Rotary Punch Chopping and Marking
Patented Rotary Punch Chopping and Marking System
Cuts continuously moving flat strip without stopping it, using twin-drum rotary die technology, and stamps the weight and logo on it. Works with zero scrap.
Rotary Punch Chopping & Marking: Engineering Architecture
At the heart of the wheel weight line, the patented press-less Rotary Punch Chopping Machine removes the vibration and speed limits of conventional stop-and-go presses and processes the continuously moving metal strip with a non-stop rotary die motion.
Press-Less Continuous Rotary Punch Mechanism
With conventional guillotine and eccentric press cutting, the metal strip has to stop at every stroke; with Rotary Punch technology, the rotating punch drums move at the same speed as the material. Driven by a 3 kW AC motor and a variable-speed AC drive, the drums divide the moving flat strip into weight segments without stopping it.
The continuous circular motion eliminates the impact and shock of press lines and gives energy savings of up to 80% compared with conventional press lines.
Weight Precision & Zero-Scrap Cutting
The die geometry produces no chips or edge scrap during cutting; because the cut weights are burr-free, no separate deburring step is needed. The weights are cut within ±0.5 gram tolerance on a 60 g strip.
The completely scrap-free (0%) working principle gets the maximum yield from the raw material.
Simultaneous Marking & Die Material
At the same time as cutting, the marking drums cold-stamp the company's brand logo in the centre of the weights and the "Fe" mark and the 5 / 10 gram value at the corners. No separate marking station is needed, which shortens the line.
The cutting blades are made of 1.2379 (D2) cold-work tool steel and the marking drums of Vanadis 4E steel. The machine uses only 1.37 kWh of energy per 100,000 pieces.
Technological Advantages & Innovation
- Capacity of 60,000 pieces per hour with a continuously rotating twin-drum die design
- Continuous cutting principle that, unlike guillotine cutting, does not require the material to stop
- Simultaneous cold stamping of the brand logo, the "Fe" mark and the weight (5 / 10)
- Burr-free cutting means no separate deburring step is needed; scrap-free production
- Energy consumption of only 1.37 kWh per 100,000 pieces
- Easy setup with Delta PLC and 7" touch HMI
