80,000 fasteners to Ringfeder

Shrink discs in stainless steel

▲

Bumax, a Swedish manufacturer of premi- um stainless steel fasteners, has received orders for more than 80,000 screws from German drive and damping technology company Ringfeder Power Transmission in the past year. The fasteners have been in- stalled in more than 7,000 new Ringfeder shaft-hub connections around the world. Ringfeder Power Transmission, a long- standing Bumax customer, has used high-strength corrosion-resistant Bumax stainless steel screws since 2012, as they are able to transmit high torques with the company’s rustproof locking devices. “Bumax was the only company that could provide the high-strength fasteners with the corrosion resistance we required for our applications,” said Rainer Peter, Ringfeder senior product manager for shaft-hub connections.

Ringfeder primarily uses Bumax 109 and Bumax DX (Duplex) 129 screws to provide the necessary strength and corrosion resistance for its demanding applications. The German company operates in niche markets fordriveanddampingtechnology, offering shaft-hub connections, damping solutions and coupling systems for high functionality and durability requirements in a wide variety of industries. Bumax fasteners are now used for all stainless steel Ringfeder products, which are manufactured at the company’s production plants in Germany and the Czech Republic. “The unique advantage of Bumax 109 is its high strength, which means that we achieve the same transmission values with our rustproof shrink discs as our standard

shrink discs with screws of quality 10.9,” concluded Mr Peter. In 2016, Ringfeder also began using Bumax DX 129 screws for some of its products. DX 129 is used in applications where very high strength, ductility and corrosion resistance are required. It offers around 20 per cent higher strength than Bumax 109 and a high level of corrosion protection. Ringfeder rustproof locking devices are used as standard in gearboxes and pumps and other machines. The products are used by pharmaceutical companies, the food andbeverage industry, ingeothermal and hydropower power plants, and in ship drives and packaging machines.

Growing demand for threaded industrial fasteners

A study by Fact.MR on the global industrial fasteners market projects an expansion of around 4 per cent CAGR through to 2031. Speedy recovery and rising demand from various end-use industries, such as building, construction and automotive, will boost sales. According to the study, the growing focus on R&D activities and high-performance quality material is driving the manufacturers’ demand. Significant application in industrial and residential projects in the construction industry, backed by high usage of industrial fasteners such as cable ties, rivets and screws, will bolster the demand for industrial fasteners. automotive, construction industry and industrial manufacturers investing heavily to incorporate advanced technology as a requirement for threaded, non-threaded and aerospace grade is accelerating, is boosting the demand through 2031,” said a Fact.MR analyst. By material, plastic is expected to acquire maximum share, attributed to its popular projects from Springs from Lesjöfors have played a critical role in a progressive student project. A group of technical students in Sweden is competing in global events to develop Hyperloop technology. The Hyperloop concept is being designed to bring super-fast, fossil- free transportation of both people and goods. Scientists, students, designers, programmers, venture capitalists and other businesses are working on cross- border development projects to create the system. It is proposed that the vessels will have top speeds of up to 1,200km/h.

advantages such as being lightweight, flexible and cost-effective. China is expected to be a hotspot for potential industrial fastener manu- facturers in the upcoming years, while India will emerge as a lucrative market for industrial fasteners. In Italy and France, markets will be fuelled by fast recovery of the automotive industry and increasing application of industrial fasteners. According to the study, with the market being highly competitive, key manufacturers are developing and intro- ducing innovative products to expand their geographical reach to cater to the demand. For example, in January 2021, Penn Engineering and Manufacturing Corporation announced the launch of its new website, Profil, for mechanically attached fastener manufacturers. Also in 2021, LISI Aerospace and the University of Sheffield Advanced Manufacturing Research Centre collabo- rated to acquire $1.34mn in funding from the Aerospace Technology Institute, to unlock productivity gains and new The concept is based on a pod, placed in a tunnel or tube, that moves with levitation driven by magnetism. The levitation eliminates friction from the surface and, since the tube is a closed environment, there is no impact from the outside. The air pressure inside the tube is reduced almost to a vacuum, and the reduced air resistance means that the speed can be significantly increased with reduced energy consumption. Springs, with which Lesjöfors sponsored the team, will be used for the lateral control of the pod. Since a Hyperloop pod travels mainly without friction, it is important that the pod does not come into excessive contact with the monorail (I-beam). The springs ensure that the pod always keeps the right course and does not rub against the rails. In addition to the fact that well-defined springs ensure that the pod maintains its speed, they are also important for safety reasons: should the pod crash into the monorail at high speed, there is a risk for serious damage.

markets in the fastener industry through advanced technologies. Key questions covered in the report include: how will demand for industrial fasteners evolve in the future?; which type of industrial fastener accounts for the highest demand?; which is the most lucrative market for industrial fasteners?; what are the factors that will drive the demand for industrial fastener sales?; and what are the winning strategies key players will adopt to generate future prospects?

