By technique scheme, described frame is fixed on described support by prestressed draw-bar and nut.
By technique scheme, between described lower cutter platform and frame, be provided with the first copper shoe.
By technique scheme, the head of described piston rod is made circular-arc, and described lower cutter platform is provided with the deep-slotted chip breaker that the head with described piston rod matches.
By technique scheme, described upper scissor blade and lower scissor blade all adopt v-shaped structure.
By technique scheme, described hydraulic cylinder is installed on described support 14, and the side of described hydraulic cylinder is provided with the second copper shoe, and the bottom surface of described hydraulic cylinder is provided with the 3rd copper shoe.
By technique scheme, described in to state frame be 45 degree with the angle at the inclination angle of support formation.
The utility model, there is following beneficial effect: by rack inclining is fixed on support, effectively having dwindled frame takes up space, the limitation that can adapt to on-the-spot installing space, be in tilted layout simultaneously make hydraulic cylinder be no longer positioned at cutting edge under, the not oxidated iron sheet of seal or the cooling water erosion that can prevent hydraulic cylinder cause hydraulic oil to reveal, the equipment loss of avoiding so causing.
As further improvement of the utility model, by adopting prestressed draw-bar fixed frame, can so that frame is born shearing impact, power be large, structural strength, rigidity are large, working stability, reliable.
As further improvement of the utility model, the contact-making surface of piston rod and lower cutter platform is made to arcwall face, can increase the contact area of piston and lower cutter platform on the one hand, the impact of the lateral action power producing while eliminating shearing on the other hand on piston rod, the service life of prolongation hydraulic cylinder sealing element.
As further improvement of the utility model, upper scissor blade and lower scissor blade adopt v-shaped structure, this diagonal shear, can effectively reduce the deflection of section, effectively reduce eave tile, pressure mouth, scuffing, impression, crackle, off-square etc. and shear the incidence of defect, shearing impact is also smaller simultaneously, can avoid stress to concentrate, and improves the life-span of cutting edge.
As further improvement of the utility model, by the side at hydraulic cylinder, copper shoe is set, when needs carry out repair and maintenance to hydraulic cylinder, can hydraulic cylinder be lifted by crane from 45 ° of directions by overhead traveling crane, the piston rod of hydraulic cylinder is directly deviate from along the arcwall face of Xia Daotai, easy and simple to handle, minimizing workman's labour intensity, saves the repair time.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in FIG. 1 to 3, Novel hydraulic shears, comprises frame 6, upper scissor blade 7, lower scissor blade 5, lower cutter platform 3 and hydraulic cylinder 1.Frame 6 frames tilt to be fixed on support 14 by prestressed draw-bar 11 and nut 9, and frame 6 is 45 degree with the angle at the inclination angle that support 14 forms.The top of frame 6 is fixed with upper scissor blade 7, the below of upper scissor blade 7 is provided with lower scissor blade 5, lower scissor blade 5 is fixed on lower cutter platform 3, upper scissor blade and lower scissor blade all adopt v-shaped structure, upper scissor blade 7 is directly incorporated in frame 6 with 8 of high-strength bolts, lower scissor blade 5 is directly incorporated on lower cutter platform 3 with 8 of high-strength bolts, when needs are changed cutting edge, directly bolt is unloaded and old cutting edge can be hung away, after new cutting edge puts in place by bolt again getting togather, and two blade clearances are adjusted to 0-3～0-5mm and directly can rework, easy to operation.The below of lower cutter platform 3 is provided with hydraulic cylinder 1, hydraulic cylinder 1 adopts a large hydraulic cylinder that cylinder diameter is 925mm, for shearing, provide power, overcome pattern that two hydraulic cylinders of tradition the provide shearing force stationary problem in shear history, and the impact producing in shear history is also less, hydraulic cylinder 1 is installed on support 14, and the piston rod 2 of hydraulic cylinder 1 is fixedly connected with lower cutter platform 3, the head of piston rod 2 is made circular-arc, and lower cutter platform 3 is provided with the deep-slotted chip breaker that the head with described piston rod matches.Between lower cutter platform 3 and frame 6, be provided with the first copper shoe 4, the side of hydraulic cylinder 1 is provided with the second copper shoe 10, and the bottom surface of hydraulic cylinder 1 is provided with the 3rd copper shoe 13.
The utility model is that fixed stopping cut, by the accurate off-position of hot prosecution steel billet processed.Before starting to shear, hydraulic shear is in holding state, now the piston rod 2 of hydraulic cylinder is in reset mode, clip is opened completely, and steel billet can pass through smoothly, after steel billet stops under the control of thermometal detector, shearing button on push platform, now hydraulic cylinder 1 rodless cavity oil-feed, piston rod 2 will, by lower cutter platform 3 jack-up under the effect of hydraulic oil, complete shearing.After shearing the piston rod 2 arrival strokes of hydraulic cylinder, cut blank to be cut off completely, now piston rod 2 is got back to fast original position under the effect of hydraulic oil, and an operation cycle finishes.Lower cutter platform 3, in the process of shearing, leads to it with the first copper shoe 4, and the first copper shoe 4 also plays certain supporting role to lower cutter platform 3 simultaneously.The first copper shoe 4 adopts centralized lubrication, regularly lubricated to its contact-making surface.
Consider the actual conditions of shearing blank, cutting edge adopts nichrome tool steel, consider while shearing and will produce huge active force, straight snips sword can produce very large cross section deformation amount, is unfavorable for follow-up rolling, therefore cutting edge adopts v-shaped structure, two working faces are 92 ° of angles, during shearing, can effectively reduce the deflection of section, also can avoid stress to concentrate simultaneously, improve the life-span of cutting edge.And hydraulic cylinder 1 is installed on support 14, the floor space side of hydraulic cylinder is provided with copper shoe, guide plate is installed on support, when needs carry out repair and maintenance to hydraulic cylinder, can hydraulic cylinder be lifted by crane from 45 ° of directions by overhead traveling crane, the piston 2 of hydraulic cylinder is directly deviate from along the arcwall face of Xia Daotai 3, easy and simple to handle, reduce workman's labour intensity, save the repair time.
Consider the steel billet specification of passing through, special install roller additional cutting on body, by gear motor, provide power, so that short base can pass through smoothly.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
