Stainless Steel Cnc Pipe Bending Machine For Mass Production And High Precision

XEM series 3D CNC tube bending machine is a fully electric driven multifunctional 3D

CNC tube bending machine with left and right coexistence.

It has a high rigidity mechanical structure design and precision process level in accordance

with the principle of dynamic mechanics. With structural strength, the simple bending hand

and bending head design provide the largest bending space,

which minimizes the interference range of the machine. With the automatic program control system,

it can ensure that all types of steel tube bending work with high difficulty can easily meet the

dual requirements of mass production and high precision.

The powerful electric booster is a high-end model specially developed for high-tech bending needs.

Its special feeder mechanism is combined with a patented speed-changing structure to push the

bent pipes directly and forcefully.

Combined with the precise computer automatic tracking bending speed function,

it can easily perform extreme bending conditions that cannot be achieved by general standard models,

such as extremely small bending radius, thinner pipes or thicker pipes.

The upper and lower symmetrical multi-layer mold design can install left and right molds

with various different radii for automatic mold change for bending work,

overcoming the interference problem of single-direction rotating head processing.

It can clamp and process complex workpieces with high difficulty

such as left and right symmetry at one time,

greatly improving the accuracy and convenience of pipe bending processing.

The automatic mold change adopts the principle of up and down displacement and left and

right displacement of the machine head plus the rotation of the machine head to avoid the

shaking of the pipe caused by the displacement of the feeding seat clamp.

It has 11 axes electric servo drive: Y (feeding), B (tube rotation), C (tube bending),

Z (machine head left and right movement), D (machine head lifting and moving),

X (machine head rotation), F1 (main clamp clamping), F2 (auxiliary clamp clamping),

A1 (auxiliary push right), A2 auxiliary push left, and G (core pulling).

The C-axis (bending tube) adopts the original imported robot-specific RV reducer

plus servo drive transmission design. It has the advantages of simple head, deep throat,

small bending interference, high rigidity, long service life, high precision, high output power,

energy saving and good controllability.

The design of the machine head has been analyzed through dynamic mechanics.

The machine head has an integrated structure, high rigidity, and is firm and stable.

It does not shake during operation and can easily ensure high bending accuracy.

The quick mold-changing design provides more flexible production requirements

and can significantly reduce the mold-changing adjustment time and difficulty.

All circuit signal lines and electrical assemblies use modular plugs and are numbered for

easy replacement and maintenance.

It has a slow retraction function. The retraction time after the pipe is inserted into the pipe is

set according to the program. This can avoid the protrusion of the pipe appearance caused

by the fixed position of the pipe inserted into the pipe,

thereby improving the appearance quality of the pipe fittings.

It has a standard guide die auxiliary push device and is designed with pressure and

speed adjustment knobs, which can be easily adjusted to meet the needs of bending pipes,

making difficult bending work a breeze.

Advantech Taiwan Industrial Computer IPC BASE Controller PPC-1150

15-inch color touch screen.

The voltage is stable and the removable control console is convenient for the operator to use.

Operating system: Copyrighted professional version of WINDOWS 7 operating system.

Authorized by Microsoft to produce embedded systems.

The operation is simple and easy to learn by adopting WINDOWS dialogue icon guidance method,

and the program input method is concise and systematic.

It has intelligent pipe characteristics learning function before bending.

1. Take a three-material long sample tube and automatically bend it six times on the machine.

2. Use a special measuring tool to take six bends on the sample tube to obtain 6 data.

3. Input the 6 data into the machine controller for automatic calculation of the rebound characteristics

of this batch of pipes and use it as the basis for correcting the bending program.

4. At this time, if you input the data and actually place the tube for proofing,

you can bend out a very similar sample in one go.

The maximum bending program memory capacity is 2 million groups,

and each group can program up to 30 bends.

The operation program and pipe bending program can be stored in memory for an unlimited time,

and the program will not be lost due to power failure or long-term non-use.

The program and data are equipped with a user password setting function.

In addition to protecting the data from arbitrary changes by others,

each data modification can be traced back to facilitate data management.

While the machine is performing automatic processing,

the controller can still be used to input or edit programs.

It has XYZ coordinate value and processing value YBC bending pipe processing value input and

mutual conversion function, which is convenient for operators to use. After the program is input,

the front end length of the full length of the pipe can be automatically calculated.

The program has a mirror function, which can quickly obtain the symmetrical shape program

of each set of bending programs.

The program has a reverse function and can be quickly changed to the program

at the other end of the bend.

After the bending program is written, you can view the 3D simulation bending forming diagram of the pipe,

and you can touch the rotation direction and zoom function to verify the accuracy.

It has a 3D reading function and can directly convert the 3D image into STP format and

then into YBC program.

When editing a program, the user can input the correction value for the sub-program,

so that the original processing data will not be lost after multiple program corrections during proofing.

The bending process steps can be set independently, and the axis can be set to 10 speeds from 0 to 9,

so that it can be used flexibly for different workpieces to improve work efficiency.

There is also an external speed knob to reduce or increase the processing speed at any time as needed.

When in automatic operation, it has two functions: rear pulling and reciprocating feeding,

which can be switched to meet the processing needs of different pipe fittings.

The screen is equipped with tools such as calculator, trigonometric function calculation,

and curved length calculation functions for easy use.

According to the different rebound characteristics of pipe fittings,

two bends can be tested in advance to obtain the average rebound value,

and the rebound compensation value of each bend in the bending process can be automatically adjusted.

According to the different elongation characteristics of pipes,

two bends can be tested in advance to obtain the average elongation value,

and the elongation compensation value of each bend in the bending process can be automatically adjusted.

Equipped with metric/imperial switching editing function,

it is convenient for program input and reduces conversion time.

Adopting the absolute origin system, the machine can immediately enter the working

standby state without complicated operations to find the origin of each axis after restarting.

When starting the machine, there is no need to end the program

according to the WINDOWS mode program,

just turn on and off the power directly,

which is convenient and in line with the operating habits of general workers.

The screen synchronously displays the position status of each motion axis of the machine

and the change of bending angle.

Up to 10 file combinations can be pre-selected, and up to four sets of workpiece programs

can be automatically set for simultaneous production in sequence and set quantity,

providing high production flexibility.

If a problem or error occurs during automatic processing, the machine will be suspended.

After the problem is eliminated, the machine can be allowed to continue to

complete the unfinished work on the pipe, thus avoiding waste of pipes.

It has the function of automatic position self-checking of the Y-axis (feeding).

After setting the inspection accuracy, it can check at any time during automatic processing

whether the Y-axis is deviated due to the extension of different pipes,

so as to timely discover the size-unqualified products in batch production.

With the function of synchronous movement of the Y (feeding) axis and the C (bending) axis,

the Y axis automatically tracks the bending arc length of the C axis and cooperates

with the set tube elongation rate to avoid pulling of the tube during bending and improve accuracy.

The control program has the function of automatic error detection and text display.

Messages of machine failure or illogical operation are directly displayed on the screen,

with instructions for repair methods to prevent human operating errors from damaging

the machine and reduce the difficulty of maintenance. The above-mentioned abnormal

warning messages are automatically stored in the machine computer for future maintenance reference.

Automatic or manual time tool mode setting function can be set according to the nature of the work,

a variety of different working modes such as with or without threading, auxiliary push,

single step execution and other different states to improve production efficiency.

With multiple delay parameter settings, the most appropriate time difference setting

can be made for each action axis to meet various bending change requirements.
