Luluphi uhlobo lonyango lobushushu olunokuthi umatshini wokuqiniswa kwe-frequency ephezulu ukwenza kwi-coil spring?

Idayamitha yemathiriyeli yecandelo elingqukuva inkulu kune-12mm, ubude becala lemathiriyeli yecandelo loxande bukhulu kune-10mm, kwaye i-coil spring enobunzima bepleyiti obukhulu kune-8mm iveliswa ngokubanzi ngokubunjwa okushushu. Inkqubo ethile yintsimbi yokuhlola-ukusika izinto zokufudumeza intonga eshushu icoil spring-shaping-hot shape -Tempering-end surface grinding-shot peening-hot pressure treatment-flaw discover-painting okanye phosphating spray-spection-packaging. Namhlanje, ndiza kukuxelela ukuba zeziphi iinkqubo ezinokuthi zenziwe ngumatshini wokuqiniswa kwe-high-frequency induction.

1. Ukufudumala kwebha ngokuqhelekileyo kuqhutyelwa ngumatshini wokucima i-high-frequency kunye nokutya okuzenzekelayo kunye nokukhutshwa. Ububanzi bezinto eziphathekayo bunokufikelela kwi-60mm, kwaye ubude akufanele budlule i-8m. Ubushushu bobushushu bentsimbi yentsimbi ngokuqhelekileyo bungama-880-950 ℃.

2. I-Coiling, usebenzisa i-computer-controlled controlled cored or coreless hot-coiling machine, ene-process diameter ye-20-60mm, kunye ne-hot-coiling the heat-heated bar material kwi-coil compression spring yenkcazo efunekayo. Ubushushu bentwasahlobo emva kokwenziwa kwekhoyili eshushu kufuneka ibe ngaphezulu kwe-840℃, elungele ukucinywa ngokuthe ngqo. Oko kukuthi, ucinywa kwioli kwi-50-80 ° C. Ubushushu betanki yeoli yasentwasahlobo kufuneka ilawulwe ngaphakathi koluhlu lwe-120-180 ℃ ukuthintela ukuguqulwa kwayo kunye nokunciphisa uxinzelelo lokucima. Emva kokucinywa ngumatshini wokuqiniswa kwe-frequency induction, ubunzima bentwasahlobo bukhulu kune-54HRC.

3. Ukufudumala, intwasahlobo emva kokucima kufuneka ihlanjululwe ngaphakathi kwe-2h ukukhusela ukucima ukuqhekeka. Iziko lobushushu lithatha ulawulo lwe-PLD, ukuze ubushushu bobushushu bulawuleke ngaphakathi kwe-± 3 ℃, kwaye ubushushu bobushushu yi-400-450 ℃. Emva kokufudumala, ubunzima bentwasahlobo bunokufikelela kwi-45-50HRC. Imithombo ejongene ne-deformation ngexesha lenkqubo yokunyanga ukushisa iya kuphathwa ngokwahlukileyo, kwaye inkqubo yokubunjwa kufuneka yongezwe ngokubanzi.
