Description

Technical Field

[0001] This invention relates to the field of battery casing processing, and more particularly to an air-cooled quenching apparatus for extrusion molding of battery casings. Background Technology

[0002] The battery casing refers to the outer protective shell structure of a battery. It is generally manufactured by various molds through extrusion, vacuum forming, or other methods.

[0003] For battery casings extruded from molten metal, cooling and quenching are usually required during the forming process using a quenching device. Existing methods generally involve water cooling or air cooling. Water cooling, which involves spraying to cool the casing, is efficient and fast, but may cause water spots to appear on the surface of the casing after forming. Air cooling, while providing good forming results, has a long cooling time and is less efficient. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an air-cooled quenching device for extrusion molding of battery casings. The specific technical solution is as follows:

[0005] A wind-cooled quenching apparatus for extruding battery casings includes:

[0006] A heat dissipation frame has a vertically penetrating cavity in the middle, and several intake fans that supply air to the cavity are detachably arranged around the heat dissipation frame. A dust filter cloth is detachably arranged inside the heat dissipation frame and is located on the air outlet side of the intake fans.

[0007] The top cover is detachably fixed to the top of the heat dissipation frame. The top cover has several exhaust fans inside that blow air away from the heat dissipation frame. The top cover is equipped with a water supply mechanism, and the cold water outlet of the water supply mechanism contacts the dust filter cloth.

[0008] As an improvement to the above technical solution, the lower surface of the top cover is provided with a number of positioning blocks, and the upper surface of the heat dissipation frame is provided with a number of limiting grooves that match the positioning blocks.

[0009] As an improvement to the above technical solution, the heat dissipation frame includes several positioning channel steels, and the dust filter cloth is detachably disposed on the sides of two adjacent positioning channel steels.

[0010] As an improvement to the above technical solution, the limiting groove is provided at one end of the positioning channel steel.

[0011] As an improvement to the above technical solution, a dustproof net is detachably provided between two adjacent positioning channel steels, and the dustproof net corresponds one-to-one with the dust filter cloth. The inlet fan is provided on the surface of the dustproof net near the dust filter cloth.

[0012] As an improvement to the above technical solution, the side of the positioning channel steel is provided with two sets of limiting plates and two sets of buckles. The inside of the limiting plate has a limiting rail groove that cooperates with the dustproof net. The side of the dust filter cloth has at least two locking blocks, and the two locking blocks are respectively locked into the inside of two adjacent buckles.

[0013] As an improvement to the above technical solution, the water delivery mechanism includes a cotton strip and a liquid hole opened on the surface of the top cover for connecting a water delivery pipe. The cotton strip is adhered to the lower surface of the top cover, one end of the liquid hole extends through the cotton strip, and the cotton strip is attached to the side surface of the filter cloth near the dustproof net.

[0014] As an improvement to the above technical solution, the upper surface of the top cover is provided with several water tanks, each water tank having a connected liquid tank, and the liquid holes are disposed inside the liquid tanks. 。

[0015] The beneficial effects of this invention are:

[0016] 1. The dust filter cloth not only filters out particulate matter in the air supplied by the fan, but also works with the water supply mechanism to wet the dust filter cloth when rapid cooling is required. This allows the heat of the air supplied by the fan to be absorbed by the water, thereby reducing the temperature of the air entering the cavity and accelerating the cooling effect.

[0017] 2. The surface of the top cover is grooved to store water, which makes it easy to detect the remaining water for cooling and to add water and clean it.

[0018] 3. Furthermore, the entire structure is assembled in a modular fashion, which makes it easy to disassemble and assemble the whole structure. Moreover, if the structure is damaged, the damaged part can be replaced for reuse. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] In the quenching of the molding die for battery casing, the existing methods are generally to cool down and quench by water cooling or air cooling. Water cooling is achieved by spraying, which is efficient and fast, but may cause water spots to appear on the surface of the battery casing after molding. Air cooling, on the other hand, has a good molding effect, but the cooling time is long and the efficiency is low.

