HG 160X160X8 Automatic pipe line

General Introduction:



This machine is our company in order to meet the requirements of the international market, according to our company LW series unit combined with FF forming technology,developped the automatic square and rectangular tube mill line.

The cold-formed multi-point pre-bending process is adopted to make the deformation soft, the deformation stress is not concentrated, and the strength of the steel pipe is improved. The molding process adopts a combined mold design, and a set of molds can produce rectangular steel pipes of any specification within the specified range. The rolls are completely shared, the rolls can be saved by 90%, the roll change time can be reduced by 90%, and the production capacity can be increased by 80%, which can meet the production mode of multiple varieties and small batches.




,The main characteristics of the equipment:

In a very short period of time to finish the adjustment of the roller, extreme reduce the roller change time when replace the products, thus improve the efficiency and reduce the productive cost;


  • Due to the equipment adopts one set of combined mould, producing the different specifications of the tube, only need to adjust,no need to change,the roller savings rate at above 90%,thus reducing the cost of the roller;
  • Due to the equipment adopts the motor automatic adjustment,thus decreasing the number of workers,reduce the labor costs,decreased the workers labor intensity, improved the workers working environment;
  • The equipment operation is simple,just need to know the size and the wall thickness of the tubes in the production,then input it to the interface,it will make adjustment automatically, thus lower levels of debugging personnel's technical requirements;
  • With automatic adjustment, decreased the input of tools and damage to equipment when change the roll, improve the service life of the equipment;
  • Due to structure of the composite roll,the point contact between the roll and strip instead of the original line contact,reduce the roll wear and improve the service life of roll;

Can produce a certain specification of opening cold bend steel, such as U,C section steel etc., width and height of the product can be adjusted infinitely.
