New strategic partnership between Pivatic and RAS

03/22/2021

The aim of the strategic partnership is to offer to customer the strengths and advantages of the two industrial entities Pivatic Oy and RAS Reinhardt Maschinenbau GmbH and to strengthen both competitive position in the sheet metal machine tool markets. For Pivatic the co-operation with RAS brings wider product offering and higher flexibility for bending solutions specially with small and medium size volumes in sheet metal manufacturing.

RAS Reinhardt Maschinenbau GmbH and Pivatic Oy has been announced a strategic partnership. Both RAS bending centers and Pivatic punching systems have been known and established on the sheet metal machine tool market for decades. In the new cooperation model, the two companies contribute their know-how in punching and bending and offering lines for their customers as a joint solution.

With the unique Pivatic-RAS solution, two sheet metal processing technologies are integrated in a single production line: coil feeding or sheet punching by Pivatic and bending by RAS. Compared to other traditional systems, the material only moves once through the Pivatic punching line and the result is a punched part that is produced faster than any other traditional solutions.

This punching speed in combination with the bending speed and flexibility of the RAS bending centers leads to an automated flexible production solution that is characterized by low cycle times, high productivity, low logistics and handling costs, high design freedom in part construction and low costs per part.The integrated line is very compact and requires only a minimum of floor space. Due to the flexibility of both technologies, this modular line is suitable for large production batches as well as for small and medium quantities.

The punching process can start from sheets or from coils. The Pivatic punching machines can process coils from the width of 60mm up to 1825mm and from the sheets from 200mm up to 1825mm. Pivatic additional cut-to-length (CTL) and cut-to-length (CTW) integrated shears deliver precise and long cuts for the bending process. The RAS bending module can consist of one of the three bending centers with maximum working lengths of 2160mm, 2560mm and 3060mm. After bending, the finished panels can be forwarded in subsequent lines as automatic welding or stacking.

The control system software organizes the data communication to the machines of the production line, send information to an ERP system and creates statistical data. State-of-the-art technology meets industry standard 4.0. The programming of the punching and bending processes is based on 3D and 2D CAD drawings can also be carried out automatically.

The list of benefits of the common solution is long. The direct linking between the main processes reduces the logistical effort and improves the material flow, which has an economic impact, especially in the case of large components with small quantities. As a result of the linking, a finished bent product is always created after one pass and no stock of semi-finished products accumulates between punching and bending. The automated processes reduce human intervention and possible errors or damage during handling.

The largely synchronized processes during punching and bending increase throughput and efficiency, which ultimately also leads to lower part costs. Since up to 120 punching tools are accessible at the same time during punching, there are practically no tool change times. The challenging scrap skeleton handling is also eliminated with this approach.

At the RAS bending center, the punched blanks are automatically turned if necessary and then loaded, aligned, positioned, bent and unloaded. Automatic tool set-up and bending up and down without turning the part are an important matter of course. The automatic bending sequences ensure maximum precision and repeatability, which is also suitable for laser welding. Bending without damage to the surface of the material and without tool wear are outstanding properties, especially in stainless steel applications.

Pivatic, based in Finland, was founded in 1975 and is part of the Ursviken Group. Over 450 sheet metal processing systems are convincing proof of the efficiency in automatic punching.

RAS looks back on more than 80 years of experience in sheet metal processing and completes the systems with its bending centers.

EuroBLECH in Hannover, Germany on the 25 – 28 October

Meet us at EuroBLECH 2022 – Stand E136, Hall 11! We will be showcasing a fully automated servo-electric coil punching, cutting and pressing line on the stand. Highly efficient and indexable Thick Turret punching combined with a separate cutting station and a press tool station of 1200 kN punching force allows jobs like hole group, embossing, corner notching and trimming to be flexibly produced. Energy consumption for the full line is between 12-18 kWh, depending on the use of the big press, which is 60-70% less compared to traditional systems. This supports Pivatic’s low-energy product solutions well toward global sustainable development.

The line is bought by a German manufacturer who will receive the line after the exhibition with two coil cars, a turning drum, and a stacking device that are not present at EuroBLECH. The line is made in custom blue line color.

Why double punch?

Pivatic double punching technology was a product of developing the mechanical structure of the tool cassette technology and cycle time of the punching line.

TAKE A GREEN LEAP

Lower your energy costs and intensify your production with Pivatic line solutions. Thanks to servo-technology you can save up to 60-70% in electricity compared to traditional systems, lowering your maintenance costs and total noise level. By using standard coils less scrap is produced in both your production and your steel suppliers.

An article in the Finnish sheet metal magazine Ohutlevy goes in depth about the start of the Pivatic brand, punching technology, and what are our modern capabilities. Starting page 45, read here: https://digiplus.fi/www/Ohutlevy/2022_No1/index.html#p=45

The Pivatic PivaPunch System – How Does it Work?

The PivaPunch may be best described as a hybrid between a turret punch press and a coil-fed stamping press. he PivaPunch system utilizes standard “Thick Turret, Amada-Style” tooling mounted in precision-machined tooling cassettes. The number of tools required, and their sizes is dictated by an evaluation of the application. Cassettes can hold up to 26 tools (52 tools total because there are two (2) cassettes in a standard PivaPunch system.)  In cases where even more tool capacity is required, readily available multi-tool holders that can hold up to nine (9) individual tools can be installed in specific stations to increase the tool capacity to up to 100 total. Individual tools up to “F” size (6” diameter) can be accommodated, and up to two (2) tool stations can have auto-index capability.

Ponad 100% większa wydajność wykrawania detali z dużymi otworami

Duży amerykański producent urządzeń HVAC planował przyspieszyć swój proces produkcyjny za pomocą nowej technologii wykrawania. Firma miała już wcześniejsze doświadczenie z linią wykrawającą Pivatic, zainstalowaną w 2007 roku, na której wykonywała niektóre detale. Dostawa nowej, innowacyjnej linii Pivatic pozwoliła zastąpić wolnostojące wykrawarki rewolwerowe oraz zwiększyć wydajność produkcji detali z dużymi otworami o ponad 100% – skracając tym samym czas cyklu z 4-5 minut do 2 minut.
