Making History With a State-of-the-Art Roll Former Machine
Modern profiling comes from after World War II era with the introduction of the encoders, pneumatic presses, prepunching and in-line welding, as well as technology that allows the profiling painted metal. Gagged in the 1970s and 1980s made shots prepunching demanding, and tool change down-time has been reduced by the use of parallel rollers, raft building, and other innovations. Around 1990 Computer Assisted Roll former machine design systemshave been introduced, and since that time, many programmable controllers and computer systems have significantly increased efficiency and product quality.
An example is the double-sided roll forming mill, which is a duplex roll former upstream by a duplex roll former downstream followed on the same basis. The upstream mill controls the leg or flange height of slipped out and, while the downstream mill controls the width of the track in the same way. An example of this type of roles is the formerStudmaker that represents the latest technological innovations are changes in the level of the flange or the width of the track in less than twenty minutes. Steel studs can be manufactured at both the English and metric sizes without rolling or cut off the changes. The Studmaker is a pre-cut operation, which eliminates the need for die cut and diary pairs. Material of different sizes 12 to 20 gauge stud and different sizes of 3-5/8 inches to 14 inches, so the manufacturers to produceSteel frame, light, dry and load-bearing stud bolt, slip length and heavy-duty 12-gauge carrier, on the same machine with minimal changeover downtime. Minimize changeover downtime is especially cost effective for relatively small jobs – the Studmaker can in less than twenty minutes, during which former role requires older machines up to eight hours of setup time to make the same change can be converted.
New molding technology allows similar products – such as CEE and zee sections – will be producedon the same roles. This is achieved by dividing the mills along its middle, and the definition of flange, web and ear sizes with a control panel that can move the mill to change rafts sizes. It is even possible to change profiles in the press of a button. For example, the shape Purlinmaster cee purlins role and profile can be modified to form roll View zee purlins in only 7 seconds. In addition to CEE and profile zee purlins, this role also former lips and u-channel can produce profiles.Web-flange width and height in a few minutes instead of hours from the conventional rollformer not be changed. The Purlinmaster switch also has an auto-level function that allows the operator of a coil thickness to another without changing the tool at all – the new gauge can now be selected by the control of the operator console. The Purlinmaster can produce painted galvanized and hot-rolled steel purlins and black, with speeds up to 180 fpm and with a variety of holeStamping options for in-line flange and web punching of the highest precision.
