Cold roll forming equipment forming roller to move the body and forming, it is divided into two categories according to the structure: the overall shape of the roller and the combination forming roller. The disadvantage of the integral forming roller is to manufacture complex, and can not replace the easy wear part of the pass, so it is not widely used. The advantages of combination and forming is various and has the advantages of simple processing, can be replaced individually pass in the easy wear parts, gaskets are available to correct pass in the roll gap, roll specifications can be unified, thereby reducing forming machine of molding and reserves. Therefore, this kind of molding and get wide application. But the combination of roll forming and disadvantages, produced in the shape of the axial force is transferred to the roller of the fastening nut, the groove width change, affect the product size precision, now Caigang equipment, C type steel equipment are also using this combination of forming rollers. Roll forming equipment, the surface shall be free from bubbles, cracks, scarring, folding, inclusion, and edge delamination, allowing not greater than 10% of nominal thickness slightly concave, convex, indentation, hairline, bruises, and pressed into the iron oxide. The surface defects of the cold roll forming equipment can be cleaned up by the method of repairing and grinding, but the depth of the cleaning shall not exceed 10% of the nominal thickness. For cold formed steel with high surface quality, the technical conditions of the surface quality should be agreed. Cold formed welded hollow steel welded joints shall not be opened, welded, burned, and serious dislocation. The burr at the weld shall be removed, and the inner burr of the weld shall not be cleaned.
Caigang equipment use, must pay attention to the daily maintenance, prolong the service life is very important. It is almost the cold season, to remind you to use the time to pay attention to the following points, to effectively extend the service life of the press. The welding points of the pressure tile machine 1, the pressure tile machine assembly in the welding stress effect, if the welding piece the restraint degree is small, then the welding part will produce the corresponding size change or the short or the bending or the warping. 2, if the welding parts of a large, such as plate thickness, shape complex or due to the application of the fixture and in a strong constraint, at this time can not be free of deformation, but in the welding stress will produce local strain, and produce a greater residual stress. 3, the peak value of the residual stress in the weld zone can reach the yield strength of the material. The service life of the pressure tile machine Caigang equipment use, must pay attention to the daily maintenance, prolong the service life is very important. It is almost the cold season, to remind you to use the time to pay attention to the following points, to effectively extend the service life of the press. 1, North users such as because of the cold weather, the Caigang pressure tile machine does not produce, please, the mold must be clean, and the mold surface coated with oil, to prevent rusting. If it is used, the paint is produced. 2, in the case of zero temperature, the pressure tile machine before work to take power over 10 minutes before use, so as to avoid a greater noise. 3, Caigang pressure tile machine hydraulic system is the pumping station, in the winter when used to replace the hydraulic oil in winter. In Caigang pressure tile machine equipment, the different moving parts are coated with oil, in the chain and sprocket best coated with butter and then paper wrapped.
In the building materials industry, color steel panel and steel section is applied more and more, has become indispensable in building materials, industry prospects are very broad and the current color steel tile according to the needs of people in the continuous improvement, with light weight, maintenance free, rich color, fireproof and waterproof, good anti-seismic performance, convenient construction, industrialization level is high. 1.Enterprise's industrial plant, many are the use of cold formed steel structure, the weight of the building reduction, the foundation and the part of basic costs, than the reinforced concrete structure of the plant decreased by 45%, this type of industrial plant is more and more manufacturers warmly. 2.The works of the new stadium, railway station, TV tower, parts of their works use the structure of many kinds of cold formed steel, as the main structure of the force construction. 3.Warehouse, automatic management of three-dimensional warehouse, trading market, exhibition hall, active housing, etc. 4.Industrial and civil buildings, they need a large number of doors and windows. From the early fasting steel doors and windows, and gradually developed into today's color plate steel doors and windows, stainless steel doors and windows, plastic steel door and window is made of cold-formed steel products. Fasting steel doors and windows, color plate steel windows and doors and stainless steel doors and windows is directly made of all kinds of cold-formed steel products and components, and in the plastic steel windows and doors, the cold-formed steel is used as inner lining material, in order to enhance the doors and windows of the strength and stiffness. 5.Special doors and windows, such as: shutter doors, fire doors, anti-theft door, and so on, these different categories, but also the use of cold formed steel. 6.In many modern buildings, the glass curtain wall frame also used the production of cold formed steel.
In the real estate industry, color steel tile played a excellent decorative role. Has a strong visual effect. 1.Light dead weight: plant is made of a variety of steel and single color panel, with good bearing capacity, light weight. 2.Low cost: contrast color steel sandwich panel plant, it can save cost 30~80 RMB per square meters. 3.Good seismic capacity: Steel has excellent strength and endurance, the earthquake resistance of 6 degrees. 4.Large span: to meet the needs of all types of real estate.
Engineering machinery The crane lifting arm, the supporting arm, the tower crane frame is also use the cold formed steel technology. Agricultural Machinery Cold-formed steel is widely used in combine harvester, mower, tractor, fertilizing machine, mower, seeder, tractors and agricultural trailers and other various components of agricultural machinery. Such as car frame, machine frame, chassis, chassis, armrest, drive shaft, exhaust pipes etc. In the industry of machinery, agricultural trailers and combine harvester is an important object of popularization and application of cold-formed steel.
