28-63 OPTIMIZAREA FABRICAȚIEI PĂRȚILOR ACTIVE ȘI ELEMENTELOR DE GHIDARE ALE ȘTANȚELOR ȘI MATRIȚELOR

OPTIMIZING PRODUCTION WORK AND GUIDING
ELEMENTS OF DIES AND MOLDS
This paper analyses the behaviour of the active parts and guidance elements of dies and moulds in the complex production process.
Analysis concerns the duration of use, number of uses without regrinding in different lubrications conditions.
Keywords: punching moulds, active part, guiding elements, number of uses
Cuvinte cheie: ștanțe-matrițe, părți active, elemente ghidare, număr de utilizări

25-73 EVALUAREA TEORETICĂ A PERFORMANȚELOR UNEI BARIERE DE SIGURANȚĂ RUTIERĂ

THEORETICAL PERFORMANCE EVALUATION
OF A TRAFFIC SAFETY BARRIER
By definition, the railing is a wall or a railing of little height which serves
to delimit the edge of a road, a bridge, aimed at stopping vehicles and
restoration mainly on the carriageway, pedestrians and conveyance of other
road users. Protective guardrail road safety ensures good road contact because
a vehicle deforms elastically, annihilating shock.
Keywords: enclosures, endurance, steel, deformation, protection
