1, Twin cantilevers gear drive, the width can be adjusted through one side of the machine by manual, different type also can changeable faster. 2, Insert the sheet plate which already perforated into the machine, through nine stations to roll as the cable tray. It consists with the speed regulation alternating current machine, reducer, gearbox(left and right side), the crosswise adjusting mechanism and one complete set of rollers. One set of roller can complete all type of the cable tray, type change can through the adjustment of the one side of machine by manual The main body and the gearbox use the welding structure, de-stressing processing; the material of the gear is the 45 steel hard tooth surface.3, The roller uses the combinated structure, the speed difference and the forming resistance are small, the steel plate surface will be less wear; and also guaranteed the precision shape of the working piece with no scratch . 4, The material of the roller is the GCr15 forging, after whole quenching then by numerical control processing, degree of hardness can reach HRC58-62; Has the characteristic with high strength, hardness, precision and long service life etc. 5, main technical parameter1)Forming station: 9 stations ( double row) 2)Main power: 18.5kw speed regulation motor 3)Forming speed: 18-25 m/min 4)Outlet of the equipment: about L4mXW1.8mXH1.4m 5)Rolling specification of the product:
