Abstract

Invenția se refera la o scula de alezare-durcisare prin aschiere-roluire, pentru prelucrarea alezajelor intr-o operație combinata. Scula este formata dintr-un subansamblu de așchiere, coroborat cu unul de durcisare, si este prevăzută cu un cilindru cuprinzător (2), reglabil, avind niște suprafețe profilate, de reglare, pe care se sprijină niște role de lucru (3), coaxiale cu alte role (4), de urmărire, cuprinse de un cilindru-colivie (5), prins de corpul central (1) cu un știft radial (6) ce formează subansamblul de durcisare, coroborat cu cel de așchiere, format dintr-un cutit radial (9), deplasabil cu ajutorul unui știft filetat (10), sprijinit de un stift (11).The invention relates to a boring-hardening tool by cutting-rolling, for processing bores in a combined operation. The tool is formed from a cutting subassembly, in conjunction with one of hardening, and is provided with a cylinder comprehensive (2), adjustable, having profiled surfaces, adjustment, which is supported by working rollers (3), coaxial with other rollers (4), tracking, included by a cylinder-cage (5), caught by the central body (1) with a radial pin (6) forming the subassembly hardening, in conjunction with the cutting, formed from a radial knife (9), movable by means of a threaded pin (10), supported by a pin (11).

Description

Invenția se referă la o sculă de alezare - dnrcisare, prin așchiere - ro bure, peniru prelucrarea ulezujelor într-o operație combinată.The invention relates to a tool of boring - cutting, by cutting - ro bure, for the processing of the oilings in a combined operation.

Sint cunoscute scule dc alezare durcisare, prin așchiere - roluire, formate din cîte o tijă centrală, cuprinsă de piese tubulare, conjugate, pe care sînt prinse cuțite așchietoare conjugate cu role, toate coroborate cu elemente dc reglare.There are known tools for hardening bore, by cutting - rolling, formed of a central rod, comprised of tubular parts, conjugated, on which are cut knives conjugated with rollers, all corroborated with elements of regular adjustment.

Dezavantajele acestor scule constau în aceea că prezintă construcții cu reglabilitate redusă, capabile să execute o gomă redusă de alezaje.The disadvantages of these tools are that they have low adjustable constructions, capable of executing a reduced bore of bores.

Scula conform invenției înlătură dezavantajele menționate mai sus prin aceea că este prevăzută cu un cilindru cuprinzător reglabil avînd niște suprafețe radiale, profilate, de regalre, pe care se sprijină niște role de lucru, coaxiale cu alte role de urmărire, cuprinse de un cilindru-colivie prins de corpul central, cu un știft radial, ce formează subansamblul de durcisare, coroborat cu ccl dc așcbicre, format dintr-un cuțit radial, deplasabiî cn ajutorul unui știft filetat, sprijinit de un alt știft.The tool according to the invention removes the disadvantages mentioned above by being provided with an adjustable comprehensive cylinder having radial, profiled, regal surfaces, on which work rolls are supported, coaxial with other tracking rolls, contained by a cylinder-cage grabbed by the central body, with a radial pin, which forms the hardening subassembly, in conjunction with the dc ascbicre, formed by a radial knife, displaced by the aid of a threaded pin, supported by another pin.

Se dă, în continuare, un exemplu de realizare a invenției în legătură cu fig. 1...3, care reprezintă:The following is an example of an embodiment of the invention in connection with FIG. 1 ... 3, which represents:

- fig.l, secțiune longitudinală prin sculă;- fig.l, longitudinal section through the tool;

- fig.2, vedere din stînga a sculei;- Fig. 2, left view of the tool;

- fig.3, secțiune după planul I-I.- fig. 3, section according to plan I-I.

Scula conform «invenției este formată dintr-un corp central 1, cuprins de un cilindru mobil 2, în care sînt practicate niște suprafețe de reglare a, ce susțin, radial, niște role de sprijin 3 și niște role de urmărire 4, cuprinse circumfcrcnțial dc un cilindru - colivie 5, solidar cil corpul 1, prin intermediul unui știft 6, iar radial, de niște cleme elastice 7 și 8. Așchierea este realizată de un cuțit radial 9, reglat, la dimensiune, cu un știft filetat 10, prin intermediul unei tije 11. Blocarea cuțitului este asigurată, în poziția de așchiere, de un știft filetat 12. Reglarea radială a rolelor 3 și 4 se realizează prin rotirea cilindrului cuprinzător 2 cu ajutorul unei chei cu ploturi așezate în niște locașuri b, practicte în cilindrul 2. Blocarea în poziția de lucru a rolelor se face cu un șurub 13 prin intermediul unei șaibe profilate 14. Admisia lichidului de răcire se realizează prin exteriorul sculei, iar evacuarea acestuia împreună cu așchiile rezultate se face prin interiorul sculei fixată în bara de sprijin prin intermediul unui alezaj cu filet dreptunghiular C.The tool according to the invention is formed by a central body 1, comprised of a movable cylinder 2, in which some adjusting surfaces of, which support, radially, support rollers 3 and follow-up rollers 4, circumscribed dc are practiced. a cylinder - cage 5, integrally with the body 1, by means of a pin 6, and radially, by elastic clips 7 and 8. The cut is made by a radial knife 9, adjusted, to size, with a threaded pin 10, by means of of a rod 11. The locking of the knife is ensured, in the cutting position, by a threaded pin 12. The radial adjustment of the rollers 3 and 4 is done by rotating the integral cylinder 2 by means of a key with plots placed in some places b, practiced in cylinder 2 The locking in the working position of the rollers is done with a screw 13 by means of a profiled washer 14. The admission of the coolant is made through the outside of the tool, and its evacuation together with the resulting chips is made through the inside of the tool fixed in the support bar by means of a bore with rectangular thread C.

Prin aplicarea invenției, se obțin următoarele avantaje:By applying the invention, the following advantages are obtained:

- lărgirea domeniului de aplicare;- broadening the scope;

- simplificarea tehnologiei de finisare a alezajelor;- simplification of the boring finishing technology;

- îmbunătățirea siguranței în exploatare.- improving safety in operation.
