Blade edge:2
3: Vertical accumulator
Vertical accumulator: sheet go through from the vertical
Coil width:40~130mm
Coil thickness:1.2~2.0mm
Feeding speed: 100~160m/min
Structural style: Turn direction stand, pinch devic), main body of accumlator
Steel coil feed and discharge control: feed with manual control, share the same console with uncoilor, discharge is powerless.
4:: Forming and Sizing machine 4.1 Feeding device
Vertical guide roller: a pair of vertical guide roller after flatten roller, adjust open and close by hand
Flatten roller: With 7 rollers to make coil enter into forming machine steadily, flatten rollers are motorless, with down rollers fixed and up rollers adusted by first screw
4.2 Forming stand
Machine adopts bottom line horizontal roller forming theory, with double
radius holes style
Forming requirements:
Out diameter:φ14~φ40mm;
Wall thickness:1.2~2.0mm;
4.3 Forming stand specifications: Roller stand Quantity Shaft diameter Roller material Shaft heat treatment Horizontal 7φ60mm 40Cr HF quenching Vertical 8φ40mm 40CrHF quenching 4.4 Forming stand structural requirements:
There is a vertical roller group stand before the back three-path flatten roller stand, avoid the pipe surface scratching.
Above each opening forming horizontal stand, the top of bearing, there
is a overload protection device. The cushion have buffer when overloading, to protect horizontal roller and transmission device,no need to change new cushion
Horizontal roller is gantry structure, including
Open forming: 4 stands Close forming: 3 stands
Vertical roller is chute structure, including
Doublevertical guide rollers, adjust open and closed same time by hand With vertical roller up-down adjustable structural
Ways of changing roller: side pull
Stand lubrication: at the back of horizontal rollers stand, use oil gun with lubricating nipple
5: Welding equipment (mechanical part)
Welding seam guide stand: (1set)guide roller including up and down 2
rollers, in the middle have guide blade, welding seam angel adjust by screw.
Welding squeezing roller stand: (1set) three rollers (up roller is
disassemble), squeezing rollers squeeze melt metal and weld together
A: make sure the cutting position of specifiedlength, start fast to made synchronous between cutting equipment and production line. B: Keep synchronous between cutting equipment and production line,cut pipes by means of cutting structure move C: Fast resetting: Control method: motor controlled by micro-computer through reduction boxgearing rack and pinion drive flying cutting
Cutting method: friction metal cut saw
Max speed of flying cutting off:60m/min
Cutting diameter:φ14~φ40mm
Cutting wall thickness:≤2.0mm
Cutting accuracy:±3mm
Cutting specifiedlength:6m
Saw blade rotation speed:3400rpm
Cutting motor:7.5KW
Tracking motor:11KW
Pneumatic system:0.4~0.7Mpa
8,Back roller stand
Holding stand structural form:structure steel welding
Roller stand height mark: same with pipe rolling and the center of flying cutting off discharge table
Holding roller form and material: holding rollers are plain-barrel ones, material: steel 45#quenching hard chrome-plated with long working life and without scratching pipe.
Power of roller: use 3kw motor drive which can satisfy different production speed.
Reverse direction: (pipe forwarding direction)
9: Drive system
The whole system adopts combination transmitting between forming machine and sizing machine, main motor of each system through reducer box,gear box(spiral bevel gear) and universal shaft to drag horizontal roller. Vertical rollers are powerless. spiral bevel gear material is 20CrMnTi
Water pipe distribution: machine prepares the total entrance for cooling water,each roller installs adjustable metal cooling pipe spray head,flux of cooling water: ≥10 ton/hour