[0028] To resolve the above issues, please refer to Figure 1-6 A battery casing extrusion molding air-cooled quenching device is provided, comprising: a heat dissipation frame 10 and a top cover 20.

[0029] Specifically, the heat dissipation frame 10 has a vertically penetrating cavity in the middle, and several intake fans 14 that supply air to the cavity are detachably arranged around the heat dissipation frame 10. A dust filter cloth 12 is detachably arranged inside the heat dissipation frame 10 and is located on the exhaust side of the intake fans 14. The top cover 20 is detachably fixed to the top of the heat dissipation frame 10. Several exhaust fans 22 that exhaust air away from the heat dissipation frame 10 are arranged inside the top cover 20. A water supply mechanism is arranged on the top cover 20, and the cold water outlet of the water supply mechanism contacts the dust filter cloth 12.

[0030] The mold is placed inside the vertically penetrating cavity, and then the top cover 20 is used to seal the upper part of the heat dissipation frame 10. Air enters from the side of the heat dissipation frame 10. The incoming airflow passes through the dust filter cloth 12, which blocks particles and dust on the outside. The water supply mechanism wets the dust filter cloth 12 with cold water. This means that when the airflow passes through the dust filter cloth 12, it is not only filtered, but the heat in the airflow is also carried away by the water. This causes the temperature of the airflow entering the cavity from the outside to drop, thereby achieving the effect of enhancing the cooling speed.

[0031] In addition, the low-temperature airflow entering the cavity carries some thin water vapor. Since the water vapor is relatively thin and the surface temperature of the mold is high, not only will water droplets not form, but the heat dissipation effect will be further enhanced. Furthermore, since it is not a direct contact with the water source, water spots will not appear on the surface of the mold, and the cooling speed is faster while ensuring the molding effect.

[0032] In one embodiment, the lower surface of the top cover 20 is provided with a plurality of positioning blocks 21, and the upper surface of the heat dissipation frame 10 is provided with a plurality of limiting grooves 111 that match the positioning blocks 21. That is, the top cover 20 and the heat dissipation frame 10 are fixed by a snap-fit ​​method, so that the top cover 20 can be easily disassembled while ensuring stability.

[0033] In one embodiment, see Figure 2 The heat dissipation frame 10 includes several positioning channel steels 11. The dust filter cloth 12 is detachably set on the side of two adjacent positioning channel steels 11. That is, the positioning channel steels 11 are used as the skeleton to provide support, and the dust filter cloth 12 is used as the connection to form a detachable barrel structure.

[0034] In the above embodiments, although a structurally stable connection is provided, the filter cloth 12 is made of cloth material, which cannot provide strength. If an external impact occurs, not only will the filter cloth 12 be easily damaged, but the positioning channel steel 11 will also tip over. Furthermore, impacts from sharp particles may cause holes to appear in the filter cloth 12. To solve this technical problem, please refer to... Figure 1-4 A dustproof net 13 is detachably installed between two adjacent positioning channel steels 11. The dustproof net 13 corresponds one-to-one with the dust filter cloth 12. The inlet fan 14 is installed on the surface of the dustproof net 13 near the dust filter cloth 12.

[0035] The dustproof net 13 on the outside provides position restriction. The dustproof net 13 not only restricts the position of each positioning channel steel 11, but also provides external blocking, which can block larger particles from the outside. In this case, the filter cloth 12 can be well protected. In addition, since the structural components are detachable, the corresponding positions can be directly removed for replacement and cleaning when structural damage occurs or cleaning is required.

[0036] Please see Figure 2 and Figure 4 When the positioning channel steel 11 is used as a connecting part, the limiting groove 111 is set at one end of the positioning channel steel 11, that is, the connection with the top cover 20 is set at the end of the positioning channel steel 11. In this way, the positioning channel steel 11 can provide support for the top cover 20, making it convenient to adjust the position of the support and ensuring stability.

