Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell cover processing equipment, and more specifically, to an auxiliary tooling for shaping and welding electrolytic cell covers. Background Technology

[0002] As a core piece of equipment in the electrolysis industry, the structural stability and assembly precision of the electrolytic cell cover directly affect the sealing, heat preservation, and safe production efficiency of the electrolysis process. The cell cover is typically assembled from curved aluminum plates, a metal support frame, end plates, and support strips through welding, riveting, and other methods. The shaping precision of the curved aluminum plate and the fit between the support frame and the aluminum plate are crucial factors determining the overall quality of the cell cover.

[0003] In the existing electrolytic cell cover processing, aluminum plates must first be pressed into a preset arc shape and then welded to the support frame for positioning. However, the existing auxiliary tooling for shaping and welding electrolytic cell covers has many key problems: the support platforms of the existing auxiliary tooling are mostly integrated rigid structures with a fixed arc, which have poor adaptability and lack a precise support detection mechanism, easily leading to uneven stress and local deformation of aluminum plates of different specifications; furthermore, the placement slots used to place the support frame of the cell cover lack effective guidance and automatic clamping structures, making them prone to positioning misalignment and loosening due to vibration during welding. The low degree of automation in each process and the high dependence on operator skills ultimately result in low precision in cell cover processing, insufficient production efficiency, and poor consistency of batch products, failing to meet the needs of modern industrial mass production.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1-5 As shown, the main body of this embodiment is an auxiliary tooling for shaping and welding an electrolytic cell cover, including a bracket, a support platform, a pressing device, a clamping device, and a control system. The support platform and the pressing device are arranged vertically on the bracket, with the support platform fixedly connected to the bracket to provide a stable support surface. The pressing device is located inside the bracket and can perform lifting and lowering movements. The clamping device is located at the end of the support platform and is used for the fitting and positioning of the end plate of the cell cover with the aluminum plate. The control system is electrically connected to the pressing device and the clamping device to realize the coordinated control of each component.

[0027] Furthermore, the support structure is an integral load-bearing foundation, comprising two relatively parallel vertical rectangular frames 1, each rectangular frame 1 consisting of vertical and horizontal members fixedly connected together. Multiple connecting rods 2 are evenly distributed and fixedly connected along the height direction between the vertical members of the two rectangular frames 1, with both ends of the connecting rods 2 welded and fixed to the vertical members on both sides, forming a stable frame structure.

[0028] The rectangular frame 1 has an inverted V-shaped frame 3 fixed at the top center. The bottom sides of the inverted V-shaped frame 3 are fixedly connected to the horizontal bar at the top of the rectangular frame 1. A horizontally arranged beam is fixedly connected between the tops of the two inverted V-shaped frames 3. The beam is welded to the top of the inverted V-shaped frame 3 to enhance the structural rigidity of the top of the support.

[0029] Furthermore, the support platform includes a horizontally arranged base plate 4, the two ends of which are fixedly connected to the inner wall of the vertical rod of the rectangular frame 1. The base plate 4 is made of high-strength steel plate to ensure load-bearing stability.

[0030] The base plate 4 has an arc-shaped support frame 5 fixed to its top. The arc of the arc-shaped support frame 5 is adapted to the aluminum plate of the channel cover, and the whole is located directly below the inverted V-shaped frame 3. Several fine-adjustment receiving blocks 6 are evenly spaced along the length of the surface of the arc-shaped support frame 5. The top of the fine-adjustment receiving block 6 is an arc-shaped surface adapted to the aluminum plate, and its bottom is fixedly connected to the top of the piston of the first telescopic cylinder. The bottom of the cylinder body of the first telescopic cylinder is fixedly connected to the top of the arc-shaped support frame 5. The first telescopic cylinder is an electric push rod or a hydraulic cylinder 19, which is electrically connected to the control system. It can drive the fine-adjustment receiving block 6 to move up and down through the control system to achieve support adaptation for aluminum plates of different thicknesses.

