What kind of machine is needed for bellows?

Bellows forming process:

Hydroformed bellows Hydroforming is the most commonly used forming method for bellows. Using the liquid pressure in the tube blank, the tube billet is swollen in the confinement ring until it yields along the hoop direction, and then the tube blank is compressed to the desired length. This method is mostly used for small diameter bellows.

Roll forming bellows The roll forming process is mainly used for processing large bellows, which is based on the rolling forming of the forming wheel located in the pipe blank, which can be rolled into a single wave, and some devices can also form several corrugations at a time.

Mechanical expansion bellows adopts the fetus that expands inside the tube blank, expands and presses into corrugations one by one, and after the initial forming, it is customized with internal and external fine pressure.

Welded formed bellows For bellows with excessive wave height or special corrugated shape, stamping and welding process is mostly used. When the wave height exceeds the limit, the elongation of the material is no longer allowed to be formed in a monolithic form, or when the monolithic forming is extremely difficult due to the complexity of the waveform, welding forming is also used. Because this kind of bellows cannot withstand internal pressure, it is not suitable for flexible sections of expansion joints.

Deposition of formed bellows This process uses the electrodeposition method to deposit the bellows material onto the mandrel and then melt the mandrel mold. The bellows material is a very soft, pure nickel metal material that is non-porous, so it can withstand high vacuum and can be welded. This type of bellows is not suitable for the flexible section of the expansion joint, because the cost is too high and it is limited to nickel.

Different machines are used for different forming processes.

Stretching machine. One of my customers is the production of bellows. They bought a special stretching machine for bellows in our company. If you need to know the situation, you can call 0757-81280582

The production of stainless steel bellows requires a hydraulic press.

1. What is the bellows used for?

It has a wide range of functions and can be used as a measuring element to convert the generated pressure into displacement or force. It can also be used as an isolating material, and the socks are separated from two different materials to achieve the role of protection. It can also be used as a compensation element to compensate for the temperature mismatch caused by the element, or for the connection between two components.

Second, what are the advantages of prestressed bellows?

1. This kind of bellows is a continuous extrusion model, which has good sealing performance and will not have water seepage or slurry leakage. Of course, whether there will be a problem depends on the skill and proficiency of the installer.

2. The main material used in the prestressed bellows is HDPE, which has acid and alkali resistance, corrosion resistance is very strong, and can reduce the aging rate, prevent rust, increase the service life, and the probability of damage in the later use is relatively small.

3. In the process of use, the friction coefficient between the bellows and the steel strand is not very large, as long as it is left and right, so that the loss caused by prestressed friction can be avoided when tensioning, and the normal use in the later stage is ensured.

4. The flexibility of the bellows is also good, and the ring stiffness is also very high.

5. The bellows used does not have conductive properties, so as to prevent the occurrence of stray current on its own handrails. And because the bending degree of the bellows is relatively large, it can effectively improve the work efficiency. And it makes the connection construction of the bellows easier.

I conclude: what is the bellows used for, and what are the advantages of the prestressed bellows, I will introduce it here, do you understand it? The use of bellows is relatively extensive, and the effect is relatively good, but it is necessary to pay attention to the daily maintenance work, so as not to affect the normal use.

Bellows is a tubular elastic sensitive element connected by foldable wrinkle sheets in the direction of folding and telescoping. The bellows have a thin wall and can be measured in the range of tens of Pa to tens of megapascals. Metal bellows are mainly used to compensate for the thermal deformation of pipelines, shock absorption, and absorption of pipeline settlement deformation.

It is used for force balance elements, and it is required that the effective area of the bellows does not change or changes very little within the working range. The bellows are used as an isolation element and are often combined with a displacement sensor to form a pressure sensor with an output of electricity. It can also be used as a compensating element to compensate for instrument temperature errors with volume variability.

1. Introduction of the manufacturer of bellows.

Bellows is a kind of pipeline used to transport various media, which is widely used in actual production, life and laboratory due to its certain flexibility and elasticity. At present, bellows manufacturers have spread all over the country, among which bellows manufacturers in Jiangsu, Zhejiang and other regions are more concentrated, the production scale is larger, and the supply volume is relatively sufficient.

2. Recommended by bellows manufacturers in Jiangsu.

There are many manufacturers of corrugated pipes in Jiangsu, such as Suzhou, Nantong, Zhangjiagang and other regions. Among them, Suzhou Tianyi Metal Products **** is a professional manufacturer of metal bellows and related products, operating for many years, the products are very popular in the market. Nantong Weaving Machinery Manufacturing Co., Ltd. is also a professional bellows manufacturer, its product quality is stable, and the after-sales service is very good.

3. Introduction of corrugated pipe manufacturers in Zhejiang.

There are a large number of corrugated pipe manufacturers in Zhejiang, among which Wenzhou Mingxiang Electromechanical is an enterprise specializing in the production of metal corrugated orange pipes and rubber bellows and other products, and its products are widely used in construction, petroleum, chemical, food and other industries. Jiaxing Hongyun Machinery Equipment is also a manufacturer of bellows, the company's products are known for their stable quality and reasonable cavity, and are the leaders of the corrugated pipe market in the region.

4. How to choose a bellows manufacturer.

When choosing a bellows manufacturer, you first need to clearly choose the material according to your own needs, and then choose according to the manufacturer's scale, qualification and product quality, etc., in addition, you also need to pay attention to the manufacturer's after-sales service quality and production cycle and other factors. Comparing many bellows manufacturers, you can make a comprehensive comparison in terms of quality, service and other dimensions, and choose the most suitable manufacturer for your cooperation.

5. The future development trend of bellows manufacturers.

With the development of social economy and industrial transformation and upgrading, the bellows industry is gradually developing and growing. In the future, bellows manufacturers need to transform and upgrade from the traditional production and operation model, adopt high-tech means, optimize product structure, and improve product quality. At the same time, the realization of green environmental protection and low-carbon production has also become an important direction for the development of bellows enterprises.

6. Conclusion. Through the above introduction of bellows manufacturers, we can find that bellows manufacturers in different regions are different in terms of production scale, product quality, after-sales service, etc., and the choice of bellows manufacturers needs to be selected according to actual needs. In the future, the bellows industry has broad development prospects, and bellows manufacturers need to achieve leapfrog development through technological innovation and quality improvement.
