Cold Forming with Minimized Changeover

New system uses servo motors to emphasize speed, flexibility, precision, and throughput.

HATEBUR is introducing a new cold forming machine for high-precision parts up to 130 mm long and 32 mm diameter. The COLDmatic CM 725 is a seven-station process machine recommended for automotive industry suppliers.

“Our engineering team implemented several innovations to make our clients more efficient and productive,” stated Reinhard Buehrer, who heads marketing and sales programs for the Swiss machinery developer. “With a production capacity of up to 180 parts per minute, the CM 725 is much faster than previous machine generations.”

In addition to process speed, the new Hatebur system minimizes the changeover times: At the wire in-feed, a linear servo-motor ensures that the grippers push the wire forward with exceptional precision.

“The volume variation of the cut-off parts is below 0.35%. Together with the high quality of the sheared surface, which is typical for the COLDmatic, this results in a cut-off quality that allows forming from the first station,” according to Buehrer.

The significant new aspect of this COLDmatic machine is the newly designed transfer-system on which the grippers for the part transfer are mounted: All grippers are individually driven by servo motors, and can be individually opened and closed as well as programmed. “This programmability brings enormous advantages when it comes to changeover times. Instead of changing all the parameters manually, all previously saved settings can be applied in just a few seconds,” Buehrer explained.

Because of the servo motors, the COLDmatic CM 725 uses many fewer mechanical parts than previous machines, reducing the overall costs by almost 20%. The fast changing system allows operators to lift out all seven punches and dies at once and exchange them with prepared units. All tools can be exchanged in only ten to fifteen minutes.
