Description

Riešenie sa týká zariadenia, ktoré tlmí spatný ráz naklápaných brzdných lamiel brzdy mechanického lisu. To sa dosiahne tým, že výčnělky brzdných lamiel sú podopreté cez opierku, tlmiace pružiny, podložku a maticu o třň prechádzajúci pomedzi brzdné lamely a pevne uchytený o rám stroja.The present invention relates to a device which attenuates the backlash of the pivoted brake discs of a mechanical press brake. This is achieved by supporting the protrusions of the brake discs through the support, the damping springs, the washer and the nut on the mandrel extending between the brake discs and firmly attached to the machine frame.

Predmetom vynálezu je zariadenie na tlmenie spatného rázu naklápaných brzdných lamiel brzdy mechanického lisu.SUMMARY OF THE INVENTION The present invention relates to a device for attenuating the back impact of the pivoted brake discs of a mechanical press brake. Funkcia brzd mechanických lisov je z bezpečnostných dóvodov kontrolovaná pri každom zabrzdění, čo sa prevádza snímáním naklopenia brzdných lamiel. Toto naklopeniei lamiel je vyvodené brzdným momentom, ktorý je zachytávaný stláčajúcimi sa pružinami. Tieto sa po odbrzdení brzdy uvotnia a vymrštia obidve brzdné lamely opačným smerom, čo spůsobuje rázové namáhanie a poškodzovanie častí brzdy, ako aj zvýšenu hlučnost celého uzla, nakolko spatný ráz brzdy je nie v súčasnosti žiadnym spósobom eliminovaný.For safety reasons, the brake press function of the mechanical presses is checked each time the brake is applied, which is done by detecting the tilt of the brake discs. This tilting of the slats is due to the braking torque which is absorbed by the compressing springs. After the brake is released, both brake plates are thrown and ejected in the opposite direction, causing shock stresses and damaging the brake parts, as well as increased noise of the whole node, since the bad brake impact is currently not eliminated in any way. Uvedené nevýhody odstraňuje riešenie podta vynálezu, ktorého podstata spočívá v tom, že spatný ráz vyvolaný pružinami zachytávajúcimi brzdný moment brzdných lamiel je prenášaný prostredníctvom opierky pod výčnelkami brzdných lamiel na tlmiace pružiny podopreté podložkou a maticou, pričom celý tento reťazec je nasunutý na třň prechádzajúci pomedzi výčnělky brzdných lamiel a uchytený o rám stroja.The above-mentioned disadvantages are eliminated by the solution according to the invention, characterized in that the backlash caused by the springs capturing the braking torque of the brake discs is transmitted by a support under the brake disc protrusions to the damping springs supported by the washer and nut. brake plates and attached to the machine frame. Tým dochádza ku ktudnému chodu celého zariadenia, predíženiu životnosti celého uzla a zníženiu jeho hlučnosti.This leads to the operation of the whole device, extending the life of the whole node and reducing its noise. Příklad vyhotovenia zariadenia podía vynálezu je znázorněný na obrázkoch.An example of an embodiment of the device according to the invention is shown in the figures. Brzdný moment MB vyvodený přitlačením brzdných lamiel 1, 2 na nezobrazená rotujúcu lamelu sa prenáša cez výčnělky brzdných lamiel 1 a 2 cez opierku 3 na pružiny pre zachytenie brzdného momentu 4 nasunuté na třň 5 a opreté o rám stroja 6. Po odbrzdení brzdy sú brzdné lamely 1 a 2 účinkom predpátia pružin pre zachytenie brzdného momentu 4 vymrštěné v smere brzdného momentu Ms a cez opierku 7 narazia na tlmiace pružiny 8, ktoré sú vedené třňom 5. Tlmiace pružiny 8 prenášajú zataženie cez podložku 9 a maticu 10 na třň 5 prechádzajúci pomedzi výčnělky brzdných lamiel 1 a 2 a uchytený o rám stroja 6.The braking torque M B exerted by pressing the brake discs 1, 2 onto the rotating disc not shown is transmitted through the protrusions of the brake discs 1 and 2 through the spring support 3 for braking torque 4 pushed onto the spindle 5 and supported on the machine frame. the blades 1 and 2, due to the biasing of the braking torque springs 4, ejected in the direction of the braking torque M s and impact the damping springs 8 which are guided by the thrust 5 through the backrest 7. between the protrusions of the brake plates 1 and 2 and attached to the machine frame 6. PREDMETSUBJECT Zariadenie na tlmenie spatného rázu naklápaných brzdných lamiel brzdy mechanického lisu, pozostávajúce z třňa, prechádzajúceho pomedzi výčnělky brzdných lamiel a uchýleného na straně pósobenia brzdného momentu o rám stroja, pričom na tejto straně třňa je naň nasunutá opierka a pružiny pre zachytenie brzdného momentu, opierajúce sa o rám stroja, vyznačené tým, že na opačnéj straně třňa (5) je naň postupné smerom od výčnelkov brzdných lamiel (1, 2) nasunutá opierka (7), tlmiace pružiny (8) a podložka (9), podopretá prestavitelnou maticou (10).A device for damping the kickback of the pivoted brake discs of a mechanical press brake, comprising a spindle extending between the brake disc protrusion and retained on the braking torque application side of the machine frame, with the support and springs retaining the braking torque. machine frame, characterized in that on the opposite side of the mandrel (5) a support (7), damping springs (8) and washer (9) supported by an adjustable nut (10) ).
