and WIND-DC-CW003 get most repeated order among welding machine
|
(3) History of becoming star product:
The first two pcs welding machine WIND-DC-CW003’s user was a car
motor manufacturer who produce
motors and supply to BMW and Volvo, they used Italy and English
imported welding machine and WIND-
DC-CW003 worked as backup machine. After several months test user
found welding result and quality is
same as imported welding machine and ordered 1pc more three years
later.
High frequency inverter DC power supply is a trend in commutator
welding, some supplier said they use
high frequency actually they use 2KHz, while Wind Automation can
achieve 15KHz, with real and pure DC
power supply which achieve constant welding quality!
(4) Fusing machine Parameter:

(5) Feature:
1) Commutator spot welding machine conductor hot staking Fusing for
thin or big wire High frequency
inverter weld and hot stacking commutator with small big wire thin
and big wire, with separate
cooling water device (act as a conditioner)
2) Welding operation is related to the tungsten rod area, pressure, welding time, voltage current value
3) Armature OD, shaft size is related to the fixture
Armature OD normal range 20~60mm
Shaft below 160mm Shaft size
Fusing machine FAQ (How to select a suitable welding fusing hot
staking machine)
- Are each segment’s current and time adjustable?
Your question is about achieve even and constant fusing quality for
each segment,
The DC power supply machine with high requency's output current is
even and constant, can make sure even welding quality,
On machine parameter set screen, there is 6sections welding current
and time setting for armature with many hooks such as 63hooks,
and for a 24 hook commutator, you can divide the welding parameter
to 3 stages by setting Bar. no. as 1+22+1 = 24 or divide the
setting to set 1+1+1+2+3+16 =24
considering heat up time for electro rod and actual situation,
In actual production, some user just set the Bar No. in Section1 as
24,
2. How electrode distance is controlled?
The distance suggested is about 1.5mm to 2mm, should be more than
1mm in case the commutator OD have some difference
You can check by a 1.5mm thickness commidity as a
3. How the pressure applied by the electrode to the hook is
adjusted and controlled?
With diffent size of Press Spring the pressure can be adjusted, for
rough control with spring,
for slight control with screw on top
4.Is there any load cell to control this pressure?
Yes,
Our hydraulic and servo press machine for commutator, shaft
placement have this kind of load cell which can control and show
pressure,
We are applying this to the new fusing machine with servo device
pressure later,
This will be applied for local motor manufacturer who required
first
5. What are the steps of the fusing cycle, how each portion of this
cycle is adjusted?
Fusing cycle is electrode touch the commutator hook, then press the
commutator hook, holding the pressure and release
Please check graphic of the fusing cycle on welding setting photo
This cycle is related to four factors,
the electrode and commutator hook contacting face area,
pressure value, holding the pressure time, fusing voltage
You can get a best cycle by teamwork of this four factors,
High frequency 15KHz ensure the pure output DC current, while some
fusing machine 2KHz, 4KHz not high frequency
The constant current can make sure fusing each segment without
hesitate, so DC power supply is faster and save electricity
6. Is there any warning sign for bad fusing?
Yes, machine have this function
