Description
Technical field
The utility model relates to a kind of hydraulic means that is used for the angle adjustable plate shearing machine.
Background technology
Hydraulic system is the important motivity system of plate shearing machine, and the difference of its structure is directly connected to the shear constitution of plate shearing machine, the complexity of hydraulic system, stability and system temperature thereof, directly has influence on the operation of plate shearing machine.If hydraulic system design is not good, causes cutter to shear that dynamics is not enough, system temperature is too high easily and influence work durability, the system complex degree direct influence operating characteristics of system.The oil path block volume of hydraulic system in the market is big, and weight is big, and element is many, install to be difficult for, and to need a plurality of valve groups realize that angle adjustment and knife rest shear and backhaul, like this since the cost height of hydraulic system, leakage point is many.
Summary of the invention
The purpose of the utility model provides that a kind of structural system element is few, level of integrated system is high; Production process is simple, cost is low, in the plate shearing machine shear history, can guarantee big flow, and leakage point is few; The hydraulic system heating reduces, and the adjustment angle simply is used for the hydraulic means of angle adjustable plate shearing machine.
The purpose of the utility model realizes through following technical scheme.
A kind of hydraulic means that is used for the angle adjustable plate shearing machine; It is characterized in that: said hydraulic means comprises oil pump, compressed oil cylinder, pressure logical block assembly, ball valve, master cylinder, auxilliary oil cylinder, auxiliary return facilities, knife rest and angle adjustment module; Oil pump is connected with compressed oil cylinder, angle adjustment module through pipeline; Compressed oil cylinder is connected with angle adjustment module, ball valve, pressure logical block assembly through pipeline, and ball valve is connected on the pipeline between pressure logical block assembly and the master cylinder, and auxilliary oil cylinder is connected with master cylinder, angle adjustment module through pipeline; Master cylinder, auxilliary oil cylinder are connected with knife rest, and auxiliary return facilities is connected with knife rest.
Said angle adjustment module comprises a magnetic valve, and magnetic valve is connected with auxilliary oil cylinder, oil pump, compressed oil cylinder respectively.
Said angle adjustment module comprises two magnetic valves and a check valve, and check valve is connected with two magnetic valves through pipeline, and auxilliary oil cylinder is connected with two magnetic valves through pipeline.

Description of drawings
Fig. 1 is used for the structural representation of the hydraulic means of angle adjustable plate shearing machine for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the hydraulic means that the utility model is used for the angle adjustable plate shearing machine is described in further detail.
As shown in Figure 1; The hydraulic means that the utility model is used for the angle adjustable plate shearing machine comprises oil pump 1, compressed oil cylinder 2, pressure logical block assembly 3, ball valve 4, master cylinder 5, auxilliary oil cylinder 6, auxiliary return facilities 7, knife rest 8 and angle adjustment module 9; Oil pump is connected with compressed oil cylinder, angle adjustment module through pipeline; Compressed oil cylinder is connected with angle adjustment module, ball valve, pressure logical block assembly through pipeline, and ball valve is connected on the pipeline between pressure logical block assembly and the master cylinder, and auxilliary oil cylinder is connected with master cylinder, angle adjustment module through pipeline; Master cylinder, auxilliary oil cylinder are connected with knife rest, and auxiliary return facilities is connected with knife rest.The angle adjustment module comprises a magnetic valve, and magnetic valve is connected with auxilliary oil cylinder, oil pump, compressed oil cylinder respectively.The angle adjustment module comprises two magnetic valves and a check valve, and check valve is connected with two magnetic valves through pipeline, and auxilliary oil cylinder is connected with two magnetic valves through pipeline.
The utility model is used for the ball valve of the hydraulic means of angle adjustable plate shearing machine only closes when angle diminishes, and all the other times are unlatching.During normal the shearing, the oil that oil pump is discharged is pressed into the master cylinder epicoele after pressure logical block assembly is built pressure, and master cylinder and auxilliary oil cylinder series connection DL synchronization and knife rest is accomplished shear, and shears to accomplish the auxiliary return facilities in back and support the backhaul after knife rest is accomplished shearing.When need with the knife rest angle from large to small the time; Only need close ball valve; 1YA gets; Simultaneously angle adjustment modular valve group is gone into master cylinder cavity of resorption and auxilliary oil cylinder epicoele with oil pressure, this moment auxilliary oil cylinder piston bar to drive the knife rest right-hand member because of the pressure effect is descending descending, motionless, the right reduction in knife rest left side this moment and angle is reduced.When need change from small to big the knife rest angle; Because of auxiliary return facilities is given the power upwards that is about knife rest all the time; Only need this moment the oil of master cylinder cavity of resorption and auxilliary oil cylinder epicoele to be flowed back to fuel tank automatically under the return facilities effect through angle adjustment modular valve group; Spend on knife rest right-hand member and the auxilliary oil cylinder piston bar, this moment, the knife rest left end was motionless, and knife rest the right raises and accomplishes the big action of angle change.
