Abstract
The invention discloses an adjusting method of a spiral shearing edge of a roller type flying shear, which is used for observing whether paper is sheared or not by using a popular and easy-to-use method and then adjusting the spiral shearing edge of the roller type flying shear.
Description
Technical Field
The invention relates to a method for adjusting a spiral cutting edge of a roller type flying shear.
Background
With the increasing yield and variety of modern steel production and the fierce market competition, the demand of the shearing machine is increasing continuously as the steel rolling production is required to be developed to a high-speed and continuous production mode.
For a roller type flying shear, an upper roller and a lower roller drive a synchronous gear through a motor to carry out transmission, when an upper roller shaft and the synchronous gear move axially, the upward total degree of the upper roller and the lower roller is restrained, so that the rollers cannot move upwards, and the upper roller and the lower roller generate small displacement due to the relationship of a small spiral angle, thereby adjusting the side clearance of a shear blade. In the spiral shear blade roller flying shear, a shear blade side gap adjusting device is connected with an upper roller, so that the whole roller shaft moves axially, and the movement amount is the same as that of a jack screw rod, thereby realizing the adjustment of the shear blade gap. The adjustment of the clearance can greatly influence the shearing quality of the sheared workpiece and the service life of the roller type flying shear.
Disclosure of Invention

The technical scheme is as follows: in order to achieve the purpose, the invention adopts the technical scheme that:
a method for adjusting a spiral cutting edge of a roller type flying shear comprises the following steps:
(1) opening a pneumatic valve of the roller type flying shear, loosening a braking device, and rotating the roller until the roller is in a shearing position and then stopping;
(2) removing the zero position limit stop of the spiral shear blade and adjusting the clearance to zero position;
(3) closing the pneumatic valve, checking the contact condition of the spiral shear blade, if the clearance of the spiral shear blade is adjusted to zero, but the minimum shear blade side clearance of the spiral shear blade is not 0.6mm, resetting the zero position of the side clearance of the spiral shear blade with an error, and if all the parts are normal, namely the dial indicator is 0.3, performing the step (4);
(4) 3 sheets of A4 paper are overlapped together and placed between the operation side, the transmission side and the middle section of a spiral cutting edge of a roller type flying shear;
(5) opening a pneumatic valve, and rotating a braking device of the roller type flying shear by hand, wherein if the spiral shear blade of the roller type flying shear cannot shear paper sheets in the rotating process, the spiral shear blade needs to be installed again, and the overlapping amount of the spiral shear blade needs to be reset;
(6) if the overlapping amount of the spiral shear blades is increased, the paper cannot be cut, and the gaskets are added on the shearing surfaces of the spiral shear blades for adjustment;
(7) during trial shearing, the spiral shearing blade can cut off the whole piece of paper and completely shear the paper, which shows that the adjustment condition of the side gap of the spiral shearing blade is normal, and the uniformity of the gap of the spiral shearing blade is good at the moment, so that the steel plate can be smoothly sheared;
(8) in the adjustment of the side clearance of the spiral shear blade, the adjustment of the clearance of the spiral shear blade needs to be one-way adjustment, and when the side clearance is adjusted each time, the clearance is adjusted to zero position first, and then the adjustment is continued to an ideal value by the zero position.
The resetting method in the step (5) is as follows:
when the overlapping amount of the spiral cutting edges is reset, each time the overlapping amount is increased by 0.1mm, adjustment is continuously carried out, if the spiral cutting edges can rotate smoothly but paper is not cut, the lateral clearance of the flying shears is reduced, and then trial shearing is carried out; if the paper is only half cut, the upper inclined block, the lower inclined block, the upper pressing block and the lower pressing block of the spiral shear blade roller flying shear are knocked by copper bars, and a bolt is fastened by a spanner until the paper can be completely cut.
The method for adjusting by adding the gasket in the step (6) is as follows:
the paper can not be cut in which area by observing and knowing the paper, and in the area where the paper is cut, the shim is continuously added at the position of the corresponding cutting surface, and the standard shim of 0.05mm is added each time, so that the uniformity of the cutting gap is adjusted until the paper can be uniformly cut.
The invention achieves the following beneficial effects:
the adjusting method provided by the invention can effectively adjust the side clearance and the clearance of the spiral shearing edge, thereby greatly improving the shearing quality of the sheared workpiece and prolonging the service life of the roller type flying shear.
