Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to a rotatable anode guide rod assembly aluminum-steel direct welding tooling. Background Art

[0002] Electrolysis is one of the common chemical processing methods. Electric current is passed through the anode and cathode in the electrolytic cell to cause a reaction and obtain the desired product. In the electrolysis process, a variety of components are needed, among which the anode guide rod is one of them. Its main function is to connect the anode in the electrolytic cell to ensure the smooth progress of the electrolysis process. The material of the anode guide rod usually has good conductivity and corrosion resistance to ensure the stability and safety of the electrolysis process. The anode guide rod is generally composed of a steel claw and a guide rod, which are connected by welding. The welding process is generally carried out on welding tools.

[0003] In the prior art, the existing welding method is generally a brazing welding method, which requires a high level of proficiency for the welders and requires the processing personnel to operate close to the tooling. Due to the high temperature during welding, the processing environment is harsh and burns are prone to occur. At the same time, the existing welding tooling often requires manual clamping and fixing of steel claws, which has high labor intensity. The temperature of the anode guide rod that has just been welded is high, and it is necessary to wait for it to cool before unloading.

[0009] The cam is provided with a plurality of fixing tubes, each of which is connected with a plurality of fixing tubes, and each of which is a plurality of fixing tubes. The fixing tubes are connected with the corresponding fixing tubes in the fixing tubes, and the fixing tubes are sealed and slidably connected with a sliding column. One end of the sliding column located in the fixing groove is fixedly connected with a clamping block. The side wall of the column is provided with an annular groove, and the inner side wall of the annular groove is fixedly connected with a protrusion. The rotating seat is provided with a plurality of through holes, and the through holes connect the corresponding the annular groove.

[0012] Furthermore, a protective cover is fixedly connected to the upper surface of the tooling seat.

[0013] The present invention has the following advantages:

[0014] 1. Welding is done by aluminothermic welding. The molten metal is poured into the mold to complete the welding. Compared with traditional brazing and other methods, it does not require operators to have more skilled welding skills, thus ensuring the welding quality;

[0015] 2. The servo motor drives the active pulley to rotate for one circle, so that the driven pulley rotates. The driven pulley rotates and then pulls the slider through the push-pull block. At the same time, the slider drives the pump block to slide, and the hydraulic oil makes the follower block move synchronously, so that the two half molds move relative to each other and complete the mold closing. When the servo motor continues to rotate for one circle, the push-pull block can push the slider to complete the separation of the two half molds. There is no need to open and close the mold manually, and there is no need to operate near the main welding position, which ensures an excellent working environment, avoids burns, and improves safety;

[0016] 3. When the two half molds are closed, the push-pull block will continue to pull the trigger plate until the first spring force is overcome, so that the trigger plate contacts the button and is pressed, so that the solenoid valve opens and welding begins. That is, welding begins only when the pressure after the two half molds are closed reaches a certain level, thereby ensuring the closing pressure, avoiding gap leakage, and improving welding quality.

[0017] 4. During welding, place the steel claw in the placement groove. As the rotating seat rotates, the steel claw is rotated to the bottom of the discharge pipe. At this time, the guide wheel and the convex block are abutted, so that the driving block slides into the through hole, so that the four slide columns slide synchronously, driving the four clamping blocks to slide synchronously. While clamping the steel claw, it is positioned so that the steel claw is aligned with the guide block, so that manual clamping and positioning are not required, which greatly reduces the labor intensity, avoids the error of manual operation, and ensures the accuracy of welding;

[0018] 5. Place the steel claw in the placement slot. With the rotation of the rotating seat, the material loading and automatic positioning clamping can be completed, making the tooling more automated. After the welding of an anode guide rod is completed, the rotating seat rotates it away from the discharge pipe, and the next steel claw to be welded is rotated to the bottom of the discharge pipe. During the cooling process of the previous welding, the welding of the next anode guide rod can continue, thereby realizing continuous welding processing and greatly improving processing efficiency.

[0019] 6. The clamping and positioning mechanism can clamp and fix steel claws of different sizes, so that the tooling can be used for the processing of steel claws of different sizes, making the tooling more widely applicable;

[0020] 7. During the clamping and positioning process, as the driving block slides, the clamping block and the steel claw clamp it. When the clamping is completed, as the clamping force increases, the pressure of the internal hydraulic oil gradually increases until it increases to the opening value of the pressure relief valve, and the hydraulic oil will be pressed into the cavity, thereby ensuring that each time the steel claw is clamped, a stable clamping force can be guaranteed, thereby ensuring the stability of the steel claw after clamping, and thus ensuring the welding quality.

