Roll senors bring economic advantages
- Better productivity due to higher drawing speeds in normal production
- High degree of reliability - low downtime
- Much better finish wire quality due to a gentler handling of the wire during the drawing process (less wire deviations, no torsion etc.) as well as an optimised wire cooling
- Easy operation
- Better environmental conditions due to increased dust protection, air cooling required only for large diameter high carbon wires
- Greater flexibility and lower current consumption due to modern drive technology
- Lower noise level compared to older type machines
Optional features
- Foot pedals for inching operation
- First block in combination sensor roll/OTO design
- Last block designed as finishing capstan
- Rotary die holder for specific resp. all blocks
- Quick die change cassettes
- Pressure die systems
- Soap boxes with stirrers
- Environmental guarding system
- Special cast killing systems for speciality products, e.g. bead wire
- Cooling water flow/temperature control units
- Very flexible - same control system from wire dia. 0,2 to 16 mm at all drawing speeds
- Avoids uncontrolled back-pull
- Straight wire path
- Self-regulating and -correcting
- Easy to string-up
- Fewer moving parts
- Low maintenance
- Optimum cooling effect which increases with the speed
- Self-cleaning, maintains consistent cooling over time
- Can use coarse filtered industrial water in wide temperature range, up to 35 ºC
- No rotating seals
Pneumatic, high speed brake system
- Normal stop:
- under ramp down control within 15 - 30 sec.
- Quick stop (wire break):
- brakes under control, stop in 3 - 5 sec. without additional wire breaks
- Emergency stop:
- machine in 1 sec., spooler/coiler in 1 - 3 sec.
- Special design of last die box, with scale, for fine setting of cast and helix
- Opening for vacuum hose at every die
- Vibration dampening devices at high speed blocks
Drawing capstan
- Various block coating systems available, depending on the wire material to be drawn.
Includes coatings e.g. ceramic, CDS "continuous detonation system", conventional plasma spray etc.
- Third generation computer system (more than 400 computer controlled KOCH machines in operation)
- Continuous color graphic display of important operating data such as speed, die status and spool/coil status
- Operator friendly interface for all machine operational and control functions
- Easy trouble shooting
- Interface for data acquisition
- Upware compatible - easy future upgrades through software
Frequency controlled A.C.-drive
- Transistor controlled A.C./A.C. converter
- Controlled by means of the pulse width modulation system (P.W.M.)
- Constant power factor (cos.phi) of better than 0,95 at all speeds and load conditions
- Digital and microprocessor controlled
- No need of compensation and low harmonic feedback to the net
- Readout display
- Interfacing for data acquisition
- One communication cable replaces hundreds of control wires
- Significant saving of cost and time in the installation of the machine
- Simpler wiring system reduces problems and simplifies trouble shooting
- Allows data acquisition and remote trouble shooting of the control system and drives
- Most details system analysis through bus system, down to drive details
- Remote connection through modem allows on-line trouble shooting by KOCH engineers
- Easy software update by modem
- Unique KOCH technology, highly reliable
- Utmost control flexibility, allows any drafting program and block skipping
- Not affected by outside factors such as temperature and electrical interference
- No potentiometers
- No aging phenomena
Various further options available, as for example:
Rotating die holder for specific resp. all blocks
