A tool changing process in presses used to mold automobile body parts has been automated.
The presses concerned are typical down-acting, hydraulic presses, as used in many industries. These presses are equipped with sliding tables that hold the tool in position and allow it to be changed automatically.
Automatic checking is required to ensure that both tool halves are correctly positioned on the sliding table as they are being prepared. Incorrect tool position, or absence of tool, can cause damage or failure.
The C44 inductive sensor (Classics family, Basic range) meets the requirements of this application, due to its robust industrial construction, flexibility and the proven reliability of its sensing capabilities in the required range (15 to 40 mm).
A sensor is installed on one corner of the sliding table and adjusted to confirm the presence of a correctly positioned tool. The accuracy in switching distance of this sensor means that any deviation in tool position is detected. An incorrectly positioned tool will therefore immediately trigger a process stop. This position/absence check takes place with all the speed expected from an automated factory process.
By preventing the presses from proceeding to the molding process with incorrectly positioned or absent tools, this automatic tool change sensor helps prevent production faults, reduce downtime and avoid damage to the presses themselves.
