Description
Technical field
This utility model belongs to rolling technical field, more particularly, to a kind of new Bar Wire Product flying shearing machine.
Background technology
On the rolling operation line of continuous rolling mill, steel billet becomes after bar through mill milling, and the size of finished product rolled piece is long-range
The length that can receive in cold bed, it is therefore necessary to clipped become the length that cold bed can receive, rolled in the production of bar
Cheng Zhong, is typically cut into the integral multiple that actual user's desired size is scale, this mistake the length of the rod product of upper cold bed
Journey is referred to as double length shearing.Double length shearing can improve lumber recovery, and flying shearing machine are just used to the moving rolled piece of lateral shear, rolling
Highly increase, entrance angle also can increase, and shear knife stress also can increase, result even in when serious and collapse sending out of knife situation
Raw.In order to reduce entrance angle, can be realized by way of increasing the centre-to-centre spacing cutting axle up and down, but the realization of this mode needs
The dimensions of some parts of flying shearing machine to be increased, ultimately results in the increase of equipment overall dimensions.The flying shear of therefore this kind of structure
Machine is conditional to rolled piece thickness, typically inapplicable in the flying shearing machine of wire and rod.
Roll flying shear during domestic bar wire rod is thick and typically adopt crank-linkage type structure, its structure is complex.Linkage
Easily abrasion occurs under shearing impact, and because the abrasion of connecting rod bearing can make blade clearance change, lead under shearing impact
Shearing quality declines, or even device damage, and therefore maintenance workload is larger.Compared with crank-linkage type flying shear, rotational flying shears
No linkage, liner-less, cut hub and directly connect firmly with upper lower drive shaft, structure is simple, reliable.In addition to cutting edge, equipment is several
Maintenance free.But, rotational flying shears also have its shortcoming, that is, in the larger rolled piece of shearing area, due in shears arrangement
Reason, when shears just cut rolled piece, entrance angle is excessive, and the moment of flexure that shearing force applies to shears is excessive, causes breaking of shears.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of new Bar Wire Product flying shear
Machine, the stressing conditions of blade are changed, and can shear the rolled piece of bigger specification, so that the shear ability of shears is carried

Two input shafts stating compound shear body are provided with flywheel respectively, and described input shaft is connected with described flywheel by singly-bound, one
Described flywheel is provided with brake disc, and described flywheel is bolted to connection with described brake disc, and described brake disc both sides are by making
Dynamic device clamping, described compound shear body also includes casing, and two described input shafts are located above described casing, and described casing lower end sets
There is cutting mechanism.
Described shear constitution includes cutting hub on described casing close beneath, described on cut and in the middle part of hub, be provided through institute
State cut hub on cut axle, described on cut axle and be provided with shear blade, described on cut to be provided with down below hub and cut hub, described under cut hub
Middle part be provided through described under cut and cut axle under hub, described under cut axle and be provided with lower scissors piece.
Described upper shear blade, described lower scissors piece can symmetrical opposite direction rotating, described on cut axle, described under cut the center of axle even
Line forms vertical plane, and described upper shear blade and described lower scissors piece are respectively positioned on the same side of vertical plane, and described upper shear blade, institute
State lower scissors piece misaligned with vertical plane.
It is respectively arranged on the left side and the right side entrance below described casing and leads position, outlet guide position, described entrance leads position, described outlet guide
Position is arranged in the entrance and exit of flying shearing machine.
The beneficial effects of the utility model are：Upper shear blade and lower scissors piece are respectively positioned on the same side of vertical plane, and on cut
Blade, lower scissors piece and vertical plane are misaligned, the flying shear of this design can cut up and down axle centre-to-centre spacing constant in the case of, lead to
Cross the shears arrangement changing traditional rotational flying shears, make shears more vertically be also easier to when contacting rolled piece cut rolled piece, very well
Improve the force-bearing situation in the thick rolled piece of shearing for the blade, improve the shear ability that revolution is cut.The force-bearing situation of blade can
To be improved, compared with traditional rotational flying shears, this flying shearing machine can shear the rolled piece of bigger specification, so that the cutting of shears
The ability of cutting is improved.Using bi-motor parallel connection transmission, while providing high torque for flying shearing machine, reduce and act on first
Moment of torsion on level input gear axle, makes the modulus of first order gear pair less, is easy to the structure optimization of shear body.Mair motor passes through drum
Two input shafts of the compound shear body of shape gear coupling direct drive, and compound shear body provides mechanical rigid connection for mair motor
Connect it is ensured that two mair motor reach Complete Synchronization in speed.Flywheel is for energy storage and to provide energy for shearing rolled piece
Carrier, mair motor start boost phase, be the stage of Flywheels energy storage, mair motor flywheel driven is rapidly achieved highest and turns
Speed storage energy, after shearing starts, the flywheel that carries out with shearing gradually reduces rotating speed and releases energy, until rolled piece is cut
Disconnected.This rotational flying shears not only have the advantages that traditional rotational flying shears structure is simple, reliable, maintenance cost is low, and
And also solve the problem that traditional rotational flying shears can not shear big specification blank, improve shear ability and can apply to shear
The larger wire and rod flying shear of section.Function is suitable with crank-linkage type flying shear.Flying shearing machine compact conformation of the present utility model, volume
Little, lightweight, performance has the advantages that shearing area is big, shear rate is high and shearing force is big, big specification rod can be met
The technological requirement of material production line, is more beneficial for large scale rod bar production line Continuous mill train Rolling Production.
