Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy production equipment, in particular to a device for assisting in pressing a titanium alloy electrode block. Background Art

[0002] At present, in the smelting process of titanium alloy, vacuum consumable furnace is a mainstream production method. The consumable electrode used in the vacuum consumable furnace is pressed from sponge titanium and alloy mixture. In order to ensure the uniform composition of the ingot and no serious element enrichment and segregation, the pressed electrode block is required to have good density. The initial electrode of the electrode block welding is strictly prohibited from breaking, and the electrode does not fall off during the melting process.

[0003] However, whether it is industrial production or scientific research experiments, there must be a situation where the amount of alloy material added accounts for a large proportion. In the process of pressing the electrode block, even if the upper limit of the equipment nominal force is reached, it is difficult to ensure that the electrode block is compact and dense, resulting in axial cracks in the electrode block. Such cracks in the electrode block are difficult to remedy during the welding process. In this way, the consumable electrode is at risk of breaking, falling off, and raw materials falling off during the melting process, which not only poses certain safety hazards, but also affects the product quality of the ingot, seriously affecting production work and experimental research results. Summary of the invention

[0004] In view of the above problems, the purpose of the utility model is to provide a device for assisting in pressing titanium alloy electrode blocks, which is used to assist in pressing the initial electrode blocks for smelting titanium alloys, in order to prevent leakage of fine powder materials in the raw materials and poor adhesion of the alloy materials resulting in insufficient density of the pressed initial electrode blocks, and to avoid electrode breakage, block falling, etc. during the smelting process.

[0016] See attached Figure 1 The utility model proposes a device for assisting in pressing a titanium alloy electrode block, comprising a mold (1), an upper scale (2), a cover plate (3) and a bottom scale (4). In this embodiment, the mold (1) is a rectangular box-type structure; the cover plates (3) are provided with two pieces, which respectively cover the left and right side areas of the top of the mold (1), and the outer ends of the two cover plates (3) are respectively connected to the two side shafts of the top of the corresponding mold (1), and the cover plates (3) can be flipped. When flipped outward, the top of the mold (1) is in an open state, and when flipped inward, the top of the mold (1) is closed; the bottom surface of the mold (1) is an open structure.

[0017] The upper scale (2) is respectively arranged in the four corner areas of the upper part of the mold (1) and in the middle areas on the left and right sides, and the upper scale (2) in the four corner areas is arranged perpendicularly to the front and rear sides of the mold (1), and the upper scale (2) in the middle areas on the left and right sides is arranged perpendicularly to the left and right sides of the mold (1); the bottom scale (4) is respectively arranged in the four corner areas of the lower end surface of the mold (1) and is arranged perpendicularly to the lower end surface of the mold (1).

[0018] The outer surfaces of the upper scale (2) and the bottom scale (4) are both processed into a threaded shape and are connected to the mold (1) via threads, so that the length of the scale can be adjusted by rotation.

[0019] In this embodiment, the mold (1), the upper scale (2), the cover plate (3) and the bottom scale (4) are all made of titanium alloy; and the inner and outer walls and corners of the device are required to be polished smooth to ensure that the device does not introduce any foreign impurities during the pressing process of the electrode block.

[0020] The use of the utility model:

[0021] (1) Spread 1 / 3 of the total amount of titanium sponge on the bottom of the electrode block press mold, insert the mold (1) into the press mold, and adjust the bottom scale (4) and the upper scale (2) to center the mold in all directions.

[0022] (2) Open the cover plate (3), pour the alloy material into the mold (1), and then turn over the cover plate (3) to close the mold (1). At this time, a gap is formed around the mold (1) and the press mold, and then 1 / 3 of the total amount of sponge titanium is added to the surrounding gap area.

[0023] (3) After completing the above operations, 1 / 3 of the titanium sponge remains. Take out the mold (1) and pour the remaining titanium sponge into it so that the remaining titanium sponge is spread evenly on the top layer.

[0024] (4) After the loading is completed, the pressure is applied to press the electrode block. Due to the force, the sponge titanium distributed around the alloy material begins to deform, and the particles gradually adhere to each other. The boundaries of the alloy material and the sponge titanium are integrated with each other. Under the pressure, the gaps inside the alloy material gradually shrink, and it changes from loose to dense. The entire electrode block, the internal alloy material is wrapped by the compact and dense sponge titanium, and the sponge titanium around it changes from the initial particles to a whole that is bonded to each other.

[0025] (5) After the pressing is completed, the outer periphery of the obtained electrode block is dense titanium sponge, and the alloy material is embedded inside.
