https://www.jinggongmachine.com/process-characteristics-of-coldformed-steel-processed-by-cold-roll-forming-machine.html

Cold-formed steel is different from hot-rolled steel in that it is formed by bending in a cold state and without reducing the cross-sectional area.

 1. Classification of cold-formed steel processing technology of cold roll forming machine

 The roll forming process of cold-formed steel can be divided into four types, namely single-piece forming process, coil forming process, continuous forming process, and combined processing process. On the cold roll forming machine unit in industrial production, any process is divided into three stages: the blank preparation stage before forming, the forming processing stage, and the finished product finishing stage.

 2. Different forming process characteristics of cold roll forming machine

 The blanks entering the cold roll forming machine are sheets cut to a fixed length, and the formed cold-formed steels can be collected and bundled out of the factory without shearing.

 Compared with the continuous process, this process has a higher forming speed, which can reach 180-220m/min, but the required forming tools are more complicated, and the geometric shape and dimensional accuracy of the product are poor. The equipment of the single-piece roll-type cold forming unit is simple and the investment is less.

 The coil forming process is the same as the continuous forming process, the difference is that the tail of the previous roll of the strip is cut and butt welded with the head of the next roll of the strip during continuous forming so that the blank strip continuously enters the cold roll forming machine for forming. The bending machine is used for forming; when the coil is formed, the head and tail of the coil are not welded, and a single-coil is fed and formed. The product quality of these two processes is better than that of the single-piece molding process. However, the equipment is more complex, generally equipped with cutting shears and butt welding machines, and sometimes loopers to ensure continuous operation. These two processes require fewer bending holes, and the forming speed is related to the cutting equipment behind the cold bending forming unit and the cutting speed of the equipment, generally 30-90M/min, and some cold roll forming machine units reach 100-250m/min.

https://www.jinggongmachine.com/why-cant-the-cold-roll-forming-machine-be-overused-how-to-avoid-failure.html

We believe that everyone now has a certain understanding of the cold roll-forming machine. As a commonly used product, the cold roll forming machine can be said to be used very frequently, but do you know that the cold roll forming machine cannot be used excessively? How should we avoid the failure of the cold roll forming machine? Let's find out together with us.

 1. Why can't the cold roll forming machine be used excessively?

Ⅰ. About cold-formed steel processed by cold roll forming machine

 The steel production method is roughly divided into two categories: hot working and cold working. Cold-formed steel is produced by cold working. Cold working includes stamping and drawing.

 The cold roll forming machine processing cold-formed steel refers to forming on a cold roll forming machine so that the strip is continuously passed through the 3-20 slurry cold rolling mills arranged in series, and the forming process is performed in turn, and the finishing is rolled to the required shape.

 Compared with hot-rolled steel, cold-formed steel is often a variety of varieties with smooth surfaces, thin walls, and unique shapes that cannot be produced by hot-rolling. This kind of steel has the valuable advantages of lightweight and economical use, so it is a variety that has developed rapidly in recent years.

 Ⅱ. Characteristics of cold-formed steel processed by cold roll forming machine

 In addition to cold-formed steel for general components, auxiliary steel for decks, and steel for guard plates, there are many types of steel. The characteristics of several of these steels are described below.

 When cold-formed steel for ship structure is used as a building material, it has the following advantages:

 1. The properties of steel can be reasonably utilized when designing the section shape. Compared with the previously used hot-rolled profiles, the properties are superior.

 2. It has the advantages of being lightweight, high section performance, and less steel used. Material costs and basic engineering costs can be saved.

https://www.jinggongmachine.com/the-production-standards-for-stainless-steel-composite-panels-processed-by-cold-roll-forming-machine.html

Ⅰ. The thickness dividing line of stainless steel processed by a cold roll forming machine is different

 The 1987 standard stipulates that the total thickness is 20mm, the 1997 standard stipulates that the total thickness is 25mm, and the processing method of thicker steel plates is refined.

 Ⅱ. The production standard of stainless steel composite panels processed by cold roll forming machine

 Stainless steel composite cold-rolled sheet steel processed by cold roll forming machine has broad application prospects in light industry, food, construction, decoration, welded pipes, and other industries. Before this, there were no special national standards and international standards in the world.

