Wire tension controller of multi-strand spring digital control lathe

Abstract

The invention discloses a wire tension controller of a multi-strand spring digital control lathe, comprising a shell, a tension control assembly and a tension collection assembly. The tension control assembly comprises a magnetic powder brake and a damping part; the tension collection assembly comprises a cutting fiber wheel and a pressure sensor; the signal output end of the pressure sensor and the magnetic powder brake are respectively connected with an automatic control system of the lathe; and wires are led out from a wire box arranged in the shell to wind a circular cutting fiber groove before being led out of the shell by the cutting fiber wheel. The wire tension controller of the multi-strand spring digital control lathe automatically controls the tension of the wires in the production process, monitors and controls the tension of each strand of wires in a multi-strand spring processing process by the tension collection assembly and a data acquisition and control system, realizes the constant tension of each strand of wires and the uniform and constant tension among various strands of wires, monitors the tension in real time by an application program of an upper computer and fully realizes a self-tuning system of the tension so as to ensure the quality of a finished product of a multi-strand spring.

Description

technical field [0001] The invention relates to a multi-strand coil spring CNC machine tool part, in particular to a multi-strand spring CNC machine tool steel wire tension controller. Background technique [0002] The multi-strand coil spring is a coil spring made of several strands of steel wire wound into a steel cable. Since the steel wire used in the multi-strand coil spring is thinner than the steel wire used in the single-strand coil spring with the same function, the material strength is high. At the same time, the multi-strand coil spring During deformation, the mutual friction caused by the contact pressure between the steel wires can absorb energy and have a buffering effect, and the stiffness of each steel wire of the multi-strand coil spring is smaller than that of the single-strand coil spring with the same function. Under the action of dynamic load The life span is greatly improved. Its service life is 3 to 5 times that of the traditional single-strand coil s...

Problems solved by technology

In the prior art, the steel wire tension control design process is not perfect during the production process, resulting in unrecoverable plastic deformation of the steel wire being elongated or flattened, which often makes the produced springs scrapped in large quantities, which cannot meet the actual application requirements, and seriously Affect the quality and service life of the finished multi-strand coil spring, causing huge reputation and economic losses to the producer and user
