Description
Technical field
The present invention relates to a kind of band steel production equipment, particularly a kind of band steel shear of single hydraulic oil cylinder driving.
Background technology
Traditional mechanical type shear equipment is huge, complex structure, and its application is restricted.Although the hydraulic cutting device of rising in recent years has effectively overcome these problems, exist following shortcoming: one, opening degree is little.When there is serious flatness defect with steel or heap steel accident occurs, cutting edge can be impacted and be peeled off, and affects cutting edge life-span and production efficiency; Two, shear rate is low.Existing hydraulic shear all adopts two oil cylinders to drive, and therefore must be furnished with the parallel that machinery or hydraulic efficiency synchronous mechanism could be realized knife rest, and two cylinders drive and the use of lazy-tongs has limited theoretical shearing number of times; Three, equipment attrition is serious.Hydraulic shear adopts at present flat runner and the contact area between guide plate are large, so the trace of knife rest tilts or distortion will make the frictional force sharp increase of the two even stuck, thereby cause the damage of integral device.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of band steel shear of single hydraulic oil cylinder driving, have that shear blade opening degree is large, shear rate is fast, simple in structure, a little repair and a long feature of service life of equipment.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of band steel shear of single hydraulic oil cylinder driving, comprise two guide pillars 13, one end of guide pillar 13 is inserted in upper tool post 1 also fastening by nut 14, the left and right sides of upper tool post 1 arranges limit journey piece 2, the below of upper tool post 1 is provided with upper scissor blade 3, the other end of guide pillar 13 inserts in sill 8 and by nut 14 closing, sill 8 is connected with lower slide 6 by hinged with it oil cylinder 9, lower slide 6 coordinates with the interlude of guide pillar 13, the top of lower slide 6 is provided with lower tool rest 11, and lower tool rest 11 links together by screw and lower scissor blade 12.
The left and right sides of described lower slide 6 disposes cambered surface slide plate 7, and cambered surface slide plate 7 coordinates with guide plate 5, and together with guide plate 5 puts together on by bolt with frame 10, the top of guide plate 5 is provided with cushion pad 4.
The end face of described cushion pad 4 has stoped the continuation of limit journey piece 2 to decline while contacting with the bottom surface that is arranged on the limit journey piece 2 on upper tool post 1, thereby defines the extreme lower position of upper tool post 1.
The lower end seam of described frame 10 has stoped the continuation of cambered surface slide plate 7 to decline while contacting with the bottom surface that is arranged on the cambered surface slide plate 7 on lower slide 6, thereby defines the extreme lower position of lower slide 6.
Described cambered surface slide plate 7, when lower slide 6 deforms or tilts, is realized cambered surface slide plate 7 along the smooth slip of guide plate 5 by the slight rolling between the cambered surface of cambered surface slide plate 7 and the plane of guide plate 5.
Described upper scissor blade 3 is staight scissors sword.
Described lower scissor blade 12 is oblique cutting edge.
The present invention utilizes single oil cylinder to drive upper tool post simultaneously and lower slide that cambered surface slide plate is housed carries out two moving shearings, without lazy-tongs, has that shear blade opening degree is large, shear rate is fast, simple in structure, a little repair and a long feature of service life of equipment.
Accompanying drawing explanation
Fig. 1 is the three-dimensional installation diagram of the present invention when original state.
Fig. 2 is the structure principle chart of the present invention when shearing condition.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
See figures.1.and.2, a kind of band steel shear of single hydraulic oil cylinder driving, comprise threaded two guide pillars 13 in end, guide pillar 13 adopts alloy forged steel to make, there is all very large features of strength and stiffness, so just guaranteed this with steel shear stability and the reliability in motion and shear history.One end of guide pillar 13 is inserted in upper tool post 1 also fastening by nut 14, and the left and right sides of upper tool post 1 arranges limit journey piece 2, and the below of upper tool post 1 is provided with upper scissor blade 3; The other end of guide pillar 13 inserts in sill 8 and with 14, nut and closes, and sill 8 is connected with lower slide 6 by hinged with it oil cylinder 9.This band steel shear only has a dynamical element oil cylinder 9, therefore without configuration synchronization mechanism, due to control and motion more easy, thereby can reach very high shearing frequency.Lower slide 6 coordinates with the interlude of guide pillar 13.Because upper tool post 1 and lower slide 6 all can move up and down, therefore can realize very large opening degree.The top of lower slide 6 is provided with lower tool rest 11 and lower scissor blade 12, and lower scissor blade 12 is oblique cutting edge, has the little and high feature of shearing area quality of shearing force.The left and right sides of lower slide 6 disposes cambered surface slide plate 7.Between cambered surface slide plate 7 and guide plate 5, for higher pair coordinates, there is the feature that contact area is little and have necessarily for bit function, therefore can guarantee the kinetic stability that single cylinder drives, and can compensate because of long-term and use knife rest distortion or the inclination causing.Together with the guide plate 5 that top is provided with cushion pad 4 puts together on by bolt with frame 10.
Operation principle of the present invention is:
During original state, as shown in Figure 1, oil cylinder 9 is retracted, and cambered surface slide plate 7 drops on the lower end seam of frame 10, and lower slide 6 is in extreme lower position, and upper tool post 1 is in extreme higher position, and it is maximum that opening degree reaches, and without the band steel of shearing, can pass through smoothly.If any band steel, need to shear time, the piston rod of oil cylinder 9 stretches out, due to the suffered piston rod thrust of oil cylinder 9 of lower slide 6 and the opposite direction of self gravitation and motionless.The now cylinder body of oil cylinder 9 promotion sill 8 moves downward, because sill 8 connects as one with upper tool post 1 by guide pillar 13 and nut 14, thereby upper tool post 1 and the superincumbent limit journey piece 2 of installation and upper scissor blade 3 decline thereupon.When limit journey piece 2 drops to while contact with cushion pad 4, upper tool post 1 is in extreme lower position, and upper scissor blade 3 is pushed down and is with steel upper surface.Along with the piston rod of oil cylinder 9 continue stretch out, because moving downward of upper tool post 1 is cushioned pad 4, block, the piston rod of oil cylinder 9 promotes lower slide 6 and moves upward and complete shear action along guide pillar 13.When the piston rod of oil cylinder 9 all stretches out, the lap of upper scissor blade 3 and lower scissor blade 12 is maximum, and this band steel shear is in shearing condition, as shown in Figure 2.
After shearing completes, the piston rod of oil cylinder 9 is retracted, and the cylinder body pulling force of oil cylinder 9 that the integral body that forms due to upper tool post 1, guide pillar 13 and sill 8 is suffered and the opposite direction of self gravitation are and motionless, and now the piston rod of oil cylinder 9 pulls lower slide 6 to move downward.The cambered surface slide plate 7 being arranged on lower slide 6 drops to while contacting with the lower end seam of frame 10, and moving downward of lower slide 6 is prevented from.Along with the continuation of the piston rod of oil cylinder 9 is retracted, the integral body that upper tool post 1 and sill 8 are linked to be by guide pillar 13 is pulled up to extreme higher position by the cylinder body of oil cylinder 9.Now this band steel shear returns to original state, waits for next time and shearing.