DETAILED DESCRIPTION

[0030] Reference Figure 1-8 A rotatable anode guide rod assembly aluminum-steel direct welding tool, comprising a tool seat 1, a column 2 is fixedly connected to the upper surface of the tool seat 1, and an aluminum heat tank 3 is provided in the column 2. Aluminum heat reaction is carried out in the aluminum heat tank 3 to produce molten metal for welding. The column 2 is rotatably connected to a rotating seat 4 through a bearing, and a plurality of placement slots 49 are provided on the rotating seat 4. An electric push rod 50 is fixedly connected to the side wall of the column 2, and the output shaft of the electric push rod 50 is fixedly connected to a guide block 28. A servo motor 5 is fixedly connected to the upper surface of the tool seat 1 through a bracket. The servo motor 5 can accurately control its forward and reverse rotation and its rotation angle. It is a prior art. The output shaft of the servo motor 5 is fixedly connected to the side wall of the column 2. A driving shaft 6 is fixedly connected, and the driving shaft 6 is rotatably connected to a driving pulley 7 and a driving gear 26 through a one-way bearing. The one-way bearing is arranged so that when the driving shaft 6 rotates clockwise, it can drive the driving pulley 7 to rotate without driving the driving gear 26, and when it rotates counterclockwise, it can drive the driving gear 26 to rotate without driving the driving pulley 7. Therefore, a servo motor 5 can simultaneously control mold closing and loading and unloading. Welding is performed by aluminum thermite welding, and welding can be completed by pouring molten metal into the mold. Compared with traditional brazing and other methods, it does not require operators to have more skilled welding skills, thereby ensuring welding quality.

[0031] A welding mechanism is provided on the tooling seat 1, and the welding mechanism includes a sliding groove 10, which is provided on the tooling seat 1, and the tooling seat 1 is slidably connected to a slider 11 through the sliding groove 10, and a liquid groove 12 is provided on the inner wall of the sliding groove 10, and a pump block 13 is sealed and slidably connected in the liquid groove 12, and a connecting rod 14 is fixedly connected between the pump block 13 and the slider 11, and a groove 15 is provided on the column 2, and the column 2 is sealed and slidably connected to a follower block 16 through the groove 15, and a connecting pipe 17 is fixedly connected to the column 2 and the tooling seat 1 through the groove 15, and the connecting pipe 17 connects the liquid groove 12 with the groove 15, and the side wall of the slider 11 on the opposite side of the follower block 16 is fixedly connected to a heat insulating block 18, and the side wall of the two heat insulating blocks 18 on the opposite side is fixedly connected to a half mold 19, and the two half molds 19 (such as Figure 1The liquid tank 12 and the groove 15 are filled with hydraulic oil. The heat insulating block 18 can isolate the high temperature generated during the welding of the half mold 19 to prevent the high temperature from damaging the slider 11 and the follower block 16. The contact area between the follower block 16 and the hydraulic oil is consistent with the contact area between the pump block 13 and the hydraulic oil, thereby ensuring that the movement of the follower block 16 and the slider 11 is consistent, and further ensuring that after the two half molds 19 are closed, they can be located directly below the guide block 28. The welding mechanism also includes a trigger plate 20, the cross section of the trigger plate 20 is L-shaped, the trigger plate 20 is slidably connected with the slider 11, the upper surface of the tooling seat 1 is rotatably connected with a driven shaft 8 through a bearing, the driven shaft 8 is fixedly connected with a driven pulley 9, the driven pulley 9 and the driving pulley 7 are jointly matched with a synchronous belt 25, the side walls of the driving pulley 7 and the driven pulley 9 are provided with teeth, and the inner wall of the synchronous belt 25 is also provided with teeth, so that the driving pulley 7, the driven pulley 9 and the synchronous belt 25 are meshing transmission, ensuring smooth transmission, and the driven pulley 9 and the upper surface of the trigger plate 20 are fixedly connected with a fixed The two fixed columns 21 are connected to the push-pull block 22 through the bearing, and a plurality of first springs 23 are fixedly connected between the trigger plate 20 and the slider 11. The stiffness coefficient of the first spring 23 is relatively large. During the movement of the trigger plate 20, when the two half molds 19 are not in contact, the first spring 23 is not compressed. After the two half molds 19 are in contact and abut against each other, the first spring 23 will be compressed as the pressure increases. The side wall of the trigger plate 20 is fixedly connected to a switch 24. The column 2 is fixedly connected to a discharge pipe 29, and a solenoid valve 30 is arranged in the discharge pipe 29. The solenoid valve 30 is The normally closed solenoid valve can be opened by powering on. The solenoid valve 30 is electrically connected to the switch 24 through a wire. When the switch 24 is pressed, the solenoid valve 30 can be powered on and opened. It should also be noted that the discharge pipe 29 is a high-temperature resistant ceramic tube, which can withstand the high temperature of the molten metal after thermite reaction, and the solenoid valve 30 is also a high-temperature resistant solenoid valve, which has a ceramic valve core, so it can also withstand high temperatures. After the guide rod is fixed, the servo motor 5 is started to rotate 180° clockwise. At this time, the driving shaft 6 drives the driving pulley 7 to rotate, and the rotation of the driving pulley 7 drives the driven pulley 9 through the synchronous belt 25. Rotate 180°. During the rotation, the driven pulley 9 pulls the trigger plate 20 through the push-pull block 22, and the trigger plate 20 drives the slider 11 to slide. The sliding of the slider 11 drives the pump block 13 to slide through the connecting rod 14, and the pump block 13 drives the follower block 16 to move through the hydraulic oil, so that the slider 11 and the follower block 16 move toward each other synchronously, and the two half molds 19 move toward each other synchronously until the two half molds 19 are closed, thereby completing the automatic mold closing, without manual opening and closing of the mold, and without operating near the main welding position, ensuring an excellent working environment, while avoiding burns and improving safety.

