How to calculate the pipe bend and do it with a machine

Advantages of modern benders

simple fact that bending metal pipes with their own hands to put it mildly difficult, but if you know how to calculate the bending and heavy-duty equipment used, it may be easier.Moreover may emerge still extremely unpleasant moments, like flattening or deformation section.The most optimal way to aid more flexible - a pre-preparing them.

For preparation methods include freezing preparations.But it no longer applies in the winter or summer, in the industrial refrigerator.

1. To this must be placed in one end of the pipe water, and the other end to close.The preform is placed in the cold.After freezing the blank bends a lot better and it does not appear deformation.
2. tube is filled with sand plugs sealed twice its diameter.Then drill a couple of holes, so that the gas came out during the heating and did not cause deformations.The marked section for bending heated with a blowtorch and fixed to the tube bender, which unbend and profile and round tube.

By the way, modern technology is able to bend and do it without preparation tubes.

• can not be used to weld and fittings for installation.
• for decorative purposes is much more interesting look design with solid pipes.
• Benders promote compliance with precision dimensions.
• absence of any kind of creases and cracks, and thus perfect technical condition.
• small amount of applied manual labor forces due to electric drive.

How to calculate the bending and select tools for bending

instruments for bending pipes are selected according to the material and the cross section of the header.

Therefore, if you are going to bend the copper products, then you will be quite simple mechanical devices.It can be: manual, hydraulic, lever benders.The ability to cope with curved up to 3 inches in diameter.

For example, for a profiled tubes, as opposed to round, you need to put more effort and physical labor.

Therefore, they use the device with a larger radius of operation.circular cross-section pipes also require high-tech equipment.Domestic manufacturers offer a list of devices that are not inferior to foreign options.

Profilegib (PG-1 and PG-2)

problem of how to calculate the bend, this device is almost decided, therefore, has gained popularity among the newcomers construction due to its inexpensive cost.He and they can use it easy to carry from place to place during installation.Bending device can preform these aluminum, copper, steel.

device consists of 3 rollers placed on the frame.The pipe extends pivot roller, also known as pressure, turn the handle.Hand tube bender second version (PG-2) has a perfect design.Cross-section through it has achieved up to 6x3 cm. However, the sequence and the same principle of the previous device.

This miracle of technology helps to bend the blanks even figured out a ring that seemed to be impossible.

devices cost about $ 700-800.

These two devices have received the greatest recognition of all roller benders.

How to calculate the curve and create a homemade tube bender

No matter how wonderful the aforementioned machines were not for them should be given a lot of money, so many gold pens come up with for their home-made machines for bending workpieces.Economical solution!

should be noted that to create them used a variety of tools.For example, creating such machines with electric drive, which is not inferior to the factory.And in some ways, it was even better.

must be remembered

1. Stand for machine tools is required to be resistant to heavy wear, it is recommended to use a metal channel attachment to the foundation.
2. Each turner will perform for you the shafts, working bodies of the machine.All the details you need to connect the bearings.For the shaft of the mechanism, you can select two gears: chain and gear.This pinion is used in car engines.Belt transmission is not reliable in loads and when it was observed overshoot belts.
3. That can be bent workpiece homemade machine is also equipped with a roller which is mounted on the metal parts by means of screws.
4. for bending workpieces drive can be manual, but also electric, but he needs some kind of cover that would be a defense mechanism in terms of security.

Homemade machines allow you to do a lot more twists section than the factory.Therefore, by making itself a home machine, you can bend and shaped pipes and round without any problems.A bent pipe will form the basis for your greenhouses, sheds, porch and any other fiction of your imagination.
