(54) DEVICE FOR CLEANING PARTS PARTS

one

The invention relates to the field of mechanical processing of removing burrs and cleaning parts having different shapes and sizes, and can be used in engineering and other industries.

According to the main author. St. No. 2,63836, a device for cleaning workpieces is known, comprising a rotating drum with a casing, on the inner surface of which there are partitions dividing the drum into sections 1.

A disadvantage of the known device is the complexity of its design.

The purpose of the invention is to simplify the device.

This goal is achieved by the fact that the windows in the casing partitions are located on either side of the axis of rotation of the drum in a staggered order, while the device is equipped with a screw conveyor.

FIG. 1 schematically shows a tumbling drum, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3- section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of the FIG. four.

The tumbling drum consists of a body t and end walls 2 and 3. The body 1 is made of two shells, the cavity 4 between which is filled with a sound-absorbing liquid. The drum has a slope to the unloading window and is mounted with rims 5 on base rollers 6. On the end wall 3 there is mounted a device for unloading workpieces, consisting of two blades 7 fixedly mounted, and a screw 8 with two windows 9 on its cylindrical surface, into which the parts roll off the blade 10 current 7 and fall on the spiral of the screw. The tedders 10 are mounted on the inner surface of the drum along its axis. In order to keep the parts moving from loading to unloading in the drum, segment dividers 11 with windows 12 are installed overlapping most of the drum section.

Tumbling drum works as follows.

At the initial moment of operation of the drum, the screw 8 is rotated and fixed against a relatively empty drum so that the windows 9 on the cylindrical part of the screw are closed by the cylindrical part 13 of the end wall 3.

Portions of the parts 14 are loaded through a window in the end wall 2 into the rotating drum to a level at which the windows formed by the segment partitions I overlap with the level of the parts. The feeding of parts is stopped and the parts are trimmed during the time set by the process.

After the tumbling time has passed, the screw 8 is rotated and the windows 9 open for parts falling from the blades 7 onto the inclined surface 15 and further onto the spiral of the screw which moves them to the outlet of the drum. By turning the auger, you can adjust the size of the window 9, and hence the productivity of unloading parts from the drum. After installing and fixing the required discharge capacity, the drum is operated in automatic mode, which requires loading the parts into the drum with a capacity close to the performance of unloading parts from the drum.

When the drum is in automatic mode, the details are due to the presence of windows 12

in the dividers 11, they regularly pass through the entire length of the drum, i.e., the tumbling time observed by the process is observed.

The expected economic effect from the use of the proposed device in one enterprise will be about 50 thousand rubles.
