Referring to fig. 1, after the steel wire branching is completed, the coiled steel wire is transferred to the surface treatment module 5, in this embodiment, the surface treatment module 5 includes a shot blasting machine, and the steel wire is shot-blasted in a shot blasting chamber of the shot blasting machine, so as to effectively improve the surface quality of the steel wire. Then the steel wire enters into the module of flare-outing 6, and the module of flare-outing 6's structural component is similar with cogging module 2, and the difference lies in the diameter of drawing die 825 that drawing die box 82 used in the module of flare-outing 6 is littleer, and the steel wire can obtain the finished product steel wire that diameter and intensity all accord with the requirement after the module of flare-outing 6.
The implementation principle of the cold-drawn steel wire production line in the embodiment of the application is as follows: the raw material steel wire is firstly derusted by a derusting module 1, and then is cogging by a cogging module 2, and the diameter of a wire drawing die 825 used in cogging is determined by the strength required by the final finished steel wire. In the steel wire cogging process, the traction action of the steel wire tension drum 83 firstly passes through the line folding mechanism 85, the line folding mechanism 85 comprises at least two line folding wheels 851, when the steel wire passes through the line folding wheels 851, the steel wire is attached to the periphery of the outline formed by the sequential connection of the connecting columns 853 due to the internal tension of the steel wire, and the connecting columns 853 which are distributed in a circular shape are sequentially connected to form a polygon shape, so that the steel wire can form wavy bending in the length direction after passing through the line folding wheels 851. The steel wire enters the wire drawing die box 82 through the preformed hole 824 after being bent to form a wave shape, the steel wire bent in the wave shape can pass through the preformed hole 824 due to the large aperture, the steel wire firstly passes through the wire drawing powder storage area 822 and then enters the scrap iron collecting area 823, and finally passes through the wire drawing die 825. The steel wire that the wave was buckled can drive more wire drawing powder behind wire drawing powder storage area 822 to make more wire drawing powder adhere to on the steel wire surface, thereby effectively improve the lubricated effect of wire drawing powder to the steel wire, can reduce the loss that the steel wire produced at drawing the in-process like this on the one hand, reduce the cracked possibility of steel wire simultaneously, on the other hand also can reduce wire drawing mould 825 and draw the loss that the in-process produced at the steel wire, thereby effectively prolong wire drawing mould 825's life.
The additive is added into the wire drawing powder, the additive is a mixture of magnesium stearate and barium stearate, the magnesium stearate and the barium stearate have good lubricating performance on the steel wire, but are not easy to attach to the surface of the steel wire, and the attachment capacity of the magnesium stearate and the barium stearate on the surface of the steel wire is indirectly increased through the arrangement of the folding line mechanism 85, so that the surface quality of the steel wire is effectively improved. By using the wire drawing powder with the formula, the step of phosphorus washing of the steel wire in the related technology can be omitted, and the pollution to the environment in the process of phosphorus washing of the steel wire is reduced.
Then the steel wire divides many simultaneously and anneals through annealing module 3, and many steel wires branch the line through branching module 4 after annealing is accomplished, are provided with steel wire branching device 7 in the branching module 4, and the steel wire is guided to hollow main shaft 72 through one-level direction fixed pulley 77, and then stretches out and is guided to walking hole 712 department through second grade direction fixed pulley 78 from the other end of hollow main shaft 72, and then is guided to bobbin 74 surface through third grade direction fixed pulley 79 again. The arrangement of the boss 713 provides a sufficient space for the routing of the steel wire, when the steel wire is tightly wound on the transition inclined plane 714, due to the inclined arrangement of the transition inclined plane 714, when the internal tension of the steel wire is high, the coil formed by the steel wire tends to be tightened, and therefore the steel wire tends to move in the direction of reducing the diameter on the transition inclined plane 714, once a subsequent steel wire applies a force in the axial direction of the transition inclined plane 714 to the steel wire tightly attached to the steel wire, the steel wire can easily move in the axial direction of the transition inclined plane 714, so that the steel wire is enabled to continuously move on the bobbin 74 in the direction far from the transition inclined plane 714, and the possibility that the steel wire is continuously accumulated and wound at the root of the bobbin 74 in the winding process is effectively reduced.
With the continuous feeding of the wire, the wire moves along the guide bar 751 to the position of the wire connecting cylinder 76, and when the wire reaches the end of the guide bar 751 close to the wire connecting cylinder 76, the wire is sleeved outside the wire connecting cylinder 76 along the guide bar 751, so that the wire is transferred from the wire winding cylinder 74 to the wire connecting cylinder 76. Compare with the current mode of directly taking off the steel wire from around the reel and transferring to a take-up reel 76, through adding steel wire guide structure in this application, with the steel wire section by section and steady transfer to take-up reel 76 department, and at the in-process that shifts, be difficult for taking place violent collision between the steel wire, effectively reduced the steel wire surface and received the possibility of damaging in the transfer process, improved the surface quality of final off-the-shelf steel wire.
And after the steel wire is subjected to wire splitting, the steel wire is subjected to surface treatment by the surface treatment module 5, so that the surface quality of the steel wire is further improved. In this embodiment, adopt the shot-blasting machine to throw the ball to the steel wire surface to reach the purpose that improves steel wire surface quality, compare with traditional pickling mode, environmental protection more.
