GW300 forming machine
1.Brief introduction:
1.Usage:
GW300XG cold-bending forming machine is used to produce the light weight
steel keel, light weight steel joist and variety of industrial and ornamental
profiled bar. Making different shapes of profiled bar by changing different
shapes of mould.
2.Raw material:
(1)Cold-rolled steel strip(As per GB1591-88)
(2)Material of steel strip:low-carbon steel, low alloy steel.δs≤345Mpa,
δb≤610Mpa.
(3)The thickness of steel strip: 1.2~3.0mm(As per GB708-88)
(4)The width of steel strip: 100~300mm(±0.1mm)
(5)Steel coil: I.D. : ≥450mm
(6)Steel coil: O.D. : Ø1000~1300mm
(7)Steel coil: Maximum weight of steel strip: 1000~3000kg
3.The request of finished product:
(1)Width: 100~300mm
(2)Wall thickness: 1.2~3.0mm
(3)Length: 4~8M
4.Product process flow:
Raw material(steel strip)→Uncoiler→ Shearing and butt-welding→
Horizontal accumulator→Feeding and leveling→Forming→Mill→
Straightening→Fixed length cutting
5.Factory setting instructions:
(1)The factory site about: 40M x 4M
(2)5 ton bridge crane
(3)Total power: about 160KW
6.Milling speed: 20~60M/Min
2. Main components and technical parameters:
1.Uncoiler:
Structure type: single-side manual expanding tight, which insure steel
coil feeding alternatively and make steel strip go into accumulator freely.
Applicable range:
I.D. of steel strip: Φ500~Φ650mm
O.D. of steel strip: Φ1000~Φ1300mm
the width of steel strip: 100~300mm
weight of steel strip: 1000~3000kg
When the strip going to be finished,cut the two ends of strip and
welding together. So that the strip feeding could be continual.
2.Shearing and butt-welding machine:
Prepared by customer or outsourcing by seller.
Shearing and butt-welding machine, which insure two-coiled steel strips
shearing tidily and then welding together and leveling weld seam.
3. Strip leveling unit:
Combined by up and bottom rollers set(totally 4 up rollers, 5 bottom rollers).
Bottom rollers with drive and fixed, up rollers without drive but could be adjusted
in height by adjusting the guide screw to fit the strip tightly. To guarantee the strip
been leveled.
4. Milling unit:
Milling by the horizontal roll and vertical roll with different shapes of roller, to
Mill the steel strip into the final product needed. Guarantee the final product same
as the requests according to the buyers' blueprints. To making the product regular
and in the certain size. Our design is as below:
(1)Horizontal dragon gate shaped roller stand: 18 sets, diameter of roll's shaft is
φ70mm, material of roller stand as per QT iron, sealed boxed type, pulling from
Side(different way to change the roller to make the different product), the sliding
block of the dragon gate roller stand is processed by numerical control milling
machine, in high precision. The matching horizontal roller shaft is made by good
quality alloy structural steel 40Cr, the material has been hardened and tempered
to keep its shape with tenacity and hardness. The shaft is from the name brand
Chinese factory.(HA, WA, LUO factory)
(2)Horizontal roll could be adjusted up-down and left-right. To mill the strip into
the very shape.
(3)Vertical roll: 6 sets, the roll shaft diameter is φ40mm, to mill and guide the strip
with the horizontal roll. And make the product go into the next vertical roll
smoothly. Passively drive type. The vertical roll could be adjusted front-back and
up-down (by single screw), the sliding block is made by 45# inblock forge piece
and with strong hardness. The roller and the roll shaft are combined by shaft
bearing, and in high precision and could be sliding smoothly, avoid any scratch
on the surface of product. And the vertical roll system could have some special
setting to match the milling process.
(4)Straightening:
Turkey head type, one side 4 roll, used to do straightening of section bar. The unit
could rotate 360º, movable in the direction of up-down and front-back. To keep
the final product exactly matching the blueprints and go into the cutting moulds
smoothly.
(5)Main Drive:
The unit could perform the power transmission from the main motor and main
speed reducer to the distribution power box of forming unit and sizing unit. Then
transfer the power from the distribution power box to horizontal roll shaft.
(a)Main motor: Z4 series, 45KW DC one set
(b)Main speed reducer: ZLY224-outside 4 shaft ends one set
5. Hydraulic fixed length cutting unit:
(1)Cutting method: Hydraulic cutting
(2)Control method: mechanic-electronic-hydraulic integrated control
(3)Cutting length: 4~8m
(4)Cutting tolerance: ≤6mm
The operational principle is that after the milling and straightening, the cutting unit
will track the product, when the product automatically move to the very point
together with the on line car, signal sent out, then section bar cut, dropped into
collection table.
