In the prior art, if manual support is needed at one end of the plate and press-bending is performed during the operation of the bending machine, it is indeed necessary to There are some potential safety risks and efficiency issues. Manual support of the plate may cause the operator's hands or other parts of the body to approach the bending area, increasing the risk of injury, especially on high-speed or large-tonnage bending machines. During the bending process, the operator needs to continuously support the plate, which may lead to increased labor intensity. Long-term work may cause fatigue. Manual support and bending need to be performed simultaneously, which limits the production speed, especially in cases where rapid and continuous bending operations are required. To address such problems, the utility model drives the clamping rod to push toward both ends through an air pump to fix the workpiece. When the staff needs to bend the workpiece, the air pump is started to automatically push the clamping rod, thereby reducing direct manual operation of the workpiece and reducing the risk of injury to the operator. The clamping rod is pushed toward both ends, so that the clamping rod drives the clamping block to fix the workpiece, thereby reducing direct manual operation of the workpiece and reducing the risk of injury to the operator.

[0011] Beneficial Effects

[0012] 1. In the prior art, if manual support of one end of the plate is required for bending during the operation of the bending machine, there are indeed some potential safety risks and efficiency problems. Manual support of the plate may cause the operator's hands or other parts of the body to be close to the bending area, increasing the risk of injury, especially on high-speed or large-tonnage bending machines. During the bending process, the operator needs to continuously support the plate, which may increase the labor intensity and cause fatigue after long-term operation. Manual support and bending need to be performed simultaneously, which limits the production speed, especially when rapid and continuous bending operations are required. To address such problems, the utility model drives the clamping rod to push toward both ends through an air pump to fix the workpiece. When the staff needs to bend the workpiece, the air pump is started to automatically push the clamping rod, thereby reducing direct manual operation of the workpiece and reducing the risk of injury to the operator. The clamping rod is pushed toward both ends, so that the clamping rod drives the clamping block to fix the workpiece, thereby reducing direct manual operation of the workpiece and reducing the risk of injury to the operator.

[0013] 2. In the prior art, a press brake or a bending machine usually requires the user to replace the press bending mold with the corresponding angle according to different press bending angles. Each replacement of the press bending mold may take a certain amount of time, which will cause production interruption and affect production efficiency. Frequent replacement of molds may cause mold wear to accelerate, increasing the frequency and cost of mold replacement. To address such problems, the utility model uses a rotator to drive the drive shaft to rotate through an external motor, and at the same time uses the meshing movement of the internal gear set to make the gear housing drive the rotating sleeve to reverse, thereby realizing rapid adjustment of the mold angle and improving the production efficiency of the device.
