The invention relates to mechanical engineering and can be used for finishing, grinding and hardening the processing of parts in a free state.

The purpose of the invention is to reduce the dimensions of the device along the length, as well as improving performance by reducing the energy intensity of the collisions when processing parts with high rigidity and increasing the flow area of the drum.

FIG. 1 shows a tumbling device, a general view; in fig. 2 section A-A in FIG. 1; in fig. 3 tumbling drum; in fig. 4 shows a section BB in FIG. 3

The device consists of a bed 1 ,. made in the form of a welded frame. The main drive is fixed on the frame, consisting of an electric motor 2, a gearbox 3 and four roller bearings 4. The tumbling drum 5 is assembled from sections 6, each of which is formed from equilateral triangles 7 that are identical in area and connected in side section faces 8 and 9, and each section with each other along the length of the column is connected by bases of 10 triangles 7, Tumbling drum 5 is equipped with two rims 11, which are supported on roller supports 4 with flanges.

On the frame 1 mounted means for loading 12 and unloading 13, as well as the hopper 14 for waste. Above the bunker 14 in the tumbling drum 5 there are holes 15 for waste disposal (blister, burr metal, scale, etc.). The bed 1 is mounted on the supports 16 of the support plate 17 with the ability to adjust the inclination using the adjusting bolts 18. The change of the angle of inclination is carried out in order to regulate the speed of movement of the processed parts from loading to unloading.

The vertices of triangles 7 form clear right and left helixes. · For example, positions 19-27 marked

one of the right helix lines, and the 28, 29, 21, 30, 31, 32, 33, .26, 34 positions is one of the left helix lines.

The device works as follows

In tumbling drum 5 through. > 'means 12 for loading continuously loading the working environment and the parts to be processed.

During the rotation of the drum, the working medium and the workpieces perform a complex spatial movement along helical lines and are unloaded from the drum 5 into the means 13 for unloading.

Since the tumbling drum 5 is equipped with helix lines of equal pitch, directed one towards the other, load flows are created in the drum, directed one towards the other with the maximum possible energy consumption of collisions, and the time spent for the load (working medium and workpieces) the movement of the load in the helical column from loading to unloading is regulated by the inclination of the bed 1 and the tied drum 5 fixed on it relative to the horizontal support plate 17 by rotating the bed 1 in the supports 16 with the help of Adjustment bolts 18.
