Description

Until now, all shaped structural circles are pressed with blanks and after drying, the so-called dry turning takes place. Direct pressing of the styles was considered impossible in view of the fact that it was not possible to obtain jf.pyroB with the same hardness at all points.

The proposed mold for jibix grinding wheels differs from the well-known centralHoii application of a spring-loaded mandrel, the shape of a circular cavity formed by a gyu and bounded in axial kneading, with a special stop. This mold, in the opinion of: Inventor, makes it possible to extrude shaped circles, in terms of quality, not inferior to the circles produced by the method that has been used up to now.

In FIG. 1 is a view of the mold at the start of the press; FIG. 2 - at the end of pressing.

The outer cage / support on the gaskets 6, Inside the cage 1 is located at the top of the plate 3 and at the bottom of the ring 2. Between the plate 3 and the ring 2 is placed the mandrel 4, having the shape of a circular cavity and supported on the spring 5, the lower end of which is located on the support S. Mandrel with emphasis fastened by

 nuts 7, probably one foot on the threaded protruding part of the mandrel passing through the stop.

: The height of the outer ring 1 is taken j so that in the compressed position of the mass (Fig. 2) the distance between plate 6 and ring 2 corresponds to the height of the circle, and the distance between plate 5 and mandrel shelf 4 corresponds to the bottom thickness. Before pressing it is necessary to: build a shape on a certain mass. The setting is as follows; here. Know the volume weight of the pressed mass and the volume weight of the mass up to the press; scoops (backfilling), performed next operation. Adjusting guy; This sets the height of the slot (distance between the pressure ring and the mandrel shelf). Under: pads 6 are taken under the outer; clip The height of the corolla filling should be equal to the height of the extruded corolla multiplied by the ratio of the volume weight of the pressed mass to the volume weight of the mass. Gaskets are taken from the calculation of the difference between the height of the filling circle and the pressed circle with the addition of half the fault of the height of the upper plate.
