Spiral welding pipe unit LH-800 internal welding, external welding, rear bridge, fly cutting equipment.
1. Internal welding device
Function: Used to fix and adjust the inner welding head to ensure that the middle weld can be welded and submerged arc welding at the mesh of the forming joint.
Structure: Mainly composed of support, welding head moving slide and conductive wire rod.
Equipment description: The internal welding device is equipped with a torque motor, which can ensure that the welding head is correctly located at the weld, so as to obtain the key role of welding.
2. External welding device
Function: Used for fixed adjustment of the outer welding head to ensure that the welding wire is sent to the center of the weld, and submerged arc welding is carried out at the meshing of the forming joint.
Structure: Composed of column, beam, mobile device, etc.
Equipment description: The balance beam on the external welding device can effectively ensure the accurate finding of the welding spot, the beam can be driven by the motor screw up and down transmission; The welding head moving device is equipped with a gun head.
3. Front bridge
Function: Used to fix and bear the equipment before the molding machine, and can be rotated around the rotating shaft of the molding machine under the action of the oil cylinder, to produce different forming angles, to meet the production of different plate width and pipe diameter steel pipe.
Structure: Composed of bridge body, rotating lug, fine-tuning device, roller, etc.
4. Rear axle
Function: Used for fixing and bearing tube, pipe, fly cutting, external welding and other equipment, can swing ±1° around the forming machine under the action of the oil cylinder, eliminate the wrong edge, edge phenomenon in the process of steel pipe forming.
Structure: It is composed of bridge body, output bracket, output roller, measuring device, roller, fine-tuning device and deflection roller device.
Equipment description: The bridge body is shaped steel, and the steel plate is processed after welding. It is the carrier of all the equipment after forming. It has the function of fine tuning Angle and cutting pipe.
5. Helical welding pipe unit LH-800 flying cutting car
Function: It is used to cut the welded steel pipe into the finished pipe of fixed length according to the fixed length.
Structure: It is mainly composed of base, pneumatic system, car body, wheel jacking device and walking mechanism.
