Application Of High Power Laser Cutting In Sheet Metal Processing


Laser technology is one of the four major inventions in the twentieth century, along with atomic energy, semiconductors and computers. It is known as “the fastest knife”, “the most accurate ruler” and “the brightest light”. However, the technology did not break through the original technical bottleneck until the 21st century. At the same time, the combination of laser technology and advanced equipment promoted the development of advanced equipment manufacturing industry. The word sheet metal is not unfamiliar to everyone. Almost all manufacturing industries will have sheet metal processing. If you count the cutting process of sheet metal (the thickness of the metal sheet is below 6mm), it is nothing more than laser cutting, plasma cutting, and flame cutting. , shearing machine, stamping, etc. Compared with the traditional shearing process, laser cutting has the advantages of higher cutting accuracy, higher material utilization and productivity. As a precise processing method, laser cutting can process almost all materials, including thin metals. 2D or 3D cutting of plates. In the field of sheet metal cutting, efficient cutting can be performed from ultra-thin sheets of microns to thick sheets of tens of millimeters. Laser cutting has incomparable advantages over traditional cutting. It can be said that laser cutting has set off an important process revolution in the sheet metal processing industry.

Working principle: The material to be cut is irradiated with a high power density laser beam, so that the material is quickly heated to the vaporization temperature, and evaporates to form a hole. Sew, complete the cutting of the material – this is laser cutting (LaserCutting). Laser cutting has high efficiency, high energy density and flexibility. Whether in terms of accuracy, speed or efficiency, it is the best choice for the sheet metal cutting industry. The laser can be focused into a very small spot, which can perform micro and precision processing, such as processing of micro slits and micro holes. In addition, it does not need a tool for processing, which belongs to non-contact processing and has no mechanical deformation. Some traditionally difficult to cut or low-quality plates can be easily solved after encountering laser cutting. Especially in the cutting of some carbon steel plates, laser cutting has an unshakable position.

The average person may ask, what can laser cutting do for the general public? Then it has to be mentioned that it plays a vital role in the application field of industrial manufacturing. Laser cutting equipment is the basic equipment necessary for pillar industries such as aerospace, ships, automobiles, and energy equipment. It represents the current world of laser technology and The development direction of its application can not only solve some technical problems in the construction of major projects, but also play a leading role in the formation and development of the country’s emerging laser processing industry in the future.

Laser technology is constantly bringing us surprises and innovating the manufacturing methods that have been constrained for many years in the industry. In recent years, laser processing equipment has been rapidly popularized. In 2017, the sales volume of complete sets of laser cutting equipment in my country exceeded 25,000. The high-power large-format fiber laser cutting machine has a large cutting width and a fast cutting speed that greatly exceeds people’s imagination in the past. It can cut thicker metal sheets and has stable performance, which is an inevitable trend in the development of laser cutting technology. Nowadays, high-power laser cutting machines are very popular in the sheet metal market. With the in-depth application of laser cutting technology, it will further promote the laser cutting technology in the field of sheet metal processing to move towards high precision and high power, which marks the high level of laser cutting. The era of power is coming!

The development of laser cutting is inseparable from the upgrading of laser technology. During the period from 2003 to 2008, gas lasers were still the mainstream of metal cutting, but due to the high cost of millions, only a few large-scale enterprises had the purchasing power. In 2008, Hua-Russian Laser launched the first self-developed large-format solid-state laser cutting machine. The market price was around 580,000 yuan, which was in line with the mainstream market demand and was well received by the sheet metal market. After that, with the rapid development of business volume, Hua-Russian Laser entered the fast lane of development, focusing on enriching the product line of fiber laser cutting machines, with power from 500W to 10000W, and optional formats from 3015 to 12030, and developed high-speed fiber lasers for automatic loading and unloading of flat panels. Automatic production line supporting solutions such as cutting machine, automatic professional pipe cutting machine, automatic uncoiling and leveling laser cutting production line. As a Sino-foreign joint venture high-tech enterprise integrating product research and development, production and sales after ten years, Hua-Russian Laser has won more than 50 national patents and more than 20 national, provincial and municipal scientific and technological achievement awards, and continues to lead the international and domestic laser industry. The innovative development of products has become a global professional laser intelligent equipment manufacturer. At the beginning of 2019, Hua-Russian Laser relied on the self-developed VWJ series high-power fully enclosed exchange type 15000W high-speed fiber laser cutting machine, which has the characteristics of high power, high speed, high efficiency and high precision. With its flexible processing range, powerful Cutting penetration ability and higher processing efficiency have become the representative of the latest productivity in the field of laser cutting.

