Description

Technical Field

[0001] This utility model relates to an aluminum foil corrosion tension testing device, belonging to the field of aluminum foil experimental auxiliary equipment. Background Technology

[0002] Currently, medium and high voltage electrode foils are generally produced using electrolytic corrosion. The corrosion process typically includes four main steps: pretreatment, pitting corrosion, pit expansion corrosion, and post-treatment, to create uniformly distributed, high-density tunnels with appropriate pore size and length on the surface. On the production line, the speed difference during aluminum foil transport generates tension. This force can cause deformation in different parts of the foil, and the magnitude of the tension directly affects the performance and quality of the foil. Too much tension will tighten the foil and cause deformation, while too little will cause it to loosen. Therefore, the tension in production is generally controlled at around 10 kg. However, in laboratory research and development experiments on aluminum foil electrolytic corrosion, the electrolytic corrosion experimental apparatus used lacks the function of applying tension, i.e., the tension is zero. These are static experiments that ignore the role of tension in aluminum foil electrolytic corrosion and cannot accurately simulate the corrosion process on the production line. In other words, the existing experimental apparatus does not utilize tension in the aluminum foil corrosion experiment, and the corrosion parameters adjusted on the production line are not comprehensive enough, resulting in a certain error between the experimental results and the production results. This raises questions about the accuracy of the experimental results and hinders research on aluminum foil electrolytic corrosion experiments. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aluminum foil corrosion tension testing device. This device solves the problem that existing aluminum foil testing devices cannot apply tension to aluminum foil, thereby accurately simulating the aluminum foil corrosion process on the production line, reducing the error between experimental results and production results, and improving the accuracy of experimental results.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An aluminum foil corrosion tension test apparatus includes a DC regulated power supply, an experimental platform, a glass cup, a graphite electrode, a thermometer, a tension gauge, weights, an experimental mold mounting plate, and an aluminum foil clamping plate assembly. The experimental platform has a groove in the middle for placing the glass cup, and a heating device is installed in the groove to heat the glass cup; two mounting plate retainers are provided on the experimental platform and on both sides of the groove for fixing the experimental mold mounting plate; a support rod is provided at one end of the experimental platform, and a crossbar is provided at the top of the support rod. One end of the crossbar is located above the groove. The upper end of the tension gauge is connected to a pull rope A, which is placed on the crossbar and connected to a pulley A. A pull rope B is provided on the pulley A, and a clip is connected to each end of the pull rope B; The experimental mold mounting plate has a rectangular through hole in the middle, and a graphite electrode is arranged on each side of the rectangular through hole, and the graphite electrode is fixedly connected to the experimental mold mounting plate; the experimental mold mounting plate has a thermometer mounting hole for thermometer installation and positioning; the two ends of the rectangular through hole are provided with clamping fasteners for fixing the aluminum foil clamping plate assembly. The clamping plate assembly includes clamping plates A and B that can be fitted together, and both clamping plates A and B have square holes in the middle; clamping plate A has a locking block A at its upper end; clamping plate B has a locking block B at its upper end, and clamping plate B has a locking groove on one side of its lower end, and the lower end of clamping plate A is inserted into the locking groove so that clamping plate A and clamping plate B are tightly fitted together. The positive terminal of the DC regulated power supply is connected to the aluminum foil used in the experiment, and the negative terminal of the DC regulated power supply is connected to the graphite electrode; the glass cup containing the electrolyte is placed in the groove.

[0005] The operating procedure for the above aluminum foil corrosion tension test apparatus is as follows: S1. First, place the glass cup containing the electrolyte in the groove of the experimental table. At the same time, fix the graphite electrodes on both sides of the rectangular through hole of the experimental mold mounting plate. Then, cover the groove and the glass cup with the experimental mold mounting plate, so that the graphite electrodes are placed in the electrolyte in the glass cup. Then, fix the experimental mold mounting plate to the experimental table with the mounting plate retainer. Take the thermometer and insert it into the electrolyte in the glass cup through the thermometer mounting hole of the experimental mold mounting plate. At the same time, turn on the heating device in the groove to heat the electrolyte to the temperature required for the experiment. S2. Take the tension gauge and place the connected pull rope A on the crossbar supported by the support rod. Take the pull rope B and wrap it around the pulley A connected to the pull rope A. Hang weights on the hook of the tension gauge according to the experimental needs. Next, take clamp A and clamp B. First, place the bottom end of the aluminum foil to be used in the experiment into the slot of clamp B. Then, attach clamp A and clamp B together, and attach the clips A and B together. Insert the lower end of clamp A into the slot of clamp B to press down the bottom end of the aluminum foil. Then, extend the upper end of the aluminum foil from the top of clips A and B. Finally, insert clamp A and clamp B together into the experimental... The rectangular through-hole of the mold mounting plate is fitted with clamp A or clamp B. The two ends of clamp A and clamp B are clamped on the experimental mold mounting plate. Clamp retainers are used to fix clamp A and clamp B to the experimental mold mounting plate. Electrolyte comes into contact with aluminum foil through the square holes of clamp A and clamp B. Then, the clamps at both ends of the pull rope B are clamped to the upper end of the aluminum foil to apply tension to the aluminum foil. At the same time, the positive terminal of the DC regulated power supply is connected to the experimental aluminum foil, and the negative terminal of the DC regulated power supply is connected to the graphite electrode. Finally, the DC regulated power supply is turned on to conduct the experiment.

