automation and standardization is required. Therefore, the hydraulic system is also limited to the hydraulic control method. The different structural types and principles of these methods have been generally recognized by the market.

[0003] For example, a hydraulic bending machine with a workpiece fixing mechanism with the authorization announcement number "CN220406717U" is provided with a limit mechanism to fix the left and right vertical plates to the base. By starting the motor, the motor drives the double-headed screw to rotate, and then the double-headed screw rotates to drive the two clamps to approach each other, so that the two clamps clamp the workpiece and limit the position at the same time, which can avoid the displacement of the workpiece before bending and cause the bending position to shift. When the device is bending the workpiece, the device clamps the workpiece through the clamps on both sides, but when the device is bending, it needs to be pushed from top to bottom by the hydraulic cylinder. However, the device is provided with a double-headed stud at the workpiece processing bending position. When the bending angle is large, the workpiece will be pushed by the hydraulic cylinder to press against the surface of the double-headed stud, which makes the device easy to damage the equipment. At the same time, the device performs a bending operation inside the equipment, so that when the device is bending, it will cause the device to be unable to bend longer workpieces, which makes the device have processing limitations.
