Abstract
Zotrvačné hmoty u klukového lisu sú vyvážené nielen protišmykadlom poháňaným v priamom vedení od vyvažovacej kluky pootočenej voči hlavným klukám o 180° cez ojnicu, ale zároveň aj protizávažiami uloženými na klukovom hriadeli otočné okolo jeho osi otáčania a natáčenými pomocou unášacieho čapu uloženého neposuvne v ojnici s umožněním jeho radiálneho posuvu v protizávažiach.The inertial masses of the crank press are balanced not just the anti-skid driven in direct line from balancing boy turned towards the main boys 180 ° through the connecting rod but at the same time counterweights mounted on the crankshaft rotatable about its pivot axis and pivoted by means of a driving pin stored non-sliding in the connecting rod with its radial displacement in counterweights.
Description
Vynález sa týká zariadenia na vyvážanie zotrvačných hmót u klukového lisu.The invention relates to an apparatus for balancing inertia masses in a crank press.
Pri zvyšovaní počtu zdvihov u klukových lisov dochádza k nepriaznivým účinkom vplyvom zotrvačných hmót. Doposiaí známe prevedenia riešia tento problém bud protizávažím upevněným excentricky na klukovom hriadeli s exentricitou pootočenou voči excentricitám hlavných klúk o 180°, čo však nerieši účinky vertikálně sa pohybujúcich hmót, alebo protizávažím, ktorého pohon je odvodený od kluky klukového hriadela pootočenej o 180° voči hlavným klukám cez vlastnú ojnicu. Nevýhodou tohto riešenia je nevyváženost zotrvačných krútiacich momentov ojníc. Táto nepriznivo vplýva na stabilitu lisu a vynucuje si presnejšie a tým aj pracnejšie riešenie vyvažovacieho mechanizmu, ako i uloženia lisu.As the number of strokes of crank presses increases, there are adverse effects due to inertia masses. Previously known embodiments solve this problem either by a counterweight mounted eccentrically on the crankshaft with eccentricity rotated by 180 ° to the eccentricities of the main spokes, but this does not solve the effects of vertically moving masses, or by counterweight boys through my own connecting rod. The disadvantage of this solution is the unbalance of the inertia of the connecting rod torques. This adversely affects the stability of the press and necessitates a more precise and thus laborious solution of the balancing mechanism as well as of the press bearing.
Výhodou navrhovaného riešenia vyváženia zotrvačných hmót u klukových lisov pomocou protišmýkadla poháftaného cez ojnicu od vyvažovacej kluky na klukovom hriadeli lisu pootočenej voči hlavným klukám o 180° je, že cez ojnicu sú poháňané nielen posuvné ale aj otočné kmitajúce protizávažia. Tento mechanizmus umožňuje znížit zotrvačné krútiace momenty v pohone lisu.The advantage of the proposed solution of balancing inertia masses in crank presses by means of a slide slide driven through the connecting rod from the balancing jack on the crankshaft of the press rotated by 180 ° relative to the main jacks is that not only sliding but also rotating oscillating counterweights. This mechanism makes it possible to reduce the inertia torques in the press drive.
Ďalšou výhodou tohto riešenia je, že hmota protizávažia sa nepripočítava k brzděným hmotám a nezvyšuje tak požiadavky na velkost potřebného brzdného momentu brzdy lisu.Another advantage of this solution is that the mass of the counterweight is not added to the braked masses and thus does not increase the requirements for the required braking torque of the press brake.
Na výkrese je na obr. 1 příklad zariadenia pre vyvážanie zotrvačných hmót podlá tohoto vynálezu u dvojbodového klukového lisu. Na obr. 2 je rez priečnikom lisu v rovině A-A.In the drawing, FIG. 1 shows an example of a device for balancing inertia masses according to the invention in a two-point crank press. In FIG. 2 is a cross-sectional view of the press in the line A-A.
Baran 2 lisu je poháňaný od klúk 15 a 16 klukového hriadela 5 cez ojnice 3 a 4. Od kluky 17, ktorej excentricita je pootočená voči klukám 15 a 16 o 180°, je cez ojničný čap 7 poháňané protišmýkadlo j! v priamom vedení 2 a zároveň cez unášaoí čap 14 uložený neposuvne v ojnici (i sú poháňané protizávažia 12 a 13, pričom unášací čap 14 má v protizávažiach 12 a 13 možnost radiálneho posuvu. Protizávažia 12 a 13 sú pomocou puzdier 10 a 11 uložené na klukovom hriadeli 5^ otočné okolo jeho osi otáčania.The ram 2 is driven from the crankshaft keys 15 and 16 through the connecting rods 3 and 4. From the jack 17, whose eccentricity is rotated 180 ° relative to the jacks 15 and 16, the slide rod 7 is driven by the slide. in the direct guide 2 and at the same time via the driving pin 14 mounted non-movably in the connecting rod (i, counterweights 12 and 13 are driven, the driving pin 14 has a possibility of radial displacement in the counterweights 12 and 13). the shaft 5 is rotatable about its axis of rotation.
