Abstract
The utility model discloses a master cylinder of a swing-type shearing machine without lateral forces in the technical field of a plate shearing machine, comprising a cylinder barrel, wherein the cylinder barrel is internally provided with a piston head in a matching manner; a piston rod extends out from a guide sleeve arranged at the lower end of the cylinder barrel; the guide sleeve and the piston rod are connected in a sealing manner; the periphery of the piston rod is provided with a sealing piece to separate an upper cavity and a lower cavity of a piston in a sealing manner; the piston rod is hollow; an ejector rod extends into the piston rod upward from the lower end; a gap is left between the ejector rod and an inner cavity of the piston rod; the upper end of the ejector rod is connected with the piston head by a spherical joint bearing; and a pressure plate which is connected with a knife rest is arranged at the lower end of the ejector rod. When the master cylinder is in working, reacting force from workpieces is transferred to the cylinder barrel by the pressure plate, the ejector rod and the piston head, no lateral thrust exists between the piston rod and the guide sleeve, therefore, the sealing piece between the piston rod and the guide sleeve is easier to keep good sealing state. In the master cylinder, external leakage can be guaranteed not to occur, the working is more reliable, and the master cylinder can be applied to the swing-type plate shearing machine.
Description
Technical field
The utility model relates to a kind of hydraulic pendulum plate shears, particularly the hydraulic jack of hydraulic pendulum plate shears.
Background technique
Hydraulic pendulum plate shears of the prior art is mainly by frame, knife rest, composition such as master cylinder and worktable, master cylinder is fixed on the frame, its structure includes cylinder barrel, cooperate in the cylinder barrel and be provided with piston head, the guide sleeve that the piston rod that links to each other with piston head is provided with from the cylinder barrel lower end stretches out downwards, piston-rod lower end links to each other with pressing plate through the sphere joint shaft bearing, knife rest is connected with pressing plate, the inner cavity of cylinder that is positioned at piston head top is called piston upper chamber, inner cavity of cylinder between underside of the piston head and guide sleeve is called the piston cavity of resorption, the piston head periphery is provided with Sealing with piston upper chamber and piston cavity of resorption seal isolation, is tightly connected between guide sleeve and the piston rod.During its work, depress knife rest, make knife rest do rotation motion, by the blade cut-out metal blank of knife rest front-end face by the hydraulic coupling piston rod.In the course of the work, the reaction force that comes from workpiece passes to piston rod through pressing plate, joint shaft bearing, a part is born by hydraulic oil along the component of piston rod axial direction, another part perpendicular to piston rod to separation bear by guide sleeve, because cooperate area little between piston rod and the guide sleeve, the bearing capacity of the Sealing of piston rod and guide sleeve is poor, the Sealing at this place damages easily, cause the leakage of oil of master cylinder cavity of resorption, influence normal production work.
The model utility content
The purpose of this utility model provides a kind of no lateral force swing-type plate shears master cylinder, makes guide sleeve not bear lateral thrust, guarantees the outside seal of cylinder barrel, can not form external leakage.
The purpose of this utility model is achieved in that a kind of no lateral force swing-type plate shears master cylinder, comprise cylinder barrel, cooperate in the cylinder barrel and be provided with piston head, the guide sleeve that piston rod is provided with from the cylinder barrel lower end stretches out downwards, be tightly connected between guide sleeve and the piston rod, described piston head periphery is provided with Sealing with piston upper chamber and piston cavity of resorption seal isolation, described piston rod hollow, one push rod upwards stretches in the piston rod from the lower end, leave the gap between push rod and the piston rod cavity, link to each other through the sphere joint shaft bearing on the push rod with between the piston head, the push rod lower end is provided with the pressing plate that is connected with knife rest.
During the utility model work, the reaction force that comes from workpiece passes to piston head through pressing plate, push rod, passes to cylinder barrel through piston head again, because the diameter of piston head itself is bigger, and highly higher, and wideer Sealing can be set on piston head, its bearing capacity is strong, and is not fragile; And do not have lateral thrust between piston rod and the guide sleeve, so the good sealing state of the easier maintenance of the Sealing between piston rod and the guide sleeve; Compared with prior art, the utility model beneficial effect is that it can guarantee that master cylinder can not produce external leakage, and the possibility of its internal leakage is also very little, and its work is more reliable, and this device is mainly used on the swing-type plate shears.
For ease of lubricating of sphere joint shaft bearing, described pressing plate is provided with oil intake nozzle, and oil intake nozzle links to each other with the oil input channel of setting in the pressing plate, and the push rod center is provided with the oilhole of connecting sphere joint shaft bearing working surface, and described oilhole is connected oil input channel.Can regularly inject lubricating grease by oil intake nozzle, joint shaft bearing is lubricated, guarantee that its work is good.
For avoiding dust to enter piston rod cavity, the proper functioning generation harmful effect to the sphere joint shaft bearing is provided with dust ring between the lower end of described piston rod and the push rod.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 cylinder barrel, 2 piston heads, 3 Sealings, 4 sphere joint shaft bearings, 5 push rods, 6 piston rods, 7 guide sleeves, 8 dust rings, 9 oil intake nozzles, 10 pressing plates, 11 oil input channels, 12 oilholes.
Embodiment
