A System More Compact Than A Conventional Transfer Press

A System More Compact Than A Conventional Transfer Press

With the Compact High Speed Servo Tandem Line, AIDA Engineering has developed a flexible, more-compact system that meets the demands of tomorrow’s jobs.

The right automated press setup meets not only the requirements for today’s stamping jobs, but allows for flexibility to meet the demands of tomorrow’s jobs.

Transfer operations have been widely used in automated systems, however, since all forming processes are performed in one press, the transfer press must necessarily be large.  Such Large size brings a number of concerns:

  1. A transfer operation means major investment because of required accessories, such as floor scrap conveyors.
  2. Because the press is large, a large pit is required, increasing the initial cost.
  3. Large press size dictates high rigging and transportation costs.
  4. Larger dies mean higher costs and more storage space.
  5. Large press size makes changing the press layout difficult.

For stampers, remaining competitive requires them to make the right technology choices, to not only meet current job demands but also to have the infrastructure in place to support customers’ future requirements. Stampers can support ongoing growth and productivity by considering these primary elements when choosing new pressroom equipment:

  1. Press equipment should be flexible and have the capability to produce a variety of parts. This type of versatility means pit-less on the shop floor and less overall capital equipment costs.
  2. Press automation must be considered, to boost overall output.

On a more fundamental level, press equipment must be reliable and well maintained.

A Flexible Option

In recent years, a flexible alternative automated transfer press system called ‘Compact High Speed Servo Tandem Line’ has begun attracting attention because it can compensate the conventional transfer press systems. The system was achieved by using a general-purpose servo press at each stage and linking these presses using high-speed transfer robots—enabling a newly designed platform for dedicated robot lines.

So, how does a compact high-speed servo tandem line achieve the ability to match the size of a large press? By arranging the small servo presses in tandem for each process, it is possible to optimize different processes at a time. In transfer processing, there are various forming processes such as drawing, bending, trimming, punching, and coining, to name a few; but in the compact servo tandem line, each process can be set independently and optimum slide motion can be achieved. 

Equipped with a predictive function that avoids interference between the timing of the press slide and robot transfer motions, it enables synchronization of the entire line without slowing the line speed, thereby achieving productivity that is even equivalent to that of a large transfer press.

Compared to the conventional transfer press, which performs multi-step process operations with one slide, it is possible to bring out the features of the servo press to an even greater extent. When used in a compact servo tandem line, automation can deliver improved productivity as parts move from press to press.

With the configuration, there was an issue that the timing of process and material transportation is different in each process. Therefore, AIDA installed a transfer device independently in each press, and set up a mechanism to transfer according to each slide operation non-processing timing. This determines the optimum line speed based on the slide motion set for each press and the transportable time calculated from SPM, for the speed of the entire line.

In other words, by adjusting the non-processing area time of each press so that it can be applied to one cycle of the entire system, it is possible to synchronise the entire line without lowering the line speed compared to the past. The system also has the flexibility to add multiple presses later to change the line configuration.

Servo System Versatility

To further improve flexibility and uptime, servo technology stampers can produce a range of parts from materials such as aluminium and magnesium alloys, and high-strength steels and titanium alloys, while achieving higher speeds and working energy, and improved control and precision.

Pre-programmed motion curves and the ability to design programs unique to the job at hand, along with the ability to change from producing one part to the next quickly, also add to the system’s versatility. Operating in continuous mode can deliver even higher productivity rates.

Advantages

1. Enhanced frame rigidity

Using a press frame that is symmetrical front-to-back delivers uniform front-to-back elongation and improves dynamic accuracy.

– AIDA is working towards even better durability by taking measures to reduce stress concentrations.

2. Isolating electrical components to extend service life

Electrical components are located in separate cabinets to isolate them from stamping vibration. This extends the service life of electrical components.

3. High-speed transfer robots NCAH-III (S)

AIDA has effectively increased the productivity of a conventional compact tandem line, thanks to high-speed transfer robots and high-precision synchronised controls.

As the entire line can be synchronised without sacrificing speed while still avoiding interference between the timing of the press slide and robot transfer motions, it achieves an equivalent, or even better, productivity than a dedicated transfer press.

In addition to that, a separate press slide for each stage of the forming process not only reduces the effects of off-center loading, but also enables the choice of optimal forming motion for each stage of the process. This contributes significantly to uniform product accuracy.

