Description

The author's certificate N ° 58941 describes a device for filling and leveling the mass in molds for pressing grinding wheels. In this device, under the bunker that does not have a bottom, there is a fixed ruler and a rotating disk for feeding the mass from the bunker to the rotating sleeve, located above the bed to be filled. The sleeve carries a spiral blade outside to level the mass in the mold by moving it from the edges to the center.

The device for leveling the mass in the proposed form is made as follows. Two blades of form, respectively, spaced between the mandrel and the outer ring, are connected with the rotating rod by means of which the mass moves both from the edges to the center of the form and in the opposite direction.

FIG. 1 is a side view of the device; in fig. 2 is a horizontal section through it a-a in FIG. I,

The spindle / is mounted in the guides 6, which are connected to the lever 7, which is hingedly fastened at the press. At the end of the pinch there are two lonasty 2 and 3 fastened together. Blade

3- is concave at one end - it reaches the outer ring of the 5th form, while the other ring does not reach the mandrel of the 4th form. The other blade 2 - is convex - the inner end reaches the mandrel

4pressforms, and the other, outer, end does not reach the outer ring 5 of the form.

A receiver funnel or sleeve 9 is attached to the bracket 8 carrying the blades. A screw 10 serves to adjust the height of the blades.

This device is quite suitable and convenient for mass distribution in forms with low circles. In the case of processing the mass for high circles, it is necessary not to rotate the blades and the sleeve, but to rotate the form fixed on a special table. In this case, the blades with a sleeve

strengthened permanently, providing them with vertical movement depending on the filling mass

forms.

When working on the molding table 11, the mold is set centrally about the spindle / device axis. Raise the blade with your hand, put it into shape. Under its own weight, the blades are lowered all the way into the adjusting screw to a predetermined level (along the height of the circle). The weight, weighed in advance, poured into the sleeve 9. When rotating the spindle / by the handle, the 12 blades and the sleeve will also rotate. The mass is poured out of the sleeve and, with a concave blade 5, is distributed in shape from the periphery to the center, forming an annular mass accumulation at the mandrel of the form. The convex blade 2 will capture the mass that is

mandrel, and distribute it on the plane of the form from the center to the periphery. Thus, the entire mass found in the sleeve will be evenly distributed in shape.

Subject invention

The shape of the device according to the author's certificate No. 58941, characterized in that, in order to move the mass from the edges to the center of the form, and in the opposite direction, two blades 2 and 3 are connected with sleeve 9, of which the blade 2 is convex the direction of rotation — one end reaches the mandrel 4 of the form, and the other does not reach the outer ring 5 of the form, and the blade 3 — concave — and with its ends, on the contrary, does not reach the mandrel 4, but reaches the outer ring 5.
