Description
Technical field
It is more particularly to a kind of to be used for what thicker strip was sheared the present invention relates to the hydraulic shear technical field of cold rolling thicker strip strip production
Hydraulic shear drive device.
Background technology
In cold rolled strip steel production, when run into it is irregular take the lead magnetic tape trailer or broken belt situation occur when, it is necessary to using hydraulic shear
Cut off irregular strip, hydraulic shear is constituted by fixing cutting edge with shearing cutting edge, during shearing, shearing cutting edge by after driving with fixation
Shearing of the tangent realization of cutting edge to strip.The driving source of hydraulic shear is typically all hydraulic cylinder, but shears demand not according to strip
Together, drive mechanism used in hydraulic shear is also different.In thicker strip production, in order to provide the big shearing force needed for shearing thicker strip,
The hydraulic cylinder of very big specification is often all used, which increases equipment cost, and easily both sides occurs during thicker strip shearing and leads
Asynchronous generation unbalance stress is acted to major gene, the accident of lead fracture is finally resulted in, increases the maintenance cost of equipment.For
Solve above mentioned problem during thicker strip shearing, reduction thicker strip strip production cost and a kind of sheared, it is necessary to invent suitable for thicker strip
Hydraulic shear drive mechanism.
The content of the invention
To solve above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of hydraulic shear sheared for thicker strip
Drive device reduces equipment cost there is provided big shearing force, with uniform force, the characteristics of reducing production cost.
In order to achieve the above object, the technical solution adopted by the present invention is：
A kind of hydraulic shear drive device sheared for thicker strip, includes the hydraulic cylinder 2 of horizontal positioned, the cylinder seat of hydraulic cylinder 2
It is hinged respectively with twisted axis seat 1 and crank block 3 with cylinder head, the other end of crank block 3 is arranged in rotary shaft 7, the two ends of rotary shaft 7 difference
It is connected by two gears 6 with two rack guide pillars 5, rack guide pillar 5 is connected through lower slide 10 with the upper cutter head 12 of upper end；
The lower section of upper cutter head 12, the top of lower slide 10 are respectively arranged with shearing knife edge 11；
Rack guide pillar 5 is provided with guide sleeve 4 with the contact portion of lower slide 10, and guide sleeve 4 is fixed on lower slide 10, with tooth
Bar guide pillar 5 is slidably matched；The described arm of force of crank block 3 is more than the reference radius of gear 6.
It is meshed between described gear 6 and rack guide pillar 5 by the straight-tooth of the bottom of rack guide pillar 5.
The two ends of described rotary shaft 7 are arranged on and are cased with the endoporus of axle bed 9 of axle sleeve 8.
9 points described of axle bed is left and right two, on the basis of being fixed on.
On the basis of described hinged block 1 is fixedly mounted on vertically.
Described rotary shaft 7 is built with flat key.
The beneficial effects of the invention are as follows：
The present invention is more than the reference radius of gear 6, the shearing force quilt that hydraulic cylinder 2 is provided by the arm of force of crank block 3
Drive mechanism is amplified so that can use the hydraulic cylinder 2 compared with small dimension to provide larger shearing force in thicker strip production, and both sides
The engaged transmission of gear 6 and both sides rack guide pillar 5 causes stringent synchronization when both sides rack guide pillar 5 is moved, and greatly reduces rack
The possibility that guide pillar 5 is broken.
Brief description of the drawings
Fig. 1 is the overall structure side view of the present invention.
Fig. 2 is the overall structure front view of the present invention.
Embodiment
Detailed narration is made to the structural principle and operation principle of the present invention below in conjunction with the accompanying drawings.
As shown in Fig. 1 Fig. 2：A kind of hydraulic shear drive device sheared for thicker strip, including twisted axis seat 1, hydraulic cylinder 2 are bent
Handle block 3, guide sleeve 4, rack guide pillar 5, gear 6, rotary shaft 7, axle sleeve 8, axle bed 9, lower slide 10, shearing knife edge 11, upper cutter head
12。
On the basis of hinged block 1 is fixedly mounted on vertically, the horizontal positioned of hydraulic cylinder 2, the cylinder of hydraulic cylinder 2 seat is cut with scissors with twisted axis seat 1
Connect, the cylinder head of hydraulic cylinder 2 is hinged with the one end of crank block 3, the other end of crank block 3 is arranged in rotary shaft 7, built-in flat key is to prevent phase
To rotating, guide sleeve 4 has left and right two, on fixed lower slide 10, is slidably matched with rack guide pillar 5, rack guide pillar
5 points are left and right two, and the top of rack guide pillar 5 is connected with being responsible for the upper cutter head 12 of shearing, and the bottom of rack guide pillar 5 is machined with straight-tooth,
Engaged with gear 6,6 points of gear is left and right two, in rotary shaft 7, built-in flat key is to prevent from relatively rotating, rotary shaft 7
Two ends be arranged on and be cased with the endoporus of axle bed 9 of axle sleeve 8, can be rotated in the endoporus of axle bed 9,8 points of axle sleeve is left and right two,
It is more wear-resisting copper sheathing, 9 points of axle bed is left and right two, on the basis of being fixed on.
The present invention operation principle be：
When thicker strip is sheared, the cylinder head of hydraulic cylinder 2 is released, and drives crank block 3 to rotate, the gear 6 and rotary shaft 7 of both sides turn therewith
It is dynamic, drive the two toothed rack guide pillars 5 engaged with two side gears 6 to be moved downward along guide sleeve 4, the upper slitter being connected with rack guide pillar 5
Seat 12 is fallen, and realizes shearing.Because the arm of force of crank block 3 is more than the reference radius of gear 6, the shearing that hydraulic cylinder 2 is provided
Power driven-mechanism amplifies so that can use the hydraulic cylinder 2 compared with small dimension to provide larger shearing force in thicker strip production, and
The engaged transmission of two side gears 6 and both sides rack guide pillar 5 causes stringent synchronization when both sides rack guide pillar 5 is moved, and greatly reduces
The possibility that rack guide pillar 5 is broken.
