Production requirements of Fengwei welding rotator
1. The welding rotator is composed of an active frame and a driven frame. The main and driven frames have two rollers. The main double motor is driven by two wheels. This method has a larger driving torque than a single motor and can ensure the rotation of the workpiece. smooth and stable operation.
2. The base of the main frame and the driven frame are all made of tailor-welded structure, with different numbers of reinforcing ribs welded. The overall structure has good rigidity and strong torsion resistance.
3. After welding, the main frame and the driven frame are subjected to the overall stress relief treatment, and they are machined to ensure long-term stable operation.
4. Each shaft hole of the swing arm of the roller frame is formed by one-time loading on the boring machine, with high concentricity and flexible rotation of the roller.
5. The roller cores of the active frame and the driven frame are steel wheels, which are processed and formed after heat treatment.
6. The roller adopts the all-plastic combination method. The steel core roller is covered with heat-resistant rubber, which has a large bearing capacity and a long service life of the rubber layer, which is not deformed or degummed.
7. According to the diameter of the workpiece, the user can adjust the distance between the two wheels through reserved screw holes to adapt to the change in the diameter of the workpiece.
8. The AC frequency conversion technology adopts the stepless speed regulation, and the imported frequency converter is selected. The low-speed torque is large, the performance is excellent, the speed regulation range is large, and it has multiple protection functions of overcurrent, overvoltage, and overload.
9. The reducer adopts a high-quality cycloidal pinwheel reducer, adopts a planetary reducer transmission structure and rolling contact method, which has the advantages of small size and durability, and at the same time, the efficiency loss is small, and the mechanical efficiency is as high as 90%.
Manufacturing Requirements for FENGWEI Welding Spinners
1. The roller frame can automatically adjust the swing angle of the wheelset according to the diameter of the workpiece, and can automatically adjust the center. When matched with a welding manipulator and a welding power source, the inner and outer longitudinal seams and inner and outer circumferential seams of the workpiece can be welded.
2. The transmission noise is low and the workpiece rotates smoothly, which can realize the welding, polishing, rubber lining, and assembly of the cylindrical cylinder. The rotation speed of the roller should be stable and uniform. Crawling is not allowed.
3. It must have overvoltage protection, self-protection function, fault display and storage function, automatic air switch short-circuit protection, and preset parameters.
4. The heights of the main and driven rollers can be adjusted appropriately, and the assembly and welding of the cone and segmented unequal-diameter revolving bodies can also be carried out.
5. For some non-circular elongated welding parts can be clamped in a special ring clamp, and the welding operation can also be carried out on the welding roller frame.
6. The self-adjusting roller frame adopts digital adjustment and display technology for the speed of the roller, and the setting of the welding speed is very intuitive and accurate, which reduces the difficulty of operation for workers.
7. The manufacturing and assembling accuracy of the roller frame should meet the 8-level accuracy requirements in the national standard. The roller frame should be made of high-quality steel. If a base of welded construction is used, a stress relief heat treatment must be performed after welding.
8. The roller frame must be equipped with a reliable conductive device, and the welding current is not allowed to flow through the bearing of the roller frame.
9. When the cylindrical workpiece is welded on the anti-axial movement roller frame, the axial movement of the workpiece during the whole welding process should be ≤±3mm.
10. The center distance of each pair of rollers of the roller frame must be adjusted according to the diameter of the cylindrical workpiece to ensure that the wrapping angle between the two rollers is 45° larger and less than 110°.
11. Equipped with 15m control cable, roller forward and reverse switch, near control, and remote control switch.
12. The rollers are preferably made of polyurethane or nitrile rubber.
Safe operation of FENGWEI welding spinner
1. Check whether the welding rotator control box and welding rotator can be grounded before use, and cannot be used without grounding.
2. Non-professionals are not allowed to debug and maintain the frequency conversion processing unit in the control box of the welding rotator.
3. The control box, remote control box, and connecting wire of the welding rotator shall not be pulled or crushed by heavy objects.
4. The control box of the welding rotator and the welding rotator shall not be placed in an environment of harmful industrial gas or flammable gas, and the body shall not be exposed to moisture, drenching, or exposure to the sun, and should be placed in a ventilated, dry, and dust-free place.
