Description
Technical field
The utility model relates to the devices that a kind of flying crank shears prevents shear distortion and piling of steel, belong to metallurgy industry bar
Production equipment technology.
Background technique
Flying shear is the important ancillary equipment of wire and rod continuous rolling production line, for being cut off in workpiece motion s to rolled piece implementation,
Back-end crop, accident are cataclasm and finished product multiple length disjunction shearing.
Flying Shear of Rod Material generally uses flying crank shears, the working method of start stop mode.Referring to attached drawing 1,2,3, flying crank shears
It is cut comprising flying shear upper shearing handle, flying shear lower scissor handle, cutting edge and flying shear, flying shear upper shearing handle and flying shear lower scissor handle are separately mounted to flying shear and cut
On body, flying shear upper shearing handle and flying shear lower scissor handle are equipped with mutually matched cutting edge, and the crank of flying shear is completed to fly by crank up
The shear history cut.In shear history, rolled piece is sheared in a kind of vacant state, when cutting edge shear velocity and milling train
It when small mismatch occurs in the speed of service, often results in not neat at shearing, elbow occurs, not only the quality of steel is caused
It influences, curved steel also often results in rolling line and pushes away steel phenomenon.
Utility model content
The utility model aim, which is to provide a kind of flying crank shears, prevents the device of shear distortion and piling of steel, can be avoided and rolls
There is the phenomenon that elbow and piling of steel when shearing in part, and solves the problems, such as background technique.
The technical solution of the utility model is:
A kind of flying crank shears prevents the device of shear distortion and piling of steel, includes flying shear upper shearing handle, flying shear lower scissor handle, cutting edge
With flying shear shear body, flying shear shear body is equipped with flying shear upper shearing handle arranged up and down and flying shear lower scissor handle, under flying shear upper shearing handle and flying shear
Handle is cut equipped with mutually matched cutting edge, a tubulose eccentric wheel, the tubulose eccentric wheel support are fixed on flying shear lower scissor handle
On rolled piece, tubulose eccentric wheel is equipped with bearing rib.
Arc surface above the tubulose eccentric wheel is supported on rolled piece.
The tubulose eccentric wheel is process by steel plate.
The both ends of the bearing rib are separately fixed on tubulose eccentric wheel and flying shear lower scissor handle.
Using the utility model, when rolled piece enters flying shear by flying shear entrance, the head of rolled piece touches tubulose first
Arc surface above eccentric wheel, the arc surface of tubulose eccentric wheel efficiently reduce the impact to rolled piece, and tubulose eccentric wheel
The arc surface of top supports rolled piece, and rolled piece is kept to be in rolling center line position, when preventing rolled piece from entering race grooved roller road
Piling of steel phenomenon occurs.
The beneficial effects of the utility model are: solving the elbow phenomenon of rolled piece, product quality is improved, while passing through pipe
The support and guidance of shape eccentric wheel have prevented the generation of piling of steel accident when flying shear shearing, have provided for being normally carried out for production
Effect ground guarantees.

Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 4,5,6, a kind of flying crank shears prevents the device of shear distortion and piling of steel, comprising flying shear upper shearing handle 1,
Flying shear lower scissor handle 3, cutting edge and flying shear shear body 4, flying shear shear body 4 are equipped with flying shear upper shearing handle 1 arranged up and down and flying shear lower scissor handle
3, flying shear upper shearing handle 1 and flying shear lower scissor handle 3 are equipped with mutually matched cutting edge, and it is inclined that a tubulose is fixed on flying shear lower scissor handle 3
Heart wheel 2, the tubulose eccentric wheel 2 are supported on rolled piece, and bearing rib 8 is equipped in tubulose eccentric wheel 2.
In the present embodiment, tubulose eccentric wheel 2 is processed into using the steel plate of 12mm thickness, and tubulose eccentric wheel 2 is mounted on
On flying shear lower scissor handle 3, the design of 2 shape of tubulose eccentric wheel will be maintained in crank operation process, the circle of 2 top of tubulose eccentric wheel
Cambered surface is in support screw-thread steel 5 always, is allowed to center line and is overlapped with rolling centerline, only at clipped position, slightly below rolls
Center line, to guarantee that cutting edge completes shear action.
For convenience of installation, tubulose eccentric wheel 2 is processed into the structure of two semicircles, is respectively welded on flying shear lower scissor handle 3, is
The overall stiffness for guaranteeing tubulose eccentric wheel 2, will be under tubulose eccentric wheel 2 and flying shear as bearing rib 8 using the steel plate of 12mm thickness
Cut the connection of handle 3.
Referring to attached drawing 4,5,6, when screw-thread steel 5, which enters 6 mouthfuls by flying shear, enters flying shear, the head of screw-thread steel 5 contacts first
Arc surface to the arc surface of 2 top of tubulose eccentric wheel, 2 top of tubulose eccentric wheel efficiently reduces the impact to screw-thread steel,
And screw-thread steel 5 is supported in the highest point of circular arc, keep screw-thread steel 5 be in rolling center line position, prevent its into
Piling of steel phenomenon occurs when entering to run grooved roller road.
By the supporting role of tubulose eccentric wheel 2, screw-thread steel is made to be no longer on vacant state, flying shear carries out rotary shear
Afterwards, it will not be in and elbow phenomenon occur.Screw-thread steel tail portion is without elbow, it will smoothly enters and runs grooved roller road, screw-thread steel tail
The piling of steel phenomenon in portion also just prevents therewith.
