Packaging steel strip raw material shear used slitting machine

Packaging steel strip materials used slitting shear unit introduction of slitting unit disk shear can be installed on the blade, a steel strip can be cut into strip ( Generally can be up to more than 10) 。 Hot rolled strip steel slitting as article number depends on the ability to shear equipment. Disc cut back with coiler tension device and finished products, with a certain tension during winding and tensile stress value of 5 - 20 mpa, the type of tensioning device such as roller or pressure plate type. In addition, there are often set in front of the coiler cutting scissors to cut the strip, thus saves when points cut large steel roll to wear a belt. After the finished coiler, has special ejecting equipment, used to remove the string of narrow strip steel coil. Before discharge roll, steel roll on the drum, along the circumferential direction must be tied, especially thick strip steel coil. Slitting unit has designed without looping ( Namely, & other Pull cut & throughout; ) 。 Before and after cutting in disc set loop, can make the strip automatic centering and make the segmentation more than after the strip is easy to separate, but due to the existence of looping both increase the length of the unit, and to bring the disc cut after wearing work to increase difficult. No looping slitting machine, except to overcome the above shortcomings, but also increases shear rate of the unit. Looping before cutting, the strip with rocker, due to lose the ability to self centering, therefore, require the use of floating type of decoiler; After cut without looping, to realize synchronous operation unit, generally USES & other Pull cut & throughout; Way, that is, in the process of shearing, disc scissors or not only dish don't drive power, to make up for the shortage of the coiling tension. The winding tension is synthesized from uncoiling and shear resistance, so the proper proportion of power allocation among. Cut disc drive, in order to reduce the wear of cutter head, cutter circumference speed slightly higher than the strip movement speed. In addition, on the reel should be separated roller and other facilities, to control the tension of each strip, achieve ideal shearing quality and winding quality.
