Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a friction welding device for an anode guide rod and a steel claw in an aluminum electrolysis cell. Background Technology

[0002] The aluminum electrolytic cell is the core equipment in aluminum electrolysis production. The anode conductive device, as a key component, plays a crucial role in transmitting the large electrolytic current and supporting the anode carbon block. The anode guide rod and steel claw are the core connecting parts of the anode conductive device, and their reliable connection directly affects the conductivity efficiency, equipment operational stability, and production continuity in aluminum electrolysis. Therefore, a specialized process is required to achieve an effective welding connection between the two.

[0003] Friction welding does not involve metal melting, which can effectively avoid the formation of brittle intermetallic compounds when joining dissimilar metals such as aluminum and steel. Furthermore, the welding heat-affected zone is small, which can improve the electrical conductivity while ensuring the mechanical strength of the joint. It meets the connection process requirements of the anode guide rod and the steel claw, making it the preferred technical solution for achieving high-quality welding between the two. It is also suitable for the complex working conditions of aluminum electrolysis production, such as high temperature, high current, and alternating load.

[0004] During friction welding of the anode guide rod and steel claw, the welding interface generates heat due to intense friction, creating moving thermal stress. During welding, the guide rod and steel claw are clamped and fixed by tooling, resulting in a rigid constraint that prevents the release of thermal stress. After welding is completed and the clamping is released, the constraint on the formed part disappears, and the residual thermal stress at the welded area is rapidly released. This leads to deformation of the welded assembly, ultimately causing a decrease in the dimensional accuracy and mechanical properties of the formed part. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the residual stress is released rapidly after the clamping of the molded part is released, which causes the molded part to deform and the dimensional accuracy and performance of the molded part to decline. To this end, we propose a friction welding device for the anode guide rod and steel claw of aluminum electrolysis cell.

[0006] To achieve the above objectives, this application adopts the following technical solution: a friction welding device for an anode guide rod and a steel claw in an aluminum electrolysis cell, comprising a support platform, wherein a rotating spindle clamping unit for clamping and rotating the guide rod and a fixed seat for clamping the steel claw are fixedly installed on the top surface of the support platform; the fixed seat has a connection port for inserting the guide rod into contact with the steel claw on the side facing the output end of the rotating spindle clamping unit; and two connecting blocks symmetrical about the connection port are fixedly installed on the side of the fixed seat facing the rotating spindle clamping unit.

Clamping blocks for clamping guide rods are movably installed on opposite sides of the two clamping seats. Semi-cylindrical grooves are opened on the clamping seats and clamping blocks for fitting the guide rod inside. Spray heads are provided on opposite sides of the two clamping seats. The spray heads are movably installed on the clamping seats through universal joints. The clamping seats are hollow structures. A traction component is provided on the inner side of the clamping seats for the clamping blocks to control the spray heads to change direction.

[0008] Preferably, a flow chamber is provided between the inner wall and the outer side of the fixing seat, and a flexible hose connected to the flow chamber is fixedly connected to both sides of the fixing seat. The air outlet of the flexible hose is fixedly installed to two clamping seats and connected to their inner cavities.

[0009] Preferably, two horizontally opposite air storage cylinders are provided on one side of the fixed base. A fixed plate is fixedly installed on both air storage cylinders. The two fixed plates are respectively fixedly installed on two support blocks. Connecting rods that penetrate into the inner cavity are movably sleeved on opposite sides of the two air storage cylinders. A piston plate is fixedly connected to one end of each connecting rod inside the air storage cylinder. Connecting pipes are fixedly connected to the opposite sides of the top of the side walls of the two air storage cylinders. The connecting pipes are fixedly installed on the fixed base and communicate with the flow chamber. A solenoid valve is installed on the connecting pipe. Vertical plates facing the two ends of the air storage cylinders are fixedly installed on both sides of the top surface of the support platform. The ends of the two connecting rods outside the air storage cylinders are respectively connected to the two vertical plates. An air inlet pipe is fixedly connected to the end of each air storage cylinder away from the connecting rod. A one-way valve is installed on the air inlet pipe.

