Description

The invention relates to devices for factory production of building products in the form of concrete mixtures.

Known vibrostamp for the manufacture of building products in the form, consisting of a platform on which is mounted a pressing device composed of a forming plate, vibrators and means for vertical movement of this plate [1].

The disadvantage of this vibroshtami is the impossibility of molding articles of complex configuration and the need for great efforts in molding.

The purpose of the invention is the provision of the possibility of forming articles of complex configuration and reducing the effort during molding.

This goal is achieved by the fact that in the vibrostamp mainly for the manufacture of building products in the form consisting of a platform on which is mounted a pressing device composed of a forming plate, vibrators and means for vertical movement of this plate, the latter is made with

through channels and provided with lifting punches installed in these channels, and means for connecting it with the form.

Moreover, the upper part of the through channel ⁵ in the forming plate is made in the form of a receiving funnel, and the lower working part of the lifting and lowering punch is lined with elastic material.

FIG. I shows vibrostamp for 10 manufacturing of building products in the form, end view; in fig. 2 - section A — A in FIG. one; in fig. 3 - section B — B in FIG. one; in fig. 4 - vibrostamp without forums.

The vibro-stamp contains form 1, plates ¹⁵ form 2, on which is mounted a pressing device 3 composed of a forming plate 4, vibrators 5 and means 6 for vertical movements of the forming plate. Forming plate 20 4 is made with through channels 7 and is equipped with lifting and lowering punches 8 installed in these channels, and means 9 for connecting it with form 1 in the form of clamps or grippers.

part of the through channels 7 is made in the form of a receiving funnel 10, and the lower working part 11 of the lifting and lowering punches is made of elastic material. The punches 8 are mounted on a frame 12 having the possibility of vertical movement by means of lift-lowering means 13 mounted on a forming plate in the form of power cylinders. If necessary, for the convenience of loading concrete mix frame. 12 · can be enclosed in horizontal guides for the possibility of withdrawing it from the zone of through channels 7 of the forming plate 4.

The means 6 for the vertical displacement of the forming plate are made in the form of hinged links 14 mounted on a platform 2 with rollers 15 connected by rods 16 with levers 17 and 18 fixed to a rotating shaft 19 and hydraulic cylinders 20 pivotally connected to levers 17 and 18 and a platform 2. Platform 2 is equipped with drive wheels 21 for moving the vibrostamp along rail tracks to the position above the mold or to the position above the cleaning-lubricating post.

A self-propelled concrete distributor 22 is provided for loading the concrete with a movable shaker and equipped with a movable bunker .23 and a feeder 24.

A building product 25 manufactured by a vibration stamp can be made in the form of a multistage prismatic rack with prestressed reinforcement 26 located in the center of the cross section of a rack or another structure with a complex configuration.

Vibrotamp for the manufacture of building products in the form works as follows.

Form 1 prepared for concreting is installed on a vibrating platform or on shock absorbers. Then a vibrostamp is placed above it. Then the shaped plate 4 means 6 for its vertical movement is lowered onto the form 1 and connected to it, forming a closed cavity 27. The connection of the form with the forming plate is carried out using the means 9 provided for this purpose, in the form of clamps or grippers. I finished this with the inclusion of vibration and filled the closed molding cavity 27 with the concrete mixture. The concrete mixture is fed into the molding cavity through the through channels 7 by loading it into the receiving hoppers 10 with a self-propelled concrete distributor 22. The lifting and lowering punches 8 are removed from the channels and, if necessary, removed from the loading area of the concrete mixture of the receiving funnels 10.

When the molding cavity is filled with a concrete mixture, vibration is carried out by means of vibrators 5 or by means of a vibrating plate together with vibrators 5.

Then, the concrete mix is compacted by repeated immersion of the lifting and lowering punches 8 through the through channels into the molding cavity with vibration and with periodic suppression of the concrete mix into the through channels. Immersion of the punches in the channels of the forming plate is carried out by means of lifting and lowering means 13: After this, the newly formed parts are partially dismantled by lifting the forming plate 4 with the help of lifting means 6 for its vertical movement. Then the form with the products is fed into the steam chamber for heat treatment, and the vibrostamp is moved to the lubricant cleaning station, where the surface of the forming plate adjacent to the products is lubricated and lubricated. This work vibrostamp in the manufacture of building products is finished.

Vibrostamping with a shaping plate, having through channels and equipped with lifting and lowering punches installed in these channels and means for connecting it to the form, ensures the manufacture of building products of complex configuration by forming a closed molding cavity, defining the shape of the products and sealing the concrete mixture by immersing the punches through channels in a closed molding cavity with vibration, and also provides a reduction in the effort during molding due to the possibility of reducing the press uyuschey area.
