What's Uni Strut Channel?
Strut Channel is a standard cold roll formed steel used in electrical industry or constructions for structural support. Which is usually formed from metal coil strips, roll formed into an open channel section with lips to provide additional stiffness. The basis strut channel sizes are: 41*41. 21*21, and also some customized shapes.
Strut Channel Roll Forming Machine is to form 1.5mm-3.0mm strut channels with various types. The machine is able to produce 3 or more types of strut channel by adjust the roll forming mould. We have 2 design of the adjust method:
Adjust the spacers to achieve the type changing. The workers need adjust all the spaces of top and bottom rollers. the change over time is at least 6-8 hours.
Replace the whole roll forming mill. The roll forming mill will fastened on a mill base, and easy to replace. The changeover time is within 2 hour.
Punch Holes Types of Strut Channel Roll Forming Machine
An economical solution for punching holes, the speed is only 3-5m/min even though we use big pumps. It is easy to change the punch mould to change the holes punched. Sometimes we will choose the hydraulic station with storaging device to enlarge the speed of the punching.
Rotary devices usually consist of two working rolls. It is difficult to synchronize the surface speed of the rotary device with the speed of the roll forming mill. Therefore, in almost all cases, the rolls are rotated by the strip, which is pulled by the roll forming mill.
The advantages of the rotary devices are that they are considerably less expensive than the presses, they can run at any roll forming speed, and can repeatedly produce the same pattern within tight tolerances. The speed can be up to 30m/min
The disadvantage of the rotary punch devices are the holes position is fixed, only to change the rollers to change the holes.
Mechanical Punch Press
Presently, We always suggest buyers to use punch press for holes punch if the holes and its position is various. The speed of the punching is at least 20m/min which is based on the capacity of the press. The punch press alway work with a servo feed for punching precision holes position.
