Description

I 11

The invention relates to the processing of materials by cutting and can be used for transverse cutting and cutting of lengthy material, such as elastic plastic tubes.

The purpose of the invention is to expand the range of lengths of cut pieces.

FIG. 1 shows a device, a longitudinal section; FIG. 2 is a view A of FIG. 1j Ya fiyg. 3 - screw working part; o g FIG. 4 shows a scan of the outer surface of the drum and the configuration of the jetting groove.

The device contains a support 1 with a channel 2 for placing the material being cut and a sub-element in the form of a hollow drum 3 installed parallel to the axis of the channel 2 with a longitudinal curvilinear guide groove 4. One wall 5 of the drum 3 is rigidly fixed on the shaft 6, and in a wave on a movable liner 7 mounted with the possibility of moving along the shaft 6. On the generator of the drum 3, the working part 8 is fixed with one end, the second end 9 with the blade 10 is installed in the guide groove 4 and fixed on the insert liner 7.,

Channel 2 in support 1 is formed by a fixed chute 11 and axially movable chute 12, which is mounted on a bearing 13 on a movable insert 7.

The end 9 of the screw working part 8 partially overlaps with a blade. 10th channel 2. 2.

On the wall 5 at the exit of the channel 2 is fixed the end 14 of the working part 8

and set the movable knife 15 for the final cut with the blade 16,

The device works as follows.

5 The drum 3 is set to rotate together with the insert 7 and the screw working part 8 with the blade 10 and feeds the material 17 into the channel 2. The blade 10, the intersection located in channel 2

0 part of the cross section of the material 17, incised last. Rotating, the working part 8 moves along the notch and; feeds material 17 to blade 16, which deepens the cut or cuts material 17 completely. At the same time, blade 10 cuts material 17 again and the process repeats.

Moving along the shaft 6 of the insert 7 with the end 9 fixed on it

With the screw working part, the distance along the axis between the ends 9 and 14 of the working part can be changed. In this way, the length of the material being cut is controlled.

5 Due to the curvature 4 of the guide groove 4, the edges of which are made along radii equal to the length of the unfolded screw portion of the working part (Fig. 4), and the centers of the radius of the diameters lie in the plane of end 14 and are displaced one relative to the other by the value of end 9 the latter compensates for the divergence of the ends of the working part in a plane perpendicular to the axis of rotation.

For processing materials of other sizes, additional channels with corresponding dimensions may be provided in the support.
