Abstract

The invention discloses a double-action thick plate stretching hydraulic machine which adopts a four-post structure. The hydraulic machine comprises four upright posts, an upper cross beam and a lower cross beam. The upper cross beam and the lower cross beam are fixed and locked on the four upright posts by nuts, stretching sliding blocks and edge-pressing sliding blocks which can move up and down along the upright posts are arranged between the upper cross beam and the lower cross beam from top to bottom, a plurality of main cylinders are arranged on the upper cross beam in a run-through manner, the rod end faces of the main cylinders are fixedly connected with the stretching sliding blocks, a plurality of edge-pressing cylinders are arranged in the stretching sliding blocks, the rod end faces of the edge-pressing cylinders are fixedly connected with the edge-pressing sliding block, the lower planes of the stretching sliding blocks are connected with a mould of a pressed workpiece, and the lower planes of the edge-pressing sliding blocks are also connected with the mould of the pressed workpiece. A stretching cylinder is installed on the upper cross beam, and edge-pressing cylinders are installed on the stretching sliding blocks; as the edge-pressing force is part of the stretching force, the stretching force decreases when the edge-pressing force increases and correspondingly increases when the edge-pressing force decreases; the mutual conversion between the stretching force and the edge-pressing force effectively utilizes total energy of the hydraulic machine and increases the energy utilization rate.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. to describe double-action thick plate stretching hydraulic machine of the present invention in detail as follows:
As shown in Figure 1, double-action thick plate stretching hydraulic machine of the present invention, 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.
Double-action thick plate stretching hydraulic machine of the present invention 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 present invention has maximally utilised nominal pressure, the corresponding energy loss that reduced.
The course of work of double-action thick plate stretching hydraulic machine of the present invention is: when the power source of hydraulic press when master cylinder and flanging cylinder provide pressure oil, under pressure, the flanging cylinder at first drives blankholder slide and moves downward and finish flanging compacting, master cylinder drive stretching slide block moves downward then, drives the stretching slide block and finishes the action that stretches.When compacting is finished when needing backhaul, kicker cylinder drives the stretching slide block and moves upward, the blankholder slide of the piston cylinder of blankholder slide drive simultaneously moves upward, finish the backhaul action of stretching slide block and blankholder slide. an actuation cycle is finished. and when pressure-pad-force changed, tensile force also changed thereupon at work.
