    Self-adjusting roller racks and adjustable roller racks are indispensable welding auxiliary equipment in industrial welding production, but do you know the difference between them? Today, Yunkang Welding will talk to you about this topic.

Features of self-adjusting roller frame

1. Automatic adjustment function

    The self-adjusting roller frame has a significant automatic adjustment function and can automatically adjust the swing angle of the roller group according to the diameter of the workpiece, eliminating the need for tedious manual adjustment operations. This feature enables it to quickly adapt to workpieces of different sizes in practical applications, improving work efficiency.

2. Transmission mode

   The active roller of the self-adjusting roller frame adopts gear meshing transmission, which has the advantage of strong driving ability. The motor drives the active wheel through the transmission system, which can stably transmit power and ensure that the roller frame can smoothly drive the workpiece to rotate during operation. As mentioned in the performance and characteristics of the self-adjusting roller frame, the active roller adopts gear meshing transmission, which has strong driving ability and ensures the efficient operation of the equipment.

3. Roller type

    The roller types of self-adjusting roller racks are diverse. Steel-rubber combination rollers are widely used in general, while all-steel rollers are used for large-tonnage workpieces to ensure their large load-bearing capacity. For example, the self-adjusting welding roller rack of Yunkang welding uses steel-rubber combination rollers, and all-steel rollers are used for large tonnage, which have large load-bearing capacity and strong driving ability. This design can meet the needs of workpieces of different tonnages and improve the applicability of the roller rack.

4. Speed regulation performance

    The self-adjusting roller frame is equipped with a variable frequency speed regulator, which has the characteristics of wide adjustment range, large starting torque and high adjustment accuracy. The variable frequency speed regulator can accurately adjust the speed of the roller according to actual needs to meet the requirements of different welding processes.

5. Operational characteristics

    The self-adjusting roller rack is easy and reliable to operate. Users can easily operate it without professional technical knowledge. Its operation is simple and intuitive. Through the control components such as the speed knob, the speed adjustment and operation control of the roller rack can be easily realized. For example, the self-adjusting roller racks produced by many manufacturers emphasize the characteristics of easy and reliable operation, which brings great convenience to users.

Features of adjustable roller frame

1. Adjustment method

    There are three types of adjustable roller racks: manual screw adjustable, manual bolt shift, and electric slide shift. Among them, the manual screw adjustable type adjusts the roller center distance by rotating the screw to adapt to workpieces of different diameters; the manual bolt shift type changes the roller center distance by adjusting the position of the bolt; the electric slide shift type uses an electric device to drive the slide to move, thereby adjusting the roller center distance. This diverse adjustment method can meet the needs of users in different scenarios.

2. Drive mode

    The drive adopts cycloid pinwheel reducer or worm gear reducer, dual motor drive. Cycloid pinwheel reducer has the advantages of high transmission efficiency, low noise and long life; worm gear reducer has self-locking function, which can ensure the safe operation of the equipment to a certain extent. Dual motor drive can provide greater power to ensure that the roller frame can stably drive the workpiece to rotate.

3. Roller type

    According to user needs, rollers are divided into three types: rubber wheels, steel wheels, and steel-rubber combination wheels. Rubber wheels have the characteristics of good elasticity and high friction, and are suitable for some workpieces with high surface requirements; steel wheels have the characteristics of high hardness and strong load-bearing capacity, and are suitable for large-tonnage workpieces; steel-rubber combination wheels combine the advantages of steel wheels and rubber wheels, and have a certain load-bearing capacity and can provide good friction.

4. Scope of application

    It is mainly used for welding, polishing, rubber lining and assembly of cylindrical barrels. It can also be used in conjunction with other tooling for the assembly and welding of cones and segmented unequal diameter rotating bodies. In the welding of cylindrical barrels, the adjustable roller frame can make the barrel rotate evenly and improve welding quality; in the polishing and rubber lining process, the roller frame can provide stable support and rotation power to improve work efficiency; when used in conjunction with other tooling, it can adapt to workpieces of different shapes, expanding the scope of application of the equipment.

Summary of the difference between the two

    The self-adjusting roller frame mainly relies on the automatic adjustment function to adapt to the change of workpiece diameter, while the adjustable roller frame adjusts the roller center distance through a variety of manual or electric methods.

    In terms of transmission method, the active roller of the self-adjusting roller frame adopts gear meshing transmission, which has strong driving ability. The motor drives the active wheel through the transmission system to stably transmit power. The adjustable roller frame is driven by a cycloid pinwheel reducer or a worm gear reducer, with dual motor drive. The cycloid pinwheel reducer has high transmission efficiency, low noise and long life. The worm gear reducer has a self-locking function to ensure the safe operation of the equipment.

    In terms of speed regulation performance, the self-adjusting roller frame is equipped with a variable frequency speed regulator, which has a wide adjustment range, large starting torque, and high adjustment accuracy. The adjustable roller frame adopts DC servo motor driven PWM speed regulation, or AC asynchronous motor driven variable frequency speed regulation, with a large speed regulation range, stable rotation, and the welding speed can be preset and digitally displayed.

    In terms of operation characteristics, the self-adjusting roller frame is easy and reliable to operate. Users can use it without professional technical knowledge. Speed adjustment and operation control can be achieved through control components such as the speed knob. The adjustable roller frame has three adjustment methods: manual screw adjustable, manual bolt shifting, and electric slide shifting. The operation is relatively complicated, but it can meet the needs of different scenarios.

    Both have their own advantages in different application scenarios. Self-adjusting roller stands are suitable for situations where ease of operation is required and the diameter of the workpiece changes frequently. They can quickly and automatically adapt to workpieces of different sizes to improve work efficiency. Adjustable roller stands are suitable for situations where the adjustment accuracy of the roller center distance is required to be high, and where multiple adjustment methods are required to meet the needs of different workpieces, such as the assembly and welding of cones and segmented unequal diameter rotating bodies in conjunction with other tooling.
