1. Ma'anar ƙirƙira sanyi

Ƙirƙirar sanyi, wanda kuma aka sani da ƙirƙira ƙarar sanyi, tsari ne na masana'anta da kuma hanyar sarrafawa. Ainihin daidai yake da tsari na stamping, tsarin ƙirƙira sanyi ya ƙunshi kayan ƙirƙira da kayan aiki. Amma kayan da ake sarrafa stamping galibi faranti ne, kuma kayan da ake sarrafa kayan sanyi galibi waya ne. Japan (JIS) da ake kira sanyi ƙirƙira (sanyi ƙirƙira), China (GB) ake kira sanyi heading, waje dunƙule factory kamar kiran kai.

2. Basic Concepts na sanyi ƙirƙira

Ƙirƙirar sanyi tana nufin zafin sake recrystallization na ƙarfe da ke ƙasa da nau'ikan ƙarar da ake samu. A cewar ka'idar metalology, recrystallization zazzabi na daban-daban karfe kayan ne daban-daban. T = (0.3 ~ 0.5) T narke. Mafi ƙarancin recrystallization na ƙarfe na ƙarfe da mara ƙarfe. Ko da a yanayin zafi na ɗaki ko yanayin zafi na yau da kullun, tsarin samar da gubar da kwano ba a kiran ƙirjin sanyi ba, amma ƙirƙira mai zafi. Amma ƙarfe, jan ƙarfe, sarrafa aluminum a yanayin zafin jiki ana iya kiran shi ƙirƙira sanyi.

A cikin ƙarfe, ƙirƙira kayan da aka yi zafi sama da zazzabi na recrystallization (kimanin 700 ℃ don ƙarfe) ana kiran ƙirƙira mai zafi.

Don ƙirƙira ƙarfe, zafin sake recrystallization da ke ƙasa kuma sama da ƙirƙirar zafin jiki na yau da kullun ana kiransa ƙirƙira mai dumi.

Amfanin kan sanyi (extrusion)

A cikin samar da fastener, fasahar sarrafa sanyi (extrusion) fasaha ce babbar fasahar sarrafawa. Tushen sanyi (extrusion) yana cikin nau'in sarrafa matsi na ƙarfe. A cikin samarwa, a yanayin zafi na al'ada, ana amfani da ƙarfen da ƙarfi daga waje, don haka ƙarfe a cikin ƙayyadaddun ƙirar ƙira, ana kiran wannan hanyar galibi taken sanyi.

Samar da duk wani fastener ba wai kawai nakasar hanyar sanyi ba ne, ana iya gane shi a cikin yanayin sanyi, ban da nakasawa, amma kuma yana tare da extrusion gaba da baya, extrusion composite, yankan naushi, mirgina da sauran su. hanyoyin nakasa. Don haka, sunan taken sanyi a samarwa suna ne kawai na al'ada, kuma yakamata a kira shi taken sanyi (squeeze) daidai.

Cold heading (extrusion) yana da yawa abũbuwan amfãni, shi ne dace da taro samar da fasteners. Babban fa'idodinsa sun haɗa da abubuwa masu zuwa:

High amfani kudi na karfe, sanyi heading (matsi) ne a hanya na kasa, babu yankan, kamar aiki sanda, Silinda shugaban hex socket sukurori, hex shugaban aron kusa machining Hanyar, da amfani kudi na karfe a 25% ~ 35%, da kuma kawai tare da hanyar sanyi (matsi), kuma yawan amfani da shi na iya kaiwa 85% ~ 95%, kai ne kawai, wutsiya da hex head yanke wasu tsarin amfani.

Babban yawan aiki: idan aka kwatanta da yankan gabaɗaya, taken sanyi (extrusion) haɓaka ingantaccen aiki shine sau da yawa sama da.

Kyakkyawan Properties na inji: sanyi heading (extrusion) sarrafa sassa, saboda karfe fiber ba a yanke, don haka ƙarfi ne mafi alhẽri daga yankan.

Dace da atomatik samar: fasteners (har ma da wasu na musamman-dimbin sassa) dace da sanyi take (extrusion) samar da su ne m sassa, dace da high-gudun atomatik sanyi kan inji samar, shi ne kuma babban hanyar taro samar.

A cikin kalma, hanyar sanyi (extruding) hanya ce ta sarrafawa tare da fa'idar tattalin arziƙi mai fa'ida, wanda ake amfani da shi sosai a masana'antar fastener. Har ila yau, hanya ce ta ci gaba da ake amfani da ita a gida da waje tare da babban ci gaba.
