As bicycles become more and more popular, their construction and accessories are becoming better known. Some of the Bike parts require regular maintenance or replacement, such as the chain and brake panels. Proper chain tension is essential for efficient power transfer from the pedals to the rear wheel. If the chain is too loose, it can lead to slippage and loss of power. If it is too tight, it will cause unnecessary friction and wear on the chain and bike freewheel. The chain tensioner is a key component in maintaining the correct tension in your bike's chain. It ensures that the chain runs smoothly and does not slip or jump off the sprocket. And the bottom bracket is the central component that holds the crankset (the pedals and gears) in place and allows it to rotate. A well-functioning bottom bracket is vital for a smooth and efficient ride. If the bottom bracket is worn or damaged, even rainy riding causes seepage, it can cause friction, creaking noises, and even prevent the crankset from rotating properly. So it's important to check the bike status in time to ensure safe riding. We have almost all the parts for the whole bike, the bike stem in alloy, the seat post in multi-size and so on. bicycle parts,bike chain,chain tensioner,bottom bracket,BMX MID BB Suzhou Jingqiyao Intelligent Technology Co., Ltd. , https://www.jingqiyaoparts.com
As a kind of non-contact machining, laser processing has become an indispensable process in various production stages of industrial manufacturing in recent years due to its high quality, high output rate, high flexibility and high applicability. It has gained a high degree of recognition in the past ten years. In the period of general weakness in the machining industry, it can still rely on an average annual growth rate of more than 20% to lead the mechanical equipment industry forward in a dark horse.
The reason why this achievement can be achieved is inseparable from the blessing of robotics.
As everyone knows, in the rising of various high-tech technologies, the application advantages of robots in the field of industrial manufacturing and their remarkable, not only can replace the manual 24 hours of work, but also reduce errors and errors, in some extreme environments. operation. Therefore, the combination of robot technology and laser processing technology has integrated a new robot laser processing technology, which has changed the drawbacks of traditional laser processing and brought new impetus to the development of the industry.
Robot laser processing is getting hotter
From the time point of view, the emergence and development of laser technology and robots are relatively synchronous, but the two have been in parallel for a long time, and it was not until the end of the 1990s that the first intersection occurred. In 1999, the German robot company first integrated the first robotic arm with a laser processing system, which opened the robot to help laser processing.
Compared with traditional laser processing, the application of the robot makes this light knife break the limitation of the dimension, and the operation is more flexible and more convenient. Although the traditional laser is widely used, low power can be used for precision machining such as marking, engraving, drilling and micro-cutting. High power is also suitable for cutting, welding and repairing large metal materials, but it is limited to planar two-dimensional processing. The application space has serious limitations, and the integration of robot technology just makes up for this.
Therefore, in recent years, the application of robots in laser welding, cutting and other processing fields has become increasingly hot. Robot laser cutting is free to cut because it is not controlled by the cutting direction. It is also called 3D laser cutting. It has become a new fashion in the development of the industry. Because 3D laser welding is not as simple as cutting, it needs to consider more factors. Large-scale applications have not been ushered in, but their advantages and application potentials have gradually emerged and become known.
At present, China's robotic laser processing technology and equipment have passed the initial stage from scratch, and are entering the accelerated period of development from small to large. With the gradual application of robot laser processing in industrial fields such as metal processing, cabinet production, elevator manufacturing, agricultural machinery manufacturing, shipbuilding, etc., its industry development has formed a certain industrial scale.
Especially in the field of automobile manufacturing, it is to push the development of robot laser processing in China to the era of large-scale application. At present, 50%-70% of auto parts need to be processed by laser, and the development of China's auto industry continues to expand, which brings a huge demand market for robot laser processing. It is understood that nearly three years. The power battery soldering application of new energy vehicles alone has brought billions of equipment demands to the laser industry.
With such market demand as a support, a large number of robotic laser processing companies have emerged in China, including leading companies in the laser field such as Dazu, Huagong and Chutian, as well as powerful robot companies like Xinsong and even Dongguan Lisheng Automation, Foshan Hobel, Hangzhou Kelda and other enterprises engaged in the development of automated control equipment.
Three major problems constrain large-scale development
Nowadays, with the strong demand in the application market and more and more companies, coupled with the strong development of the robot and laser market itself, the development of robot laser processing has gradually improved. However, at present, its large-scale application is still worrying. Even in some large automobile manufacturing enterprises, the procurement of robotic laser processing equipment is only about ten or so. The main reason is that the three problems restrict its scale. development of.
The first is the technological gap and shortcomings in the robotics and laser industries themselves. China started late and its foundation is weak. There is a clear gap between the two technologies and core components. It has a lack of driving force for high-end development. At the same time, enterprises represented by the four major families occupy major domestic markets and let domestically produce them. The brand lacks the opportunity to verify the application of technology, and the corresponding industrialization of laser robots has lost its support.
Second, there is insufficient internal communication between the robot and the laser industry. Although there are many companies involved in the laser industry, from the field of lasers, from the field of robotics, from the field of automation, but the cross-border cooperation between them is extremely scarce, technical exchanges and industrial integration are extremely lacking, all of which are closed-door vehicles. This makes the research and development of various links in China lack practical application needs.
Finally, there is a lack of order and standard specifications in the development of the robotics and laser industries. Since there are no corresponding industry norms and standards in the two major industries, the industry competition is in a disorderly state. The poor self-discipline in the industry leads to the formation of good cooperative relations between SMEs, R&D institutions and large-scale enterprises. Their respective factors have not passed. The exchange of exchanges between enterprises has been lifted, which has led to more vicious competition.
Foreign institutions have predicted that the global robot laser processing market will expand to 40 billion U.S. dollars in 2020, and a blue ocean is already in front of countries and enterprises. In the future, how can Chinese enterprises sail in this ocean and go forward in the past? Only by solving the above three problems can we know!
China's robot laser processing industry ushered in initial development
The emergence of robot technology has brought new development opportunities for the application of laser processing technology. Today, China's robot laser processing industry has ushered in initial development, the market has considerable scale, and the future industry needs to achieve a more breakthrough scale. Development needs to solve some problems.
