Round Duct Machine factory The pre-bending function makes the straight side narrower, and even a small round tube with a diameter of 100mm can be rounded. It can be used to produce round air pipes with round air pipe lock stitching machine and round air pipe lock sewing machine. Combined with manual worm gear and eccentric gear device, the machine can quickly move the side rollers up and down to improve efficiency. The plate rolling machine adopts a precision indexing mechanism structure to ensure the synchronization of the three rollers working at the same time. The vertical movement of the bottom roll and the side roll is controlled by the lifting screw to realize rolling of different diameters. Round duct processing machines include electric plate bending machines, round duct lock forming machines, round duct seaming machines and round duct grooving machines. All these machines can make a complete circular duct. The round duct processing machine produced by SBKJ is very suitable for making small round ducts and non-standard round ducts, and has the advantages of economy and efficiency. SBKJ company specializes in the production and sales of ducts II, III, IV, V, CNC angle steel flange production lines, cutting, folding, machines, bending machines, duct zippers, spiral forming machines, CNC plasma cutting machines, pipe bending machines, TDF method Lan machine, slotting machine, sliding roller machine, etc. Each piece of equipment in the round duct processing machinery is developed in strict accordance with the corresponding requirements from the aspects of rolling, locking, closing, leveling, crimping, etc. Each round duct processing requires a corresponding machine to Maximizing the processing efficiency also reduces the customer's use cost and we have high quality requirements for ourselves. All our mechanical parts use the best quality brand suppliers to ensure the stability and quality of our products.Round Duct Machine factory website:http://www.spiraltubeformer.com/round-duct-making-machine/round-duct-machine/
