Cold rolled strip resolved cutting flying shear blade primary clearance scaling device and scaling method thereof

Abstract

The invention provides a device and a method for calibrating the initial clearance of cutting edges of flying shears for cutting cold-rolled strip steel, wherein the calibrating device consists of a calibrating plate and a dial test indicator, the calibrating plate is a flat plate with a round through hole; locking screws are arranged on the side faces of the flat plate; the testing lever of the dial test indicator is arranged in the round through hole of the calibrating plate. The calibrating method comprises the following procedures: the dial test indicator is arranged on the calibrating plate and the stylus of the dial test indicator is properly adjusted; the vertical face of the calibrating plate leans tightly against the vertical face of the edge of the flying shear so that the stylusof the dial test indicator touches the vertical face of the edge of the flying shear, and the dial test indicator is set to '0'; the calibrating plate is moved on a same plane to make the stylus ofthe dial test indicator touch the work face of a wedge, and then the value of the dial test indicator 3 is examined; trays of a tray group are adjusted to set the value of the dial test indicator 3 to'0.05', now, the calibrating of the original clearance of edge is finished. The invention has the beneficial effect that the calibrating process is of simple operation, and the tested data is direct,accurate and reliable.

Description

technical field [0001] The invention belongs to the high-speed slitting and flying shear technology of cold-rolled strip steel, in particular to a tool for calibrating the initial gap of the cutting edge of the high-speed slitting flying shear. Background technique [0002] In the prior art, the initial gap of the cutting edge of the high-speed flying shear for cold-rolled strip steel cutting is set to 0.1 mm, and the traditional method for calibrating the initial gap is to check the side with a feeler gauge after assembly. The shortcomings of the traditional detection and calibration method are: the error of the detection result is very large, the repeated detection results often appear contradictory, and the initial clearance of the cutting edge cannot be accurately calibrated. If the initial clearance of the cutting blades is not accurately calibrated, the cutting quality of the flying shears will be affected. In severe cases, some parts of the flying shears will need to ...

Problems solved by technology

The shortcomings of the traditional detection and calibration method are: the error of the detection result is very large, the results of repeated detection are often contradictory, and the initial clearance of the cutting blade is often unable to be accurately calibrated

If the initial clearance of the cutting blades is not accurately calibrated, the cutting quality of the flying shears will be affected. In severe cases, some parts of the flying shears need to be reassembled, and even the calibration of the initial clearance of the cutting blades will be re-calibrated.
