Background technology
In existing aluminium extruding machine, the general defective material adopting after the main scissors vertical shear extruding being fixedly mounted on extruder front-axle beam finishes.In shear history, scissors apparatus stretches out longer, the guiding clearance increasing producing due to the strain of device or along with service time is long, all makes in shear history, and cutting edge has certain yielding, cause defective material to be sheared unclean, in follow-up extrusion process, occur " mushroom head ".
Summary of the invention
The object of the invention is to propose a kind of aluminium extruding machine swing type hydraulic shear and method, in shear history, can make cutting edge keep the trend of drawing close to mould direction, thereby clean cutting off sticks in the defective material on mould always.
Technical scheme of the present invention: a kind of aluminium extruding machine swing type hydraulic shear, is characterized in that: which comprises at least: main scissors oil cylinder, beat defective material cylinder, back shaft, main scissors cylinder support, main scissors oscillating oil cylinder, main scissors guiding frame, slide block, mold pressing device and extruder front-axle beam; Described main scissors cylinder support is fixed on extruder front-axle beam, and main scissors oscillating oil cylinder is fixed on the main scissors cylinder support on press front-axle beam upper surface, and the horizontal one end of main scissors guiding frame is hinged by back shaft and main scissors cylinder support one end; The piston rod of the other end and main scissors oscillating oil cylinder is hinged; The cylinder body of main scissors oil cylinder is fixed on main scissors guiding frame upper end, and the piston rod of main scissors oil cylinder is fixedly connected with slide block, and slide block can slide up and down on the gathering sill of main scissors guiding frame; Described mold pressing device is fixedly connected on the lower end of main scissors frame; Playing defective material cylinder is fixedly connected with slide block.
Described mold pressing device is made up of connecting rod and strip plate.
The swing type hydraulic cutting method that a kind of aluminium extruding machine is used, it is characterized in that: main scissors oscillating oil cylinder is fixed on the main scissors cylinder support on press front-axle beam upper surface, the horizontal one end of main scissors guiding frame is hinged by back shaft and main scissors cylinder support one end; The piston rod of the other end and main scissors oscillating oil cylinder is hinged, main scissors oil cylinder adopts hydraulically powered piston rod dynamic formula structure, in the time carrying out defective material shearing, main scissors oscillating oil cylinder travels forward, drive main scissors guiding frame and main scissors oil cylinder to make mold pressing device press mould by back shaft, slide block slides up and down under the effect of main scissors oil cylinder in main scissors guiding frame, completes shear action.
Advantage of the present invention is: owing to having adopted shuttle-type hydraulic cutter mode, decline and shear in the process of defective material at main scissors, cutting edge is close to mould always and is sheared, and defective material is sheared clean, is beneficial to carrying out smoothly of follow-up extruding.
Brief description of the drawings
Below in conjunction with example figure, the invention will be further described:
Fig. 1 is embodiment of the present invention structural representation front view.
In figure, 1. main scissors oil cylinder; 2. play defective material cylinder; 3. back shaft; 4. main scissors apparatus bearing; 5. main scissors oscillating oil cylinder; 6. main scissors guiding frame; 7. slide block; 8. connecting rod; 9. extruder front-axle beam; 10. mould; 11, strip plate.
Detailed description of the invention
As shown in Figure 1, a kind of aluminium extruding machine swing type hydraulic shear, which comprises at least: main scissors oil cylinder 1, beat defective material cylinder 2, back shaft 3, main scissors cylinder support 4, main scissors oscillating oil cylinder 5, main scissors lead frame 6, slide block 7, mold pressing device and extruder front-axle beam 9; Described main scissors cylinder support 4 is fixed on extruder front-axle beam 9, main scissors oscillating oil cylinder 5 is fixed on the main scissors cylinder support 4 on press front-axle beam 9 upper surfaces, and it is hinged with main scissors cylinder support 4 one end that back shaft 3 is passed through in the horizontal one end of main scissors guiding frame 6; The piston rod of the other end and main scissors oscillating oil cylinder 5 is hinged; The cylinder body of main scissors oil cylinder 1 is fixed on main scissors guiding frame 6 upper ends, and the piston rod of main scissors oil cylinder 1 is fixedly connected with slide block 7, and slide block 7 can slide up and down on the gathering sill of main scissors guiding frame 6; Described mold pressing device is fixedly connected on the lower end of main scissors frame 6; Playing defective material cylinder 2 is fixedly connected with slide block 7.
Mold pressing device is made up of connecting rod 8 and strip plate 11.Under the effect of main scissors oscillating oil cylinder 5, the strip plate 11 on driven mold hold down gag compresses mould 10, and slide block 7 can move up and down, and can make cutting edge and die face keep concordant.
Main scissors oil cylinder 1 adopts hydraulically powered piston rod dynamic formula structure, in the time carrying out defective material shearing, main scissors oscillating oil cylinder 5 travels forward, drive main scissors frame 6 and main scissors oil cylinder 1 to make mold pressing device press mould 10 by back shaft 3, slide block 7 along the gathering sill fast-descending of main scissors guiding frame 6, is sheared defective material under the driving of main scissors oil cylinder 1 hydraulic coupling.In shear history, due to the compression of main scissors oscillating oil cylinder 5, make slide block 7 be close to mould 10 always and decline, thus the quick clean defective material that cuts off.Main scissors guiding frame 6 belongs to techniques well known and is not described in detail here.
Due under main scissors oscillating oil cylinder 5 effects, main scissors oil cylinder 1 and main scissors guiding frame 6 swing back and forth under the support of back shaft 3.When main scissors oil cylinder 1 is worked, be subject to the pressuring action of main scissors oscillating oil cylinder 5, mold pressing device is close on mould 10, thereby while making to shear, slide block 7 is close to mould 10 fast-descendings always.Main scissors oscillating oil cylinder 5 acts on main scissors guiding frame 6 and main scissors oil cylinder 1, make its swing the compression of controlling mold pressing device and mould 10 with separate.
