Sales area Experience Machines produced 70+ countries 20+ years 1200+ sets Product Parameters Product Description Machine Components Components description of Purlin roll forming machine 1. Guide device Feeding material guide device, use high speed steel on both sides; its feature of High hardness, high wear resistance and high heat resistance to guarantee long life of machine. 2. Rollers of machine All Rollers are made from Cr12MOV.,Hardness 58-60HRC. CNC machines can improve rollers precision. Chromate finish on surface to add hardness of rollers. 3. High Accuracy Shafts Solid shafts dia. 82 or 90mm for different material thickness. All shafts are tooled twice by cylindrical grinding machine to ensure final precision. Guarantee buyers get high accuracy deck sheet from Zhongyuan made machine. 4.Design bearings inside forming rollers Design bearings inside the rollers to allow machine run with less loading so that rollers not easy to damage. Ensure the same speed between all the rollers, no speed difference between rollers, improve the forming accuracy. Bearings are helping to prolong machine life. Our made forming machines are allowed using more 15 years. 5. Main machine body Machine frame made from H450 type steel by welding,planned on surface to guarantee precision Side wall thickness: 45mm Motor Driving, Worm gear driving transmission, about 15-steps stations to form Main Motor=7.5KWx3, Frequency speed control All the screw bolts with grade 8.8(Some other factories use low grade4.8) to ensure fix the machine structure tightly and long life during the machine long time running. Forming speed 25-30m/min. All processed rollers are assembled on the carpet to avoid scratching on the rollers' surface. 6. Automatic Cutting system Automatic pre-cutting style, no need change cutter for different purlin sizes. All cutting frame are heat treatment to remove the original stress of steel, reduce deformation, improve stability Cutting tool material: Cr12MoV,hardness can reach 58-60Hrc. Machine can cut as buyers wanted sheet length,full automatically. 7. Automatic PLC Control System Control The Quantity And Cutting Length Automatically Input the production data(such as production quantity,Length,etc.)on the touch screen , machine can finish the set production plan automatically. One time buyer can set 20 batch data in the programme. Advantages of this purlin roll forming machine This purlin roll forming machine is one automatic purlin rolll former. When user wants to make different sizes of Cee or Zee or U shape purlin , people key in and then the control system adjusts
