Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire pay-off machines, in particular to a constant tension wire pay-off machine. Background Art
[0002] On the oil quenching and tempering production line, the steel wire is evenly paid out by the pay-off machine, quenched and tempered by the quenching furnace and the tempering furnace, and finally wound up by the take-up machine. The pay-off machine plays a vital role. The pay-off speed, pay-off tension and pay-off mode will affect the quality of the quenching and tempering of the steel wire. Fluctuations in the pay-off speed cause fluctuations in the mechanical properties of the steel wire. Excessive tension causes the steel wire to be thinned, while too little tension causes distortion. The quality of steel wire processed by different pay-off modes will also be different. Currently, there are two types of equipment in use: active pay-off machines and passive pay-off machines. Different pay-off machines will be selected for different thicknesses of flat steel wire. Active pay-off machines are used for thin steel wires to prevent thin steel wires from being thinned during the pay-off process. Passive pay-off machines are used for thick steel wires to prevent thick steel wires from being twisted during the pay-off process.
[0003] The inventors of the present application discovered the following problem when using existing equipment: During on-site production of flat steel wires of different thicknesses, the active pay-off machine and the passive pay-off machine need to be moved back and forth, which consumes manpower and affects production efficiency. Utility Model Content
[0004] In order to solve the problem of switching back and forth between an active pay-off machine and a passive pay-off machine according to the thickness of the flat steel wire during the production process, the utility model provides a constant tension pay-off machine, and the specific technical scheme is as follows:
[0005] A constant tension wire-paying machine comprises a frame; a wire-paying device arranged on one side of the frame, the wire-paying device comprising a wire-paying wheel, the outer peripheral side of the wire-paying wheel being wound with wire; and a floating device arranged on the same side of the frame as the wire-paying device, the floating device comprising a floating tensioning wheel whose outer peripheral side is tangent to the wire; a wire-guiding device arranged on the same side of the frame as the wire-paying device, the wire-guiding device comprising a first wire-guiding wheel and a second wire-guiding wheel parallel to the axis of the first wire-guiding wheel.
[0006] Preferably, the first guide wheel, the second guide wheel, the pay-off wheel and the floating tension wheel axis are parallel.
[0007] Preferably, the pay-off device further comprises a pay-off motor, which transmits its own power to the pay-off wheel through a transmission mechanism.
[0008] Preferably, the floating device further comprises a floating shaft arranged at the center of the floating tensioning wheel, the axis of the floating shaft is parallel to the floating tensioning wheel, and the floating shaft drives the floating tensioning wheel to slide along the frame.
[0009] Furthermore, the mass of the floating tension wheel is in the range of 0.8-1.5KG.
[0010] Preferably, the outer peripheral sides of the pay-off wheel, the floating tension wheel, the first guide wheel and the second guide wheel are all formed with U-shaped grooves. It can be seen from the above technical solution that the utility model has the following beneficial effects:
[0011] In the active wire-releasing mode, the utility model always applies pressure to the flat wire through the deadweight of the floating tension wheel to control the wire tension; in the passive wire-releasing mode, the utility model limits the left and right movement of the flat wire through the first and second wire wheels with grooves formed on the outer peripheral side.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0018] like Figures 1 to 2As shown, an embodiment of the utility model includes a frame 1, and a pay-off device 2 is rotatably connected to the left side of the frame 1. The pay-off device 2 includes a pay-off motor 22 fixedly connected to the bottom surface of the frame 1, and the output end of the pay-off motor 22 transmits power to a pay-off wheel 21 rotatably connected to the left side of the frame 1 through a transmission mechanism 23. The transmission mechanism 23 can adopt a sprocket drive or a gear drive. A groove for winding a flat wire is formed on the outer peripheral side of the pay-off wheel 21, and its axis is perpendicular to the left side of the frame 1.
[0019] Secondly, the wire guide device 5 arranged on the left side of the frame 1 includes a first wire guide wheel 51 rotatably connected above the pay-off wheel 21. The first wire guide wheel 51 is provided with two and its axis is perpendicular to the left side of the frame 1. The flat wire passes through the gap between the two first wire guide wheels 51, which can limit the position of the wide and narrow sides of the flat wire during the movement, ensuring that the wide and narrow sides of the flat wire released from the embodiment of the utility model meet the processing requirements of subsequent quenching and tempering. The wire guide device 5 also includes two second wire guide wheels 52, the outer peripheral side of the second wire guide wheel 52 is formed with a groove for placing the flat wire, and the middle surface of the groove coincides with the middle surface of the first wire guide wheel 51, and the axis of the second wire guide wheel 52 is parallel to the axis of the first wire guide wheel 51.
[0020] In addition, the flat wire passes through the first second wire wheel 52 and then through the floating device 3. The floating device 3 includes a floating shaft 32 slidably connected to the frame 1, and the movement direction of the floating shaft 32 is perpendicular to the axis of the wire pay-off wheel 21 in the projection of the direction of the wire pay-off wheel 21. A floating tension wheel 32 is fixedly connected to the outer peripheral side of the floating shaft 32, and the axis of the floating tension wheel 32 is parallel to the first and second wire wheels, and its middle surface coincides with the middle surface of the first and second wire wheels.
[0021] In the active pay-off mode of the embodiment of the utility model, thin flat wire is released from the pay-off wheel 21, passes through the first and second wire wheels, and then passes through the floating tension wheel 31. When the tension of the flat wire is relatively small, the floating tension wheel 31 relies on its own weight of 0.8-0.5KG to press down the flat wire tangent thereto, thereby increasing the tension of the flat wire. However, when the floating tension wheel 31 drops to its stroke limit, the rotation speed of the pay-off motor 22 decreases, thereby reducing the speed at which the pay-off wheel 21 pays out the flat wire. When the processing speed of the subsequent process of the flat wire remains unchanged, the speed of releasing the flat wire is reduced, and the tension of the flat wire will slowly increase to the required range.
[0022] When the tension of the flat wire is large, the floating tensioning wheel 31 moves up along the frame 1 under the action of the flat wire to reduce the tension of the flat wire. However, when the floating tensioning wheel 31 moves up to its stroke limit, the rotation speed of the pay-off motor 22 is accelerated, thereby increasing the speed at which the pay-off wheel 21 pays out the flat wire. When the processing speed of the subsequent process of the flat wire remains unchanged, the speed of releasing the flat wire is increased, and the tension of the flat wire will slowly decrease to the required range.
[0023] In the passive pay-off mode of the embodiment of the utility model, the thick flat wire does not pass through the floating tensioning wheel 31, but only passes through the conductor device 5, and is pulled by a subsequent take-up machine (not shown in the figure) to perform heat treatment.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