VWJ series high-power fully-enclosed switching high-speed fiber laser cutting machines compete with each other, why do they stand out? It is a subject worthy of our long-term contemplation. In today’s environment, Hua-Russian laser cutting technology presents two obvious trends, one is high-power large format, and the other is intelligent automation, keeping up with the pace of the times and responding to the call of Made in China 2025, in the wave of laser cutting , Hua-Russian Laser will further improve R&D, production and after-sales service, deepen Sino-Russian technical cooperation, and benefit customers by virtue of the characteristics of high, large, fast, good and provincial, so as to achieve the purpose of reducing costs and increasing efficiency.

Efficient buck regulator power modules enable space-efficient and simpler designs

Infineon Technologies AG has introduced highly efficient and reliable step-down DC-DC converter modules. Adding to the PoL family, these modules are ideal for system designers looking for compact, fully integrated, and simple-to-design POL products to assist them in speeding time to market. They primarily address space and thermally constrained telecom and datacom applications, servers, and network storage.

TDM3883 and 3885 IPOL are fully integrated single-output buck converters, providing a high-efficiency continuous 3A/4A load capability and line regulation across a wide input supply range (4.5-14V). The integrated Inductor and Capacitors lower external components and enable easier designs with far higher power density. The integration delivers improved performance compared to discrete solutions due to the low parasitic parameters by minimising the PCB wiring trace required. At the same time, thanks to their tiny package size, the modules fit into the restricted PCB space providing up to 80% area saving on the customer solution. In these optimised modules, the company excessively tests the integrated inductor and capacitors in reliability and final test, removing the effort of passive components selection and test.

The modules offer a low supply current (10μA) at shutdown producing longer battery life for portable applications. Also, their tight reference voltage V REF tolerance (0.5V±1%) and low ripple offer accurate power delivery and contribute to system stability and reliability. They employ an Enhanced Stability COT engine with ceramic capacitors without external compensation and a FCCM option to further support this. Also, the modules come with thermally-compensated internal OCP, enhanced light load efficiency with reduced switching frequency and DEM. With ultra-light loads, they can enter a low quiescent current mode making it excellent for standby power supplies. Other features comprise internal soft-start, enable input, pre-bias start-up, thermal shut down, a power-good output, OVP, and UVLO.

Carbon Fiber Materials For Construction


Buildings are constantly damaged during use and affect their safe use. The most economical method is to reinforce and repair them.lThe application in strengthening and repairing concrete structures has attracted attention at home and abroad, and research and development have been started. In the late 1980s, a new technology for strengthening and repairing buildings with carbon fiber composite materials was developed abroad, and it was widely used in the 1990s. After the earthquake in Japan in 1994 and the reconstruction and repair after the earthquake in Taiwan, China in 1999, carbon fiber also played an important role.
 
There are three main aspects to consider when using carbon fiber in buildings. First, a set of design and construction specifications that are different from traditional reinforcement and repair methods must be established. Then, a new basic theoretical database of materials and design methods must be established. Prototype materials for new technologies, such as carbon fiber woven fabrics, unidirectional fabrics, mixed fabrics, primer resins, adhesives, and new construction equipment, are gradually forming an industry. In general, the reinforcement and repair technology currently used in my country is still very backward, and new technologies and prototype materials are rarely used, which will be gradually eliminated. As a new technology, carbon fiber reinforced repair is welcomed by various countries, and it has actually proved to be very effective.
 
The traditional method of repairing bridges is to use steel plates to surround the piers and then spot-weld the seams, and the middle needs to be filled with cement. The steel plate is easy to rust, and it is very troublesome to maintain it regularly every year. If you use carbon fiber material, you only need to stick the carbon fiber with resin, which saves a lot of work and costs, and does not require much maintenance in the later stage.
 
Not only is it used for reinforcement and repair, but carbon fiber rods can also be directly used in building structures, and carbon fiber felts can be mixed with concrete. Use open.

Analyze The Performance Advantages Of Carbon Fiber Robotic Arms


With the continuous development of science and technology, the application of robots has gradually increased. Our common robots are mainly industrial robots to replace human beings to perform heavy and single work and reduce labor intensity. The mechanical arm is the main part of the work. Carbon fiber machinery Arms are gradually being used instead of traditional metal robotic arms. Let’s take a look at the performance advantages of carbon fiber robotic arms.

 

The most significant advantage of carbon fiber material is its light weight, its density is only 1.7g/cm3, which is 60% of the traditional weight reduction material aluminum alloy, less than 1/4 of that of steel, which helps to achieve lightweight structure and more convenient operation. , and can prevent the problem of unstable center of gravity caused by the excessive weight of the arm itself.

The mechanical arm is the main part of the work, and it is also the main load-bearing member. It needs good support performance. The specific strength and specific stiffness of carbon fiber materials are better than most structural materials, and the load-bearing performance is outstanding. When a few fibers are broken, the load will be rapid. Distributed to other unbroken fibers, it will not cause damage in a short time, and has good fatigue resistance.

