Description
Technical field
The present invention relates to hydraulic cylinder technical field, more particularly to a kind of plate shearing machine hydraulic cylinder based on spring.
Background technology
Plate shearing machine is to be done reciprocating linear motion to shear the machine of plate with relatively another blade of a blade, is borrowed in movement
Cutter and fixed bottom knife, using rational gap blade, shearing force is applied to the sheet metal of various thickness, makes plate
Material presses required size fracture separation.Plate shearing machine belongs to one kind in metal forming machinery, acts predominantly on metal-working industry.
Hydraulic cylinder is used to compress plate in plate shearing machine, to prevent plate from being moved in shearing.Existing fluid pressure type plate shearing machine
In use, after braking, hydraulic cylinder it is waiting for a long time, stroke is longer, longer on the production time, and production efficiency is not
It is high.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of plate shearing machine hydraulic cylinder based on spring.
The technical solution adopted in the present invention is：A kind of plate shearing machine hydraulic cylinder based on spring, it is characterised in that：Including
Cylinder barrel, piston, piston rod, end cap and seal, the piston is fixedly installed in piston rod one end, and piston is arranged on cylinder barrel
It is interior, move up and down relative to inner wall of cylinder, be equipped with a hollow out among the end cap, the cylinder barrel other end is additionally provided with to fixation
The end cap of piston rod, and the movement of end cap limitation piston, seal is additionally provided between the end cap and piston rod, described
Piston base is also movably installed with elastomeric element, and the elastomeric element is subject to the pressure of piston and cylinder base, and rebounds to work
Stopper rod is to brake.
Further, the elastomeric element is spring.
Further, it is 2-3cm when the spring is not affected by pressure, is 0.3-0.5cm when being under pressure.
Further, the piston base is additionally provided with connecting component.
Further, it is connected through a screw thread between the connecting component and spring.
Compared with prior art, the beneficial effects of the invention are as follows：Spring in the present invention to piston provide one it is upward
Elastic force, piston can fast braking, reduce the stroke of hydraulic cylinder, improve work efficiency, add yield.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the plate shearing machine hydraulic cylinder based on spring.
Wherein：1- cylinder barrels, 2- pistons, 3- piston rods, 4- end caps, 5- seals, 6- elastomeric elements, 21- connecting components,

Embodiment
In order to deepen the understanding of the present invention, the present invention is further described with reference to the accompanying drawings and examples, the implementation
Example is only used for explaining the present invention, and protection scope of the present invention is not formed and is limited.
As shown in Figure 1, a kind of plate shearing machine hydraulic cylinder based on spring, including cylinder barrel 1, piston 2, piston rod 3, end cap 4
With seal 5, piston 2 is fixedly installed in 3 one end of piston rod, and piston 2 is arranged in cylinder barrel 1, above and below 1 inner wall of cylinder barrel
Movement, the centre of end cap 4 are equipped with a hollow out 41, and 1 other end of cylinder barrel is additionally provided with the end cap 4 to fixed piston rod 3, and end cap 4
The movement of piston 2 is limited, seal 5 is additionally provided between end cap 4 and piston rod 3, piston base is also movably installed with elastomeric element
6, elastomeric element 6 is subject to the pressure of 1 base of piston 2 and cylinder barrel, and rebounds to piston rod 3 to brake.
In the above-described embodiments, when plate shearing machine left end hydraulic cylinder epicoele oil inlet, piston 2 declines, and extrudes spring 61, and same
When its cavity of resorption oil enter right end hydraulic cylinder epicoele decline piston 2, extrude spring 61, so as to ensure that the parallel shifting of knife rest
Work(；Spring 61 provides a upward elastic force to piston 2, piston 2 can fast braking, shear plate hydraulic cylinder upsprings, and shortens knife
The path increment of frame, can also improve the number of strokes per minute, so as to improve the productivity of machine.
In the above-described embodiments, it is connected through a screw thread between connecting component 21 and spring 61, is convenient for changing spring 61, is improved
The service life of hydraulic cylinder.
What the embodiment of the present invention was announced is preferred embodiment, but is not limited thereto, the ordinary skill people of this area
Member, easily according to above-described embodiment, understands the spirit of the present invention, and makees plate shearing machine and go out different amplification and change, but as long as not
Depart from the spirit of the present invention, all within the scope of the present invention.
