Description
Technical field
The utility model relates to roll manufacturing technology field more particularly to a kind of welded tubes and cold-rolled forming section assembly roller.
Background technique
There is more than 2700 item of welded pipe product line in China at present, it has also become the big Welded tube production of the first in the world and country of consumption, about generation
The 1/2 of boundary's total output.The consumption of Welded Pipe Roller is also very big.Cold-rolled forming section is to use rolling for longitudinal arrangement under normal temperature conditions
The strip of rolling one fixed width.The output of steel of China's clod wash type have developed rapidly, and the whole nation shares 1000 a plurality of cold-rolled forming section productions
Line, kind is up to more than 3000.
Roll is the prerequisite for restricting steel rolling technology development level, and welded tube and cold-formed steel roll belong to the industry " four
The key foundation components of one of base ".Welded tube and cold-formed steel roll service condition are severe, and cold and hard pipe leans on roll rotation
Frictional force drive and advance, while generating thermal stress because of severe friction.The failure mode of roll is rolled mostly based on abrasion
The working face of roller is easy to appear fatigue crack and peeling phenomenon.It is therefore desirable to which roll has heat crack resistance, working face can be born
The very repeated stock on large contacting stress and receiving pipe head and tail portion, and require roll that there is good intensity, toughness
And wearability.The chilling and shock heating of high temperature and cooling water acts on when Welded Pipe Roller is because will also be welded；The work of roll is required simultaneously
Enough thickness will be had to meet the requirement of abrasion post-processing reparation by making layer.
Welded tube and cold-formed steel roll belong to non-cylindrical variable diameters abnormal shape roll, and majority is that both ends diameter is big, intermediate straight
The small bent cylindricality of diameter, centre has a through-hole so as to installation axle.Welded tube and cold-formed steel roll specification kind are various, but same specification product
Kind batch is few, and most drawings only make 1~2, big more than ten tons every reachable, the small substance every of polishing roll substance
Less than 10 kilograms.Therefore, cause that the manufacture difficulty of roll is big, energy consumption is high, stock utilization is low.Using the roll of forging molding
Can be forged into cylindrical body, be subsequently processed into type, stock utilization is less than 50%, and machining period is more, increases cost.Using
Casting and forming is again since the small part of roll mid diameter easily first solidifies, to cause lower part feeding insufficient.Especially substance is big
Workpiece, easily generation shrinkage cavity or loose to causing to scrap, or expose casting flaw in use and influence steel pipe
Surface quality.
Utility model content
The problem of the utility model is for welded tube and cold-formed steel roll existing manufacturing technology and deficiency, propose
One kind carried out from structure it is improved, can saving metal material and energy simultaneously can be improved roll quality welded tube and cold-rolled forming section combination roll
Roller.
The distinguishing feature of technical solutions of the utility model is, roll is decomposed into jacket and inner sleeve two parts, housing is
The working portion of roll, using wrought tool steel or the high ferrochrome material of casting, inner sleeve is the coupling part of housing, using high quality carbon
Plain structural steel or alloy structure steel material.Wherein, the housing is decomposed into from pass center edge perpendicular to inner hole direction equal part
Two components, i.e. the first housing 1 and the second housing 2, the inner sleeve are made of inner sleeve 3 and activity stopper 4, and the inner sleeve 3 is installed
In the inner hole of first housing 1 and the second housing 2, by being mounted on the activity stopper 4 of 3 other end of inner sleeve, by institute
It states the first housing 1 and the second housing 2 is fixed together, form the assembly roller of the utility model.
The first housing 1 and the second housing 2 of roll described in the utility model are the small song of the big other end diameter of one end diameter
Cylindricality, first housing 1 and the second housing 2 connect at the small bent cylindricality decomposition of diameter, and it is complete to form the utility model
The small roll hole shape of the big mid diameter of both ends diameter.
The inner sleeve 3 of roll described in the utility model is made of hollow shaft and fixed stopper, and one end of hollow shaft is connected with vertical
Directly in the fixation stopper of hollow shaft, the outer circle of fixed stopper and diameter of a circle outside 2 end of first housing 1 and the second housing are big
It is small identical, and be strip along center line symmetrical setting；Outside the outer circle of the activity stopper 4 and first housing 1 and second
The diameter for covering 2 end outer circles is identical, and is strip along center line symmetrical setting；First housing of roll 1 and second
Design has the long striped groove along center line symmetrical setting on the end face of housing 2, for installing the fixation stopper and activity of inner sleeve 3
Stopper 4.
When the inner sleeve and housing two parts of roll described in the utility model combine installation, to all faying faces of the roll
Equal matel coated glue is adhesively fixed, and activity stopper 4 and inner sleeve 3 is welded and fixed, and after assembling, carries out finished size
5 processing.
The technical solution of the utility model has following two aspects remarkable advantage, i.e., complex-shaped workpiece is decomposed forming shape
The big workpiece of weight is converted into the small workpiece of weight and combined, to reduce manufacture difficulty, realized by simple workpiece combination
The newly net forming of blank, reaching ensures quality, energy-saving material-saving and the good result for reducing cost.
