Description

Technical Field

[0001] This invention relates to the field of metal wire drawing, particularly to the drawing of ultra-fine wires, and to a wire drawing tension buffer device based on magnetic materials. Background Technology

[0002] With the widespread adoption of wireless charging for mobile phones in the 3C industry, the ultra-thin and miniaturized design of charging transmitters and the continuous improvement of charging power have increased the requirements for the number of coil turns. Due to the miniaturization design, the space left for the coil by the ferrite core has become narrow, thus requiring increasingly finer diameter enameled wire. Since the body of the enameled wire is still copper wire, the wire drawing process has become an unavoidable choice. During the processing of enameled wire, it is necessary to pass through a die, which places requirements on the consistency of the diameter after drawing. After the wire is uniformly stretched to within 0.1mm, the tensile strength of the wire is extremely low. When changing the take-up tray without stopping the machine during production, or when the machine is stopped to check and calibrate the instruments before starting the wire again, the take-up tension is extremely unstable, making the wire very easy to break; this affects production efficiency and leads to an increase in production costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wire drawing tension buffer device based on magnetic materials.

[0004] The objective of this invention is achieved through the following technical solution: a wire drawing tension buffer device based on magnetic materials, the device comprising an equipment mounting plate and a bracket mounted thereon, a slider bearing plate mounted on the bracket, and a slider seat mounted via a linear guide rail; The slider seat is equipped with a sliding winding wheel assembly, and the slider support plate is equipped with a fixed winding wheel assembly; the wire is wound around the fixed winding wheel assembly and the sliding winding wheel assembly after passing through the lead wire wheel, and then passes through the lead wire wheel. A round bar is mounted on the slider seat via a slider, and magnetic rings with mirrored magnetic poles are arranged sequentially on the round bar to buffer the tension of the wire by utilizing the principle of like poles repulsion.

[0005] Furthermore, the magnetic poles of the magnetic rings are axial and have the same thickness and consistent inner diameter.

[0006] Furthermore, the round bar material forms a clearance fit with the inner diameter of the magnetic ring.

[0007] Furthermore, the combination of the round bar and the magnetic ring is arranged in two parallel sets, and the symmetrical design ensures magnetic balance.

[0008] Furthermore, the linear guide rail is parallel to the round bar and perpendicular to the slider, so that the slider's travel direction is parallel to the magnetic force direction of the magnetic ring constraining the round bar.

[0009] Furthermore, the slider support plate is designed with two sets of mounting bracket positioning dimensions, which can achieve inverted installation.

[0010] The beneficial effects of this invention are as follows: Compared with the prior art, this invention uses the principle of like poles repulsion of multiple sets of magnetic rings, and then uses multiple sets in parallel to evenly disperse the magnetic force, thereby achieving effective buffering and improving production efficiency.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0015] like Figure 1 As shown, the present invention provides a wire drawing tension buffer device based on magnetic materials, including a device mounting plate and bracket, a slider support plate and slider seat, a fixed winding wheel group and a sliding winding wheel group, an inlet wire wheel and an outlet wire wheel; This invention utilizes the principle of like poles repulsion in rare earth magnets and the characteristic that magnetic force is not easily attenuated. Magnetic rings 204 with axial poles, the same thickness, and consistent inner diameter are selected and arranged sequentially after magnetic pole mirroring (one positive, one negative, one positive, and so on). Round bars 206 (stainless steel or ceramic bars can be used, but brass and copper bars are not allowed) with low permeability and gap fit with the inner diameter of the multiple arranged magnetic rings are used for axial series constraint. The round bars 206 are vertically fixed to the slider, which is assembled and fixed to the slider seat 207 by four screws. A symmetrical design ensures magnetic balance. The slider seat 207 is mounted on two linear guide rail seats 208 and assembled with linear guide rails 209. The linear guide rails 209 are mounted on the slider support plate 202. The slider seat 207 moves along the linear guide rails 209. The slider support plate 202 is designed with guide rail mounting positions to ensure that the linear guide rails 209 are parallel. One side of the linear guide rail 209 is fixed, while the other side can be freely assembled.

[0016] The linear guide 209 is parallel to the round bar 206 and perpendicular to the slider, so that the slider's travel direction is parallel to the magnetic ring constraining the round bar and the direction of magnetic force. This invention installs a pair of 15 sets of magnetic rings to maximize the utilization of magnetic force within a limited stroke. The device of this invention has an introductory guide wheel 203 on the right side, which is mounted on the slider support plate 202. It has ball bearings inside for rolling and is fixed in the fixed shaft by the length of the bushing, so that it is flush with the first winding wheel 104 in the fixed winding wheel group 103, reducing the chance of the line 101 detaching from the fixed winding wheel group 103. The line 101 passes through the introductory guide wheel 203 and is wound in sequence around multiple fixed winding wheel groups 103 and sliding winding wheel groups 105. Each wheel group is equipped with ball bearings for rolling. The sliding winding wheel group 105 is fixed on the slider seat 207. This invention adopts a combination of 15 fixed + 14 moving wheels, which are fixed on the mounting shaft by equidistant bushings. The line 101 passes through the guide wheel 102 on the left side of this invention and is fixed in the fixed shaft by the length of the bushing, so that it is flush with the last winding wheel 104 in the fixed winding wheel group 103, and enters the next station. The slider support plate 202 is designed with two sets of mounting bracket positioning dimensions. The slider support plate 202 is mounted on the bracket 205 through the mounting holes. The bracket 205 is mounted on the equipment mounting plate 201 according to the positioning holes, which can realize inverted installation. The dimensions of the equipment mounting plate 201 and the bracket can be designed to the required mounting hole positions of the wire drawing machine as needed. This invention does not fix them.

[0017] The above embodiments are used to explain and illustrate the present invention, but not to limit the present invention. Any modifications and changes made to the present invention within the spirit and scope of the claims shall fall within the protection scope of the present invention.
