Be coordinate the copper cash annealing out can match in speed with take-up 7 and admission machine oneself store when moving disk and pull out
Line.
3 groups of double-roll rolling mills 2 are cores of the present utility model plus the combination of 7 die wire drawing machine 3, and copper bar is by 3 groups of double-roll rolling mills 2
Totally 6 secondary roll rolling, then draws by 7 die wire drawing machines 3 again, can make the copper cash of 10mm diameters by the mode of cold-rolling deformation
Make copper wire diameter drastically diminish, produce required specification.
In 3 groups of double-roll rolling mills 2, the linear velocity per pair roll is all different, and its linear velocity is calculated is：After 7 die wire drawing machines 3
The linear velocity of constant speed wheel 4 be fixed, the linear velocity of the 6th mould is that the linear velocity of constant speed wheel 4 draws divided by the lengthening coefficient of the 6th mould
, linear velocity during wire drawing machine inlet wire, that is, the 3rd group of linear velocity of the vertical roll stacks of milling train can be calculated by that analogy,
It it is K times of horizontal roll group according to the linear velocity of vertical roll stacks, K is to be processed the extension that copper cash is rolled by vertical roll stacks
Coefficient, then, the linear velocity of the 3rd group of horizontal roll group of milling train is also vertical roll stacks linear velocity prolonging divided by horizontal roll group
Stretch what coefficient drew, the linear velocity of every secondary roll can be calculated by that analogy, so as to calculate the rotating speed of every secondary roll, see figure
5。
During processing, copper bar enters in tandem-rolling continuous machine drawing of the present utility model by putting lever apparatus 1 and releasing, and the 1st group is rolled
Machine horizontal roll group makes copper bar section become ovalisation, then its section is rolled into circle again by vertical roll stacks, so by 3
The copper cash that section diminishes after individual milling train enters 7 die wire drawing machines, sequentially passes through 7 stretchings of mould, obtains required copper cash specification.
But copper cash at this moment is hard, is annealed by annealing device 5, obtains soft copper cash and be received on drum.So entirely produced
Journey is just completed.
The utility model is machined with two remarkable results for copper cash：
1st, the copper cash lattice structure for processing is uniformly fine and closely woven, advantageously reduces defect and continues to reprocess；
2nd, the copper cash energy consumption of production unit weight is significantly reduced.
