Abstract
A hydraulic locking device is used for hydraulically locking a circle shear box. A cylinder is connected to the box; a cylinder cavity locking strip is connected to the base through a bolt; a cylinder piston is arranged on two sides of the locking strip; a third sealing ring is arranged between the piston and the cylinder; a left cylinder cover and a right cylinder cover are arranged on two ends of the cylinder through a connector; a first sealing ring and a second sealing ring are arranged between the left and right cylinder covers and the cylinder; the front end of the piston and the cylinder cavity are both provided with a positioning stair; a primary oil inlet is arranged in the cylinder; and a cylinder cavity sub-oil path is respectively arranged on the left and right cylinder covers. When the pressure oil enters into the cylinder, the piston and the locking strip are tightly clung so as to generate a locking force which is more than the shearing branch force and efficiently ensure the shear box stable. The invention has simple structure, is capable of automatically processing parts, shortens the producing period and lowers the cost. The assembly is flexible; the structure is compact; and the device occupies less space. The locking piston pairs can be changed correspondingly according to different shearing forces generated by different plates. The expansibility is strong.
Description
Technical field
The present invention relates to the circle shear unit that uses in the cold finish rolling, finishing line of iron and steel and non-ferrous metal industry metal plate and belt, particularly in, metal sheet (the girff hydraulic locking apparatus of 0.2mm～6.0mm).
Background technology
Circle shear is widely used at iron and steel and non-ferrous metal industry as the accurately continuous longitudinal shear equipment of sheet metal strip.Circle shear girff parts are core components of circle shear work, left and right two girffs drive the realization move left and right by precise ball screw on base, satisfy the strip of shearing different in width, after adjusting to the right place, whether its locking at working position is effectively reliable, will directly influence the operational efficiency of the shearing quality and the unit of strip.At present, locking mode commonly used both at home and abroad has following several usually, all comes with some shortcomings:
1, do not increase locking device, only rely on the deadweight of girff, add the locking strength of precise ball screw, overcome and shear the cross component force that strip produced.Only be limited to and shear thin strip, when shearing force is excessive, will cause the girff skew, influence the shearing quality of strip; When shearing force is excessive, make the locking nut of precise ball screw loosening easily, make opening degree adjust precision and reduce, ball screw self is produced damage simultaneously.
2, drive latch segment by oil cylinder and compress girff base plate side.Buying professional oil cylinder has increased cost, orders excessive cycle simultaneously; It is bigger that oil cylinder and retaining mechanism take the device external space.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of hydraulic locking apparatus, is guaranteeing under the effective prerequisite of reliable lock, to realize shortening assembling, maintenance time greatly, saves the purpose of equipment usage space.
For achieving the above object, technical program of the present invention lies in: cylinder body is connected on the girff through connector, the locking strip of inner chamber of cylinder block is connected on the base by screw, piston in the cylinder body is contained in the both sides of locking strip, left side cylinder cap, right cylinder cap are contained in the two ends of cylinder body with connector, be provided with in the cylinder body into, divide oil system, between piston and the cylinder body, between left cylinder cap, right cylinder cap and the cylinder body sealing system is housed all, piston nose and inner chamber of cylinder block all have limited step.
Described to advance, divide oil system be that main oil-in is arranged in the cylinder body, and the branch oil circuit of inner chamber of cylinder block is located at respectively on left cylinder cap, the right cylinder cap.
Described sealing system is that sealing ring three is housed between piston and the cylinder body, and sealing ring one, sealing ring two are housed between left cylinder cap, right cylinder cap and the cylinder body.
After pressure oil entered cylinder body, piston and locking strip were close to, and the coupling mechanism force summation of generation can effectively guarantee the stable of girff greater than shearing component.
The present invention compared with prior art has the following advantages:
1, simple in structure, part all can be made processing by oneself, has shortened the production cycle, has reduced cost;
2, mounting means is versatile and flexible, and compact conformation takies the less equipment space;
3, can be according to the different shearing force of different thicknesss of slab generations, the piston logarithm of corresponding change locking, autgmentability is stronger.
Description of drawings
Fig. 1 is a structure diagram of the present invention;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the present invention mainly is made up of parts such as sealing ring 1, sealing ring 22, left cylinder cap 3, sealing ring 34, piston 5, locking strip 6, right cylinder cap 7, cylinder bodies 8.Cylinder body 8 is connected on the girff 12 through screw, the locking strip 6 of cylinder body 8 inner chambers is connected on the base 9 by screw, piston 5 in the cylinder body 8 is contained in the both sides of locking strip 6, between piston 5 and the cylinder body 8 sealing ring 34 is housed, left side cylinder cap 3, right cylinder cap 7 usefulness connectors are contained in the two ends of cylinder body 8, and sealing ring 1, sealing ring 22 are housed between left cylinder cap 3, right cylinder cap 7 and the cylinder body 8.
Cylinder body 8 by No. 45 steel through heat treatment quenching and tempering to HB245-265, can guarantee its wearability and rigidity, binding face with left cylinder cap 3, right cylinder cap 7 around the cylinder body 8 adopts correct grinding to handle, can effectively prevent the seepage of pressure oil, the endoporus that cylinder body 8 cooperates with piston 5 adopts the machining center right boring to form, guaranteed higher fineness, can effectively prolong the service life of sealing ring 34, sealing ring 1 between cylinder body 8 and the left and right cylinder cap, sealing ring 22 adopt the sealing of O RunddichtringO, guarantee that pressure oil does not leak; The branch oil circuit 11 that is assigned to six inner chamber of cylinder block from main oil-in 10 is located at respectively on left cylinder cap 3, the right cylinder cap 7, and oil circuit only is processed with an oil through on cylinder body 8, guarantee that pressure oil can arrive the inner chamber of cylinder block on both sides simultaneously by left and right cylinder cap, thereby avoided oilhole to intersect at cylinder body 8 inner chambers, in assembling process, when piston 5 is pushed cylinder body 8 inner chambers, can not produce the sealing ring 34 that is contained on the piston 5 and be sheared phenomenon with the perforation mutually of oil circuit by cylinder cavity, when guaranteeing that equipment normally uses, pressure oil can not produce seepage because of the breakage of sealing ring; Sealing ring 34 on the piston 5 adopts the import y-type seal ring, compares the O RunddichtringO, and sealing effectiveness is better; Piston 5 adopts the QT600 material, and higher wearability and intensity are arranged, and piston 5 front ends and cylinder body 8 inner chambers all have limited step, and when guaranteeing pressurized, even locking strip 6 is not installed, piston 5 can not gone out cylinder body 8 outsides yet.After pressure oil entered cylinder body 8, piston 5 tightly fit together with locking strip 6, cylinder body 8 lockings, and the coupling mechanism force summation of generation just can guarantee the stable of girff 12 greater than shearing component.
