TF Locomotive Stainless Bottom Frame Curb Girder Roll Forming Line

Product Introduction

TF locomotive stainless bottom frame roll forming line consists of uncoiler, feeding guider, lubrication device, quick-change cassette, cutter, hydraulic and electric control system.

Equipment overview:

Production flow: uncoiler- guider -leveler- roll former-cutter- discharger- hydraulic system.
Because the line is equipped with quick-change cassettes, various kinds of high-precision stainless profiles can be produced. Specification of the material is SUS301-DLT/MT/HT. The whole line operation just needs one operator. Many sets of final product length can be set at one time, automatic producing, and remote control. Final products length: 20m with high straightness accuracy. Those products can be widely used in the locomotive body of the metro and light rail system.

The main machine consists of a torri rack, machine base, transmission system, rollers. The transmission system consists of the main motor reducer, gearbox. The main reducer is installed in the middle of the machine.

The structure of the rollers is combined, so the line speed difference and resisting force of roll forming are small. The roller through quenching and processed by the high precise CNC lathe; the roller surface with a mirror face treatment to reached long time using. All these assure the accuracy and stability of the roll forming.
The roll forming craft is made by the special Germany cold roll forming program COPRA; the craft is also made the FEA analysis and check.

Equipment overview:

Production flow: Uncoiling- connection bridge feeding -Longitudinal intermittent roll forming- press, notch& cut-discharging
Main machine consists of torri rack, machine base, transmission system, rollers. Transmission system consists of main motor reducer, gear box. Main reducer is installed in the middle of machine.
Transmission mode: Main motor→ gear reducer→ transmission umbrella gear→ shaft joint→ torri down shaft

The structure of the rollers is combined, so the line speed difference and resisting force of roll forming is small. The roller through quenching and processed by the high precise CNC lathe; the roller surface with mirror face treatment to reached long time using. All these assure the accuracy and stable of the roll forming.
The roll forming craft is made by the special Germany cold roll forming program COPRA; the craft is also made the FEA analysis and check.
The whole line adopts PLC control, human and machine screen. The whole line is with emergency stop, in order to protect the human safety.
