2.2.4 Process and Features

Decoiler — Guiding —Feeding — Flattener —Roll Forming — Encoder — Straightener — run out table

1. This M/C adopts inner-expansion manual decoiler. The diameter can be adjusted through the adjusting bolt according to the coil’s inner diameter. The operation is quite easy. The decoiling speed is to the main machine’s forming speed.

2. The main frame is structured by welding entire T shape steel. The side stands are welded on the frame, and to clear the stress by vibration in order to maintain the rigidity and stability of the machine.

3. This machine has 7-roller flattening system. Two of the rollers are hold-feeding rollers. All the rollers are made from 40Cr advanced alloy steel after heat treated and chrome plated. The feeding rollers are connected with the motor and provided with manual clutch. The strips from the coil are always tightened in the flattener for a better flattening effection.

4. The forming rollers are made of GCr15 bearing steel through a series of heat treatment such as forging, distressing anneal, high frequency hardening(the degreed is 8-10mm), backfiring, phosphorization etc. The surface of the rollers can reach the rigidity of HRC58-62. All the forming rollers are process on CNC lathe, by which the accuracy can be guaranteed.

5. The main shaft is made of 40Cr advanced alloy steel after a series of heat treatment such as high frequency hardening, quenching and tempering etc and processed on lathe, burnishing the surface, wire cutting the channel to make it high accuracy and large capacity.

6. The shifting of sizes to be carried out by changing the semi-circle spacers which is produced by wire-cutting. It can be easily finished and this may save time and labor force.

7. A straightener is fixed after rollforming which can be adjusted according to the users requirements. This section is used to control the quality when the material is not qualified.

8. The punching section is highly automatized. It controlled by PLC and can reach the punching requirements of process installation holes. It is made from professional mould material GCr12 cold punching steel after heat treatment and cold punching process. The position of holes in length direction can be adjusted on PLC.  The hole’s position in wide direction can be adjusted by screw.

9. Cut to length is the last process of this machine line. It cuts accurately to any length you set on the PLC. The cutter consists of Hydraulic diver, profiled blade and cutter frame. The blade is made from Cr12 cold punching steel after strict process. It adopts 45 degree staggering cutting. This costs no waste and can hold the cutting profile a good shape. And this cutting is of high accuracy.

10. The machine adopts Siemens PLC, Mitsubishi, touch screen, Transducer and encoder. The entire electric components are of Schneider or Siemens.
