SU139798A1 - Hollow Core Slabs - Google Patents

Description

Devices are known for making hollow slabs of wood waste with minerals 5 in the binder, and similar materials, including a support plate, a shape from longitudinal and end walls, vertical vibrating cores-hollow cores, a tray with openings for hollow cores and a lid, as well as above the form, a lifting mechanism with a crossbeam to lift the device in the process of vibropressing and to disassemble the formed nzdel.

The described invention relates to the same kind of devices and aims at facilitating the construction by using the weight of a part of the device (base plate, longitudinal walls of the mold, vibrating cores, a lid) for pressing the mass. This is achieved by the fact that the vibrating hearts and the longitudinal walls of the mold are rigidly attached to the base plate, and the pallet is attached to the end walls of the mold, and during the vibropressing process the device is lifted beyond the end-e walls of the mold and the flap is attached to its longitudinal walls. 1 schematically shows a general view of the device; in fig. 2- side view of the forming unit; in fig. 3 - its section in the vertskalnoy plane.

The device consists of a base plate 1 on which the longitudinal walls of the form 2 and the spring-loaded frame 3 are rigidly attached, carrying the vibrating-hearts 4 and the vibrators 5 mounted on it. The form has a sliding part 6, which is a frame consisting of longitudinal elements 7, connected by transverse axles 8, and the end walls 9 of the form with the engaging pallet 10 by the legs T1 and the rotary handles 12. The end walls of the form have stiffening ribs 18 and can be rotated relative to the axes 8 or fixedly eny. When pressing on the sliding part of the form, the unequal arms of the arms 14, which with their short arms carrying the rollers (5), abut against the flanges / (; on the longitudinal walls of the mold, and the long arms of the arms are connected by means of

L 139798- 2 cables / 7 with ipaBepcoii 18 lifting and power mechanism (not shown in the drawing). The traverse, in addition to the non-transmission of forces on the levers M, carries the lid 19, connecting with it the hooks 20. At the right moment, the lid is placed on the mold, detached from the traverse and connected to the form by locks 21, representing arcs, fitted with weights and set on the axis about the hook fingers. For simultaneous production in the form of several products, it is provided with a longitudinal partition wall 22, fixed on the crossbars 23.

The operation of the device for the manufacture of plates is as follows.

The noddon 10 is descended into the mold. It is a section metal section connected at the ends, having openings for the passage of hollow cores and equipped with rollers for rolling in the guides of the pre-hardening chamber. After this, the form is filled with a mixture from a hopper 24 for switching on of vibration.

The mixture is aligned on top of the mold, after which the lid is lowered onto it, which is fastened to the mold with locks 2 and a force mechanism is activated that acts on the sliding part of the form, as a result of which the mixture between the lid and the pallet will be pressed while the vibrating formers continue to vibrate.

The pressing takes place until the holes until the whole form starts to rise together with the reinforced concrete slab.

When the extrusion 18 is pressed, the traverse 18 is lowered onto the lid 19, fascinates it, and after ottsenie from the form rises together with the lid, in the process which also removes products from the form. Then, under the pallet with products, horizontally consoles 25 of the guiding paths of the pre-hardening chamber 26 are pivoted in the horizontal plane, but which are rolled into the product ket, after the end walls are detached.

Further advancement of the pallets in the chamber is carried out by paws 27, which push them, being hooked on by a lift-power mechanism.

The molding process is repeated after the freed PODI1 is fed to the mold along a sloping path 28 located under the chamber.

PREVIEW

A device for the production of hollow slabs from; mineral waste into zhupim and the like materials, including support nlit, shape of longitudinal and end walls, vertical vibrocord-hollow cores, tray with holes, for hollow cores and lid, and also located above the mold a lifting mechanism with a crossbeam to lift the device in the process of vibropressing and to remove the molded product, characterized in that, in order to facilitate the construction by using the weight of the part, Features (support plate, longitudinal walls of the mold, vibrating hearts, cover) for pressing the mass, vibrating hearts and longitudinal walls of the mold are rigidly attached to the onopH: jM pnite, and the pallet - to the end walls of the mold, and in the process of viopressing the device is lifted behind the end walls and the cover is attached to its longitudinal walls.
