A method for adjusting the stop position after the continuous withdrawal line exits the side shear

Abstract

The invention provides a stop position adjusting method of a continuous annealing line outlet shear after shearing. The adjusting method namely a 'three calibration two adjusting' method is created according to the work principles of the outlet shear. The method includes: sequentially calibrating shear edge stop positions, calibrating the pressure of a pneumatic pressure reducing valve to be 5-5MPa, calibrating the gap of an internal contracting brake to be 2-6mm, using an internal contracting brake spring nut to adjust an internal contracting brake spring, and adjusting the pneumatic reducing valve in a range of 4-7MPa. By the method, an chaotic adjusting process becomes ordered, accurate stop positions after shearing are achieved, adjusting time is shortened, and easy operation is achieved.

Description

technical field [0001] The invention belongs to the field of steel rolling, and in particular relates to the outlet slitting and sampling shears of a continuous annealing production line for cold-rolled silicon steel. Background technique [0002] There is a slitting and sampling shear at the exit of the cold-rolled silicon steel continuous annealing production line. The motor belt drives the flywheel to drive the power. The shearing blade is cut and its position is controlled by the pneumatic clutch and brake. The running strip is blocked, so that the production cannot continue to produce accidents. With the wear of the cutting edge and the change of working conditions, it is common to adjust the stay position of the cutting edge after the side shear is cut. Because the pneumatic pressure relief valve of the side shear, the brake clearance and the brake spring are all adjustable, it is also All have an impact on the position of the side shears. If the adjustment is not goo...

[0002] There is a slitting and sampling shear at the exit of the cold-rolled silicon steel continuous annealing production line. The motor belt drives the flywheel to drive the power. The shearing blade is cut and its position is controlled by the pneumatic clutch and brake. The running strip is blocked, so that the production cannot continue to produce accidents

With the wear of the cutting edge and the change of working conditions, it is common to adjust the stay position of the cutting edge after the side shear is cut. Because the pneumatic pressure relief valve of the side shear, the brake clearance and the brake spring are all adjustable, it is also Both have an impact on the position of the side shears. If the adjustment is not good, the scissors will stay in an inaccurate position after cutting, and accidents will occur.
