Description

Przedmiotem wynalazku jest tlocznik przeznaczony szczególnie do ksztaltowania wytloczek cylindrycznych z prostokatnych wykrojów.The subject of the invention is a die intended especially for shaping a die cylindrical from rectangular blanks.

Dotychczas ksztaltowanie wytloczek z wykrojów prostokatnych dokonywane jest za pomoca matryc ksztaltowych o zmiennym profilu krawedzi ciagowej. Zmienny profil krawedzi ciagowej, trudny technologicznie do realizacji, umozliwia bardziej ekonomiczne wykorzystanie materialu, z którego jest ksztaltowana wytloczka.So far, shaping of the stampings from rectangular blanks is performed with the use of dies shaped, with a variable profile of the pulling edge. Variable draw edge profile, technologically difficult for implementation, it allows a more economical use of the material from which the mold is formed.

Takze celem bardziej ekonomicznego wykorzystania materialu sa stosowane dociskacze zlozone z dwóch pierscieni, które zapewniaja zmienna sile docisku w czasie ksztaltowania wytloczki. Konstrukcja takich dociskaczy jest skomplikowana, zas technologia pracochlonna.The clamps composed of two are also used for more economic use of the material rings that provide variable clamping force as the mold is formed. The construction of such clamps is complicated and the technology is labor-intensive.

Tlocznik wedlug wynalazku, wyposazony w tuleje ciagowa, stempel i pierscien dociskowy, posiada w pierscieniu dociskowym umieszczone, suwliwie wzdluz jego osi, wkladki nieco wyzsze niz wysokosc pierscienia dociskowego, przy czym wkladki sa podparte srubowa sprezyna, za posrednictwem dwóch tulei i umieszczonych miedzy nimi kolków, wsparta na czole nakretki sruby zlaczonej z korpusem, zas pierscien dociskowy jest podparty druga srubowa sprezyna, za posrednictwem kolków i tulei, wsparta na czole nakretki, nakreconej na nakretke, na której jest wsparta sprezyna podpierajaca wkladki.The die according to the invention, equipped with a pull sleeve, a punch and a pressure ring, has in the clamping ring there are inserts slightly higher than the height, slid along its axis a pressure ring, the inserts being supported by a screw spring via two bushings and the studs placed between them, a screw attached to the body supported on the forehead, and the ring the compression spring is supported by a second screw spring, via pins and a sleeve, supported on the face of the nut, screwed on a nut, on which is supported a spring that supports the inserts.

Podczas ksztaltowania wytloczki w miejscach tworzenia sie zaglebien material jest dociskany z wieksza sila przez wkladki niz w pozostalych miejscach, w których dociskany jest przez pierscien dociskowy. Umozliwia to zróznicowane napiecie sprezyn podpierajacych wkladki i pierscien dociskowy, dzieki czemu uzyskane zostaje zwiekszenie wysokosci wytloczki oraz wyrównanie scian na obwodzie.When shaping the extrudate, the material is pressed more strongly at the basins power through the inserts than in the other places where it is pressed by the clamping ring. It makes it possible is the different tension of the springs supporting the inserts and the pressure ring, thanks to which increasing the height of the molding and aligning the walls around the perimeter.

Przedmiot wynalazku w przykladzie wykonania zostal uwidoczniony na rysunku, na którym fig. 1 przedstawia tlocznik w przekroju wzdluznym, fig. 2 — pierscien dociskowy w widoku z,góry, fig. 3 — pierscien dociskowy w przekroju wzdluz linii AA na fig. 2, fig. 4- wytloczke w widoku z dolu i fig. 5 wytloczke w przekroju wzdluz linii B-B na fig. 4.The subject of the invention in an exemplary embodiment has been shown in the drawing in which Fig. 1 shows the die in longitudinal section, fig. 2 - clamping ring in top view, fig. 3 - ring press section in a section along line AA in Fig. 2, Fig. 4-, the stamping piece in a bottom view, and Fig. 5, in section along line B-B in Fig. 4.

Tlocznik wyposazony w-tuleje ciagowa 1 posiada w swym korpusie 2 umieszczony stempel 3, na którym jest osadzony pierscien dociskowy 4. Pierscien dociskowy 4 jest wyposazony we wkladki 5 nieco wyzsze niz2 93188 pierscien 4. Wkladki 5 sa podparte za posrednictwem tulei 6, kolków 7 i tu&i 8, sprezyna srubowa 9 wsparta na czole nakretki 10 sruby 11 zlaczonej z korpusem 2, Pierscien dociskowy 4 jest podparty, za posrednictwem kolków 12 i tulei 13, srubowa sprezyna 14 wsparta na czole nakretki 15 nakreconej na nakretke 10.A die equipped with a drawing sleeve 1 has a stamp 3 in its body 2, on which the pressure ring 4 is fitted. The pressure ring 4 is fitted with inserts 5 slightly higher than 2 93188 ring 4. Inserts 5 are supported by bushing 6, pins 7 and here & i 8, coil spring 9 supported by the face of the nut 10 with the bolt 11 attached to the body 2, the clamping ring 4 is supported by of pins 12 and bushing 13, a screw spring 14 supported on the face of a nut 15 screwed onto a nut 10.

W czasie ksztaltowania wytloczki sily oddzialujace na material przez pierscien 4 i wkladki 5 sa rózne, co spowodowane jest róinym napieciem sprezyn 14 \9. Pc napieciu zwieksza sila sprezyny 9 uzyskuje sie korzystnie wieksza sile docisku w miejscu tworzenia sie zaglebien w materiale, a to pozwala na uzyskanie zwiekszonej wysokosci wytloczki oraz wyrównania scian na obwodzie. Napiecie sprezyn regulowane jest pokreceniem nakretek 10 i 15.During the forming of the extrudate, the forces affecting the material through the ring 4 and the inserts 5 are different, which is caused by a different spring tension 14 \ 9. Pc tension increases the strength of the spring 9 is obtained preferably greater pressure force at the place where the depths are formed in the material, and this allows to obtain increased height of the molding and the alignment of the walls around the perimeter. The tension of the springs is adjustable by turning the nuts 10 and 15.
