Description
Technical field
The utility model relates to a kind of twolip hydraulic shear for narrow-band rolling mill.
Background technology
The features such as at present, some private steel mills occupy some steel grades consumption markets little, wide in variety in batches, can build narrow-band rolling mill, and it has small investment, it is fast to found the factory, cost is low, have certain competitiveness in market.The hydraulic shear of narrow-band rolling mill is because strip width reduces, and it is also different in structural design cuts in traditional rolling mill hydraulic.The structure of the hydraulic shear of tradition widestrip mill is: 1, according to the value of shearing force, generally adopt oblique sword to cut; 2, conventionally arrange that 2 are sheared hydraulic cylinder, design gear rackwork is realized the synchronous of hydraulic cylinder; 3, movable cutting edge slides along slideway, and corresponding copper shoe need to be joined work according to the requirement of blade clearance, and assembling acquires a certain degree of difficulty.This structure is adapted to widestrip mill, meets in the time of certain width, ensures shear ability and effect, but because the width of narrow-band rolling mill is less, adopts such structure, just more complicated, and space anxiety, and cost is higher simultaneously.
Therefore be necessary to design a kind of novel twolip hydraulic shear, to overcome the problems referred to above.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, provides a kind of shear effect good twolip hydraulic shear.
The utility model is achieved in that
The utility model provides a kind of twolip hydraulic shear, comprises pedestal, and described pedestal is provided with two guide rods; One upper tool post is located at the upper end of two guide rods, and the lower end of described upper tool post is provided with a pair of upper scissor blade, and described a pair of upper scissor blade is chevron shaped; One framework is located on two guide rods, between described framework and described pedestal, is provided with shearing hydraulic cylinder, and described pedestal is provided with lower slide, and the upper end of described lower slide is provided with lower scissor blade, and described lower scissor blade and described a pair of upper scissor blade are just to arranging.
Further, between described lower slide and described pedestal, be provided with lower slide and adjust bolt.
Further, a side of described lower slide is also provided with unsteady guide plate, and the lower end of described unsteady guide plate is provided with spring.
Further, described in each, guide rod is provided with two copper sliding sleeves.
Further, two guide rods be arranged in parallel.
The utlity model has following beneficial effect:
While shearing, described a pair of upper scissor blade and described lower scissor blade start to shear simultaneously, and strip width direction is had to centering effect, and whole frame stressing symmetry, can not produce the side force of one-way shear, and therefore described twolip hydraulic shear has good shear effect.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the twolip hydraulic shear that Fig. 1 provides for the utility model embodiment;
The structural representation at another visual angle of the twolip hydraulic shear that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 2, the utility model embodiment provides a kind of twolip hydraulic shear, for band steel is sheared, it comprises pedestal 4, and described pedestal 4 is provided with two guide rods 2, and wherein two guide rods 2 are set parallel to each other, in this preferred embodiment, described in each, guide rod 2 is provided with two copper sliding sleeves 7, between described pedestal 4 and described two guide rods 2, is connected by described copper sliding sleeve 7, and described copper sliding sleeve 7 can lead in the time shearing.One upper tool post 1 is located at the upper end of two guide rods 2, the lower end of described upper tool post 1 is provided with a pair of upper scissor blade 11, described a pair of upper scissor blade 11 is chevron shaped, and described a pair of upper scissor blade 11 is symmetrical arranged, when shearing, because both sides start to cut simultaneously, strip width direction is had to centering effect, the not restriction of friction condition between tape steel and upper scissor blade 11 simultaneously, the inclination angle of described a pair of upper scissor blade 11 can suitably increase, and refers to that each upper scissor blade 11 and horizontal angle increase, thereby reduces shearing force.
As Fig. 1-Fig. 2, a framework 8 is located at the middle part of two guide rods 2, is provided with one and shears hydraulic cylinder 5 between described framework 8 and described pedestal 4, even if oil leakage phenomenon appears in described shearing hydraulic cylinder 5, can not pollute band steel.Described pedestal 4 is provided with lower slide 3, and the upper end of described lower slide 3 is provided with lower scissor blade 31, and described lower scissor blade 31 is with described a pair of upper scissor blade 11 just to arranging, and described lower scissor blade 31 is flat sword, and it coordinates shearing with described a pair of upper scissor blade 11.Wherein, between described lower slide 3 and described pedestal 4, be provided with lower slide 3 and adjust bolt, for adjusting the position of described lower slide 3, easy to operate.One side of described lower slide 3 is provided with the guide plate 6 that floats, and the lower end of described unsteady guide plate 6 is provided with spring, and in the time of described twolip hydraulic shear shear band steel, described unsteady guide plate 6 can be along with upper tool post is depressed together; Described lower slide 3 opposite sides are provided with manual swing guide 9, while normally work, put, and accommodate, for other equipment provide space for maintenance when overhaul of the equipments.
Described twolip hydraulic shear has following beneficial effect:
1. while shearing, described a pair of upper scissor blade and described lower scissor blade start to shear simultaneously, and strip width direction is had to centering effect, and whole frame stressing symmetry, can not produce the side force of one-way shear, make described twolip hydraulic shear there is good shear effect;
