SU95344A1 - Device for forming fine grinding wheels from abrasive mass on bakelite bond - Google Patents

Description

The invention relates to devices for forming thin grinding wheels of abrasive mass on a bakelite bond with the same or different length of the center and iericerium. - Lime 1.1 and iHiipoKo iri. Change in the abrasive industry the devices for forming thin grinding wheels with the same and different thicknesses near the center and periphery by manually rolling the abrasive mass on bakelite bond with cylindrical castors.

Oshibinosti described device is the use of smooth conical rollers, rotating the BOKpvr their axes with simultaneous rotation around the central axis of the molded circle. The cone rollers are compatible with the center of the formable TOUKOI-0 grinding wheel. Taicoe decontamination of conical rollers eliminates the formation of thin and L1 foval circles both from the same and from different centers at the center and periphery. Made of thin and lifoBal wheels with different thickness

in zeitra and yernferium, it is achieved by adjusting the angle} K1 of the slope of the axes of the smooth end rollers to the working surface of the molding board. The drawing shows schematically the insulated device.

Smooth coiic rollers / s iodginnnkamn. I on the axles are reinforced by a node of the required angle on traverse 4 so that their tips 1y are aligned with the center of the formable fine grinding Kpyia.

The required weight of the abrasive mass is poured onto the molding plate and is; on bakelite. Traverse 4 or molding yita;; tf in rotation, during which transsa 4 lowers until the distance between the molding plate o and the smooth conical rollers 7 becomes equal to the thickness of the slewing ring. At the end of the molding, the traverse 4 rises and the backwash plate 5 with the grinding wheel 6 which is worn out on it is removed from the molding ring G.

When forming thin Ilyphic circles with different thicknesses near the center and in the non-periphery, a molding plate 5 with a conical working surface is used.

Subject invention

Claims (3)

1. A device for forming thin grinding wheels from an abrasive mass on a bakelite bond using the rolling method, which is so that in order to form thin powder circles both with the same and with different thickness, the rollers at the center and periphery are smooth and conic, rotating around their axes with simultaneous lying about the axis of the molded circle. 2. The form of the device, but also. 1, with the fact that the tops of smooth conical rollers are aligned with the axis of the formable thin circle, and to change the crowd, the circle and the periphery of the rollers are mounted with the possibility of changing the angle of inclination of their axes to working surface of a forming plate. 3. The form of the device according to p. 1, is a t1 with the fact that to obtain different thickness of the circle near the center and the periphery, the working surface of the forming plate is made conical.
