I. Summary and features:
1. Summary:
THCD-11 steel bowl welding machine is a kind of equipment used for ship welding and manufacturing, and a special welding equipment used for welding binding bowls of automobile ro-ro ships.
This equipment can meet the requirements of automatic welding of binding bowls with different diameters on automobile ro-ro ships. It is small in size, time-saving and labor-saving in moving and installing, and convenient to operate. The outside diameter of the binding bowl of the equipment is positioned, the switch magnet is adsorbed and installed, and the welding gun on the shipyard site is clamped to complete circumferential angle welding or flat butt joint. After the welding distance is set by the program, it will automatically stop, and the welding shape will be beautiful and consistent. The labor intensity of workers is greatly reduced, and the work efficiency can be increased by more than 3-4 times by one person with multiple machines.
2、Features:
⑴ This equipment can meet the requirements of circumferential welding of binding bowls with various diameters, and it is equipped with a swinging device to complete butt welding of cylindrical steel bowls.
⑵ The welding machine is small in size and light in weight, and can be operated by one person, which is suitable for the narrow space operation of the hull. It is adsorbed and installed on the top surface of the binding bowl by switching the magnetic attraction magnet, which saves time and labor in installation and movement.
⑶ The welding machine locates and installs binding bowls with different diameters by replacing positioning parts with different diameters, which has high positioning accuracy and simple operation, and reduces the requirements for operators.
⑷ The welding machine body rotates through gear transmission, which is stable and durable. The panel can be set to complete three different welding modes: 1/3, 1/2 and 1 turn.
⑸ The function button of the panel selects the diameter value of the steel bowl, and the panel will digitally display the actual welding speed during welding.
⑹ The welding machine is designed with the function of delayed start rotation. After the welding arc is stable, the rotating welding is performed, and the welding end position can be changed and set, so that the end-to-end joint of the weld is beautiful and full.
II. The applicable workpiece and shape:
1. HCD500-1P welding machine is suitable for the external circle welding of binding bowls of automobile ro-ro ships, which can realize the corner welding of conventional binding bowls and the external circle butt joint of embedded binding bowls. It can meet the requirements of binding bowl welding with diameter of 180mm-300mm and height of 40mm-50mm.
2. The workpiece should be made of magnetic conductive material. If there is no magnetic conductivity, the magnet of the welding machine can't be adsorbed on the workpiece, which will result in the unstable operation of the trolley and the welding can't be completed. The outside diameter of binding bowl of the same specification should be uniform to facilitate the positioning and installation of welding machine.
3. Applicable to common welding wires and flux-cored wires with φ Φ1.6mm and below.
