High performance 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. We have our own automations that we have been developing for more than 20 years, such as transfer systems or pick-up destackers.

Overall efficiency

At Fagor Arrasate, we can offer a 100% FAGOR ARRASATE solution, with a single control architecture for the entire line, optimizing all manufacturing and maintenance operations, taking up a minimum amount of space and ensuring better access to the various accessories of the installation. This ensures an optimal synchronization for the entire installation, resulting in higher productivity ratios and a user experience that is safe and simple.

One of the main requirements to ensure the optimal synchronization of the installation, thereby achieving higher productivity ratios, is to have a fully integrated HMI into the press.

Large transfer presses of up to 40,000 kN of force

The large transfer presses are capable of producing structural and chassis pieces from materials such as HSS and UHSS—establishing themselves as an alternative to small-medium size press lines—and even some hot stamping processes.

Stamping of thicker pieces, or of more demanding material, with higher yield strength (HSS or High Strength Steel).
Stamping of larger and more complex pieces.
Increased productivity and cost reduction:
- Increased availability thanks to reduced die changeover times.
- Reduced operating costs: dies, workshop size, pit, automation, etc.
- Reduced maintenance costs: reduction in the number of presses, hydraulic units, oils, clutch brakes, spare parts, robots, etc.

With more than 15 references of presses of over 30,000 kN, at Fagor Arrasate we have experience in the construction of structures capable of supporting the loads generated by these pieces and materials. Using the Finite Element Analysis (FEA) method, we are able to optimize large structures in each installation. The FEA method allows us to detect the areas of the press that endure the greatest stress, allowing us to reinforce said areas in the design phase without running into the problems caused by oversizing.

Electronic Transfer

The installation of an electronic transfer grants us the option to program and store a great variety of cyclograms, biaxis, triaxis, triaxis suction cups, crossbar, etc., thus adapting to the movements and operations required by the dies. This electronic transfer provides great flexibility to this installation, allowing it to manufacture a wide range of pieces. In addition, these are light transfer developments, which seek to respond to our customers’ main concerns:

More strokes per minute · Increased process safety and robustness · Improved efficiency and productivity · More flexibility

Maximum precision movements

Fagor has 8 different models for the differently sized installations and pieces to be manufactured. The main features are:

Maximum transfer rate of up to 70 spm
Maximum transfer weight capacity of up to 400 kg transfer capacity (piece + clamp).
Transfer bars can be made of aluminum or steel
Electrical and hydropneumatic design realized by means of 3D models
Minimum deviation
Maximum rigidity

These elements’ optimized design ensures a synchronized process with a positive effect on the system’s productivity. At Fagor Arrasate we offer services for an optimized design of all transfer system components.

Anti-vibration System

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.

SYNCRO: Production Optimization Software

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:

Advantages

Reduction of die and gripper system design and manufacturing times.
Reduction and streamlining of tests, in-plant checks and fine-tuning.
Optimized calculation of the maximum operating speed.
Improved productivity and reduced incidents.

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 provides detailed information on the project and makes it possible to constantly check and update its progress:

Processes

Checking and optimizing die design.
Checking and optimizing the design of the gripper elements.
Optimizing curves through collision checking and offline scheduling generation.
Optimizing curve overlap by increasing the rate.

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.

Automations

The transfer installations are characterized by a high degree of automation and high productivity. In addition to the mechanical press itself and the electronic transfer, this automation process involves other electronic and mechanical components and accessories (such as loaders, stackers, clamps, as well as production software, dies and safety elements):

Feeding line: The installation can be fed by packs of blanks or by coil through a coil feeding line, where the web can be fed directly to the die or through blanks via a straight or oscillating shear.
Automatic tool change: We have fully automated systems that allow us to drastically reduce the time required to switch tools. This eliminates downtime and errors during manual processes.
Operator assistance system: This system not only allows the operator to control the installation status, but also to help manage its production.
Stacking: At Fagor Arrasate we have in-house capabilities which simulate and calculate cycle times, with the option of simulating different types of robots depending on the customer’s needs: number of pieces, stacking location, etc.
