Description
Technical field
The utility model relates to the steel rolling field, relates in particular to a kind of rolling-cut double side shear steel plate hold down gag that uses on steel rolling equipment.
Background technology
Adopting rolling-cut double side shear to cut edge on the medium plate production line has been the common recognition of domestic and international metallurgy industry.Rolling-cut double side shear is formed by a plurality of organization's integration of carrying out specific function, thereby finishes the sending to of steel plate in order, compresses, side cut, broken limit, process such as sends.Existing rolling-cut double side shear is as three through-drive rolling-cut double side shears, be respectively arranged with the eccentric shaft of three outs of phase in the main transmission box of this rolling-cut double side shear, wherein have two adjacent eccentric shafts to be respectively homodromal inlet side eccentric shaft and outlet side eccentric shaft, other one is broken limit eccentric shaft.Inlet side eccentric shaft and the outlet side eccentric shaft circular arc blade on left and right sides lever and guide runner transmission upper tool post is done rolling cut with bottom knife and is cooperated, thereby realizes the side cut operation of rolling-cut double side shear; The blade of broken limit eccentric shaft on broken limit lever and the broken limit of guide pad transmission knife rest done to shear with bottom knife and cooperated, to realize the broken limit operation of rolling-cut double side shear.In addition, compressing by the steel plate hold-down mechanism in the rolling-cut double side shear of steel plate realized.
Steel plate hold-down mechanism in the above-mentioned rolling-cut double side shear adopts hydraulic pressure hold-down mechanism or single cam pressing mechanism.The hydraulic pressure hold-down mechanism is to compress steel plate by hydraulic cylinder, and its major defect is that to compress the rhythm of steel plate slower, influences the shearing rhythm of rolling-cut double side shear.For satisfying the requirement of rolling-cut double side shear THE ADIABATIC SHEAR IN rhythm, adopt single cam steel plate hold-down mechanism, as Fig. 1, single cam steel plate hold-down mechanism specifically comprises depression bar, pull bar, lifting spring cylinder, Anchor plate kit and is installed in the cam that compresses on the outlet side eccentric shaft, depression bar is hinged on the header board by bearing pin, depression bar is provided with and compresses the adaptive pinch rollers of cam, and the pull bar two ends are connected with depression bar and Anchor plate kit respectively, and the lifting spring cylinder is connected the pull bar upper end.Wherein, Anchor plate kit comprises lever, and lever one end is connected with pull bar, and the other end is provided with the holddown spring cylinder, and the holddown spring cylinder is connected with pressing plate.The motion process of this hold-down mechanism is: the outlet side eccentric shaft drives and compresses the cam rotation, when the big footpath that compresses cam rotates to the top position, depression bar is around upwards swing of bearing pin, depression bar is pull bar upwards, pull bar by lever to pressing down pressing plate, make this mechanism be in impaction state, this moment, pull bar made the lifting spring cylinder be in most compressed state; When compressing the cam path and rotate to the top position, the lifting spring cylinder force depression bar around bearing pin to lower swing, depression bar is to pressing down pull bar, pull bar makes this mechanism be in the lifting state by the lever tension and compression plate that makes progress, lifting this moment spring cylinder is in the minimal compression shape.
Adopt the major defect of single cam steel plate hold-down mechanism to be: the decrement of lifting spring cylinder medi-spring equals the upper and lower displacement amount of pull bar, when the big footpath that compresses cam rotates to the top position, pull bar moves to highest order, the elastic force maximum of lifting this moment spring cylinder, this force reaction is also finally all born by compressing cam in pull bar, thereby make the load that compresses cam bigger, quickened to compress cam wear; The lifting spring cylinder is in limit compressive state repeatedly, lost efficacy easily, so life cycle is shorter.
The utility model content
The technical problem that the utility model solved is: a kind of rolling-cut double side shear steel plate hold down gag that compresses the cam load that reduces is provided.
