 Hydraulic power driver of the CZ purline machine

A Power Drive Unit is used to convert electrical or hydraulic power into mechanical motion (often rotary) and drive a mechanical actuation system

Hydraulic CZ purlin machines use liquid fluid power to perform work.  In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes.

Hydraulic systems, like pneumatic systems, are based on Pascal's law which states that any pressure applied to a fluid inside a closed system will transmit that pressure equally everywhere and in all directions. A hydraulic system uses an in-compressible liquid as its fluid, rather than a compressible gas.

The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power, and the huge multiplication of forces that can be achieved by applying pressures over relatively large areas. One drawback, compared to machines using gears and shafts, is that any transmission of power results in some losses due to resistance of fluid flow through the piping

Change using automatic system

According to your section profile, size range, thickness range we could provide you different solutions of purlin roll forming machine to manufacturer a complete range of structual purlins(height and width change using automatic system by motors):

Only to produce C/U section, change time: few seconds

C/U/Z section-manual change whole line from C to Z, change time: 10 minutes

C/U/Z/M section-manual change 4 stations from C to Z, change time: 2 minutes

C/U/Z/M section-automatically change from C to Z, change time: few seconds

Regarding the cutting unit ,you can choose the pre-cut, post cut or both. Gearbox driving system with cast iron stands are more durable and recommendable.

If you only need to produce few sizes, we also suggest manually change sleeves, it’s more affordable.

We make different solutions according to customers’ drawing, tolerance and budget, offering professional one-to-one service, adaptable for your every need. Whichever line you choose, the quality of Zhongtuo Machinery will ensure you obtain perfectly functional profiles.
