3) 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 roll type structure, the above two roller can adjust by motor turbine worm reducer alone respectively,to control the clearance of the upper and lower roller, ensure leveling effect.leveling roller material GCr15,high frequency quenching process.

Leveling range 100-400mm

Leveling thickness:1.5-4.0mm

Turbine worm reducer Two sets

4) Horizontal roll rack

Little edge real curved

In accordance with the requirements of synchronous free bending forming,the basic requirement of small edge forming has three points:

Side cannot be longer due to the bending tensile and waved and affect the welding production;

After the small edge turn into empty bend ,to guarantee in the empty turn R accurate shape;

Small edge always does not affect the bend Angle on the side of the big boundary when the final bending Angle of bent.

Structure: the little edge real curved divide 3 ways.Due to the above edge real bending length is shorter, 3 ways all adopt the horizontal roll.Bilateral deformation at the same time.From the first to third ways are upper and lower roll initiative.Three horizontal roller frame on each time has a three independent adjustment of roll, respectively installed on the upper and lower two horizontal axles, in the production of different specifications of the square and rectangular tube, two of the cantilever rack has the different position relative to the centerline of rolling, so need two cantilever rack opening and closing at the same time , adjust the frame of the opening and closing, respectively by two sets of frequency conversion motor with high precision turbine reducer drive screw rotation, screw and frame joint nut connection, so as to ensure that opening and closing adjustment, to ensure that the unit rolling centerline is changeless,two cantilever rack can around at the same time.Opening and closing ajustment,the upper roller can be individually do axial adjustment.

Big edge bending

structure:

The side real curved divide three ways.

Forming method the same as small edge,as bilateral deformation of frame structure at the same time, the same as the small edge forming frame;

5) Vertical roll rack

The first is in the transition between the two horizontal roller frame deformation;The second is to overcome the front one horizontal roll deformation after springback, and play a guiding role.Change specifications roll around on the rack to move, don't need to replace the roll, the discretion of the vertical roll adjustment by the electric device to drive the turbine worm up and down, the main purpose of the adjustment is, in the different specifications of the square tube and rectangular tube small edge is different, in order to make the vertical roll better positioning effect, high and low adjusting greatly solved this problem.

6) Three frame Empty curving rack

Empty curving rack is a diameter of 16 roll deformation rack, four roller under the horizontal position unchanged, upper roller has a  frequency conversion motor drive, upper roll two roller can adjust Angle separately.Vertical roll powered by a  frequency conversion motor, meet different pipe diameter in the case of silent empty curving effect is better,to guarantee weld constant extrusion welding position, not reverse.

Equipped with guide plate at the exit to the empty curving rack,to make the extruding roller opening a corner.

7) Guide roller frame

Guide roller frame 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

8) Five roll extruding device

For five roller, two side roller can according to separate adjustment of the welding conditions.Upper depress roller has two pieces, besides can electric lift adjustment at the same time,also can manually adjust alone, in order to adapt to different welding conditions, two roller can also carry on overall lateral movement, when the center of the weld seam deviation,can do adjustment laterally through horizontal roll to meet the welding requirement.

9) Scraping welding frame

Scraping welding frame is mainly to extruding roll extrusion welding the weld by scraper, the leveling of the welding, scraping welding frame with two drag frame.Only a handful of at ordinary times, the other a spare, to ensure the production line smoothly welding head can up and down, left and right sides, rapid tool adjustment to ensure good welding quality, scraping welding frame adopts steel plate welding structure, welding head to the dovetail structure, material for cast steel, the reserved zinc spray device.

10) Tumbling frame

Main usage is to support steel pipe, reduce vibration, improve the quality of welding and cutting, and roller pressing on not completely cooling cutting surface, improve the quality of products.Structure for two roller,lower roller height unchanged,upper roller as manual lifting adjustment, according to the different specifications of products, the upper roller pressure adjustment to the appropriate value, to achieve the above purpose.

11) Cooling system

Cooling system was mainly will be fully cooled down after the welding of steel pipe, in preparation for the sizing, in order to prevent the finished product after cooling pipe deformation, mainly steel plate welded structure,above the liquid spray directly on the seam, again by the recycling pool recycle.

12) Four roll rack

Four roller rack is made of upˎdownˎleft and right of four horizontal roll crossing.The up and down roll with the power, respectively with two motor with reducer as power.The lower roller as fixed roller, the left side of the roller and the upward side of the lower side roller forming 90 ° vertical angle. Through four roll cross action, with engine base lateral translation, so as to realize the size changed of the square tubes, rectangular tubes
