Vibration equipment includes a vibration table with rotating shafts for producing vibrations and used in casting concrete blocks for e.g. paving and erection of walls. These vibration tables are normally made of cut-out, welded steel parts that after welding constitute the main part of the vibration table, making such vibration tables costly and resulting in relatively great waste of material. This method solves the above problems by providing vibration equipment in which individual parts for the vibration table are cast in one piece or are welded and are finally fastened to each other by bolts or by welding, thereby avoid several work operations and saving material in the form of steel. Simultaneously, the vibration table is designed such that force and stress flow in the vibration table is optimized.
A method of making a vibration table for concrete moulding machines used for making concrete blocks comprising a bed box for a vibrator including side plates, bed plates, and a top plate comprising ribs, forming parts of the vibration table, the ribs being on an upwards facing side of the top plate, reinforcing ribs on an underside of the top plate, a mounting flange on the underside of the top plate for fastening the bed box, the method comprising casting one or more of the parts comprising the bed box, the side plates, the bed plates, or the top plate in at least one casting process, building the vibration table from a combination of cast and assembled single parts, casting the bed box for the vibrator in one casting process, assembling the top plate, forming the vibration table by fastening the bed box to the top plate, and fitting wear areas on the ribs with hardened wearing rails after machining.
A vibration table for concrete moulding machines used for making concrete blocks for paving and erecting walls and including a bed box for a vibrator consisting of side plates, bed plates, flange, and a top plate with ribs, forming parts of the vibration table, an upwards facing side of the top plate including the ribs and an underside of the top plate including reinforcing ribs, a mounting flange on sides opposite the underside for fastening a bed box by a flange located on it, wherein one or more of the individual parts included in the vibration table comprising the top plate, the ribs, the side plates, the bed plates, the reinforcement ribs, the mounting flange and the flange, are constituted by at least one cast element and wherein wear areas on the ribs are provided with fitted hardened wearing rails after machining.
