III. Each Machine Parameters and Specifications:
Double expansion and cantilever mandrels
1. double expansion and cantilever mandrels.
2. Contains two main parts: main body and the fixed base.
3. Equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.
4. Mandrel consists of four-bar linkages that could move radially at the same time.
5.The four-bar linkages in two groups are fitted on two shafts respectively. Powered by air cylinder, they expand and contract radially.
(2)Automatic Shear And Welder
Automatis shear and welder
It is used to cut the irregular ends of the strips and then connect the strips by welding. So it can let the line runing without stop when the before coil finish
(4)Forming And Sizing Machine
|Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.|
(5) Computor cutting saw
Cutting Saw machine is used to precisely cut the pipe to length automatically under the condition that the pipe continuously delivered from the mill at high speed.
|Diameter of pipe||
|Fixed Cutting length||4~12m|
|Saw blade cutting motor||AC15kW|
|Carriage driving motor||DC22kW|
(6)Run out table
1.The finished pipes run along the Roll Table and to be automatically moved onto the Bench. Then simple Packing Machine packs the pipes in hexagon shape.
2.The simple packing machine contains container and pneumatically driven alignment equipment.
3. Motor of Roll Bench: 3KW
4. Two direction down load pipe
5. With frequency converter to control running speed.
