Description
Technical Field
The invention relates to an automatic ending device for the tail end of a seamless metal sheath cable, which is used for stably taking out the tail end of the metal sheath cable from a drawing, reducing and rounding die.
Background
With the rapid development of the communication industry, the cable is updated rapidly, and the updating of the cable with the outer sheath having the conductive function is particularly prominent. The outer protective layer is also developed from a conductive material to a seam welding metal sheath, and from the seam welding metal sheath to a seamless metal sheath, and the series of improvements lead to the innovative rapid development of equipment, a production process and a manufacturing method. Due to the high-speed development of production equipment, development of some corresponding matched tooling dies is delayed.
In the rolling production of the seamless metal sheath cable, the seamless metal sheath rolls and rolls a large-diameter metal pipe by dozens of rollers to reduce the diameter, and the advancing of the seamless metal sheath is to advance the reducing by the rolling and rolling of the rollers to complete the reducing of the metal pipe so as to ensure that the metal pipe is in good contact with a cable core. In order to ensure that the seamless metal sheath pipe is in closer contact with the cable core and the seamless metal sheath is smooth in roundness and surface, a drawing and rounding die is required to be arranged behind the last roller. Because the tail end of the seamless metal sheath cable loses forward power after passing through the last roller, the drawing reducing rounding die has the reducing function and can pass through by needing large pulling force or pushing force, and a small distance is reserved between the last roller and the drawing reducing rounding die, so that the tail end of the seamless metal sheath cable cannot pass through the drawing reducing rounding die, and continuous production cannot be realized. When each cable is produced to the tail end, the passed seamless metal sheath cable needs to be cut off from the back of the drawing, diameter-reducing and circle-correcting die, the tail end of the remaining seamless metal sheath cable and the drawing, diameter-reducing and circle-correcting die are detached from the die carrier together, and the tail end of the seamless metal sheath cable is withdrawn from the drawing, diameter-reducing and circle-correcting die through a mechanical method. And then, the drawing, reducing and rounding die is replaced on the drawing, reducing and rounding die frame. Because the tail end of the seamless metal sheath cable is taken out by a mechanical method, the damage to a drawing, reducing and rounding die is large, and the service cycle of the die is short.
In order to solve the technical problem, the existing solution is to forcibly draw by using the tension of a take-up reel, firstly relax the tension, then quickly retract, and draw the tail end of the seamless metal sheath cable through a drawing reducing and rounding die by using the tension inertia. Because the tension of the take-up reel is adopted for forced drawing, the surface part of the metal sheath cable which is taken up on the reel is damaged and the wire is occasionally pressed. And the tension of the take-up reel is adopted for forced drawing, when the tail end of the seamless metal sheath cable completely passes through the drawing reducing rounding die, the drawing reducing resistance disappears after the reducing is finished, and the seamless metal sheath cable can rapidly leave from the rolling mill under the action of high-tension take-up of the take-up device. Because the seamless metal sheath cable is just rolled and is not subjected to stress relief treatment, the elasticity is very strong, the tail end of the cable is quickly separated from a rolling mill, potential safety hazards exist, and people are easily injured.
