Abstract

The invention relates to a blade gap adjustment mechanism for a plate shearing machine. The blade gap adjustment mechanism comprises a speed reducing motor installed at one side of a rack, a lead screw connected with the output end of the speed reducing motor, and a lower blade base installed on the rack. The two ends of the lead screw are sleeved with nuts. Two fixed inclining blocks are fixedly installed at the lower end of the lower blade base. Each nut is sleeved with one inclining block. The inclining blocks make close contact with the fixed inclining blocks. The horizontal side faces of the inclining blocks are matched with supporting blocks installed on the rack. The blade gap adjustment mechanism is simple in structure; the speed reducing motor drives the lead screw, the lead screw pushes and pulls the nuts, the nuts drive the inclining blocks to move left and right, and the inclining blocks push the fixed inclining blocks to enable the lower blade base and a lower blade to move slightly; meanwhile, by means of the thrust effect of a compressing spring, it is ensured that the fixed inclining blocks and the inclining blocks keep a close contact state constantly, the purpose of fine adjustment of a gap between upper blade and lower blade cutting edges is achieved, adjustment is convenient, and the service life is long.

Description

technical field [0001] The invention relates to a blade gap adjustment mechanism of a shearing machine, which belongs to the technical field of shearing machine equipment. Background technique [0002] The shearing machine is used for the shearing of metal plates. The shearing power of the shearing machine comes from hydraulic transmission or mechanical transmission. When shearing the plate, the upper blade must be adjusted according to the shear strength of the sheared metal plate and the thickness of the metal plate. The gap between the mouth and the edge of the lower blade, and keep the gap uniform. The thicker the sheet metal and the higher the shear strength, the greater the gap between the upper and lower blade edges. When the shearing machine cuts the metal plate, the front end of the metal plate is sent to the stopper reference position of the shearing machine, and then the pressing device presses the metal plate on the back side of the cutting edge of the lower bla...
