Problems solved by technology
[0003] However, when some thicker sheet metal parts are being bent, they are prone to breakage during the bending process. Due to the moment of breakage, the bending device will move upwards, and the position of the fracture is very easy to scratch the bending device. One side of the plate will cause some damage, thereby reducing the service life of the bending device, and the bending device cannot be rotated at a certain angle to avoid the crack at the moment the plate breaks

The invention discloses a protection device for plate bending machining. The protection device comprises a downward pressing device and a bending device, wherein a telescopic plate is installed in an inner cavity of a first telescopic groove, a balance weight device is installed in an inner cavity of a top plate, a balance weight chamber is formed in the side close to the balance weight device, a rolling ball is placed at the upper end of an inclined panel, a ball outlet hole is formed in one side of the upper end of an inner cavity wall of the balance weight device, so that the rolling ball can roll out of the ball outlet hole, and due to the fact that the gravity of the inner cavity of the top plate changes, the top plate can rotate towards one side. According to the protection device, an air pressure assembly is installed on one side of the inner cavity wall of the balance weight chamber, an upward ejecting assembly is installed on the bottom face of the inner cavity of the balance weight chamber, impact force of the rolling ball pushes a baffle installed on one side, and a push plate moves towards one side so that the air in an inner cavity of an air pressure chamber can be rapidly inflated into an inner cavity of the upward ejecting assembly from a second air pipe, the air can quickly push an airtight plate to rise, and the airtight plate pushes an inclined plate installed at the upper end after rising.
Description
technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a protection device for sheet bending processing. Background technique [0002] Sheet metal is a kind of metal commonly used in various production and processing. When processing sheet metal, it needs to be processed by bending machine so that sheet metal can meet different processing requirements. Bending machine is a kind of A machine capable of bending sheet metal parts. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The seat shell, the coil and the cover plate are composed, the coil is placed in the depression of the seat shell, and the top of the depression is covered with the cover plate. [0003] However, when some thicker sheet metal parts are being bent, they are prone to breakage during the bending process. Due to the moment of br...
