General Manufacturing Process of Roof Roll Forming Machines

General Manufacturing Process of Roof Roll Forming Machines

 1. Machine Frame Manufacture

H-shaped steel welds the frame according to the drawing------>Remove welding slag------>Fill the welding pit with special mud------>Grind all welding points again------>Coat the machine frame (spray anti-rust paint once, topcoat twice).

 

2. Forming Rollers

Cut the round steel into the correct thickness according to the design drawing------>Rough lathe----->Fine lathe----->Fine polish----->Hard chrome plating----->Polishing------>Add lubricating oil for rust prevention.

 

3. Forming Shaft Processing

Cut the solid round steel into the correct length according to the design drawing----->Rough lathe----->Quenching and tempering----->Precision lathe----Polishing.

 

4.PLC Control Cabinet

Design the control program according to the required actions ------>Make the cabinet cover ------> Connect the inverter, PLC, touch screen, relay, etc. in the cabinet according to the electrical design drawing------> trial the programs and adjust all actions match well with roll forming machine producing line.

 

5. Hydraulic System

Design the hydraulic system according to the required actions of the production line------> Connect the hydraulic pump, oil pipe, and valves according to the system requirements.

 

6. Installation of the Entire Roll Forming Line

1) Install the rollers of each station on the shaft according to the mechanical design drawing.

2) Install the lower shafts on machine frame.

3) Lift the upper shafts on the frame.

4) Find the center line of this roll forming machine.

5) Connect all electrical systems and hydraulic systems for the roll forming machine line.

6) Switch to manual mode on the PLC control cabinet and slightly adjust the rollers of each station to put them in place according to the design drawing.

7) Run the first piece of metal roof to try and find out where the small problem occurs. If necessary, adjust it a little bit.

8) After all stations are adjusted, run another piece of metal roof to see if it needs to be adjusted and repeat step 7.

9) Test the cutting blade and check whether the cut position is beautiful.

10) When the size and the steel roof sample shape are correct, and the cut effect is good, we can adjust the correct roof length on the PLC control system. If the length is incorrect, reset the parameters on the touch screen.

11) After the roof sheet roll forming machine line runs normally in manual mode, we can switch to automatic mode on the PLC control cabinet, try to produce a few pieces of roof and compare the length again, overlap again.

12) Finally, the roof panel roll forming line is completed and ready for customer inspection in our factory.
