Winding force sensor for hard metal wire, and winding force detection method

Abstract

The invention discloses a winding force sensor for a hard metal wire, and the winding force sensor comprises a wire-passing guide wheel, a cantilever pressure sensor, and wire-pressing guide wheels, wherein the wire-pressing guide wheels are divided into left and right groups, which are respectively installed on support platforms on left and right sides of the cantilever pressure sensor. The invention also discloses a winding force detection method of the winding force sensor for the hard metal wire, and the method firstly makes the hard metal wire sequentially pass through the wire-pressing guide wheel on the left side, the wire-passing guide wheel and the wire-pressing guide wheel on the right side, starts the winding machine to tension and wind the metal wire that will generate downwardpressure on the wire-passing guide wheel and the detection axis of the cantilever pressure sensor, obtains the relationship between the pressure and winding force by the trigonometric function operation, and calculates the winding force of the metal wire, so that the real-time monitoring of the winding force of the hard metal wire during the winding process is realized, and the installation is flexible and convenient, which is suitable for the upgrade and reconstruction of large cable production equipment.

Description

technical field [0001] The invention belongs to the field of winding force detection, in particular to a winding force sensor and a winding force detection method for hard metal wires. Background technique [0002] The hard metal wire is the inner core of the hard cable. In large-scale hard cable production equipment, in order to ensure the winding quality and specification consistency of the hard metal wire coil, the winding force of the winch when winding the metal wire is controlled. There are very high requirements, that is, the winch is required to always maintain a suitable size of winding force when winding the metal wire. If the winding force is too small, first, it may not be possible to straighten the hard metal wire, and there will be many bumps on the wire coil; second, because the hard metal wire passes through the transition guide wheels on the production equipment, the resistance is relatively large If the winding force is too small, the entire winding speed ...

Problems solved by technology

However, for hard metal wire production equipment, because the metal wire itself is hard and heavy, and the winding force of the winch is also large, the vibration of the metal wire is also large during winding, which will affect the detection accuracy; in addition, because the hard metal wire It is difficult to recover after deformation, so it is necessary to control the bending angle during the measurement process, so it is no longer suitable for soft wire and thin wire winding force sensor and measurement method

At present, for hard metal wires with a diameter of more than 5mm, such as single-strand copper core wires, there is no practical winding force sensor and winding force detection method. In the actual production process, the operator's experience can only be used to judge and control the winding force. The size of the winding force, so the degree of automation of the production equipment is low, and it is difficult to guarantee the quality and specification consistency of different batches of finished coils. It is necessary to provide a new type of winding force sensor and winding force detection method for hard metal wires to solve the above problems
