Description

one

The invention relates to the field of metalworking.

A known cutter with a mechanical fastening of a cutting insert mounted on a lining and secured by means of a ngfift passing through the apertures of the insert on the lining and a wedge element

one.

However, this cutter does not provide a case of fastening the cutting plates of any shape, for example in the form of a piece.

The aim of the invention is to secure the fixation of cutting forms of any form of ilastin.

For this, in the proposed cutter, the iodine lining and the cutting plate are rigidly connected by means of protrusions and grooves, the tongue is pressed into the lining, and the MeiiT wedge element is made so that its side surface contacts the side surface of the lining.

FIG. 1 shows the proposed cutter, a longitudinal section; in fig. 2 - knot on the knot, transverse section; on phpg. 3- cutter with a cutting plate in the cup cup, longitudinal section.

The multifaceted plastic cutting 1 is made in the plane of abutment with the protrusions 2 entering the grooves 3 of the metal lining 4 mounted on the holder 5, and pressed to the holder 5 by the pin head 6, which is pressed into the iodine lining 4 and freely passes through the holes

in myogograpy cutting plate 1 and the holder 5. Plate 1 together with the lining 4 is attached to the holder 5 by the clip element 7 with the clamping screw 8. When the screw 8 is tightened, the wedge element 7, moving along the bevel of the holder 5, presses the lining 4 with the multi insert cutting plate to the walls of the hole in the holder 5 and due to wedging creates a stiffness of fastening.

Such a construction of the cutter ensures reliable fastening of the multifaceted cutting nlastina regardless of its shape.