[0010] Preferably, the opposing surfaces of the two vertical plates are fixedly connected to I-shaped slide rails, and the ends of the two connecting rods located outside the gas storage cylinder are provided with I-shaped movable grooves. The two connecting rods are slidably connected to the two I-shaped slide rails through the I-shaped movable grooves.

[0011] Preferably, the clamping seat has an air guide hood on the side facing the fixed seat, and the two air guide hoods are fitted together to form a trumpet shape.

[0012] Preferably, the traction assembly includes a track plate disposed in the inner cavity of the clamping seat, the track plate having an arc-shaped track groove, a sliding shaft fixedly connected to the bottom of the outer wall of the nozzle near the air inlet end, and a traction rod hinged to one end of the track plate near the clamping block, one end of the traction rod being hinged to the side wall of the clamping block for causing the clamping block to traction the track plate to move linearly.

[0015] Preferably, a second hydraulic push rod is fixedly connected to both sides of the inner wall of the fixed base, and a clamping block is fixedly connected to the telescopic end of each of the two second hydraulic push rods for clamping and fixing the steel claw.

[0016] The technical effects and advantages of this invention are as follows: In this invention, the first hydraulic push rod drives two clamping seats to move towards each other, so that the two clamping blocks clamp and fix the guide rod. After the rotating spindle clamping unit releases the guide rod, the clamping action of the clamping blocks can delay the release rate of thermal stress at the welding part of the molded part, reduce the deformation caused by thermal stress, and keep the deformation within the standard allowable range, thus ensuring the dimensional accuracy and mechanical properties of the molded part.

[0017] In this invention, the nozzle first sprays high-pressure air directly onto the guide rod to achieve heat dissipation. Then, the slight deformation of the guide rod pushes the clamping block into the clamping seat. The clamping block pulls the track plate to move horizontally, causing the sliding shaft to deflect along the trajectory of the arc-shaped track groove. This rotates the nozzle so that the air outlet is tilted towards the welding position of the guide rod and the steel claw, allowing the high-pressure air to be precisely sprayed directly onto the welding part. This not only improves the heat dissipation effect of the welding part, but also avoids the adverse problems caused by the direct spraying of high-pressure air onto the welding point in the early stage of welding.

Detailed Implementation

[0020] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0021] Reference Figure 1-8As shown, the present invention provides a technical solution: a friction welding device for an anode guide rod and a steel claw in an aluminum electrolysis cell, comprising a support platform 1, a rotating spindle clamping unit 2 for clamping and rotating the guide rod and a fixed seat 3 for clamping the steel claw, the rotating spindle clamping unit 2 driving the guide rod to rotate, causing the guide rod to friction weld with the steel claw, and two second hydraulic push rods 34 fixedly connected to both sides of the inner wall of the fixed seat 3, the telescopic ends of the two second hydraulic push rods 34 being fixedly connected to clamping blocks 35, after the steel claw is placed into the fixed seat 3, the second hydraulic push rods 34. Push the clamping block 35 to move, so that the two clamping blocks 35 clamp and fix the steel claw. This is used to clamp and fix the steel claw. The fixing base 3 has a connection port on the side facing the output end of the rotating spindle clamping unit 2 for the guide rod to be inserted and contact the steel claw. Two connecting blocks 4 symmetrical about the connection port are fixedly installed on the side of the fixing base 3 facing the rotating spindle clamping unit 2. Two first hydraulic push rods 5 are fixedly connected to each other on opposite sides between the two connecting blocks 4. The telescopic ends of the two first hydraulic push rods 5 are fixedly connected to clamping seats 6. The first hydraulic push rods 5 push the two clamping seats. The two clamping seats 6 move towards each other until they are in contact, so that the guide rod is clamped inside by the circular groove. Clamping blocks 7 for clamping the guide rod are movably installed on the opposite sides of the two clamping seats 6. The clamping blocks 7 move with the clamping seats 6, clamping the guide rod. Both the clamping seats 6 and the clamping blocks 7 have semi-cylindrical grooves for fitting the guide rod inside. The two semi-cylindrical grooves combine to form a circular groove. Each of the two clamping seats 6 has a nozzle 8 on its opposite side. A rubber elastic pad 33 is fixedly installed on one side of the inner wall of the clamping seat 6. One side of the rubber elastic pad 33 is fixedly installed to the clamping block 7, which clamps the guide rod. When the guide rod deforms due to stress, it will push the clamping block 7 into the clamping seat 6. After being pushed, the clamping block 7 will squeeze the rubber elastic pad 33, thereby absorbing a certain amount of stress. The nozzle 8 is movably mounted on the clamping seat 6 through the universal joint. The clamping seat 6 is a hollow structure. High-pressure air is input into the clamping seat 6. The high-pressure air is discharged through the nozzle 8 and sprayed onto the guide rod. The clamping seat 6 is equipped with a traction component inside, which is used to control the nozzle 8 to change its orientation so that the nozzle 8 can rotate and tilt after being clamped to spray high-pressure air towards the welding point between the guide rod and the steel claw.

