(5A) DEVICE FOR THE MANUFACTURE OF ABRASIVE TOOL

;. ;.. /one :,.

The invention relates to the manufacture of abrasive tools, in particular grinding wheels,

A device for the manufacture of an abrasive tool, made in the form of a mold with a pressing element Itj.

The disadvantage of this site is the low productivity and the impossibility of adjusting the density of the abrasive tool.

The purpose of the invention is to provide a density survey of the abrasive tool.

The goal is achieved by the fact that the device is additionally equipped with a camera with weights freely placed in it and with a concentric mounted mold and with the possibility of elastic interaction with a stationary base, while the camera and the pressing element are equipped with vibrators.

FIG. 1 shows the proposed device, a general view; in fig. 2 view A in FIG. 1: in FIG. 3 is a view B in FIG. one; fig D - section bb in. FIG. one.

The device consists of a mold 1 with a pressing element 2 installed in the chamber 3 with percussion bodies k. The camera is equipped with vibrators 5 and the mouth, 0 is mounted on a stationary base with; help of elastic suspensions 6. The chamber is provided with a lid 7, in which elastic rods 8 are placed around the opening to enter the mold into the zone of vibrating balls. Peripheral rods 8 are placed on the bottom of the chamber. A sleeve 9 with a cone 10 is installed on the bottom of the chamber. 11 and a removable load 12. In the lower part 20, the pressing element is provided with radial ribs 13. On the lid 7 there is a support H with guide rollers 15. Vibrators 11 are usual unbalance vibrators (motorized). Installed oppositely in b Because of the dynamic synchronization, strictly vertical oscillations are provided to the pressing element 2, due to dynamic synchronization, provided that they are angled 0. (See Fig. 3). about -15, and the turn of both vibrators must be carried out in the same direction, the driving forces of the vibrators inform the pressing element 2 vertical displacements along the helical trajectory. Due to the fact that the upper component of the amplitude of the screw oscillations of the pressing element is somewhat greater than its lower component due to the abrasive mass 16 falling under the ribs 13, the twist angle of the pressing element in the horizontal plane as it moves upwards is somewhat larger than the unwinding angle during its movement way down. This makes it possible for the ribs 13 to overlap new sections of the windows between the ribs filled with the abrasive mass 16 for each cycle of movement of the pressing element. Thus, the pressing element makes a rotational movement around the longitudinal axis. As the helix angle increases, the oscillating movements of the pressing element decrease, simultaneously the ribs 13 overlap the large surface of the abrasive mass 16J, which leads to a decrease in the vertical component of the driving force of the vibrators and a decrease in the density of the abrasive mass. Thus, the change in the angle of inclination of the vibration exciters can control the density and hardness of the abrasive tool over a wide range. Claims 1 Abrasive tool making device made as a mold c. a pressing element, so that, in order to control the density of the abrasive tool, the device is additionally equipped with a chamber with weights freely placed in it and a mold installed concentrically and with the possibility of elastic interaction with a fixed base, while the chamber and the pressing element are equipped with vibrators. 2. The device according to claim 1, wherein the chamber is provided with elastic rods installed concentrically along the inner perimeter of the chamber with an interval smaller than the weights. 3. The device according to claim 1, 6 tons, is so that the pressing element is made in the form of a pipe with radial ribs on the lower end, made curvilinear, and on the outer surface in the upper part of the pressing element the vibrators are set at an angle to horizontal plane with the possibility of reporting vertical pressure oscillations along the helix. . A device according to claim 3, in which the pressing member is provided with a set of cargo loads. Sources of information taken into account in the examination 1.
