The invention relates to the thresholds of metallurgy, in particular, to devices for extruding articles from powder.

The aim of the invention is to expand the technological capabilities of the device by ensuring the production of products with grooves.

The drawing shows a diagram of the proposed device.

The device consists of a chamber 1 for a powder formed by a matrix 2 with extrusion point 3 and a punch 4, made glass-shaped with 15

a side wall 5 on which protrusions 6 are made with conical surfaces 7, a press stamp 8 is fixed on the bottom of the punch 8. Under point 3 there are grooves 9 in which 20 characters 10 are placed with surfaces 11 corresponding to surfaces 7.

The device works as follows.

In the chamber 1 is placed the workpiece 25 from the powder (not shown).

When moving down, the punch 4 presses 8 through the point 3 of the matrix 2, while the wall 5 of the cup also moves. When exposed to a conical surface 7 of the protrusion 6 on the surface 11 of the sign 10, the latter, moving πό to the hole 9,

squeezes the groove in the product. With the passage of the protrusion 6 and the release of the sign 10, the latter under the influence of the extruded metal returns to its original position. The product is extruded without a groove. When the second protrusion 6 is pressed on the sign 10, the sign is re-pressed into the metal and new slots are formed. The placement of the projections 6 can be adjusted. the length of the grooves in the product.

Claims (1)

Claim A device for extruding products from a powder containing a die with extrusion point and a punch, characterized in that, in order to expand its technological capabilities by providing products with grooves, it is provided with signs, the punch is made in the form of a glass with a press fixed on its bottom. stamp, the inner diameter of the glass exceeds the outer diameter of the matrix, and the inner walls of the glass are made protrusions with conical surfaces, while the matrix is made with slopes inclined to its longitudinal axis, exit and signs are placed in the slots.