[0022] To control the movement of the fixed base 3, a first slide rail 9 is fixedly connected to the top of the support platform 1. A first electric slider 10 is slidably connected to the first slide rail 9. A support plate 11 is fixedly connected to the top of the first electric slider 10. The first electric slider 10 slides on the first slide rail 9, which can remove the welded molded part from the front of the rotating spindle clamping unit 2. A second slide rail 12 is fixedly connected to both sides of the top surface of the support plate 11. A second electric slider 13 is slidably connected to the second slide rail 12. A support block 14 is fixedly connected to the top surface of the second electric slider 13. The top surface of the support block 14 is fixedly connected to the bottom surface of the fixed base 3. The second electric slider 12 slides on the second slide rail 13, which drives the fixed base 3 to move and pull the guide rod end in the molded part out of the clamping end of the rotating spindle clamping unit 2.

[0023] To supply air to the clamping seat 6, a flow chamber is provided between the inner wall and the outside of the fixed seat 3. Flexible hoses 15, connected to the flow chamber, are fixedly connected to both sides of the fixed seat 3. The air outlets of the hoses 15 are fixedly installed to the two clamping seats 6 and connected to their inner cavities. Air enters the flow chamber within the fixed seat 3 and is then supplied to the two fixed seats 3 through the two hoses 15. Two horizontally opposing air storage cylinders 16 are provided on one side of the fixed seat 3, and a fixing plate 17 is fixedly installed on both air storage cylinders 16. Two fixing plates 17 are respectively fixedly installed on two support blocks 14. Connecting rods 18, penetrating into the inner cavity, are movably sleeved on opposite sides of the two air storage cylinders 16. Piston plates 19 are fixedly connected to one end of each connecting rod 18 inside the air storage cylinder 16. When the support plate 11 moves, it drives the air storage cylinders 16 to move synchronously. When the support plate 11 moves to one side, it compresses the air inside one side of the air storage cylinder 16, forming high-pressure air. Connecting pipes 2 are fixedly connected to the opposite sides of the top of the side walls of the two air storage cylinders 16. 0. Connecting pipe 20 is fixedly installed on fixed base 3 and connected to the flow chamber. A solenoid valve 21 is installed on connecting pipe 20. When fixed base 3 moves to the designated position, solenoid valve 21 opens, allowing high-pressure air in air storage cylinder 16 to enter the flow chamber on fixed base 3 through connecting pipe 20. Vertical plates 22 are fixedly installed on both sides of the top surface of support platform 1, facing the two ends of air storage cylinder 16 respectively. The ends of two connecting rods 18 located outside air storage cylinder 16 are connected to the two vertical plates 22 respectively. The two air storage cylinders 16 are far from each other. An air inlet pipe 23 is fixedly connected to one end of the connecting rod 18. A one-way valve 24 is installed on the air inlet pipe 23. When the air in one air storage cylinder 16 is being compressed, the one-way valve 24 on the other air storage cylinder 16 opens. At the same time, due to the movement, the air storage cylinder 16 draws outside air into its inner cavity. Therefore, when the first electric slider 10 moves to one side, the air in one air storage cylinder 16 is compressed. Conversely, when the first electric slider 10 moves to the other side, the air in the other air storage cylinder 16 is compressed.

