Abstract
The invention relates to a constant tension paying-off device, which carries out automatic adjustment by means of a spring, a damping chain and a damping wheel according to the tension of a steel wire so as to lead the tension of the steel wire to be constant. The lower end of a lever fulcrum is provided with an adjustable pull spring; one end of the damping chain is connected in the middle of a lever; two line-passing wheels are arranged at the position of an elbow above the lever; and the position of the lever fulcrum is in rotary-pair connection with a machine body. The steel wire pays off from a horizontal H-shaped wheel, respectively passes through the two line-passing wheels at the position of the elbow above the lever to a stranding mechanism. When the tension of the steel wire is slightly loose in the paying-off process, a tension spring at the lower end of the lever is retracted, the upper end of the lever drives one end of the damping chain to deviate rightward in a slight rightward manner, so as to increase the friction between the damping chain and the damping wheel, thus increasing the tension of the steel wire; and when the tension of the steel wire is slightly tight in the paying-off process, the upper end of the lever drives one end of the damping chain to deviate leftward in a slight leftward manner, so as to reduce the friction between the damping chain and the damping wheel, thus reducing the tension of the steel wire. The mechanism adjusts the tension of the steel wire automatically, so as to maintain the tension of the steel wire to be constant in the paying-off process.
Description
Affiliated technical field
The present invention relates to the permanent tension stringing device of a kind of twisting frame, to guarantee the one-tenth thigh quality and the intensity of steel wire.
Background technology
Twisting frame is that many steel wires are twisted with the fingers into one, and every steel wire must keep the tension force of constant unanimity during unwrapping wire, and the quality that could guarantee to twist with the fingers into the line thigh is to improve the surface quality and the performance of line thigh.
Summary of the invention
The constant tension unanimity of every steel wire when twisting frame must guarantee unwrapping wire in the course of the work.The present invention adopts the tension force of steel wire in the leverage control unwrapping wire process, and the spring of lever lower end is regulated the frictional force between damping chain and the damping wheel automatically according to the tension force size of steel wire, keeps steel wire tension force in the unwrapping wire process to reach constant.
The technical solution adopted for the present invention to solve the technical problems is: an adjustable extension spring is adorned in the lower end of balance pivot, and damping chain one end is connected in the middle of the lever, and two wire-crossing wheels are equipped with in elbow, lever top, and lever becomes revolute pair to be connected at the fulcrum place with body.Behind oneself " I-beam wheel " unwrapping wire of steel wire, pass through behind two wire-crossing wheels of elbow above the lever to the mechanism of pooling capital respectively.Occur steel wire tension when pine partially in the unwrapping wire process, the extension spring of lever lower end is shunk, and the lever upper end drives damping chain one end to the right and is offset to the right, strengthens the frictional force of damping chain and damping wheel, thus the tension force of increasing steel wire; Steel wire tension occurs when tight slightly in the unwrapping wire process, the lever upper end drives damping chain one end left and is offset left, reduces the frictional force of damping chain and damping wheel, thereby reduces the tension force of steel wire.Mechanism regulates the tension force of steel wire automatically, makes steel wire tension force in the unwrapping wire process keep constant.
The invention has the beneficial effects as follows that mechanism can regulate steel wire automatically and keep the constant of steel wire tension in the unwrapping wire process.
Description of drawings:
Accompanying drawing is a schematic diagram of the present invention.1. damping chain, 2. extension spring, 3. balance pivot, 4. lever, 5. I-beam wheel, 6. support wire-crossing wheel, 7. steel wire, 8. wire-crossing wheel, 9. wire-crossing wheel, 10. damping wheel, 11. wire-crossing wheels, 12. strand wire-crossing wheels, 13. strand wire-crossing wheels, 14. plying wheels.
The specific embodiment
Steel wire (7) from I-beam wheel (5) pull out after wire-crossing wheel (8) to wire-crossing wheel (11) again through wire-crossing wheel (9) to plying wheel (14) to strand wire-crossing wheel (13) to strand wire-crossing wheel (12) through support wire-crossing wheel (6) to strander.
Go up steel wire (7) tension force partially during pine when wire-crossing wheel (8) and wire-crossing wheel (9), lever (4) be offset to the right, and it is big that " L " size becomes, tension damping chain (1), and the frictional resistance of increasing and damping wheel (10), thus tighten steel wire tension; Go up steel wire (7) when tension force is tight slightly when wire-crossing wheel (8) and wire-crossing wheel (9), lever (4) be offset left, and " L " size decreases is loosened damping chain (1), reduces and the frictional resistance of damping wheel (10), thereby transfers loose steel wire tension.
Claims (2)
