Useful instructions for copper pipe bending

Here is another interesting article we found, about how to use a copper pipe bender; there are many commonly used applications which require bending the copper pipe, such as heating, plumbing, air conditioning, etc.

These kind of bending machine allow the user to manually bend pipe to the required angle to connect to the system fixtures.

Copper pipe will straighten slightly after being removed from the copper tube bender. It is advised to bend the pipe about 2 to 5 degrees more than the desired angle. It wikk take some practice to get familiar with this process and correctly judge the extra bend angle to use.

Bending Machines Operator

A bending machine operator sets up and operates machinery constructed to bend metal structural shapes, such as pipes, tubes, bars, rods, angles, to angle or contour according to speficic requirements such as drawings, templates, or layouts: the operator selects and bolts holding clamp, die block, and guide clamp to machine.
Following, are some of the activities due during the daily operations:

• Positioning and clamping end stops on machine to set specified location of bend.


• Screwing or insterting or plug stops into guide wheel to set specified degree of bend.


• Positioning workpiece against end stop. Locking and holding clamp and guide clamp onto workpiece.


• Lubricating workpiece with oil.


• Starting turntable to draw workpiece through guide clamp around die block until stopped by plug stops or until dial indicator points to specified degree of bend.
• Sliding mandrel into tubing instead of using guide clamp.


• Etc

Being the bending industry quite big, it can be easy to find several open positions for this kind, despite this industry has been challenged as many others by the struggling faced this year by western countries economies.

Bending Performance Evaluation

I found this interesting document and I would like to share it with you:
square tube bending performances of aluminum beams reinforced by aluminum plates under three point bending loads have been evaluated using experimental tests combined with theoretical and finite element analyses.
Basic properties of aluminum materials used for initial input data of the finite element simulation were obtained from the true stress-true strain curves of specimens which had bean extracted from the Al tube beams.
True stresses were determined from applied loads and cross-sectional area records of a tensile specimen with a rectangular cross-section by real-time photographing. True strains were obtained from in-situ local elongation measurements of the specimen gage portion by the multi-point scanning laser extensometer. Four kinds of aluminum tube beam specimens adhered by aluminum plates were employed. The bending deformation behaviors up to the maximum load described by the numerical simulation were in good agreement with experimental ones. An aluminum tube beam strengthened by aluminum plate on the upper web showed an excellent bending capability

How to Work on Bending Machines & Press Brakes

I found this interesting article on eHow.com with some step by step instructions on how to operate press brake bending machines risk-free, since they are designed to bend metal using tremendous amounts of pressure.

Here is a summary of the instructions to take care of your bending machines:

• Ensure that the machine is not in repair and is in ready working order.
• Clear the machine of any foreign objects before applying power. Adjust the machine to best fit your ergonomics.
• Wear all required protective gear and use all required safety equipment. If safety equipment is required and is not available, do not use the machine.
• Operate the machine according to use and not for ease.

EuroBLECH 2010: Sheet metal working industry prepares for the uptrend:

EuroBLECH 2010 shows latest trends and innovative technology From 26-30 October 2010, the 21st International Sheet Metal Working Technology Exhibition
will open its doors again in Hanover, Germany.
This year, the world’s largest trade exhibition for this industry sector will focus upon innovative technologies for the future of sheet metal working.
Enhanced fabrication processes for adapting to changing demand; intelligent
systems and machines for energy-saving and environmentally sustainable production; new materials as well as the latest trends in R&D will be on display.
“The current situation, a period of economic regeneration, demands a great deal of
innovative capacity from every company. After a difficult time, it is important to now set the course for the future by sourcing the right equipment,” explains Nicola Hamann, Exhibition Director EuroBLECH on behalf of the organisers, Mack Brooks Exhibitions. “For industry experts from all over the world, EuroBLECH 2010, with its theme ‘Time for Innovation’, is therefore the first choice when it comes to gaining a comprehensive overview of trends and innovative technology, and to finding suitable machinery and tailor-made solutions”, says Nicola Hamann.

With 1,410 exhibitors from 42 countries and a net exhibition space of 78,000 m2 this year’s EuroBLECH is bigger than the show in 2006, a very successful year for the sheet metal working industry.
“Although this year’s figures do not match the record exhibition in 2008, the
current booking status clearly shows that the sheet metal working industry is on the up again”, says Nicola Hamann.
International participation at this year’s EuroBLECH has risen again slightly, with 46% of exhibitors coming from outside Germany this time. Following Germany and Italy, Turkey now represents the third biggest group of exhibitors. The number of exhibitors from Asia, particularly from China, Taiwan and India, has also increased substantially for this year’s show.
Traditionally EuroBLECH is also a highly international event as regards the visitor numbers. At the last exhibition, 35% of the trade visitors came to Hanover from abroad. A total of 69,400 visitors from 98 countries attended the EuroBLECH 2008 show.

A Guide to Cnc Tube Bending Machines

Do you know about CNC tube bending machines? These are designed in a fashion to minimize the time of set up and to maximize production. The CNC tube bending machines are available with many companies. Some of the companies have also launched CNC tube bending machines that feature electrical servo-drives on all axes and these are available in single as well as multi stack versions.

CNC pipe bending machines with multistack benders facilitate complicated bending without the requirement of tool change. In case, you cannot apply a multistack tool for stability reasons, try to switch over to an automatic clamp die changing system that will easily accommodate up to eight clamp dies.

The tube CNC bending machines feature excellent bending procedures that are programmable and boosting via the transport carriage in conjunction with the boosting in the area of pressure die. The boosting tends to minimize wall thinning towards the outer bend that further facilitates narrow bending. You can easily achieve a radius of less than 1 x OD. Other important features of CNC tube bending machines include the following:

An MMI multicontrol 2020 system
TFT monitor
Touchscreen
Plausibility verification
XYZ coordinate recalculation into bending parameters
Flexible programming
Multitasking
3-D displays
Integrated modem
Access to the world wide web

The integrated modem and access to the internet works towards providing the best of remote maintenance and technology support.

The CNC tube bending machines has a bending template. This helps in bending the pipe as desired. The unbent portion of the pipe is supported on a pipe that supports rail carries. It is also adjustable in height. The adjustment of height can be easily done by a drive and it is best suited for step-less positioning. This easily sets the pipe-supporting rail to a height that is already specified by the CNC control unit. Before bending the pipe, the height to which the pipe has been moved, is determines via a functioning program that is dependent on a full set comprising of tool data that has been input into the control unit.

Here are the features specifications of a CNC tube bending machines:

Industrial PC control
I/O card machine control
Input of all program to industrial PC via touch screen
Input data of Y.B.C.
Input data according to Descartes X.Y.Z coordination to build bending parameter.
The profile of tube will display on the PC as per the built parameter or input data.
Servo-motor control that feeds axis-X as well as rotates Axis-B, and then bends Axis-C that’s derived via hydraulic pressure
Program transmits via flash disc, floppy disc or the World Wide Web.
Adopt windows XP Embed operation system.
Process of the function auto and manually
