accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 arranges the structural representation of communicating pipe on cylinder body diapire.
In figure: 1 cone table, 2 sealing shrouds, 3 diapires, 11 pistons, 12 cylinder bodies, 13 soft plastic bags, 15 pin holes, 16 communicating pipes, 17 vacuum pumping pumps, 18 secondary oil pumps, 19 one-level oil pumps, 20 bypass pipes, 21 hydraulic-oil filling spaces, 22 steel bands, 23 ceramic powder material, 24 rubber stoppers.
The specific embodiment
As shown in Figure 1, a kind of cylindrical ceramic building structural member blanking device comprises that cylinder body 12 and cylinder mouth form the piston 11 of liquid sealing and piston is held in to the force application apparatus in cylinder mouth.When vacuumizing, this force application apparatus keeps piston excessively not move down, and guarantees the gap between soft plastic bag and cylinder body diapire.When servicing fluids force feed, this force application apparatus keeps piston to move on can not be excessively, assurance piston seal cylinder mouth.
Cylinder body and piston surround cylindrical cavity, inner chamber is equipped with for filling with the cylindrical shape polyurethanes soft plastic bag 13 of ceramic powder material 23, soft plastic bag upper end oral area is by rubber stopper 24 shutoff, rubber stopper is fixed on piston lower end so that soft plastic bag is suspended in inner chamber, gap between soft plastic bag and cylinder body inwall is 200MPa hydraulic-oil filling space 21, one pin hole 15 that axially runs through piston and rubber stopper is for discharging ceramic powder material gas, communicating pipe 16 is set on cylinder body diapire, by first vacuumizing communicating pipe and then servicing fluids force feed.Vacuum pumping pump 17 is connected to realize hydraulic-oil filling space and vacuumizes with communicating pipe by check valve.Hydraulic-oil filling pipe is connected to realize hydraulic-oil filling with communicating pipe, needle valve is set on hydraulic-oil filling pipe in turn, hydraulic fluid pressure is risen to the secondary oil pump 18 of 200MPa and the one-level oil pump 19 that hydraulic fluid pressure is risen to 80MPa from 80MPa, the inlet/outlet pipe of secondary oil pump also connects by bypass pipe 20, and needle valve is set on bypass pipe.
The cylindrical shape polyurethanes soft plastic bag that fills with ceramic powder material is passed through to rubber stopper shutoff, then be suspended in inner chamber, by first vacuumizing communicating pipe, then two needle valves are all in opening, primary oil pump startup, to the 80MPa hydraulic oil of annotating in hydraulic-oil filling space, after in hydraulic-oil filling space, hydraulic fluid pressure is stablized, close the needle valve of bypass pipe, open secondary oil pump simultaneously, make hydraulic fluid pressure in hydraulic-oil filling space reach 200MPa, ceramic powder material in soft plastic bag is subject to high pressure aftershaping, obtain the cylindrical ceramic building structural member blank of compactness good (or density is large).After this blank sintering, structural strength is large.If directly with the pressurization of 200MPa hydraulic oil, because pressure increasing degree is huge, cause the interior ceramic powder material each several part amount of contraction gap of soft plastic bag larger, the blank forming difference in size of acquisition, in addition, blank is also prone to crackle.Therefore first, with the pressurization of 80MPa hydraulic oil, ceramic powder material is carried out to precompressed, then with the pressurization of 200MPa hydraulic oil, ceramic powder material is carried out to final pressure.
The barrel of cylinder body comprises that inner core basic unit and helical coated are wound in four layers of steel band 22 in inner core basic unit, the coated opposite joint forming compared with internal layer steel strip winding in more outer steel band center in identical and this two-layer steel band of adjacent two layers steel strip winding direction.The bearing capacity of this sandwich construction barrel improves.
As shown in Figure 2, cylinder body diapire 3 taper hole of having got on the bus, this taper hole is built-in with cone table, cone tubular sealing shroud is set between cone table and taper hole, taper hole runs through diapire, and the large end of taper hole is compared with the more close inner chamber of small end, the cone table axle center through hole that drills and reams, be placed in communicating pipe 16 in this through hole and and this through hole interference fit, taper hole cone angle beta is 52-53 °.Taper hole, sealing shroud and cone table form hermetically-sealed construction, and owing to adopting cone match, this hermetically-sealed construction under high pressure has good sealing.This hermetically-sealed construction has guaranteed the structural strength of cylinder body diapire simultaneously.
