Description

Seamless butt joint wire take-up system and wire take-up method thereof
Technical Field
The invention belongs to the technical field of wire take-up devices of wire drawing machines, and particularly relates to a seamless butt joint wire take-up system and a wire take-up method thereof.
Background
The existing metal wire drawing process flow is that after a plurality of drawing processes, the metal wire is finally wound on a plastic disc to form a finished product.
When the metal wire after being drawn is wound on the plastic disc, the winding speed of the metal wire cannot be equal to the drawing speed of the preorder drawing production line. In the initial and final stages of the winding of the metal wire on the plastic disc, there is a stage of acceleration or a stage of deceleration of the winding speed.
And when the winding of one plastic disc is finished and the next empty disc is replaced, the winding speed of the metal wire is 0. While the metal wire in the preceding drawing line is still in drawing at a certain speed. If the plastic disc needs to be replaced, the pre-drawing process is stopped, the production efficiency is seriously influenced, and the resource waste is caused.
The traditional solution is: the metal wire is drawn to a final specification product, a large spool is used for winding and winding, and after one large spool is fully wound, another empty spool is replaced, so that the minimum downtime can be realized, and the yield can be improved; then the full large spool is turned to a coil separating layer for winding, the wire on the large spool is paid out by a pay-off machine, and then the wire passes through a tension mechanism and a straightener and is finally coiled into a small coil by a layer winding machine.
The above solution still presents a phase of machine halt, during which bad filaments or defective threads are produced. And change large-scale I-shaped wheel and need artifical the participation, increased intensity of labour, and the manual work produces misoperation easily. If the layer winding machine is directly connected with the drawing production line, the links of winding and unwinding of a large spool can be eliminated, and the manual participation is reduced. In order to overcome the contradiction between the take-up speed of the metal wire in the coil separating and take-up stage and the wire feeding speed of the metal wire in the drawing process, a seamless butt joint take-up system is needed to be developed, so that the seamless butt joint of the take-up is realized.

The drawing wire storage mechanism B stores the metal wire and is matched with the release speed of the metal wire in the subsequent process. And then the metal wire reaches the rear die box E through the upper steering guide wheel C and the lower steering guide wheel D. Because the metal wire is extruded or rubbed on the drawing wire storage mechanism B to influence the flatness of the circular section, the rear die box E plays a regular role.

1. the friction mode is removed to drive the differential ring, the motor is used to transmit power through the synchronous belt wheel, and the running speed can be improved through electric operation control. Because the friction mode is not suitable for high speed, the heating value is large, the abrasion of the friction belt is increased, and the service life is shortened.

One motor drives the timing pulley 16 and the other motor drives the timing pulley 17, thereby achieving power transmission.
2. The power of the wire storage reel is driven by the wire, and the wire storage reel is controlled by the pneumatic brake when the wire storage reel stops, so that the probability of wire disorder of the wire on the reel is reduced.
3. The rotating speed of the differential ring is half of the difference between the rotating speeds of the drawing winding drum and the wire storage winding drum, so that the differential ring is slow in rotating speed, less in heating value and stable in operation.
