Problems solved by technology

When the shear gap is too small to cut metal materials, it will cause chipping and fragmentation of the movable blade and the fixed body blade; when the shear gap is too large to cut thin and soft metal materials, it will cause failure to cut or even block the movable blade In the middle of the fixed blade, causing the deformation of the movable body and the fixed body
Multiple times of "rolling and shearing" between the movable body blade and the fixed body blade will cause wear and deformation of the movable body and the moving body transfer shaft, resulting in early failure

Abstract

The invention relates to the field of metal pull-down shearing pliers, in particular to a shearing clearance adjusting device for the metal pull-down shearing pliers. The shearing clearance adjusting device comprises a movable body, a fixed body and a movable body transloading shaft. A supporting body is fixedly arranged on the outer side of the movable body, a screw type clearance adjusting base is arranged on the supporting body, and a screw type clearance adjusting column is arranged inside the screw type clearance adjusting base. The end, close to the movable body, of the screw type clearance adjusting column is sleeved with a copper abrasion-resistant ring, the copper abrasion-resistant ring is in contact with the movable body, and the screw type clearance adjusting column and the screw type clearance adjusting base are positioned by a positioning mechanism. According to the shearing clearance adjusting device for the metal pull-down shearing pliers, the screw type clearance adjusting column can make axial displacement movement through four-direction positioning rotation, hence, the copper abrasion-resistant ring is driven to push the movable body to make axial movement, the adjusting clearance formed between the copper abrasion-resistant ring and the movable body is changed, and thus the shearing clearance between a movable blade and a fixed blade can be adjusted.

Description

technical field [0001] The invention relates to the field of pliers used for demolition and shearing metal, in particular to a device for adjusting the cutting gap of pliers for demolition and shearing metal. Background technique [0002] The pliers used for demolition and shearing metal should deal with different hardness, thickness and shear strength of metal materials during the cutting operation. The sharpness of the demolition shear blade should be adjusted according to the principle of metal shearing. The movable blade equipped with the movable body and the fixed body should be adjusted The shear gap between the fixed blades installed. When the shear gap is too small to cut metal materials, it will cause chipping and fragmentation of the movable blade and the fixed body blade; when the shear gap is too large to cut thin and soft metal materials, it will cause failure to cut or even block the movable blade In the middle of the fixed blade, the deformation of the movabl...
