Superda Fire Hose Reel Box Manufacturer Roll Forming Machine

Steel Enclosure Box MakingProcess

Uncoiler→ Straightening→Servo feeder→Hydraulic device

Explaination

This production line is equipment for production of distribution boxes. 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 0-13m, the box is cut and bent as required, and then manually packed away. This production line produces 2-3 enclosures per minute. the production box quantity speed according to different product specifications.
