(54) DEVICE FOR BRANDING

The invention relates to a device for metal forming and can be used for impact stamp products, such as ingots and rolled products. A device for stamping parts at the end is known, comprising a cylindrical body with a striker accommodated therein, and a marking head with a set of marks fl. However, this device cannot brand irregular surfaces. A device for a brand containing a piston rod-mounted in a housing that can be mounted, a glue holder with a set of independent axial movement, and a mechanism for transferring force from the stock piston to the stamps, made in the form of a set of percussion elements according to the number of brands installed with an independent The displacement of T J The disadvantage of this device is the complexity of the mechanism for transferring the force, which reduces the reliability of the device. The purpose of the invention is to simplify the cong structure. The goal is achieved by the fact that, in the device for the brand, the impact elements are made in the form of rods mounted in a piston rod. The percussion mechanism is made in the form of a rod-piston - equipped with rods installed coaxially with marking marks with the possibility of longitudinal movement relative to each other. In FIG. 1 shows the proposed device, general view, section; figure 2 is the same, a schematic image; in fig. 3 shows section A-A in FIG. one. , . The device consists of a housing 1 with a percussion mechanism placed in it, made in the form of a rod-port 2, serving as an acceleration device for the rods 3, the number of which is determined by the maximum number of characters 4 included in the marking (up to 32 characters). the cassette 5 located in the cassette 6. The rods 3 at one end abut against the street gasket 7, the other end is free. Kazvda rod installed coaxially with the socket of the marking mark 4 with the possibility of longitudinal movement relative to each other. Zaok 8 fixes the rod 3 from falling out. The ends of the rods resting on the right side of the tab 7 are made with protrusions 9, marked in the undercut of the piston rod 2 to ensure the return of the rods

3 when marking the next billet. The body 1 is fixed on the uprights 10 on the middle of the semi-axes 11 and with the clamp 12 is installed at an angle to the horizon. The cassette holder 6 is connected to the housing 1 by means of the cheeks 13.

The device works as follows.

Pre-typed characters

4 in the right quantity, in cassette 5, set into the cassette holder

6. If you need fewer characters, extra slots in the cassette.

5 are filled with mole rats, and the number of rods is always CONSTANT;

Compressed air is supplied to cavity A through port B, and acceleration of piston rod 2 and rods 3 is performed.

Pass the path L, which is shorter than the distance L, (rod-piston stroke). The rods 3 reach the signs 4, yanos t hit, and the energy of the piston-piston 2 through the elastic gasket 7 is additionally transmitted to the rods 3, then the piston rod 2 and the rods 3 stop . When struck, each bar 3 transfers its kinetic energy supply to the corresponding mark 4., which move independently of each other until it touches the surface of the end face of the workpiece 14. as a result of the movement of the signs of 4 in the cartridge 5 more than the radii of curvature of the end face of the workpiece, each sign 4 reaches the surface of the end of the workpiece and gives

clear imprint. The depth of the stamp imprint depends on the speed and weight of the rod-piston 2 and rods 3.

When stamping the next forging, air is constantly supplied to the cavity

8 through the opening G, and the piston rod 2 returns to its original position. In doing so, I interact with the protrusions

9 bar 3, piston rod 2 returns bar 3 to its original position.

The proposed design allows for a clear imprint on the end face of the forging, regardless of the curvature of its surface with minimal time loss.
