Tehnologicitatea sau conditii tehnologice indeplinite de piesele decupate:

Este necesar, ca la intocmirea tehnologiei de executie, sa se tina cont de urmatoarele aspecte,

importante pentru obtinerea unor piese prelucrate de buna calitate:
- Distanta minima dintre doua orificii perforate
- Distanta dintre marginea orificiului si cea a piesei
Avand in vedere conditiile de rezistenta ale placii active, distantele dintre orificii, sau
dintre marginea orificiului si cea a placii active, trebuie sa corespunda indicatiilor din figura
aferenta.

Razele de racordare
minime la contururile unghiulare se recomanda sa se aleaga conform indicatiilor din tabelul de
mai sus:

Rp- raza poanson;

Rpl- raza placii;
2. Stabilirea formei si dimensiunea semifabricatului

Avand in vedere forma si dimensiunile piesei perforate vom alege un semifabricat dreptunghiular
cu aria egala 11884,12mm^2.
3.Analiza utilizarii eficiente a semifabricatului

Pentru economie de material, se va folosi 70% minim pentru croire ( 70% din costul piesei va fi
reprezentat de costul materialului.
Prin croirea materialului se intelege stabilirea economica a pozitiei piesei pe semifabricatul din
tabla, de obicei sub forma de foaie de tabla, banda sau fasie.
Croirea este influentata de :
-forma, dimensiunile si precizia piesei;
-duritatea si grosimea materialului.
Se va pune accent pe utilizarea economica a materialului, deoarece, in costul general, costul
materialului este cuprins intre 60%-80% din costul piesei.

Modalitati de croire a materialului in functie de forma piesei:

Croire in functie de precizia materialelor:
B=100,71+2*2.5+0.4= 106,11 mm;
A=106,11+1.25=107,36 mm;
p= d+a=100,71+2= 102,71 mm;
npf=L/p=2500:102,71=24,34 piese
Kf=(Ap*npf)/(B*L)
Kf= 11884,12*24,34/106,11*2500= 1,09%

Notatii:
B- latimea nominala a fasiei;
D- dimensiunea maxima a piesei pe directia latimii fasiei;
b- dimensiunea minima a puntitei laterale ;
TB – toleranta la latimea fasiei;
A-Distanta dintre ghidajele stantei
j- distanta dintre ghidaje si fasie ( jocul) – se ia intre 1…1.5 mm, de preferat jumatate ;
p- pasul
d- dimensiunea piesei pe directia lungimii fasiei ( sau de avans)
La croirea pe un singur rand cand stanta este prevazuta cu dispozitiv de strangere a
semifabricatului folosim formula 1
Pentru formula kf ( calculul coeficientului de utilizare a materialului )
Ap- aria piesei = A0 sau a semif individual ce urmeaza a fi decupat
Npf- numarul de piese dintr-o fasie

Numarul fasiilor dintr-o foaie:

nf= l/B
nf= 2000/106,11= 18,84 – aprox 19 fasii;

Numarul pieselor pe o foaie de tabla:

npt= npf*nf
npt= 24,34*18,84= 459 piese ;
Numarul foilor de tabla necesare:
nr foi= nr.serie fabricatie/npt;
nr foi= 100.000/459 + 20 = 239 foi ( +10 foi marja);

Calcului pretului:
Pret foaie=80 lei
Pret total=239*80=19120lei

5.Stabilirea variantelor posibile de prelucrare si alegerea variantei

optime din punct de vedere economic:
Pentru piesa noastra avem urmatoarele variante de prelucrare:
1.Operatia de perforare a gaurilor
2.Operatia de decupare a formei piesei
3.Operatia de indoire a mijlocului piesei
4. Operatia de indoire a marginilor piesei
