2.5 Size of the whole line: Approx. 80X6m
2.6 Direction of input material: buyer supply finally
Uncoil → Cutting head tail → Strip Steel head-tail welding → Spiral accumulator(buyer supply)
→ Forming → High frequency induction welding → Removing external burr → Sizing →zinc painting(buyer supply)→ Cutting→ end facer →Stack→Checking& collecting → Accessing Warehouse
This equipment has double cone clamping . The end opener has press roller,. The uncoiler cones head clamp the steel coil with the function of cone. Then press roller of the end opener moves down to tighten steel coil. The uncoiler cone rotating, the ends opener peeler swings up and close to the coil. When steel coil head rotate to the peeler,
Inner diameter of the strip steel:Φ 508mm (the buyer supply finally)
Outer diameter of the strip steel:Φ max=2000mm
Strip steel width: 70mm-200mm
Strip steel thickness: 0.8-4mm
The maximum weight of the strip steel: 4.0T
Hydraulic expansion
Pneumatic break
2.Straight head and pinch leveling machine
This unit is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place.
straight head motor power :AC1.5KW
processing pressure:7Mpa
The leveling unit with 2 roll pinch and 5 roll leveling.
pinch roll diameter:Ф140mm
leveling roll diameter:Ф110mm
pinch and leveling motor:15kw
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: 70mm-200mm
Strip steel thickness: 0.8-4mm

Feeding Set
Mainly to upper and lower limit of strip steel, easy for strip out of the loop smoothly into the forming machine, prevent strip bobbing up and down.
Consists of a pair of roller and left and right bracket, the roll material is Gr15, high frequency quenching process.Quenching hardness HRC58-62, the left and right bracket is the steel plate welding structure
Mainly to level off the steel strip ,for strip into the machine smoothly, prevent strip bobbing up and down
Using upper 2 lower 3 five roller type structure, the above two roller can adjust alone, respectively to control the clearance of the upper and lower roller, ensure leveling effect, leveling roll material is Gr15, high-frequency quenching, quenching hardness HRC58-62
Horizontal roller frame is the key components of the forming and sizing mill,by the strip into the pipe billet and the guarantee of the size precision of steel tube is done by it
Horizontal roller stand with gantry structure, side out roll change
Under of the lower roller of horizontal roller has overload protection pad, when overload to reduce the damage of horizontal roller and bearing
Protect the cushion material is HT200
Horizontal roll axis increase roller fixed end trimming nut, is advantageous for the production of thin material adjustment
Horizontal roller end cover material from the original HT200, instead of Q235A, in order to prevent in the later use process, the breakage of the end cover.On the end cover seal uses oil seal.In order to prevent the scale and iron into the bearing, increase the service life of bearing, all connecting bolts from the original ordinary level to 8.8 high strength bolt, to ensure that in the future the connection strength and stability in the process of long-term use.
Frame and link table USES four 8.8 high strength bolt, ensure the rack in the later production process stability and accuracy
Vertical roll stand is the key components of the forming and sizing mill, main help horizontal roller deformation, prevent strip rebound, absorb part of the edge of the waiting stretching
Vertical roll stand adopts single screw adjusting operation, on the roll change
Vertical roll materials adopts the cast steel, with the tension plate device on the vertical roller, vertical roller with upper and lower adjusting nut,the height could be "tuned", In order to adjust production thin material like climbing a hill
Weld Seam Guide Stand is mainly control the size of the opening corner and the direction of the
weld, the weld accurately into the extruding roller, to ensure the welding quality, guide roller frame can be plus or minus 20 degrees along the pipe axis rotation, adjust up and down, and around.
Shaft diameter φ55(gear model# 7511)
Squeeze Roll Stand is mainly to the high frequency heating pipe billet extrusion into welded pipe, is a major part of the guarantee welding quality, extruding roller frame structure is the same with vertical roll
Conditioning treatment after rough turning, and then finish turning, after finishe turning high frequency quenching treatment, grinding after high frequency quenching
It 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.
It is used to chill weld area for ensuring steel pipe be straighten precisely. It adopts the structure type that combines sprinkling and water bath into one.
Sizing machine
Another name is Turks head and stated at the last part of sizing mill, it is used to straight strip pipe coarsely. It is made up of two sets of four- roller straightening and head can revolve and adjust for right and left. It utilizes three-point way to straight steel pipe.
It is used to connect gearbox and horizontal roll stand, it also connect main gearbox and
extension gearbox. It adopts tailor-made transmission shaft. It is advantageous for using, maintain, changing and matching, also it owns overload safeguard function for horizontal stand.
Unit reducer adopts secondary screw arc gear reducer. Each reducer consists of a pair of spiral arc gear and two on cylindrical gear. The advantage of speed reduction gear box is sturdy and durable, low cost of maintenance and replacement. bevel gear material: 20CrMnTi
6.Cold Saw (kaikong)
|
It is used to precisely cut the pipe to length automatically under the condition that the pipe continuously delivered from the mill at high speed.
|
|
It is used to carry pipe after cutting by cold saw. Structure and work principle: It is made up of bench and drive electric machine. The pipe is carried to blanking place by round roller and then will start collecting.
