Abstract

The invention relates to mechanical engineering and can be used for finishing and strengthening the processing of parts with granular medium. The aim of the invention is to increase the processing performance by increasing the intensity of the displacement of the mass of the load by providing its relative layer-by-layer movement in the container. The container 2 is elastically mounted on the base 1. At the bottom and walls of the container 2, fins 6 and 7 are installed with screw surfaces 8 and 9. The angles of inclination of the screw surfaces of the bottom edges and side walls are opposite, thereby creating two spaced media one above the other. The counter movement of the medium flows intensifies the processing. 1 hp f-ly, 4 ill.

The invention relates to mechanical engineering and can be used for finishing and strengthening the processing of parts with granular medium.

The purpose of the invention is to increase the productivity of the treatment process by increasing the intensity of mixing of the mass of the load by providing its relative layer-by-layer movement in the container.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The device consists of a container 2 elastically installed on the base I with a storage chamber 3 for the working medium, overlapped with a removable dividing grid 4 and communicating with the container 2 through a window 5 located at its bottom and with transporting means made in the form of mounted on the bottom and side walls of the container 2 ribs 6 and 7 with screw surfaces 8 and 9, with the ribs 6 mounted on the bottom of the container 2 located by the screw surface 8 in the direction opposite to the direction of the screw surface 9 ribs 7 mounted on its side walls. In the lower part of the container mounted vibrators 10.

The device works as follows.

Container 2 is loaded with a work environment and workpieces. After that, the vibrators 10 are turned on, which drive the container 2 into an oscillating motion, and the mass of the load receives a circulating motion. When the mass of the charge circulates in the container 2, the ribs 6 and 7 of the screw surfaces 8 and 9 divide the mass of the load into two streams located one above the other, directed along the container in opposite directions. Moreover, the upper flow is directed towards the separation grid 4, and the lower - in the opposite direction. When this occurs, intensive movement of the mass of the load, as well as its effective output from the cumulative chamber 3 through the window 5.

The device can be implemented as a periodic mode of processing, and continuous. In the batch mode, the treatment is performed while the separation grid 4 is removed. During the processing, the mass of loading circulating across the container (working medium and workpieces) is divided into two opposing streams located one above the other. At the top, the upper flow through the ribs 7 is directed towards the accumulation chamber 3, and the lower stream - from the accumulation chamber 3 through the window 5 through the ribs 6 along this part of the container 2 to the opposite side. At the same time, the machined parts at

the movement may reach the opposite end wall of the container 2 and may not reach it and be mixed in any place along the length of the container, passing the bottom zone, where the processing efficiency is increased due to the presence of counter flows. Thus, the parts can repeatedly fall into the accumulative chamber 3 and exit from it along the bottom of the container 2. As the parts change their position along the container cross section, and the processing conditions are the same along the length of the container, all parts are uniformly processed.

After the processing cycle, a dividing grid 4 is installed, through which the machined parts extend beyond the container, the working medium passes through the grid 4 into the collection chamber 3, and from there into the working cavity of the container 2. After the separation process, the grid 4 is removed and the new batch is loaded details, after which the processing cycle is repeated.

In the continuous mode, the processing is carried out with the dividing grid 4 permanently installed. In this case, the parts are loaded near the end wall of the container 2 located on the opposite side of the dividing grid 4. The mechanics of moving the loading mass in the continuous mode are the same as in the periodic mode. However, taking into account that in continuous mode each part must reach the parting grid already fully machined, it is necessary to provide the required time for moving parts from the place of loading to the parting grid. This is done by the vibration modes, the angle of inclination of the ribs 6 and 7, and the length of the container 2.
