Development of cold-formed steel roll forming process technology

Development of cold-formed steel roll forming process technology (2) Roll forming machine with plug-in vertical roll forming machine in the production of rectangular hollow steel products, with direct prescription, rectangular tube method gives good angled shape, and the general method of forming into a square circle, rectangle compared to the simple, to save time, the most important new roll forming machine can reduce wasteful consumption caused blank. In the unit of production capacity, a combination of roll film can meet all the specifications to maximize the square, rectangular steel products, than roll costs required by the variance round, rectangular molding process to save more than 60%, showing that the new roll forming machine technology can not only get the best quality of products, but also the economic benefits of a good harvest.

flexible roll forming machine Unit Features

flexible roll forming machine Unit Features (Roll molding machine) in the production of different specifications of steel pipe, without changing the roller, only the level of the rough-shaping roller segment frame of four and six frame roll holder vertical displacement of the roller group of the rack may be adjusted. (Roll forming machine) in the operation simply press the operation button, through the electro-hydraulic control and mechanical transmission device to adjust the roll up, down, sliding, rotation, can be read directly from the adjusted digital display technology to accurately adjust the roll parameter, so that not only reduce the roll change time, simplifying adjustment step, and the number of rollers can save prepare 30% -60%. (Roll forming machine) As the pipe forming process a bad edge tension in small, fixed shape without offset shift, flat seam, roundness. Thus product quality and stability, roll wear, low rolling mill energy consumption, and for the production of some of the thin-walled pipe (such as t / d = 1%) offer possibilities.

Flexible roll forming unit

1 Flexible roll forming unit Referred FCF unit (Flexible Cold Forming) in order to meet a variety of openings and cold-formed steel hollow preform requirements by the VAI developed a new type of unit, in 1992 and put into use. Features (roll forming machine) units are: arch through the rack with rollers roll film alone or synchronized movement, so that the profile section of the wings bent alternately or simultaneously, to change the products of different specifications in each rack, and without the replacement roll, and thus (a roll forming machine) to adjust the manufacturing operation more excellent flexibility. FF units (Flexible Forming) is a flexible machine on behalf of another type.

(Roll forming machine) units advantages

(Roll forming machine) units advantages Simple (roll forming machine) frame structure, easy to adjust, can save 50% of the cost of the roll film, a 40% reduction when changing rolls. To 15% of capacity. Diameter and wall thickness (roll forming machine) product ratio D / T up to 160:1 advanced technology applicability. Produce diameter of 25 to 406.4mm, wall thickness of 1 to 16mm tube product line and the corresponding rectangular tube.

Focus adjustable forming roll forming machine

Focus adjustable forming roll forming machine (Roll forming machine) generally use a common frame and a preformed flange rack, an apparatus dedicated substituted 4-5 CTA conventional two roll holder flat edger roll means and the frame. (Roll forming machine) CTA means to produce the main pipe, the changes in size, just adjust the position of the sheet roll changes can be realized when adjusting the roller, which moves the linear resistance, adjusting the roll angle is constant constant, the linear movement of the roller is formed with a radius proportional to the product. (Roll forming machine) for the production of square and rectangular tube, the integer is a universal rack and roll, when to change product specifications, simply adjust the four staggered flat, vertical roll position, you can achieve the production requirements.

The new (roll forming machine) several structural forms

The new (roll forming machine) several structural forms Molding technology and equipment is increasing the level of structure, endless leaps and bounds. Four roller (rolling machine) in the molding of the molding machine has a vertical section consisting of vertical rollers, thereby improving the bad material deformation conditions, especially in the deep section of the molded product, to reduce the deformation of the additional friction, reduced energy consumption, but also help remove scratches, ensure the product has good surface quality. (Roll Forming Machine) cold-formed steel units that belong to this category molding machine, its products and production for a variety of special-shaped cross-section cold-formed steel products, there is a strong versatility.

Cold Roll Process

Cold Roll Process 英文 Many profiled sections can not be produced by hot rolling process method, you can use the roll (roll forming machine) technology methods to achieve, and a reasonable cross-section structure, high dimensional accuracy and good surface finish, thus building structure , automobile manufacturing, rolling stock manufacturing, power transmission and telecommunications towers, electronics, household appliances, furniture decoration industry are extensive use of various shaped cross-section (cold-formed steel) products, even with a lot of stainless steel products, organic coatings, bimetallic composite metal coating or molding steel as a raw material, which greatly enhanced the vitality of such products, (roll forming machine) can be good prospects of its development.
