Description

A working member of the molding machine for vertical vibroforming of reinforced concrete products is known, which includes a vibro-comb and calibrates vibro-vibrators with vibrators 5 of directional action suspended along their ends. The purpose of the invention is to increase productivity, improve product quality and operating conditions. This is achieved by the fact that the vibratory cages and calibrating vibrating bars are located in one uiaHe and that the trowel bars and dampers are mounted with a gap, each of which is independent of the frame of the molding machine, with the help of an independent plate spring the width of all vibratory dies calibrating damper bars-dampers is the same; The end edges of the side faces of the vibrating bars are angled at an acute angle, and the upper edges of the trowel bars and dampers are equipped with sharp chamfers, which will transform their side faces into vertical planes; In addition, in order to prevent the flow of concrete between the vibrator and the damper bar, the lower edges of the blades of the vibro-comb are located VA / A-A above the lower edges of the side faces. FIG. 1 shows the proposed working body, general view; pas figs. 2 is a section along the AL in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 shows a section along B-5 and FIG. 2; Hia FIG. 5 is a section along BB in FIG. 2; in fig. 6 — node II in FIG. one; in fig. 7 shows the node III in FIG. 1. The working body of the machine for molding concrete products, for example, flat products. panels, consists of i vibro-comb / and Z2 Zi-fl vibrobrus 2, under each of which a trowel bar-damper 5 is installed with a small gap. The total number of mashing vibro-dampers-dampers Z -Z - + Z2 n + l, where n is a number, multiple 2 (the number of simultaneously molded panels), All VIbrogrebenk / and vibrating bar 2 and bars-dampers 5 at the ends through the matte matte are suspended to the frame 4 of the vertical molding machine through flat vertical springs 5 to 6 of the stretch, To one of the ends of the vibro-comb / vibrobrus 2 and damper bars 3 rigidly attached vi 7th to 8th directional action. Combs of the vibro-comb / made in the form of separate sections with the base I have been detachably mounted on the lateral edges of the vibro-comb /. 3-5 such sections are installed along the length of the vibro-comb.

The blades of the vibro-comb / are arranged so that their ends are lower than the lower edges of the lateral forming and gage faces in the rower.

The lateral faces of the vibrocooter / vibrobrus 2, beneath the trowel bars 3, are located, respectively, in strictly vertical planes parallel to each other.

The upper edges of the hulls of the vibrator maker / and vybrobrusev 2, as well as all the damper bars 5 are located respectively at the same level.

The ratio of height to width of all buildings of the vibratory comb / vibrating bar 2 and damping bars 3 is close to 1.

The hull of the vibro-crib /, vibrobrus 2 and bar-demluffers 3 Made of stainless steel by stainless steel, have transverse lightweight cords, and their side vertical edges are machined. The width of the housing is a vibrating dribble and wide; at least 430 mm beams are taken.

For adjusting the thickness of the molded products, the vibro-comb 1 and the vibrating bar 2 and 3: The solid bars - dampers 3 are rigidly connected via springs 5 to 6 through movable pads / (and // with fixed slats 12 and 13, having T-shaped grooves.

The device works as follows. When turning on the end vibrators 7 and S of directional action, the concrete mix is continuously and evenly fed into the gaps between the vibrating mats 7 and the vibrating bars 2, while simultaneously raising the frame or lowering the contour tooling.

Under the action of vibration, the vibrocrest concrete becomes motile, compacted and at the same time calibrated to the thickness of the plate (panel) being formed.

Under the action of the longitudinal tangential vibration of the side faces of the vibrating comb. vibro-bar 2 and damper bars 3 friction decreases sharply. At the same time, the solution and air bubbles are released on the surface, which burst after exiting

Forming faces of the vibrating comb / and vibrating bars 2, form small shells, partially filled with cement-sand mortar (see Fig. 3), and then finally rubbed with wetted vibrator bars 3 below.

After the molding is completed, the cart with the forming panels is rolled away without waiting for the concrete to harden, and the next batch of contour snap-ins on the cart is fed into the forming unit.
