How do you set a guillotine shearing machine blade?

The specific method to adjust the blade clearance of the plate shear is to adjust the blade clearance of the plate shear with a single stroke, At that time, it is necessary to loosen the locking screw temporarily. When the blade of the upper plate shear descends to the lower dead center, quickly turn the ball valve to close the oil circuit, make the upper tool holder of the plate shear stop at the lower dead center, and then lock the screw.
Then continue to open and close the ball valve slightly to make the upper knife rest of the plate shear rise section by section in the whole stroke. At this time, measure the evenness of the blade edge clearance of the plate shear section by section, and check whether the blade edge clearance of the plate shear is adjusted properly,
Adjust and turn on the plate shearing machine for several cycles of shearing, and try to cut plates of different thicknesses from thin to thick. After ensuring that there are no abnormal conditions, turn the handle to the required scale value.
The ball valve is used to measure the uniformity of the upper and lower edge clearance of the blade of the plate shear. Whether the edge clearance of the blade of the plate shear is appropriate or not is an important factor affecting the shear quality and prolonging the service life of the blade.
