IDW In-Die Welding Technology
In-Die Welding (IDW) is an unique method of integrating a projection welding station for small elements like nuts or bolts into a stamping die to combine operations.
This technology is a milestone in the automation of the stamping processes in the Automotive Industry.
Advantages
Used in progressive, transfer and tandem presses, from 80 to 3800 ton.
Production time massively reduced (welding operation not affecting stamping process speed)
Welding up to 45 Strokes/minute
Welding several nuts/studs at the same time (2 or 4 nuts)
High flexibility on manufacturing allocation (on-wheels equipment)
Welding process on large-size and/or heavy parts much easier (no part manipulation required)
No special nut necessary
Possibilities
Fastner Welding
Nuts, studs,… From common standards to tailored designs.
Spot Welding
Spots, small assemblies and projection welding.
Projection Welding
Small assemblies and fast welding. n
Components
Welding Cabinet
It is a standard and portable welding cabinet that has inside the weld timers that give the powers to the welding heads. You can use a welding cabinet in any die or tool provided with OCON welding kits, independent from the type of fastener (bolt, nuts, spots,…). There are two versions:
Welding Cabinet with two weld timers inside (as shown in picture)
Welding Cabinet with four weld timers inside
You need as many weld timers as welding kits in the die. You can join welding cabinets to add weld timers to your application.
Feeder Cabinet
It feeds the fasteners to the shooting units in the die. It can feed up to 60 fasteners per minute. You can use the feeder with any die or tool provided with OCON welding kits but only for compatible fasteners. There are 2 versions:
Feeder with two channels: It works with two welding heads at the same time (both with the same type of fastener)
Feeder with 4 channels: It works with four welding heads at the same time (up to 2 different types of fasteners)
The feeders are customizable. Please ask for special applications.
Feeders and welding cabinets are under OCON standard communication protocols. You can join feeders and welding cabinets to configure any combination of welding processes (nuts, bolts and spots).
Welding Kit assembled In Die
Standard OCON Welding Kits for the integrated welding of nuts, studs, screws and any smaller element in tools and dies
The welding units are built into the die in position of the material flow. The elements to weld are charged from the feeding systems directly into our welding unit in welding position. The kits are connected by special Multiconnectors with the Welding Cabinet.
You can bring as many units as needed into a stamping die (up to 4 kits.)
