Description

Technical Field

[0001] This invention relates to the field of self-consuming equipment connection devices, specifically to a connection device for a dummy electrode and a self-consuming furnace lifting rod, and its usage method. Background Technology

[0002] In recent years, with the rapid development of aerospace and defense equipment, traditional materials and manufacturing methods are increasingly unable to meet current technological requirements. The new generation of spacecraft demands farther and faster flight, requiring materials with lower density to minimize the mass of the spacecraft while maintaining the original fuel weight. Simultaneously, faster flight intensifies aerodynamic heating, necessitating materials with higher heat resistance. Ti-Al alloys possess both of these characteristics. However, because titanium alloys readily react with the crucible during melting, they are unsuitable for induction melting. Currently, Ti-Al alloy melting primarily employs vacuum arc remelting.

[0003] Due to the unique properties of Ti-Al alloys, before using the consumable alloy melting method, pure titanium, pure aluminum, and other raw materials need to be uniformly mixed together. These raw materials are then pressed into rod shapes using a press in a mold. This process primarily relies on the plastic deformation of pure aluminum and pure titanium, resulting in relatively low strength. The electrode rods are damaged during subsequent transportation and welding, and their strength further decreases after multiple electrode rods are welded together.

[0004] The existing connection between the dummy electrode and the self-consuming furnace lifting rod is made by using elastic steel balls. This method requires a large impact force to achieve a good connection effect. However, due to the large impact force, it will damage the already weak pressing electrode rod, causing the electrode rod to break and resulting in material waste.

[0005] Therefore, this application proposes a threaded connection method to achieve a stable connection between the dummy electrode and the self-consuming furnace lifting rod, and to reduce the impact force during connection, thereby reducing damage to the lifting rod and electrode rod. Summary of the Invention

[0006] The present invention aims to provide a connection device and a method for using a dummy electrode and a self-consuming furnace lifting rod, so as to reduce the impact force when the dummy electrode is connected to the self-consuming furnace lifting rod and reduce the damage to the self-consuming furnace lifting rod and the electrode rod.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A connection device for a dummy electrode and a self-consuming furnace lifting rod includes a self-consuming furnace lifting rod, a transition connecting rod, and a dummy electrode, wherein the transition connecting rod is threadedly connected between the self-consuming furnace lifting rod and the dummy electrode.

[0009] Furthermore, there are multiple transition connecting rods, and adjacent transition connecting rods are connected by a threaded connection.

[0010] Furthermore, the number of transition connecting rods is two.

[0011] Furthermore, the dummy electrode is fixedly connected to a transition electrode, and the transition electrode is fixedly connected to a consumable electrode rod.

[0012] Furthermore, the axes of the self-consuming furnace lifting rod, the transition connecting rod, the dummy electrode, the transition electrode, and the self-consuming electrode rod are all coaxial.

[0013] A method for using a device for connecting a dummy electrode to a self-consuming furnace lifting rod includes the following steps:

[0014] S1. Use a press to press multiple consumable electrode rods, weld the multiple consumable electrode rods together to form consumable electrode rod segments, and then weld the consumable electrode rod segments onto the transition electrode.

[0015] S2. The transition electrode is then welded onto the dummy electrode.

[0016] S3. Multiple transition connecting rods are connected by threads to form a transition connecting section, which is then threaded between the self-consuming furnace lifting rod and the dummy electrode.

[0017] Working principle and beneficial effects of the present invention:

[0018] This solution provides a device for effectively connecting a dummy electrode and a self-consuming furnace lifting rod. The device includes a threaded transition connecting rod between the lifting rod and the dummy electrode. This connection effectively avoids the material waste caused by electrode rod damage or breakage due to collisions during the connection process using elastic steel balls, as is common in existing technologies. Furthermore, the multiple transition connecting rods between the dummy electrode and the lifting rod minimize damage to the lifting rod threads during the connection process. The transition connecting rods can be easily removed for convenient maintenance.

[0019] Furthermore, S2 and S3 are welded using argon arc welding, and pure titanium is used as a filler. Attached Figure Description

[0025] The following detailed description illustrates the specific implementation method:

[0026] The reference numerals in the accompanying drawings include: 1. self-consumable furnace lifting rod; 2. transition connecting rod; 3. dummy electrode; 4. transition electrode; 5. self-consumable electrode rod.

[0027] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0028] Reference Figure 1 In the existing technology, the connection between the dummy electrode 3 and the self-consuming furnace lifting rod 1 is achieved by using elastic steel balls. This method requires a large force to achieve a good connection effect during docking. However, due to the large impact force, it will damage the already weak pressing electrode rod, causing the electrode rod to break and resulting in material waste.

[0029] Example: A connection device between a dummy electrode 3 and a self-consuming furnace lifting rod 1, refer to Figures 2-5 It includes a self-consuming furnace lifting rod 1, two transition connecting rods 2, and a dummy electrode 3.

[0030] Before self-consumable electrode production, pure titanium, pure aluminum, and other raw materials are uniformly mixed and pressed into self-consumable electrode rods 5 with a diameter of 30 mm and a length of 300 mm using a press. Two electrode rods are welded together using argon arc welding. The welded electrode rods are then welded onto transition electrode 4, and transition electrode 4 is then welded onto dummy electrode 3. Pure titanium is used as the filler material during welding.

[0031] Two transition connecting rods 2 are connected to each other by a threaded connection, and then the whole is threadedly connected between the self-consuming furnace lifting rod 1 and the dummy electrode 3.

[0032] This solution provides a device for effectively connecting the dummy electrode 3 and the consumable furnace lifting rod 1. The dummy electrode 3 is connected to the consumable furnace lifting rod 1 and the dummy electrode 3 by a threaded transition connecting rod 2. Because the existing technology only relies on elastic steel balls to directly connect the dummy electrode 3 and the consumable furnace lifting rod 1, this connection method makes it easy for the dummy electrode 3 and the consumable furnace lifting rod 1 to collide. The impact force generated by the collision is large, and a large force is required during installation. Therefore, it is easy to damage the consumable electrode rod 5, which is not strong enough, causing the consumable electrode rod 5 to break and resulting in material waste.

[0033] This solution, through the indirect connection of transition connecting rod 2 and threaded connection, effectively avoids collisions and minimizes the impact force during docking, thus preventing damage to the consumable electrode rod 5 and avoids breakage, which would result in material waste. Furthermore, two transition connecting rods 2 are installed between the dummy electrode 3 and the consumable furnace lifting rod 1, which can largely prevent damage to the threads of the lifting rod 1 during docking. The transition connecting rods 2 can be removed at any time for convenient maintenance.

[0034] For those skilled in the art, numerous modifications and improvements can be made without departing from the inventive concept of this invention. These modifications and improvements should also be considered within the scope of protection of this invention, and will not affect the effectiveness of the invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
