Equipment Main Structure and Performance

 

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

 

Five roll Passive leveler machine

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 roll stand

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

 

Diameter of Horizontal Roll Shaft is Ф80mm(gear model:back #3516,former #32216); material is 42CrMo; high frequency quenching.

 

Adjust up and down method: manual .

 

 

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

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

 

 

Diameter of Roll Shaft is Ф50mm, material is 40Cr, high frequency quenching.

 

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

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

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

 

Squeeze Roll Shaft Dia. is Ф60mm(gear model #7512); material is 40Cr; high frequency quenching.

Conditioning treatment after rough turning, and then finish turning, after finishe turning high frequency quenching treatment, grinding after high frequency quenching

 

Remove external burr Device

 

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.

 

Water cooling

 

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

 

Rough Straightening Device(turkey head)

 

 

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.

 

Cardan Axle Assembly

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.

Reduction gearbox

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.

Drive motor 15KW servo motor (Japan Yaskawa);
