Description

Technical Field

[0001] The utility model relates to the technical field of titanium wire production and processing, in particular to a high-precision and high-efficiency titanium wire cold processing device. Background Art

[0002] Titanium wire is a thin filamentary product made from titanium material through a processing technique. It has excellent properties such as light weight, high strength, and corrosion resistance, and is widely used in various fields. The production process of titanium wire mainly includes raw material preparation, smelting, drawing, annealing and surface treatment. Among them, the smelting process requires controlling the smelting temperature and atmosphere to ensure the purity and uniformity of the titanium material; the drawing process requires controlling the temperature, stretching speed and mold size to ensure the quality and dimensional accuracy of the titanium wire; annealing treatment eliminates stress and grain boundaries in the titanium wire through heating and cooling, improving its plasticity and strength; surface treatment removes the oxide layer, improves surface finish and corrosion resistance through pickling, polishing or electroplating.

[0003] When drawing titanium wire, the commonly used processing method is heating furnace + mold + lubricating medium. The titanium wire is placed in a heating furnace for heating treatment to reach a suitable drawing temperature; the heated titanium wire is then fed into the mold, and the traction force of the drawing machine is used to gradually force the titanium wire through the mold channel; during the drawing process, lubricant is sprayed onto the mold and titanium wire surface through a nozzle to reduce friction and wear.

[0004] However, during the production process, it was discovered that using hot working methods consumes a large amount of energy, such as electricity or fuel. Moreover, after processing, the titanium wire needs to be cooled to return to room temperature, resulting in a long processing cycle. To this end, we proposed a high-precision and high-efficiency titanium wire cold working device to effectively address these drawbacks. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example: See Figures 1 to 8 A high-precision and high-efficiency titanium wire cold working device comprises a workbench 1. Upper and lower positioning dies 2, front and rear shaping cold drawing dies 3, and upper and lower shaping cold drawing dies 4 are sequentially arranged on the working surface of the workbench 1 along the drawing direction of the titanium wire material. The titanium wire material is shaped by cold working, which does not require heating of the titanium wire during the cold working process, thereby significantly reducing energy consumption. Furthermore, the need for complex heating and cooling processes shortens the processing cycle and improves production efficiency.

[0028] Among them, Figure 3 As shown, the upper and lower positioning molds 2 include a connecting base 201 that is detachably mounted on the workbench 1. The detachable design facilitates the inspection or replacement of the various components on the connecting base 201, and also allows the upper and lower positioning molds 2 to be replaced as a whole. A connecting groove 202 runs horizontally through the connecting base 201, providing installation space for other components in the mold. Two positioning rollers 203 are distributed vertically within the connecting groove 202. An annular positioning groove 204 is provided on the roller surface of each positioning roller 203 for vertical positioning of the titanium wire material. The titanium wire material passes between the two annular positioning grooves 204, thereby enabling the titanium wire material to be positioned. A first vertical spacing adjustment component 205 is provided on the connecting base 201 for adjusting the distance between the two positioning rollers 203, making it convenient to handle titanium wire materials of different sizes.

[0029] Preferably, Figure 3 and Figure 4 As shown, a first through slot 206 that is in communication with the connecting slot 202 is provided on one side of the connecting base 201, and a sealing plate 207 is detachably connected to the other side of the connecting base 201. In this embodiment, the sealing plate 207 is detachably connected to the connecting base 201 by screws, which has a simple structure and is easy to assemble and disassemble. When the sealing plate 207 is opened, it is convenient to inspect or replace the various components in the connecting slot 202. A second through slot 208 that is in communication with the connecting slot 202 is provided on the sealing plate 207. The first through slot 206, the second through slot 208 and the connecting slot 202 cooperate to form a cross shape. The widths of the first through slot 206 and the second through slot 208 are both smaller than the width of the connecting slot 202, so that the cross-shaped structure is larger inside and smaller outside, thereby making it difficult for other components inside the cross-shaped structure to come into contact with the outside world and avoid damage. The width of the positioning roller 203 is smaller than the width of the first through slot 206 and the second through slot 208 . Part of the positioning roller 203 is located outside the first through slot 206 and the second through slot 208 , making it easier for the operator to pass the titanium wire material between the two positioning rollers 203 .

