Classification of self-tapping screw structures

Mohaho wa sekoti sa ho ithatela. Sekoti se seng le se seng sa ho itlama se entsoe ka likarolo tse tharo: hlooho, molamu le pheletso ea molamu. Sekoti se seng le se seng sa "self tapping" se entsoe ka likarolo tse 'ne: ponahalo ea hlooho, mokhoa oa ho hula, mofuta oa khoele, tsela ea mohatla.

1. Ponahalo ea hlooho

Lihlooho li hlaha ka mefuta eohle le boholo. Ho na le molomo o pota-potileng (halofo ea hlooho e chitja), hlooho e chitja e chitja, molomo o chitja (ka lephepho), hlooho e chitja e chitja (e nang le pad), hlooho ea pan, hlooho ea pan (e nang le pad), hlooho ea countersunk, hlooho ea halofo ea countersunk, cylindrical. hlooho, spherical cylindrical top, lenaka hlooho, hexagonal hlooho, hexagonal flange hlooho, hexagonal flange (e nang le pad).

2. Mokhoa oa ho hula le ho sotha

Screw way e bolela ho kenya le ho fasten screws ha screw head sotter form, ha e le hantle ho na le screw ea kantle le screw ka hare ka litsela tse peli. Ka kakaretso, wrench e ka ntle e lumella torque e kholo ho feta mofuta ofe kapa ofe oa wrench ea ka hare (concave groove). Sekhopo sa ka ntle: sekotla sa hexagonal, hexagonal flange, hexagonal flange, sebopeho sa palesa se hexagonal, joalo-joalo. mohlala, kgutlotharo e ka hare, hexagon e ka hare, hare 12 Angle, clutch groove, six leaf groove, high torque cross groove, joalo-joalo.

3. Mofuta oa khoele ea Screw

Ho na le mefuta e mengata ea likhoele, khoele ea ho tlanya (khoele ea meno e pharaletseng), khoele ea mochini (khoele e akaretsang), khoele ea sekoti sa drywall, khoele ea sekoti sa fiberboard, le khoele e 'ngoe e khethehileng. Ho phaella moo, khoele e ka aroloa ka molumo o le mong (hlooho e 'meli), molumo oa makhetlo a mabeli (lihlooho tse ngata), li-multi-pitch (tse peli-hlooho) le hore na ke meno a makae a lihlooho tse ngata.

4, tsela ea ho qetela

Mokhoa oa ho qetela oa mohatla o kenyelletsa mefuta e 'meli: pheletso ea cone le pheletso ea setsoalle. Leha ho le joalo, ho ea ka litlhoko tsa kopo, karolo e tiisang qetellong ea mohatla e ka hlahisa le ho sebetsana le groove e sebetsang, groove, leqeba kapa karolo e ts'oanang le sebopeho sa twist drill, joalo-joalo. pheletsong e bataletseng, ho na le mekhoa e fapaneng joalo ka pheletso ea molomo o chitja.
