One of Chinese manufacturer of Special Rivets, offering excellent quality at a competitive price, is Notin. Feel free to get in touch.
In the field of mechanical manufacturing and assembly, rivets are a common fastener used to professionally connect two or more parts. According to the degree of standardization, rivets can be divided into two categories: standard rivets and non-standard rivets. The size, shape and material of standard rivets are uniformly specified, while non-standard rivets are customized according to specific needs. The following will introduce the characteristics and applications of non-standard rivets from multiple aspects.
What are non-standard rivets?
Non-standard rivets are also called special rivets. They refer to rivets that do not meet national standards or industry general standards. Their size, material, structure and other parameters are designed and manufactured according to the specific needs of customers. Due to the different connection requirements of different industries and equipment, standard rivets may not meet the requirements of certain special scenarios, so non-standard rivets came into being.
What are the characteristics of special rivets?
(1) Strong customization: Non-standard rivets can be personalized according to factors such as the use environment, stress conditions, and assembly methods to ensure that they perform well in actual applications.
(2) Diverse materials: In addition to common carbon steel and stainless steel, non-standard rivets can also be made of special materials such as aluminum alloy, copper alloy, titanium alloy, etc. to meet different corrosion resistance, strength and weight requirements.
(3) Flexible structure: The structure of non-standard rivets can be adjusted according to needs, such as head shape, stem diameter, length, etc., and can even be designed to be hollow, semi-hollow or other special shapes.
Jernnitter, også kendt somnitter i kulstofstål, er en type befæstelse, der typisk er lavet af kulstofstål med overfladebehandlinger såsom galvanisering. De tilbyder en trækstyrke på 400-500 MPa og er velegnede til applikationer såsom elektrisk udstyr. For at imødekomme forskellige nitningsapplikationer fremstilles jernnitter typisk som semi-hule eller solide nitter. Jernnitter er en grundlæggende, men afgørende mekanisk komponent, der er meget udbredt på grund af deres styrke, overkommelige priser og brugervenlighed.

Vores jernnitter til svampehoved, som navnet antyder, har et svampeformet hoved med enten en semi-hul eller solid kerne. Hovedet er typisk større, hvilket giver en god bæreflade. Denne struktur giver mulighed for deformation under installation, enten gennem ekstrudering eller specialiseret værktøj, for sikkert at forbinde to eller flere materialer. Fremstillet af jern, er de typisk galvaniseret eller behandlet med andre overfladebehandlinger for korrosionsbestandighed.

Strukturelt er nittehovedet fladt, skiveformet, og kroppen er cylindrisk. Slutningen er specielt bearbejdet til at danne en forstyrret struktur. Efter installation får tryk eller slag kroppen til at udvide sig, hvilket danner et mekanisk indgreb med hulvæggen for at opnå en stramningseffekt. Sammenlignet med nitter med runde hoveder eller forsænkede hovednitter har det flade hoveddesign betydelige fordele i kraftfordeling og kontaktareal. For eksempel, når det udsættes for forskydningskraft, kan dets skiveformede hoved sprede belastningen til et større område, hvilket effektivt reducerer trykket pr. arealenhed.

Denne form gør det muligt for nittens hoved at sidde i plan med overfladen af den tilsluttede komponent efter installationen, hvilket resulterer i et glat udseende. Dette er særligt velegnet til applikationer, hvor overfladens planhed er kritisk. Kom til Nuote Metals for at tilpasse din ønskede nitte med forsænket hoved i jern. Vores ingeniører, med over 10 års erfaring, er dybt fortrolige med produktion af forskellige nittetyper.

Den hule del optager ca. en tredjedel til halvdelen af nittelegemets længde. Dette design gør det muligt for nitten at opnå en fastgørelseseffekt gennem ekstruderingsdeformation under installationen. Sammenlignet medsolide nitter, halvrørsnitter er kendetegnet ved let vægt, nem installation og bred anvendelighed; sammenlignet med helhule nitter giver de højere styrke og stabilitet. Halvrørsnitter kræver ikke komplekst udstyr under installationen og kan normalt suppleres med manuelt eller pneumatisk værktøj. Derfor er de begunstigede på mange områder. Nuote Metals har specialiseret sig i produktion af halvrørsnitter med et komplet udvalg af forme og byder velkommen til tilpasning.
