As an important tool to improve welding efficiency and ensure welding quality, the rotating welding table is being incorporated into the production system of more and more manufacturers. This article will discuss in depth how to improve welding productivity through the rotary welding table from the aspects of equipment principle, functional advantages, application scenarios, etc.
What is a rotating welding table?
The rotary positioner is an important equipment to assist welding work. By rotating and positioning the workpiece, the robot can obtain the ideal processing position and working speed. The positioner can be customized according to different uses and needs, including different parameters such as rotation axis, positioning accuracy, and moving speed. It can be used with manual welding, automatic welding or robot welding systems to achieve 360° positioning and continuous welding of the weld.
The basic structure usually includes:
- Table/chuck: used to clamp the workpiece;
- Rotary motor: drives the worktable to rotate stably;
- Frequency conversion speed regulation system: the rotation speed can be adjusted according to the welding speed requirements;
- Control system: realizes forward and reverse, inching, linkage and other controls;
- Optional functions: such as tilt function, foot switch, PLC interface, linkage with robot, etc.
How does the rotating welding table improve productivity?
1. Workpiece positioning and transfer
The rotary positioner can quickly and accurately reach the desired position through its precise control system, thereby realizing an efficient production process.
2. Improve the flexibility and diversity of the production line
The positioner can adapt to different production requirements through its flexible operation mode, realize rapid switching and adjustment of the production line, and improve the diversity and flexibility of the production line.
3. Realize automated production
By cooperating with other automated equipment, the positioner can realize automatic control of the entire production process, thereby reducing manual intervention and improving production efficiency. This is especially important for enterprises engaged in mass production and continuous production, which can reduce costs and improve product quality.
4. Improve production efficiency and reduce energy consumption
The rotary positioner can achieve high-speed operation of the production line through its efficient motion control system, thereby improving production efficiency. At the same time, due to its precise positioning ability, it reduces waste and errors in production, reduces unnecessary resource consumption, and helps enterprises achieve sustainable development.
Wide application scenarios
1. Pipeline/flange manufacturing industry
Butt welding and girth welding in pipeline welding are highly dependent on rotational motion. The rotating welding table can be used for automatic rotation positioning of workpieces such as long pipes, elbows, and flanges.
2. Pressure vessel manufacturing
Products such as gas storage tanks, boilers, and reactors often involve large-diameter welds. The rotary welding table can cooperate with the automatic welding head to complete the docking of the head and the cylinder.
3. Welding of automotive parts
Circular parts such as drive shafts, brake drums, wheels, suspension structures, etc. often require a rotary welding table to improve speed and consistency during welding.
4. Metal furniture/mechanical structural parts
In the welding of circular bases, gear wheels, and cylindrical components, the rotating turntable structure makes the welding of complex parts simple and efficient.
How to judge the quality of the rotating welding table?
1. Check the flip drive
- The tilting drive should be stable, without shaking under load, and the whole machine should not overturn. If the load exceeds 25kg, it should have a power drive function.
- A limit device should be provided to control the tilt angle, and there should be an angle indication mark.
- The tilting mechanism should have a self-locking function and not slide under load.
2. Check the rotary drive motor
- The rotary drive motor should achieve stepless speed regulation and can achieve braking.
- Within the rotation speed range, the speed fluctuation should not exceed 5% when under load.
3. Other aspects
- The welding positioner is equipped with a conductive device to prevent the welding current from passing through the transmission parts such as bearings and gears. The resistance of the conductive device should not exceed 1mΩ, and its capacity should meet the requirements of the rated welding current.
- The control part of the welding positioner should be equipped with a linkage interface for automatic welding.
- The structure of the workbench should be convenient for installing the fixture and determine its structural form.
- The instruction manual of the welding positioner clearly states the exact data of load, eccentricity and weight distance.
Summary
In the current context of intelligent manufacturing, the rotating welding table has become a key tool for the manufacturing industry to improve the welding process level with its high efficiency, precision and safety. It not only improves welding speed and consistency, but also reduces manual dependence. It is one of the indispensable equipment in the process of transformation to welding automation.
