When the device is working, the driver drives the swing arm to rotate, the swing arm drives the X cam and the Y cam to rotate, the X follower and the Y follower respectively drive the X upper knife and the Y upper through the X wedge and the Y wedge. The knife moves to adjust the shearing gap between the X upper knife and the Y upper knife and the lower knife. Driven, as the equipment is used over time, the X-direction transmission mechanism and the Y-direction transmission mechanism will have different aging problems, resulting in inconsistent adjustment gaps between the X upper knife and the Y upper knife when the driver is working, which will eventually affect the right-angle shear. Shearing accuracy

The invention discloses a right-angle cutting machine upper and lower knife clearance adjusting mechanism in the field of right-angle cutting machine. The right-angle cutting machine upper and lower knife clearance adjusting mechanism comprises an upper knife base, the upper knife base is provided with an X upper knife and a Y upper knife, and the upper knife base is provided with a guide column. A guider is arranged on the upper knife base. A wedge base is arranged on the upper part of the guide column, a wedge is arranged on the wedge seat, a guide seat is arranged on the guider, a support plate is arranged on the guide seat, and a linear motor is mounted on the guide seat. The output end of the linear motor is hinged to a connecting rod, the other end of the connecting rod is hinged to a driving plate, the driving plate is hinged to the guider and hinged to a push rod, and the push rod is provided with a wedge block. The wedge block is close to the wedge, the movement track of the push rod is perpendicular to the angular bisector of an included angle formed by an X arm and a Y arm. A first flexible locking mechanism is arranged between the upper knife base and the guider. A second flexible locking mechanism is arranged between the guide seat and the wedge seat. A guide mechanism is arranged between the upper knife base and the guider. The right-angle cutting machine upper and lower knife clearance adjusting mechanism can accurately adjust clearance between the upper knife and the lower knife of the right-angle cutting machine.
Description
technical field [0001] The invention belongs to the field of right-angle shears, in particular to a mechanism for adjusting the gap between upper and lower knives of a right-angle shear. Background technique [0002] The scissor tool includes an upper knife and a lower knife. The upper knife is connected to the upper knife seat, the lower knife is connected to the lower knife seat, and the upper knife seat is connected to the slider. The downward movement of the slider drives the upper knife to move down. The upper knife and the lower knife The knife cooperates to cut the sheet. Due to the influence of factors such as the thickness of the sheet metal, it is necessary to adjust the shearing gap between the upper knife and the lower knife. [0003] In the prior art, there is a blade gap adjustment device for right-angle shears, its patent application number: 201020247333.1; application date: 2010.07.05; announcement number: CN 201720514 U; announcement date: 2011.01.26; its s...
