welding rotator

Welding rotator absorbs the advantages of similar products at home and abroad, and is designed and manufactured according to the use requirements of pressure vessel manufacturers. This product is practically used for manual welding and automatic welding of metal cylinders and is necessary equipment for manufacturing pressure vessels. It has the advantages of advanced technology, reliable quality, and simple operation. This welding rotator can be divided into adjustable and self-adjusting welding rotators, which can be applied to products with different diameters within the specified range and can achieve stepless speed regulation under the specified range of welding parameters, with low transmission noise and smooth working rotation.

The roller set adopts a combination of steel and rubber, which has a large pressure bearing capacity and long life of the rubber wheel. The main drive worm adopts ZC arc-tooth cylindrical worm. The tooth surface of the worm is quenched and ground. The load-bearing capacity is twice that of the general cylindrical worm. It has high efficiency and long service life. The base is equipped with a scale, and the user can according to the diameter of the cylinder. Adjust the distance between the two wheels.

It adopts ordinary Y series AC motor, which is easier to maintain and smaller than a DC motor, and its appearance is changed beautifully. The frequency converter is a new generation of energy-saving products, digital display: speed, frequency, nature of the fault. The operation on the electric control box and the remote control can be operated at any position, and the remote control is set with a digital display. Synchronous linkage with the operation.

Choice: A set of welding rotators consists of one active and one passive. The active welding rotator is generally selected at least twice the actual weight of the workpiece. When the workpiece is special, you can choose one active welding rotator with multiple passive welding rotators, or multiple active welding rotators with multiple passive welding rotators.

Self-adjusting welding rotator

The center distance of the rollers is automatically adjusted to meet the needs of workpieces with different diameters, and it is easy to use.

There is a rail positioning groove under the bottom plate of the welding rotator machine base, which is convenient for the centering and positioning of the main welding rotator and the welding rotator. A movable wheelset can be installed under the bottom plate of the welding rotator base to form a movable structure.

The rolling capacity of the active welding rotator is 3 times its load capacity. In addition to one-master and one-slave pairing, it can also be paired with one-master and two-slave to meet the needs of longer workpieces. Strong rolling ability can adapt to the needs of highly effective eccentric workpieces. It adopts a DC servo motor to drive PWM speed regulation, or AC asynchronous motor to drive frequency conversion speed regulation, with a wide speed regulation range and stable rotation.

Equipped with an advanced controller, the starting, stopping and speed regulation of the welding rotator can be remotely operated on the hand control box. The welding speed can be preset and digitally displayed, and it can be connected with the manipulator system produced by our company to realize linkage operation.

Performance characteristics of welding rotator:

1. Welding rotator is divided into the adjustable type and self-adjusting type. The four rollers of the driving frame adopt full gear meshing transmission to realize four-wheel drive. One is the active welding rotator and the other is the driven welding rotator, which can be directly fixed on the workstation or installed on the track.

2. The welding rotator is generally used in groups, and the swing angle of the roller group is automatically adjusted according to the diameter of the workpiece, without manual adjustment.

3. When the imported frequency converter is used for stepless speed regulation, the adjustment range is wide, the starting torque is large, and the accuracy is high. There is a linkage interface in the electrical box, which can be connected to the operating machine control system produced by our company to achieve linkage operation

main feature:

1. The welding rotator is used in conjunction with the manipulator and submerged arc welding. It can complete the welding of the inner and outer longitudinal seams or the inner and outer circumferential seams of the workpiece. It is a piece of important auxiliary tooling equipment for the circumferential seam welding of large cylinders and the inner and outer arm welding. It can also be used for the Displacement of workpieces in manual welding, assembly, flaw detection, and other occasions.

Electric welding rotator operating procedures:

1. The operator must be familiar with the basic structure and performance of the machine, reasonably select the scope of application, master operation, and maintenance, and understand electrical safety knowledge.

2. When the cylinder is placed on the welding rotator, check whether the centerline of the supporting roller is parallel to the centerline of the cylinder to ensure that the supporting roller and the cylinder are evenly worn.

3. Adjust the focal length of the two groups of Torun centers to 60°±5° from the center of the cylinder. If the cylinder is too heavy, a protective device should be added to prevent the cylinder from being strung out when the cylinder is rotating.

4. The welding rotator must be adjusted when the machine is at a standstill.

5. When starting the motor, first close the two-pole switch in the control box, turn on the power, and then press the "forward" or "reverse" button according to the welding requirements. When you need to stop the rotation, you can press the "Stop" button. If you need to change the direction of rotation in the middle, you must first press the "stop" button to adjust the direction and turn on the power of the speed control box. The speed of the motor is controlled by the speed control knob in the control box.

6. When starting, adjust the speed control knob to the low-speed position to reduce the starting current, and then adjust the speed to the required speed according to the job requirements.

7. In each activity department. Lubricating oil must be filled in every shift, and the lubricating oil in each turbine box and bearing needs to be checked regularly; bearing lubricating oil is recommended to use ZG1-5 calcium-based lubricating grease, and adopt the method of frequent replacement.

Features of welding rotator reducer:

The linear speed of the welding rotator itself is relatively slow, and it must meet the following electromechanical requirements for the reducer of the transmission part

1: The output is a hollow shaft output with a round output flange. The hollow shaft output is to facilitate installation, and the round flange is to reduce the workpiece, which can reduce the diameter and cost of the roller.

2: The speed ratio of the reducer is large. Generally, it is composed of VF series worm gear reducer and a micro cycloid reducer. It is driven by a frequency converter to drive the motor, which can reach a speed range of 1 to 10 times.

3: 2T~600T adjustable machine-adjustable and adjustable welding rotator generally use a combined reducer of 0.18 kW to 2.2 kW, which is called a special reducer for welding rotator.

4: Low speed, low frequency, and large torque, this is the characteristic of welding rotator reducer, often many motors are running at low frequency and it is easy to burn out the motor. The motor requires special craftsmanship.

Structure of welding rotator

Description of special reducer for welding rotator:

This series of reducers are matched by VF series reducers and WB series miniature cycloid reducers, specially designed for welding rotator

1. Welding rotator equipment must require a large speed ratio and a large speed range. And our welding rotator special reducer VF+WB adopts a double-stage reducer, and the speed ratio can be achieved from 300-3000;

2. WB is equipped with ordinary motors, which can meet the requirements through frequency converters, and does not need to be equipped with frequency conversion motors, reducing customer costs;

3. The VF worm gear reducer has a circular shape, and the diameter of the wheel core is small, which will not interfere with the workpiece, reduce the diameter of the roller and reduce the cost.
