4.1.1Technology process of the machine

 Automatic feeder(5T) → leveling → Servo feeding→ punching  → roll forming machine → re-forming → following hydraulic cutting → output

4.1.2Main parts technology specification

  4.1.2.1  5T Automatic hydraulic feeder

A. Inner diameter of the steel coil：φ508mm；

B. Harmomegathus range of inner diameter: ф480-520 mm；

C. Max diameter of steel coil:φ1000mm; Load capacity：≤5T

D. Way of expansion：5T hydraulic automatic

4.1.2.2   Leveling machine

a.Working roller：9 rollers leveling machine

B. Features of structure：Leveling rollers rigidity and surface roughness mechanical property are improved after hardening and tempering and chrome finish. It is including the pinch roll and leveling roll, pinch roll can be adjusted separately, leveling up roller adopt massive structure, establish two adjustment points on front and back to form certain oblique angle, it can easy to improve the quality of leveling. There is a pair of guide flat rolls and two pair of guide vertical rolls on the feeding side of the leveling machine, guide vertical roll can be centring move.

a.Function：Feeding

b.Features of the structure：Using servo motor drive 3KW. Multiple stage feeding：It can input 10 groups different feeding length. The touch screen display is easy to change and set up the technical parameters. Automatic induction actuating system is linkage with the punching machine. ( control the punching machine start.)

4.1.2.4  Punching machine

80T high speed punching machine, working speed is about 15-20m/min

4.1.2.4 Roll forming machine

Main data

2.        Roller QTY：20 groups（Including 1 gear milling）

3.        Working speed：15-20m/min

4.        Material of roller：GCR15，CR12MoV quenching

5.        Drive type：Memorial archway gearbox drive

6.        Diameter of main shaft：￠90mm

4.1.2.5  Following cutting

a.Type：Pneumatic following, mould cutting

b.Feature of structure：Following cutting is separate mechanism, by PLC main computer to fix the length, cutting length can be fixed according to the requirement. Using non-stop following cutting technology. The cutting face is not easy to be out pf shape, working efficiency is high.

4.1.2.6  Electronic control system：Kunlun Kuntai 7inches touch screen, Siemens PLC，Yaskawa frequency converter, Schneider low-voltage apparatus.

a. The whole line uses PLC control, Liquid crystal touch screen, human-computer interface to realize the interaction between the PLC and human. Operator via the setting procedure to automatic operation and monitor the control process to realize that the operator control the whole line and change the control parameter, and monitor the running status, parameter and failure indication of the equipment. Length of the work piece is set by digital, the length of the work piece can be adjusted.

b. Operating mode is including manual/automatic. The machine has manual and automatic switch function. The machine is stand-alone run within the manual status, it is easy to maintain. Within the automatic status to proceed the whole line running, sequence start-up. The whole has jerk button in order to handle the emergency episode, which can guarantee the machine and operator safe.