[0024] In order to ensure that the connecting rod 18 can move linearly along the sliding trajectory of the second electric slider 13 without falling off the vertical plate 22, I-shaped slide rails 25 are fixedly connected to the separating surfaces of the two vertical plates 22. I-shaped movable grooves are opened at the ends of the two connecting rods 18 located outside the gas storage cylinder 16. The two connecting rods 18 are slidably connected to the two I-shaped slide rails 25 through the I-shaped movable grooves. The connecting rod 18 can adapt to the sliding trajectory of the second electric slider 13 and will not fall off the vertical plate 22.

[0025] To increase the number of air guide hoods 26 on the side of the clamping seat 6 facing the fixed seat 3, the two air guide hoods 26 are fitted together to form a funnel shape. The frustum shape has a large opening away from the air guide hood 26. The air injected into the circular groove formed by the two clamping seats 6 will be discharged from the port of the circular groove. The cross-sectional area of ​​the funnel shape formed by the combination of the two air guide hoods 26 gradually increases, which can make the discharged air more uniform, optimize the diffusion and impact characteristics of the airflow, improve heat dissipation efficiency, expand the effective heat dissipation area, and reduce airflow turbulence loss.

[0026] To enable the clamping block 7 to pull the nozzle 8 to tilt and change its orientation, the traction assembly includes a track plate 27 disposed within the cavity of the clamping seat 6. The track plate 27 has an arc-shaped track groove 28. A sliding groove 31 is fixedly connected to the bottom of the inner side of the clamping seat 6. Several sliding rods 32 are fixedly connected to the bottom of the track plate 27. The sliding rods 32 are slidably connected within the sliding groove 31, which faces the clamping block 7. Therefore, when the sliding rods 32 slide within the sliding groove 31, they can only move horizontally towards or away from the clamping block 7. A sliding shaft 29 is fixedly connected to the bottom of the outer wall of the nozzle 8 near the air inlet end. When… When the track plate 27 moves horizontally, it can pull the sliding shaft 29 to move through the arc-shaped track groove 28. The sliding shaft 29 deflects along the trajectory of the arc-shaped track groove 28, causing the nozzle 8 to rotate in the universal head. This changes the nozzle 8 so that the air outlet end is tilted towards the welding position of the guide rod and the steel claw. A traction rod 30 is hinged to one end of the track plate 27 near the clamping block 7. One end of the traction rod 30 is hinged to the side wall of the clamping block 7, which is used to make the clamping block 7 pull the track plate 27 to move linearly. When the clamping block 7 moves towards the inside of the clamping seat 6, the traction rod 30 pulls the track plate 27 to move.

[0027] Working principle: After the guide rod and steel claw are welded, the first hydraulic push rod 5 drives the two clamping seats 6 to move towards each other. The clamping seats 6 simultaneously drive the clamping blocks 7 to move, so that the two clamping blocks 7 clamp and fix the guide rod. After the rotating spindle clamping unit 2 releases the clamping of the guide rod, the clamping action of the clamping blocks 7 can delay the release rate of thermal stress at the welded part of the molded part, reduce the deformation caused by thermal stress, and keep the deformation within the standard allowable range, thus ensuring the dimensional accuracy and mechanical properties of the molded part. At this time, the solenoid valve 21 on the corresponding connecting pipe 20 opens, and the high-pressure air formed in the air storage cylinder 16 is discharged. The high-pressure air enters the flow cavity of the fixed seat 3 through the connecting pipe 20, and is then transported to the inner cavity of the two clamping seats 6 through the hose 15, and finally sprayed outward by the nozzle 8. In the initial state, the nozzle 8 faces the guide rod, and high-pressure air is directly sprayed onto the guide rod to dissipate heat. The guide rod undergoes slight deformation due to the heat effect near the welding area. This deformation pushes the clamping block 7 into the clamping seat 6. As the clamping block 7 moves into the clamping seat 6, the traction rod 30 pulls the track plate 27 to move horizontally. During the horizontal displacement of the track plate 27, the sliding shaft 29 deflects along the trajectory of the arc-shaped track groove 28, causing the nozzle 8 to rotate at the universal joint. This tilts the air outlet of the nozzle 8 towards the welding position of the guide rod and the steel claw, allowing the high-pressure air to be precisely sprayed directly onto the welding area. This not only improves the heat dissipation effect of the welding area but also avoids the adverse problems caused by the direct spraying of high-pressure air onto the welding point in the early stages of welding.

[0028] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