[0032] It is worth mentioning that after the two half molds 19 are closed, the two half molds 19 are against each other and cannot move further, while the push-pull block 22 is still pulling the trigger plate 20. Since the slider 11 cannot slide further at this time, the trigger plate 20 will compress the first spring 23 and make the trigger plate 20 slide relative to the slider 11, and at the same time, the clamping pressure between the two half molds 19 will continue to increase until the trigger plate 20 contacts the switch 24. At this time, the switch 24 is triggered, so that the solenoid valve 30 is opened, and the molten metal in the aluminum heat tank 3 is discharged through the discharge pipe 29 and enters the mold formed by the two half molds 19. The steel claws and the guide rods are subjected to aluminum heat welding. While ensuring a certain clamping pressure, welding can also be automatically started after the pressure reaches the specified value. This not only improves the degree of automation of the tooling, but also ensures a stable clamping pressure, thereby avoiding leakage between the half molds 19.

[0033] The rotating seat 4 is provided with a plurality of clamping and positioning mechanisms, the clamping and positioning mechanisms include a plurality of round-shaped cavities 31, the round-shaped cavities 31 correspond to the placement slots 49 one by one, and the rotating seat 4 is penetrated and fixedly connected with a plurality of fixed tubes 32, each four fixed tubes 32 form a group, and the four fixed tubes 32 are located at the four corners of the placement slot 49 (such as Figure 5As shown in the figure, the fixed tube 32 connects the corresponding placement groove 49 with the round cavity 31, and the fixed tube 32 is sealed and slidably connected with a sliding column 33. A damping pad is also provided at the sliding connection between the sliding column 33 and the fixed tube 32, so that there is a certain friction resistance between the sliding between the two, and a force is applied to the hydraulic oil. The internal pressure of the hydraulic oil is equal everywhere. The friction force will make the four sliding columns 33 slide synchronously to ensure the accurate positioning. One end of the sliding column 33 located in the placement groove 49 is fixedly connected with a clamping block 34, and the side wall of the column 2 is provided with an annular groove 39, and the inner wall of the annular groove 39 is fixedly connected with The convex block 40 and the rotating seat 4 are provided with a plurality of through holes 35, and the through holes 35 connect the corresponding circular cavity 31 with the annular groove 39. A driving block 36 is sealed and slidably connected in the through hole 35. Two mounting plates 37 are fixedly connected to the side wall of the driving block 36. A guide wheel 38 is rotatably connected between the two mounting plates 37 through a bearing. A permanent magnet 48 is arranged in the column 2. A driven gear ring 27 is fixedly connected to the lower surface of the rotating seat 4. The driving gear 26 meshes with the driven gear ring 27. The gear ratio of the driving gear 26 and the driven gear ring 27 is determined by the number of the placement grooves 49, so as to ensure that when the driving gear 26 rotates one circle, Under this condition, the next placement slot 49 can be accurately rotated to the bottom of the discharge pipe 29, the round cavity 31 and the through hole 35 are filled with hydraulic oil, the steel claw is placed in the placement slot 49, and the four feet of the steel claw correspond to the four clamping blocks 34, and then the servo motor 5 is started to make the servo motor 5 rotate counterclockwise for one circle. Due to the setting of the one-way bearing, the servo motor 5 drives the driving gear 26 to rotate through the driving shaft 