(Roll Forming Uncoilers) - Failure Analysis

(Roll Forming Uncoilers) - Failure Analysis

Uncoiler is one of the main production of (light steel keel machine )settings, and because of its specificity to the metal frame machined product quality plays a decisive use. Currently the role of the domestic use of (light steel keel machine) uncoiling device is uncoiler sizing rack steel roll up tight, which requires a lot of tension. This tension is usually obtained from the axial force changes uncoiler, thus requiring a large axial force. However, due to the limited spatial structure restrictions generally axial force generated by (light steel keel Uncoilers) need help converting round nut locking tension.

Extensive use of (light steel keel machine )

 Extensive use of (light steel keel machine )

All week, (roll forming machine), you can easily and fast processing of a variety of different forms and different uses of sheet metal products. (Light steel keel machine) processing out of the metal frame used for roofing buildings. With the rapid development of China. (Roll forming machine)products are used in various fields. In fact, the keel keel machined in 2010 Shanghai World Expo has played a lot of use. Expo venues in laying the roof is to use gypsum board, light steel keel, mineral wool acoustic board and other decoration materials. For (light steel keel machine), light steel keel production equipment including unwinding machines, molding machines, cutting machines. Because of the special structure which uncoiler, failure rate, maintenance for a long time, plus the use of its production is indispensable to play, so the quality of the product within the Strut dragon great impact.

Roll forming machine - cylindrical gear molding method

Roll forming machine - cylindrical gear molding method

Spur gear is one of the most basic parts transfer motion and power, in the engineering field, particularly in the automotive and manufacturing industry has a very wide range of applications. Roll Forming Machine spur gear not only complex shapes, and dimensional accuracy, surface quality and mechanical properties are demanding. At present, the domestic production of most of the spur gear using traditional machining methods, materials utilization is low, low productivity, high production costs, and because the metal fibers are cut to reduce the gear strength and service life. Spur gear is a little plastic forming precision machining without the new technology, the ultimate aim is precision molded plastic forming a complete tooth and tooth surface without subsequent machining or finishing allowance leaving only a little. Roll Forming Machine Compared with the traditional cutting process, spur gear precision plastic forming with significant advantages materials, energy saving, low cost, high efficiency, tooth uniform continuous distribution of fibrous tissue along after forming, increasing its mechanical properties.

Development of cold-formed steel roll forming process technology

Development of cold-formed steel roll forming process technology  

  By conventional molding methods: conventional roll forming machine production and a variety of square and rectangular hollow steel profiled most of the first round after a variance, rectangular or shaped tubes. Roll forming machine production of cold-formed steel due to the development of new technology, and now the use of anti-bending roller type design (ie, W-type roller design), starting shape, and bend the strip edge, while in the middle of the strip to give and a direction opposite to the curved edge of the bending deformation, low consumption because of wave and side portions extending bulge caused. This method is new technology to improve the roll forming machine to produce large diameter thin-walled circular products have a significant effect, and because some of forming rolls can be shared, will help to improve product quality and reduce the cost of roll film.

Roll forming machine installation and commissioning

 Roll forming machine installation and commissioning
Roll Forming Machine embedded parts should be accurate and solid, basic to meet the design requirements, and to allow the installation to achieve strength. Factory QTJ4-25 block making machine according to the relevant provisions have been made ​​in the factory are factory test, but because of long-distance transport and long-time placement and other reasons, the installation should be carried out the following checks:
1 Check the machine during transport if there is damage or deformation;
Two main parts of the machine checks whether there is loosening fasteners;
3 Check the gearbox, the exciter vibration table sump lubrication points are required each refueling, fuel is appropriate;
4 Check the main transmission and brake motor braking effect is sensitive and reliable.
Also wipe the machine fully working, roll forming machine even before the test machine and moving parts on the site according to the provisions relative sliding lubrication. If the machine apart due to transportation needs can be divided into forming device, plus base unit, charging device, roller sets and electrical control box and other parts, roll forming machine installation, assembly according to assembly relationships in place.
