TK3A TK5A Hollow Elevator Guide Rail Cold Roll Forming Machine Features

  • This kind of roll forming machine is suitable for TK3 TK3A TK5 TK5A hollow guide rail and escalator guide rail, customers need provide their guide rails drawings.
  • When producing hollow guide rails and escalator guide rails of different specifications, worker just need change machine rollers.
  • The whole line adopts PLC control, LCD touch screen and human-machine interface. Realize the interaction between human and PLC. The operator can automatically run (programmable control) and monitor the control process through the set program, so as to realize the operator to control the production line and modify the control parameters, and monitor the equipment operation status, operation parameters and fault indication in real time. The length of the work piece can be adjusted. Real time monitoring of equipment operation status and fault indication.
  • There are two operation modes: manual and automatic. It has the function of manual and automatic switching: in the manual state, it can operate a single machine for maintenance; in the automatic state, it can operate the whole line for production and start in sequence; the whole line is equipped with an emergency stop button, which is easy to handle emergency accidents and ensure the safety of equipment and operators.
  • Manual operation panel is set beside the machine to facilitate the operation of workers.

Our TK3A TK5A Hollow Elevator Guide Rail Cold Roll Forming Machine Advantages

1.The production line is driven by Japanese servo motor, which can set various specifications and output products according to customers’ needs. When it is necessary to produce products of different lengths, it is only necessary to select them directly on the computer touch screen without mechanical adjustment. The real significance is to realize the humanized intelligent menu management function, which greatly improves the production efficiency and reduces the production cost, scrap rate and labor intensity. Multi station operation is adopted, and the main operation platform is set between the hydraulic press and the molding machine. It is equipped with a hand-held controller, which makes the operation more convenient and improves efficiency. There are alarm functions such as material shortage shutdown, counting, output reaching shutdown, abnormal transmission, emergency stop, clamping, limit, etc.
2. Equipment processing capacity: 2.2mmm (cold rolled strip);
3. Forming speed: 6m / min;
4. Processing length: 800 ~ 3000mm;
5. Length accuracy: l ≤ 2000mm; ± 2mm;
6. Straightness, interference: l ≤ 1000mm, bending not more than 2mma

Finished Products

Cold Roll Forming Machine Section Description

1) Servo motor power: 15kw 

2) Gearbox: K series. K series spiral bevel gear reducer, with large torque and small power loss, is suitable for full load and high strength operation. Eliminate the old cycloid reducer. 

3) Transmission mode: gearbox transmission. 

4) Frame base: it is welded with 400H section steel and reinforced bar is welded in the middle. Stress relief after welding.The whole upper surface of the frame is milled and planed by CNC gantry to ensure all datum planes.

5) Archway structure. Archway material: ball mill cast steel casting, CNC finishing.

6) Welding materials: the frame and structural parts are welded with flux cored gas shielded wire (only one in the industry), so as to ensure the structural strength and mechanical properties meet the ship component standards.

7) Main shaft: shaft diameter: φ 70mm. Material: high quality 40Cr. Modulation processing. Tempering hardness: HRC: 250-280. After CNC finishing, the outer circle is ground.

8) Roll: the material is forged by single piece of high quality GCr15 and Gr12 materials, which makes the internal crystal of the material change, the density is higher, the wear resistance coefficient is improved, and the service time is longer. Two times of quenching for the roll finishing turning. Quenching hardness: HRC58-62. Hard Cr plating, coating thickness: 0.05mm. The friction coefficient between the roller surface and the rolling material is reduced, and the galvanized layer is not damaged in mechanical properties as far as possible.
