The continuous production line of the oriented silicon steel strip steel treats the produced edge waste in the shearing process of the disc shear, the device for treating the waste edge is a crushing type waste edge processor, and because of the oriented silicon steel, the unique production process and the yield strength of the oriented silicon steel strip steel are more than 330N/mm2The product of (2) has the problems of continuous waste edge treatment and production bottleneck in the edge cutting production due to the thin material property and thickness. If the speed of the slitter edge treatment machine cannot be well controlled, the speed of the slitter edge treatment machine is low, and the slitter edge is easy to block in the slitter edge treatment machine; the excessive speed of the slitter edge processing machine is too high, and large pulling force can be generated, so that periodically-changed pulling force of the oblique stirring type slitter edge processing machine can be generated when the disc shear shears, and large burrs can be generated at the edge of the sheared strip steel to influence subsequent processes.

Detailed Description
As shown in figure 1, the control method of the crushing type scrap edge processor of the strip steel continuous production line comprises the following steps:
step one, collecting the running speed of the strip steel;
calculating the rotating speed of the crushing type scrap edge processor according to the thickness of the strip steel, the width of the scrap edge of the strip steel and the running speed of the strip steel;
and step three, controlling the operation of the crushing type scrap edge processor according to the rotating speed.
And in the second step, the rotating speed of the stirring type scrap edge treatment machine is calculated according to the following formula:
wherein the content of the first and second substances,
v is converted into the rotating speed of the stirring type waste edge processor,
v0the running speed of the strip steel is the running speed of the strip steel,
h is the thickness of the strip steel,
d is the width of the waste edge of the strip steel:
d is (the width of the strip steel before the slitter edge is sheared-the width of the strip steel after the slitter edge is sheared)/2,
r is the radius of the blade of the stirring type waste edge processor,
l is the length of the cutter shaft of the stirring type scrap edge treatment machine.
The derivation process of equation 1 is described in detail below:
and controlling the crushing type scrap edge processor according to the thickness of the strip steel, the width of the scrap edge of the strip steel and the running speed of the strip steel. The linear velocity of the mincing type slitter edge processor is calculated according to the following formula:
wherein v isaIs the linear speed of the stirring type waste edge processor,
In the invention, the pilot rate of the mincing type scrap edge treatment machine is set as the percentage of the difference value between the linear speed of the mincing type scrap edge treatment machine and the running speed of the strip steel:
the setting of the conductivity directly influences the service life of the equipment and the shearing quality of the disc shear. If the size is too small, faults such as edge blockage, cutter breakage and the like can occur; if too big, not only the on-the-spot noise is very big, produces great environmental pollution, and the speed is too fast moreover and produces shearing force in the limit silk department, and great pulling force in addition, can produce the pulling force of the periodic variation of oblique stirring formula slitter edge processor like this when the disc shear is cuted, and the belted steel limit portion of cutting out can produce great burr, influences subsequent process.
It can be derived from equations 2 and 3:
the on-site control method is mainly realized by controlling the rotating speed of the motor, so that the linear speed of the stirring type waste edge processor is converted into the rotating speed of the stirring type waste edge processor, and the rotating speed of the stirring type waste edge processor is more convenient to control. The rotating speed of the stirring type scrap edge processor is as follows:
equation 1 can be derived from equations 4 and 5.
The invention can acquire the running speed of the strip steel in real time through the acquisition module, input the thickness of the strip steel to be sheared and the width of the waste edge, calculate the proper rotating speed of the stirring type waste edge processor through the computer, and control the rotating speed of the stirring type waste edge processor in real time by the control unit, so that the faults of edge blockage, knife breakage and the like can not occur, and the quality of the edge part of the strip steel can not be influenced by the pulling phenomenon.