[0031] Secondly, a wear-resistant silicone pad 8 is attached to the top of the fine-tuning receiving block 6. The surface of the silicone pad has a diamond-shaped anti-slip texture, which can not only prevent the aluminum plate surface from being scratched, but also enhance the friction between the aluminum plate and the receiving block to prevent slippage.

[0032] In addition, the arc-shaped support frame 5 has grooves 9 along its length on both sides, which are used to accommodate the support frame of the trough cover. An elastic rubber guide strip 10 is attached to the inner wall of the groove 9. The guide strip 10 has a semi-circular cross-section and guides the insertion of the support frame. A first positioning pin 11 is slidably connected to the inner wall of the groove 9 near both ends. The axis of the first positioning pin 11 is parallel to the width direction of the groove 9. The outer end of the first positioning pin 11 extends into the end of the groove 9, and the inner end extends into the groove 9. A spring 12 is provided between the first positioning pin 11 and the groove 9. The spring 12 always applies an inward elastic force to the first positioning pin 11, causing the first positioning pin 11 to naturally extend into the groove 9, thus initially limiting the end of the support frame.

[0033] Secondly, clamping push blocks 13 are symmetrically provided on the sides of the groove 9. The clamping push blocks 13 are pneumatic push rods or electric push rods, and their cylinders are fixedly connected to the side of the arc-shaped support frame 5. The end of the push rod faces the inside of the groove 9 and is electrically connected to the control system. When the support frame is placed in the groove 9, the control system drives the clamping push blocks 13 on both sides to extend synchronously, clamping and fixing the support frame laterally.

[0034] In addition, an infrared sensor 14 is embedded on the side of the adjacent fine-tuning support block 6 perpendicular to the width direction of the arc-shaped support frame 5 (i.e., the side facing the groove 9 of the aluminum plate). The detection direction of the infrared sensor 14 is perpendicular to the side and is used to detect the distance between the fine-tuning support block 6 and the side wall of the groove 9 of the aluminum plate. When the fine-tuning support block 6 rises to contact the aluminum plate, if the infrared sensor 14 on the same fine-tuning support block 6 detects that the distance is equal, it sends a signal to the control system to confirm that the support block is in place without displacement, thus avoiding the aluminum plate from tilting or deforming.

[0035] Furthermore, the pressing device includes a main beam 15 and a driving assembly. The main beam 15 is horizontally arranged directly below the inverted V-shaped frame 3, and its length is adapted to the arc-shaped support frame 5. Arc-shaped pressure rods 16 are fixedly connected to both sides of the lower part of the main beam 15. The curvature of the arc-shaped pressure rods 16 is adapted to the arc-shaped support frame 5 and fits against the convex surface of the aluminum plate. The arc-shaped pressure rods 16 are provided with positioning structures for positioning the welding or riveting positions of the slot cover.

[0036] Secondly, multiple spaced auxiliary rods 17 are fixedly connected between each of the two arc-shaped compression rods 16 and the main beam 15. The auxiliary rods 17 are evenly arranged along the length of the arc-shaped compression rods 16, with one end welded to the main beam 15 and the other end welded to the arc-shaped compression rods 16. A reinforcing rod 18 is connected between the top of the arc-shaped compression rod 16 and the main beam 15. The reinforcing rod 18 is arranged at an angle, with both ends hinged to the auxiliary rods 17 and the main beam 15 respectively, forming a triangular stable structure to enhance the overall rigidity of the pressing device.

