Abstract
The invention discloses a shearing mechanism of a structural steel cold shearing machine. The shearing mechanism is formed by an upper shear blade and a lower shear blade, a bolt hole and a V-shaped cutting edge are arranged on the upper shear blade and the lower shear blade respectively, a V-shaped groove is arranged between the two adjacent V-shaped cutting edges, the V-shaped groove comprises four upper shear blade V-shaped grooves and three lower shear blade V-shaped grooves, the lower shear blade V-shaped grooves are horizontally arranged, and the upper shear blade V-shaped grooves are arranged in a step mode along the shearing direction. The upper shear blade V-shaped grooves are arranged in a step mode along the shearing direction, the structural steel in the V-shaped groove is cut in a mode from simultaneous cutting to cutting in sequence, a peak value of the shear force is dispersed, accordingly shearing moment impact force is greatly reduced, impact on shearing machine equipment caused by oversize shear force is reduced, service life of the equipment is prolonged, impact current is reduced, production cost is reduced, simultaneously V-shaped cutting edges of the upper shear blade and the lower shear blade vertically align to guarantee each portion of a section breaks simultaneously as far as possible, the section is neat and shearing quality is improved.
Description
Technical field
The present invention relates to cold shears, especially a kind of shaped steel cold shears cutting mechanism reducing large gauge shaped steel cold shears cutting mechanism shearing force, belongs to metallurgical technology field.
Technical background
Shaped steel, after rolling, must cut into the scale of certain length through cold shears operation.Sectional shape is large, and shearing force is large, and when several steel are sheared simultaneously, shearing force is larger.When shaped steel cold shears cutting mechanism is sheared, shearing machine vibrations are large, and the transmission mechanism impact load of shearing machine is large, and lost efficacy fast, and shortened the time between overhauls(TBO), shearing machine body easily loosens distortion, and dash current is large in addition, fragile motor and each component.
On the other hand, because sectional shape is complicated, during shearing, each position of section is in different stress states, the hole type design of cutting edge must consider the difference of each position stress state, give different drafts, ensure that section each several part ruptures as far as possible simultaneously, make section neat.First the pass of cutting edge must ensure shearing quality, and cutting edge hole type design has certain complexity.
Summary of the invention
Object of the present invention, is propose a kind of shaped steel cold shears cutting mechanism, under the prerequisite ensureing shearing quality, reduces shearing force as much as possible, reduce machine utilization.
Technical scheme of the present invention realizes with following method,
A kind of shaped steel cold shears cutting mechanism, be made up of upper scissor blade and lower scissor blade, upper scissor blade and lower scissor blade are equipped with bolt hole and V-arrangement cutting edge, have V-shaped groove between adjacent two V-arrangement cutting edges, V-shaped groove comprises upper scissor blade V-shaped groove and lower scissor blade V-shaped groove, wherein, upper scissor blade V-shaped groove is four, lower scissor blade V-shaped groove is three, and lower scissor blade V-shaped groove is horizontal, and upper scissor blade V-shaped groove is the arrangement of downstairs formula along shear direction.
The difference in height of adjacent two V-shaped grooves of upper scissor blade is at least 2mm.
Bolt hole on upper scissor blade and lower scissor blade is all at least four.
The good effect of technical solution of the present invention is,
Due in the present invention, upper scissor blade V-shaped groove is the arrangement of downstairs formula along shear direction, during shearing, in V-shaped groove, shaped steel is cut off while original, become and cut off successively, shearing force peak value disperses, thus greatly reduces shearing instant impact, reduces because of the excessive impact to cold shears equipment of shearing force, improve service life of equipment, reduce dash current, reduce production cost, simultaneously, the V-arrangement cutting edge of upper lower scissor blade aligns up and down, ensure that section each several part ruptures as far as possible simultaneously, make section neat, improve shearing quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As seen from Figure 1, this shaped steel cold shears cutting mechanism, be made up of upper scissor blade 1 and lower scissor blade 2, upper scissor blade 1 and lower scissor blade 2 are equipped with bolt hole 3 and V-arrangement cutting edge 4, between adjacent two V-arrangement cutting edges 4, have V-shaped groove, V-shaped groove comprises upper scissor blade V-shaped groove and lower scissor blade V-shaped groove, wherein, upper scissor blade V-shaped groove 5 is four, and lower scissor blade V-shaped groove 6 is three, lower scissor blade V-shaped groove 6 is horizontal, and upper scissor blade V-shaped groove 5 is the arrangement of downstairs formula along shear direction.
Be it can also be seen that by Fig. 1, the difference in height of adjacent two upper scissor blade two V-shaped grooves 5 is 2mm.
Be it can also be seen that by Fig. 1, the bolt hole 3 on upper scissor blade 1 and lower scissor blade 2 is four.
