What is a spring machine?

Spring machine generally refers to the mechanical equipment for producing springs, and there are automatic type and numerical control type.

According to the functional characteristics, it is divided into: spring press, spring tension machine, universal machine, disc spring machine and special spring machine, such as snake spring machine and torsion spring machine. According to the driving mode, it can be divided into semi-automatic, automatic, numerical control and full computer control. High-end spring machines include FMU series and FUL series of WAFIOS and FMK series specially developed for double torsion, while high-end spring machines include TM series of Japanese MEC, SH series and AX series of ITAYA. RS series, EN5 series in Northeast Taiwan, KHM series in Hong Guang, and conventional mid-end markets include MAX, JYF, Yongteng, Yinfeng, Jingyi, Huayida, Hedong and Cinda. China's Yangtze River Delta and Pearl River Delta have a large number of equipment manufacturing industries occupying a certain share in the low-end market.

The development trend of the industry is the cam-less computer spring machine, which has occupied more and more market share because of its advantages of convenient debugging, fast and stable production, and being suitable for producing special-shaped springs. Cam-less spring machines are mostly 10 axis or 12 axis.

2. Control part

It is divided into mechanical and electrical control devices and numerical control controller devices, and the market is gradually eliminated.

CNC controller mechanical spring machine, with CNC computer spring machine as the development trend. Now it is elaborated by GJ products of domestic Guangjin Spring Machinery Company. It consists of a host computer, a computer control system and a servo motor. It is a spring device integrating mechanism, electricity and light. The computer controller can control the movement of more than two axes, and drive the relevant movement units to accurately process and manufacture various springs. It is an ideal equipment for manufacturing springs with high efficiency and high precision.

Development history of spring machine

Springs are commonly used parts in industry, from airplanes and warships to mobile phones and cameras, so the production of springs has a history of hundreds of years. The original spring is just a cylindrical tension-compression spring, which is wound by hand. The technology is relatively immature and the production efficiency is relatively low. It is very difficult to produce large springs on heavy equipment such as trains or tanks-with the increase of industrial products, spring products have also become rich. Various special-shaped springs, such as tower-shaped (commonly known as battery springs) springs and double-twisted yellow springs, need to be wound by conventional manual methods, and a spring needs 3-8 processes. Even more processes, poor product stability. With the gradual increase of spring consumption, a number of enterprises producing spring equipment have appeared in Germany, Japan and other industrially developed countries, and the related technologies of spring machines have gradually matured. At this time, Germany's equipment manufacturers represented by Wafios gradually became stronger.

In the Asia-Pacific region, there are also several enterprises producing spring machines in Japan and Taiwan Province Province of China. Japan is represented by Bangu and MEC, and Taiwan Province Province is represented by Northeast China (Ding Qiao) and freehand brushwork. MEC's tension and compression spring machine was once known as the printing machine in the spring industry, and Ding Qiao's Northeast Spring Machinery was the pioneer of universal spring machine. With many years of experience in the spring industry, Tu, the founder of the company, independently developed a new type of universal spring machine, broke the technical monopoly in Europe and America, and obtained invention patents in the United States and Japan. Free travel is famous for its large-scale spring pressure throughout the Asia-Pacific region.

In Chinese mainland, the production of springs has been made by hand for a long time. With the accumulation of technology, several spring machine manufacturers have emerged, represented by Luoyang Machine, but the technical stability and accuracy of the equipment have a certain gap with German and Japanese enterprises, especially the control part. In the mid-1990s, the spring machines in the northeast of Taiwan Province Province began to be sold in China, which gradually prospered the spring industry in China. It has also driven a number of spring machine peripheral equipment manufacturers. -With the maturity of spring machine technology, several large-scale spring machine equipment manufacturers such as MAX, Jinyuanfa, Yongteng and Lean have emerged in China. ...

Present situation of spring machine

Spring machine has become a popular name, because the spring is not only the original spiral, but also various shapes-known as line forming machine in the industry. The richness of springs and the improvement of precision also put forward higher requirements for spring machines. At this time, Germany's Wafios, Japan's ITAYA, MEC and other enterprises have developed various types of CNC machine tools by virtue of years of technical accumulation. Wafios equipment has always stood at the top of the spring machine industry-mature technology, stable equipment, humanized control software and rich and diverse auxiliary tools. With the development of Japan's precision industry, Japan's spring machine equipment has developed a variety of precision spring machines, which can produce springs with a diameter of 0.03mm, such as spring brackets commonly used in our cardiac surgery and springs on precision instruments such as advanced ballpoint pens, which can be produced stably and quickly.

