Description

one

The invention relates to metalworking, and in particular to methods for treating flat products, such as sheets, with cutting tools.

Known methods of processing flat products two incisor beams, which move reciprocating relative to the treated surface.

The disadvantage of this method is that when the incisors strike, the sheets can unfold.

The proposed method differs from the known ones in that the working bodies of the device are made in the form of two located incisal beams, the incisors of each of which are placed between the incisors of the other beams, and the tops of the incisors move along one line.

The treatment is carried out with several pairs of beams spaced along the length of the sheet being processed.

This method provides mutual neutralization of cutting forces.

FIG. 1 image} keno device that implements the proposed method, a longitudinal section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 shows a section according to FIG. one.

The device consists of a frame 1, drive rolls 2, pressure rolls 3, cutting beams 4, support rollers 5, drive 6 beams and drive 7 drive rolls.

On the bed 1, drive rolls 2 are located, which are kinematically connected with drive 7 by means of a chain gear 8.

Four cutting beams 4 are installed in pairs between the rollers 2, resting on supporting rollers 5. Each cutting beam 4 is kinematically connected by means of a fork with an eccentric 9 of the eccentric shaft 10 and with a drive 6.

Cutters 11 are installed on the incisal beam with a certain pitch, the working surface of which is located in the same plane with the drive rolls parallel to the surface of the part 12 to be cleaned.

The incisors of the second beam in relation to the incisors of the first beam are shifted by half a step and mounted console above the surface of the first beam, and their tops are located on one line.

The eccentric shafts of the eccentric shaft are arranged relative to one another in such a way that they provide reciprocating and counter-directional movement of the beams; the first (from the drive) - 0 °, the second - 180 °, the third - 90 °, the fourth - 270 °.

The pressure rollers 3 are mounted on the frame 1 with the possibility of vertical movement and with the help of springs 13 and rocker arms 14 adj: they are attached to the part 12 to be cleaned.

The device works as follows.

When the drive 6 is turned on, the eccentric shaft 10 performs a rotational movement and the eccentrics 9 causes each pair of incisal beams to reciprocate and counter-directionally move.

| When the drive is turned on 7 lower drive rollers make a rotational motion.

The part to be cleaned 12 is laid down lightly on the auxiliary roller conveyor and is fed between the drive 2 and pressure rolls 3. Rollers grab the part and push it first with the first pair of vibrating tool beams, where the cutter 11 basically removes the entire burr, and then above the second pair of beams, intended for final cleaning of the parts.

Cleaned parts going in a continuous flow, go to the second auxiliary

roller conveyor that transports them to the place of packing and storing.

Claims (2)

1. A method of machining flat products, for example, from sheet metal, with two cutting beams that move reciprocatingly relative to the surface to be treated, characterized in that, in order to ensure mutual neutralization of the cutting forces, the incisors of one beam are placed in the gaps between the incisors of the other beam, their tops are located on the same line, and both beams are given a return opposite-directional movement. 2. A method according to claim 1, characterized in that, in order to increase productivity, the treatment is carried out by several pairs of beams, for example two, arranged along the length of the sheet being processed.
