Stamp for radial extrusion
(57) Abstract:The invention relates to the processing of metals by pressure, in particular for landing heads of different shapes on the rod blanks. Stamp for radial extrusion comprises a frame made with grooves clip-matrix and the punch. In the grooves of the bed posted a guide that is fixed to the holder-matrix, which is installed with the possibility of a managed move along its axis. Dragging is carried out by means of a controlled drive connected with the yoke-matrix by means of screw and worm gear. The result is the enhancement of technological capabilities by obtaining heads of different shapes on the rods by the method of radial extrusion, and eases Assembly and disassembly of the stamp. 4 Il. The invention relates to the processing of metals by pressure, in particular for landing heads of different shapes on rod blanks.Famous stamp for the manufacture of parts with flanges containing a punch and die with a freely mounted inside the annular insert is provided with a mechanism for moving the annular liner along the axis of the matrix in the process of shaping (SU one in him landing sections of porzucek, the lower body placed in it, with the possibility of translational movement along the axis of the landing bottom landing sections of porzucek, adjustable limit stops, the actuator is opened, the upper sections of porzucek and the opening mechanism of the lower sections of porzucek associated with the ejector press the V-element to clamp and counter movement of the upper and lower sections of porzucek, while the lower landing section of porzucek provided with an additional adjustable stops and removable rods, with stops mounted on the rods, and the rods attached to polosko, the opening mechanism of the lower porzucek made in the form of a system of levers and forks installed in an end-to-end longitudinal grooves, made in the lower case stamp (SU 1792782 A1, 07.02.1993, 21 J 5/08).The closest in technical essence and the achieved effect is known stamp for radial extrusion, consisting of a frame, clip-matrix and punch (SU 125726, 03.03.1960, 21 J 5/08). The stamp is used to retrieve the heads on the rod blanks.The disadvantage of this stamp is the impossibility of obtaining heads of different shapes and associated low technological capabilities.The task of izaberete the house managed radial extrusion, as well as facilitating the Assembly and disassembly of the stamp.For this stamp for radial extrusion containing a frame, clip-matrix and the punch, is supplied rail attached to the clip-matrix, the bed is done with grooves for placement mentioned guide clip-matrix, which is installed with the possibility of a managed move along its axis by means of an actuator connected with the yoke-matrix by means of screw and worm gear.In Fig.1 depicts a stamp for radial extrusion;
in Fig.2 - bed in the incision;
in Fig.3 is a view along a-a frame;
in Fig.4 is a view along b-B of the bed.The stamp for the implementation of radial extrusion consists of a plate 1, a bottom 2, attached to the plate 1, on which the base 3 attached to the bottom 2 and to which is attached an isothermal bath 4, the punch 5, removable head 6, rod 7, clip-matrix 8, the guide 9 is fixed by means of keys 10 and nuts 11, the stops 12 and 13 are fastened together, the worm gear 14, 15. Clip-matrix 8 and the stop 12 is formed between a screw pair. Replaceable head 6 mounted on the yoke-matrix 8 by threaded connection. In frame 3 made grooves 1 2 clip-matrix 8, lowered until it touches the bottom 2. Next, set the move clip-matrix for the formation of a gap for the flow of metal through action on the worm gear, delivered through software-controlled motor. Worm gear acts on the clip-matrix 8 via a screw pair. To avoid rotation of the cage-matrix 8 around its axis clip-matrix 8 is connected with the guide rail 9, moving along the slots 16 in the frame 3. After setting the travel cage-matrix 8 press software provides pressure on the plug 5 via the shaft 7. After reaching a certain degree of extrusion of the newly implemented software job gap by moving the clip-matrix 8 and the extrusion is carried out again and so on Stamp for radial extrusion containing a frame, clip-matrix and the punch, characterized in that it has a rail attached to the clip-matrix, the bed is made with grooves for placement mentioned guide clip-matrix, which is installed with the possibility of a managed move along its axis by means of an actuator connected with the yoke-matrix by means of screw and worm gear.

FIELD: metal working.
SUBSTANCE: hard alloy matrix has casing, bushing pressed in the case and hard alloy insertion. Bushing has multifaced hole. Hard alloy insertion is composed by several sections made in form of trapezoidal-section prisms which have cut angles at their non-working edges. Number of sections corresponds to number of faces of item to be headed. Cuts of angles are made symmetrically to faces of working edge. Slits are made in several places of multifaced hole bushing at the ponts where faces cross each other.
EFFECT: improved resistance of matrix; simplified assembly.
