Description
Technical field
The utility model is related to metallurgy rolling technical field, specifically a kind of steel rolling flying shear blade and its installation fixed knot
Structure.
Background technology
Flying shear is mainly used for middle-size and small-size mill, is set to after mm finishing mill unit, before cold bed entrance, is normally rolling
When, the rolled piece that finish rolling milling train is shut out is cut into the cut lengths for adapting to cold bed length.Multiple length spiral is sheared by flying shear
In production process, due to there are rolling mill speed with flying shear speeds match is not quite identical, there are gap, blades to steel for flying shear gear
The factors such as impact force and back the rollgang abrasion of muscle, the multiple length spiral after shearing, there are the bendings end to end of shearing
Phenomenon causes multiple length spiral lumber recovery too low.
In the above problem, the structure of blade and the mounting structure of blade be cause spiral lumber recovery low reason it
One.The existing blade basil is big, and cutting edge thickness is big, is straight snips mouth, and cutting force is insufficient when shearing, is easy to cause in shear reinforcement
Reinforcing bar deforms, and reduces the straightness of reinforcing bar.
Existing blade mounting means is to be fixedly mounted on the gasket of 5mm and blade on tool apron ontology with two bolts,
Side coil fixes blade, its blade is made to be integrally connected with tool apron ontology.The cutting edge center of upper bottom knife is located at tool apron center line
On, appearance meeting flying shear backlash is excessive after long-term production, this can cause the cutting edge of blade to cause harmful effect to shearing material, drop
Low lumber recovery.
Utility model content
The utility model provides a kind of flying shear blade first, and the basil for solving existing flying shear blade is big, and cutting edge thickness is big,
It is easy to cause reinforcing bar deformation when shear reinforcement, reduces the straightness problem of reinforcing bar.
Technical solution is used by the utility model solves above-mentioned technical problem：Flying shear blade, including blade body, knife
Bolt hole is set on piece ontology, and the basil of blade is 30 °, and the thickness of cutting edge is 2.5~3.0mm, and arc clip is arranged on cutting edge.
It is further：The radius of the arc clip is 95.2mm, action 5mm.
Specifically, the bolt hole is two.
The utility model also provides a kind of flying shear blade installation fixed structure, solves existing flying shear blade installation fixed structure
The problem of it is excessive to occur flying shear backlash after long-term production, reduces lumber recovery.
Technical solution is used by the utility model solves above-mentioned technical problem：Flying shear blade installs fixed structure, packet
Upper cutter head, lower tool apron are included, and is respectively arranged in two blades up and down of upper cutter head and lower tool apron, the sword of the blade on upper cutter head
Towards the front side of the upper cutter head direction of motion, the installation fixed-direction of two blades is opposite at angle；Two blades are above-mentioned side
The cutting edge center of flying shear blade in case, two blades is located on front side of upper cutter head center line.
Specifically, the cutting edge center of two blades is located at 5mm on front side of upper cutter head center line.
It is further：In the lower groove of the upper cutter head, gasket is set on rear side of the traffic direction of blade, lower tool apron it is upper
In groove, backing plate is set on front side of the traffic direction of blade.
Specifically, the thickness of the gasket is 10mm.
The utility model has the beneficial effects that：Since the basil of flying shear blade is small, cutting edge thickness is thin, increases the cutting edge of a knife or a sword of cutting edge
Sharp degree reduces radial cutting force when shearing material, while arc clip being arranged on cutting edge, when changing material cutting by
Power form, reduce material shearing when it is shear-deformable, improve the straightness of material.
The more existing mounting means of flying shear blade that flying shear blade installs fixed structure rotates 180 °, two blades of change
Impact direction, to change cutting edge when shearing material on bottom knife blade stress form, reduce material deformation end to end.Two
The cutting edge center of a blade is located on front side of upper cutter head center line, eliminates because flying shear backlash is excessive, cutting edge is to shearing material not
Profit influences, and ensure that lumber recovery.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model flying shear blade.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the schematic diagram of the utility model flying shear blade installation fixed structure.
Parts, position and number in figure：Blade body 1, bolt hole 11, arc clip 12, upper cutter head 2, lower groove 21,
Gasket 22, lower tool apron 3, upper groove 31, backing plate 32.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, two spiral shells are arranged in blade body 1 for the utility model flying shear blade, including blade body 1
Keyhole 11, bolt hole 11 are used to blade body 1 being mounted on tool apron.The basil of blade is 30 °, and the thickness of cutting edge is
2.5~3.0mm, setting arc clip 12 on cutting edge.The radius of arc clip 12 is 95.2mm, action 5mm.
60 ° of smallers of the basil of the relatively existing conventional blade of the basil of flying shear blade, cutting edge thickness is compared to existing conventional knife
The thickness 5mm of piece is thinner, increases the sharpness of cutting edge, reduces radial cutting force when shearing material.Meanwhile it being set on cutting edge
Arc clip 12 is set to change stress form when material cutting that is, by original straight snips mouth processing camber clip 12, reduce
Material is shear-deformable in shearing, improves the straightness of material.
As shown in figure 3, the utility model flying shear blade installs fixed structure, including upper cutter head 2, lower tool apron 3, and respectively
Two blades up and down of upper cutter head 2 and lower tool apron 3 are installed on by two high-strength bolts, two blades are in above-described embodiment
Flying shear blade.The installation fixed-directions of two blades on the contrary, the basil of blade on upper cutter head 2 towards 2 side of moving of upper cutter head
To front side, the rear side of the basil of the blade on lower tool apron 3 towards 3 direction of motion of lower tool apron.In shear history, 2 He of upper cutter head
The rotation direction of lower tool apron 3 is as shown in the camber line arrow in Fig. 3.The more existing mounting means of blade rotates 180 °, changes two
The Impact direction of blade, to change cutting edge when shearing material above and below blade stress form, reduce material deformation end to end.
In the lower groove 21 of upper cutter head 2, gasket 22 is set on rear side of the traffic direction of blade, in the upper groove 31 of lower tool apron 3,
Backing plate 32 is set on front side of the traffic direction of blade.The cutting edge center of two blades is located at 5mm on front side of 2 center line of upper cutter head, eliminates
Because flying shear backlash is excessive, cutting edge ensures lumber recovery to the adverse effect of shearing material.Flying shear blade installation fixed structure is not necessarily to
Existing equipment is changed greatly, upgrading is easily modified.
