Description

Wire storage type non-stop drawing winding drum and operation method thereof
Technical Field
The invention belongs to the technical field of winding drums of wire drawing machines, and particularly relates to a wire storage type drawing winding drum without stopping and an operation 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.
Therefore, there is a need to overcome the contradiction between the take-up speed of the metal wire in the take-up stage and the wire feeding speed of the metal wire in the drawing process, and it is necessary to develop a winding drum, so that when the take-up speed of the metal wire in the take-up stage is less than the wire feeding speed of the metal wire in the drawing process, the metal wire can be stored in the winding drum, thereby avoiding the shutdown of the previous drawing process.
