Umehluko phakathi kwe-high frequency ne-medium frequency quenching in imishini yokuqeda imvamisa ephezulu

(1) I-High-frequency quenching inongqimba olungajulile oluqinile (1.5 ~ 2mm), ukuqina okuphezulu, i-workpiece akulula ukuyi-oxidize, inokuguqulwa okuncane, ikhwalithi enhle yokucisha kanye nokusebenza kahle kokukhiqiza okuphezulu, futhi ifanele izingxenye ezisebenza ngaphansi kokungqubuzana. izimo, ezifana amagiya ngokuvamile amancane, Shafts (izinto ezisetshenziswa 45 # steel, 40Cr);

(2) Ungqimba oluqinile lwe-intermediate quenching lujulile (3 ~ 5mm), olufanele izingxenye ezingaphansi kokusonteka nokucindezela imithwalo, njengama-crankshafts, amagiya amakhulu, ama-spindle omshini wokugaya, njll. (izinto ezisetshenziswayo ziyi-45 # insimbi, 40Cr, 9Mn2V kanye ne-ductile iron) .

(3) Amagiya e-modulus amancane naphakathi nendawo kanye nezingxenye ze-shaft zosayizi ophakathi noma omncane.

(4) Ukushisa kokungenisa imvamisa emaphakathi 2500～8000Hz 2～10 Amashafu amakhulu namagiya emodulus amakhulu naphakathi.

Ngokusho kwemvamisa yamanje, ukucisha ukushisa kwe-induction kungahlukaniswa kube: imvamisa ephezulu yokucisha i-100-1000kHz. Imvamisa emaphakathi ivala i-1-10kHz. Imvamisa yamandla ivala i-50Hz.

1. Ukuqina kongqimba olungaphezulu kuphezulu ngo-2-3HRC kunokokucisha okuvamile, futhi kunokuqina okuphansi, amandla okukhathala, nokuqina komthelela. Ngokuvamile, i-workpiece ingakhuphuka ngo-20-30%.

2. I-deformation incane, futhi ukujula kwesendlalelo sokucisha kulula ukulawula.

3. Insimbi eshibhile eqinile ephansi ingasetshenziswa, ukusebenza kulula ukubona imishini kanye ne-automation, ukukhiqiza kuphezulu, ukuphakama kwemvamisa yamanje, kuya kuba mncane ungqimba oluqinile.

(5) Imishini yokucisha imvamisa ephezulu imvamisa ingu-1-2mm, ukucisha imvamisa emaphakathi ngokuvamile kungu-3-5mm, futhi ukucisha imvamisa yamandla kungafinyelela>=10-15mm.

(6) Ukushisa kwe-high-frequency induction: imvamisa yamanje ngu-100-500 kHz (kHz), futhi ukujula kokuqina okusebenzayo kungu-0.5-2 mm (mm). Isetshenziselwa ikakhulukazi izingxenye ezincane neziphakathi nendawo ezidinga ungqimba oluqinile oluqinile, njengamagiya amancane e-Modular, ama-shafts amancane naphakathi, njll.

(7) Ukushisa kwe-intermediate frequency induction: imvamisa yamanje ingu-500 kuya ku-10000 Hz (Hz), futhi ukujula kokuqina okusebenzayo kungu-2 kuya ku-10 mm (mm). Isetshenziselwa ikakhulukazi izingxenye ezidinga ungqimba oluqinile olujulile, njengamagiya anemodulus ephakathi, amagiya amamojula amakhulu, ama-shaft anobubanzi obukhudlwana, njll.
