Abstract

Zotrvačné hmoty u klukového lisu sú podlá uvedeného vynálezu vyvážené protizávažím (6) s priamočiarym vertikálnym pohybom, ktoré je poháňané od kluky (11) klukového hriadela (4) pootočenéj voči hlavným klukám (9) a (10) o 180° cez medzičlen (5) horizontálně posuvný v protizávaží (6).The inertial masses of the crank press are, according to the invention, balanced by a counterweight (6) with a rectilinear vertical movement, which is driven by a crank (11) of the crankshaft (4) rotated by 180° relative to the main cranks (9) and (10) through an intermediate member (5) horizontally movable in the counterweight (6).

Description

Vynález sa týká zariadenia pre vyváženie zotrvačných hmot u hlukového, respektive výstredníkového lisu.The invention relates to a device for balancing inertia masses in a noise or eccentric press, respectively.

Při zvyšovaní počtu zdvihov u klukových lisov dochádza k nepriaznivým účinkom zotrvačných hmot. Eliminácia horlzontálnych i vertikálnych zotrvačných sil sa stává nevyhnutnosťou. Doposial' známe prevedenia riešia tento problém buď protizávažím upevněným excentricky na kíukovom hriadeli s excentricitou pootočenou voči excentricitám hlavných kiúk o 180°, čo však nerieši účinky vertikálně sa pohybujúcich hmot, buď protizávažím, ktorého pohon je odvodený od kluky kiukového hriadeia pootočenej o 180° voči hlavným kiukám cez vlastnú ojnicu. Nevýhodou tohoto riešenia je zvačšená výška lisu, čo nepriaznivo vplýva na jeho stabilitu a vyžaduje si presnejšie a tým i nákladnejšie vyvažovanie zotrvačných hmůt.As the number of strokes of crank presses increases, the inertial masses are adversely affected. Elimination of horizontal and vertical inertia forces becomes a necessity. Previously known embodiments solve this problem either by a counterweight mounted eccentrically on the crankshaft with an eccentricity rotated by 180 ° relative to the eccentricities of the main balls, but this does not solve the effects of vertically moving masses, either by a counterweight the main kiukas through their own connecting rod. The disadvantage of this solution is the increased height of the press, which adversely affects its stability and requires a more accurate and thus more expensive balancing of the inertia masses.

Podstatou vynálezu je, že zotrvačné hrrioty u kiukového lisu sú vyvážené protizávažím s vertikálnym priamočiarym pohybom, ktoré je pohádané od kíuky kiukového hriadeia pootočenej voči hlavným kiukám o 180° cez medzičlen horizontálně posuvný v protizávaží (tzv. škótska ojnica). Pri tomto spésobe nie je potřebné zváčšovať výšku lisu, čím sa spolu s elimináciou ako horizontálnych, tak vertikálnych zotrvačných sil zvýši jeho stabilita a zabráni sa zbytočnému nárastu jeho hmotnosti. Ďalšou výhodou tohoto riešenia je, že hmota protizávažia sa nepripočítava k brzděným hmotám a nezvyšuje tak požiadavky na velkost potřebného brzdného momentu brzdy lisu.The essence of the invention is that the inertia tines in the kiuko press are balanced by a counterbalance with a vertical rectilinear movement, which is thrown from the crankshaft crank rotated 180 ° to the main kiukes through a horizontally displaceable counterweight (so-called Scottish connecting rod). In this process, it is not necessary to increase the height of the press, which, together with the elimination of both horizontal and vertical inertia forces, increases its stability and prevents unnecessary weight gain. Another advantage of this solution is that the weight of the counterweight is not added to the braked materials and thus does not increase the requirements for the required braking torque of the press brake.

Na výkrese je na obr. 1 příklad inštalácie zariadenia pre vyváženie zotrvačných hmot pódia tohoto vynálezu u dvojbodového kiukového lisu a na obr. 2 je rez priečnikom lisu v rovině protizávažia.In the drawing, FIG. 1 shows an installation of a device for balancing inertia masses according to the invention in a two-point kiuk press, and FIG. 2 is a cross-sectional view of the cross-member of the press in the plane of the counterweight.

Baran 1 lisu je poháňaný od kiukového hriadeia 4 cez ojnice 2 a 8. Protizávažie 6 sa pohybuje priamočiaro vo vedeniach 7 a 12. Pohádané je od kluky 11 kiukového hriadeia 4, ktorá sa otáča v medzičlene 5. Medzičlen 5 je uložený v protizávaží 6 s možnosťou horizontálneho posuvu. Excentricita kluky 11 je přitom pootočená voči exentricitám kl'úk 9 a 10 o 180°.The press ram 1 is driven from the kiukoshaft 4 through the connecting rods 2 and 8. The counterweight 6 moves in a straight line in the guides 7 and 12. It is taught by the boy 11 of the kiukoshaft 4 which rotates in the intermediate 5. horizontal shift option. The eccentricity of the yoke 11 is rotated by 180 [deg.] Relative to the eccentricities of the keys 9 and 10.
