Track Idler Single Station Welding Machine
1.Main Technical Requirement.
The material of rim is 35#, quenching and high temperature
tempering(HB167~235). The appearance and size must meet the
requirement, not allowed to have undercut, welding tumor, arc
crater, burn through, collapse, surface pores, surface cracks and
other defects in the appearance. The interior of welding seam
should not have the defects of slag inclusion, air hole,
non-through welding, non-fusion and internal cracks.
Complete the automatic welding requirements for the assembly of
track idler. The workpiece needs spot welding in advance. It needs
stable and continuous welding process, convenient clamping and
Welding torch is fixed, while the workpiece is rotating. Welding
position is horizontal.
The machine has high voltage and slow wire feeding performance,
which guarantees reliable arc igniting. Machine also has low
welding voltage and low current for filling crater.
Pneumatic loading and unloading mode, turn the workpiece 180°. The
process of welding is finished automatically. Reduce the labor
intensity of workers.
PLC is used to control the whole machine operation, the rotation
speed of the workpiece is controlled by AC frequency regulator,
stepless adjustment, improve the reliability of machine.
The welding mode and welding specification can be preset, saved and
recalled. Via touch man-machine interface, the parameter
modification and status alternation can be done conveniently.
3.Electric Control System
|rotation speed||0.2-2r.p.m. stepless adjustment|
|Welding Torch Adjustment|
|dip angle||25°~ 60°|
|welding voltage||15-36v. stepless adjustment|
|welding current||50-500A, 60% duty cycle|
|welding wire diameter||Φ0.8--Φ1.6MM|
Using OMRON PLC as control core, control the implementation of the
welding program. Stable system, simple structure, easy maintenance.
Using 4-axis CNC control system to control left-right and up -down
positioning of two welding torches.
Workpiece rotation adopts Japan Omron 1.5kw inverter. The rotation
speed is adjusted by controlling driver to adjust motor speed.
Stepless adjustment, low failure rate, suitable for long time use.
Taiwan Wei Lun MT-6070I 7- inch touch screen as the input and
output interface, offer modifiable initial account and password.
Welding length, arc igniting, arc ending time, welding current,
welding voltage, welding speed, preheating time, oscillating
frequency, oscillating scope, oscillating time, torch lifting time,
torch lifting distance, torch lifting times can be all input
through the interface.
Rotary closed-loop encoder will detect welding length. Position
detection: torch position is detected by imported non-contact
Integrated control panel box. Control button, touch screen, welding
specification are in one panel, easy to be used and operated.
