Description

Strains FOR deep 1.1 g LCD 11 per one stroke of the polauna press, with il ;; iva11, 1.m punch for mechanical stretching, with nesting nodach 1) fluids for direct hydraulic action on the workpiece, known. These and; known The ngtampes have the disadvantage that in the gynehs in the nrones it worked with the thinning of the bottom of the preform, the walls of the last one were subjected to braking). c)) the result of which is often the origin of a gap.

In the proposed stamp, this disadvantage is eliminated by the fact that the nuanson wavelength pz, next to each other, jiaoOTy; 1; T1 of the forest parts, of which the first part is 1; ontures, (corresponding to; the basis of the product surface, and the inner part is made in order so that between it and 3aroTOBKoii there is a space for transferring the working medium, which forms the bottom of the workpiece in the matrix.

The proposed strain is shown in the drawing in section.

The punch of the stamp is made of sliding telescopic parts (1) and (2). The outer part (2) of the punch has contours (3) corresponding to the lateral surface of the finished product (4). The top (5) of the inner part (1) of the punch is made prefixed so that between it and the workpiece (4) there is a space (6) for supplying the working medium, forming the bottom of the workpiece in the matrix (7).

During the working cycle of the die, the die (7) draws the workpiece to the part (2) of the punch from under the pressure

(eight). No effort can be made to create liquid .., liquid liquid, 11 thuy; 1Hp but Ti) ()) under the piston (10) and with a heap of 11) through the rolling pin (11).

 Further, the process of the matrix (7) is performed on the part (1) of the nowaneon from the node of the part (2); the latter is iodine by the action of a liquid, the postunit to the pipe (12) to | rostranst1 o (13). At the end of the turn, 1; la1 an (14) n lgdkpst) l :, 1G) OST |) anastl a (13) pg (oTBeiJCiiiii (15) enters r, the space (G) n (|) bottom of the contour of the matrix (7).

The adjustment of the clearances I; 1; the duo mat (7) and nrzhimpm (8), as well as part 1 10 (2) of nuaxon, is realized by boltamn (Ki).

1Ptamn for deep wiring; 1; 11. for example, headlamp housings, in one stroke of a ram, a press, using a punch for mechanical stretching, followed by feeding the working medium for direct hydraulic action on the workpiece, which is heavy; and by the fact that, in order to prevent the rupture of the workpiece due to braking of its walls with thinning of the bottom, the technique was taken from hereditarily concurrently with the sliding telescopic parts, of which the outer part has 1; , and the top of the inner part is made nitrious, so that the melau and the workpiece will form a space for supplying the working medium: the medium intended to mold the bottom of the workpiece into matrices (..
