Uyenza njani iodolo emincinci yoLwandiso lwemithombo?

Udinga intwasahlobo encinci yolwandiso lwesixhobo sakho esitsha, kodwa iikhathalogu zesitokhwe azinanto ifanelekileyo. Iprojekthi yakho imisiwe, ukulinda inxalenye encinci ebonakala ingenakwenzeka kwimvelaphi.

Ukucwangcisa ngokwesiko intwasahlobo encinci yolwandiso, kufuneka unike iinkcukacha ezine ezibalulekileyo: idiameter yocingo, i-diameter yangaphandle yeekhoyili, ubude phakathi kwamagwegwe, kunye nohlobo lwamagwegwe afunekayo. Ezi nkcukacha eziphambili zivumela umenzi ukuba avelise ngokuchanekileyo intwasahlobo.

I've seen many innovative product designs get delayed by a simple, intwasahlobo encinci. Ingxaki kukuba "incinci" isn't a specific enough measurement for manufacturing. A spring that's small for an automotive application could be gigantic for a medical device. Ukufumana intwasahlobo yesiko lakho lenziwe ngokukhawuleza nangokuchanekileyo kuxhomekeke ekuboneleleni ngokucacileyo, ulwazi oluchanekileyo. Let's break down exactly what a spring maker like me needs to create the perfect part for you.

What Are the Most Critical Dimensions to Provide?

You sent a drawing for a small spring, kodwa umenzi ucela ulwazi oluthe kratya. You're not sure which numbers are the most important, causing delays in your project.

Imilinganiselo emine ebalulekileyo yi-wire diameter, Idayimitha yangaphandle, ubude ngaphakathi kwamagwegwe, kunye nodidi lwezinto. These numbers control the spring's pulling force, how it fits into your assembly, kwaye iya kuhlala ixesha elingakanani kwindawo yayo yokusebenza.

Ekuqaleni komsebenzi wam, umthengi ucele "intwasahlobo encinci etsala malunga neponti enye yamandla." Esi sisicelo esixhaphake kakhulu kodwa esinzima. Ngaphandle kwemilinganiselo engundoqo, kukho amawaka oyilo lwentwasahlobo olunokwenzeka olunokuthi luhlangabezane naloo mfuno. It's like asking a builder for a "small room" ngaphandle kokunika nayiphi na imilinganiselo. Sifuna iplani. Ukubonelela ngedamitha yocingo, Ikhoyili ububanzi, kwaye ubude businika ubungakanani obuchanekileyo kunye nokumila. Specifying the material tells us what it's made of. Ngala maqhekeza amane olwazi, we can calculate the spring's performance and give an accurate quote.

UMfanekiso weNtwasahlobo yakho

Le milinganiselo emine isisiseko soyilo lwakho lwentwasahlobo yesiko.

• Ububanzi bocingo (d): Oku bubunzima bocingo ngokwalo. It has the biggest impact on the spring's strength and force.
• Ububanzi bangaphandle (OF): This is the width of the spring's coil body. It determines if the spring will fit into your assembly.
• Length Inside Hooks (LIH): This is the total length of the spring from the inside of one hook to the inside of the other when it is relaxed.
• Isixhobo: The type of wire used (I-E.G., Yenziwe ngentsimbi eshayinayo 302, Ucingo lomculo). This affects corrosion resistance, ubomi bokudinwa, kunye neendleko.

How Do You Specify the Pulling Force You Need?

Your prototype spring is either too weak to do its job or so strong it's bending other parts. You need to control the force, but you don't know how to ask for it.

You can specify the force by providing a "spring rate" or by stating the load it should have at a specific extended length. Umzekelo, "The spring needs to provide 5 lbs of force when stretched to 2 inches long."