[0037] Furthermore, the driving component is a hydraulic cylinder 19 with the piston facing downwards. The upper and lower ends of the cylinder body of the hydraulic cylinder 19 are fixedly connected to the bottom of the inverted V-shaped frame 3 and the crossbar of the rectangular frame 1, respectively. The piston end of the hydraulic cylinder 19 is hinged to the top center of the main beam 15 via a hinge, ensuring that the main beam 15 can be smoothly raised and lowered when the piston extends or retracts. A pressure sensor and a hydraulic lock are connected in series in the oil circuit of the hydraulic cylinder 19. The pressure sensor is used to detect the holding pressure and feed it back to the control system. The hydraulic lock is used to lock the oil circuit when the hydraulic cylinder 19 stops moving, preventing the main beam 15 from falling unexpectedly.

[0038] Furthermore, the positioning structure on the arc-shaped pressure rod 16 includes a groove formed on the arc-shaped pressure rod 16 and a slidable positioning block 20 slidably fitted within the groove. The groove extends along the length of the arc-shaped pressure rod 16. The cross-section of the slidable positioning block 20 is adapted to the groove, and a positioning groove 21 is formed on its top. The shape of the positioning groove 21 is adapted to the tooling at the welding or riveting position. The side of the groove is provided with scale markings 22 to indicate the position of the slidable positioning block 20. A locking bolt 23 is provided through the side of the slidable positioning block 20. The end of the locking bolt 23 abuts against the arc-shaped pressure rod 16. Tightening the locking bolt 23 can fix the slidable positioning block 20 at any position in the groove.

[0039] Furthermore, an elastic silicone pad 24 is attached to the side of the arc-shaped pressure rod 16 that contacts the aluminum plate. The elastic silicone pad 24 has a built-in first local pressure sensor, which is electrically connected to the control system and can detect the local pressure distribution in real time during the pressing process. When the pressure in a certain area exceeds a preset threshold, the control system adjusts the height of the fine-tuning support block 6 in the corresponding area to achieve pressure balance.

[0040] Furthermore, the auxiliary rod 17 is a hydraulically telescopic structure, and the reinforcing rod 18 is also a telescopic structure. The cylinder of the auxiliary rod 17 is fixedly connected to the main beam 15, and the piston rod is fixedly connected to the arc-shaped pressure rod 16 and electrically connected to the control system. During welding operations, the auxiliary rod 17 can be shortened via the operation panel 30, causing the arc-shaped pressure rod 16 to partially rise and expose the welding area. After the operation is completed, the auxiliary rod 17 extends and returns to its original position to ensure holding stability.

[0041] Furthermore, the clamping device includes two second telescopic cylinders 25 disposed at the end of the arc-shaped support frame 5. The two second telescopic cylinders 25 are symmetrically arranged on both sides of the arc-shaped support frame 5. The bottom of the cylinder body is fixedly connected to the side of the end of the arc-shaped support frame 5. The piston end of the second telescopic cylinder 25 extends in a direction away from the support frame, and a fixing plate 26 is fixedly connected to the end. The fixing plate 26 is L-shaped and is adapted to the side and bottom of the end plate of the groove cover.

[0042] A second positioning pin 27 is threaded through the fixing plate 26. The axis of the second positioning pin 27 is perpendicular to the fixing plate 26. An anti-slip rubber pad 28 is attached to the end of the pin located inside the fixing plate 26. The second positioning pin 27 is driven to rotate by a motor 29 located outside the fixing plate 26. The motor 29 is slidably connected to the fixing plate 26. A second local pressure sensor is installed inside the anti-slip rubber pad 28. The motor 29 and the second local pressure sensor are electrically connected to the control system. The insertion length of the second positioning pin 27 can be adjusted by driving the motor 29 to rotate, and the clamping pressure can be monitored by the second local pressure sensor, thereby ensuring that the anti-slip rubber pad 28 fits tightly against the end plate, achieving precise positioning and clamping of the end plate.

[0043] Furthermore, the control system includes an operation panel 30 and a controller, which integrates a touch screen and physical shortcut keys. The touch screen is used for parameter setting, operation status display and fault query, and the physical shortcut keys include commonly used function keys such as start, stop, and emergency stop.

