Electronic Screwdrivers

With transducer- Twin control of feed torque and detected

ACE screwdrivers feature complete programming of all stages of the screw driving process. Approach speed, pre-assembly speed and torque, final torque and tightening angle can all be programmed.

Screwdrivers with a built-in transducer have a screw driving torque precision of +/- 1% of the scale range (e.g. a 80 Nm screwdriver has a precision of +/- 0.8 Nm); torque precision is independent of the maximum torque requested.

The repeatability precision when screw driving rigid fastenings is 1% for the transducer version and 3% for the versions without transducer.
To obtain the best results the screw driving units should be secured using suitable clamping systems.
The ACE screw driving units have a single screw driving spindle and a controller unit for each spindle.

Technical data:

– Graphics LCD display with 4 lines of 20 characters each line. Built-in membrane keyboard. Up to 5 screw driving programs of 5 steps each can be set, stored and called up from the keyboard.
Each program step can be programmed by the user as required with the following values:

i. Speed / Direction of rotation
ii. Torque or Angle to be reached
iii. Time limit or degree limit range within which the set torque/angle must be reached.
– Up to 1024 screw driving operations can be stored to memory.
– Torque curve of the last screw driving (resolution 0.01 seconds) can be stored to memory.
– RS-232 C connection to PC for reading screw driving data on-line
– RS-232 C connection to PC for transferring memory data.

Options available:

a. Data concentrator. This provides a single interface for a PC and enables the downloading of all data with a single signal.
In this case each data item is complete with the number of the spindle to which it refers.
b. Function for setting the number of screw driving operations per cycle. The operator can use this function to set the number of screw driving operations per cycle. When the set number of screw drivings is reached, the controller gives the “Cycle completed” signal and enables the start of the next cycle.
Example: You want to fix a flange with six screws. The controller can be set to give the “cycle completed” signal after 6 screw driving operations without triggering an alarm.
c. Expansion for memory cards
d. Customisation to users specifications.

Electrical screw driving unit – “COSMO”

The AVEL screw driving unit controls screw driving speed, the maximum tool torque and the preset torque value.
The screw driving speed can be instantaneous or reached after a preset acceleration ramp.

The new COSMO 100 electronic control unit is able to operate according to 7 screwing methods:

1. SIMPLE TORQUE SCREWING: the screwdriver stops as soon as the pre-set torque has been reached – constant speed.
2. SIMPLE STROKE SCREWING: the screwdriver stops as soon as the pre-set number of revolutions has been reached – constant speed
3. TORQUE SCREWING WITH SPEED CHANGE AT INTERMEDIATE TORQUE: it screws at a constant speed until a pre-set torque value, then changes its speed and stops as soon as the end tightening torque has been reached.
4. TORQUE SCREWING WITH SPEED CHANGE AFTER NO. OF REVOLUTIONS: it screws at a constant speed for a pre-set number of revolutions, then changes its speed and stops as soon as the end tightening torque has been reached.
5. TORQUE SCREWING AND FOLLOWING ADDITIONAL ANGLE: as soon as a pre-set torque value has been reached, the screwdriver turns another pre-set angle and then stops.
6. TORQUE SCREWING, DEG- ANGLE UNSCREWING AND FOLLOWING ADDITIONAL DEG+ ANGLE SCREWING: as soon as a set torque value has been reached, the screwdriver stops, unscrews by a pre-set angle and screws again by a pre-set angle, then stops.
7. C1 TORQUE SCREWING, DEG- ANGLE UNSCREWING AND FOLLOWING C2 TORQUE SCREWING: as soon as a pre-set torque value has been reached, the screwdriver stops, unscrews by a pre-set angle and screws again until a new set torque has been reached.

FOR EACH SCREWING METHOD IT IS POSSIBLE TO SAVE THREE DIFFERENT SERIES OF CHARACTERISTIC PARAMETERS.

> TORQUE PRECISION:
– VERSION WITH PREPARATION TO MANAGE THE EXTERNAL “TORQUE METER” TRANSDUCER: ± 1%*
– VERSION WITHOUT DISPOSITION TO MANAGE THE EXTERNAL “TORQUE METER” TRANSDUCER: ± 3%*
* = of the full scale of the maximum guaranteed reachable torque

> THE CONTROL UNIT IS PREPARED FOR THE CONNECTION TO THE PLC FOR:

Customised programming
Adjustment and printing of single tightening parameter values

> CONNECTING CABLE m 2
