Home / Solutions / Automations for transfer presses
With more than 200 references in transfer presses, Fagor Arrasate has been supplying transfer presses for over 30 years, more than 20 of which have been spent manufacturing large transfer presses of over 3,500 tons. Our presses are fully automated upon delivery. We have our own automations that we have been developing for more than 20 years, such as transfer systems or pick-up destackers. In this way, at Fagor Arrasate we can offer our customers a 100% proprietary solution that guarantees optimal synchronization.
The automation process involves, in addition to the mechanical press itself and the electronic transfer, other electronic and mechanical components and accessories, such as loaders, clamps, software, as well as the dies and the auxiliary bar with the gripper and safety elements.
Press automation systems
Typically, the bottleneck of a transfer facility took place in the die and press, but it was rarely in automation. With the development of servo technology, the bottleneck may be in automation. Our CT Transversal destacker has been upgraded to run at up 40 spm with blanks of up to 80 kg.
In this case the Destacker is equipped with two feeders and two loading carts, which collect the blanks from the station and switch over to the second one when the first stack is finished. This process can be fully automated, without the need for manual labor. The concept of complete automation includes the loading of the blanks into the loader by means of AGV technology.
The transfer installations aim to meet the demands of component manufacture in a fully automated way and without the need for manpower to run the pieces through the successive dies that make up the piece. The heart of the installation is the transfer, which moves the pieces arts from one station to the next to perform the successive operations necessary for the shaping of the piece, with the press continuously working.
Our electronic transfers achieve the best dynamic performance possible, increasing the rate and improving productivity. These are light transfer developments, which seek to respond to our customers’ main concerns:
Fagor has 8 different models for different head dimensions and configurable and adjustable dies.
As our solution for servo presses, large racks spanning up to 8000 mm in length and for high productivity requirements, we have designed the “S” series.
All Fagor transfers are adaptable to the specific needs of our customers through a comprehensive options package:
There are many critical aspects to a transfer, but one of them is the automation system’s vibration level. To significantly reduce the vibration level of the transfer bar, Fagor Arrasate has developed the anti-vibration bar system. Thanks to this system, we have improved the transfer bars’ behavior making them much more stable.
Within the SYNCRO software, designed by FAGOR ARRASATE, we find the ideal tool to optimize the interference curves between press and transfer, as well as the support needed during the die design phase to avoid unwanted interference. The main advantages of our software’s application are:
SYNCRO optimizes the press stroke, calculates the press cycle and then adapts the transfer motion so that the piece can move without interfering with the press. The use of 3D software (such as Siemens PLS, Delmia, etc.) provides detailed information on the project and allows for constant checks and updates regarding its progress:
All this allows us to obtain the maximum press-transfer synchronism thereby achieving the highest processing speed. In addition, we offer transfer use training to our customers in order to achieve the highest productivity.
LRB1: One axis
LRB2: Two axes
To improve the efficiency of the transfer system, it is important to have a gripper system that securely and firmly fastens the piece and helps the transfer operate at maximum efficiency to ensure the best results in terms of productivity.
Our team of designers creates customized gripper systems optimized for our customers’ presses and dies.
Great design flexibility
At FAGOR ARRASATE we design customized clamping systems for our customers using components from leading brands. We offer great flexibility in design, covering a wide spectrum of sizes, materials and gripping technologies:
In order to increase the production capacity of the transfer facilities and improve the quality of the final product, at Fagor Arrasate we offer our customers a service of updating and modernization of the facilities, from the press to the automations, both in Fagor lines and in third party manufacturers’ lines, anywhere in the world. This service consists of:
