Technical field
This utility model relates to technical field of hydraulic equipment, particularly relates to a kind of hydraulic shearer.
Background technology
Hydraulic shearer is applicable to shear the hot and cold rolled piece blank of plurality of specifications such as square, rectangle or circular cross section, and it is mainly made up of hydraulic cylinder, connecting rod and knife rest, realizes upper dynamic lower cut with the upper and lower knife rest of hydraulic cylinder band movable knife rack and shears. But hydraulic shearer of the prior art is less convenient when shearing paper web, easily there is the phenomenon of skew in paper web. Meanwhile, knife rest can occur abrasion that the phenomenon of skew occurs in the process moved up and down, thus causing that the shear effect to paper web is undesirable.
In view of this, it is necessary to hydraulic shearer of the prior art is improved, to solve the problems referred to above.
Utility model content
The purpose of this utility model is in that to disclose a kind of hydraulic shearer, so that paper web to realize efficient rupturing operation, and prevents knife rest from occurring skew in the process moved up and down.
For achieving the above object, this utility model provides a kind of hydraulic shearer, including: base, framework, is arranged at the hydraulic cylinder on framework and hydraulic control system, and described hydraulic cylinder lower end connects connecting rod, connecting rod is fixing connects a knife rest, the two ends of described knife rest extend in the framework cavities to offering to the inside, and two sides of described knife rest are respectively equipped with press keeping section, and described base is provided with and the depressed part of described press keeping section form fit.
In some embodiments, the cross section of press keeping section is circular arc.
In some embodiments, the axis of depressed part offering blind slot, described blind slot connects with cavities.
In some embodiments, cavities to being respectively provided with bearing to the inside, the side of described bearing and knife rest leans.
In some embodiments, the end, two ends of knife rest is provided with guide post, and the bottom surface of described cavities is provided with the guiding groove being equipped with described guide post, and the directed groove of described guide post is housed.
In some embodiments, the lower edge of knife rest is obliquely installed.
In some embodiments, the lower edge of knife rest is 5 degree with the angle of base.
Compared with prior art, the beneficial effects of the utility model are: pass through this utility model, it is achieved that the efficient rupturing operation to paper web, and be effectively prevented knife rest occur in the process moved up and down skew.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of a kind of hydraulic shearer of this utility model;
Fig. 2 is the partial sectional view of the knife rest in the hydraulic shearer shown in Fig. 1 and framework.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, this utility model is described in detail; but it should what illustrate is; these embodiments are not limitation of the utility model; those of ordinary skill in the art, according to the equivalent transformation in these embodiment institute work energy, method or structure or replacement, belong within protection domain of the present utility model.
Please join a kind of detailed description of the invention of Fig. 1 and a kind of hydraulic shearer of this utility model illustrated in fig. 2. In the present embodiment, this hydraulic shearer, including: base 1, framework 2, it is arranged at the hydraulic cylinder 3 on framework 2 and hydraulic control system 4. Hydraulic cylinder 3 lower end connects connecting rod 5, and connecting rod 5 is fixing connects a knife rest 6. Hydraulic oil is injected in hydraulic cylinder 3 by hydraulic control system 4 by oil pipe (not shown), and drives knife rest 6 to realize rising or descending motion by connecting rod 5.
In the present embodiment, the two ends of this knife rest 6 extend in the framework 2 cavities 21 to offering to the inside, and two sides of described knife rest 6 are respectively equipped with press keeping section 7, and described base 1 is provided with and the depressed part 11 of described press keeping section 7 form fit.
Before paper web is cut off, can in advance paper web be placed in depressed part 11. The cross section of depressed part 11 is circular arc, thus paper web can realize effective collecting, and prevents paper web from moving down at knife rest 6 and offsets in process that it is sheared, the raising cut-out efficiency to paper web. Meanwhile, when knife rest 6 moves down, can by press keeping section 7 set on two sides of knife rest 6 sidepiece of paper web realized against, thus further preventing paper web to occur to offset or displacement in shear history, improve the cut-out efficiency to paper web. Concrete, the cross section of press keeping section 7 is circular arc. The radian of the bottom surface 71 of press keeping section 7 is identical with the radian of depressed part 11, and both radius of curvature are 100cm; Meanwhile, press keeping section 7 also can be tabular.
In the present embodiment, the axis of this depressed part 11 offers blind slot 12, and blind slot 12 connects with cavities 21. When knife rest 6 moves down and cuts off paper web, the lower of this knife rest 6 may extend in this blind slot 12 along 61, paper web to realize rupturing operation thoroughly by this knife rest 6. This blind slot 12 is opened on base 1 and is positioned on the axis of depressed part 11 longitudinal extension.
Cavities 21 to being respectively provided with bearing 22 and bearing 23 to the inside, the side 64 of bearing 22 and knife rest 6 leans, and the side 63 of bearing 23 and knife rest 6 leans. Bearing 22 and bearing 23 by to be configured in cavities 21, and all part protrudes out the side of cavities 21. Concrete, this bearing 22 and bearing 23 can be selected for ball bearing, it is possible to select roller bearing.
The end, two ends of knife rest 6 is provided with guide post 62. The bottom surface 25 of cavities 21 is provided with the guiding groove 24 being equipped with described guide post 62, and the directed groove 24 of guide post 62 is housed. Knife rest 6 is in the process moved up and down, and this guide post 62 can realize sliding under the guiding of guiding groove 24.
By this structure, can be received, by bearing 22 and bearing 23 cutter setting frame 6, the part realization guiding reliably that passage 21 houses in the process that knife rest 6 moves down, and prevent knife rest 6 and framework 2 from colliding and friction, it is effectively prevented knife rest 6 and skew occurs in the process moved up and down, reduce this hydraulic shearer and noise operationally occurs, thus the smooth degree that height equipment runs, improve the service life of equipment.
Meanwhile, the lower of this knife rest 6 is obliquely installed along 61, it is preferred that the lower angle along 61 Yu base 1 of this knife rest 6 is 5 degree. By this be obliquely installed lower to 61, knife rest 6 can be reduced paper web is carried out the resistance in cutting-off process, improve cut-out efficiency.
The a series of detailed description of those listed above is only for illustrating of feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all should be included within protection domain of the present utility model without departing from this utility model skill equivalent implementations of making of spirit or change.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
