Abstract
The utility model provides a hydraulic steel plate shearing machine capable of shearing in a swinging way, relating to a steel plate shearing machine. At present, shearing machines in service of most mechanical plants are bevel shearing machines which have the drawbacks that due to the large tool travel, the coincidence of the tool is large and the wear of the tool is serious, and the cross section of the sheared steel plate generates large bending deflection so the shearing quality is poor. The two sides of a machine frame are respectively provided with a left oil cylinder and a right oil cylinder which operate synchronously. The piston rods of the left oil cylinder and the right oil cylinder are hinged with two linkages with the same length. The other ends of the two linkages are respectively hinged with a beam and a tool loading platform. The machine frame is hinged with a pull rod, the other end of which is hinged on the tool loading platform and is hinged with the linkages coaxially. Being capable of shearing in a swinging way, the shearing machine has small coincidence and wear with the sheared plates having high quality.
Description
Technical field
The utility model relates to the steel plate shearing machine, particularly a kind ofly can parallelly shear, the hydraulic pressure steel plate shearing machine of the swing shearing of varied angle and varied angle not.
Background technology
At present, most of enginerring works on-line shearing machine mostly is bevel shearing machine.The structure of bevel shearing machine comprises: left and right sides frame, and rack-mounted crossbeam, with the upper slitter platform that frame is slidingly connected by guide rail, the Xia Daotai of fixedlying connected with frame, upper slitter platform descend cutter platform tilt alpha angle-angle of shear relatively.No matter mechanical shear still is a hydraulic pressure is cut, and the motion of upper slitter platform is directly pressurizeed to the upper slitter platform by power set.Bevel shearing machine is because blade trip is big, and cutter coincidence amount when shearing is big, and tool wear is serious; Produced very big flexural deformation in the cross section owing to cut steel plate when shearing, shearing quality is poor.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, but a kind of hydraulic pressure steel plate shearing machine of swing shearing is provided, but this cutter because swing shearing, cutter coincidence amount is little during shearing, not only tool wear is little, and it is good to shear the quality of steel plate.
The utility model is achieved in that
But a kind of hydraulic pressure steel plate shearing machine of swing shearing, comprise: frame, rack-mounted crossbeam, the upper slitter platform that is slidingly connected with frame, the Xia Daotai of fixedlying connected with frame, it is characterized in that: the both sides of described frame are installed the left oil cylinder that is synchronized with the movement, right oil cylinder respectively, the rod hinge connection of the piston rod of left and right oil cylinder and two equal lengths, the other end of two connecting rods is hinged on respectively on crossbeam and the upper slitter platform, also hinged pull bar on frame, the other end of pull bar is hinged on the upper slitter platform, and coaxial hinged with connecting rod.
The attainable shearing pattern of the utility model:
Parallel shearing (angle of shear α=0)
Each cutter design all has certain maximum shear stress, all can use parallel shearing as long as be lower than the steel plate of maximum shear stress thickness.Majority is thin sheet material on manufactory's rolling line, parallel shearing usefulness at most.
During parallel shearing, two oil cylinders are synchronized with the movement, and increase gradually with the angle of hinged two connecting rods of oil cylinder, and connecting rod promotes the upper slitter platform and moves downward, and shearing force is with the variation of leverage angle, and shearing force progressively increases, and until steel plate is cut off, finishes parallel shear action.
The swing shearing of varied angle not
When sheet material surpasses parallel shearing thickness, can adopt the not swing shearing of varied angle.
The swing shearing process of varied angle not: at first select angle of shear α by the material thickness of slab, two cylinders pressurize synchronously then, and connecting rod promotes the upper slitter platform and moves downward, and upper slitter platform pressure process α angle is constant, and after steel plate the right was cut, right oil cylinder quit work also locked.At this moment left oil cylinder continues motion, and the upper slitter platform will be the downward swing shearing in center with the pin joint B of right oil cylinder connecting rod and upper slitter platform, until steel plate is cut off, finishes the not swing shearing action of varied angle.
The swing shearing of varied angle
When steel plate thickness exceeds maximum shear stress, can adopt the swing shearing of varied angle.
The swing shearing process of varied angle: at first left oil cylinder quits work and the pin joint A of left oil cylinder connecting rod and upper slitter platform is locked, right cylinder action, and the upper slitter platform is the center swing with the A point, and steel plate the right is cut, the angle of shear changes with swing.And then the upper slitter platform got back to the home position, and right oil cylinder is quit work and the pin joint B of right oil cylinder connecting rod and upper slitter platform is locked, left cylinder action, the upper slitter platform is the center swing with the B point, and the steel plate left side is cut.Again left oil cylinder is quit work and the pin joint A of left oil cylinder connecting rod and upper slitter platform is locked, right cylinder action, the upper slitter platform is the center swing with the A point, and steel plate is cut off fully.
The utility model is compared with bevel shearing machine and is had the following advantages:
Can adopt swing shearing when 1, shearing, the cutter registration is adjustable to minimum, and shearing quality is best.
2, because the cutter registration is little, so tool wear is little, long service life, and reconditioning is convenient.
3, shearing pattern, opening degree, cutter registration, the angle of shear all can be selected arbitrarily, and flexibility is big.

Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is the schematic diagram of parallel shear history;
Fig. 3 is the schematic diagram of the swing shearing process of not varied angle;
Fig. 4 is the schematic diagram of the swing shearing process of varied angle.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, but a kind of hydraulic pressure steel plate shearing machine of swing shearing comprises: frame 7, and rack-mounted crossbeam 3, with the upper slitter platform 4 that frame is slidingly connected, the following cutter platform 6 of fixedlying connected with frame.The both sides of described frame 7 are installed the left oil cylinder 1-1 that is synchronized with the movement, right oil cylinder 1-2 respectively, the connecting rod 2 of the piston rod of left and right oil cylinder and two equal lengths is hinged, the other end of two connecting rods is hinged on respectively on crossbeam 3 and the upper slitter platform 4, also hinged pull bar 8 on frame 7, the other end of pull bar is hinged on the upper slitter platform 4, and coaxial hinged with connecting rod 2.
The utility model adopts conventional synchro system and general hydraulic electric appliance control system, and is simple in structure, easy to operate.Change cut mode, select the angle of shear, cutter registration, only need to adjust the position of the switch just.
