The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises workpiece 4, back kink 3, milling train body 2, preceding kink 1; Comprise roll 21 and rolling-mill housing 22 in the milling train body 2, preceding kink 1 comprises a fixedly bend wheel 11; The section of described roll 21 is reducing sections, and does fixedly to rotatablely move around axle 23; Described rolling-mill housing 22 is fixed; Described back kink 3 comprises that also makes the forward and backward mobile feed mechanism 31 of workpiece, preceding kink 1 also comprises movable bend wheel 12 11 that link to each other with fixing bend wheel, that can make progress or move down; When workpiece 4 is return, described before kink 1 make fixing bend wheel 11 do the motion of original direction by a movable bend wheel 12 that links to each other with fixing bend wheel 11, and movable bend wheel 12 moves up; When workpiece 4 advanced, described movable bend wheel 12 moved down;
The reducing section of described roll 21 is made up of the curve sealing; Consider the reason of processing, described closed curve can be made up of the eccentric arc of a plurality of different radiis; Described closed curve is to take all factors into consideration gained by the mechanical property of the working modulus of workpiece and material deformation.
Described back kink 3 also comprises depress roller 33, changed course roller 32;
The distance that described movable bend wheel 12 moves up is identical with the distance that workpiece 4 is return;
The described movable bend wheel 12 that moves up is connected with hydraulic cylinder 13 or weight;
Roll section configuration of the present utility model and existing roll section configuration are different, and existing roll section configuration is circular, and roll section configuration of the present utility model is many curves section, its objective is:
Consider the cold pressure processing characteristics, the yieldlimit of rolled piece and total working modulus ε
∑Mostly being power function curve changes.General total working modulus at 30% following σ s with ε
∑Increase and increase sharply, press rolled piece material σ s and ε
∑Variation relation reasonably selects rolling district curve can make the distribution of draught pressure be controlled at optimum range;
Also must consider the nip angle of rolled piece when considering draught pressure, after drafts was determined during existing mill milling, nip angle just determined, guarantee that rolled piece can be nipped naturally just must make nip angle when rolling less than angle of friction, otherwise rolling can not foundation; The utility model is owing to be big working modulus, and by existing milling method, nip angle can't satisfy, so the rolling district of roll crown curve is by the bite condition design, and nip angle changes with contact arc in rolling district;
As seen from Figure 2: rolled piece is by behind the rolling district 211 of reducing roll, rolled piece has become a variable cross-section body by a uiform section body, in order to obtain equiform new uiform section body, Ding Hou district 210 and Disengagement zone 212 except being arranged, rolling district 211 must be arranged also on many curves of roll section; The function in Ding Hou district is the uiform section body that precise thickness is arranged after making rolled piece rolling, and the Ding Hou district has enough length in design, guarantees that rolled piece can repeatedly pass through, to improve the thickness deviation of rolled piece; The function of Disengagement zone then is to allow rolled piece can break away from roll, and the certain stroke of energy rollback under the pulling of feed mechanism allows rolled piece begin the rolling of next circulation, thereby obtains the same new uiform section body of continuous shape; In other words the motion of rolled piece is a step motion in the operation of rolling of the present utility model.
The operation of rolling of the present utility model and existing reciprocating rolling mill are different, and common reciprocating rolling mill is that working roll is swung back and forth at specific curved section, and rolling-mill housing moves back and forth, and rolled piece travels forward; And rolling mill roll of the present utility model is only made unidirectional rotary motion, and frame maintains static, but rolled piece must move back and forth, and the realization of this process is cooperated by preceding kink and back kink to be finished.
Preceding kink can be made up of movable bend wheel and hydraulic cylinder, also can be made up of movable bend wheel and weight, and function is the advance and retreat of workpiece between balance and compensation milling train and the coiling machine.Because rolled piece moves forward all the time in the operation of rolling, in other words coiling machine is to batch forward all the time when rolling, in order not influence the operate as normal that retreats and interfere milling train of rolled piece, preceding kink is finished balance and compensate function by upper and lower the moving of movable bend wheel.
The milling train body is made up of motor, decelerator, double helical tooth wheel seat, universal catcher, rolling-mill housing, reducing roll, screwdown gear etc., and function is the rolled piece that shuts out given size.
Back kink is made up of depress roller 33, changed course roller 32, feed mechanism 31 and feed control device etc., function be the forward and back of rolled piece between balance and compensation milling train and the preceding kink and drag rolled piece after move, finish rolled piece by the variable cross-section body, to the process of new uiform section body and the moulding of back kink.
As shown in Figure 2, reducing roll section is formed three districts by several sections curves: rolling district 211, Ding Hou district 210, Disengagement zone 212.
Rolling district by little extremely big, considers material yield limit σ s and total working modulus ε in this district's sweep
∑Relation, this curve is made up of several sections different curves, is controlled at optimum range with distribution, metal flow and the nip angle that guarantees draught pressure, this curved section of different materials has different curve combinations.As seen from Figure 3: it is variable cross-section body 213 that rolled piece forms one by this back, district.
The Ding Hou district, identical at this district's arc radius, and be the zone of reducing roller section radius maximum, the arc length in this district has enough length in the design, guarantees that rolled piece can repeatedly pass through, to improve the thickness and precision of rolled piece.Rolled piece forms required uiform section body 214 (see figure 3)s by this back, district.
The Disengagement zone, be the zone of reducing roll section radius minimum, this district will allow rolled piece can break away from roll in design, and can satisfy the time requirement of the certain stroke of rollback, allow rolled piece begin the rolling of next circulation, thereby obtain the same new uiform section body of continuous shape.
As seen from Figure 3: the rolled piece that the reducing roll shuts out, the cross section is made up of variable cross-section body and uiform section body, in order to obtain the same uiform section body of continuous shape, rolled piece must retreat certain stroke makes rolled piece produce new uiform section body in next one circulation rolling, so circulates and finishes the whole operation of rolling.