The operation accuracy is also very important for the robot arm. The performance of traditional metal materials is unstable and prone to corrosion, and the strength of metal materials is not high and easy to deform. Carbon fiber is a non-metallic material with excellent corrosion resistance and anti-aging properties and long service life. Its thermal expansion coefficient is small, and it will not creep with the change of operating temperature, thus ensuring accurate operation.

The electronics industry actively participates in the battle of epidemic prevention and control, Heraeus donated 1,000 sets of UV germicidal lamps

The 1,000 sets of UV germicidal lamps donated by Heraeus’ special light source have arrived at the front line of anti-epidemic in Huanggang, Hubei, where medical supplies are urgently needed.

Heraeus is a global group company headquartered in Hanau, Germany for the production of precious metals and technology supply.

It is reported that on February 11, Heraeus Special Light Source contacted SF Express urgently, and arranged a special vehicle to transport the donated ultraviolet germicidal lamps from Shanghai to Hubei and sent to the Huanggang Epidemic Prevention and Control Headquarters. It has been delivered on February 12, and will be distributed to hospitals in the jurisdiction that are in urgent need of supplies.

Recently, the National Health Commission and the State Administration of Traditional Chinese Medicine announced the “Diagnosis and Treatment Program for Novel Coronavirus Pneumonia (Trial Version 4)”. The new version of the diagnosis and treatment plan writes that the virus is sensitive to ultraviolet light and heat.

Heraeus technical experts introduced that when the cumulative UV dose received by most bacteria and viruses reaches 20mJ, the inactivation rate can be as high as 99% or more. The 253.7nm ultraviolet light can effectively destroy the genetic material (DNA or RNA) of microorganisms, so that bacteria and viruses cannot complete the replication and transcription of genetic material, thereby killing bacterial pathogens and eliminating the source of infection.

1.2kV dual gate driver for SiC mosfets

Called AgileSwitch 2ASC-12A2HP, “the gate driver provides multiple levels of control and a higher level of protection for silicon carbide mosfet-based power systems,” according to the company. “Key performance attributes include the ability to dampen drain-source voltage overshoots and slash switching losses”.

The driver can source and source up to 10A peak, and includes an isolated dc-dc converter with a low capacitance isolation barrier for pulse width modulation signals and fault feedback.

It is not clear if this 10A is from the 2ASC-12A2HP itself or with the associated nodule adapter board (MAB) – diagram left. Clarification has been requested.

Output voltage can be bipolar: positive from +15 to +21V, and negative from 0 to -5V. Power for this  comes via an on-board isolator from 15V.

It is compatible with the latest release of Microchip’s Intelligent Configuration Tool (‘ICT’, free download), which allows users to configure gate driver parameters including the gate switching profiles, system critical monitors and Controller interface settings.

“The result is a gate driver that is tailored to their applications without having to change hardware,” said the company.

As well as the software, there is a family of module adapter boards match footprints with the company’s Augmented Switching Accelerated Development Kits (ASDAK), that include gate drivers, module adapter boards and a programming kit.

12:1 input range dc-dc for railway and industry

TDK-Lambda has created a 200W dc-dc converter series that can accept inputs across 14 to 160Vdc, a 1:12 range.

Called PYH200, packaging is industry-standard board-mount half-brick, measuring 61 x 58 x 12.7mm.

For EN 50155 (railway rolling stock) applications, the converters are potted with silicone for shock and vibration resistance.

Variants are available with 12, 15, 24 or 48V nominal outputs (±1%), adjustable over -20% to +15% to deliver non-standard voltages.

Efficiency is up to 90% in some models and the parts can be conduction cooled with base plate temperatures across -40 to +100°C – heatsinks for convection cooling and forced air cooling are available.

Remote sense, remote on/off and external clock frequency synchronisation are included, as is hold-up extension by connecting an external capacitor, Resistor and diode.

Other external components are essential: a fuse, a 240µF aluminium capacitor for operating stability, a 1µF ceramic multilayer and a 10µF aluminium or tantalum for good transient response (with ESR caveats), and a 100µF 200V capacitor and SMCJ180A suppressor diode if EN61000-4-4 or EN61000-4-5 need to be met. Additional filtering is also recommended under some circumstances – see the data sheet.

Protections include over-current, output over-voltage and over-temperature.

Input to output and input to baseplate isolation is 3,000Vac with an output to baseplate isolation of 500Vac.

Certification is to IEC/UL/CSA/EN 62368-1 safety standards with the CE and UKCA marks for the Low voltage and RoHS Directives.

“PYH200 in combination with a typical test setup has been tested to meet the EN 50155, EN 45545-2, EN 61373 and EN 50121-3-2 railway standards,” according to TDK.
