Description

The utility model relates to powder metallurgy, in particular to devices for the manufacture of composite interchangeable cutting inserts of various configurations, having several of different layer materials.

A device for the manufacture of cutting inserts containing a housing closed by a fixed cover is mounted on which a powder material dispenser and an ejector matrix are mounted (see the description of the patent of the Russian Federation No. 2047493, B 29 C 43/02/1995).

The known device has limited technological capabilities.

The task is to expand technological capabilities by forming multilayer plates.

This object is achieved in that in the device for the manufacture of cutting inserts containing a housing closed by a fixed cover, on which a powder material dispenser and a matrix with a pusher are mounted, the dispenser is made in the form of nozzles fixed to the cover, aligned with the matrices located on the rim of the rotary disk installed under the cover on a vertical shaft, while the pushers have the ability to interact with the profile surface of the cam lying on the base.

The inventive device is characterized by the presence of the following significant distinguishing features:

a) the dispenser is made in the form of nozzles for powder material;

b) the nozzles are fixed to the cover;

c) nozzles are combined with matrices;

g) the matrix is located on the rim of the rotary disk;

d) the rotary disk is installed under the cover;

f) matrix pushers have the ability to interact with the cam profile surface;

g) the fist lies on the base.

The use of all the features characterizing the claimed device will expand its technological capabilities, i.e. solve the problem.

Conducted research on patent and scientific and technical literature allowed us to conclude that the claimed device meets the patentability criteria of utility models.

The essence of the claimed is illustrated by drawings, where figure 1 shows a device for the manufacture of cutting inserts, its longitudinal section (along aa in figure 2); figure 2 is a top view; figure 3 - scan of the cam; figure 4 is a section along BB in figure 2.

The device comprises a base 1 with a bearing assembly 2 having bearings 3, in which a vertical shaft 4 is installed, placed in a housing 5, closed by a cover 6. At the upper end of the shaft 4, a disk 7 is installed, bearing a rim 8 on which the matrices 9 are located. Below in the matrix 9, spring-loaded pushers 10 are inserted, sliding along the interchangeable cam 11 fixed to the base 1. To introduce the pushers 10 into the matrix 9, a removable sector 12 is located in the cam 11. A base 13 is installed on the base 1. On the cover 6 there are nozzles 14 with PS powder mixtures. The nozzles 14 are equipped with bronze bushings 15 for sealing the gaps between the cover 6 and the rim 8 with the matrices 9. To prevent mixing of the powders in the matrices 9, a plunger 16 is provided. A platform 17 is installed on the stand 13 with the help of a T-shaped connection. the device is equipped with magnetic inserts 18.

The device operates as follows.

At the beginning, the device is prepared for operation, for which powder mixtures of PS of various compositions are filled in nozzles 14, pushers 10 are installed (removing sector 12) and the matrix 9 with magnetic inserts 18.

When the stepper motor is turned on (not shown in the drawing), the shaft 4 rotates (clockwise), entraining the disk 7 with the rim 8 carrying the matrix 9. When the matrix 9 (one of them) is installed at position III, a portion of the powder mixture is poured into it PS, determined by the position of the pusher 10 in height. At the next step (rotation) of the disk 7, the same matrix 9 will fit to position IV, while the pusher 10 will fall down, sliding along the cam 11 by an amount equal to the next layer, and the next portion of the PS powder mixture will be filled into it with a different composition. At position V, the process repeats. It turns out a blank of a cutting insert of three layers of different material. At position VI, the plunger 16 is lowered onto the plate blank. When the matrix 9 approaches position 1, the plunger 10 is lowered below the face with the rim 8, and the plunger 16, also lowering down, prevents the powders from mixing with each other. (The mechanism for installing the plunger 16 in the matrix 9 is not shown in the drawing).

At position VI, the magnetic insert 18 is removed.

At position I, the matrix 9 is moved to the platform 17 and then to the pressing and sintering operations (equipment and processes in the drawing are not shown and are not described in view of their fame).

After the first matrix 9, the remaining five are included in the work, following the first, and the process proceeds in a continuous cycle.

To change the configuration of the plate, it is necessary to change the matrix, rim and pushers on the appropriate.

Claims (1)

A device for the manufacture of cutting inserts, comprising a housing closed by a fixed cover, on which a powder mixture dispenser and a matrix with a pusher are mounted, characterized in that the dispenser is made in the form of nozzles fixed to the stationary cover of the housing, which are aligned with the matrices located on the rim of the rotary disk mounted under cover on a vertical shaft, while the pushers of the matrices are able to interact with the profile surface of the cam lying on the base.
