This production line is equipment for production of distribution box using panels such as door panel, bottom panel, install panel or named as mounting panel. The strip coil to be processed is manually placed on the uncoiler, and then corrected and tensioned. After leveling, it enters the hydraulic pre-punching and punching notch, and is sent to the forming machine by the guide device to form. Under the frictional damping action of the forming roller and pressure roller, after entering the bending part at a linear speed of 0-8m. the production panel quantity speed according to different product specifications.

B: Roller (roller staiton): 12 sets of roller forming, high-quality Gr12 mold steel, HRC up to 58 ~ 60º are processed by precision CNC machine tools, precision is 6 ~ 7, surface roughness is above 0.8, no scratches on the surface.

C: Transmission part: It is the conveying part of the forming power of the production line. The power is transmitted from the main motor to the reduction gearbox, and then transmitted to the driving wheel by the gearbox through the gearbox.

3. Fixed-length bending part: It consists of fixed-length device and bending mechanism. The fixed-length device uses a laser probe combined with an encoder to fix the length. When the sheet reaches the fixed length, the bending product is controlled by the PLC.

4. Electric control system: The entire production line adopts centralized control, the components are imported and domestic high-quality products, or specified by customers, and the standard components are Taiwan brand. The installation of the equipment's electronic control components complies with national regulations, with clear line numbers, reasonable bureaus, clean control panels, and clear labels.

5. Security protection: The host is equipped with a protective net, and warning signs are set on the parts involving personal safety. The electrical appliance has reliable safety grounding, and the emergency stop button is also provided on the die end to protect personal safety to the greatest extent.
