Description
Technical field
The present invention relates to the cutting system of band, be especially by wind for coiled strip form band shearing cut out be divided into width
Meet the apparatus system of the narrowband of market demands.
Background technique
Band is provided by upstream equipment milling train, cleaning line equipment, it is however generally that, market user's required band when using
Width it is smaller and width is different, it is narrowband that this, which just needs the wider band of supplied materials cutting cutting, completes the cutting cutting and appoints
The equipment of business is circle shear or is that roller is cut, and cutting ring is exactly correspondingly arranged on upper and lower rotor, and band passes through between two cutting rings
When cut out and separated.Since the width of raw band volume is usually determining, and the strip width that downstream client needs is different,
So coiled strip band is disposably generally cut cutting at least two bands in order to improve the utilization rate of stock roll and processing efficiency
Material, this will correspond to configuration at least two groups cutting ring, situations such as according to customer requirement and tool wear, replacement on upper and lower rotor
Cutter becomes more frequently, realizes the quick positioning of cutting ring and locking is to realize the key factor of equipment high efficiency rate production.More
The serious is, arrange that multiple groups cutting ring requires the axial length of deflector roll longer on rotor, according to beam type structure by rotor
It is mounted on the rack, the winding degree variation after necessarily causing overhanging section to accept power everywhere is huge, for high-precision thin wall type copper
For matter band, cutting cuttings more than two cuttings is then difficult, i.e. nothing between two cutting rings in the cutting ring group far from rack
Method realizes reliable and stable shearing cooperation.
Summary of the invention
The object of the present invention is to provide circle shear and control systems, it is ensured that realize the cutting cutting of at least two slit strips,
Meet reliable shearing cooperation, reliably opens rack, while improving cutter changing efficiency.
To achieve the above object, the present invention is the following technical schemes are provided: a kind of circle shear, including rack and is arranged in rack
On upper and lower rotor, rack includes fixed frame and moving frame, and one end rotary type of upper and lower rotor is arranged in fixed frame
On, it is detachable rotation connection between the other end and moving frame of upper and lower rotor, upper and lower rotor constructs identical, upper rotor
Including mandrel, the outer shaft being nested on mandrel, the setting tensioner of upper rotor free end is constituted between tensioner and upper rotor
Circumferential limit, axial displacement cooperation, there are circumferentially spaced block, end face of the block towards fixed frame in the periphery of tensioner
Perpendicular to axial direction and be in the same plane, moving frame along upper and lower rotor axial displacement, moving frame be equipped with it is upper,
The bearing holder (housing, cover) of lower rotor free end adaptation, bearing holder (housing, cover) are installed on the bearing socket being supported on moving frame by bearing, bearing holder (housing, cover)
Outer end retaining ring is set, be circumferential limit, axial movement cooperation, inner wall last week of retaining ring between retaining ring and moving frame
To spaced apart baffle is arranged, block passes through from the idle area between baffle when block and baffle misplace, block
It is turned to both when concordant with the inner side end of baffle and is opposite to each other position, tensioner is kept off when being displaced to side where fixed frame
The inner side end of block and baffle reclines and drives side displacement where the circumferential fixed frame of locking, and the outer end face of retaining ring is pressed on
On the end face of cutter ring pads.
By adopting the above technical scheme, the end face of retaining ring and cutter ring pads is driven to offset by tensioner to realize cutting ring
Quickly positioning and locking, reliably open and close rack, replace cutting ring and adjust the spacing distance of every group of cutting ring in time.

It is detachable rotation connection between one end and moving frame 20, the upper and lower construction of rotor 30,40 is identical, and upper rotor 30 includes core
Axis 31, the outer shaft 32 being nested on mandrel 31 are constituted circumferential between the tensioner 33 and rotor 30 of the setting of 30 free end of rotor
There are circumferentially spaced block 331 in limit, axial displacement cooperation, the periphery of tensioner 33, and block 331 is towards fixed frame 10
End face perpendicular to axial direction and be in the same plane, axial displacement of the moving frame 20 along upper and lower rotor 30,40, moving machine
Frame 20 is equipped with the bearing holder (housing, cover) 21 being adapted to upper and lower rotor 30,40 free ends, and bearing holder (housing, cover) 21 is supported on movement by the installation of bearing 22
On bearing socket 23 in rack 20, retaining ring 50 is arranged in the outer end of bearing holder (housing, cover) 21, is between retaining ring 50 and moving frame 20
Circumferential limit, axial movement cooperation, are circumferentially arranged spaced apart baffle 51 on the inner wall of retaining ring 50, block 331 with support
Block 331 passes through from the idle area between baffle 51 when block 51 misplaces, and the inner side end of block 331 and baffle 51 is flat
It is turned to both when neat and is opposite to each other position, block 331 and baffle 51 when tensioner 33 is displaced to 10 place side of fixed frame
Inner side end recline and retaining ring 50 driven to be displaced to 10 place side of fixed frame, the outer end face of retaining ring 50 is pressed on cutter
On the end face of ring pads, to realize the quick positioning and locking of cutting ring;When needing replacing cutting ring, tensioner 33 is to far from fixed branch
The displacement of 10 place side of frame, both block 331 and baffle 51 turn to when missing one another position block 331 between baffle 51
Idle area pass through, fixed frame 10 is separated with moving frame 20, to realize the quick-replaceable of cutting ring.
Further, inner hole is that the small-bore section of the tensioner 33 of stepped hole is socketed on mandrel 31 and is arranged between the two
Seal assembly 311a, 311b, setting end cap 312 between the large aperture section and mandrel 31 of tensioner 33, the step surface of tensioner 33,
The annular region A and hydraulic circuit A1 surrounded between the inner face of end cap 312, the large aperture section of tensioner 33 and mandrel 31 connects
Logical, hydraulic circuit A1 is connected with the first solenoid valve.Hydraulic circuit A1 to annular region A injection hydraulic oil drive tensioner 33 to
The displacement of 10 place side of fixed frame;When hydraulic circuit A1 oil return, drive tensioner 33 to separate from the compression spring on mandrel 31
The displacement of 10 place side of fixed frame.
Further, be arranged between the both ends of outer shaft 32 and mandrel 31 sealing element 313a, 313b and sealing element 313a,
