Efficient die change

Where forming presses and punches are at work , the entire process chain is trimmed for maximum output . But with decreasing batch sizes , the number of interruptions due to die or mould changes is increasing . A way to how to handle these efficiently will be shown by Roemheld at Stand K65 in Hall 27 at the EuroBLECH sheet metal exhibition in Hanover , Germany , from 25-28 October 2022 . The manufacturer is a market specialist in dieclamping technology for sheet metal forming .
“ Consistently high productivity is enabled by individual complete systems for efficient die change . A new feature is a pull-push system that moves dies weighing up to 50t in and out of the press via a chain drive . It is screwed directly to the press bed , where the chain transports the die at a speed of 33mm / s . Faster versions with a maximum of 200mm / s are also available . A separate guide is usually not required . The system is supplied without control as standard ; the control is available as an option ,” explained Roemheld .
There are different versions for different spatial situations in the press . If the press bed is high enough , the chain is mounted hanging downwards in the storage unit . Since the chain box is open at the bottom , it is also insensitive to dirt . However , if the press bed height is too low to store the chain , magazine storage is available where the chain is stored in a spiral . The system offers additional flexibility because it can be mounted in front of , or behind , the press bed or on mobile consoles .
“ The new pull-push system fits seamlessly into a comprehensive range of complete solutions for die or mould changes on punching and forming lines . Our extensive product range allows us to offer a complete solution for almost every situation . It starts with the rack systems . Using different types , they can be adapted to the respective requirements of the production site . Ball or roller bars in the racks and changing carts , as well as in the transport consoles , ensure consistently safe , quick and efficient die change ,” continued Roemheld .
“ The changing carts transport the dies between the storage area and the press . There , employees can bring them into the machine using consoles . Using a uniform docking system for all racks , changing carts and consoles , the dies can only be moved when all components are safely coupled . This significantly increases safety for employees during handling ,” it added .
Solutions for the positioning , centring and clamping of dies complete Roemheld ’ s overall concept . The clamping systems are available in mechanical , hydraulic , magnetic and electromechanical versions .
“ The die-change process becomes particularly efficient when using magnetic clamping technology . Clamping takes just a few seconds ; operators no longer have to intervene manually . Magnetic clamping plates are suitable for all ferromagnetic dies , regardless of geometry , size and dimensions . Standardisation is not necessary ,” concluded the manufacturer . n