In Taiwan Province Province, China, driven by the Northeast Spring Machine, a number of enterprises producing spring machines have emerged, such as NUCOIL, HERDON, Cinda and so on. Compared with the technology of German equipment and the precision of Japanese equipment, Northeast China, the leader of Taiwan Province Province in China, has taken a different approach: with its own patent advantages and mastery of spring forming technology, it has brought its traditional model nucings to the extreme, and with the forming technology of wafios, it has also reduced the cost of the machine to1/3 ~12 of the same type of equipment in Japan, and of course its precision is the best in the industry. There are a large number of imitators in Taiwan Province Province.

Coincidentally, in China's Yangtze River Delta and Pearl River Delta regions, with the hot sale of spring machines in Northeast China and the technical improvement of Luoyang machines, the domestic spring machine industry is booming. From the end of 1990s to the beginning of this century, the spring machine was a money printing machine ~ ~ ~ Haha, at that time, as the boss of spring production said, the spring machine became a hot commodity, compared with German equipment, it was often millions. With the development of the spring machine industry, like the communication industry, a large number of spring machine manufacturers have appeared in the Pearl River Delta and Yangtze River Delta in China. They imitate plagiarism very quickly, even worse than mobile phones. Their equipment is cheaper than the northeast manufacturers, Xinda, Newco and MAX, even less than half the price. The equipment stability is poor, and the after-sales service can't keep up ... but there are also several companies that focus on technology and customers.

The future of spring machine

The technical accumulation of spring machine has gradually matured, and various equipment manufacturers have set up their own professional R&D departments, and even cooperated with some professional universities and research institutes in the field of wire forming to develop the latest equipment. For example, the combination of the latest technology and the latest control technology of WAFIOS, the boss of German spring machine, has reached an unattainable height.

Unique operation control system and exclusive patent structure can be called Mercedes S600 or BMW 7 Series in spring machine. In Japan, companies represented by MEC and ITAYA have raised the accuracy of equipment to a new standard, and developed many special auxiliary devices on their own equipment, which are flexible and convenient to use.

Several enterprises in Taiwan Province Province, the birthplace of China Spring Machine, have developed all kinds of their own equipment, except famous brand old enterprises in Northeast China and free travel. Northeast Spring Machinery set up branches and offices in Chinese mainland around 2000 to facilitate after-sales and close to customers, and directly occupied the Pearl River Delta and Yangtze River Delta two spring production bases in the name of Ding Qiao and Changjin. On the original basis, we also developed a variety of models according to customer demand feedback, and developed some special industrial equipment for specific customers, which filled the gap in the domestic industry and is still improving according to customer demand. If Northeast China is the forerunner of universal machine, then NUCOIL and HERDON are the latecomers. A multifunctional 2 1 axis spring machine developed by NUCOIL won unanimous praise from the world industry at the equipment exhibition in Germany. In a few years, Hedong also developed almost a full range of equipment and exported it to Eastern Europe and the Asia-Pacific region. In Chinese mainland, Max, JYF, Yongteng and Seiko have also developed their own unique equipment, which are leading in the same industry.

It is rumored that in order to compete with the Northeast for the mainland and Asia-Pacific markets, some Japanese and Taiwan Province manufacturers will also set up branches in the mainland, and even engineering R&D departments. If the news is reliable, it will be a good thing for the spring machine industry, which will certainly promote the technical upgrading of the spring machine industry in China and provide more high-quality and cheap equipment for the majority of spring machine manufacturers.

Maintenance of spring machine

Friends who are familiar with machines know that all machines will have certain wear problems after being used for a period of time, and so will our spring machines. After the machine is used for a period of time, the efficiency will be obviously reduced, which will affect the production efficiency. The daily maintenance of spring machine is very important.

The mechanical engineer said that the maintenance of the machine is mainly reflected in the following aspects. First, the cleaning work of the machine, in the process of use, the inside of the machine will gradually become unclean, and for a long time, it will affect some internal circuits, making the internal circuits have poor contact and so on. The second thing we should pay attention to is the maintenance of our machine parts. For example, some parts should be replaced in time, some old parts are worn on the machine, and lubrication of some parts is also very important. In the process of using the machine, if the indexes of some machines are found to be abnormal, the reasons should be found in time to minimize the possible harm. [ 1]

Automatic wire feeding frame of spring machine

Automatic wire feeder is also an indispensable part of spring machine, which is used in conjunction with various types of spring machines. The speed can be adjusted at will; Automatically shut down and give an alarm when a fault occurs; Machine downtime can be set.
