Metal tubes are used for various structural purposes and used by us in our daily lives from bicycles, handlebars, furniture frames to heavy industrial purposes such as pipelines etc. The tube bending aims at getting a smooth round bend devoid of any wrinkles. When sheet metal is bent to form a tube, the outer part of the metal spreads while the inner portion actually compresses to thicken. The three basic tools that are a must to get this process done, include, the bend die used to form the bend, clamp die which helps in holding the metal in position and thirdly, the pressure die.
Many customers tend to use a thinner wall for their projects to reduce material costs. However, thinner wall tubing may require more labor to bend….(as in some instance it may not be able to hold the roundness of the tube as it is bent and result in ripples or wrinkling in the bend). In some cases the additional labor costs outweigh the material savings therefore it may or may not be beneficial to use a thinner wall material.
You will also have to bend the other end of the pipe this time from the bottom; this will touch the ground so you will have to do some measuring so that you will get the right distance. You will have to shape this pipe at a fifty five degree from your vertical portion; if this is done correctly then the shape of the pipe should be able to mold onto the ground.
Rolling is effective when the material – metal, plastic, glass, whatever – must be bent a great deal. For instance, it can produce bends up to 360 degrees. This method is ideal for producing steel coils, spiral staircases and the like.
Attach KP-LOK tubing bender a light gauge chain to the loop at the top of the chandelier. Attach it to a hook that is supported either directly to the ceiling joist, or by a supporting bracket to handle the weight of the chandelier. Add the candles on the plates and light them.
Typical bending processes with parts that have more than one bend require a straight length between the bends. Standard tooling can accommodate parts that allow a distance between bends of at least 3 times the tube diameter. Parts that have a distance less than 3 times the diameter are possible to produce, but may require special tooling which in turn increases tooling charges. An exception to this rule exists with a different bending technology, the Nissin bender. This technology applies to 1-1/4″ O.D. and smaller bent on a radius that is 3 times the diameter.
The pressure die should be adjusted for a light pressure against the tube. The purpose of the pressure die is to keep the tube against the bend die through the duration of bending. The pressure die also keeps the mandrel from bending and maintains a straight tube between tangent points of bends (the portion of ubing left on the mandrel after steel bending). The location of the mandrel affects the amount of springback. The mandrel in a forward position (toward tangent) will stretch the material on the outside of the bend more than is necessary. This increases the length of material on the outside beyond that which is required to make a bend. When the bent tube is removed from the bend die, it will conform to the die and there will be little or no springback.
