Description

Technical Field

[0001] The invention belongs to the technical field of metal wire pickling equipment, and in particular relates to a tool for metal wire chemical treatment and a use method thereof. Background Art

[0002] Nickel-titanium shape memory alloys are widely used in medical devices such as pacemakers, heart valves, neurostimulators, neurovascular guidewires, vascular stents, artificial joints, and orthopedic implants. Different application fields require nickel-titanium wires with different surface states. The surface states of nickel-titanium alloy wires can usually be divided into bright state, slightly oxidized state, and deeply oxidized state. The bright state surface is widely used in medical implants such as stents and catheters due to its good biocompatibility and corrosion resistance.

[0003] Usually, a bright surface can be obtained by mechanical polishing and chemical treatment. However, for small-sized wires, the mechanical polishing effect is poor and the wire straightness will be affected. The chemical treatment of the wire surface oxide layer has no requirements for the wire size. Therefore, for small-sized wires, the chemical treatment of the surface is more effective.

[0004] The traditional chemical treatment method is usually to wind the wire on a wheel and then put the whole wire into the chemical treatment liquid to make it react chemically during immersion. However, this method is prone to partial undertreatment or overtreatment, which affects the final finish and consistency of the wire. Summary of the invention

[0005] The purpose of the present invention is to provide a tool for chemical treatment of metal wires and a method of use, so as to improve the contact uniformity between the wires and the chemical treatment liquid.

[0012] Further, the axial spacing between adjacent meshes is greater than the axial distance between the meshes;

[0013] The circumferential spacing between adjacent meshes is greater than the circumferential distance between the meshes.

[0014] Furthermore, a plurality of sleeves are arranged outside the cylindrical shaft, and the sleeves are hollow cylindrical;

[0015] There are spacings between the plurality of sleeves;

[0016] Each sleeve has mesh holes thereon.

[0017] Furthermore, the arrangement of the mesh holes on the sleeve is the same as the arrangement of the mesh holes on the barrel shaft.

[0018] Furthermore, both ends of the sleeve are detachably connected to the sleeve cover.

[0019] Furthermore, the cylinder shaft is threadedly connected to the cylinder cover.

[0020] Further, a buckle is provided at the end of the sleeve;

[0021] A plurality of annular grooves are arranged at intervals on the cylinder cover;

[0022] The buckle is used to be inserted into the groove to achieve the connection between the sleeve and the cylinder cover.

[0023] Further, the following steps are included:

[0030] The beneficial effect of the present invention is that the present invention winds the metal wire around a hollow cylindrical shaft with mesh holes, so that during the chemical treatment process, the chemical treatment liquid can penetrate into the interior of the metal wire coil through the internal space of the shaft and the mesh holes, and combined with the chemical treatment liquid that penetrates through the outside of the metal wire coil, the contact area between the metal wire and the chemical treatment liquid can be increased, thereby improving the contact uniformity between the metal wire and the chemical treatment liquid.

[0036] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the traditional chemical treatment process, the contact area between some parts of the wire and the chemical treatment liquid is insufficient, which affects the effect and efficiency of the chemical treatment. In addition, due to the limitation of the contact area, the wire is prone to partial undertreatment or overtreatment during the chemical treatment process, which affects the final smoothness and consistency. Therefore, there is an urgent need for a chemical treatment tool to increase the contact area between the wire and the treatment liquid, thereby improving the chemical treatment effect.

[0038] It should be noted that the metal wire 40 referred to in the present invention refers to a metal wire 40 with a diameter in the range of 0.1 to 2.0 mm. The diameter of the metal wire 40 exceeding this range is too large and is not convenient for rewinding.

[0039] The present invention discloses a tool for chemical treatment of metal wires, such as Figure 1 As shown, it includes a cylinder shaft 10 and a cylinder cover 20; the cylinder shaft 10 is a hollow cylinder, and the cylinder covers 20 are respectively connected to its two ends; the cylinder cover 20 is an annular plate, and is detachably connected to the end of the cylinder shaft 10; a plurality of mesh holes 11 are opened on the cylinder shaft 10, and the mesh holes 11 extend from the inner wall surface of the cylinder shaft 10 to its outer wall surface.

