[0002] In the production of steel cord and hose wire busbar, processes such as dry drawing and thermal diffusion electroplating are required. During the dry drawing process, in order to prevent direct hard grinding between the steel wire and the mold, the steel wire needs to be treated with boron coating. The good adsorption of the boron coating layer is utilized to increase the amount of powder to ensure the necessary lubrication between the steel wire and the mold so that the drawing can proceed normally.
[0003] In the existing process, after the steel wire is coated with boron and dried, it must first pass through the soap powder box of the wire drawing die to make the surface of the steel wire have lubricating powder, and then be drawn out through the die box to produce a small-section steel wire. In this process, the cross-section of the steel wire is often round and straight, resulting in insufficient lubricating powder, causing failure in lubrication of the steel wire surface, resulting in damage to the die, wire expansion, etc. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.
[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.
[0021] This embodiment provides a device for increasing the amount of powder in steel wire dry drawing, such as Figure 1-2As shown, it includes a steel wire deformation mechanism 1 arranged at the entrance of the steel wire dry-drawing soap powder box, through which the steel wire deformation mechanism 1 is squeezed and deformed, and the steel wire deformation mechanism 1 includes a group of relatively arranged annular rotating bodies 2, the rotating shaft of the rotating body 2 is arranged perpendicular to the moving direction of the steel wire, and 7 convex units 3 are evenly distributed along the circumference of the outer edge of the rotating body 2, and grooves 4 are formed between each adjacent convex unit 3. When the rotating body 2 is rotated by the engagement of the convex unit 3 and the groove 4, a steel wire channel 5 is formed between the meshing convex unit 3 and the groove 4, and the steel wire is passed through the steel wire channel 5 between the meshing convex unit 3 and the groove 4, and the shape of the steel wire is changed before the steel wire enters the entrance of the steel wire dry-drawing soap powder box, thereby increasing the amount of powder carried by the steel wire, improving the lubrication effect, and greatly reducing mold damage and the occurrence of steel wire expansion.
[0022] In this embodiment, the steel wire deformation mechanism 1 is detachably connected to the steel wire dry-drawing soap powder box, which is convenient for disassembling or replacing the steel wire deformation mechanism 1. Different steel wire deformation mechanisms 1 can be replaced according to steel wires of different diameters.
[0023] In this embodiment, Figure 1-2 As shown, the cross section of the convex unit 3 is an arc, which can deform the steel wire into a wavy shape. The diameter of the arc is 50 to 100 times the diameter of the steel wire, preventing the steel wire from losing strength and causing obvious mechanical damage due to extrusion when passing through the steel wire channel 5. The central angle of the arc is 35° to 55°.
[0024] In this embodiment, Figure 1-3 As shown, the horizontal distance P of each adjacent arc is 1 mm to 5 mm, and the distance P of the adjacent arcs is 2.0 mm. After the steel wire passes through the steel wire deformation mechanism 1, the deformed steel wire obtained is as shown in FIG. Figure 3 As shown, half of the wavelength of the deformed steel wire is about 2.0 mm, that is, W≈P=2.0 mm. The bending portion of the deformed steel wire is an arc-shaped bend, which greatly increases the powder carrying capacity of the steel wire.
[0025] In this embodiment, the number of the convex units 3 is an odd number, and the number of the convex units 3 is greater than or equal to five.
[0026] When using the device, a steel wire deformation mechanism 1 that matches the diameter of the steel wire is selected, and the steel wire deformation mechanism 1 is installed at the steel wire entrance of the steel wire dry-drawn soap powder box, so that the axis of the rotating body 2 is perpendicular to the movement direction of the steel wire entering the steel wire dry-drawn soap powder box, and the installation of the steel wire deformation mechanism 1 is completed. Then, the end of the steel wire is inserted between two oppositely arranged rotating bodies 2 from the side of the steel wire deformation mechanism 1 away from the steel wire dry-drawn soap powder box, and the end of the steel wire is inserted from the steel wire deformation mechanism 1 close to the steel wire dry-drawn soap powder box through the steel wire channel 5 formed between the meshing convex unit 3 and the groove 4. The steel wire is passed out from one side, and the steel wire is passed through the steel wire entrance of the steel wire dry-drawn soap powder box. The steel wire is pulled under the action of external force. When the steel wire passes through the steel wire channel 5, the meshing convex unit 3 and the groove 4 squeeze the steel wire, so that the steel wire changes from a straight line to a wavy shape. During the movement of the steel wire, the rotating body 2 is driven to rotate, so that the subsequent convex unit 3 and the groove 4 are meshed, and the steel wire is squeezed and deformed. The wavy steel wire enters the steel wire dry-drawn soap powder box under the action of external force, and the bending part of the wavy steel wire brings more powder into the mold, which has a better lubrication effect.
[0027] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
