Details About the Forming Process of Metal Roll Forming Machine

Ⅰ. History of metal roll forming machine


Metal roller pressing forming machine processes materials into a variety of complex shapes of shaft, valve core and special fasteners and other products by virtue of the plasticity of the materials. Rolling deformation is a linear contact which continues step by step and requires small deformation force. A stroke can produce one or several workpieces.


Metal roll forming machines started in Europe in the 1960s. Due to the advantages of high production efficiency, economy of materials and enhancement of product strength, the metal roll forming machine is not only used in the threaded fastener industry, but also used in automobile, bicycle and other industrial sectors to process parts with complex shapes. With the development of technology and production, growing attention has been paid to metal roll forming machine.


Ⅱ. Features of metal roll forming machine


Metal roll forming machine process overwhelms cutting, grinding processes by its high efficiency, economy of materials, high product strength and stable quality. It is especially suitable for workpiece which is too long, too short or difficult to cut. For large quantity products whose annual output is millions, rolling forming process is the most beneficial and profitable.


Ⅲ. Materials and equipment of metal roll forming machine


Metal roll forming machine is a cold forging process. Materials for rolling forming are varies, among which low carbon steel is the common material for rolling forming, and non-ferrous metal is preferable.


The production of metal roll forming machine is generally by the cold heading machine upsetting forging out of the blank, and then by the thread rolling machine rolling processing. Equipment for thread rolling and roll forming includes all kinds of reciprocating plate rolling machine, planetary rolling machine, two-cylinder rolling machine and three-cylinder rolling machine. The most common type of roll forming is the reciprocating plate thread rolling machine. Therefore, it is only a matter of designing the mold of the metal roll forming machine for the manufacturers with cold and thread rolling machines.


Ⅳ. Process and mould of metal roll forming machine


On the metal roll forming machine,a movable wire plate and a fixed wire plate carries on the relative reciprocating motion. Metal roll forming machines is to roll different structural designs on the wire plate onto the workpiece.Various threads, convex rings, knurls, end chamfering, grooves of different depths and widths and other shapes can be rolled out as required.


Metal roll forming machines are more complex and demanding than rolling screw threads. Its mold design is according to the different shape of the workpiece, the screw board design into a section or several sections, in synchronous type or hierarchical type. When the diameter of the blank along the axis is the same or basically the same, synchronous rolling forming can be used; When the diameter of the blank parts along the axis is not the same and the diameter of several different structures need to be rolled, the classification type rolling forming is used. The general workpiece can be rolled into shape once, the ones with complex shape can also be rolled into shape twice.
