Description
Technical field
The present invention relates to a kind of material during tensile equipment, particularly relate to a kind of stretcher of electric wire metal wire rod.
Background technology
Wire drawing machine in electric wire production equipment is front road production equipment indispensable in electric wire production process, and the wire rod such as copper, the aluminium drawing-down elongation under the effect of certain pulling force as electric wire conductive core material is reached required wire diameter specification by it.The form of wire drawing machine has multiple, its conventional form realizes wire-drawing operation by pulling wheel, pulling wheel is arranged on wire drawing machine, pulling wheel is circumferentially provided with wire drawing guide groove, on each pulling wheel, corresponding wire drawing guide groove is arranged in same plane, to treat that the wire rod of Wire Drawing to be from first to last wound on each pulling wheel in corresponding wire drawing guide groove successively respectively, wire rod is equivalent to wire rod to be relatively fixed on pulling wheel after reeling on wire drawing guide groove, from first to last carry with the rotation of pulling wheel, wire rod reels and after being relatively fixed on pulling wheel on wire drawing guide groove, namely the speed discrepancy of adjacent two pulling wheels provides pulling force wire rod drawing-down extended, this part wire rod be wound in wire drawing guide groove rotates the effect that substantially can not be subject to pulling force with each pulling wheel, and just produce with the rotation of pulling wheel from the input of inlet wire side again from the dynamic transport motion that outgoing line side exports, this length of wire between adjacent two pulling wheels then can form the difference of linear velocity because of the speed discrepancy between two pulling wheels, the linear velocity of input side is less than the linear velocity exporting side, thus this section of wire rod will produce plastic deformation thus be extended by drawing-down, its diameter change accurately can be controlled by the die throat diameter of the wire drawing eye mould arranged between adjacent two pulling wheels, after multiple pulling wheel, treat that the wire rod of Wire Drawing progressively will be reached required size by drawing-down, such wire drawing mode and corresponding wire-drawing equipment are widely used.
Along with the progress of technology, the desired value of wire-drawing equipment speed of production and efficiency is being improved constantly, also more and more higher to the requirement of product quality, when adapting to such needs, the wire rod that above-mentioned wire-drawing equipment is produced often occurs that there is the phenomenon of damage on surface, cause the difference of product quality, sometimes also there will be the mutual line ball of the wire rod be wound in wire drawing guide groove overlapping, the extreme case of broken string is even had to occur, and on inspection these phenomenons generation with input treat that the wire quality of wire drawing there is no direct correlation, these are all to the output of wire-drawing equipment, efficiency and wire drawing quality cause larger impact.The analysis carried out for above-mentioned phenomenon shows, treat that the wire rod of wire drawing is wound on each pulling wheel in corresponding wire drawing guide groove successively respectively, the number of turns that on same pulling wheel, input side wire rod and the axial location residing for outlet side wire rod and gauge or diameter of wire and wire rod reel in wire drawing guide groove is relevant, and be arranged in the same plane axially vertical with pulling wheel due to wire drawing guide groove corresponding on each pulling wheel, make like this wire rod actual motion between adjacent two pulling wheels path direction can with the axial out of plumb of pulling wheel, there is certain misalignment angle, gauge or diameter of wire is larger, the number of turns that wire rod reels in wire drawing guide groove is more, so the misalignment angle that produces of the path direction of wire rod actual motion and the axial out of plumb of pulling wheel is also larger.The theoretical path run between adjacent two pulling wheels in wire rod drawing process we be referred to as the wire drawing path of wire rod, wire rod is in the process stretched, owing to being subject to enough large pulling force, its theoretic wire drawing path is always with pulling wheel axis perpendicular, if the Actual path of wire rod has deflection, in drawing process, the actual motion path of wire rod just naturally can to wire drawing path convergence, namely can be tending towards axially vertical with pulling wheel, that is on same pulling wheel, the axial location of the wire rod of input side or outlet side all can the close trend of the axial location of oriented the other side, this just causes wire rod has mutual extruding in wire drawing guide groove, this extruding mutually can cause the friction of wire rod when entering or leave wire drawing guide groove with pulling wheel rotation and between the adjacent wire rod be wound in wire drawing guide groove, the existence of this friction obviously can cause the damage of wire surface, this damage can affect product quality on the one hand, injury region stress may be caused on the other hand in follow-up continuous drawing process to concentrate, damage defect is amplified gradually, until produce fracture, the existence of this friction also can make enhanced stretch resistance become large, increases stretching power attenuation and causes the waste of power, the wire rod of surface damage also can cause extra wearing and tearing to pulling wheel, wire drawing die etc., increases the loss of machine material and standby redundancy, reduces production efficiency, increases production cost.In addition, on same pulling wheel, the wire rod axial location of input side or outlet side even also can produce line ball to the trend that the axial location of the other side is close when serious, namely the overlap of wire rod in reeling, this can cause wire rod to be directly pulled off in running, produces larger loss.
