This concrete core slab extrusion device, comprises frame, outlet that to be the import other end be in the one end be fixed in frame extrude storehouse; The upper bulkhead extruding storehouse arranges charge door, charge door cover plate is set at charge door place; Charge door cover plate is connected with driving the charge door cover plate drive unit be arranged in frame of charge door cover plate movement; Be provided with multiple core rod extruding in storehouse, one end of core rod is connected with the one end stretching into the knife rest bar extruded in the import of storehouse, and the other end of knife rest bar is arranged in frame; Core rod, from the one end be connected with knife rest bar to the other end, reduces after the periphery of its cross section increases gradually more gradually; The push pedal that outer peripheral face and the inwall extruding storehouse import department match is slidably arranged on knife rest bar, and push pedal is connected with the push pedal thrust unit be arranged on support driving push pedal to move left and right along knife rest bar; Each mold insert structure is identical; Each core rod maximum cross section area sum is x, the each core rod one end cross-sectional area sum be connected with knife rest bar is y, each core rod other end cross-sectional area sum is z, extrude storehouse cross-sectional area w, 3.5 (w-x) >=w-y >=2.5 (w-x), w-z>w-y>w-x; Arrange feed bin extruding top, storehouse, the discharging opening of feed bin communicates with charge door; Through feed bin when charge door cover plate moves, periphery and the feed bin inwall of charge door cover plate match; Mobile trolley device comprises stir storehouse, the shaft be arranged in stir storehouse, the stirring vane arranged on shaft, the travelling carriage be connected with stir storehouse, shaft be arranged on travelling carriage, be connected for the shaft drive unit driving shaft to rotate; Travelling carriage is slidably arranged in frame, and travelling carriage is connected with the mobile truck drive unit driving mobile trolley device to move left and right relative to frame; When mobile trolley device moves to a certain position, the outlet of stir storehouse communicates with the import of feed bin; When mobile trolley device moves to another position, the outlet of stir storehouse is arranged on shutter in frame, that be positioned at feed bin side and closes; Mobile truck drive unit is oil cylinder;

Extruding storehouse is the cuboid that four blocks of plates surround, and the inwall extruding storehouse is provided with the lug boss extending to and extrude storehouse outlet, is extruding on the inwall of storehouse arrange the recess corresponding with lug boss to relative another of storehouse inwall of extruding arranging lug boss;

It also comprises wire-electrode cutting device, and wire-electrode cutting device comprises slip and arranges the cutting rack in frame, the line of cut be arranged on cutting rack; Cutting rack is positioned at extrudes storehouse export department; Cutting rack is connected from extruding the cutting rack drive unit of outlet side, storehouse to opposite side movement with drive cutting rack, line of cut.

The beneficial effect of this technology: because core rod is from the one end be connected with knife rest bar to the other end, reduces after the periphery of its cross section increases gradually more gradually; That is, core rod outer surface and the gap of extruding between the inwall of storehouse first reduce to increase gradually more gradually.We are core rod outer surface and extrude the region that gap between the inwall of storehouse first reduces gradually and be referred to as compressional zone, and core rod outer surface and the region increased gradually after extruding between the inwall of storehouse gap are referred to as to loosen district.When concrete passes through from core rod outer surface and the gap of extruding between the inwall of storehouse, first from compressional zone by time increased by compacted, density, and then through loosening district, volume of concrete after compression increases, unclamps (its internal stress may be made to be discharged), when such concrete leaves core rod, core rod place originally just defines concrete hollow part, and the concrete of hollow part periphery can not cave in, slump.If remained unchanged again after core rod outer surface and the gap of extruding between the inwall of storehouse first reduce gradually, concrete is compressed rear one and is kept this state, when leaving core rod Deng concrete, perhaps due to the releasable more greatly and not reason of concrete internal stress, the concrete of hollow part periphery will cave in, slump, and product quality is defective.Due to 3.5 (w-x) >=w-y >=2.5 (w-x), w-z>w-y>w-x, further ensure concrete compression ratio (about 2.5 to 3.5 times), simultaneously, also ensure that the concrete of hollow part periphery can not cave in, come off, improve the quality of cored slab.

While push pedal carries out concrete being carried out to compression operation, stir storehouse returns to shutter top, and concrete can be placed in stir storehouse and stir; When the compression end of job, charge door cover plate leave charge door, then drive mobile trolley device, the outlet of stir storehouse communicates with the import of feed bin, and the concrete be stirred just falls in feed bin automatically; Then mobile trolley device is driven, stir storehouse returns to shutter top, then by the movement of charge door cover plate, concrete press-in in feed bin is extruded in storehouse, carry out next step operation, enhance productivity further, simultaneously by stirring vane on shaft to concrete stirring, to also prevent in stir storehouse concrete solidifies.Feed bin facilitates concrete to add and extrudes in storehouse.Oil cylinder is as mobile truck drive unit, and structure is simple, easy to use.

