Description
Technical field
The utility model belongs to metallurgical shearing equipment technical field, and in particular to one kind operates steadily reliable, shearing noise
It is small, shearing quality is high, the steady reliable cold shears oblique line shear knife bottom of shearing of blade life length.
Background technology
Cutter is one kind of lathe, and it uses hydraulic-driven, and security performance is reliable, easy to operate.Cold shears is shearing
The cutter of stocking or rolled piece at room temperature, the maximum shear ability of hot-rolled finished product cold shears are most shearings according to every kind of specification
Radical, as defined in shear temperature.Hot-rolled finished product cold shears machine knife blade is divided into cutter and bottom knife, cutter of the prior art
Blade is curved, therefore cutter blade can only use 2 mouths, and bottom knife blade causes without linear available 4 mouths of radian
Cutter can not overturn mixed up and down with bottom knife during use.The kind majority of such as elder brother's steel Workshop Production is big specification
500MP screw-thread steels, 850t cold shears cutter blades are curved（Fig. 2）, bottom knife edge linear shape, it is substantially in shear-steel
One group of steel is simultaneously disconnected, so shearing vibrations caused by cold shears are big, noise generation load is also just larger, that brings is many unfavorable
Influence.The faults frequent since operation, lower tool rest weld seam often occurs and has shattered, the position such as shear support plate, fuselage fang bolt connects
Loosening is connect, but also the physical and mental health of shearing noise considerable influence worker be present, blade adjustment is frequent, and blade consumption is excessive,
Multiple quality objection occurs for finished product after shearing, and the scram time is more, maintenance cost is high, has a strong impact on being smoothed out for production.
Therefore, it is necessary to be improved to prior art, to ensure product quality, ensure that production is smoothed out.
Utility model content
The purpose of this utility model is to provide one kind and operates steadily that reliable, shearing noise is small, shearing quality is high, the blade longevity
Order long shearing steadily reliable cold shears oblique line shear knife bottom.
What the purpose of this utility model was realized in：Including upper cutter head, cutter, lower tool rest, bottom knife, lathe bed, cut
Mechanism is cut, the cutter is fixedly installed on upper cutter head and is connected with the drive end of cutting mechanism, the bottom knife fixed setting
It is connected in lower tool rest and with lathe bed, the cutting mechanism is fixedly installed on lathe bed, and the blade of the cutter is with respect to bottom knife
For blade along the configuration at an acute angle of blade bearing of trend, the blade of the cutter and the blade of bottom knife are rectilinear edge.
The utility model by by blade of the blade of cutter with respect to bottom knife along the configuration at an acute angle of blade bearing of trend,
To ensure that one group of steel is progressively cut rather than cut in shearing simultaneously, so that the shearing force and impulsive force of cold shears significantly drop
It is low so that shearing is operated steadily, and complete machine vibrations, shearing noise are obviously reduced, and the shearing displacement of every pair of blade is improved up to 25%, blade
Consumption substantially reduces, and shearing quality improves and quality objection reduces by 99%, the reduction of cold shears scram time, maintenance cost
It is obvious to reduce.Therefore, the utility model has spy reliable, that shearing noise is small, shearing quality is high, blade life is grown of operating steadily