[0037] In one embodiment, see Figure 2 The positioning channel steel 11 has two sets of limiting plates 112 and two sets of buckles 113 on its side. The limiting plates 112 have limiting rail grooves that cooperate with the dustproof net 13. The dust filter cloth 12 has at least two locking blocks 121 on one side. The two locking blocks 121 are respectively locked into the interior of two adjacent buckles 113. That is, the dustproof net 13 is positioned by means of rail insertion. When disassembling, it can be pulled out directly. The dust filter cloth 12 is fixed by means of snap-fit. The snap-fit ​​structure here is a widely used existing technology. Its snap-fit ​​form is very diverse, so it is not shown in the figure.

[0038] When the card block 121 and the buckle 113 are connected in this embodiment, a counterweight can also be set at the end of the dust filter cloth 12 away from the card block 121 to ensure that the dust filter cloth 12 is taut.

[0039] In one embodiment, see Figure 5 and Figure 6 The water delivery mechanism includes a cotton swab 23 and a liquid hole 242 opened on the surface of the top cover 20 for connecting the water delivery pipe. The cotton swab 23 is adhered to the lower surface of the top cover 20, and one end of the liquid hole 242 extends through the cotton swab 23. The cotton swab 23 is attached to the side surface of the filter cloth 12 near the dustproof net 13.

[0040] When water is introduced into the cotton swab 23 through the liquid hole 242, the cotton swab 23 can absorb the water. Since the cotton swab 23 is in contact with the dust filter cloth 12, when the cotton swab 23 has fully absorbed the water, some of the water will be transferred to the dust filter cloth 12, thus slowly wetting the dust filter cloth 12. When the dust filter cloth 12 is wetted, the airflow sent in by the fan 14 will pass through the wet dust filter cloth 12. The airflow has a certain temperature, while the moisture in the dust filter cloth 12 has a lower temperature. In this case, the moisture in the dust filter cloth 12 will evaporate, taking away the heat in the airflow and making the airflow temperature lower. In this case, when the low-temperature airflow enters the interior of the cavity, a better cooling effect can be achieved.

[0041] Furthermore, since the cotton strip 23 is attached to the side of the dust filter cloth 12 that is close to the dustproof net 13, that is, the cotton strip 23 is set between the dust filter cloth 12 and the dustproof net 13, if the cotton strip 23 has too much moisture and produces water droplets, the airflow will only blow the water droplets onto the dust filter cloth 12, and will not directly contact the mold or the molded body.

[0042] In addition, the airflow after passing through the dust filter 12 contains some thin water vapor produced by evaporation. When the water vapor comes into contact with the mold at a high temperature, it will also produce a certain cooling effect. Since the airflow contains thin water vapor, rather than water droplets or dense water vapor, water spots will not be generated on the surface of the mold or the molded body, thus ensuring the molding effect.

[0043] Among them, the molded body is the workpiece that has been formed by extrusion through an extrusion die, but has not yet cooled.

[0044] In the above technical solution, to ensure the water inlet effect, a water supply pipe of the water supply device needs to be additionally connected to the liquid hole 242. This method is rather cumbersome. To solve this problem, please refer to [link / reference needed]. Figure 4 Specifically, the upper surface of the top cover 20 is provided with several water tanks 24, each water tank 24 having a connected liquid tank 241, and liquid holes 242 are provided inside the liquid tank 241.

[0045] A water tank 24 is opened on the surface of the top cover 20 to store water. The water source is guided to the position of the liquid hole 242 through the liquid tank 241. The water source of the liquid hole 242 then permeates to the cotton strip 23. Because the pores of the liquid hole 242 are small and the cotton strip 23 is there at the bottom, the water source flows out slowly. Therefore, when the airflow passes through, there will be no problem of water source draining out of the liquid hole 242 too quickly, causing the water source in the water tank 24 to be lost quickly. Moreover, the water tank 24 is directly opened on the top cover 20, which makes it easy to observe. When the water source is insufficient, the water source in the water tank 24 can be replenished in time.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