4. Reduction of factory equipment cost

Utilising compact presses in tandem will also change the conventional factory equipment design. Unlike larger transfer presses, the physical size of a compact servo tandem line system is relatively small. The height of the building, which was decided according to the machine height of the large press, can be kept low. The compact servo tandem line can be placed without preparing a pit for installing the press, making it possible to considerably reduce the equipment cost in the factory.

Since large buildings and deep pits are not required, factory capital investments, such as the capacities of cranes and the power of air conditioning, and equipment power, are significantly reduced too. Such system does not require any large accessory equipment, making press-layout changes a breeze.

This is a major advantage for companies that are expanding, as it significantly reduced the amount of capital investment.

5. Space-saving design

When combined with a NCAH-III (S) transfer robot system, the installation footprint of a line composed of six 2,000 kN presses is 40 percent smaller than a conventional transfer press.

6. Synchronised operation servo motion

Thanks to dedicated press slide for each process stage, forming is possible with optimal motion for each stage.

Stampers that install flexible equipment and incorporate a system-wide approach to make automation part of their operations have an opportunity to remain competitive with lower-cost labour markets.

Global Dies, Jigs And Fixtures Market To Reach $88.8B By 2023

Global Dies, Jigs And Fixtures Market To Reach $88.8B By 2023

The global jigs, fixtures, and dies manufacturing market reached a value of nearly $56.8 billion in 2018, having grown at a compound annual growth rate (CAGR) of 8.6% from 2014, and is expected to grow at a CAGR of 9.3% to nearly $88.8 billion by 2023, according to a new report by The Business Research Company.

Previously, the main drivers of the market were the rise of manufacturing activity in emerging markets and increased spending on construction projects, while the main restraints were fluctuating raw material prices. Going forward, the main market drivers will be the growth in the automobile industry, technological advances and growth in consumer markets.

One of the key drivers of the dies, jigs and other tools market is the increased spending on construction projects. The market benefitted from the rise in metal consumption by the construction industry globally. Buildings with metal structures have become a standard choice for the construction of commercial and industrial facilities. For instance, around 40 million tons of steel were used in the construction industry in the United States in 2018. According to the Metal Building Manufacturers Association (MBMA), 34% of its members’ sales are generated from commercial buildings. This rise in metal consumption increased the demand for tools used for welding positioners, jigs and cutting dies.

Major trends influencing the dies, jigs and fixtures market include automation, and additive manufacturing and 3D printing. Automation tools and robotic solutions are being used by tool manufacturers to reduce downtime and increase productivity. Automatic tools include the use of computerized control systems for operating manufacturing equipment. Major automatic tools include smart camera systems, intelligent control systems, shop floor monitoring systems, 3D vision technology and robotic material handling systems. Robots allow faster assembling of complex components as compared to traditional manufacturing techniques. Robots also automate milling, trimming, drilling, cutting and forming processes, thereby reducing the production time. Automation further enables machine manufacturing companies to significantly increase production volumes with automation technologies, thereby decreasing production costs and increasing profit margins.

Meanwhile, tool manufacturers are also increasingly deploying additive manufacturing technologies to offer customized designs to customers. Additive manufacturing refers to the application of 3D printing to create functional components including prototypes, tooling and end-use production parts. Additive manufacturing aids in cost-effective production of small batches of intricate parts and complex part designs. It provides a high degree of design freedom, optimization and integration of functional features, and product customization.

Opportunities and Threats

The dies, jigs and other tools market size will gain the most in China. Meanwhile, the top opportunities in the global market will arise in the stamping and other tools segment, which will gain $22.7 billion of global annual sales by 2022. In fact, the stamping and other tools segment was also the largest sector in the global dies, jigs and fixtures market, with more than 67% of the market share, worth around $38 billion, in 2018. This higher share was due to extensive use of equipment to give shape to metals by electronics, automotive, metal manufacturing and plastic manufacturing companies, and the higher prices of these products compared with the prices of dies, and jigs and fixtures. Going forward, the stamping and other tools segment will continue to grow the fastest, growing at a CAGR of 9.7% between 2018 and 2023. The other segments of the market—dies, and jigs and fixtures—will grow at 9.2% and 8.3%, respectively, during the period.

The main threat, meanwhile, will be trade protectionism. Trade barriers are expected to have a negative impact on the market as many countries are placing trade restrictions, especially on imports, to boost local production. For instance, Brexit is likely to lead to more trade restrictions between the UK and other countries in Europe. The US is also implementing several trade restrictions, especially with China, to boost its local production. For instance, the US imposed 25% tariff on steel and 10% tariff on aluminium, in 2018. Steel and aluminium are extensively used in manufacturing of these tools. These trade restrictions are likely to limit the growth of demand going forward due to higher prices.

