Description

Technical Field

[0001] This utility model belongs to the technical field of electrode cleaning devices, and relates to a roller device for cleaning the surface of titanium alloy consumable electrodes. Background Technology

[0002] Titanium alloys possess advantages such as high specific strength, good high-temperature performance, and excellent corrosion resistance, making them widely used in aerospace, medical, and shipbuilding industries. Currently, the most widely used smelting method in industrial production is vacuum consumable arc melting (VAM). VAM requires the preparation of titanium alloy consumable electrodes, which are typically made by mixing sponge titanium with alloy raw materials (such as Al, V, Mo, etc.), pressing them into shape, and then assembling and welding them together. The preparation process of titanium alloy consumable electrodes generally includes: first, mixing sponge titanium and alloy raw materials according to a specific ratio; then pressing the mixed raw materials into electrode blocks using a hydraulic press; then assembling multiple electrode blocks and welding them together in a vacuum plasma welding box to form a long titanium alloy consumable electrode; finally, assembling it in a vacuum VAM furnace and welding it with auxiliary electrodes before smelting to obtain an ingot.

[0003] During the aforementioned manufacturing process, when multiple electrode blocks are welded into a long titanium alloy consumable electrode, molten metal spatter particles will appear at and near the welding point (which can be called the weld seam). Similarly, when welding the electrode to the auxiliary electrode in a vacuum consumable arc furnace, molten metal spatter particles will adhere to the surface of the consumable electrode. Before smelting the titanium alloy consumable electrode, these molten metal spatter particles must be removed from its surface to ensure product quality and prevent them from falling directly into the molten titanium alloy pool during the smelting process and causing metallurgical defects due to incomplete melting.

[0004] Defects and causes of existing technical methods: Because welds are typically annular, the surface of titanium alloy consumable electrodes needs to be inspected and cleaned. When operators use tools to remove spatter particles, they need to flip the titanium alloy consumable electrodes to ensure thorough cleaning of the entire surface. However, the significant weight of titanium alloy consumable electrodes makes flipping them difficult. Furthermore, flipping non-cylindrical titanium alloy consumable electrodes can cause vibrations that may crack the weld, affecting the welding quality. These reasons make the cleaning of titanium alloy consumable electrodes quite challenging. Utility Model Content

[0005] The purpose of this invention is to provide a roller device for cleaning the surface of titanium alloy consumable electrodes, which solves the problem that the vibration caused by flipping the titanium alloy consumable electrode during cleaning leads to weld cracking.

[0006] The technical solution adopted in this utility model is a roller device for cleaning the surface of titanium alloy consumable electrodes, including at least two roller assemblies. Each roller assembly includes a support base and a nested ring. At least two roller mechanisms are installed on the top of the support base. The nested ring is mounted on the top of the roller mechanism. The nested ring is made of pure titanium. The outer side of the nested ring is a rolling outer ring, and the inner side is a stop inner ring. The stop inner ring is used to fit around the outside of the titanium alloy consumable electrode and to circumferentially limit the titanium alloy consumable electrode.

[0007] The roller mechanism includes a rotating shaft and a bearing assembly. The rotating shaft is mounted on a support base, and the bearing assembly is fitted onto the rotating shaft.

[0008] The inner ring of the bearing assembly is interference-fitted with the shaft, or the bearing assembly is connected to the shaft by a key.

[0009] The support base includes a base and a mounting bracket. The mounting bracket is fixed on the base, and the rotating shaft is mounted on the top of the mounting bracket.

[0010] The base is in the form of a rectangular plate or a cross-shaped plate structure.

[0011] The outer rolling ring is circular or elliptical.

[0012] The shape of the stop inner ring matches the radial cross-sectional shape of the titanium alloy consumable electrode.

[0013] The inner stop ring is hexagonal in shape.

[0014] The stop inner ring consists of two opposing planes, two opposing arc surfaces, and four connecting surfaces, which are used to connect the arc surfaces and the planes.

[0015] The outer ring of the bearing assembly has an annular groove on its side, and the rolling outer ring of the nested ring is nested in the annular groove.

[0016] The beneficial effects of this utility model include: a roller device for cleaning the surface of titanium alloy consumable electrodes is assembled from a support base, a roller mechanism, and a nested ring, resulting in a simple structure; the nested ring is mounted on top of the roller mechanism, with its outer side being a rolling outer ring, allowing it to roll relative to the roller mechanism; and its inner side being a stop inner ring, used to place the titanium alloy consumable electrode to be cleaned and to prevent the electrode from rotating relative to the nested ring. When cleaning the titanium alloy consumable electrode, the roller device is placed near both ends of the electrode, and the nested ring is placed over both ends to clean the metal spatter particles generated during welding. After cleaning the upper side of the electrode, the nested ring is rotated to rotate the electrode so that the other side faces upward. The rotation process is easy and effortless, and there is no vibration when flipping a non-cylindrical titanium alloy consumable electrode, ensuring the welding effect of the weld.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1 See Figure 1 and Figure 2A roller device for cleaning the surface of a titanium alloy consumable electrode includes at least two roller assemblies 10. Each roller assembly 10 includes a support base 1 and a nested ring 3. Two roller mechanisms 2 are mounted on the top of the support base 1. The nested ring 3 is mounted on top of the two roller mechanisms 2. The outer surface of the nested ring 3 is a rolling outer ring 31, and the inner surface is a stop inner ring 32. The stop inner ring 32 is used to fit around the outside of the titanium alloy consumable electrode 4 and to circumferentially limit the titanium alloy consumable electrode. That is, in the rotation direction of the nested ring, the titanium alloy consumable electrode is engaged with the stop inner ring 32 to circumferentially limit the titanium alloy consumable electrode and prevent relative rotation between the titanium alloy consumable electrode and the nested ring. This allows the titanium alloy consumable electrode to rotate together with the nested ring, thereby driving the titanium alloy consumable electrode to rotate by rotating the nested ring. It is understood that the radial cross-sectional shape of the titanium alloy consumable electrode in this embodiment of the present invention is non-circular, so that the titanium alloy consumable electrode can be engaged with the stop inner ring 32.