This is where we move from just the shape of the spring to its actual function. A customer once needed a spring for a small lid. Their first prototype was too strong and made the lid snap shut dangerously. The second was too weak and the lid wouldn't stay closed. The problem was they were only focused on the spring's size. I explained that we needed to define the force. Sasebenza kunye ukuze sibone ukuba bafuna ispringi 2 I-Newtons zamandla kubude obude obuyi-25mm. Ngaloo nxalenye enye yedatha, sihlengahlengise uyilo kwaye isampuli elandelayo yasebenza ngokugqibeleleyo.

Defining the Spring's Job

Kukho iindlela ezimbini eziphambili zokusixelela ukuba intwasahlobo kufuneka yomelele kangakanani.

• Ireyithi yaseNtwasahlobo: Lo ngumlinganiselo wamandla afunekayo ukolula intwasahlobo ngomgama othile (I-E.G., lbs/intshi okanye N/mm). It defines the spring's stiffness.
• Layisha kuBude: Le yindlela ethe ngqo. Ukhankanya umthwalo ojoliswe kuwo kubude obuthile obandisiweyo. Oku kuhlala kulula kubayili abawaziyo amandla achanekileyo abawadingayo kwindlela yabo.

Loluphi uhlobo lweHook oluphela olufunwa yimithombo emincinci?

Amakhonkco kwintwasahlobo yakho encinci ahlala eqhekeka okanye etyibilika kwizithuba zawo zokuxhoma. The standard hooks you've tried are not working for your compact and delicate design.

Kwimithombo emincinci, amagwegwe kufuneka akhethwe ngokusekelwe kwimithintelo yendawo kunye noxinzelelo oluya kunyamezela. Ukhetho oluqhelekileyo lubandakanya izikhonkwane zoomatshini zokuqina kunye neekhonkco ezandisiweyo zokufikelela kwiindawo ezithile zokudibanisa. Uyilo lwe hook lubaluleke kakhulu njengomzimba wasentwasahlobo.

Ndikhumbula ndisebenza kwiprojekthi yesixhobo sombane esincinci apho ihuku eqhelekileyo yayinkulu kakhulu. Yayichukumisa elinye icandelo kwaye ibangela isiphaluka esifutshane. The spring's body was perfect, kodwa igwegwe lenze ukuba lingasetyenziswa. Isisombululo yaba sisi hook yesiko[^ 1] kunye nelophu encinci kakhulu kunye nokuqhelaniswa okuthe ngqo okwakuyigcina icacile kwezinye izinto zombane. Kwimithombo emincinci, indawo yinto yonke. Kwakhona kufuneka ucinge ngoxinzelelo. I-crossover hook elula ingabonakala ilungile, kodwa idala iqondo eliphezulu loxinzelelo elinokuthi liphuke emva kokusetyenziswa ngokuphindaphindiweyo. I-hook encinci yomatshini idla ngokuba lukhetho oluthembekileyo kakhulu, nokuba kubiza ngaphezulu kancinci ukuvelisa.

Ukukhetha uQhagamshelwano oluLungileyo

Ikhonkco idibanisa intwasahlobo yakho kwimveliso yakho, kwaye kufuneka ilingane ngokugqibeleleyo.

• Uhlobo lweHook: Ubume be hook bubaluleke kakhulu ukomelela kunye nokufaneleka. Iihuku zoomatshini zomelele ngakumbi kuneegwegwe ezinqamlezileyo. Iiluphu ezipheleleyo zingasetyenziselwa ukutyibilika phezu kweposti.
• Hook Orientation: I-angle yeekhonkco ezihambelanayo (I-E.G., emgceni kwi 0 izidanga, okanye kwi 90 izidanga) inokuchazwa ukwenza ukudibanisa kube lula.
• Hook Ukuvula: Ubungakanani besithuba esisekupheleni kwe hook sinokwenziwa sincinci ukunqanda ukuba singatyibiliki.

Ukuqukumbela

Ukucwangcisa ngokwesiko imithombo yolwandiso oluncinci, nika imilinganiselo echanekileyo, chaza amandla afunekayo, kwaye ukhethe ngononophelo uyilo hook. Oku kucaca kuqinisekisa ukuba ufumana inxalenye egqibeleleyo yemveliso yakho.
