Which Fields Are The Dowel Pins Mainly Used In
Positioning pins are widely used, generally in some mechanical motion equipment, mainly used for position stability based on two-dimensional space, so where are the main applications of positioning pins
Dowel pins are the most widely used in molds. Including stamping mold, injection mold and so on. Their precision requirements are particularly high, and if it is only by the bolt to fix the template is certainly not, so only with the help of the positioning pin to achieve the purpose of positioning, or to prevent the installation of the position, the direction of the wrong and so on.Get more news about dowel pin,you can vist our website!
Spring positioning pin consists of a pin shaft, elastic ring, spring, steel ball, elastic ring two open end points are installed in the two holes at one end of the pin shaft, the other end of the blind hole is equipped with a spring and steel ball, steel ball on the spring, but after the blind hole rivet small, so that the ball can only move to the blind hole, and can not fall off.
HOW TO SELECT THE RIGHT DOWEL PIN
Dowel pins are commonly used in many industries including automotive, aerospace, agriculture and transport. They function as a shaft or hinge to hold and align assembled parts in place – and if you are a manufacturer working with assemblies of any kind, the chances are that you are already familiar with precision dowels. But if you’d like to know more about these simple, yet highly effective fasteners, then read on:
Dowel pins are manufactured as solid, cylindrical metal pins to precise diameters and lengths. They are available in a wide range of sizes, styles and materials.
Dowel pin sizes:
Standard dowel pin sizes include metric sizes from M1 to M20 diameter – or 1/16” to 1” diameter in imperial sizes—with varying options of lengths. We specialise in custom-made small diameter precision dowels which range from 0.80mm to 6.00mm diameter and up to 150mm in length and can accommodate non-standard sizes when an ‘off the shelf’ option won’t fit the needs of a specialist application.
Radius or chamfer – what’s the difference?
There are lots of options to consider when selecting a dowel pin. Precision dowels are produced with either a double chamfer or radius, or with a chamfer at one end and a radius at the other.
Both finishes are designed to remove sharp edges and aid the dowel pins insertion. A radius is designed to be rounded off at the ends, whereas a chamfer is a slanted finish created at the corner.
Threaded and tapered dowel pins
Threaded dowel pins are useful if the pin needs to be removed from a blind hole at any point after installation. In this situation, a pin can be tapped with an internal thread and be removed quickly using a dowel pin extractor tool – and the pin can then be reused.
Tapered dowel pins have a slightly larger diameter at one end, usually a 1 in 50 taper for metric sizes and 1 in 48 for imperial. They are often used for low torque positioning and locking in many types of mechanical assemblies.
Installing precision dowels
Dowel pin installation is designed to be fast and easy; the pins can simply be pressed in for the best results—you should never drive the pin into the hole with force. The simplicity of these types of pin means that there are no complicated or secondary operations required, which means production times are faster.
