III. Each Machine Parameters and Specifications:
(1) Uncoiler
|
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. | |||||||||||||||

Function:
It is used to parallel cut the tail of the steel strip, which has just gone into the accumulator, and the head of the strip coming out of uncoiler, and then weld them together.
Structure:
Hydraulic Shearing and manual welding Strip steel width: 39mm-160mm Strip steel thickness: 0.5-2.5mm Centering way: manual
(3) Spiral accumulator

(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) Cold saw
|
The cold saw used to precisely cut all kinds of frame tube automatically. Concerning to using high accurate STD control system and machinery system, this unit has the good precisely dimension advantage, and the machinery transfer best advantage, so the quickly ability and accurate processing,without Burr is this unit advantage. | |
