Description

Technical Field

[0001] This application relates to the field of die casting technology for titanium and titanium alloy smelting electrode blocks, and in particular to a die casting punch for titanium and titanium alloy smelting electrode blocks. Background Technology

[0002] Titanium, due to its superior strength and corrosion resistance compared to other conventional metals, is widely used in aerospace, chemical, medical, and marine engineering fields, either as a single raw material or in mixtures with other metals, to produce titanium and titanium alloy products. Currently, the preparation of titanium and titanium alloy products mainly involves mechanically die-casting sponge titanium or mixtures with other metal raw materials into block structures, which are then used as electrode blocks in a vacuum melting furnace to form ingots. These ingots can then be processed into usable product forms such as bars, wires, and tubes through various machining methods.

[0003] As per the instruction manual Figure 1-2 The process involves mixing sponge titanium or other raw materials using a die-casting machine and then pressing them. The specific pressing operation is as follows: Figure 2 As shown, the raw materials are quantitatively filled into the die-casting tank, and then the die-casting punch is driven into the die-casting tank by hydraulic force to compress the loose raw materials into a block structure. Then, multiple die-casting blocks are welded together (welding can increase the height of the entire electrode block to match the height of the crucible in the melting furnace, increase the single melting amount, and reduce energy consumption) and placed in the melting furnace to be used as electrode blocks to be melted into ingots.

[0004] Currently, when die-casting individual electrode blocks, such as Figure 4 As shown, due to the embedding gap between the die-casting punch and the inner wall of the die-casting tank, after die-casting, the raw material at the side of the electrode block is squeezed and filled into this embedding gap, thus forming die-casting burrs on the side of the electrode block after die-casting. Figure 5 As shown, during the welding operation of adjacent electrode blocks, the die-cast burrs prevent adjacent electrode blocks from touching and making stable welding impossible. When the welded electrode blocks are hoisted into the crucible, there is also a risk of them falling off. Furthermore, when used as electrodes during the melting process, they cannot conduct electricity stably. Therefore, currently, after a single electrode block is die-cast, workers need to knock the die-cast burrs down to make them lower than the die-cast surface so as not to affect welding. This manual operation increases the forming process of the electrode block. At the same time, the die-cast burrs still have metal strength, and long-term continuous manual knocking places a great physical burden on workers and increases production costs. Utility Model Content

[0005] To address the aforementioned problems, this application aims to provide a die-casting punch for titanium and titanium alloy smelting electrode blocks, which can ensure that the die-casting burrs during the electrode block die-casting process are lower than the electrode block surface, thus not obstructing the welding of adjacent electrode blocks after they are attached, improving the welding tightness of the electrode blocks, and solving the current manual subsequent hammering operation, thereby improving production efficiency and reducing costs.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a die-casting punch for titanium and titanium alloy melting electrode blocks, which is fitted with a die-casting tank with an open top, wherein the die-casting tank contains die-casting raw materials, characterized in that: a die-casting structure is provided on the bottom surface of the die-casting punch, wherein after the die-casting raw materials are formed into a block-shaped electrode block, the side of the electrode block is lower than its top surface.

[0007] Furthermore, the die-casting structure is a groove opened on the bottom surface of the die-casting punch, the bottom surface of the groove is the die-casting surface, and a die-casting side is formed between the groove and the side of the die-casting punch.

[0008] Preferably, a die-casting plate is detachably provided on the die-casting side of the bottom surface of the die-casting punch. The side of the die-casting plate extends downward in a circumferential direction to a die-casting ring plate that contacts the side of the die-cast electrode block, and the side of the electrode block is located at the middle position of the die-casting ring plate.

[0009] Preferably, the bottom surface of the die-cast ring plate is provided with an inclined structure that connects with the outer wall.

[0010] The beneficial effects of this application are as follows: This application provides a die-casting structure on the die-casting punch. After the die-casting raw material is formed into a block-shaped electrode block, the side of the electrode block is lower than its top surface. Then, when the raw material entering the gap between the die-casting punch and the die-casting tank forms a die-casting burr, the die-casting burr is lower than the surface of the electrode block, so as not to obstruct the welding of adjacent electrode blocks after they are attached, thereby improving the welding tightness of the electrode blocks. At the same time, it solves the current problem of manual subsequent hammering operation, improves production efficiency and reduces costs.

[0011] The die-casting plate can be used to re-die-cast the die-casting burrs, making their height uniformly lower than the surface of the electrode block. At the same time, the die-casting burrs are further squeezed to avoid falling off during subsequent transfer and welding processes, thus preventing material waste. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] See attached document Figures 1-15The diagram illustrates a die-casting punch for titanium and titanium alloy smelting electrode blocks. The punch 1 is fitted with a die-casting tank 2 with an open top. The tank 2 contains die-casting raw material, which can be sponge titanium or a mixture of other metals. After a predetermined amount of raw material is filled into the tank 2, hydraulic force drives the punch 1 downwards into the tank 2 to extrude the raw material into a block shape. One vertical side of the tank 2 is openable. After opening, the tank 2 moves backward (the opening and moving structures are not shown in the diagram), allowing the formed electrode block to detach from its inner wall. After die-casting multiple electrode blocks, welding is performed on them.

