Chinese patent ZL 201320095679.8 discloses a kind of oval fore-set hydraulic press, what this hydraulic press solved is that hydraulic press fore-set can not keep the directed problem used, and the base of this hydraulic press needs to put on level ground, use can not be put by any direction as required, the extension elongation of fore-set is more limited, and the speed of stretching out is also slower.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of novel quick bi-directional expansion hydraulic press, the multistage fore-set of this New depressor by being symmetrical set, in hydraulic actuating cylinder oil pressure effect under shoot out, profile is light and handy, the outreach solving fore-set is limited, stretches out slow-paced problem.
The utility model is achieved by the following technical programs:
A kind of novel quick bi-directional expansion hydraulic press, comprise knob, connecting rod, cylinder body and piston, the left and right sides of described cylinder body is sealed and installed with a fore-set that can linearly move back and forth at least respectively, described fore-set is symmetrical relative to the central axis of cylinder body, the sealed bottom of described cylinder body, the top seal of described cylinder body is provided with piston, the upside of described piston is fixedly installed connecting rod, the upper end of described connecting rod is fixedly connected with knob, negative thread is provided with inside the upper end of described cylinder body, the upper end of described connecting rod is provided with the outside thread matched with the negative thread of cylinder body.
Further, the bottom inside of described cylinder body is provided with lower limit post, and the downside of described piston is fixedly installed the upper limit post corresponding with lower limit post.
Further, described knob is provided with anti-skid structure.
Further, described fore-set comprises the one-level fore-set and secondary fore-set that can linearly move back and forth, and described one-level fore-set telescopically is seal-installed on the both sides of cylinder body, and described secondary fore-set telescopically is seal-installed on one-level fore-set.
Further, described secondary fore-set is the elongated tubular construction that outer end is closed.
The beneficial effects of the utility model are: the extension elongation of the symmetrical fore-set of this New depressor is longer, be applicable to being used in the part supporting various width, and its speed stretched out, in use can not only raise the efficiency, and energy consumption is lower, structure is simple, and quality is light, convenient installation or removal, the scope be suitable for is wider.

Detailed description of the invention
Be described in further detail utility model object of the present utility model below in conjunction with the drawings and specific embodiments, embodiment can not repeat one by one at this, but therefore embodiment of the present utility model is not defined in following examples.
As shown in Figure 1, a kind of novel quick bi-directional expansion hydraulic press, comprise knob 1, connecting rod 2, cylinder body 3 and piston 9, the left and right sides of described cylinder body 3 is sealed and installed with a fore-set that can linearly move back and forth at least respectively, described fore-set is symmetrical relative to the central axis of cylinder body 3, the sealed bottom of described cylinder body 3, the top seal of described cylinder body 3 is provided with piston 9, the upside of described piston 9 is fixedly installed connecting rod 2, the upper end of described connecting rod 2 is fixedly connected with knob 1, negative thread is provided with inside the upper end of described cylinder body 3, the upper end of described connecting rod 2 is provided with the outside thread matched with the negative thread of cylinder body 3, helicitic texture is adopted to make trim step in use more accurate.
The bottom inside of described cylinder body 3 is provided with lower limit post 7, and the downside of described piston 9 is fixedly installed the upper limit post 8 corresponding with lower limit post 7.Corresponding limited post setting up and down in the process of tightening downwards, occurs the phenomenon of overvoltage in order to prevent in cylinder body 3, prevents from damaging all parts.
Described knob 1 is provided with anti-skid structure, more convenient to use, particularly when later stage fine setting, need manually slowly to adjust.
Described fore-set comprises the one-level fore-set 5 and secondary fore-set 6 that can linearly move back and forth, and described one-level fore-set 5 telescopically is seal-installed on the both sides of cylinder body 3, and described secondary fore-set 6 telescopically is seal-installed on one-level fore-set 5.Adopt multistage fore-set to make fore-set at different levels all protruding under the left and right of oil pressure, the time of stretching out of fore-set entirety is shortened greatly, and the length of stretching out is longer.
The elongated tubular construction that described secondary fore-set 6 is closed for outer end, the oil mass of the overhanging needs of fore-set of elongated tubular product is less, makes just can stretch out longer distance when the amount of exercise of piston is less, raises the efficiency.
As shown in Figure 2 be under hydraulic press initial condition, the position residing for fore-set.In use procedure, downwards pressing knob 1, makes piston 9 sharp downward movement under the effect of hydraulic oil 4, symmetrical one-level fore-set 5 and secondary fore-set 6 overhanging fast; After the externally threaded lower end of connecting rod 2 touches the negative thread of cylinder body 3 upper end, by rotating knob 1, piston 9 is slowly moved downward, symmetrical one-level fore-set 5 and secondary fore-set 6 continue overhanging, after symmetrical secondary fore-set 6 all withstands the parts needing to support, slightly rotate knob 1, between the parts that secondary fore-set 6 and needs are supported, produce certain squeese pressure, ensure the reliability supported, ensure crudy.
Machine, and confirm size qualification and after can not deforming again, contrarotation knob 1, the oil pressure of cylinder body 3 reduces, and symmetrical one-level fore-set 5 and secondary fore-set 6 can automatic retracteds, also can manually help it to bounce back.Hydraulic press can be taken off easily, and can not work piece be damaged.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
