Hydraulic rod, push-pull rod quenching le tempering line line

1. Litlhoko tsa tekheniki

1. Sepheo

E sebelisoa bakeng sa ho futhumatsa ka kakaretso le ho futhumatsa lithupa tsa hydraulic le melamu ea push-pull.
2. Mekhahlelo ea workpiece

1 ) Lisebelisoa tsa lihlahisoa: 45 # tšepe, 40Cr , 42CrMo

2 ) Mohlala oa sehlahisoa (mm) :

Diameter: 60 ≤ D ≤ 150 (tšepe e tiileng e chitja)

Bolelele: 2200mm ~ 6000mm;

3 ) Tšepe e chitja e futhumatsoa ho mocheso oa ho tima ka makhetlo a mahareng ebe e pholile bakeng sa phekolo ea ho tima, ‘me phekolo ea tempering e etsoa inthaneteng.

Ho tima mocheso oa mocheso: 950 ± 10 ℃;

Mocheso oa ho futhumatsa: 650 ± 10 ℃;

4) Matla a kenang: 380V ± 10%

5) Tlhokahalo ea tlhahiso: 2T / H (ho latela tšepe e chitja ea 100mm)

3. Litlhoko tsa tekheniki bakeng sa ho tima le ho futhumatsa lisebelisoa:

1 ) Kakaretso ea boima ba holim’a sefate kaofela ke likhato tse 22-27 HRC, boima bo fokolang bo ke ke ba ba tlase ho likhato tse 22, ‘me boima bo loketseng ke likhato tse 24-26;

2) Ho thatafala ha shaft e le ‘ngoe e tlameha ho ba ntho e ts’oanang, boima ba sehlopha se tšoanang le bona bo tlameha ho ba bo ts’oanang,’ me ho tšoana ha shaft ho tlameha ho ba ka hare ho likhato tse 2-4.

3) Mokhatlo o tlameha ho ba o ts’oanang mme thepa ea mochini e fihlela litlhoko:

a. Matla a tlhahiso a kholo ho feta 50kgf/mm²

b. Matla a matla a maholo ho feta 70kgf/mm²

c. Elongation e kholo ho feta 17%

4 ) Sebaka se tlaase ka ho fetisisa sa bohareng ba selikalikoe se ke ke sa e-ba tlaase ho feta HRC18, ntlha e tlaase ka ho fetisisa ea 1 / 2R e ke ke ea e-ba tlaase ho feta likhato tsa HRC20, ‘me ntlha e tlaase ka ho fetisisa ea 1 / 4R e ke ke ea e-ba tlaase ho feta likhato tsa HRC22.

2. Litlhaloso tsa workpiece

Ho ea ka litlhoko tsa moreki, re fana ka lihlopha tse latelang tsa li-sensor bakeng sa tšepe e chitja ea 45-150.

Ho ea ka tafole e hlalositsoeng ke moreki, ho hlokahala li-inductors tse 4, li-sete tse 4 ka ‘ngoe bakeng sa ho tima le ho futhumatsa. Sebaka sa ho futhumatsa sa workpiece ke 40-150mm . Sensor e timang mocheso oa ho nyoloha e nka moralo oa 800mm × 2, sensor e timang mocheso o ts’oanang e nka moralo oa 800mm × 1, ‘me mochini o thibelang mocheso o timang o nka moralo oa 800mm × 1 ho netefatsa ho futhumala ho tšoanang. Karolo ea ho futhumatsa e entsoe ka mokhoa o ts’oanang.

Boraro, tlhaloso ea phallo ea tšebetso

Ntlha ea pele, ka letsoho u behe li-workpieces tse hlokang ho futhumatsoa ka mola o le mong le lesela le le leng holim’a rack ea polokelo ea lijo, ebe thepa e romeloa butle-butle ho rack ea ho fepa ka mochine oa thepa, ebe thepa e kenngoa ka har’a lijo. rolara e sekametseng ka moqomo wa moya. Rolara e sekametseng e khanna thepa ea bar pele ebe e romela thepa ho inductor ea ho futhumatsa e tima. Ebe workpiece e halefile ke quenching futhumatsang karolo, ‘me quenching futhumatsang e arotsoe ka quenching futhumatsang futhumatsang le tima quenching ho boloka mocheso futhumatsang. Karolong ea ho tima le ho futhumatsa, phepelo ea motlakase ea 400Kw e mahareng e sebelisoa ho futhumatsa sesebediswa, ebe ho sebelisoa lisebelisoa tse peli tsa 200Kw tsa maqhubu a mahareng a motlakase bakeng sa ho boloka mocheso le ho futhumatsa.

Ka mor’a hore ho futhumatsa ho phethoe, workpiece e khannoa ke rolara e sekametseng ho feta ka har’a selikalikoe sa metsi a timang bakeng sa ho tima. Ka mor’a hore ho tima ho phethoe, e kena ka har’a mochine o futhumatsang mocheso bakeng sa ho futhumatsa. Ho futhumatsa ho boetse ho arotsoe ka likarolo tse peli: ho futhumatsa mocheso le ho boloka mocheso oa mocheso. Karolo ea ho futhumatsa e sebelisa matla a 250Kw a mahareng a maqhubu a mahareng, ‘me karolo ea ho boloka mocheso e sebelisa lisebelisoa tse peli tsa 125Kw matla a maqhubu a mahareng. Ka mor’a hore ho futhumatsa ho phethoe, thepa e ntšoa, ‘me ts’ebetso e latelang e etsoa.
