　　Culvert channel steel bending machine Jingheng customized channel steel bending machine production base

　　Bending machines are now widely available in the market, capable of completing bending tasks for various types of steel such as channel steel, track steel, and round steel pipes. Different types of steel arches and arches with different angles require different grinding tools. The recognition of the bending machine in the market is very high now. Greatly improving the construction speed of profiles and saving labor for workers.

　　The I-beam bending machine enables continuous cold bending operations while ensuring the strength of the steel. It can meet the diverse requirements of different construction designs for the size of steel arches, improve the processing quality of steel arches, accelerate the processing speed of steel cold bending, and greatly reduce labor intensity and labor costs. The I-beam cold bending machine adopts a hydraulic system, which has the characteristics of smooth transmission and high pressure, and can be positioned during the I-beam processing. Widely used in the cold bending treatment of I-beams, channel steels, and section steels in highway tunnels, railway tunnels, subway tunnels, water conservancy and hydropower diversion culverts, natural gas pipelines, communication pipelines, underground passages, and other engineering projects in China. Due to the long-term bending of arch steel, the stability requirements for rolling of I-beam cold bending machine are relatively high. Although the manufacturer has been working hard to break through and overcome such technical difficulties, it is still not so perfect. In work, it is still encountered that weak stability leads to swaying back and forth when bending arch shaped materials. In fact, such problems are quite common in the production process, and there is no need to panic when encountering culvert channel steel bending machine. Jingheng customized channel steel bending machine production base.

　　Reason analysis and solution for uneven radius in the same piece of finished arch frame:

　　In the same processing of the same I-beam, without any movement of the hydraulic cylinder and without any joints, it was found that some arches were bent and straightened one by one, which sometimes made it difficult to install. The reasons for this are as follows: 1. The bending machine was produced in the early years, and hydraulic cylinders were usually used as jacks to support the middle driven wheel. However, due to the lack of a check device in the hydraulic system or oil leakage such as piston leakage, the cylinder would retreat after being subjected to force, some of which were very slight and could not be observed by the naked eye. However, the radius of the arch formed by cold bending would be much different, and it would become significantly straightened, that is, the radius would increase. If the oil leakage was severe and the roof would fall, it would be obvious at a glance. The solution is to... Modify the machinery by removing the hydraulic system and replacing it with a mechanical jack, We usually use Shanghai Baoshan brand 100 ton screw jacks to process our own cold bending machines, which can avoid the above problems. It is simple and practical, and basically does not require repair and maintenance. 2. Another issue is that the drive wheel bearings have worn out, causing the shaft center to be eccentric. This situation is usually caused by a large bearing under the shaft, because the cold bending machine usually does not install a sealing device on the lower bearing, and the iron powder will run into the bearing and eat the lubricating oil. Moreover, the cold bending machine does not have an oil passage or grease fitting for refueling. Based on this, the cold bending machine can only be cleaned frequently, and if you don't pay attention to the bearing, there will be iron powder, which will quickly cause the bearing to break down; 3. I-beams are irregular and have different work tolerances. Simply put, they have varying levels of fat and weight, usually exhibiting non-standard behavior; 4. Processing I-beam arch joints is also a key technology. The radius of the joint cannot be straightened, and the joint must be straightened. When bending towards the center of the circle, the radius of the arch will increase. Otherwise, the small culvert channel steel bending machine and the customized channel steel bending machine production base will be established.