6, while the driving pulley 7 does not rotate. The rotation of the driving gear 26 drives the driven gear ring 27 meshing with it to rotate, and drives the rotating seat 4 to rotate, and the steel claw is rotated to the guide block 28, during the rotation process, the guide wheel 38 contacts the protrusion 40, so that the driving block 36 slides into the through hole 35, thereby pumping the hydraulic oil into the circular cavity 31, and then entering the four fixed tubes 32 from the circular cavity 31, so that the four sliding columns 33 drive the clamping block 34 to move synchronously toward the steel claw and abut against the steel claw to clamp it. Due to the synchronous movement, the center of the clamped steel claw will be located on the same axis as the center of the placement groove 49 after clamping, thereby completing automatic clamping without manual operation, greatly reducing labor intensity, and avoiding errors caused by manual operation to ensure welding quality.

[0034] It should be noted that the driving block 36 is made of ferromagnetic material and can be adsorbed by the permanent magnet 48 , while the column 2 is made of high-temperature resistant ceramic material to avoid affecting the magnetism of the permanent magnet 48 .

[0035] A plurality of cavities 41 are provided in the rotating seat 4, and a plurality of pump inlet pipes 44 and return pipes 45 are fixedly connected through the rotating seat 4, and the pump inlet pipes 44 and the return pipes 45 connect the corresponding cavities 41 with the through-holes 35, and a function plate 42 is sealingly and slidably connected in the cavity 41, and a plurality of second springs 43 are fixedly connected between the function plate 42 and the inner bottom wall of the cavity 41, and a pressure relief valve 46 is provided in the pump inlet pipe 44, and the pressure relief valve 46 can be opened when the pressure reaches a certain value, which is the prior art and will not be described in detail here, and a one-way valve is provided in the return pipe 45, and the one-way valve in the return pipe 45 only allows the hydraulic oil to enter the through-hole 35 from the cavity 41, and a hole is provided at the bottom of the cavity 41 (not shown in the figure). After the clamping is completed, as the driving block 36 continues to slide, the clamping block 34 cannot continue to move, but its clamping force on the steel claw continues to increase, thereby gradually increasing the pressure in the internal hydraulic oil until it increases to the opening value of the pressure relief valve 46. The pressure relief valve 46 opens, and the hydraulic oil is pumped into the cavity 41 through the pumping pipe 44, so that the functional plate 42 slides down and the excess hydraulic oil is stored. Due to the setting of the pressure relief valve 46, each time the steel claw is clamped, a stable clamping force can be guaranteed, thereby ensuring the stability of the steel claw after clamping, and further ensuring the welding quality.

[0036] The cross section of the clamping block 34 is L-shaped, and its surface is covered with a rubber layer. The rubber layer prevents slipping after clamping and ensures stable clamping. The cross section of the guide block 28 is U-shaped, and a rubber pad is glued to its inner wall. The setting of the rubber pad prevents the guide rod inserted into the guide block 28 from slipping due to friction.

[0037] A protective cover 47 is fixedly connected to the upper surface of the tooling seat 1. The setting of the protective cover 47 prevents the gears and the pulleys from being exposed to the outside to avoid accidental injuries to the workers, thereby improving the safety of the tooling.

[0038] In the present invention, the thermite material is first placed in the thermite tank 3 to undergo thermite reaction to generate molten metal for later use.

