Track Idler Double Stations Circular Seam 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
Double station, welding at the same time.
Welding torch is fixed while the workpiece is rotating. Welding
position is horizontal.
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.
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.
Two welding torches are separately positioned by CNC. It can move
up and down, left and right and angled turn, to reach welding
The welding mode and welding specification can be preset, saved and
recalled. Via ouch man-machine interface, the parameter
modification and status alternation can be done conveniently.
The machine consists of motor-driven reducing speed power head,
fixture, conductive system, pneumatic loading and unloading system,
turnover mechanism, welding torch CNC positioning mechanism,
welding torch clamping&adjusting&oscillating mechanism,
electrical control system, welding power source and pneumatic
4.Torch Clamping&Adjustment&Pneumatic Lifting Mechanism
It adopts push-type wire feeding mode, to guarantee feeding
stability. Welding torch can be adjusted up - down, left -right and
angled turn. The fine adjustment of torch uses swallow tail shape
and adopts ball screw adjustment, with high accurate adjustment and
high positioning accuracy. The oscillating mechanism consists of
stepper motor, ball screw, linear guide rail, etc. It adopts closed
type structure, shielding the process from dust and spatters. Torch
oscillating frequency, oscillating scope, oscillating time, torch
lifting time, lifting distance, lifting numbers can be controlled
by CNC system.
