Analysis of the manufacturing process of wave springs

Manufacturing Equipment

As an important component in industrial systems, springs have a large amount of use and a wide variety, so the springs are made by hand and are gradually automated.

Ninety years ago in China, the spring industry had very few mechanical equipment for the production of springs. " target=_blank> mechanical equipment. With the increasing market of springs, gradually professional spring equipment companies also entered China, such as Taiwan. Northeast spring machinery (EN Qiaoding), Guanghong (KHM) and other gradually occupied the mainstream spring production market. Northeastern EN502 universal machine

Spring manufacturing equipment

It adopts a proprietary mechanical mechanism to produce various springs and special-shaped elastic components conveniently and quickly.

Guanghong's equipment is a high-speed equipment for producing compression springs and tension springs. There are also many professional spring equipment manufacturers in foreign countries such as Wafios, MEC (now ORII & MEC). At present, the production of large-scale spring CNC hot-rolling machines in China is still blank. Although the spring industry is a small industry in the entire manufacturing industry, its role cannot be underestimated. The expansion of spring production and sales scale, the increase of varieties, and the improvement of quality level are also the needs of mechanical equipment "target=_blank> mechanical equipment replacement and the improvement of supporting host performance. Therefore, for the development of the whole country's industry, spring products have played a role. Important role.

Since the reform and opening up, with the globalization of the economy and the establishment of China's manufacturing power status, the demand for springs has surged. In addition, the investment in spring production is not high, the technical threshold is low, and investment recovery is fast. Since the 1980s, the number of spring production enterprises has increased rapidly. By the end of 2010, there were 724 enterprises above designated size in the spring manufacturing industry, with more than 100,000 employees. In 2010, the sales revenue exceeded 30 billion yuan, and the total profit exceeded 1.6 billion yuan.

Spring is a very competitive product. In the market, domestic enterprises with low-end products have cost advantages and competitive prices. High-end products and foreign-funded technologies have advantages, and cutting-edge products, such as those used to treat cardiovascular diseases. The stents are almost exclusively monopolized by foreign medical giants, and domestic companies have done nothing. Automobile springs are the hottest areas for domestic and foreign companies to compete for. The domestic and foreign companies have different strengths and are difficult to distinguish between each other.

The spring industry has gradually entered the competition of the industrial chain from the past price wars and service competition, and the industrial chain is to be completed by standardized means. Although the industry's standard system is relatively complete, due to the early development, the market demand has a considerable distance, especially compared with developed countries such as Japan, Europe, and the United States, the current national standards and industry standards are still low, leading to domestic The spring products are not competitive in the international market. Therefore, the introduction of new industry standards that are in line with international standards is the primary problem that the industry needs to solve.

During the "Twelfth Five-Year Plan" period, thanks to the relevant national policy stimulus and the revitalization plan of related industries, China's automobile, railway, instrumentation and other industries will maintain rapid and stable development. In addition, some emerging industries such as conventional weapons, nuclear power and aircraft manufacturing are lacking in the participation of springs. As China's national strength grows stronger and the national defense technology investment becomes more abundant, this is also an important aspect of the spring industry business opportunities. In the context of a good external environment and steady growth of downstream demand, China's spring industry will maintain rapid and stable development. It is expected that by the end of the “Twelfth Five-Year Plan”, that is, in 2015, China's spring industry will reach sales of 60 billion yuan.

Cold forming

1) One-time automation of cold forming process. The cold forming machine has been carried out to 12 claws. The Steel Wire in the range of (0.3 to 14) mm can be formed at one time in the 8-claw forming machine. The development direction of the forming process equipment: 1 Progressive forming speed, the main development trend is to improve the forming speed of the equipment, that is, the consumption efficiency; 2 to improve the durability of the equipment by improving the fineness of the equipment parts and strengthening the heat treatment effect; 3 increasing the length sensor and The laser range finder stops the automatic closed-loop control manufacturing process for the CNC forming machine.

2) The scope of the cold forming process. Large-diameter spring coil spring machine, the maximum size can reach 20mm, =2000MPa, and the winding ratio is 5. Cold forming processes for tapered or equal-diameter Minic-Block springs and eccentric springs are still limited.

Hot forming

1) The speed of the hot forming process. China's (9~25)mm specification is only CNC2 shaft hot coil spring machine, the maximum speed is 17 pieces per minute. Compared with the prosperous country, the gap is large.

2) Large spring hot forming process control ability. Since only the CNC2 shaft hot coil spring machine, the shape control has less three directions, and the precision is poor; and there is no automatic bar material rotation control and adjustment mechanism, so the degree and ability of the hot coil spring forming process is low. Therefore, the degree of precision of the spring and the degree of oxidative decarburization of the surface are also low.
