The bending machine designed based on the thought can offset the resilience of the metal plate by adjusting the bending angle of the bending knife, does not need to bend gradually, can bend to a required angle at one time, and has small equipment floor area.
Furthermore, because when the upper pressing block and the lower pressing block compress the metal plate body, the bending knife applies force to the side face of the metal plate, and the elasticity of the metal plate can lead the upper pressing block and the lower pressing block which compress the metal plate to bear larger rebound force, so that the metal plate is easy to damage or loosen. In order to solve the problem, the rebound resilience of the metal plate is overcome by the upper pressing block and the lower pressing block in the form of the inclined arc-shaped surface, and when the bending knife bends the metal plate, the rebound resilience of the metal plate is prevented from further extruding the upper pressing block and the lower pressing block, so that the service life of the upper pressing block and the lower pressing block is prolonged.
Still further, in order to improve the stability of the upset of the bending knife, a chain-type driving mechanism is selected, and the chain is meshed with the sprocket on the knife body, so that the knife body of the bending knife is driven to move along the arc-shaped guide rail, and therefore the stability of the movement of the bending knife can be still kept under the state of large bending counter force, and the mode of improving the processing precision is also provided.
Furthermore, in order to be suitable for bending metal plates with different thicknesses, the bending tool utilizes the characteristic of the wedge-shaped surface, the tool body and the tool body are in butt fit through the wedge-shaped surface, and the horizontal movement of the tool body relative to the tool body is further converted into the height change of the tool body so as to be suitable for bending the metal plates with different thicknesses. And because the wedge-shaped surface is a continuous inclined surface, the adjustment precision of the adjustment mode is higher. And further, the horizontal movement of the cutter body relative to the cutter body is reciprocating, whether the cutter body is heightened or lowered is determined according to different conditions, and the cutter body can rotate along with the cutter body in the bending process. In order to simplify the driving mode of the cutter body, the cutter body is driven to move by the driving piece, the driving piece only needs to move horizontally, the cutter body is sleeved on the driving piece, and the cutter body is driven to lift relative to the cutter body by the horizontal movement of the driving piece.
