Pressing device is respectively arranged in right rack, pressing device includes support frame, the multiple lower backing rolls being set on support frame, sets
The upper pressing roller being placed in rack, upper pressing roller are at least two groups, and before one group is sheared in cutter head, another group is cut in cutter head
After cutting.
Pressing device is set in the rack of left and right, one group of upper pressing roller of pressing device is before cutter head shearing, and another group
After cutter head shearing, steel band has pressing device to be compressed before shearing and after shearing, pressing device and steel band
Between contacted for roller, do not influence steel band advance, the shape of steel band can be kept not change after compression, shearing when
It waits, steel band is avoided to glance off, especially in the lesser situation of shearing displacement, guarantee shear precision.
Preferred scheme, support frame have the frame body of groove profile, and upward, the lower part of frame body is fixed with clip to the notch of frame body,
Clip has card slot, is connected with reinforcing rib between clip and frame body bottom.Support frame is in groove profile, and lower backing roll is held on support frame
On, support frame trench structure intensity with higher, it is not easy to change, lower backing roll be it is multiple, in shear history, under
The area of support roller support is wider, and support effect is good.
Preferred scheme, frame body is in long strip, and the upper side edge of frame body is provided with lower recess, and lower recess is in U-shape structure, recessed
The bottom of mouth is semicircle.
Preferred scheme, lower backing roll include roll shaft and the roller that is nested on roll shaft and can rotate relative to roll shaft, lower branch
The roll shaft both ends of support roller are mutually fixed with support frame, and the topmost position of all lower backing rolls is in same plane.
Preferred scheme, is connected with two crossbeams between the rack of left and right, and two crossbeams are in the position of upper lower two sides, and two
Support frame is across between two crossbeams.For two crossbeams for support frame to be fixedly mounted, two crossbeams are in the position of upper lower two sides,
Support frame just extends to the position after shearing from the position before shearing in this way, and the support range of lower backing roll is wider,
Just it can also play the role of support when shearing.
Preferred scheme, upper pressing roller are divided into preceding pressing roller and rear pressing roller, and preceding pressing roller is in swing arm structure and can be changed
The distance between lower backing roll, rear pressing roller are stationary structure.
Preferred scheme, preceding pressing roller include rocker, and the front end of rocker is connected with connecting rod, and the lower end of connecting rod is connected with
The tail end of contact roller, rocker is articulated on attachment base, and attachment base is mutually fixed with rack, and telescoping cylinder is equipped on attachment base, is stretched
The telescopic end of cylinder is hinged with rocker.
Preferred scheme, the outer diameter of contact roller are greater than the outer diameter of lower backing roll, the corresponding two adjacent lower branch in the position of contact roller
Support the position between roller.
The beneficial effects of the utility model are: pressing device is set in the rack of left and right, one group of the upper pressing roller of pressing device
Before cutter head shearing, another group is in after cutter head shearing, and steel band has pressing device before shearing and after shearing
It is compressed, is contacted between pressing device and steel band for roller, do not influenced steel band advance, the shape of steel band can be kept after compression
Shape does not change, and when shearing, steel band is avoided to glance off, and especially in the lesser situation of shearing displacement, guarantees shearing
Precision.