[0039] The steel claw is placed in the placement groove 49, and the four feet of the steel claw correspond to the four clamping blocks 34, and then the servo motor 5 is started to make the servo motor 5 rotate counterclockwise for one circle. Due to the setting of the one-way bearing, the servo motor 5 drives the driving gear 26 to rotate through the driving shaft 6, while the driving pulley 7 does not rotate. The rotation of the driving gear 26 drives the driven gear ring 27 meshing with it to rotate, and drives the rotating seat 4 to rotate, and the steel claw is rotated to the bottom of the guide block 28. During the rotation process, the guide wheel 38 contacts the protrusion 40, so that the driving block 36 slides into the through hole 35, thereby pumping the hydraulic oil into the circular cavity 31, and then entering the four fixed tubes 32 from the circular cavity 31, so that the four sliding columns 33 drive the clamping blocks 34 to move synchronously toward the steel claw and resist the steel claw to clamp it. Due to the synchronous movement, the center of the clamped steel claw will be located on the same axis as the center of the placement groove 49.

[0040] After clamping is completed, as the driving block 36 continues to slide, the clamping block 34 cannot continue to move, but its clamping force on the steel claw continues to increase, so that the pressure in the internal hydraulic oil gradually increases until it increases to the opening value of the pressure relief valve 46. The pressure relief valve 46 opens, and the hydraulic oil is pumped into the cavity 41 through the pumping pipe 44, so that the functional plate 42 slides down and the excess hydraulic oil is stored.

[0041] After the rotation stops, the guide rod is inserted into the guide block 28, and the electric push rod 50 is operated to move the guide rod downward, and a certain gap is ensured between the guide rod and the lower steel claw.

[0042] After the guide rod is fixed, the servo motor 5 is started to rotate 180° clockwise. At this time, the driving shaft 6 drives the driving pulley 7 to rotate, but does not drive the driving gear 26 to rotate. The rotation of the driving pulley 7 drives the driven pulley 9 to rotate 180° through the synchronous belt 25. During the rotation, the driven pulley 9 pulls the trigger plate 20 through the push-pull block 22, and the trigger plate 20 drives the slider 11 to slide. The sliding of the slider 11 drives the pump block 13 to slide through the connecting rod 14, and the pump block 13 drives the follower block 16 to move through the hydraulic oil, so that the slider 11 and the follower block 16 move synchronously towards each other, so that the two half molds 19 move synchronously towards each other until the two half molds 19 are closed.

[0043] After the two half molds 19 are closed, the two half molds 19 are against each other and cannot move further, while the push-pull block 22 is still pulling the trigger plate 20. Since the slider 11 cannot slide further at this time, the trigger plate 20 will compress the first spring 23 and make the trigger plate 20 slide relative to the slider 11, while the clamping pressure between the two half molds 19 is continuously increased until the trigger plate 20 contacts the switch 24. At this time, the switch 24 is triggered, so that the solenoid valve 30 is opened, and the molten metal in the aluminum heat tank 3 is discharged through the discharge pipe 29 and enters the mold formed by the two half molds 19, and the steel claws and the guide rods are subjected to aluminum heat welding.

[0044] When the molten metal fills the mold, the solenoid valve 30 is powered off and closed, the injection is stopped, and the molten metal is waited for to be formed.

[0045] After molding, the electric push rod 50 is first started to drive the guide block 28 to move upward and separate from the guide rod, and then the servo motor 5 is turned on to make it continue to rotate 180° clockwise. At this time, the driven pulley 9 continues to rotate, and the trigger plate 20 is pushed by the push-pull block 22 to reset the slider 11. The slider 11 drives the follower block 16 to reset through the pump block 13 and the hydraulic oil, so that the two half molds 19 move back to back to open the mold.

[0046] After the mold is opened, the servo motor 5 rotates counterclockwise for one circle, so that the steel claw in the next placement slot 49 rotates to the bottom of the guide block 28, and the welded anode guide rod leaves the bottom of the guide block 28. During the leaving process, under the magnetic attraction of the permanent magnet 48, the driving block 36 is reset, so that the hydraulic oil in the cavity 41 is pumped back into the through hole 35 through the reflux pipe 45, and at the same time, the hydraulic oil in the four fixed pipes 32 is pumped back into the through hole 35, so that the clamping block 34 leaves the steel claw and releases the clamping.

[0047] At this time, the welding of the anode guide rod is continued according to the above steps, and the last welded anode guide rod continues to be cooled in the placement tank 49. After cooling to a suitable temperature, the welded anode guide rod is hoisted down by the hoisting device.