Core rod is distributed on same horizontal plane, distance between adjacent two core rods is equal, the cored slab with multiple hollow part (identical with core rod quantity) be positioned in same level can be produced, namely hollow part is the quadrangle of multiple band fillet be positioned in same level, and this cored slab can carry larger power; The syndeton of this knife rest bar and core rod is simple, reliable, prevents exposing of connecting bolt, reduces the resistance of concrete movement.

Owing to extruding on the inwall of storehouse, lug boss and recess are set.Like this, the outer peripheral face of the cored slab produced is exactly and the rectangle extruded storehouse and match, meanwhile, two sides that cored slab is relative just define the fin (coincideing with the recess extruded on the inwall of storehouse) matched and groove (coincideing with the lug boss extruded on the inwall of storehouse).Like this, cored slab is when splicing, and fin can embed groove, defines tenon groove structure, convenient splicing, also improves the rear intensity of splicing.

Although, this extruder can the cored slab of production random length, but may the terminal surface of cored slab may out-of-flatness, in order to terminal surface smooth of cored slab, simultaneously also in order to the more accurate cored slab of length can be produced, this cored slab of wire-electrode cutting device can be used to cut off.Line of cut moves to opposite side from the side of cored slab and just cored slab is cut off under the drive of cutting rack, and two end faces of the cored slab that cut line cuts off are just very smooth.Adopt line of cut to cut, other will be caused to damage to cored slab, cut surface is smooth.Preferably, cutting rack drive unit is oil cylinder.

During use, the process of this extruder production concrete core slab is as follows.The concrete be stirred is added from charge door and extrudes storehouse, use charge door cover plate to build charge door; Driving push pedal is moved, and concrete being promoted from extruding outlet side, storehouse import one lateral extrusion storehouse, concrete is passed through from core rod and the gap of extruding between the inwall of storehouse, but push pedal can not move to the periphery maximum of core rod; Driving push pedal oppositely movement is repositioned to the sidepiece below charge door; Meanwhile, charge door cover plate is removed from charge door.Repetition said process.Why push pedal can not move to the periphery maximum of core rod, to ensure that the part by compressing in rear concrete also stays compressional zone, like this, push pedal promotes the concrete added from charge door next time, after the concrete that adds when being compressed by compressional zone, reliable contacts just and between the previous concrete staying in compressional zone, the pressure between them is just very large, previous concrete can and after merge completely between the concrete that adds and can not gap be had.Like this, use this extruder, the concrete core slab of endless can be produced completely.

Therefore, the hollow part of the concrete core slab using this extruder to produce can not cave in, slump.Concrete is through overcompression, and density is comparatively large, and obtained concrete core slab intensity is high.Can continuous seepage, production efficiency is high.The concrete core slab of random length can be produced.

Above-mentioned concrete core slab extrusion device, push pedal thrust unit is oil cylinder.Adopt oil cylinder pushing push pedal, compared to the push pedal thrust unit (as motor) of other type, thrust is large, and large to concrete pressure, power is little.

Above-mentioned concrete core slab extrusion device, charge door cover plate drive unit is oil cylinder.

Above-mentioned concrete core slab extrusion device, core rod is from the one end be connected with knife rest bar to the other end, and the periphery of its cross section first increases gradually, then remains unchanged, and then reduces gradually.We are core rod outer surface and extrude the region that the gap between the inwall of storehouse remains unchanged and be referred to as pressurize district, when concrete passes through from core rod outer surface and the gap of extruding between the inwall of storehouse, first from compressional zone by time increased by compacted, density, keep volume, density constant again through pressurize district, and then through loosening district, volume of concrete after compression increases, unclamps (its internal stress may be made to be discharged), like this, the change of concrete internal stress is more mild, prevent hollow part periphery further concretely to cave in, slump.

This technology provides one simultaneously can continuous seepage, production efficiency is high, can produce the concrete core slab continuous producing method of the concrete core slab of random length, and the concrete core slab density that the method is produced is larger, intensity is high, and hollow part can not cave in, slump.

This concrete core slab continuous producing method, use above-mentioned concrete core slab extrusion device, it comprises the steps:

A, the concrete be stirred added from charge door and extrudes storehouse, use charge door cover plate to build charge door;

B, driving push pedal are moved, and concrete being promoted from extruding outlet side, storehouse import one lateral extrusion storehouse, concrete is passed through from core rod and the gap of extruding between the inwall of storehouse, but push pedal can not move to the periphery maximum of core rod;

C, driving push pedal oppositely movement are repositioned to the sidepiece below charge door; Meanwhile, charge door cover plate is removed from charge door.

D, repeat above-mentioned steps a, b, c; Shaping concrete core slab just constantly exports out from extruding storehouse.

Preferably, it also comprises the steps: when shaping concrete core slab reaches the length of needs, by cutter sweep, the cored slab extruded is cut off.
