Valve 243 is pressed into jack ontology 241, when pressure gauge 246 is more than 0, is changed to control second pressure bar 2444 and is continued to very heavy
It pushes up press-in hydraulic oil in ontology 241 and then applies pressure, 241 internal pressure of jack ontology causes inner sleeve 2412 to ramp up
It rises, it is ensured that its static load, slowly ton gradual application pressure from zero to tens, and according to the pressure of the control pressure of pressure gauge 246
Value.In the process, except the remaining part that compression bar 34 remains stationary as mold 30 is slowly moved up with inner sleeve 2412, compression bar 34
Dusty material therebetween is compacted in flakes with pressure head 36.
Release step:After tabletting, by the rotation counterclockwise of the release control wheel 284 of pressure relief device 28 to control overflow
Valve 282 is opened, and hydraulic oil flows back to oil conservator 262, the inner sleeve of jack ontology 261 through overflow valve 282 in jack ontology 261
Cylinder 2612 drops to bottom, and pressure gauge 266 returns back to 0, then unscrews bolt 268, and mold 30 is taken from mold placement platform 261
Under, by the clockwise rotation of release control wheel 284 overflow valve 282 to be controlled to close, release finishes.
Demoulding step:Referring to shown in Fig. 1,4, the mold 30 removed is inverted, removes bearing 38, groove body 392 is downward
Ejection seat 39 is positioned on die body 32, and the lower face of ejection seat 39 is resisted against the upper surface of die body 32, and mold 30 is positioned over mould
Have in mounting hole 262, bolt 268 is screwed and is contacted in ejection seat 39, then shake operation handle 245 so that manipulator
The first pressure bar 2442 or second pressure bar 2444 of 245 control pressure bar portion 244 of handle press to jack ontology 241 and are caused
Inner sleeve 2412 is raised above, and ejection seat 39 and die body 32 remain stationary as, and compression bar 34 is moved up with inner sleeve 2412, and compression bar 34 pushes away
Dynamic head 36 and the tabletting suppressed move up and are detached from die body 32, repeat release step, complete demoulding.
As described above, the advantageous effect that the technical solution of the embodiment of the present invention is brought is:The present invention's carries under handle
Laminated structure 100, due to including pressure applicator 20 so that the pressing structure 100 with handle slowly can press and reach under static load
