ELECTRIC MOTOR SLEEVE PRESS

An electric motor sleeve press was needed that would decrease set up time and compensate for motor sleeves which were out of round.  The press was to be capable of communicating with a master file based on a part number and perform all its major setup’s automatically.  The basic machine was to be a hydraulic press.

In order to control press depths accurately an adjustable top stop was designed to be operated via servo and connected to a PLC.  A second stop was required for the bottom tooling here a stepper motor was used and a program written to interface with part data.  All motor parameters were entered via smart terminal and an onboard PLC.  Networking connected the system to the office computer and data base.

To correct sleeve out of round, tooling was designed to expand the sleeve back to round.  This was done by use of a 4-way valve and hydraulic cylinder.  Power for the cylinder was taped from the main press system.

Design changes to the staking tooling eliminated the need to stock multiple staking tools.  One tool now does the work for any  motor stack size.

Advantages realized are:  faster setups, less tooling to stock, ability to run out of round sleeves, result more production.