“Rising Fact.MR’s report presents a detailed seg- mentation of the global industrial fasten- ers market. The study gives insights on the industrial fasteners market on the basis of material (plastic and metal), product (threaded, non-threaded and aerospace grade), end-user (automotive, build- ing and construction, home appliances, aerospace and others), and region (North America, Latin America, Europe, East Asia, South East Asia and Oceania, and MEA).

“We are happy tobe part of such an exciting and important futuristic project,” said Mattias Hartvigsson, product specialist at Lesjöfors. “Sponsoring students for us is both about making important contacts for the future and spreading knowledge about our unique spring expertise.” There is still a long way to go before the Hyperloop vision canbe realised. However, development is progressing quickly and experts believe that the technology can begin to roll out around 2030. Some countries have even higher ambitions and, among others, Saudi Arabia and the United Arab Emirates are aiming to have a Hyperloop operating by 2024. The Lesjöfors group provides a wide range of springs and pressings to customers in industries around the world, with expertise in high-technology, custom-made solutions and a flexible manufacturing capacity.

▲ Exerting pressure on the clamping disc releases the U-Clip

Small and powerful self-locking clips with vibration resistance

Uhing U-Clips are round clamping elements for plain shafts that, with a smooth movement – compress with two fingers, position and release – are pushed against the component to be secured. When released, the clip locks automatically. Featuring high holding forces, the clamping discs of the U-Clips exert a tight grip. Releasing is as easy as fastening. Variants for shaft diameters between 8 and 16mm are released directly at the clamping disc, while versions for shaft diameters between 20 and 35mm are released by lateral pressure on the release buttons.

The Elasto Ring, available for all U-Clip sizes, is a useful accessory. If, for example, the counterforce increases because the spool expands after the U-Clip is fastened, the U-Clip may be harder to release. In this context, the Elasto-Ring offers a simple solution. TheUhingU-Clip reaches topperformance at operating temperatures of up to +50°C. Both available variants are used for positioning on stationary or rotating shafts. U-Clip is equally suited to locking components on shafts or clamping spools on shafts etc.

It is also suitable for quick adjustment of material guides commonly used in packaging machines. The U-Clip can be used on hardened and non-hardened steel shafts. During operation, it is rotationally symmetrical, and does not generate any vibrations of its own, so the component runs smoothly. Compared to devices with balls and tapers, the Uhing U-Clip is highly self-locking. Its vibration resistance and corrosion protection make it durable in appli- cations in a wide range of environmental conditions. Joachim Uhing GmbH & Co KG www.uhing.com

Manufacturing Technology

▲ Sacma’s warm forming technology

Warm forming product lines Hot forging (HF) was the first, and for many years only, process applied to form shaped metal pieces. In the second half of the last century, pushed by the needs of mass production, cold forming (CF) became widespread, initially to produce bolts and screws, and then also for special parts, both solid and hollow. The warm forming (WF) process is positioned between cold and hot processes. less for hot forging and in the middle for warm forming. By WF it is possible to produce more difficult parts than CF, and the range of suitable materials is wider. The key point for WF machinery is to handle the temperature without affecting reliability and precision. For high temperatures, the technology becomes more complex and exclusive. When the products do not require important pre- heating, the machine can be simpler.

A common question relates to the heating temperature to be used. The goal is to define the right temperature for each material, enlarging the plastic field and the limits of deformation just enough to allow the required deformation. For low carbon steels, the WF process is not so relevant, because they are typical materials for cold forming. High carbon and alloy steels require temperatures in the range of 600-700°C. Austenitic stainless steels are heated to 200-300°C to form solid parts and up to 500°C to produce hollow parts by backward extrusion. Typical materials used in the aerospace industry, such as titanium alloys and nickel super alloys, need temperatures from 500 to 850°C.

Focusing on a target of “the right equipment for each demand”, Sacma is now presenting its WF headers product line. The range covers wire diameters from 4 to 25mm and temperatures from room to 900°C. The five and six WF die headers are size 2 (wire up to 10.5mm), size 3 (15mm), size 4 (20mm) and size 5 (25mm). For sizes 4 and 5, just one WF version covers all of the field up to 900°C. For sizes 2 and 3, different models are defined by the maximum reachable temperature: WF300, WF500 andWF900.

The main difference among the processes is, of course, the temperature of the material to be formed. In CF, all the materials start the deformation from room temperature. In HF, the steel blanks are heated in the range from 950 to 1,250°C. In WF, the operating temperature is lower, not exceeding 900°C for steels. The total energy spent to perform the WF process is less than HF and quite similar to CF, because the heating energy is compensated for by the lower amount of deformation energy. The tools are generally more durable for cold forming,
