What is the Bending Process of Admiralty Brass Tubes?
The main bending methods that you can use on your admiralty brass tubes are:
· Ram-type Bending Method
The primary tool in this method is a ram that uses hydraulic force to push the tube against a set of pivot blocks or rollers.
Besides, the resulting bend features a centerline radius, which can be thrice or four times the overall diameter of the tube.
The process results in the stretching of the tube’s internal diameter substantially since there is no support here.
It is an ideal method to use for square tubing specifications.
Though it is a cheaper method than the others, it is not a reliable option due to several limitations.
· Roll Bending Method
It is the best method to use on large tube bends.
It involves the use of three rolls that you position in a pyramid system.
The designs of the pyramid system can either be horizontal or vertical.
As the rolls rotate, they form a specific bend with a large radius.
· Compression Bending Method
A compression dies, or a roller is a primary tool that you use to bend your admiralty brass tube here.
A stationary die holds the tube in position during the bending process.
It is the best option to use when bending symmetrical admiralty brass tubes.
The resulting bend has an overall diameter which is thrice that of the tube.
· Rotary Draw Bending Method
A rotary draw bending method uses a pressure die to hold the straight tangent of the admiralty brass tube.
The use of a mandrel supports the interior part of the tube around the bending section.
A pressure dies present offers support to the tube’s outer diameter.
These tools ensure the tube has enough support both on the interior and exterior parts.
This results in an adequate bend with no tension on either side.
