1. Firstly, place the winding wheel of the welded pipe manufacturing material on the feeding device and fix it; After fixation, the starting end of the material on the winding wheel is pulled out and passed through the workpiece positioning mechanism.
2. Pull the material transmitted by the workpiece positioning mechanism into the storage device, fix the starting end of the material in the storage device with a winding device, and the winding device winds and stores the material in the storage device.
3. Extract the material from the storage device and guide it into the forming device, placing it between two rows of side wheels. Start the forming device, and make the flat material into a welded pipe to form a preliminary product.
4. Introduce the finished welded pipe from the forming device into the high-frequency welding device, where the welders weld the gaps in the finished welded pipe to make it seamless, thus forming an intermediate finished product.
5. Introduce the intermediate finished product of the welded pipe into the cooling device for cooling. After cooling is completed, introduce the cooled intermediate finished product of the welded pipe into the sizing device for inner diameter straightening to form the finished product.
6. The finished welded pipe is introduced into the winding device through the welded pipe support mechanism and then through the wire arrangement device. At the same time, the winding device and wire arrangement device are activated to wind the finished product onto the winding device.
The beneficial effects of a welded pipe production line are
1. The welded pipe production line and its production method can limit the entry of materials into the fixed frame by setting up upper and lower rollers on the inner front side of the fixed frame, and three first movable pipes on the inner rear side, preventing the materials from swinging left and right during the movement and feeding process. The rollers and first movable pipes can rotate under the external force of the materials, thereby limiting the materials and preventing the materials from moving and wearing.
2. In the production line and method of welded pipes, the limit ring can support and limit the welded pipe products that enter the winding device from the sizing device. It can prevent the welded pipe products from shaking left and right during the winding process, and can also prevent the parabolic sagging and shaking of previous welded pipe products during the winding process, which can easily cause surface cracking of the welded pipe products. In addition, the inner lower end of the limit ring is equipped with a circular rod, which can rotate when subjected to external force.
3. The welded pipe production line and its production method limit the winding of welded pipe products on the winding device through a horizontal drum and two longitudinal second movable pipes. At the same time, the cylinder can drive the upper components to move back and forth, so that the welded pipe products can be evenly and stably wound on the winding device and evenly arranged on the winding device.
4. Welding pipe production line and production method: By setting up a dedicated feeding device, the winding equipment of welding pipe materials can be fixed to prevent slipping of the winding equipment and material scratches on workers, ensuring smooth feeding work.
