Described internal mold 1, steel cylinder 2 are arranged on bed die 4, and top arranges backform 5.
Described backform 5 is arranged blanking and bore 6, blanking is bored 6 tops and is arranged the hopper 7 with its correspondence, and described blanking cone 6 and hopper 7 correspondence make material flow in the cavity of formation between internal mold 1 and steel cylinder 2.
Be provided with back taper 71 in described hopper 7, can relatively move up and down between described hopper 7 and back taper 71.
Described internal mold door-plate 11 drives linkage 9 to realize closure or openness by gear train 8.
Described guide rail 31 is driven by feed screw nut 10 and moves up and down.
Vibrator 13 is established in described internal mold 1.
Below in conjunction with accompanying drawing, specific description is made to the present invention, better to understand the present invention:
Small dimension PCCP vibrates punching block primarily of bed die 4, internal mold 1, external mold (PCCPE has external mold, and PCCPL is without external mold), backform 5, blanking cone composition.
1) bed die 4 main body is formed by cast steel fine finishining, is equipped with other annex.
Bed die 4 is mainly in order to locate one or two (PCCPE) volume of internal mold 1, steel cylinder 2, external mold (only having PCCPE to have) formation opening upwards; Only limit the mechanism that internal mold 1 axially moves.
2) internal mold 1 main body becomes single radial cut flexible steel mould by special plate assembly welding, and be accompanied by vibrator 13.
Internal mold 1 is under the door state of pass, and with bed die 4, steel cylinder 2 forms the volume of opening upwards, and is accompanied by vibrator 13, is convenient to concrete formation; Internal mold 1 is under door opening state, and internal mold internal hilar plate 11 mixes in external door panel, overall circumference is shortened, also reduces with regard to internal mold.Bed die 4, goods and internal mold 1 forms gap, is convenient to goods and takes out from internal mold 1.
3) external mold (only having PCCPE to have) main body becomes single radial cut flexible steel mould by steel plate installed-welded, and be accompanied by vibrator 13:
External mold, under the door state of pass, forms the volume of opening upwards with bed die 4, steel cylinder 2, and is accompanied by vibrator 13, be convenient to concrete formation; External mold is under door opening state, and separately, overall circumference is lengthened, and bed die 4, goods and external mold form gap to two door-plates, are convenient to external mold and take out from goods.
4) backform is mainly for locating upper end, and back taper 71 is mainly convenient to blanking.
3, technical characterstic:
1) internal mold 1 special plate has good welding performance, good toughness, and intensity is general; Special moulding process; Be convenient to open the door.Open the door, close the door, two ends transmission, upper end operate, concrete grammar is: through stage-geared, drive door plate hinge mechanism 9 open the door or close the door.Compress, unclamp by gear drive, rotary screw rod nut 10 makes it drive guide rail 31 moving linearly, and the voussoir on guide rail 31 32 groups compresses or unclamps door-plate.
2) enabling terminal mechanism is linkage 9, though be flexible steel mould, because diameter is little, length is long, and rigidity is bigger than normal, when internal mold internal hilar plate 11 mixes internal mold external door panel 12, internal mold external door panel 12 is extruded, and makes local diameter become large, demoulding difficulty; For head it off, add arc plate 121 internal mold external door panel 12 sections, strengthen its intensity, make internal mold external door panel 12 that internal mold internal hilar plate 11 is pressed to inside, when internal mold internal hilar plate 11 mixes internal mold external door panel 12, girth shortens, diameter diminishes, and makes goods and internal mold 1 occur gap, is convenient to the demoulding.
3) convenient in order to produce, also in order to not damage goods upper end during the demoulding, just internal mold internal hilar plate 11, internal mold exterior sheathing 12 being opened, instead of internal mold 1 is deviate from from goods, directly with special tube core suspender, goods being hung away; Sling together by internal mold 1 when preventing from hanging goods, internal mold 1 must do axial restriction by bed die 4 relatively.
4) because goods are little, wall is thin, prevents concrete from splashing outside, and the rib of blanking cone 6 makes inverted cone-shaped structure, and for accelerating blanking velocity, backform 5 baffle plate also makes back taper.
After adopting above technical scheme: the present invention:
1) production efficiency is high: for DN800X6 rice PCCPL pipe, every root goods only need more than ten minute, and centrifuging process is done two-tube, a hours;
2) mechanization degree is high, and operation labour intensity is low: carry out feeding by operation driving or charge car, and centrifuging process is generally hand fed;
3) energy consumption is low: vibratory process concrete compaction only needs a little pneumatic vibrator works more than ten minute, and centrifuging process is done two-tube, the work one of kilowatt motor more than 100 hours;
4) production process environmental protection: without useless slurry, sewage;
5) security is good: mould geo-stationary during vibration moulding, and without dangerous, centrifuging process mold high speed rotates, and flies mould situation and occurs, and makes drill rod and easily slip out of the hand and hurt sb.'s feelings during plasma discharge, and during hand fed, hand easily encounters the punching block of High Rotation Speed and injured;
6) versatility is good, and centrifuging process can only produce PCCPL pipe, and vibratory process both can produce PCCPL pipe, also can produce the nonstandard pipe of PCCPE type.
Good product quality: concrete density is high, impervious good, inner wall smooth.
