Automating Bushing Flare and Flatten Assembly

A Customized Solution

Recently, an automotive manufacturer reached out to Orbitform for a customized solution for their hood hinge assembly.  The product required several machines with different forming processes to complete the sub-assemblies.  While the processes included many of Orbitform’s standard processes, it also involved one of our lesser-known capabilities – bushing flare and flatten. 

 

Sequence of Operations

Leveraging our powerhead as a press, Orbitform completed the bushing flare and flatten in two locations with a multi-tool head.  The sequence of operation was as follows:

  • Operator load two parts
  • Powerhead advanced to flare out bushing
  • Powerhead tool rotated and advanced to flatten the bushing
  • 2-position slide advanced, bringing the second bushing directly under the tool
  • Powerhead advanced to flare out the second bushing
  • Powerhead tool rotated and advanced to flatten the second bushing
  • Slide retracted to operator load station

 

Dedicated Left and Right

Due to the nature of the automotive industry, parts consisted of right and left-handed orientation.  To help combat the confusion, Orbitform provided two machines – one dedicated to each side.  Leveraging a poka-yoke process, part presence detection was added to ensure the correct parts were loaded in the corresponding machine.  To prevent bad parts entering the field, each station included vision systems to check for completion of the process. 

 

Multiple Sizes, Multiple Parts

To help create a machine that could form multiple link sizes, we added a servo-z mechanism for programable height adjustments.  The addition allowed for a quick height adjustment through the touch of a button on the HMI display.  Each part had its own program that could be selected.  The operator would select the part on the touchscreen and the proper program would form the parts.

 

The Final Solution

Upon completion, the customer was given a machine with two powerheads on one common base capable of forming four bushings in one cycle.  The unique system could achieve volume requirements while leveraging only one operator, thus increasing throughput.
