Definitions
- the machine has a steel structure, composed of various parts, which functions by sliding along a two-lined track (6). It can be placed directly on the ground or on a raised metal structure and has a piece of heated sheet metal at its base in order to speed up the drying process of the product
- the distance between the tracks essentially depends upon the type of floor slab that one intends to make with the extruder.
- the structure is composed in the following way:
- a power unit - speed reducer (2) which serves to set the feed pushe in motion (3).
- This unit is anchored to a supporting structure (4), which in turn is joined to the supporting side members.
- At the ends of these members there are two pairs of wheels (5) which rest on two tracks (6) and are supported by uprights that may be adjusted in height (7).
- the power unit - speed reducer sets in motion an axle (8), which has a cam at its lower end, fitted inside the truck (10). This truck is able to slide forwards and backwards with a movement that is equivalent to twice the eccentricity of the cam (11). This is made possible by the presence of four wheels which are kept in line by two guides (12), joined to the body of the machine.
- a feed pusher (3) which is made up of an appropriate number of metal sheets (13), set apart at varying distances according to the type of shape required. These metal sheets are attached at one end by an 'L' shaped compacting plate.
- the vertical part of this (15) serves to press and consolidate the material being worked, while the horizontal part (16) serves to open and close the mouth which takes in the material.
- This mouth is merely the lower opening of the hopper (17) which contains the concrete.
- the plate (16) which opens and closes the mouth of the hopper, slides against a scraper (31), preventing the
- a comb (20) In the existing space between the power unit - speed reducer (2) and hopper (17) is a comb (20) to which the moulding tubes (21) and finishing tubes (22) are attached elastically through means of rubber supports.
- the tubes in turn are linked by a rubber ring (26).
- Every moulding tube is provided with a vibrator (23) so that each one may be adjusted by increasing or diminishing the vibration, depending on the quality of the extruded item.
- the moulding tube (21) does not have a constant section, but the part into which the material to be worked drops has smaller dimensions to allow a greater quantity of concrete to drop through. At the tip, where the worked material comes out, the section progressively increases until it arrives at the definitive form of the article to be produced.
- the vibrating plate is equipped with a unidirectional vibrator (27) which produces an exclusively vertical vibration of the plate itself.
- the link between the vibrating plate and beams connecting the turrets is achieved through two series of flexible rubber supports (28).
- the concrete mix is brought to an optimal level of surface and internal finishing, using the finishing plate (29) and internal finishing tubes (22).
- the finishing plate is formed by a solid steel structure which smoothens the upper surface of the concrete and effects an ulterior, though minimal compaction, reducing by a further few millimetres the volume taken up by the concrete. It is connected to the side members of the machine by two turrets (31), similar to those used for the vibrating plate unit.
- the tip of the finishing tube which is connected to the moulding tube, has the same dimensions. Instead, the part where the item is expelled has smaller dimensions. This determines a gradual decrease in the compression of the concrete which can smoothly slide down these and obtain perfect internal uniformity.
- weights (23) are applied to the ends of the latter, adequately sized to dampen unwanted vibrations.
- the form of the section bar's sides is obtained through means of two side panels (24) which are joined to the two side members of the machine (1).
- the profile of the side panels starting from the point where the material to be worked drops, as in the case of the moulding tubes, progressively narrows so that the concrete is highly compressed until it arrives at the dimensions of the final product.
- a counterweight (25) with dimensions that ensure proper adherence to the track and prevent upward vertical pressure, determined by the force of the feed pusher on the concrete being worked.
- the side members (1) contain two other members within, which are fixed together with bolts. It is interesting to note that by removing these bolts and those which link the truck to the feed pusher's sheets of metal (13), one is very quickly able to substitute the die in order to produce concrete floor slabs with different dimensions and characteristics.
- the power unit - speed reducer sets the camshaft in rotatory motion. This in turn sets the truck in motion which transforms the rotatory motion into alternated rectilinear motion.
- the truck then triggers off the feed pusher, which in the first phase of the work cycle, moves backwards together with the truck twice the distance of the cams' eccentricity. This movement determines the opening of the compacting plate of the hopper's mouth and consequent fall of concrete into the space between the moulding side panels and moulding tubes.
- the cam completes its rotation the truck moves back to where it was previously as do the feed pusher and compacting plate.
- the form is cut using appropriately sized saws which move through means of the same tacks used by the prestressed reinforced concrete floor slab machine.
- the main disadvantage with the second type lies in the fact that the finished product is not sufficiently resistant, since compaction is effected exclusively through vibrators.
