This automotive blank detacker was installed in January 2021 in North America for an automotive OEM. Variegate, Inc.’s Application Engineer collected the pertinent information from the OEM. With AP & T’s engineering and service groups this successful project was completed on time and in a three week installation window.
This blank destacker consists of a two destacking stations to provide continuous running capability. It scans the blanks and the SpeedFeeders (linear robots) adjusts the orientation of the blanks on the fly to present them to the presses’ servo transfer in the correct orientation. Automatic tool change and few moving parts, as compared to traditional destackers, are other features of this line.
The line is designed to run at approximately 25 spm running single blanks and tailor welded steel blanks. The blank stack alignment is aided by a programmable laser alignment system. Each servo driven linear robot has an up time of 98%.
Automotive Destacker with Automatic Tool Change
This coil fed servo transfer line is located in Cusseta, AL and was a 2013 installation to manufacture automotive parts. Variegate, Inc. provided the feed line and the two monobar servo transfers and a servo shuttle. This line can be run as a nine-press transfer or any combination less than nine presses. It can run as two separate servo transfers (five-press and four-press) or as a five-press servo transfer with four hand-fed presses. The line speed is being held down due to the controls on the presses not being capable of synchronizing with the servo transfers. Another one to two strokes per minute would be achieved with upgraded press controls. This line runs 24/7.
Metal Form Magazine ran a front page article on this line in their September 1, 2031 issue. Here is the link: https://www.metalformingmagazine.com/article/?/stamping-presses/transfer/walking-beam-transfer-line-epitomizes-flexibility-
In 2019 this 42″ wide servo feed line for high strength material was installed in TN. The customer won a contract for steel their existing feed line could not run. Variegate, Inc. spoke to their owner, plant manager and maintenance manager to determine the required specifications.
This lines maximum capacity, with 70,000 psi yield steel at 42” width, is 0.145” thick material. The minimum thickness is 0.030”. This line has been running this material successfully since early 2019.
In 2012 a Tier 2 automotive manufacturer, located in TN, purchased this gibb guided hydraulic press. It is used for calibration of lower bracket of a strut body of a shock absorber.
This 95 ton hydraulic hemming press was installed in 2013 in South Carolina for a Tier 1 automotive supplier. It had a few custom features requested by the customer which included a Siemens safety PLC and custom bolster machining.
