Description

Bidirectional pressing-vibrating type building block shaping machine
Technical field
The present invention relates to the former of a kind of building block or brick, especially a kind of bidirectional pressing-vibrating type building block shaping machine.
Background technology
The block machine that uses on the current market all is unidirectional compression moulding.Chinese patent publication number: CN1234322, open day: on November 10th, 1999, denomination of invention " automatic pressing machine for blind multi-hole building-blocks "; A kind of employing underlying vibration core bar and lower die head pressurization have been proposed, the technical scheme of unidirectional complex vibration and plasticity extrusion modling, it can adopt sand, flyash, slag, loess, cement etc. to produce unburned porous building-brick; Also can produce sintered porous building block with clay inferior, simple in structure, reliable; The intensity of its goods is higher, and hollow rate is high.
Chinese patent notification number: CN 2275028Y; The day for announcing: on February 25th, 1998; Utility model title " building-block two-way forming machine "; Proposed a kind of with blank pressed compact device with become base pressed compact device to be assembled in the two ends of screw rod in the screw actuator respectively, through frame with blank building block mould or become base building block mould to tighten up, connect the technical scheme that forms.Prime mover drives screw rod and alternately does axially-movable to two ends, and it is bad with hair with the material mud that becomes base pressed compact device to replace in the extrusion die to promote blank pressed compact device, processes the packing height, the plurality of specifications half-blindness hole building-block that intensity is big.In this technical scheme as far as the blank building block mould that is positioned at the screw rod two ends with become base building block mould, the pressed compact device is still unidirectional pressed form.
Unidirectional compacting formula equipment to produce brick as shown in Figure 1, above-mentioned, its molding mode all is that material is placed in the moulding box 1; The bottom of moulding box 1 is provided with moulding box base plate 27, makes moulding box 1 form unidirectional opening, and goods are by the inside unidirectional pressurized of opening part during moulding; Pressure from top to bottom transmits, and in pressing process, receives the extrusion friction effect meeting of moulding box 1 frame wall to produce pressure loss, and the pressure that goods bear successively decreases from top to bottom; Minimum to moulding box base plate 27 site pressure, make the intensity up and down of goods inhomogeneous.Its goods in use can receive the load power consistent with pressing direction; But the actual compression strength of goods is the intensity with weak spot to be showed; Therefore, in the uneven building block product material of intensity up and down, high-intensity part is a kind of waste to resource.In addition; How within it building block product portion processes hollow-core construction; Because the formation of the hollow body of building-block or brick is to be realized by the inner space that the core rod body in the moulding box 1 occupies goods, and the core rod of mould must be through the lock piece polyphone location of mould, the steric restriction that its crossbeam occupies in the production process raw material get into the path of moulding box 1; Simultaneously; Even more serious is, and pressure head 2 receives cutting apart of core rod lock piece can only be several independently pressure faces, and building block product can not get the on-line operation pressure of pressure head 2 being positioned at the plane that the mould beam covers, thus cause in the section of goods, forming compact zone A, be the under-voltage band of V-type than compact zone B and serious ravel area C.Owing to be not under pressure, the internal structure of goods is loose in serious ravel area C, and its compression strength is far below compact zone A, and this can make the entire compression intensity of goods decline to a great extent.
Comprehensively above-mentioned; Unidirectional pressurization on the horizontal plane of material makes the compression strength of shaping building block or tile product present strong weak down state, and the serious ravel area C that pressure head 2 forms in moulding box 1; Strong down a little less than making on the local compression strength of goods again, both can't carry out complementation again on the whole.In intensity test and practical application, often the weakest aspect of intensity or partial points position begin defeated and dispersed from the goods; And moulding box 1 fixedly installs in the equipment, and the frictional force during product molding is big, and required static pressure is bigger, and the power of equipment and energy consumption are high; Being provided with of core rod beam can cause occurring on the goods the serious ravel area C of intensity extreme difference, thereby influences the bulk strength and the Forming Quality of goods.
Summary of the invention
It is high to the objective of the invention is to overcome existing equipment to produce brick power and energy consumption, and pressure is even inadequately, its building block product inconsistent defective of each position intensity and deficiency; Provide a kind of pressure power of shaking lower; Block forming intensity is even, and packing is high, can make many rounds building-block or brick; Hollow rate is higher, the bidirectional pressing-vibrating type building block shaping machine of conservation.
