Working Flow：

 

Coil loading → uncoiling → shovel head → pinching&leveling → shearing and butt-welding→ accumulating → Feeding → Guiding → forming → HF welding → deburring → Weld seam polishing → water cooling → sizing and straightening → cut to length → run out table → automatic stacking and packing.

 

 

Main feature ：

 

The line is driven and controlled by control panels and electrical cabinets with built-in PLC controller, electric motors; has a hydraulic system with hydraulic stations, pneumatic equipment, as well as emulsion supply units and works as a single technological complex.

Forming, sizing and straightening of material in an automatic pipe production line is carried out using roller equipment.

2.Main machine technical parameter and feature:

- There are 4 forming stands in the 1st profiling area, it is a single stand with two rollers, and both sides are deformed simultaneously. The roller is moving when the product specification is changed, and it is not necessary to change the rollers.

-There are 5 forming stands in the 2nd profiling area. The forming technology is the same as the 1st profiling area, both sides deforming at the same time. When tube specification is changed, it is not necessary to change the roller.

- The closed profiling area forming area and the squeeze rollers, do not need to change the rollers when the tube specification changes.

- Sizing and Straightening stand no need to change rollers when tube size changes.

 

3. Automatic stacking and packing machine

Function: Collecting run out tubes automatically and packing automatically.

Structure: Consist of tube fetching device, chained conveying mechanism, aligning device and stacking device.

 

Steel package requirements:

- Raw material specification: Square/Rectangular 40-100mm
