NON-FIRM SOLID-SHAPED CLOSING PLATE

The utility model relates to the tool industry, and more particularly to the production of solid tools for cutting tools, in particular mills and cutters.

The hard and shavier neurotetrachable mechanically forbidden plastics are widely known under GOST GOST, GOST "GOST, GOST" GOST.

In the treasury of the closest analogue, a hard alloy is used that is not mechanically grinded with crêpe alloys and is made of alastish, with a cutting and supporting support, and a through hole, equipped with a roaring and support surface from the outside with open fangled holes 004 C cm, Г0РТ 19042 “80 plates of form 0, J, U. )

Design14 of these STYZ PD data envisages sharpening the A1L forging at the Yzgoto factory: the windshield and the installation are not additionally harnessed in the tool case, they turn the plastra as it wears out, use all its grandees, after which it will be delivered to the factory | I'm recycling

However, since the data are built on but not provided for their regrinding, noigifoi the thickness of the data is chosen at the least necessary, based on the need for shielding and stiffness.

In addition, fr, the pma of these adastins is not redirected to tearing its second side saddlery as tearing, i.e. not expensively used expensive alloy.

Epj "this is even a through hole with a long" distant shape is not reliable enough; | Because of the extreme loads during operation of the tool, the element “with countersunk head” is unscrewed because the shape of the seat does not restrict the screw from turning,

In a nutshell, the technical result, the solution of which is useful for this utility model, is to increase the reliability of the cohesion of a carbide carbide cutting tool to save expensive hard alloy; In addition, another technical result ||

KOTopoiro Nai Avlena's solution A useful model is to expand the assortment of products manufactured by industry | Predetermined non-deflectable inserts for mechanical fastening The indicated technical results are achieved by 0 in a well-known hard-hardened, machined mechanically fastened plate containing a cutting and supporting shaft and a through hole located between them, provided with a mounting support on the side of the supporting surface of the support and mounting seats under it for mounting made through hole, according to the useful mideli.

settlement sites are wide in the form of grooves extended along one of the dimensions of the grooved plate and are intended for a mounting edemit with similar dimensions, and paccTOpti e between the bottom surfaces of these grooves are determined by the subformula:

C.-dl-, where

with ". distance between the bottom surfaces of KjaHaBOK; gf B - diameter: in the hole

04 is the diameter of the circle inscribed in the projection of the plate on the plane; H plate thickness.

The implementation of the seats in the form of elongated along one of the dimensions of the plate grooves, designed for an element with a head znalogologichnsh e profidya. allows to ensure reliable fastening of the solid plate in the cutting tool 1 m, This is achieved due to the fact that the elongated shape of the seats does not allow the screw to be folded, which is also made elongated.

In this case, the presence of V grooves of such a form allows one to significantly save the costly solid joint.

It has been experimentally established that the distance between the bottom layers of these grooves, determined by the ps of the claimed formula, makes it possible to ensure the reliability of this layer, its strength and rigidity.

The set of essential features of the claimed technical solution of the device differs from that of the analogue and, according to the applicant, meets the requirement of novelty /

These plates can be widely used in the tool industry, therefore, the object meets the requirements of industrial applicability. The utility model is illustrated by merchants. In Fig.