[0040] The present invention winds the metal wire 40 around a hollow cylindrical shaft 10 having mesh holes 11. During the chemical treatment process, the chemical treatment liquid can penetrate into the interior of the metal wire coil through the internal space of the shaft and the mesh holes 11. Combined with the chemical treatment liquid that penetrates through the outside of the metal wire coil, the contact area between the metal wire 40 and the chemical treatment liquid can be increased, thereby improving the contact uniformity between the metal wire 40 and the chemical treatment liquid.

[0041] In one embodiment, a plurality of rows of meshes 11 are evenly distributed in the axial direction of the barrel shaft 10; two adjacent rows of meshes 11 are staggered. On the rewound metal wire roll, an area is formed between adjacent meshes 11, and the position on the metal wire roll corresponding to the area forms an area to be chemically treated. Through multiple rows of staggered meshes 11, the chemical treatment liquid can penetrate into the area to be chemically treated from different edge positions of the area to be chemically treated, so that the chemical treatment liquid can fully penetrate into each position of the metal wire 40, thereby improving the uniformity of the distribution of the chemical treatment liquid on the surface of the metal wire 40.

[0042] The height of the cylinder shaft 1 is selected to be 200-300 mm, the diameter is 100-150 mm, the length is 5:4 to the outer diameter of the cylinder cover, and the wall thickness is 5-7 mm. The upper and lower parts of the cylinder shaft are engraved with threads (internal or external threads) for assembly with the cylinder cover 10.

[0043] The axial spacing between adjacent meshes 11 is greater than the axial distance between the meshes 11; the circumferential spacing between adjacent meshes 11 is greater than the circumferential distance between the meshes 11. Since the chemical treatment liquid can penetrate all around a mesh 11, the area of ​​the above-mentioned area to be chemically treated can be increased, thereby reducing the number of meshes 11 and reducing the processing difficulty and processing cost of the cylindrical shaft 11.

[0044] In addition, the shape of the mesh 11 can be selected according to demand, and can be rectangular, circular, elliptical, star-shaped, or various non-standard shapes. The mesh 11 has a hole length of 10 to 16 mm, a width of 5 to 8 mm, a spacing of 8 to 10 mm between holes in the same row, and a spacing of 12 to 15 mm between holes in two rows. The holes in different rows are staggered.

[0045] The outer part of the cylindrical shaft 10 is also provided with a plurality of sleeves 30, such as Figure 2 As shown, the sleeve 30 is a hollow cylinder; there is a spacing between several sleeves 30; each sleeve 30 has a mesh 11. The metal wire roll can be divided into multiple small metal wire rolls by the sleeve 30. For example, when there is only a barrel 10, the metal wire roll has 100 layers of wire. When four sleeves 30 are provided, 25 layers of wire can be wound on the barrel 10, and 25 layers of wire can be wound on each sleeve 30, so that the number of layers of metal wire 40 that the chemical treatment liquid needs to penetrate is greatly reduced, so that the metal wire 40 and the chemical treatment liquid are in better contact, and the contact area is larger and more uniform.

[0046] The diameter of the sleeve 30 is larger than the diameter of the cylindrical shaft 10, and matches the spacing of the groove 21. The side uses a buckle to achieve a bite effect. When multiple sleeves 30 are used, the diameters of the multiple sleeves 30 gradually increase. When the diameter of the metal wire 40 is 0.1-0.5 mm, the wall thickness of the sleeve 30 is 0.5-1.0 mm. When the diameter of the metal wire 40 is 0.6-1.0 mm, the wall thickness of the sleeve 30 is 1.0-1.2 mm. When the diameter of the metal wire 40 is 0.6-1.0 mm, the wall thickness of the sleeve 30 is 1.2-1.5 mm.

