Abstract
The utility model belongs to the technical field of metal rolling, which also relates to metal cold-bending forming. The utility model relates to a combined rolls for forming cold-bending sections, which comprises a roll shaft and a roll ring; the roll ring is composed of more than three roll sheets, and the shapes of the roll sheets are cylindrical, conical and of a circular polygon; the outer circle cutting line of the axial section of the roll sheet in the shape of a circular polygon can be any one of a straight line, a fold line, an oblique line or a curved line. The axial thickness of the roll sheets are 50 to 200MM, the radial thickness of the roll sheets are 5 to 100MM, and the outside diameters of the roll sheets are 100 to 500MM. Each roll sheet is provided with a shaft hole sheathed with the roll shaft.
Description
The utility model belongs to metal rolled roll field.Relate generally to the cold roll forming of metal.
Cold-rolled forming section has obtained application more and more widely as a kind of high performance steel, and the cold-rolled forming section description of using has more than 1000 at present, and the cold-rolled forming section of each specification all needs different roll shape.If adopt solid roll or whole roller shell, a difficult problem in the production process is exactly that roll spare part amount is big.
At present, the form that typical cold-rolled forming section roll mainly adopts whole roller or roll shaft to match with roller shell is as patent CN 2140273Y and CN 2107959U.The present situation that description at the cold-rolled forming section product is various, change in size is bigger, when producing with this roll tissue, the enormous amount of required roll, and utilization rate is low, causes production cost to rise.
The purpose of this utility model is to provide a kind of roller sheet storage capacity that reduces, and improves the composite (back-up) roll of the cold-forming shapes shaping usefulness of roller sheet utilization rate.
At above-mentioned purpose, the composite (back-up) roll of the utility model cold-forming shapes shaping usefulness, comprise roll shaft and collars, collars is combined by the roller sheet more than 3, being shaped as of roller sheet is cylindrical, in taper shape or the annulus polygon any, the cylindrical line of the axial cross section of annulus polygon roller sheet be in straight line, oblique line, broken line or the curve any.The axial width of roller sheet is 50-200mm, and the radial thickness of roller sheet is 5-100mm, and the external diameter of roller sheet is 100-500mm.
Each roller sheet all has and the roll shaft axis hole of suit mutually, and the diameter of axis hole is consistent with the diameter of roll shaft.
According to roll Pass design, each roller sheet that will match with pass is assembled on the roll shaft in order, and becomes the composite (back-up) roll of cold-forming shapes shaping usefulness described in the utility model.
According to the characteristic of each roller sheet, more various composite (back-up) roll system central roll sheet for property, the roller valut of setting up, when making the cold-rolled forming section of production plurality of specifications, the overall volume of the roller sheet of satisfying the demand and quantity minimum.
Compared with prior art, the utlity model has following advantage:
During the cold-rolled forming section of 1, production plurality of specifications, because shared roller sheet is more, the spare roll gross weight reduces, and single roller sheet is in light weight, is easy to transportation, is convenient to roll change.When producing five kinds of channel-section steels with composite (back-up) roll, the format roll of last rolling mill only needs seven kinds of roller sheets, if use whole roller, then is equivalent to the roll of 15 roller sheet weight.
2, single roller sheet appearance profile is simple, is easy to grinding.
3, diverse location can adopt the roller sheet of unlike material, when more renewing roller, can only change the heavier roller sheet of wearing and tearing, and the roller sheet of reduction consumes.
When 4, having avoided whole roller heat treatment, because corner's stress is concentrated the cracking that produces.
5, can adopt the roller sheet of unlike material to be combined into format roll.
6, the limited roller sheet of quantity available is combined into the format roll of multiple shape, realizes flexible roll, and a roller is used more.
7, composite (back-up) roll can be realized the trickle adjustment that whole roller can not be accomplished.
Now in conjunction with the accompanying drawings the utility model cold-forming shapes is shaped and is described further with composite (back-up) roll.
Accompanying drawing 1 is embodiment of the present utility model.
The structural representation of the composite (back-up) roll that accompanying drawing 1 is used for rolling special-shaped corrugated plating.
Accompanying drawing 2 is the structural representation of accompanying drawing 1 composite (back-up) roll central roll sheet 5,6,7,8,9,10 to accompanying drawing 7.
Find out that by accompanying drawing 1 composite (back-up) roll of the special-shaped corrugated plating shaping of embodiment usefulness is made up of roll shaft 3, axle key 4, roller sheet 5,6,7,8,9,10, locking plate 1, anti-bolt 2, interval roller shell 11, locking nut 12 and the broached bushing 13 opened. Roller sheet 5,6,7,8,9,10 is fixed on the roll shaft 3 by axle key 4, the effect that is axle key 4 is the relative slip that prevents roller sheet and roll shaft, roller shell 11 at interval is equipped with in the both sides of roller sheet group, determine the position of roller sheet group at roll shaft, after the position is determined, be the location by locking plate 1, locking nut 12 and the anti-bolt 2 of opening with whole roller again, and it is fixing, it is the axial location of locking plate 1, check bolt 2 and interval roller shell 11 stationary roll sheets, locking nut 12 closely links to each other with broached bushing 13, to prevent that the roller sheet is along the roll shaft axially-movable.
In above-mentioned roller sheet, the cylindrical line in the axial cross section of roller sheet, roller sheet 5 is a straight line, and roller sheet 6 is a broken line, and roller sheet 7 and 8 is a curve, and roller sheet 9 is an oblique line, roller sheet 10 is a straight line.
Adopt composite (back-up) roll described in the utility model to produce cold-rolled forming section, its roll spare part weight obviously reduces, table 1 has been listed employing the utility model composite (back-up) roll and has been produced channel-section steel, the roller sheet quantity that corrugated plating and angle steel are required and adopt whole roller to be equivalent to the quantity (comparing with weight) of roller sheet.Table 1 adopts the utility model composite (back-up) roll to produce the required roller sheet number of cold-rolled forming section and adopts the required suitable roller sheet number of solid roll (calculating by weight)
| The shaped steel kind | The required roller sheet of the utility model number (individual) | Adopt solid roll suitable roller sheet number (individual) |
| Channel-section steel (five kinds of specifications) | 7 | 15 |
| Corrugated plating (two kinds of specifications) | 13 | 18 |
| Angle steel (ten specifications) | 22 | 40 |
