The specific embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. to describe the novel hydraulic machine that tensile force of the present utility model and pressure-pad-force change mutually in detail as follows:
As shown in Figure 1, the novel hydraulic machine that tensile force of the present utility model and pressure-pad-force are changed mutually, it is the hydraulic press of four rod structures, include four columns 4 and pass through entablature 3 and the sill (not shown) of nut 2 fixing and lockings on four columns 4, be provided with the stretching slide block 5 and the blankholder slide 7 that can move up and down along column 4 between entablature 3 and sill from top to bottom, being used on described stretching slide block 5 and the blankholder slide 7 runs through and is provided with the wear-resisting compound guide bushing 8 that be convenient to stretch slide block 5 and blankholder slide 7 move up and down along column 4 in the through hole of column 4.Wherein, what connect on the described entablature 3 is provided with a plurality of master cylinders 1, and described in the present embodiment master cylinder 1 is provided with 3, and the total nominal pressure of 3 cylinders is 6000T.The rod end surface of a plurality of master cylinders 1 is fixedlyed connected with stretching slide block 5.Also be provided with stretching slide block kicker cylinder 9 on the described entablature 3, described stretching slide block kicker cylinder 9 is a piston cylinder operator, the fixedly connected stretching slide block 5 of the rod end surface of stretching slide block kicker cylinder 9, the power round-trip that using liquid produces on ring surface during backhaul, when stretching slide block 5 was descending, kicker cylinder 9 did not act on.Be provided with a plurality of flanging cylinders 6 in the described stretching slide block 5, described in the present embodiment flanging cylinder 6 is provided with 8, and it is plunger case that 6 flanging cylinders are wherein arranged, and 2 flanging cylinders are piston cylinder, and 2 piston cylinders play the backhaul effect of blankholder slide simultaneously.When blankholder slide was descending, 8 flanging cylinders 6 acted on simultaneously, and the rod end surface of a plurality of flanging cylinders 6 is fixedlyed connected with blankholder slide 7.The lower plane of described stretching slide block 5 can be connected with the mould that is pressed workpiece, and the lower plane of described blankholder slide 7 can be connected with the mould that is pressed workpiece.
The novel hydraulic machine that tensile force of the present utility model and pressure-pad-force are changed mutually adopts the flanging cylinder to be installed in the two moving frame mode that draws on the slide block of Shen, and pressure-pad-force and tensile force can be transformed mutually.Pressure-pad-force is adjustable, if Q1, maximum 3000T, then tensile force just equals nominal pressure 6000T and deducts pressure-pad-force Q1, minimum 3000T, maximum 6000T.The utility model has maximally utilised nominal pressure, the corresponding energy loss that reduced.