[0030] To address the problem of die-casting burrs formed when raw material enters the gap between the die-casting punch 1 and the die-casting tank 2 during the current die-casting process of electrode blocks, which affects subsequent welding, this application provides a die-casting structure on the bottom surface of the die-casting punch 1. After the die-casting raw material is formed into a block-shaped electrode block, the side of the electrode block is lower than its top surface. That is, when the die-casting punch 1 contacts and extrudes the raw material, a forming surface can be formed on the surface of the electrode block through the die-casting structure. At the same time, the side of the electrode block is lower than this forming surface. Consequently, when the raw material entering the gap forms die-casting burrs, the lower side also prevents the die-casting burrs from obstructing the welding of adjacent electrode blocks, thus improving the welding tightness of the electrode blocks. This also eliminates the need for manual subsequent hammering operations, improving production efficiency and reducing costs.

[0031] Specifically, such as Figure 6-9 As shown, the die-casting structure consists of a groove 1a formed on the bottom surface of the die-casting punch 1. The bottom surface of the groove 1a is the die-casting surface a1, and a die-casting side a2 is formed between the groove 1a and the side of the die-casting punch 1. The die-casting operation of the die-casting punch 1 is as follows: Figure 8 As shown, when the die-casting punch 1 enters the die-casting tank 2 and squeezes the raw material downward, most of the raw material enters the groove 1a and forms the surface of the electrode block through the die-casting surface a1; while the die-casting side a2 is squeezed downward to form the side of the electrode block. This side is lower than the surface of the electrode block and forms a boss structure on the surface of the electrode block. Therefore, when the raw material at the side enters the embedding gap, a die-casting burr is formed on the lower side and is lower than the upper surface of the electrode block. Therefore, the die-casting burr of the electrode block formed by this die-casting structure does not affect the welding operation of adjacent electrode blocks and also solves the problem of the manual hammering process.

[0032] The die-casting burrs formed during the aforementioned die-casting process are irregular in shape, and thus may be higher or lower than the die-casting top surface. When the die-casting burrs are higher than the die-casting top surface, they still obstruct the welding of adjacent electrode blocks to a certain extent, requiring manual hammering to remove the excessively high die-casting surface. Therefore, to further solve this problem, such as... Figure 12-14 As shown, a die-casting plate 3 is detachably mounted on the die-casting side a2 of the bottom surface of the die-casting punch 1. A die-casting ring plate 31 extends circumferentially downward from the side of the die-casting plate 3, contacting the side of the die-cast electrode block. The side of the electrode block is located at the center of the die-casting ring plate 31. The operation process is as follows: Figure 14 As shown, after the die-casting punch 1 first die-casts the raw material into a block structure, one side wall of the die-casting tank 2 opens and moves backward to detach from the electrode block. Then, the die-casting plate 3 is assembled onto the die-casting side a2 at the bottom of the die-casting punch 1. Next, the die-casting punch moves downward again, so that the bottom surface of the die-casting ring plate 31 contacts the die-casting burr (the width of the bottom surface of the die-casting ring plate 31 allows the die-casting burr to be located in the middle position, effectively contacting the die-casting burr during die-casting). The die-casting burr is then die-cast downward again, making it lower than the top surface of the electrode block, thereby solving the problem of contact obstruction between adjacent electrode blocks during welding. At the same time, further die-casting of the die-casting burr also avoids the problem of thin die-casting burrs easily falling off during electrode block transfer and welding operations.

[0033] To facilitate the rapid assembly of the die-casting plate 3, the die-casting plate 3 is preferably magnetically connected to the die-casting punch 1, which allows for quick assembly. This facilitates the removal of the die-casting plate 3 from the die-casting punch 1 during raw material die-casting and enables rapid assembly when trimming die-casting burrs, thereby improving continuous operation efficiency.

[0034] To facilitate precise assembly of the die-cast plate 3 and avoid misalignment during assembly that could lead to misalignment between the die-casting ring plate 31 and the die-casting burrs, thus preventing accurate die-casting of the burrs, preferably, as follows: Figure 12 As shown, a positioning boss 32 that can be embedded into the groove 1a is also provided on the top of the die-cast plate 3. The positioning boss 32 enables the die-cast plate 3 to be accurately assembled and enables the die-casting burrs of the die-casting ring plate 31 and the electrode block to be correspondingly contacted and die-cast.

[0035] During the die-casting trimming process described above, the die-casting burrs are squeezed towards the inner and outer sides of the electrode block. The burrs squeezed inwards can "adhere" to the formed side surface, while the burrs squeezed outwards are suspended and easily break off. Therefore, to solve this problem, such as... Figure 15 As shown, a sloping structure 3a is provided on the bottom surface of the die-casting ring plate 31, which is in contact with the outer wall. During the downward die-casting process, this sloping structure contacts the outer side of the die-casting burr. When the die-casting force is applied downward, the sloping structure 3a can prevent the die-casting burr from being squeezed to the outside and breaking off. Instead, it is squeezed inward to the formed side, thus avoiding waste of raw materials.

[0036] The principle of this application is as follows: When performing die casting of a single electrode block, the raw material is filled into the die casting tank 2. Then, the die casting punch 1 enters the die casting tank 2 and squeezes the raw material downward, forming a boss on the surface of the electrode block through the groove 1a. Then, the die casting tank 2 moves and separates from the electrode block. After the die casting plate 3 is assembled at the bottom of the die casting punch 1, it is pressed down again. When pressing down, the die casting ring plate 31 contacts the die casting burr to perform die casting, so that the die casting burr is uniformly lower than the die casting top surface. After completing the die casting of multiple electrode blocks, a splicing and welding operation is performed. After welding, the electrode block is placed in the crucible of the melting furnace to be melted into an ingot.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