[0030] Further, such as Figure 5As shown, the first upper and lower spacing adjustment assembly 205 includes adjustment bolts 2051 threadedly connected to the upper and lower ends of the connecting base 201. Each adjustment bolt 2051 is arranged in a vertical direction, and the tail end extends into the connecting groove 202. A convex plate 2052 that fits the inner surface of the connecting base 201 is rotatably connected to the tail end of each adjustment bolt 2051. A rolling shaft 2053 is rotatably connected to each convex plate 2052, and the positioning rollers 203 are respectively fixed to the corresponding rolling shaft 2053. When the distance between the two positioning rollers 203 needs to be adjusted, the adjustment bolt 2051 is rotated, driving the convex plate 2052 to slide downward or upward in the connecting groove 202, thereby adjusting the distance between the two positioning rollers 203, and thus being able to position titanium wire materials of different sizes. The structure is simple and easy to operate.

[0031] In this embodiment, if Figure 1 As shown, the connecting seat 201 moves along the vertical direction and penetrates the workbench 1. Side panels are fixedly connected to the front and rear sides of the connecting seat 201. Each side panel is fixedly connected to the top of the workbench 1 by screws. The connecting seat 201 is detachably connected to the workbench 1 through the cooperation of the side panels and the screws. It has a simple structure, is easy to disassemble and assemble, and is convenient to operate the adjusting bolt 2051 at the bottom of the connecting seat 201.

[0032] Secondly, if Figure 6 and Figure 7 As shown, the front-to-back shaping cold-drawing die 3 comprises a fixed base 301 removably mounted on a workbench 1. Wings are fixedly connected to the front and rear sides of the fixed base 1. Each wing is screwed to the top of the workbench 1. The fixed base 301 is removably connected to the workbench 1 through the cooperation of the wings and screws. The simple structure and easy assembly and disassembly facilitate repair and replacement of various components on the fixed base 301, and the front-to-back shaping cold-drawing die 3 can also be replaced as a whole. A fixed groove 302 is horizontally defined within the fixed base 301. Two first cold-drawing rollers 303 are positioned front and back within the fixed groove 302. Each first cold-drawing roller 303 has a first annular contouring groove 304 formed on its surface for shaping the titanium wire material front-to-back. The contouring is designed according to the desired shape of the titanium wire. The titanium wire material passes between the two first annular contouring grooves 304, thereby enabling front-to-back shaping of the titanium wire material. A front-to-back spacing adjustment assembly 305 is provided on the fixing seat 301 for adjusting the distance between the two first cold drawing rollers 303 , enabling the titanium wire material to be processed to a desired size. The structure of the front-to-back spacing adjustment assembly 305 is the same as that of the first upper and lower spacing adjustment assembly 205 .

[0033] The upper and lower shaping cold-drawing dies 4 include a removable mounting base 401 mounted on the workbench 1. The mounting base 401 is removable in the same manner as the connecting base 201, facilitating repair and replacement of components on the mounting base 401 and allowing for complete replacement of the upper and lower shaping cold-drawing dies 4. A mounting slot 402 runs horizontally through the mounting base 401. Two second cold-drawing rollers 403 are positioned vertically within the mounting slot 402. Each second cold-drawing roller 403 has a second annular contoured groove 404 formed on its surface for shaping the titanium wire material vertically. The contoured grooves are designed to correspond to the desired shape of the titanium wire. Once the titanium wire material passes between the two second annular contoured grooves 404, it is shaped vertically. A second vertical spacing adjustment assembly 405 is provided on the mounting base 401 for adjusting the distance between the two second cold-drawing rollers 403, enabling the titanium wire material to be processed to the desired size. The structure of the second vertical spacing adjustment assembly 405 is identical to that of the first vertical spacing adjustment assembly 205.

[0034] In this embodiment, it should be noted that, among the upper and lower positioning molds 2, the front and rear molding cold drawing molds 3 and the upper and lower molding cold drawing molds 4, except for the annular positioning groove 204, the first annular profiling groove 304 and the second annular profiling groove 404 which need to be specially customized according to needs, the other structures are basically the same, which is convenient for processing and assembly of various components.

[0035] During use, the titanium wire is passed sequentially through the two annular positioning grooves 204, the two first annular contouring grooves 304, and the two second annular contouring grooves 404. The adjusting bolts 2051 are then rotated using a wrench to ensure that the titanium wire is in close contact with the positioning rollers 203, the first cold drawing roller 303, and the second cold drawing roller 403. Finally, the titanium wire is drawn through the drawing machine. The drawn titanium wire is inspected and then passed through the two annular positioning grooves 204, the two first annular contouring grooves 304, and the two second annular contouring grooves 404 in sequence. The adjusting bolts 2051 are then rotated, and the drawing process is repeated until the desired size is achieved.
