Description

I

The invention relates to the processing of metals with an abrasive material, in particular to the finishing treatment. Thin toothed discs such as genre saws and can be used in the cotton-cleaning industry.

A device for removing burrs from thin toothed disks of jigsaws is known, comprising a bath filled with a dry abrasive, which is installed in a bathtub with the possibility of a drive shaft. for fixing equal intervals: jinn saws | l.

A disadvantage of the known device is the difficulty of removing burrs from the internal surfaces of the pits of the teeth due to the abrasive material being broken by the saws, especially at high rotational speeds of the saws.

The purpose of the invention is to increase the efficiency of deburring and sealing asperities on the internal surfaces of the tooth troughs.

The goal is achieved by the fact that at the bottom of the bath there are two rows of ribs fixed at an angle to the axis of the bath at the bottom of the bath, symmetrically to its axis and normally to each row parallel to each other.

FIG. 1 shows a general view of the device; FIG. 2 - section AA

0 fig. 1, in FIG. 3 shows a section BB in FIG. one.

The proposed device consists of a bath 1 with a loose abrasive 2 placed in it, a shaft 3 is placed in the bath

With thin toothed disks 4 mounted on it and driven from the electric motor 5. At the bottom of the bath 1, the edges 6 are normally attached to its surface and are included in two rows of ribs 6 that are inter-disk spans and are angled to the planes of the gear disks 4 In this case, the edges 6 in each row are parallel between

and symmetrically relative to the axis of the bath 1.

The device works as follows.

After installing the thin gear discs 4 on the shaft 3, the latter is rotated. Gear discs 4 as vrashenv carry with them loose:. the abrasive 2, which in the zones between the toothed disks 4 and the ribs 6, creates an abrasive underpressure. At the same time, the abrasive particles receive an axial component of the velocity, which contributes to their goniknozheniyu in the hollows of the eubies and their high-quality finish. For more efficient removal of the burrs: either from the submerged or the rear surfaces of the teeth, the 1 process can be repeated with the reverse rotation of the shaft 3.

The use of the invention enhances the effectiveness of deburring and filling of asperities, especially on the inner surfaces of the troughs.
