Process Characteristics of Cold-formed Steel Processed by Cold Roll Forming Machine

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.

 The combined machining process is used to process cold-formed steel with specific requirements, such as high-strength cold-formed steel, closed-end welded steel, heat-treated cold-formed steel, periodically corrugated plate, punched cold-formed steel, etc. The equipment of the combined processing cold forming unit is complex, including a straight seam welder, butt welder, press, roll punching machine, roll grooving machine, coating machine, shearing machine, and heat treatment equipment.

The Springback of Bending Parts of Cold Roll Forming Machine

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

 Corrected bending is used instead of free bending, and the material hardened by the cold forming machine must be annealed before bending.

The Classification and Characteristics of Roll Cold Forming Machine Units

https://www.jinggongmachine.com/the-classification-and-characteristics-of-roll-cold-forming-machine-units.html

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

 Its characteristic is that the coiled strip is cut to a fixed length by a fixed length before the roll-type cold bending forming machine, or the original inclined plate of the fixed length is transported by the unit. The blanks are fed into the forming machine one by one for single-piece forming. The equipment of this unit is simpler than the above two, and the investment is lower, but the quality of the product is poor.

Requirements for Processing Profiles of the Cold Roll Forming Machine

https://www.jinggongmachine.com/requirements-for-processing-profiles-of-the-cold-roll-forming-machine.html

1. What are the blanks of the processed profiles of cold roll forming machine?

 The steel blanks processed by the cold roll forming machine include plain carbon steel plates, high-quality carbon structural steel plates, low-alloy steel plates, stainless steel plates, coated (plated) laminates, etc.

 Coated (plated) steel plate includes painted steel plate, PVC coated steel plate, plastic coated steel plate, organosol coated steel plate, propylene-based plastic coated steel plate, vinyl chloride coated steel plate, vinyl plastic coated steel plate, galvanized steel plate, tinned steel plate, chrome-plated steel plate, nickeled steel plate, etc.

 2. The blank material of the processed profiles of the cold roll forming machine

 The material of the blank depends on the use, shape and specifications of the cold forming sectional uranium. With the development of the processing technology of cold roll forming machine in recent years, high-strength steel plates can be heated locally or as a whole for roll forming and the tensile strength limit of the plates can be greater than 60 kgf/mm2. The roll-type cold roll forming machine, which is generally not heated in the past, requires that the tensile strength limit of the blank is below 60 kgf/mm2.

 For the cold forming sectional steel that needs to be welded after it is formed in the cold roll forming machine, no oil is allowed on the surface of the blank during welding, otherwise the welding quality will be affected. For cold forming sectional steel with complex cross-sections, the yield point of the blank is required to be low, and the crystalline structure of the blank should not have free cementite, otherwise cracks and surface pits will occur in the bending part.
