III. Each Machine Parameters and Specifications: (1) Double cone Uncoiler | The uncoiler is of the structure of double expansion and cantilever
mandrels. It contains two main parts: main body and the fixed base.
The main body is equipped with manual system to satisfy the needs
of expanding, contracting and braking of the mandrels . | OD of coil | φ1800mm | | ID of coil | Φ508mm | | Width of strip | 80-240mm | | Thickness of strip | 1.0-3.0mm | | Weight of strip | Max3.0T | | Expansion Type | manual | | Break | Pneumatic driving |
|
(2) Automatic shear and welder | The shear welder is a important unit to the pipe mill line
equipment, and main used to cut the no-normal strip steel head or
trial, and then connecting the last strip steel trial with the next
strip head so as to ensure the processing continue. | | Strip width | 80-240mm | | Welding thickness | 1.0-3.0mm | | Cutting Type | hydraulic | | Welding Mode | Automatic | | Pneumatic pressure | 0.5MPa | | Working Cycle | Max.300 seconds |
|
| - This machine is used between the shearing welding machine and the
mainframe (forming sizing machine). Its function is to run out of
the previous strip, and the next strip is prepared from The
continuous production of the main machine (forming sizing machine)
is ensured within a time and sufficient strip steel is stored.
- This machine is mainly composed of feeding guide roller frame,
clamp feeding device, looper body assembly, discharging device and
electrical control device.
- feeding device: mainly composed of a frame, a motor, a brake, a
universal drive shaft of a reducer, a pinch roller, and a guide
roller pneumatic system. It can feed the steel belt into the
looper. When the feeding needs to stop, the brake It can stop the
motor and the clamp feeding roller from rotating, and the electric
motor's rotation speed and feeding speed can be adjusted by the
electric control device.
- Looper body assembly: It is mainly composed of motor, machine base,
inner circumferential roller, center discharge roller, outer ring
roller and pressure roller, etc. It can store the strip steel sent
by the clip feeding device and can be from the center The discharge
roller is withdrawn.
- Discharging device: It consists of a bracket, a guide roller group,
an upper and lower lead-out roller, and a speed measuring device.
It can horizontally introduce the steel belt stored in the looper
body into the forming unit and make the device.

| | PART 2. Weld seam guide and the squeeze roll stand,welding bead cutter | squeezing roller is to squeeze the edge of the tube which has been
heated to welding temperature, by squeezing rolls giving a certain
pressure to achieve welding purpose. Welding bead cutter is used to scrap weld seam and remove external
burr. It is made up of two cutters for using alternately. If one is
damaged, the other one will take the place to scrap. Scrapers can
be adjusted and have the quick lift function by cam. There are two
supporting roller underneath knife rest, in order to bear the
overdraft of scraping.and after the bead cutter with one horizontal
stand for polishing. | | Scrap knife | 2 sets | | Squeezing roll stand structure | 5 roll squeeze | | squeeze roll shaft diameter | 50mm | | squeeze roll shaft diameter | 40Cr |
