Push-To-Fit electromechanical solution for press and joining applications

Parker introduces its flexible Push-To-Fit electromechanical solution for press and joining applications.

Combining a set of the company’s established and reliable core products including a controller, servo drive, motor and electro thrust cylinder connected together through software, Push-To-Fit is an energy efficient and cost-effective module. 

Aimed at general industrial assembly and in-plant automotive joining applications its modular construction allows fast and easy integration into customer processes.

Push-To-Fit is available with a choice of four different standard thrust forces of 9.3kN, 25.1kN, 56kN and 114kN, and defined standard travel lengths of between 100mm and 600mm – this makes it suitable for use in a wide range of applications. 

Repeatability of 0.03mm ensures precise joining and high travel speed up to 450mm/s give excellent throughput rates.

The hub of the solution is a process control unit that supports easy integration into existing plant networks and provides simple, convenient parametrizsation, visualisation and operation. 

The monitoring methods used ensures that real-time quality control is guaranteed. 

The process control unit is fully compatible with, and prepared for, third-party device connectivity with dual LAN networks and options for Profinet, Ethernet IP and Modbus. 

Numerous operating options such as web visualisation, digital I/Os and communications interfaces (for example, OPC UA) are available to facilitate integration.

Push-To-Fit is supplied with Safe Torque Off (STO) as standard, this brings a drive safely to a no-torque state. In addition, advanced functional safety is available with a safety PLC. Acting as a Fail Safe over EtherCAT (FSoE) master the safety PLC uses the EtherCAT fieldbus to establish safe communication between the safe I/O modules and the drive. Separate wiring is not necessary. T

he first expansion stage includes Safe Limited Speed (SLS) and Safe Brake Control/Safe Brake Test (SBC/SBT) for the internal motor holding brake. The second comprises an additional external safety brake with SBC/SBT up to performance level PLe.
