Abstract
The utility model discloses a steel wire tension control unit. The steel wire tension control unit comprises a supporting frame, a storage device arranged on the supporting frame in rotating mode and used to store steel wires, a drive motor used to drive the storage device to rotate, a fixed pulley connected with the supporting frame in rotating mode, a movable pulley arranged relative to the supporting frame in rotating and sliding mode, a metal block fixedly arranged on the movable pulley and an inductive switch arranged on the supporting frame. The inductive switch is in electrical connection with the drive motor. In the process of cutting the steel wires, due to the fact that the steel wires wound on the movable pulley and the fixed pulley are elongated, the movable pulley slides upwards relative to the supporting frame, when the movable pulley approaches the inductive switch, the inductive switch controls the drive motor to work and then rotates the storage device, the steel wires on the storage device are fed, at the moment, the movable pulley slides downwards and returns to an original position under the effect of gravity of the metal block, and the operation is repeated. In the process, the steel wires are in tension states always, tension of the steel wires are controlled effectively and accuracy of cutting size is high.
Description
Technical field
The utility model relates to a kind of steel wire tension control setup.
Background technology
In the pulling rope for automobiles manufacturing, steel wire is generally lopping and becomes circle, in the process of processing and manufacturing, needs steel wire is blocked, and when blocking, usually driving the steel wire memory device by a drive motor rotates, steel wire carried block, in this process, the tension force of steel wire can not get favourable control, so that by intercept unit with steel wire block the time, cause the cutoff size inaccuracy, so that the product quality of making reduction, and can cause raw-material waste.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of steel wire tension control setup is provided, and controls at full tilt the tension force of steel wire, so that when blocking, precision is higher.
For achieving the above object, the technical solution of the utility model has provided a kind of steel wire tension control setup, comprise bracing frame, rotation is arranged at the memory device that is used for the storage steel wire on the described bracing frame, drive the drive motor that described memory device rotates, only also comprise the fixed pulley that rotates and be connected with described bracing frame, the movable pulley that rotates with described bracing frame and can slide mutually and arrange along above-below direction, be fixedly installed on the derby on the described movable pulley, be arranged at the inductive switch on the described bracing frame, described movable pulley is positioned at the below of described fixed pulley, and described inductive switch is electrically connected mutually with described drive motor.
As preferably, be fixedly installed the slide bar that length direction extends along above-below direction on the described bracing frame, rotate on the described movable pulley and be provided with sliding part, described sliding part is sheathed on the described slide bar slidably.
As preferably, the length direction of described slide bar is perpendicular with the rotary centerline of described movable pulley, described fixed pulley respectively.
As preferably, the rotary centerline of described movable pulley, described fixed pulley, described memory device is parallel to each other.
As preferably, described derby is bound by rope mutually with described movable pulley.
As preferably, described inductive switch is between described fixed pulley and described movable pulley.
As preferably, the diameter of described fixed pulley is greater than the diameter of described movable pulley.
As preferably, offer respectively a plurality of draw-in grooves for walking around for steel wire on described fixed pulley and the described movable pulley.
Advantage of the present utility model and beneficial effect are: carry out steel wire when blocking, because the steel wire that is wound on movable pulley and the fixed pulley is elongated, so that the relative bracing frame upward sliding of movable pulley, when movable pulley during near inductive switch, the work of inductive switch control drive motor, then rotate memory device, so that the steel wire on the memory device is filled, movable pulley glided under the derby action of gravitation and resetted this moment, so repeat, in this process, steel wire remains tensioning state, its tension force is effectively controlled, so that the cutoff size precision is higher.
Description of drawings
