High Frequency Welded Steel Pipe Making Machine Cnc 12mm MS Tube Mill Machine

• Uncoiler

The uncoiler is of the structure of double expansion and cantilever mandrels.The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.
 

• Automatic shear and welder

Used to cut off the irregular part of the tape head and tail, and align the tape tail of the previous coil with the tape head of the next coil, and weld them together to continuously feed the looper.
Structural form: shear welding bed, pinch feeding device, double centering device, double shearing shearing system, shearing plate system, welding bottom plate driving system, etc.
 

• Vertical accumulator

This machine is between shear welder and host (forming sizing mill) ,use for after a roll of strip steel are used up, before the next roll strip since prepared from uncoiling, shearing and butt welding time to ensure that the host (forming sizing mill) continuous production and store enough strip steel.
 
specification:

• Forming →Sizing

Unit layout :
1)Forming part:
This part is used to squeeze the steel strip into a specific shape, leaving a gap for welding.
 
2)250KW High frequency welder (Stainless steel special):
 
HF welder is designed for straight seam induction welding of pipe and for continuous working. The whole set of equipment achieve the function of equipment linkage control and diagnosing faults by PLC system, the working statue is observed by LCD display.
3)Polishing part:
This part is used for polishing welds, and is often used for thin pipes that are not suitable for scratching.
 

1. 
   Annealing:

The annealing part adopts a closed environment and is filled with nitrogen to prevent the tube from oxidizing and discoloring during the annealing process.
5)Sizing part:

Finish product to proper shape and straighten.
