1) Introduction:

The profile forming process: Passive decoiling--- 15T hydraulic hole punching, reinforcing bid pressing---material feeding--- roll forming--- straightening--- hydraulic cutting off---- material unloading, all the process finished automatically.

2) Construction:

The whole line is composed by decoiler, hydraulic punch press, feeding device, roll forming machine, straightening device, hydraulic cutting off, cold water recycling device, pneumatic and electric control system, etc.

3) Decoiler (as drawing)

Bearing 1T, Inner diameter φ450-530mm, out diameter φ1200mm.

4) Rack

a. One piece construction, the roll forming device, straightening device, cutting off device is a whole unite. The rack receives heat treatment after welded, fine finished surface, which ensuring the intensity, rigidity, stability and accuracy of the machine.

b. All the components of the machine received necessary surface treatment according the actual working situation and environments, like electroplating, hardening, etc to ensure the enough rigidity and surface function of the components.

5) Feeding device: synchronism adjusting rollers.

6) Punching Machine

This line equipped with 15T hydraulic punching machine.

7) Roll Forming Machine

Roll Forming rollers: material GCr15, hardness after heat treatment HRC48-50, hole diameter (roller shaft diameter) φ42mm, the min. outside diameter of rollers isφ100.

8) Transmission Device: (as drawing)

a. Main motor (Jiangmen Jiangyan motor), Frequency control.

b. The driving rollers are driven by three sides belt, the passive rollers are driven by gears, with center distance a=75, reduction ratio i=30 worm gear case, gear mould m=5. Main side plate thickness: 30mm, deputy side plate thickness: 25mm. Finished by six sides grinding and boring holes treatments.

c. The material of main shaft is 40Cr, finished after heat treatment and refine grinded.

9) Hydraulic Cut Off device: (as drawing)

a. Hydraulic system: the system has unloading protect function, the hydraulic components use Taiwan Dazheng brand.

b. Mould rack: the mould plate closed height is 260mm, the adjustment range of the closed height is 20mm, the max. stroke of oil cylinder is 100mm.