[0047] When the diameter of the metal wire 40 is 0.1-0.5 mm and the number of winding layers is greater than 3 layers, the next sleeve 30 needs to be installed; when the diameter of the metal wire 40 is 0.6-1.0 mm and the number of winding layers is greater than 4 layers, the next sleeve 30 needs to be installed; when the diameter of the metal wire 40 is greater than 1.0 mm and the number of winding layers is greater than 5 layers, the next sleeve needs to be installed.

[0048] exist Figure 2 In the figure, A is the connection part of the sleeve 30. The two edges of the sleeve 30 are respectively processed with a male buckle and a female buckle. The buckle thickness is consistent with the sleeve thickness, and the buckle depth is 5mm to 15mm. When the diameter of the metal wire is 0.1 to 0.5mm, the buckle width is 10 to 15mm, when the diameter of the metal wire is 0.6 to 1.0mm, the buckle width is 15 to 20mm, and when the diameter of the metal wire is greater than 1.0mm, the buckle width is 20 to 25mm. The distance between the two buckles is 20 to 30mm.

[0049] In the present invention, the arrangement of the mesh holes 11 on the sleeve 30 is the same as the arrangement of the mesh holes 11 on the cylinder shaft 10. The uniform mesh arrangement is more conducive to the uniform distribution of the chemical treatment liquid.

[0050] Both ends of the sleeve 30 are detachably connected to the sleeve cover 20 , so that the sleeve 30 can be disassembled in time during the rewinding process of the metal wire 40 .

[0051] Since the barrel shaft 10 is a support member for the innermost metal wire 40 , it only needs to be installed between the rewinding of the metal wire 40 . Therefore, in the embodiment of the present invention, the barrel shaft 10 is threadedly connected to the barrel cover 20 to increase the stability of the connection between the two.

[0052] Regarding the specific connection method, a buckle is provided at the end of the sleeve 30; Figure 3 As shown, a plurality of annular grooves 21 are arranged at intervals on the cylinder cover 20; the buckle is used to be inserted into the groove 21 to realize the connection between the sleeve 30 and the cylinder cover 20. The two can be connected in a plug-in manner, which is convenient for disassembly and installation.

[0053] The width of the groove 21 is consistent with the thickness of the sleeve 30. When the diameter of the metal wire 40 is 0.1-0.5 mm, the groove spacing is 1-2 mm. When the diameter is 0.6-1.0 mm, the spacing is 2-3 mm. When the diameter is greater than 1.0 mm, the groove spacing is 3-4 mm.

[0054] The present invention also discloses a method for using a tool for chemical treatment of metal wires, comprising the following steps: assembling a barrel shaft 10 and a barrel cover 20, and rewinding a metal wire 40 on the barrel shaft 10; wherein the rewinding directions of two adjacent layers of the metal wire 40 are opposite; when the rewound metal wire 40 reaches a predetermined number of layers, installing a sleeve 30 on the outside of the barrel shaft 10, and passing the free end of the metal wire 40 through the sleeve 30 and then rewinding the metal wire 40; when the metal wire 40 rewound on the sleeve 30 reaches a corresponding number of layers, continuing to install the next layer of the sleeve 30, and continuing to rewind the metal wire 40 until the rewinding of the metal wire 40 is completed.

[0055] Installing the sleeve 30 includes: removing the cylinder cover 20 away from the free end of the metal wire 40, sleeve one end of the sleeve 30 to be installed on the outside of the cylinder shaft 10 / sleeve 30 wound with the metal wire 40 and connect it to another cylinder cover 20; and connect the removed cylinder cover 20 to the cylinder shaft 10 and the sleeve to be installed in turn.

[0056] like Figure 4 As shown, when the metal wire 40 is rewound for the first layer, the rewinding direction needs to be 30 to 60 degrees with the axial direction of the barrel shaft 10. When it is reversely rewound for the second layer, the rewinding direction needs to be 120 to 150 degrees with the axial direction of the barrel shaft 10. When it is rewound for the third layer, the rewinding direction needs to be 30 to 60 degrees with the axial direction of the barrel shaft 10. This process is repeated for the next layer until the rewinding is completed.
