Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, be coaxial Press cylinder device one embodiment's of the utility model single pole two-cylinder type structural representation one, comprise outer cylinder pressure 1 and the interior cylinder pressure 2 of inside and outside double-cylinder coaxial formula design.
Wherein, in outer cylinder pressure 1, establish an axially displaceable interior cylinder pressure 2 that is the piston rod shape, as shown in Figure 1, should outer cylinder pressure 1 bottom establish one and run through attachment hole 11 and external control valve 111 (the 3 stops control valve that tool enters, ends, goes out), establish one in outer cylinder pressure 1 the other end and run through attachment hole 12 and external control valve 121 (the 3 stops control valve that tool enters, ends, goes out).
But an end of being located at the interior cylinder pressure 2 of axial stretching displacement in the outer cylinder pressure 1 stretches out outer cylinder pressure 1 front end, and the piston body 20 that the bottom of cylinder pressure 2 is integrated in being somebody's turn to do, these piston body 20 external diameters are greater than interior cylinder pressure 2 external diameters, the design that this piston body 20 and interior cylinder pressure 2 bottoms are integrated so that the interior cylinder pressure 2 that this bottom has a piston body 20 in outer cylinder pressure 1 just as the piston rod of force-applied axial reciprocating displacement.In addition, interior cylinder pressure 2 bottom piston bodies 20 are provided with and run through through hole 21, and this runs through through hole 21 apertures and outer cylinder pressure 1 bottom, and to run through attachment hole 11 apertures identical, and should communicate with interior cylinder pressure 2 inside by interior cylinder pressure 2 bottom piston bodies 20 set through holes 21 that run through.Be provided with a piston rod 3 in interior cylinder pressure 2 inside, interior cylinder pressure 2 the other ends are established one and are run through attachment hole 22 and external control valve 221 (the 3 stops control valve that tool enters, ends, goes out).
As shown in fig. 1, but in this piston rod 3 axial reciprocating telescopic displacements of cylinder pressure 2 in interior cylinder pressure 2, with start one extruding force of setup pressure value forward; But and interior cylinder pressure 2 also the axial reciprocating telescopic displacement in outer cylinder pressure 1, by interior cylinder pressure 2 piston bodies 20 lifting surface areas greater than piston rod 3 lifting surface areas in the interior cylinder pressure 2, generation reaches generation greater than the forward extruding force output of setup pressure value of interior cylinder pressure 2 piston rods 3 greater than the extruding force of piston rod 3 axial advancement displacements so that the axial advancement velocity of displacement of interior cylinder pressure 2 is slightly slow.
It uses action as shown in FIG.:
As shown in Figure 1, the external control valve 111 that runs through attachment hole 11 when outer cylinder pressure 1 is controlled when entering formula, introduce pressure source and enter outer cylinder pressure 1 inside, formula till the external control valve 121 that this moment, outer cylinder pressure 1 the other end ran through attachment hole 12 is controlled, the external control valve 221 that interior cylinder pressure 2 the other ends run through attachment hole 22 is controlled as going out formula, therefore pressure source is run through in the interior cylinder pressure 2 that through hole 21 enters by the bottom piston body 20 of interior cylinder pressure 2, produces extrapolation piston rod 3 displacements and outwards protracts and push to the location.The external control valve 221 that runs through attachment hole 22 when interior cylinder pressure 2 the other ends is controlled when entering formula, and outer cylinder pressure 1 runs through the external control valve 111 of attachment hole 11 and controls when going out formula, cylinder pressure 2 piston rods 3 location of inwardly retracting in then producing.
As shown in Figure 2, through interior cylinder pressure 2 piston rods 3 after start is pushed forward repeatedly, because being extruded gradually compacting of thing, so when interior cylinder pressure 2 piston rods, 3 displacements and protruding arrival is located suffered resistance and reached one when setting numerical value, the external control valve 121 that this outer cylinder pressure 1 the other end runs through attachment hole 12 is controlled as going out formula, the piston body 20 that then impels interior cylinder pressure 2 displacement of advancing in the cylinder pressure 1 outside, and make whole interior cylinder pressure 2 (together with piston rod 3) push ahead extruding.
Because the pressure source that this moment, outer cylinder pressure 1 ran through attachment hole 11 introducings enters outer cylinder pressure 1 inside, and interior cylinder pressure 2 piston bodies 20 lifting surface areas that pushed away are definitely greater than the lifting surface area of interior cylinder pressure 2 piston rods 3, therefore produced the output of pushing pressure greater than before the previous piston rod 3 so that push away the interior cylinder pressure 2 that advances, reach the suffered resistance in interior cylinder pressure 2 piston rods, 3 overhanging location and reach one when setting numerical value, push pressure by before the appending of interior cylinder pressure 2, and make be extruded thing certain reach consolidation effect.
As shown in Figure 3, before the piston rod 3 of finishing interior cylinder pressure 2 and interior cylinder pressure 2 itself, push and press to the location of protracting, till external control valve 111 that outer cylinder pressure 1 runs through attachment hole 11 is controlled during formula, formula till the external control valve 121 that formula and outer cylinder pressure 1 the other end ran through attachment hole 12 till the external control valve 221 that interior cylinder pressure 2 the other ends run through attachment hole 22 was controlled is controlled is in order to being extruded the packing binding of thing under the compacting situation.Thereafter, the external control valve 111 that outer cylinder pressure 1 runs through attachment hole 11 is controlled as going out formula, the external control valve 221 that interior cylinder pressure 2 the other ends run through attachment hole 22 is controlled as entering formula, and the external control valve 121 that outer cylinder pressure 1 the other end runs through attachment hole 12 is controlled as entering formula, reach interior cylinder pressure 2 piston rods 3 and interior cylinder pressure 2 retreating rapidly simultaneously to the location of retracting own, supply the initial of next do action.
Therefore, the coaxial Press cylinder device of the utility model single pole two-cylinder type can reach same input start source force value really on actual utilization benefit, and the cylinder pressure that can effectively produce pressurization output uses effect, and then promotes industry applications and the economic benefit of cylinder pressure.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
