Description
Technical field
The utility model relates to the composite building material and makes the field, is specifically related to a kind of make-up machine that is used to prepare composite water permeable brick.
Background technology
The dank material of uses such as permeable brick in the market, porous pavement is mainly pottery or concrete, and ceramic water-permeable brick will adopt a large amount of ore deposit soil resources, so the exploitation of raw material has caused environment damage.The permeable brick complex manufacturing of ceramic mould, and the ceramic base brick need expend a large amount of energy when forming and sintering, the cost height, production efficiency is low, and environmental protection has high input, and the one-time investment scale is big.Though the concrete permeable brick cost is low, (general particles of aggregates particle diameter is that 3mm～6mm), the macrovoid of abutment surface is permeable, and voidage is more than 20% but the particle on the permeable brick of available coagulation soil surface is thick, blocked by dust easily, therefore can not continue the water permeability that keeps high; And because the space is bigger, it is also relatively poor that it is used for the water filtration effect; The color of concrete permeable brick is single simultaneously, rough surface, and not attractive in appearance, intensity is low, destroys easily.For overcoming above-mentioned shortcoming, now researched and developed the permeable brick of macromolecular material, but, be difficult to large-scale promotion because costs of material such as resin are higher.
For overcoming the defective that the permeable brick of concrete permeable brick and macromolecular material exists, CN1966861A discloses a kind of composite water permeable brick, and described permeable brick comprises permeable top layer and porous base course, and permeable top layer and porous base course are closely as one; Include aggregate in permeable top layer and the porous base course respectively and aggregate is played the binding agent of the coating aggregate of cementation.This permeable brick has that energy savings, cost are low, better tolerance, long-term permeability rate height, advantage that intensity is high.Can be when this composite water permeable brick is made with permeable top layer and the once-combined moulding of porous base course, also can produce permeable top layer and porous base course earlier respectively, then both are combined with each other, as passing through bonding, also can produce one of permeable top layer and porous base course earlier, then another layer of moulding thereon.If again both are combined with each other after producing permeable top layer and porous base course respectively, then need two sleeve forming machine co-operation in these three kinds of methods, the operation more complicated, and also because the caking ability on permeable top layer is big and cloth is thinner, independent preparation is difficulty relatively; If produce earlier permeable top layer and porous base course again and again thereon by another layer of molding bonded, then owing to used binding agent that cost is raise, binding agent also may influence the water penetration of this fragment of brick simultaneously.Therefore be the simple and the most economical and the most practical method of producing this permeable brick with permeable top layer and the once-combined moulding of porous base course.Employing is during with the method for permeable top layer and the once-combined moulding of porous base course, and its permeable top layer material and porous base course material need add the brickmaking mould respectively, pass through the molding device compression molding again.Influenced by material cost, preparation is during composite water permeable brick, and the thickness on the permeable top layer of permeable brick is generally much smaller than the thickness of porous base course.
In composite water permeable brick is produced, can cooperate a plurality of pressure heads by using multi-cavity mold, one-step mould can be produced the polylith adobe, and the block dimensions of mold pressing is unified, conveniently deposits and practicality.But in actual production, occur because the feeding quantity error causes the cloth inequality in each die cavity through regular meeting, the adobe of this kind situation compression molding next time is difficult to guarantee that size and packing all meet established standards, and there is drawback in use in the fragment of brick that causes producing.
CN201333740Y discloses a kind of permeable brick forming machine, and the molding device of this make-up machine comprises ram drive mechanism that a plurality of pressure heads, drive ram move and the moulding box that matches with pressure head.The mould of this molding device is fixed on the vibrating device, moves between loading station and green brick forming station by cloth hopper conveyer driving lining cloth case and bed material cloth hopper and realizes twice cloth of precoat and initial bed.A plurality of pressure heads of this make-up machine are fixedly connected on side by side and realize common lifting under the drive unit, suppress the permeable block thickness unanimity of coming out like this.Yet in actual production process phenomenons such as reinforced inequality, feeding quantity error can appear, if this moment is the still consistent permeable brick packing difference of being suppressed of will certainly occurring of each pressure head depression degree, though permeable brick thickness and other permeable bricks that the less slightly mould of feeding quantity is produced are as good as, compaction rate and compression strength are less than other permeable brick and established standardses certainly.Because in actual applications, the importance of the resistance intensity of construction material is far longer than the requirement to the block thickness homogeneity, and there is very big shortcoming in the molding device of this patent disclosure on the one hand at this.
CN2182042Y discloses a kind of building-block make-up machine, this make-up machine comprises cope, drag and is installed on hydraulic jack on the frame, respectively be provided with 2-5 hydraulic jack at cope and drag place, be provided with bascule on cope and the drag.This bascule is by being installed on axle on the support, being enclosed within the connecting rod one on the axle and forming with the hinged connecting rod two of moulding box.The course of work of this make-up machine is: blank is loaded in the drag, by vibrator jolt ramming.Cope hydraulic oil cylinder driving cope descends, and to the blank pressurization, pressure reaches 20 tons.Cope be depressed into spacing after, the core casing presses down, and core body is inserted in the blank, increases squeezing effect and hollow rate..After the extrusion modling, drag oil cylinder, core body oil cylinder rise, and the cope oil cylinder is motionless, the demoulding, and drag oil cylinder, core body oil cylinder, cope oil cylinder rise to upper change point simultaneously after the demoulding.Last drag falls, and finishes a circulation.Though this building-block make-up machine is provided with cope and drag, but its blank is to be laid in the drag, cope is equivalent to pressure head, under the effect of patrix fuel tank, be used for the compacting blank, therefore the mould of this make-up machine use still is an integrated mould, and it can't solve permeable top layer equally greatly can't be in the smooth problem of mould bottom cloth because of viscosity.The bascule of this make-up machine can guarantee that moulding box keeps balance and stability when cope descends, the brick shapes that suppresses, size and specification homogeneous, but the effect of a plurality of hydraulic jacks that this make-up machine is provided with at each moulding box place only is to realize pressure superposition by a plurality of hydraulic jacks, strengthened the pressure that cope presses down, can suppress tight, high-quality fragment of brick, still can't solve the problem that the packing that causes because of reinforced uneven, feeding quantity error that can occur does not in process of production meet established standards, have bigger shortcoming.
In addition, the described make-up machine of above-mentioned two patents is not provided with at the location of mould on the jolt ramming device is also special, is delivered to the very difficult assurance of mould at jolt ramming device place and the accurate location of mold pressing pressure head via conveying device.
