Both sides of the forming parts composed by fourteen rollers, one side for forming flange, the other side for forming hook, the forming rollers are made of GCr15 bearing steel through salt bath heat treatment and finishing, durable. All the shafts and gear are heat treated to ensure the use performance and life; Each tail has a shape-adjusting device to ensure the flange in line with the requirements. The side plate is made of forged steel and finished; TDF flange forming machine have fourteen group forming shafts, and each shaft is equipped with a drive gear and left and right rollers. The left side is hook roller group; the right side is the flange roller group. In addition, the right side flange forming a part has a rubber material-holding wheel and a feeding car to ensure the whole forming course stable, and produce the qualified products.
Matters Need Attention
1) On the upper side plate TDF flange forming machine is double end studs ④ and disk spring the gap between the upper roller and bottom roller can be adjusted automatically according to the rolling thickness. Such as T-12 machine, plate thickness between 0.6-1.2mm.
2) All new flange machine has been adjusted and qualified before ex-factory, if necessary, only need to adjust the feeding plate, four studs ③、④ do not easily adjust or move.
Lifting and Installation of TDF flange forming machine
- Ensure no component losing or omitting during transportation; Carefully check whether all relevant parts are complete and intact before installation.
- The lifting device shall be carefully checked and ensure it complies with requirements before lifting machine, at least two slings, and equal in length, during the lifting process, the lifting hook point shall be kept on the center position and keep a good center of gravity to avoid the machine lost the center of gravity and flip. When unloading, slowly put the machine on the flat ground, four-foot ground first, no one hanging in the air, put bearer if necessary, the machine can’t be tilted or side standing, otherwise, the machine will be deformed and affects the machine use function.
- The machine shall be installed on the level hardened ground.

Flange Forming Machine Lubrication
Lubricating according to the following requirement:
|No.||Lubrication Parts||Lubricating Oil||Lubrication Time|
|1||Gear and drive chain||Grease||Every working 40 hours|
|2||Ball bearing and a plane bearing||Grease||Every working 40 hours|
|3||Drive chain wheel||Light lubricating oil||Every working 80 hours|
|4||Transmission chain wheel||Light lubricating oil||Apply the lubricant to drive chain|
|5||Speed reducer||Gear oil||Replace oil once every three months|
Adjustment and Operation
- Check before starting the machine
- Filling lubricating grease or oil according to the requirement
- Thoroughly check each part, such as tensioning chain, drive belt tension condition, leakage protection, fastening bolt, ensure all parts in good condition.
- Idle working for several minutes for inspecting the machine running conditions
- Inspect the TDF flange forming machine running direction, if wrong, adjusting back to the right direction
- Check each fastener, if became loose, eliminate unsafe factors.
- Listen carefully and attentively, ensure no abnormal noise
- Applying lubricating oil/ grease to all bearings, gear, transmission shaft and screw
- Check whether the electric system is safe and reliable or not
- Check whether the guard shield is reliable or not
- The use of auxiliary feeding trolley depends on the plate width and flange width. When the plate length less than 180mm, feeding trolley is necessary, put the plate on the trolley fastening with two clamps and put forward by workers during the rolling process. Is the plate length less than 180mm, the trolley can be dismantled from the sideways and put on an appropriate place.
The first time use, measure and check the results, if the bilateral sides are unequal, adjusting the stopping plate position and the parallelism between the material guide plate and feeding direction; If the large right-angle edge of the flange is larger than 90°, adjust the holding rubber wheel down and increase the holding force. If the flange curving upward/down, adjust the shape-adjusting wheel up/down.
The machine used for forming through folding, can’t be used as Casting Rolling Mill. Therefore, a certain gap (approx. plate thickness plus 0.1-0.2mm) between upper, middle and lower rollers is necessary, the gap has been adjusted before leaving factory, users shall not arbitrarily turn the countersunk head screws ③fastening bolt ④ and disc spring ( see figure 2 and 5 )
Gap variation caused by loosened bolt nut ③ and screw ④ or other reason need adjusting. First, loose all nuts④, put a plate with gap same thickness between the rollers and adjust the screw ③ until the gaps between four-side rollers almost same, then tighten the nut ④[δ=Min. plate thickness+0.1-0.2], if want the Min plate gap, leave a slight space will be OK.
- Bone-shape adjustment
Loosen the screws on leading-in positioning plate and move the plate in the direction parallel to the slot to accommodate a sheet of different widths or different thickness, then tighten the guiding plate.
In the production of the flange, if the sheets are thin, flange side hook size is not enough, slightly move the flange side feeding plate to the inside.
- The TDF flange forming machine shall be operated by the professional operator, who should very familiar with the machine structure and performance and qualified after training, and in strict accordance with the< safety operation procedures>.
