Description

A kind of slitting mill efficiently

Technical field

The utility model relates to a kind of shear, in particular to the efficient slitting mill of one.

Background technology

Existing sheet material cutting is mostly to adopt numerical control press and slitting mill to carry out cutting, and the build of numerical control pressGreatly, once be difficult to after installing move. Mould and die accuracy in numerical control press is higher simultaneously, when punching press cutting edge goes wrongTime, need carry out detachable maintaining to numerical control press, not only trouble is also time-consuming.

Present slitting mill is all the cylindrical running roller that adopts upper and lower two equal diameters, fixes hobboing cutter on running roller, logicalCross two running rollers and relatively rotate, the hobboing cutter on running roller carries out cutting to sheet material, and two running roller meetings in the time relatively rotating for a long timeProduce certain centrifugal force, make plate shears otch occur burr, overlap, plastic deformation etc. Simultaneously in the time that hobboing cutter is sheared, everyThe position of inferior shearing is identical, and shearing meeting leaves shearing breach on running roller for a long time, makes the gap between hobboing cutter blade become large,While causing steel band to be sheared, there is plastic deformation, make steel band be not easy to cut off.
