Description

Constant tension device of initiative unwrapping wire of cage stranding machine
Technical Field
The utility model relates to a permanent tension device of initiative unwrapping wire of cage stranding machine belongs to wire and cable and makes the field.
Background
In the wire and cable manufacturing industry, a cage stranding machine is an indispensable stranding device. When stranded, the constant and consistent tension of each core wire is critical to the electrical and physical properties of the stranded cable. At present, the tension control method mainly comprises the mechanical tension of a brake band, the permanent magnet tension and the magnetic hysteresis tension which are passive tensions and can not realize constant tension. In order to really achieve constant tension and consistent tension, a brand-new active paying-off constant tension device needs to be designed to ensure the quality of the cable.
Disclosure of Invention
The utility model discloses a permanent tension device of initiative unwrapping wire changes the method of acting as go-between passively before, but carries out the initiative unwrapping wire to the core through the unwrapping wire motor to realize that the permanent tension of single sinle silk is unanimous with the tension of every heart yearn. The purpose of the utility model is solved by the following technical scheme: the utility model provides a permanent tension device of initiative unwrapping wire of cage stranding machine, it includes main body frame, and this main body frame is cradle frame, its characterized in that the left side of this cradle frame is equipped with the drum that has the sinle silk with two thimble fixed being rich in the centre, is equipped with the driving motor who drives the drum usefulness below, be equipped with respectively on the driving motor right side cradle frame and move the guide pulley group, decide the guide pulley group, displacement sensor, hysteresis clutch, motor and switching-over sprocket frequently change, the spindle nose and the motor that frequently changes of hysteresis clutch are connected, displacement sensor's draw head with move the guide pulley group and be connected, the sprocket is equipped with to hysteresis clutch spindle nose to link together through chain and switching-over sprocket and move the guide pulley group.
Preferably, the method comprises the following steps: the tension corresponding to the hysteresis clutch is controlled by the tension of the core wires, and after the driving motor drives the rotary wire coil, the movable guide wheel set moves back and forth to drive the telescopic movement of the pull rod head of the displacement sensor, the displacement sensor is driven to input signals to an external PLC control system, and the speed of the driving motor is regulated and controlled by the PLC control system, so that the constant tension of a single core wire and the tension of each core wire are consistent.
The utility model discloses an improvement to prior art, it has rational in infrastructure, and use control is convenient, simple structure to reduce use cost, improve characteristics such as work efficiency.
Drawings

Fig. 2 is a schematic view of fig. 1 taken along direction a.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings: fig. 1-2 show, a permanent tension device of initiative unwrapping wire of cage stranding machine, it includes main body frame, this main body frame is cradle frame, its characterized in that the left side of this cradle frame is equipped with the fixed drum of having a cable core of being rich in the centre with two thimbles, is equipped with driving motor 1 that the drive drum was used below, be equipped with respectively on the cradle frame of driving motor 1 right side and move guide pulley group 2, decide guide pulley group 3, displacement sensor 4, hysteresis clutch 5, motor 6 and switching-over sprocket 7 frequently change, hysteresis clutch 5's spindle nose and motor 6 frequently change are connected, displacement sensor 4's draw bar head and move guide pulley group 2 and are connected, hysteresis clutch 5 is equipped with the sprocket to link together through chain and switching-over sprocket 7 and move guide pulley group 2.
As shown in the figure: the tension corresponding to the hysteresis clutch 5 is controlled by the tension of the wire cores, and after the driving motor 1 drives the rotary wire coil, the movable guide wheel set 2 is driven to move back and forth to drive the telescopic movement of the pull rod head of the displacement sensor 4, the displacement sensor is driven to input signals to an external PLC control system, and the PLC control system regulates and controls the speed of the driving motor 1, so that the constant tension of a single wire core is consistent with the tension of each wire core.
The active paying-off constant tension device designed by the invention solves the problem that the tension cannot be constant in the paying-off process, so that the quality of the manufactured cable is better than that of the common cable, the structure is very simple, and the efficiency of manufacturing the cable is greatly improved.
