Abstract
The utility model discloses a reusable shear blade for a hydraulic double side trim shear. The shear blade comprises a blade and lug bosses, wherein the blade is of a cuboidal structure with a uniform thickness; the lug bosses are arranged on the left and right sides of the middle position of the blade respectively; each lug boss is of a transverse H-shaped structure; a plurality of bolt holes are uniformly formed in the lug bosses on the two sides; the lug bosses on the two sides are converged at the two ends, and are connected through bolts; the shear blade for the hydraulic double side trim shear is made from 60CrWnSi. The shear blade is simple in structure, high in shock resistance and abrasion resistance and convenient to popularize and use, and can be reused for multiple times, and the production cost is greatly reduced.
Description
Technical field
The utility model belongs to Machining Technology field, is specifically related to a kind of hydraulic type double-side shears cutting edge reusing.
Background technology
At present, the steel plate using on domestic steel plate production line is cut and mostly is rolling-cut double side shear, flywheel crank-type bilateral scissors and hydraulic type double-side shears, but because the power source of rolling-cut double side shear and flywheel crank-type bilateral scissors is all driven by frame for movement, therefore there is the shortcomings such as complex structure, shear ability is on the low side, manufacturing cost and use cost is high.On the contrary, hydraulic type double-side shears obtains people's approval and application gradually with its simple structure, reliable technology and lower cost.But not only cutting edge is expensive for current scissor hydraulic pressure bilateral scissors cutting edge used, 80% needs with import and easily wearing and tearing, long-time use can make trimming quality be difficult to meet high-precision requirement, and for reaching shearing quality, bilateral scissors just must be changed a cutting edge in every 7 days, cause spare parts cost soaring, the restriction that these defects are serious development and the all-round popularization of the scissor bilateral scissors of China's hydraulic pressure.
Application number: the patent document of the 97237342.X applying date: 1997-07-07 discloses a kind of roll-turning double-edge shear blade, the thickness of described blade increases by 1 ~ 7 millimeter, both sides at blade are offered some bolt holes symmetrically, this structure can reduce blade processing and manufacturing surplus, in blade, carry out after cutting at one time, blade both sides are used interchangeably.But longitudinal shock resistance of the disclosed technical scheme of this utility model is still poor, after long-time use, under the effect of shearing force, described bilateral scissors blade inevitably there will be wearing and tearing even to shatter; In addition, the bolt that is arranged on bilateral scissors blade middle part also in use causes certain wearing and tearing in the middle part of blade, and As time goes on, the bolt hole being arranged on blade can increase gradually, the tightness of blade is weakened, have a strong impact on the operating accuracy of hydraulic type double-side shears.
Utility model content
Given this, the purpose of this utility model is to provide a kind of simple in structure, shock resistance the strong and better hydraulic type double-side shears cutting edge reusing of wearability.
A kind of hydraulic type double-side shears cutting edge reusing, comprise blade and boss, described blade is the rectangular structure of equal thickness, the left and right sides in described blade centre position arranges respectively a boss, described boss is horizontal " work " font structure, on the boss of described both sides, evenly offers some bolts hole.
Described both sides boss converges and is bolted together at two ends.
The material of described hydraulic type double-side shears cutting edge is 60CrWnSi.
The beneficial effects of the utility model are: the utility model arranges boss by the left and right sides in the blade centre position at hydraulic type double-side shears; make the utlity model has the thin structure in thick middle both sides; also make the utility model in use there is higher shock resistance; be arranged on the boss of blade both sides when bearing most of longitudinally shaking force; also well protected blade, the service life of having improved blade.In addition, the utility model by arranging bolt hole on boss, and boss converges the structure being bolted on together at two ends, in the middle of being fixed on to two boss firmly, blade clamps, avoided punching in the middle of blade, not only make blade more easily process, and greatly reduce wearing and tearing and the damage of the utility model blade after long-time use.Finally, the structure of described blade not only two all can be used, and the processing of polish after can also all grinding time at blade two ends, removes abrading section, and blade is sandwiched in to continuation use between boss again, greatly improves recycling rate of waterused of the present utility model, reduces costs.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of a kind of hydraulic type double-side shears cutting edge reusing of the utility model;
Fig. 2 is A-A cutaway view of the present utility model;
Fig. 3 is C-C cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3: a kind of hydraulic type double-side shears cutting edge reusing, comprise blade 1 and boss 2, the rectangular structure that described blade 1 is equal thickness, its upper and lower two ends all can be used for shearing.The left and right sides in described blade 1 centre position respectively correspondence arranges a boss 2, described boss 2 is horizontal " work " font structure, described both sides boss 2 converges at two ends and links together by bolt 4, and this structure makes in boss 2 can be wrapped in blade 1 completely.Further, on the boss of described both sides, evenly offer some bolts hole 3, can in bolt hole 3 inside, be screwed into bolt 4 blade 1 is more firmly locked between two boss, for sharing vibratory forces in blade work process, better protect blade 1.In addition, the material of described hydraulic type double-side shears cutting edge is 60CrWnSi, and this material can further improve toughness of the present utility model and life-span.
The utility model is due to any hole not being set on blade 1, therefore easy to process, in addition, described blade 1 not only two ends can successively be used, and blade 1 can be taken off after all grinding time at two ends.Polish and process or remove abrading section, then blade is again sandwiched between boss 2 and is continued to use by bolt 4, greatly improve recycling rate of waterused of the present utility model, reduced cost.
Claims (3)
1. the hydraulic type double-side shears cutting edge that can reuse, comprise blade and boss, it is characterized in that: the rectangular structure that described blade is equal thickness, the left and right sides in described blade centre position arranges respectively a boss, described boss is horizontal " work " font structure, on the boss of described both sides, evenly offers some bolts hole.
