The cold roll forming production line has the criterion of uniform stress in each pass, which can extend the service life of the roll. In production, it should be designed with balanced force, accurate processing, and convenient installation and adjustment. The cold bending machine ensures the strength of the material, improves the quality of the supporting steel arch, greatly improves the work efficiency, and is easy and clear to operate. Comparing the two, both have outstanding performance. Cold roll forming is a material-saving, energy-saving and efficient new process and new technology for sheet metal forming. Using this process can not only produce high-quality section steel products, but also shorten the product development cycle and improve production efficiency, thereby improving the market competitiveness of enterprises. The general cold roll forming machine process includes: Sheet forming, roll forming and continuous forming, joint forming. The single-sheet forming process is to cut the sheet into a specified length in advance, and then send the sheet into the forming machine through the selection roller. The rolled profiles can be directly collected and put into storage, especially suitable for cutting easily deformed products after the plate is formed, mostly used for small batch production. Its advantages are simple equipment, low investment and small footprint Customized cold roll forming machine: The process of roll forming and continuous forming is basically the same, and their difference is that the joints of the continuously formed plates must be welded to make the plates form continuously; while the roll forming is a single roll supply. The equipment investment and floor space required by these two processes are relatively large. Combined forming process is a forming process for processing special steel. Sectional steel has special requirements for forming process and requires messy forming equipment, which is suitable for processing high-strength plates. The equipment requirements are complex and the investment is high. Cold roll forming machine price: In recent years, cold-formed steel products have been widely used as important structural parts in many fields such as construction, automobile manufacturing, shipbuilding, electronics industry and machinery manufacturing. The products of cold roll forming machine range from ordinary guide rails, doors and windows and other structural parts to some special profiles made for special purposes, with a wide range of types.

Method 1: Apply anti-rust paint We can coat the surface of the cold bending machine with anti-rust paint. There are many colors of anti-rust paint. Can be used in red, green or silver, are quite beautiful.After painting, it can not only prevent the cold bending machine from rusting, but also has a decorative effect. Method 2: Strengthen nursing type. Before painting the cold bending machine, the surface should be carefully polished with a steel wire grinding head on the angle bending machine.This is to completely remove the rust, then paint, and then paint the anti-rust paint, which will be firmer. Method 3: Nano antirust paint In today's developed modern society, there is a high-tech paint called nano antirust paint,It can not only prevent rainwater, seawater, acid and alkali, but also prevent ultraviolet light.And it is very suitable for cold bending machine equipment. Method 4: Select a place to place The cold bending machine should be in a dry and ventilated place, not suitable for a humid environment, which is also one of the ways to prevent the cold bending machine from rusting.

1. The circular arc part of the track is the core part of the slide rail. The circular arc position after the first few presses is formed. When the vertical edge is rolled and folded in the subsequent pass, the formed circular arc should be effectively protected by the upper and lower rollers or horizontal wheels. Otherwise, the arc position of the material will definitely change during the stretching process, the R becomes smaller and becomes a triangle, the steel ball does not reach the bottom, and the two-point contact produces noise. Uneven stress, deformation of the slide rail, and shortened life.  2. The principle of average force in each pass, average force on the entire line of rollers, balanced wear, and prolong the service life of the rolls.  3. The problem of rolling stability. In production, the problem of material swaying left and right in the raceway is often encountered. In fact, the single set of rollers is asymmetrical. The force on the left is large, and the material sways to the right; the force on the right is large, and the material Swing to the left.  4. The use of C12MoV material for the roll is to take advantage of its wear resistance, but the specific strength and hardness are contradictory. The red hardness of C12MoV must be used during heat treatment. After quenching, tempering twice or even three times can reach the hardness.

1. Cantilever cold roll forming machine. This equipment structure can limit the width of the forming strip to the length of the cantilever shaft. It is possible to press some products with thin profiles, or products with wide plate width and only one side of the profile. This method is not suitable for products with excessively pressed profiles, because only one side is stressed. 2. Double-ended cold roll forming machine. This structure is two cantilever installations and both sides of the strip, the width can be adjusted freely from inside to outside, and at the same time, products of any width can be formed within the limited width. 3. Through-axis double-end cold bending machine. The axial deflection of the through-shaft cold bending machine is smaller than that of the cantilever machine of the same specification. On this cold roll forming machine, the rolls are fixed on the racks on both sides. 4. Standard cold roll forming machine. This type of equipment is supported by bearings on both sides, and the bearings are fixed on the side plates. 

In terms of control: the hydraulic cold bending machine is controlled by a PLC program controller, and the automatic reader of the full hydraulic system can be controlled manually or numerically. Operation: Unlimited feeding, forward and backward, automatic positioning of the progress size of the oil cylinder without manual measurement, automatic reading of the bending size. In terms of safety: double automatic shutdown system, automatic shutdown when reaching the specified size, infrared braking system, automatic shutdown when there is no material. During use, due to production wear and tear, equipment failures are prone to occur, which will affect the smooth progress of production, and serious accidents such as economic losses and personal injuries will also occur, which will affect safe production. Therefore, it is very necessary to maintain and maintain the cold bending equipment regularly. 

1.First of all, choose a flat table, put the machine stable, you can pull the chassis foot to make the machine panel easy to observe. Insert the plug of the handheld sensor head into the socket on the panel and tighten it, taking care to locate the gap. 2.Secondly, plug one end of the power cord into the socket on the rear board of the chassis, and plug the other end into the power supply socket. Be sure to use single-phase three-wire power supply. Then open the "POWER main switch (POWER SW.)" on the back of the chassis, press the "power switch (SWITCHING)" key on the panel, and wait for the" WARM UP "green indicator to light up, the machine can work. Press and hold the "SETTING BUTTON" key to set the appropriate value, generally between 0.5-2.0 seconds. 3.Put the sensor head on the container cover again, press the start button on the handle, then the red indicator light of "HEATING" indicates that it is HEATING, do not remove the sensor head, and remove the sensor head after the red indicator light of "heating" is off. 4.Finally, after the "WARM UP" green indicator lights up or the buzzer in the machine makes a short "beep" prompt, the next container can be sealed. Check the sealing quality, according to different materials, diameter of the container and production efficiency, appropriate dressing of the "SETTING BUTTON" key, so that the sealing quality is better.
