Description

Invenția se referă la un mecanism pentru reglarea mărimii cursei (amplitudinii) realizate de arcurile din cutiile cu arcuri ale vibroizolației ciocanelor din secțiile de forjare.The invention relates to a mechanism for adjusting the size of the stroke (amplitude) made by the springs in the spring boxes of the hammer vibration insulation in the forging sections.

Este cunoscut că ciocanele de forjat lucrează cu șocuri produse de berbecul 1 al acestora, /fig.l/ care, se transmit blocului de fundație 2 și mai departe sistemului de vibroizolație 3. Vibroizolația consumă o bună parte din energia, care îi este transmisă în momentul loviturii berbecului ciocanului, având și scopul diminuării amplitudinii mișcării oscilatorii a întregului ansamblu (ciocan, fundație), cu scopul protejării oamenilor și obiectelor din preajma ciocanelor, clădirilor, etc.It is known that the forging hammers work with shocks produced by their ram 1, /fig.l/, which is transmitted to the foundation block 2 and further to the vibration insulation system 3. The vibration insulation consumes a large part of the energy, which is transmitted to it in the moment of the hammer ram's stroke, also aimed at reducing the amplitude of the oscillatory movement of the whole ensemble (hammer, foundation), in order to protect people and objects around hammers, buildings, etc.

Vibroizolațiile ciocanelor utilizate în secțiile de forje sunt realizate, în multe cazuri, din arcuri metalice. Acestea de regulă sunt amplasate sub blocul de fundații. Diminuarea efectelor vibrațiilor generate de ciocane se realizează prin modificarea săgeții arcurilor. Aceasta se face prin rotirea șuruburilor 5, , respectiv plăcile 7 montate în cutiile de arcuri 6 și 8 ca in fig 2. Această operație, de regulă, se face manual, obligând pe cel care face reglarea să coboare în cuva 4, / fig I / a fundației ceea ce face operația incomodă și nesigură sub aspectul protecției omului. în plus cuva 4 trebuie să aibă spații speciale suplimentare pentru accesul omului,fiind mai scumpaThe vibration insulations of the hammers used in the forging sections are, in many cases, made of metal springs. These are usually located under the foundation block. The effects of vibrations generated by hammers are diminished by changing the spring of the spring. This is done by rotating the screws 5, respectively the plates 7 mounted in the boxes of springs 6 and 8 as in Fig. 2. This operation is usually done manually, forcing the adjuster to descend into the bowl 4, / fig I / of the foundation which makes the operation uncomfortable and uncertain in terms of human protection. in addition tank 4 must have additional special spaces for human access, being more expensive

Operația de reglare-/ rotire/ a șuruburilor 5 se face în funcție de intensitatea loviturilor berbecului / energia de lovire/ ceea ce implică intervenția a omului care face reglarea, cu frecvența mare.The operation of adjusting / turning / of the screws 5 is done according to the intensity of the ram's blows / the energy of the hit / which implies the intervention of the man who makes the adjustment, with high frequency.

Conform fig 3 rotirea șurubului, 5 / fig 2/, se realizează cu un mecanism care în esență face rotirea lui, directă, cu ajutorul unui mecanism constituit din pinionul solidar cu capul șurubului 5 și cremaliera 9 montate ca în fig. 3. Acționarea cremalierei, ghidate corespunzător, se face cu un motor hidraulic liniar 10, de fapt un cilindru hidraulic. Transmiterea fluidului pentru acționarea cilindrului hidraulic 10, la parametrii funcționaliAccording to fig. 3 the rotation of the screw, 5 / fig. 2 /, is realized with a mechanism that essentially makes its rotation, direct, by means of a mechanism consisting of the pinion integral with the head of the screw 5 and the rack 9 mounted as in fig. 3. The actuator of the rack, properly guided, is made with a linear hydraulic motor 10, in fact a hydraulic cylinder. Transmission of the fluid for actuating the hydraulic cylinder 10, at the functional parameters

necesari, se face cu ajutorul unui grup hidraulic montat lângă ciocan /la suprafață., prevăzut cu un sistem care comandă corespunzător, mărimea amplitudinii mișcării oscilatorii,necessary, it is done with the help of a hydraulic unit mounted near the hammer / surface, provided with a system that controls the magnitude of the amplitude of the oscillatory movement,

Reglarea șuruburilor se face în funcție de energia loviturii, în prealabil, dar posibil și la fiecare categorie de lovituri de aceeași energie.The adjustment of the screws is done according to the energy of the blow, previously, but also possible to each category of blows of the same energy.
