Technical Field

The invention relates to wire drawing production and manufacturing equipment, in particular to wire coiling machine wire coiling loading and unloading automatic equipment and a wire guiding processing method thereof.

Background

The wire drawing machine is a device for driving wires to overcome the resistance of a die to reduce the diameter of the wires. After the diameter of the wire becomes the desired diameter, the wire needs to be wound up in cooperation with a take-up spool, and a wire coil is generally installed on the take-up spool and then taken up.

The wire inside the wire or cable is also reduced in diameter by a wire drawing machine during production, and then wound up by a wire reel to be transferred to the next process.

At present, when the wire coiling of the wire coil is completed and is in a full coil, the lead wire is manually cut off and the wire tail on the full coil is fixed, and then the full coil is manually dismounted and placed at a specified position. After the lead is cut off, the free end of the lead is formed, the empty disc to be wound is installed and fixed on the winding shaft, and then the lead end of the lead is fixed on the empty disc, so that winding of the lead can be started. The installation of the empty tray is also performed manually, and although the installation of the empty tray is automated, the automatic operation cannot be performed yet as to how the wire ends of the leads are led to and fixed on the empty tray. The metal wire is different from the common silk thread, and after being wound on the wire coil, the full coil has large weight, and the wire coil is manually unloaded, so that the labor intensity is high, the wire cannot be automatically produced, and the production progress is greatly influenced. In the process of switching between the full tray and the empty tray, the automatic wire unloading tray cannot be realized, the wire cannot be automatically processed, and the waste of the wire data is also greatly caused.
