The design principles of adjustable welding roller frame are as follows:

In order to meet the production needs, besides strictly abiding by the relevant mechanical design standards, we should fully consider the rationality and economic factors of the design, and design high cost-effective welding equipment such as welding roller frame.

Design of adjustable welding roller frame:

1. Each pair of roller racks consists of an active rack and a driven rack.

2. The driving frame is composed of a base, a roller support, a roller, a screw driver, a drive motor reducer and a control system.

3. The driven frame is composed of a base, a roller support, a roller, a screw driver, etc. (excluding the driving part).

4. The bottom seat is located at the bottom of the roller rack, which is used to bear the weight of the workpiece and the roller rack itself, and distribute these weights to the floor of the workshop to meet the load-bearing capacity requirements of the floor of the workshop. The base is welded by high quality steel plate and section steel, annealed after welding to eliminate welding stress of feed machinery, and then refined. It has the characteristics of high strength, good rigidity, long-term use, good deformation and shock absorption.

5. Roller support base is placed on the base, with positive and negative button screw installed on the base, screw mother fixed on the roller support base, and handwheel at both ends of the screw. The distance between the two rollers can be adjusted by the handwheel to meet the processing needs of workpieces with different diameters.

6. Roller is used to support workpiece and transfer torque, which is connected with the rotary shaft through key connection and installed at the end of the swing rack. The output torque of motor is transmitted to the roller through gear mechanism, and finally the workpiece is driven by friction force between the roller and the workpiece. The steel core is wrapped with polyurethane, the steel core is used to bear the weight of the workpiece, and the wrapped polyurethane part is used to increase the friction force, which can effectively prevent the slippage of the workpiece in the process of rotation.

7. Two sets of drive and deceleration systems are used to drive synchronously, which are respectively composed of three-phase AC motor, cycloid pinwheel reducer and turbine worm reducer. It not only embodies the high efficiency of the deceleration system, but also has good self-locking position function.

8. The roller rack is equipped with a mechanically fixed wheel-type anti-channeling device. When the cylindrical workpiece is welded on the roller rack, it can effectively prevent the axial channeling, and the axial channeling amount is less than or equal to 3 mm.

9. The center distance of each pair of rollers can be adjusted according to the diameter of cylinder workpiece to ensure that the wrap angle of the two rollers is larger than 45 degrees and less than 110 degrees.

10. The electronic control system is composed of electric box and wired hand-controlled box. It adopts variable frequency stepless speed regulation, with preset parameters and digital display, high speed regulation accuracy, and easy to maintain the consistency of processing specifications. Wired (15m) hand control box is used for remote control. It can perform forward and backward, speed regulation, start and stop actions. It is simple and convenient to operate. (The electric system can also be centralized controlled with the welding operator. The same control box is easy to operate.)

11. It has over-voltage protection, self-protection function, fault display and storage function, short circuit protection of automatic air switch, and preset parameters.