[0006] Furthermore, a fixed post is provided on each of the two upper sides of the card block A, and a shaft is connected between the two fixed posts. A carbon fiber tube is sleeved on the shaft, and the carbon fiber tube can rotate relative to the shaft. The aluminum foil corrosion tension experimental device also includes a carbon fiber rod, and the clamps at both ends of the pull rope B are clamped to the ends of the carbon fiber rod. During the experiment, the upper end of the aluminum foil is unfolded and wrapped around the carbon fiber rod for fixation, and the aluminum foil and carbon fiber rod can be clamped together for fixation. Then, the two ends of the pull rope B are clamped to the two ends of the carbon fiber rod, and the side of the aluminum foil is attached to the outside of the carbon fiber tube. Then, by adding weights, the pull rope B is pulled and the carbon fiber rod is pulled, thereby applying a certain tension to the aluminum foil and conducting the experiment. While the carbon fiber rod pulls the aluminum foil, the carbon fiber tube rotates to guide the aluminum foil. When the tension is balanced, the carbon fiber tube can also provide a certain support to the aluminum foil from the side. This allows the aluminum foil to be evenly stressed, and the tension can be evenly distributed on the aluminum foil, which helps to improve the accuracy of the experiment.

[0007] Furthermore, the carbon fiber rod has lugs at both ends for connecting to the two ends of the pull rope B.

[0008] Furthermore, a fixing post is provided on each of the two upper sides of the card block A. A U-shaped fixing buckle is provided on the upper inner side of the two fixing posts. A carbon fiber rod is provided above the card block A. The two ends of the carbon fiber rod are engaged in the corresponding U-shaped fixing buckles and can rotate relative to the U-shaped fixing buckles. A gap is left between the carbon fiber rod and the U-shaped fixing buckles. During the experiment, the two ends of the carbon fiber rod are engaged in the U-shaped fixing buckles. Then, the upper end of the aluminum foil is attached to the carbon fiber rod, and the carbon fiber rod is rotated to wrap around the aluminum foil and then fixed with a clamp. Then, the two ends of the pull rope B are clamped to the two ends of the carbon fiber rod. Then, weights are added to apply tension to the carbon fiber rod, so that the aluminum foil is balanced and the resistance is reduced.

[0009] Furthermore, a heating device is provided at the bottom of the groove to heat the glass, and the heating device includes an electric furnace or an electric ceramic furnace.

[0010] Furthermore, the mounting plate holder includes a base A, a fixing plate A, and two locking screws A. The base A is fixed to the experimental table, and the fixing plate A has an elongated hole. The width of the elongated hole is greater than the diameter of the locking screw A but smaller than the diameter of the nut of the locking screw A. After the experimental mold mounting plate is installed, one end of the fixing plate A is placed on the experimental mold mounting plate, and the other end is placed on the base A. Then, one of the locking screws A is used to fix the fixing plate A to the base A, and the other locking screw A is used to press the experimental mold mounting plate tight.

[0011] Furthermore, the clamping device includes a base B, a pad B, and a fixing plate B. The base B is fixed to the experimental mold mounting plate, the pad B is fixedly connected to the upper end of the base B, one end of the fixing plate B is rotatably connected to the top of the pad B, and the other end has a screw hole with a locking screw B. After the clamping assembly is installed, the fixing plate B on the pad B is rotated so that one end is positioned above the clamping blocks A and B of the clamping plates A and B. Then, the locking screw B is inserted into the screw hole and tightened, so that the lower end of the locking screw B tightly abuts against the clamping blocks A and B, thereby pressing the clamping assembly and preventing the clamping assembly and aluminum foil from being pulled out when tension is applied.

[0012] Furthermore, each end of the crossbar is provided with a U-shaped bracket, and a roller shaft is provided inside the U-shaped bracket. A roller is fitted on the roller shaft, and both ends of the roller shaft are rotatably connected to the U-shaped bracket. The rollers facilitate the movement of the pull rope A on the crossbar for traction.

[0013] Furthermore, the positive terminal of the DC regulated power supply is connected to a stainless steel clamp via a wire, and then the aluminum foil is clamped by the stainless steel clamp.

[0014] Compared with existing technologies, this technical solution has the following beneficial effects: This invention features a simple and quick-to-operate device with low implementation difficulty. It adds the function of applying tension to the aluminum foil and ensures uniform tension, meeting the requirements of aluminum foil corrosion tension experiments. It more closely resembles the aluminum foil production corrosion process, better replicating the production state and facilitating the resolution of production problems through experiments. This provides assistance in studying the effect and laws of tension on aluminum foil corrosion. The clamping assembly, with interlocking grooves at the bottom of clamps A and B, secures the bottom of the aluminum foil, resisting the applied tension and preventing it from being pulled out when clamped, thus ensuring the smooth conduct of the experiment.
