THE ELECTRONIC THREAD TAPPING UNIT, SPECIALLY DESIGNED FOR PUNCHING AND FORMING PROCESSES, FEATURES

EXCELLENT PROCESS INTEGRATION. WHETHER THE ELECTRONIC THREAD TAPPING UNIT IS USED IN FOLLOW-ON OR

COMPOUND TOOLS, IN PRESSES OR IN AUTOMATIC PUNCHING AND BENDING MACHINES, THE REQUIRED THREADS ARE

CREATED IN A RELIABLE AND CONTROLLED MANNER. THIS IMPROVES THREAD QUALITY, INCREASES PROCESS RELIABILITY

AND ENSURES FAST, COST-EFFECTIVE PRODUCTION.

Schematics of torque monitoring:

During thread forming, a measurement takes place every 1 ms, and the value is compared with the case graph.

For each thread a separate data record is created, which can be monitored if necessary.

QUALITY

The thread tapping unit produces high quality threads in sizes

M0.8 – M24. The thread shapes are characterized by:

▬ great strength and stability

▬ high surface quality

Using the auto teach function, the system fully automatically

determines and monitors the optimized parameters for the

respective process. In the event of a deviation in the parameters,

for example in the event of tool breakage, tool wear or

deviations of the core hole, even highly dynamic processes are

stopped in fractions of a second and the forming tool

automatically moves out of the danger zone to a safe position.

All data records can be exported and summarized in a QA

report.

COST EFFECTIVENESS

In addition to producing high quality threads, the cost-

effectiveness of the thread tapping process is above all

efficient.

Cost savings can be achieved via:

▬ long service life of the tools

▬ faster processing times

▬ avoiding rejects

▬ eliminating the feeding of parts and additional production

stages

▬ Reusability of the drive and control components for multiple

tools

THE SERVO DRIVE

The servo drive consists of one synchronous servo motor

which offers flexible usage options in single or multiple applica-

tions. This makes it possible to produce different thread sizes

in one tool using one control and one motor. Thanks to the

constant cutting speed, significantly longer service life dura-

tions are achieved than is the case with mechanical, positive

control systems. The drive is independent from the press

stroke and press motion.

FLEXIBILITY

Using a movable articulated shaft, the system can also be

utilized in positions that are difficult to access and at unusual

angles. The forming head of the unit is mounted directly into

the respective tool. Regardless of whether a multiple head or a

head with internal lubrication is used, or whether a single or a

double gearbox is to be connected upstream, the servo motor

and the corresponding control always remain the same and

can be reused for any subsequent project.

THE CONTROL BOX

The control and servo regulator for the drives are housed in the

control cabinet. The size of the control cabinet varies according

to the number of systems that are to be controlled. The free

programming of the various parameters permit the control of dif-

ferent thread sizes (e.g. spindle speed, torque limitation, cycle

time and part volume).

This entire spectrum results in key torque monitoring data that

monitors every cycle step.

HIGH PERFORMANCE IN TIGHT SPACES

FIBRO has developed a miniature unit especially for the

smallest thread sizes – M0.8 to M3.5 – that corresponds to the

design and function of the large FETU unit, except that its

structure is considerably more compact. With a width of only

30 mm, the mini forming head can be integrated into even the

smallest tools.

THE BEVEL GEAR

The angular gear serves to limit the length of the installation

space required by the drive. Using the angular gear is optional.

THE DRIVE SHAFT

The articulated shaft transfers the torque from the drive to the

forming head. By evening out differences in height and length,

the forming head can be installed in any position within the

tool, and can also be moved on hold-down plates. Using an

articulated shaft is optional.
