Abstract
The utility model relates to a pair of double blade hydraulic scissors for a narrowband rolling mill, which comprises an upper tool post (1), a lower knife rest (6), a framework (8), a guide rod (3) and a shearing hydraulic cylinder (9); the two sides of the framework (8) have a guide bushing (4); the guide rod (3) is inserted into the guide bushing (4); an upper shearing edge (2) is set on the upper tool post (1); a lower shearing edge (11) is set on the lower knife rest (6); the upper shearing edge (2) is a double shearing edge of T shape; the lower shearing edge (11) is a flat edge; and the shearing hydraulic cylinder (9) drives the upper tool post (1) move up and down along the guide rod (3). According to the utility model, the upper shearing edge is a T-shaped double shearing edge, and two sides shear at the same time when performs shearing; centering effect is performed to strip steel width direction; the whole framework bears symmetrical force and side force of single side shearing won't happen.
Description
Technical field
The utility model relates to hydraulic shear, more particularly, relates to a kind of twolip hydraulic shear for narrow-band rolling mill.
Background technology
The features such as some private steel mills occupy some steel grades consumption markets little, wide in variety in batches in recent years, 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.
In the hydraulic shear design of tradition widestrip mill, the oblique sword of general employing is cut, arrange that 2 are sheared hydraulic cylinder, design gear rackwork is realized and is sheared the synchronous of hydraulic cylinder, and movable cutting edge slides along slideway, 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 when certain width, guarantees shear ability and effect, but because the width of narrow-band rolling mill is less, adopts such structure, just more complicated, and space is nervous, and cost is higher simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of twolip hydraulic shear for narrow-band rolling mill is provided.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of twolip hydraulic shear for narrow-band rolling mill, comprise upper tool post, lower slide, framework, guide rod and shearing hydraulic cylinder, the both sides of described framework arrange fairlead, described guide rod inserts described fairlead, described upper tool post is provided with upper scissor blade, described lower slide is provided with lower scissor blade, described upper scissor blade is the double shear sword that " people " font is arranged, described lower scissor blade is flat sword, and described shearing hydraulic cylinder drives described upper tool post to move up and down along described guide rod.
In such scheme, described shearing hydraulic cylinder is arranged on described base of frame.
In such scheme, described lower slide is fixed on described framework by adjusting bolt.
In such scheme, described framework is provided with swing guide, and described swing guide is hinged on framework.
In such scheme, the side of described lower scissor blade is provided with unsteady guide plate, and the below of described unsteady guide plate is provided with spring.
Implement the twolip hydraulic shear for narrow-band rolling mill of the present utility model, there is following beneficial effect:
1, upper scissor blade is the double shear sword that " people " font is arranged, during shearing, both sides start to cut simultaneously, and strip width direction is had to centering effect, and whole frame stressing is symmetrical, can not produce the side force of one-way shear; Be not subject to the restriction of friction condition between steel plate and cutting edge, cutting edge inclination can suitably increase, and reduces shearing force simultaneously;
2, shear hydraulic cylinder and be arranged in below, as occur oil leakage phenomenon, can not pollute band steel;
3, lower slide adopts adjusting bolt adjusting position, and convenient and easy, the difficulty of equipment adjustment blade clearance reduces greatly.
4, the utility model reasonable in design, effectively reduces and manufactures assembly difficulty and product cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is that the utility model is for the front view of the twolip hydraulic shear of narrow-band rolling mill;
Fig. 2 is that the utility model is for the side view of the twolip hydraulic shear of narrow-band rolling mill.
The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, the utility model, for the twolip hydraulic shear of narrow-band rolling mill, comprises upper tool post 1, lower slide 6, framework 8, guide rod 3 and shears hydraulic cylinder 9.
The both sides of framework 8 arrange fairlead 4, and guide rod 3 inserts fairlead 4, and upper tool post 1 is provided with upper scissor blade 2, and lower slide 6 is provided with lower scissor blade 11.Shear hydraulic cylinder 9 and be arranged on framework 8 bottoms, the ability of shearing hydraulic cylinder 9 meets the summation of the power of two cutting edges.Shear hydraulic cylinder 9 and be arranged in below, as occur oil leakage phenomenon, can not pollute band steel.Upper scissor blade 2 is the double shear sword that " people " font is arranged, lower scissor blade 11 is flat sword, shears hydraulic cylinder 9 and drives upper tool post 1 to move up and down along guide rod 3, completes the process of shearing.During shearing, because both sides start to cut simultaneously, strip width direction is had to centering effect, and the stressed symmetry of whole framework 8, can not produce the side force of one-way shear, be not subject to the restriction of friction condition between steel plate and cutting edge, cutting edge inclination can suitably increase, and reduces shearing force simultaneously.
Lower slide 6 is fixed on framework 8 by adjusting bolt 7, adopts the position of adjusting bolt 7 adjusting lower slides 6, convenient and easy, and as long as the machining accuracy of framework 8 meets, the difficulty of equipment adjustment blade clearance reduces greatly.
Further, be provided with swing guide 10 on framework 8, swing guide 10 is hinged on framework 8.When swing guide 10 is during in level, play the effect with steel guide support, swing guide 10 upset downwards when vertical state in Fig. 2 double dot dash line represent vertical state, the volume that can reduce to take.
Further, the side of lower scissor blade 11 is provided with the guide plate 5 that floats, and the below of the guide plate 5 that floats is provided with spring 12, and the guide plate 5 that floats plays the effect of conduction band, and while shearing steel band, the guide plate 5 that floats is hit and moves down, and spring 12 compressions, play the effect of buffering.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
