Operating Instructions and Precautions for Welding Roller Carrier

As a welding auxiliary device, the welding roller carrier is often used for the rotary work of various cylindrical and conical weldments. It can cooperate with the welding positioner to realize the internal and external circumferential seam welding of workpieces. In the face of the continuous development of welding equipment, the welding roller carrier is also constantly improving, but no matter how it is improved, the operating procedures of the welding roller carrier are basically the same.

Inspection before use of welding roller carrier
1. Check whether the external environment meets the requirements and there is no interference from foreign matters;
2. No abnormal noise, vibration and smell during power on and air operation;
3. Check whether the bolts at each mechanical connection are loose. If they are loose, tighten them before use;
4. Check whether there are sundries on the guide rail of the coupling machine and whether the hydraulic system operates normally;
5. Check whether the roller rotates normally.

Operating Instructions for Welding Roller Carrier
1. The operator must be familiar with the basic structure and performance of the welding roller carrier, reasonably select the scope of application, master the operation and maintenance, and understand the electrical safety knowledge.
2. When the cylinder is placed on the roller carrier, check whether the center line of the supporting wheel is parallel to the center line of the cylinder to ensure that the supporting wheel and the cylinder are in uniform contact and wear.
3. Adjust the center focal length of the two groups of supporting rollers to 60 °± 5 ° with the center of the cylinder. If the cylinder is heavy, protective devices shall be added to prevent the cylinder from escaping when it rotates.
4. If it is necessary to adjust the welding roller carrier, it must be carried out when the roller carrier is stationary.
5. When starting the motor, first close the two pole switch in the control box, turn on the power, and then press the “forward rotation” or “reverse rotation” button according to the welding requirements. To stop the rotation, press the “Stop” button. If the rotation direction needs to be changed midway, the direction can be adjusted by pressing the “Stop” button, and the power supply of the speed control box is turned on. 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 it to the required speed according to the operation requirements.
7. Each shift must be filled with lubricating oil, and the lubricating oil in each turbine box and bearing shall be checked regularly; ZG1-5 calcium base grease shall be used as bearing lubricating oil, and the method of regular replacement shall be adopted.

Precautions for use of welding roller carrier
1. After the workpiece is hoisted on the roller frame, first observe whether the position is appropriate, whether the workpiece is close to the roller, and whether there is any foreign matter on the workpiece that hinders the rotation. After confirming that everything is normal, the operation can be started formally;
2. Turn on the power switch, start the roller rotation, and adjust the roller rotation speed to the required speed;
3. When it is necessary to change the rotation direction of the workpiece, press the reverse button after the motor stops completely;
4. Before welding, idle the cylinder for one circle, and determine whether the cylinder position needs to be adjusted according to its displacement distance;
5. During the welding operation, the ground wire of the welding machine cannot be directly connected to the roller carrier to avoid damage to the bearing;
6. The outer surface of the rubber wheel must not contact with fire sources and corrosive substances;
7. The oil level in the hydraulic oil tank shall be checked regularly for the assembling roller carrier, and the sliding surface of the track shall be lubricated and free of foreign matters.
