Analysis of blade and longitudinal shear form of slitting machine
Longitudinal shear, to achieve a comprehensive and specific understanding, so as to ensure that the product has a good use effect, but also can make it play its due role and function, rather than wasted. Therefore, based on the above learning requirements, the following, will proceed immediately, so that you can save time and improve efficiency.
Blade form in 1. slitting machine
In general, the blades of the slitting machine are:
Parallel blades: that is, the two blades in the vertical shear are parallel to each other, mainly used for transverse shearing, can be sheared material, is a blooming square and slab, and other square or rectangular face of the billet, so this kind of vertical shear can also be called billet shear. In addition, it can also be used for cold shearing. The shape of the blade is suitable for the cross section of the rolled piece.
Inclined blade: of the two blades, the upper blade is tilted, the lower blade is horizontal, so there will be a certain angle, generally speaking, the upper blade tilt range is 1 to 6 degrees. This kind of blade is mainly used to cut steel plate, strip steel, thin slab and welded pipe blank, etc. It can also be used to cut small steel bundles.
2. what are the technical parameters of the slitting machine? Can its configuration be determined according to user needs?
The technical parameters of the vertical shearing machine are the type of equipment, the thickness and width of the plate, the number of longitudinal shearing bars, the shearing speed and the coiling weight, which are all important and basic parameters and are indispensable. As for the configuration of the equipment, it can be selected and determined according to the needs of users.
3. concrete forms of slitting machine
Longitudinal shearing machine is composed of uncoiler, guide device, uncoiler tension device, clamping device, coiler, disc shear, guide roller and looper. Moreover, it has specific forms.
Single entry looper slitting: this kind of slitting machine is to set looper before shearing machine and send it into the belt. Its looper is driven and uncoiling, tension, unwinding and floating roll control. In addition, it can realize slight tension or zero tension shearing to avoid the phenomenon of slippage of the cutting edge. At the same time, the uncoiler can realize alignment on the looper without using alignment device.
Single outlet longitudinal slitting: the difference between it and single entry looper shears is to set looper after shearing. For thin ribbons, a guiding system may be needed at the entrance of the material to avoid uncoiling. And from the present point of view, this form is used more.
Double loop shear: is a combination of inlet loop shear and outlet loop shear two forms, mainly used in cutting strip, suitable for thin and soft strip shear.