[0044] The controller is a PLC controller, which is built into the control box 31 on the operation panel 30. It is electrically connected to the hydraulic cylinder 19, the first telescopic cylinder, the clamping push block 13, the second telescopic cylinder 25 of the clamping device, the first local pressure sensor, the infrared sensor 14, etc. It receives the signals from each sensor and controls the actions of each actuator according to the preset program to realize the automated shaping welding auxiliary process.

[0045] Working principle of this device 1. The operator inputs the specifications of the trough cover through the control panel 30. The control system automatically presets the holding pressure, fine-tunes the initial height of the receiving block 6, and manually adjusts the position of the sliding positioning block 20 and fixes it with the locking bolt 23 to ensure that the positioning groove 21 is aligned with the welding / riveting position.

[0046] 2. Place the support frame of the trough cover into the grooves 9 on both sides of the arc support frame 5. The elastic rubber guide strip 10 guides the frame into place, and the first positioning pins 11 at both ends are initially limited by the action of the spring 12. At the same time, place the aluminum plate on the fine-tuning receiving block 6, with the concave surface of the aluminum plate facing down and contacting the silicone pad of the receiving block.

[0047] 3. The control system activates the infrared sensor 14, which drives the first telescopic cylinder to raise the fine-tuning receiving block 6. When the sensor detects that the receiving block and the aluminum plate groove 9 are in place without any offset, the first telescopic cylinder stops moving. Then the clamping push block 13 on the side of the groove 9 extends to clamp and fix the support frame laterally.

[0048] 3. The pressing device is activated via the operation panel 30. The piston of the hydraulic cylinder 19 extends, causing the main beam 15 and the arc-shaped pressure rod 16 to descend. The elastic silicone pad 24 of the arc-shaped pressure rod 16 contacts the concave surface of the aluminum plate. The pressure sensor provides real-time feedback of the pressure value. After the preset pressure is reached, the hydraulic cylinder 19 stops, and the hydraulic lock locks the oil circuit. If the first local pressure sensor detects uneven pressure, the control system adjusts the height of the corresponding fine-tuning support block 6 to ensure that the aluminum plate is subjected to uniform force.

[0049] 4. Place the end plate against the end of the aluminum plate, activate the second telescopic cylinder 25 of the clamping device to move the fixing plate 26 closer to the end plate, rotate the second positioning pin 27 to press the anti-slip rubber pad 28 against the end plate, and achieve precise fitting and positioning of the end plate of the trough cover.

[0050] 5. When the operator performs welding work on the trough cover, if it is necessary to weld the area covered by the auxiliary rod 17, the corresponding auxiliary rod 17 is shortened through the control panel 30 to expose the welding position; after the welding is completed, the auxiliary rod 17 is extended and reset.

[0051] 6. After welding is completed, the control system sequentially controls the second positioning pin 27 of the clamping device to release, the second telescopic cylinder 25 to reset, the hydraulic cylinder 19 of the pressing device to retract and drive the arc-shaped pressure rod 16 to rise, the clamping push block 13 to retract, and the operator to take out the forming groove cover; all parts of the equipment automatically reset, ready for the next round of operation.

[0052] In summary, this device achieves the following beneficial effects through optimized structural design: This device ensures that the aluminum plate is supported in place by adjusting the receiving block 6 in conjunction with the infrared sensor 14. The sliding positioning block 20 and the scale mark 22 achieve precise positioning of the welding position. The second positioning pin 27 of the clamping device ensures the fitting accuracy of the end plate and effectively prevents the overall shaping error from being too large.

[0053] The fine-tuning receiving block 6, the sliding positioning block 20, and the hydraulic telescopic auxiliary rod 17 of the first telescopic cylinder in this device can be adapted to groove covers of different specifications and thicknesses without the need to replace the main tooling body.

[0054] The automated control in this device reduces manual intervention, shortens the preparation time for single-slot cover shaping, and reduces reliance on operator skills.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