Innovation Drives Metal Stamping Machine Systems Forward

Innovation Drives Metal stamping machine Systems Forward

Metal stamping machine tools are seeing updates with new servo motor technology and intelligent machines. By Michael E Neumann

The global automotive industry Metal stamping is in better shape than it was five years ago, especially in the US where profits and sales have recovered following the recent economic crisis, and in China where growth remains strong, according to McKinsey & Company’s recent study on what is driving the global automotive industry to 2020 and beyond.

The management consultancy found four key challenges that OEMs need to address to get a piece of future profitability:

  • Complexity and cost pressure: There will be more platform sharing and more modular systems. At the same time, regulatory pressures will tighten, and prices in established markets are likely to be flat.
  • Diverging markets: OEMs need to adapt to changing regional and segment patterns of supply and demand with respect to their production and supply base footprints, supply chains, and product portfolios; and the emerging Chinese aftersales market offers new growth opportunities.
  • Digital demands: Consumers want more connectivity, are focused on active safety and ease of use, and are increasingly using digital sources in making their purchase decisions.
  • Shifting industry landscape: Suppliers will add more value in alternative powertrain technologies and in innovative solutions for active safety.

A Piece Of The Pie Metal stamping

To capture future growth and find profit from these challenges—and to mitigate their risks—OEMs cannot simply turn to their traditional toolbox. They need to review and adjust their strategic priorities, deploy the appropriate investments and resources, and develop new skills to execute these strategic objectives Metal stamping machine.

Press equipment manufacturers like Seyi are following suit. The company delivered a 400-ton straight side servo press and an 800-ton straight-side eccentric gear servo press to automotive OEM Daimler Group in 2016, and the company will soon complete an 800-ton straight-side servo press for Tesla Motors in USA. The company has focussed on three main themes, which were also on display at the recent Taipei International Machine Tool Show 2017.

Servo Technology

Along with creating less noise, servo motors also offer energy savings over hydraulics. However, the largest advantage is the ability to control slide position and velocity. Practical applications of this precise control include what the company calls “vibration motion curve”, which is especially suitable for deep drawing and creating diverse metal parts. A “pendulum curve motion” can also reach speeds of 170 strokes per minute.

Press Line Management

The company has been developing a production process called “Intelligent Press Line Management Systems”, which can manage all necessary production items, including the operator, machine, tooling, maintenance, process and more. The integration of hardware and software, big data, analysis on the cloud are also included to meet clients’ requirements.

Automation Solutions

The company already has automated solutions for tandem lines leaded by 1,200 to 2,400 ton presses. Transfer systems, material input and conveyor equipment can also be provided. The company also recently partnered with industrial robotics supplier ABB to offer metal stamping automation systems, including one press with one robot, one press with multiple robots, and multiple presses with multiple robots.

Working In Tandem

The car industry faces challenging times, according to a report by Euler Hermes. The rise of the shared economy, new partnerships with disruptive technology companies, high volatility in some emerging countries, the race to launch autonomous vehicles, and diesel scandals rocking big players are happening all at the same time.

Yet, a global presence remains a must for car manufacturers to benefit from global growth. Car manufacturers and their suppliers will need to continue adapting their offerings to stay competitive.

“The automotive industry has always been one of the fastest growth engines for Seyi. We will continue to work with customers in this industry, and focus on tier one and two OEM customers,” said Seyi chairman and chief executive officer Claire Kuo.

Quick Look: Global Automotive Metal stamping machine Report 2016

A global automotive report released by Euler Hermes highlighted that the three key markets for sales are China, US, and Europe.

In China, sales grew by 15 percent (24 million units) in 2016, but a slowdown to around five percent is expected in 2017. A 1.5 percent decrease in Japan is caused by the continuously adverse effects of the value-added tax increase in April 2014.

US sales grew by 0.2 percent (17.9 million units) in 2016 but a contraction of one percent is expected in 2017. In Europe, sales expanded by seven percent (15 million units) in 2016, while “zero percent” growth is forecasted in 2017 due to the Brexit effect and the end of Spain’s incentive regime.

Brazil and Russia continue to suffer from the economic crisis. Markets have contracted by 21 percent and 11 percent respectively. A subtle recovery is anticipated in 2017.
