Abstract

Pevná náražka je určená pre žastavenie tyčí na konci dopravníkov. ; Pevná náražka má pre zmenšenie deformácie pryžovej pružiny kyvnú páku uloženú čapom v ráme vykloněná od zvislej roviny o uhol a v rozsahu 0° až 20° smerom proti pohybu tyče. Pre váčsie pruženie je kyvná páka opatřená druhou pryžovou pružinou protifahle proti pevnej pryžovej pružině umiestnenej na ráme.The fixed stop is designed for adjusting the bars at the end of the conveyors. ; To reduce the deformation of the rubber spring, the fixed stop has a swing lever mounted on a pin in the frame, tilted from the vertical plane by an angle and in the range of 0° to 20° in the direction opposite to the movement of the bar. For greater springing, the swing lever is equipped with a second rubber spring opposite to the fixed rubber spring located on the frame.

Description

Vynález sa týká pevnej pryžovej nárazky kovových i nekovových tyčí používajúca sa na konci dopravníkov v hutných prevádzkach, zvlášť pre váčšie rýchlosti tyčí. [BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a solid rubber bump of metal and non-metal rods used at the end of conveyors in metallurgical plants, especially for higher rod speeds. [

Doteraz známe pevné pryžové náražky používá- I jú pryžovú pružinu upevnenú na ráme a majú j kyvnú páku v zvislej polohe. !The previously known solid rubber hubs use a rubber spring mounted on the frame and have a rocker lever in a vertical position. !

Pri náraze tyče je výkyv kyvnej páky do jednej ; strany a deformácia pružiny je jednostranná. Použitie len jednej pružiny znamená malú pružiacu dráhu, čo je nevýhodné pri požiadavke mákkého ; pruženia.When the rod strikes, the swing of the rocker lever is one; side and spring deformation is one-sided. The use of only one spring means a small resilient path, which is disadvantageous in the demand of the soft; suspension.

Uvedené nedostatky sú odstránené pevnou pryžovou náražkou podfa vynálezu, ktorého podstatou je, že jej kyvná páka uložená čapom v ráme je od zvislej roviny vykloněná o uhol a v rozsahu 0° až 20° smerom proti pohybu tyče. Ďalším znakom je, že kyvná páka je opatřená druhou pryžovou pružinou protirahle proti pevnej pryžovej pružině umiestnenej na ráme.The above drawbacks are eliminated by the solid rubber sleeve according to the invention, the principle of which is that the pivot lever mounted in the frame is inclined from the vertical plane by an angle α in the range of 0 ° to 20 ° towards the rod movement. Another feature is that the rocker lever is provided with a second rubber spring opposed to the rigid rubber spring mounted on the frame.

Pevná pryžová náražka podlá vynálezu zmenšuje bočnú deformáciu pružiny a tým zvyšuje jej životnost. V případe použitia dvoch pružin oproti sebe dosiahne sa mákkého pruženia.The rigid rubber sleeve of the invention reduces the lateral deformation of the spring and thereby increases its life. In the case of using two springs against each other, a soft spring is achieved.

Claims

A fixed bumper consisting of a rocker lever i and at least one rubber spring mounted on a frame, characterized in that its rocker lever (3) 'supported by a pin (2) in the frame (1) is inclined by an angle (α) from vertical 0 ° to 20 ° against the bar movement. .

The attached drawing shows an example of a fixed rubber buffer used for punching metal bars at the end of the conveyor, where in FIG. 1 is a schematic front view of a fixed buffer with one rubber spring, and FIG. 2 with two rubber springs. For clarity, a thin line drawn conveyor and a bar. The direction of movement of the bar is indicated by an arrow.

The rigid rubber buffer with one rubber spring (in Fig. 1) consists of a frame 1 on the pivot 2 with a rocking lever 3 so that it is inclined from an vertical plane by an angle and in a range of 0 ° to 20 ° 7. The choice of the tilt angle size depends on the impact energy of the bar. The rocker lever 3 is supported by a rubber spring. 4 with pad 5.

A fixed rubber spring with two springs (in FIG. 2) additionally has a rubber spring 8 mounted on the pivot lever 3 opposite the rubber spring 4 fixed to the frame 1.

INVENTION!

Fixed bumper according to claim 1, characterized in that the rocker lever (3) is provided with a second rubber spring (8) opposite to the fixed rubber spring (4) located on the frame (1).
