Description

Technical Field

[0001] The utility model relates to the technical field related to cold processing of large-disk heavy titanium alloy wires, in particular to large-disk heavy titanium alloy wire reforming and sizing cold processing equipment. Background Art

[0002] Titanium alloy materials have many excellent properties, such as light weight, high strength, and corrosion resistance. They can be used to manufacture important parts in the fields of aviation, aerospace, and ocean. Titanium alloy wires exhibit excellent mechanical properties in high-speed flight and harsh environments. Titanium alloy wires are difficult to process because titanium materials may undergo chemical reactions and need to be processed under special conditions such as high temperature and high pressure.

[0003] In order to obtain the ideal processing size, traditional titanium alloy wires are generally processed by hot rolling on a small horizontal rolling mill and multi-pass dead die hot drawing. Hot rolling can quickly change the wire diameter, but the rolling size tolerance is large and the ideal target size cannot be obtained. Sizing often requires multiple passes of hot drawing, resulting in low processing efficiency and high processing energy consumption of titanium alloy wires. Utility Model Content

[0023] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0025] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0026] See also Figure 1 to Figure 5 In the embodiment of the utility model, a large-plate heavy titanium alloy wire reforming and sizing cold processing equipment includes a damping pay-off drum 1, a multi-roller unwinding mechanism, a forced lubrication device 7, a vertical wire drawing machine 8, and an inverted wire drawing machine 9.

[0027] The details are as follows;

[0028] See also Figure 1 , Figure 3 , Figure 5 , including a damping pay-off drum 1, a multi-roller unwinding mechanism, a first wire drawing mechanism, and a second wire drawing mechanism sequentially arranged along the wire drawing direction, wherein the first wire drawing mechanism includes a forced lubrication device 7 and at least one set of vertical wire drawing machines 8, and the wire in the vertical wire drawing machine 8 moves upward;

[0029] The second wire drawing mechanism includes the forced lubrication device 7 and at least one set of inverted wire drawing machines 9, and the wire in the inverted wire drawing machines 9 moves downward.

[0030] In detail, in this embodiment, the large-coil heavy titanium alloy wire modification and sizing cold processing equipment described in the utility model is adopted. When in use, the large-coil heavy wire with processed head is placed in the damping pay-off reel 1 to ensure that the wire is smooth and not tangled during the uncoiling process. The wire passes through the multi-roller uncoiling mechanism in turn, and is led out to the predetermined position after uncoiling to complete the automatic uncoiling and feeding of the wire. The wire is transported to the first wire drawing mechanism. Under the action of the forced lubrication device 7, it is ensured that the wire can be smoothly connected to the vertical wire drawing machine 8, and the wire is hot-drawn for multiple times by combining the vertical wire drawing machine 8 with the inverted wire drawing machine 9, so that the total deformation of the wire is increased, and the wire can be quickly re-diametered and sizing.

[0031] Specifically, in one embodiment, the forced lubrication device 7 is installed with a dead die and lubricating drawing powder. The drawing powder is pressed by the device to squeeze the powder into the middle of the wire and the dead die during the drawing process, thereby fully lubricating the wire and allowing the wire to pass smoothly through the dead die and connect with the drawing reel. There is cooling circulating water in the mold installation position to cool the mold, complete the cold processing of the wire, and prevent the temperature from being too high, which would cause the drawing process to be interrupted.

[0032] It should be noted that the wire after drawing is wound on the take-up drum 10, and a rotatable roller is provided at the bottom of the take-up drum 10 to complete the collection and transfer of the processed wire.

[0033] Preferably, the inverted wire drawing machine 9 includes a motor and a reducer, and the motor and the reducer are arranged at the upper end of the wire, and drive the wire to move downward through a transmission method such as a chain or gear. The wire encounters less resistance during the downward movement, and the difficulty of continuous drawing without stopping is solved, which can speed up the wire drawing speed and improve production efficiency.

[0034] Preferably, a magnetic powder brake 2 is fixedly connected to the rotating shaft of the damping pay-off disk 1, and the magnetic powder brake 2 includes an input shaft and an output shaft, the output shaft is fixedly connected to the rotating shaft, and the input shaft is connected to the motor, so that the wire can be smoothly untangled during the unwinding process, thereby accelerating the wire drawing speed.

[0035] See also Figure 3 The multi-roller unwinding mechanism includes a support platform and a limiting roller 3, a pinch roller 4, a first straightening roller 5, and a second straightening roller 6 arranged on the support platform.

[0036] Preferably, the limiting roller 3 includes a symmetrically arranged horizontal roller and a vertical roller, and the horizontal roller and the vertical roller are rotatably installed on the support platform, and the horizontal roller and the vertical roller are perpendicular to each other. The wire passes through the gap between the horizontal roller and the vertical roller, and multi-directional adjustment of the limiting position of the steel wire entering the first wire drawing structure is realized, ensuring that no resistance is generated during the wire drawing process.

[0037] Preferably, the pinch rollers 4 include symmetrically arranged rollers, which are rotatably mounted on the support table, so that the wire enters subsequent processing equipment and maintains appropriate tension to ensure smooth processing of the wire.

[0038] The first straightening roller 5 includes a plurality of flat straightening rollers which are parallel to the support platform and are rotatably mounted on the support platform.

[0039] The second straightening roller 6 includes a plurality of vertical straightening rollers which are perpendicular to the support platform, and the vertical straightening rollers are rotatably mounted on the support platform.

[0040] Furthermore, the flat straightening roller and the vertical straightening roller move the wire forward while they are subjected to uniform radial and axial forces during the rotation process. This allows the wire to undergo continuous plastic and elastic deformation in the radial and axial directions, thereby achieving the purpose of straightening and reducing the size of the wire. At the same time, it can eliminate defects and unevenness on the wire surface, and also make the wire surface smooth and increase its strength.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
