Tappitapit

Mitä eroa on puristussovituksella ja liukusovituksella?

• Hieman tapin halkaisijaa pienempi reikä on tarkoitettu käytettäväksi puristussovitettujen tappien kanssa, joiden toleranssi on hieman ylimitoitettu. Toisaalta liukastuvat vaarnatapit liukuvat helposti reiässä rajoittaen liikettä ilman lisälaitteita.
• Puristussovitetut vaarnatapit tulee asentaa kulmapuristimella. Älä koskaan käytä vasaraa, sillä se voi vahingoittaa tappia ja aiheuttaa sen epäonnistumisen. Slip fit vaarnatapit ovat yksinkertaisia ​​ja joustavia asentaa käsin.

What should I do if a dowel pin becomes stuck during installation or removal?

If a dowel pin becomes stuck, applying a penetrating lubricant or heat to the surrounding area can help loosen it. To prevent mating component damage, do not overuse the driver.

Can dowel pins be removed if needed?

Yes, dowel pins can be removed using tools such as drift punches or puller tools designed for that purpose. Pull out dowel pins, in particular, are designed for easy extraction by screwing in a bolt or rod.

How do I determine the correct size of dowel pins to use?

Consider factors like the application requirements, the materials being joined, and the desired fit (such as clearance, interference or transition fit).

What is the difference between press fit and slip fit dowel pins?

Press fit dowel pins are inserted into pre-drilled holes with a tight interference fit for a precise alignment and to prevent relative movement between components. They are usually installed by pressing or hammering. In contrast, slip fit dowel pins fit into pre-drilled holes with a looser tolerance and allow easier hand insertion & removal.