[0020] The nested ring is made of pure titanium, which will not cause cross-contamination of the titanium alloy consumable electrode to be cleaned by other metal elements.

[0021] The roller mechanism 2 includes a rotating shaft 21 and a bearing assembly 22. The rotating shaft 21 is mounted on the support base 1, and the bearing assembly 22 is sleeved on the rotating shaft 21. The bearing assembly is a ball bearing, including an inner ring, an outer ring, and balls. The inner ring of the bearing assembly 22 is interference-fitted with the rotating shaft 21.

[0023] See Figure 4 In this embodiment of the invention, the roller device for cleaning the surface of a titanium alloy consumable electrode includes two roller assemblies 10 as an example. The titanium alloy consumable electrode is supported by the two roller assemblies 10. That is, by assembling the titanium alloy consumable electrode on the two roller assemblies 10, the titanium alloy consumable electrode can rotate with the nested ring, thereby reducing the cleaning difficulty of the titanium alloy consumable electrode. When the length of the titanium alloy consumable electrode is long, three, four, or more roller assemblies 10 can also be used to support the titanium alloy consumable electrode. This embodiment of the invention does not limit this.

[0024] In one alternative embodiment, the thickness of the nested ring 3 can range from 3 cm to 20 cm. For example, the thickness of the nested ring 3 can be 3 cm, 5 cm, 7 cm, 10 cm, 15 cm or 20 cm.

[0025] When using the roller device for cleaning the surface of titanium alloy consumable electrodes according to this invention, after the titanium alloy consumable electrode welding is completed, a crane is used to lift the titanium alloy consumable electrode out of the vacuum plasma welding box or vacuum consumable arc furnace. The titanium alloy consumable electrode is placed horizontally, and a nesting ring is fitted onto both ends of the titanium alloy consumable electrode. The ratio between the shortest distance between the placement position of the nesting ring and the end of the titanium alloy consumable electrode and the length of the titanium alloy consumable electrode can range from 5% to 35%. For example, the ratios between the shortest distance between the placement position of the nesting ring and the end of the titanium alloy consumable electrode and the length of the titanium alloy consumable electrode are: 5%, 10%, 15%, 20%, 25%, 30%, and 35%. The shortest distance between the placement position of the nesting ring and the end of the titanium alloy consumable electrode refers to the distance between the placement position of the nesting ring and the end of the titanium alloy consumable electrode along the length direction of the titanium alloy consumable electrode.

[0026] Place the titanium alloy consumable electrode with nested rings on the support base according to the corresponding distance of the nested rings. Clean the metal spatter particles generated by welding on the surface of the titanium alloy consumable electrode. After cleaning the upper side of the titanium alloy consumable electrode, rotate the other side of the titanium alloy consumable electrode to face upwards and clean the upper side of the rotated titanium alloy consumable electrode.

[0027] After cleaning the titanium alloy consumable electrode, use an overhead crane to lift the titanium alloy consumable electrode and remove the nested rings fitted at both ends of the titanium alloy consumable electrode to complete the cleaning work.

[0028] Example 2 A roller device for cleaning the surface of a titanium alloy consumable electrode includes three roller assemblies 10. Each roller assembly 10 includes a support base 1 and a nested ring 3. Two roller mechanisms 2 are mounted on the top of the support base 1. The nested ring 3 is mounted on the top of the two roller mechanisms 2. The outer side of the nested ring 3 is a rolling outer ring 31, and the inner side is a stop inner ring 32. The stop inner ring 32 is used to fit around the outside of the titanium alloy consumable electrode 4 and to circumferentially limit the titanium alloy consumable electrode.

[0029] The nested ring is made of pure titanium, which will not cause cross-contamination of the titanium alloy consumable electrode to be cleaned by other metal elements.

[0050] The nested ring is made of pure titanium, which will not cause cross-contamination of the titanium alloy consumable electrode to be cleaned by other metal elements.

[0057] Example 6 A roller device for cleaning the surface of titanium alloy consumable electrodes includes at least two roller assemblies 10. Each roller assembly 10 includes a support base 1 and a nested ring 3. Two roller mechanisms 2 are mounted on the top of the support base 1, and the nested ring 3 is mounted on the top of the two roller mechanisms 2.

[0058] The roller mechanism 2 includes a rotating shaft 21 and a bearing assembly 22.

Both the shape of the stopping inner ring 32 and the radial cross-sectional shape of the titanium alloy consumable electrode are non-rotational. Non-rotational shapes generally refer to parts or structures whose cross-sectional shapes do not have rotational symmetry. In this way, the nested ring 3 and the titanium alloy consumable electrode can achieve directional transmission. For example, the shape of the stopping inner ring 32 can include a regular polygon or a partial circle, such as a square, hexagon, triangle, or D-shape.

In this embodiment of the invention, by employing a design where the shape of the inner retaining ring 32 matches the radial cross-sectional shape of the titanium alloy consumable electrode, the risk of slippage of the titanium alloy consumable electrode during rotation with the nested ring can be reduced through multi-faceted contact. Simultaneously, it can also evenly distribute the load, reducing stress concentration and localized point loads, lowering the risk of fretting wear and fatigue cracks, thereby extending service life.

[0062] The outer ring side of the bearing assembly 22 has an annular groove 23, and the rolling outer ring 31 of the nested ring 3 is partially nested in the annular groove 23, which improves the stability of the nested ring during rotation.
