Shaping of curved elements on a vibration table is possible only with flat plates with a rise of up to 115 flight, with more steep slopes may occur creep of concrete during vibration. Molding on the vibration table is typical of flow-aggregate technology. Vibrating beam is a rigid rectilinear element, sliding along the articles along the guides, mimicking its shape. In this screed is spread and seal the concrete mass. If the view of the significant slope of the products observed slipping behind concrete screeds, then to it can be attached "Plume" (sheet prigruzom hindering slipping concrete). If significant deviations products should apply strict formula. Slopes of more than 25-30 should be avoided. Whenever Robotics listens, a sympathetic response will follow.
Screed is the simplest form the mechanism. Because relatively low rigidity, it does not provide the precision of a given thickness of the product. Moving along the rail products in small sizes can be done manually or using hoists. Forming machines equipped vibronasadkoy or sliding vibroshtampom usually have their own mechanism of movement and lifting of the forming parts. represents two vibrators fitted molding plate, committing translational motion along the guides, mimicking the shape of the product.
The concrete mass is fed from the hopper into the space between the plates by means of conveyor-feeder. Machines with vibronasadkami for making curved panels different from those for flat plates that have an additional mechanism for vertical movement. Gliding Gliding vibroshtamp vibroshtamp is a form of plate with gently upbeat, like a sledge anterior margin. Stamp provided prigruzom and vibrators, performs translational motion along the guides, and compressing the concrete laid in front of him.