 In 1997, based on the enterprise standard of this variety of Taigang, the first generation standard of China's stainless steel clad cold-rolled sheet "GB/T17102-1997 Stainless steel clad cold-rolled sheet and strip" was formulated.

 1. The shear strength specified in the 1987 edition of the national standard for the production of stainless steel composite panels is not less than 147MPa;

 2. The national standard for the production of stainless steel composite panels in 1997 version 1, 2 is not less than 210MPa, and the third is not less than 200MPa;

 3. The 1997 version of the national standard for the production of stainless steel composite panels is higher than the 1987 version, and the Japanese standard stipulates that all levels are not less than 200MPa;

 4. The determination of the lower limit of strength can not only be based on the base layer but also can be calculated by a specific formula;

https://www.jinggongmachine.com/the-springback-of-bending-parts-of-cold-roll-forming-machine.html

When cold roll forming machines process, the problem of spring-back after bending often occurs. We will analyze the measures for the spring-back of the bending parts of the cold roll forming machine in detail.

 Ⅰ. What is the spring-back of the bending parts of the cold roll forming machine?

 Plastic bending, like all plastic deformation, is accompanied by elastic deformation. When the bending deformation is over and the bending part of the cold roll forming machine is not affected by an external force, the elastic recovery makes the angle of the bending part and the radius of the fillet of the bending part inconsistent with the shape and size of the mold. This phenomenon is called the spring-back of the flexure.

 Because the spring-back directly affects the dimensional tolerance and shape tolerance of the bending parts of the cold roll forming machine. When designing the mold, the spring-back value of the material is taken into account in advance, and the size and shape of the working part of the mold are corrected.

 Due to many factors affecting the rebound, it is impossible to give accurate data whether it is theoretical calculation or empirical data. Therefore, after the data is generally given, it needs to be corrected in the trial mold, and then the correct die size is determined.

 Ⅱ. Measures to reduce the spring-back of the bending parts of the cold roll forming machine

 Bending parts have shape and size errors due to spring-back, and it is difficult to obtain qualified bending parts. Therefore, measures to reduce the springback are taken as follows.

 1. The design of bending parts

 Improve the design of the bending part to reduce the spring-back. It can be pressed and strengthened in the bending area to improve the rigidity of the bending part, suppress the occurrence of springback, or select materials with stable mechanical properties and small fluctuations in sheet thickness. Also try to avoid the selection of a excessive large bending radius.

 2. The craftsmanship

Since the seventies, with the development of cold-formed steel production, roll cold-forming machine processing equipment has a series of improvements. Some set up presses for pre-forming before the roll cold-forming machine, some also include punching slot, top heat, punching, tempering, welding and other processes. With the reform of the process, the cold roll forming machine unit equipment composition also changed.

 The Soviet Union and Japan divide the cold roll forming machine into two types according to the process: continuous forming machine, roll cold forming machine and single-piece forming machine.

 1. Continuous cold roll forming machine unit

 The characteristics of this type of unit are that the coiled strip is used as the blank, and the coil head and tail are sheared, butt welded, straightened, and the strip loop storage device is used in the feeding stage of the continuous cold forming unit;

 The blank strip is continuously cold-formed by the forming machine, and the finished product is cut to a fixed length by a flying shear or a flying saw when the material is discharged. The product quality of this unit is good, the production efficiency is high, and the metal yield is high.

 2. Cold roll forming unit

 The characteristics of this type of unit are that the coiled strip is used as the blank, and the single coil is formed. In the feeding section of the coiled cold bending forming unit, there is only an uncoiler and a straightening machine.

 Its equipment is simpler than the continuous cold forming unit, and there is no butt welding machine and looper. The equipment of the discharge section is the same as that of the continuous cold forming unit. The product quality, production efficiency, metal yield, equipment quantity and investment of this type of unit are between those of a continuous cold-formed forming unit and a single-piece cold-formed forming unit.

 3. One-piece cold roll forming machine unit
