Abstract

The fixture has screws (4) through an extension plate (3) clamping the die plate (1) around its periphery to the flange (2) of the extrusion mould chamber. Another screw (6) passes through the middle of the die plate and attaches it to a central projection from the inlet piece (5) inside the mouth of the mould chamber. The whole of the circumference of the inlet piece is in contact with the inside face of the die plate. The central and peripheral screws and edge contact with other components provide a uniform support for the die plate.

Description

Ob1asť techn i kyTechnical part

Vynález sa týka zariadenia na upevnenie matrice na komoru závitovkového lisu pri čelnom pretláčaní keramickej hmoty cez dierovanú matricu.BACKGROUND OF THE INVENTION The present invention relates to an apparatus for fastening a die to a screw press chamber in the face of a die.

DoterajSl stav technikyBACKGROUND OF THE INVENTION

Doposiaľ bola dierovaná matrica upevnená po obvode medzi prírubu komory a rám s vôľou a taktiež tak prostredníctvom skrutky k stredovému náboju. Matrica nebola pevne votknutá a pri zaťažení tlakom dochádzalo vplyvom nedokonalého votknutia k deformácii, pripadne k deštrukcii matrice.Until now, the perforated die has been fixed circumferentially between the flange of the chamber and the frame with clearance, as well as by means of a screw to the central hub. The matrix was not firmly imbedded, and under pressure loading, deformation or destruction of the matrix occurred due to imperfect impingement.

Podstata vynálezuSUMMARY OF THE INVENTION

Uvedené nedostatky do značnej miery odstraňuje zariadenie na upevnenie matrice podľa vynálezu, ktorého podstata spočíva v tom, že matrica je po obvode pevne votknutá medzi prírubu komory a rám skrutkami a stred matrice skrutkou k náboju vložky, ktorá sa obvodom opiera o vnútornú plochu matrice.These drawbacks are largely eliminated by the matrix fastening device according to the invention, characterized in that the matrix is fixedly circumferentially fixed between the flange of the chamber and the frame by screws and the center of the matrix by a bolt to the cartridge hub which rests circumferentially on the inner surface of the matrix.

Zariadenie podľa vynálezu umožňuje pevným votknutim matrice v uplnaclch plochách vytvorenie kompaktného celku, čim sa zníži nebezpečie deformácie matrice, prípadne jej deštrukcia pri zaťažení tlakom.The device according to the invention makes it possible to form a compact unit by firmly engaging the matrix in the sealing surfaces, thereby reducing the risk of deformation of the matrix or its destruction under pressure loading.

Prehľad obrázkov na výkreseOverview of the figures in the drawing

Príkladné vyhotovenie zariadenia na upevnenie matrice podľa vynálezu je znázornené na pripojenom vyobrazení, kde obr. 1 znázorňuje zariadenie na upevnenie v reze a obr. 2 pohľad z čelnej strany.An exemplary embodiment of a matrix fastening device according to the invention is shown in the accompanying drawing, wherein FIG. 1 shows a sectional fastening device and FIG. 2 is a front view.

Príklady vyhotovenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Zariadenie podľa obr. 1 pozostáva z dierovanej matrice X, ktorá je pevne votknutá po obvode medzi prírubu komory 2 a rám 3 prostredníctvom skrutiek 4. Stredom je matrica X pevne votknutá k náboju vložky 5 stredovou skrutkou 6. Vložka 5 sa svojim obvodom opiera o matricu 1_ z vnútornej strany.The device of FIG. 1 consists of a punched die X which is fixedly circumferentially fixed between the flange of the chamber 2 and the frame 3 by means of screws 4. In the middle, the die X is firmly fixed to the cartridge hub 5 by a center screw 6. .

Pevným votknutlm matrice 1. medzi rám 3 a prírubu komory 2 po obvode a pevným pritiahnutím matrice X stredom stredovou skrutkou 6 k náboju vložky 5 bez vôle, je dosiahnuté dokonalé votknutie matrice X v upínacích plochách a priaznivejší priebeh napätia v pracovnej ploche matrice X pri zaťažení t1akom.By firmly engaging the die 1 between the frame 3 and the flange of the chamber 2 circumferentially and firmly tightening the die X by the center screw 6 to the hub of the liner 5 without play, a perfect fit of the die X in the clamping surfaces is achieved. t1akom.
