Description

Technical Field

[0001] This utility model relates to the field of perforation technology, and in particular to a punching device for battery box plates. Background Technology

[0002] During the sheet metal processing, appropriate holes are punched on the battery box sheet metal according to different usage requirements, so that the battery box sheet metal can be used to meet the punching requirements of different settings.

[0003] Most existing battery box sheet punching devices can perform quick punching operations by conveniently positioning the battery box sheet. However, most of these devices cannot provide circumferential pressure to limit the punching position on the battery box sheet, resulting in bending or deformation during punching. This leads to secondary repairs and ultimately inefficiencies in battery box sheet processing. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching device for battery box panels, comprising a punching machine body, a hydraulic telescopic rod fixedly installed on the surface of the punching machine body, a punching mechanism fixedly installed at the end of the hydraulic telescopic rod away from the punching machine body, a positioning cover slidably installed on the surface of the punching mechanism, an external groove formed on the surface of the punching mechanism, an external sliding plate slidably installed on the inner wall of the external groove on the punching mechanism, an external sliding rod slidably installed on the inner side of the external sliding plate, both ends of the external sliding rod being fixedly installed on the inner side of the punching mechanism, and an elastic component slidably sleeved on the surface of the external sliding rod, the two ends of the elastic component respectively abutting against the inner side of the punching mechanism and the surface of the external sliding plate.

[0006] Preferably, a cotton pad is bonded to the surface of the positioning cover, and the surface of the cotton pad has a groove.

[0007] Preferably, the inner side of the punching machine body is provided with a built-in groove, the surface of the punching machine body is provided with a limiting groove that communicates with the built-in groove, and the outer side of the punching machine body is provided with an auxiliary groove that communicates with the limiting groove.

[0008] Preferably, the surface of the punching machine body is provided with a collection groove that communicates with the punching opening at the built-in groove, and a collection box is slidably installed on the inner wall of the collection groove on the punching machine body.

[0009] Preferably, a movable guide wheel is rotatably installed on the inner side of the collection box, and a discharge plate is welded to the inner side of the punching machine body.

[0010] Preferably, the positioning cover is located outside the punching mechanism.

[0011] Preferably, the discharge plate is inclined inside the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The battery box plate punching device can make more full contact with the battery box plate through the positioning cover, and the cotton pad on the positioning cover can increase the frictional resistance of contact with the battery box plate. The groove on the cotton pad is also to increase the friction coefficient between the positioning cover and the battery box plate, thereby ensuring the firmness of the compression and limiting between the positioning cover and the battery box plate. This method ensures that when the battery box plate is punched, the periphery of the punching of the battery box plate has the effect of limiting and pressing, thereby improving the disadvantage of the battery box plate being deviated and deformed during punching. Therefore, it improves the overall stability of the battery box plate during punching and reduces the disadvantage of bending or deformation at the punching point, which would require secondary repair of the battery box plate.

[0014] (2) The battery box plate punching device collects the waste material from punching the battery box plate by setting a collection box inside the punching machine body. The discharge plate set at an incline inside the collection box can discharge the collected waste material in a directional manner, so that the waste material has a certain central discharge effect when collected inside the collection box, thus ensuring that the waste material inside the collection box has a good containment effect.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a punching device for battery box panels, including a punching machine body 1. The inner side of the punching machine body 1 is provided with a built-in groove 2, and the surface of the punching machine body 1 is provided with a limiting groove 3 that communicates with the built-in groove 2. The outer side of the punching machine body 1 is provided with an auxiliary groove 4 that communicates with the limiting groove 3. The built-in groove 2 on the punching machine body 1 is used for punching the battery box panel, while the limiting groove 3 on the punching machine body 1 is used for placing and limiting the battery box panel. The auxiliary groove 4 on the punching machine body 1 is used to assist the operator in picking up and placing the battery box panel.

[0026] Furthermore, a collection groove 5 is provided on the surface of the punching machine body 1, which communicates with the punching opening at the built-in groove 2. A collection box 6 is slidably installed on the inner wall of the collection groove 5 on the punching machine body 1. A moving guide wheel 7 is rotatably installed on the inner side of the collection box 6. A discharge plate 8 is welded and installed on the inner side of the punching machine body 1. The discharge plate 8 is inclined inside the collection box 6. By setting the collection box 6 inside the punching machine body 1, the waste material of the battery box plate punched at the punching machine body 1 is collected. The discharge plate 8 inclined inside the collection box 6 can discharge the collected waste material in a directional manner, so that the waste material has a certain central discharge effect when collected inside the collection box 6, thereby ensuring that the collection box 6 has a good capacity when collecting waste material.

[0027] Furthermore, a hydraulic telescopic rod 9 is fixedly installed on the surface of the punching machine body 1. A punching mechanism 10 is fixedly installed at the end of the hydraulic telescopic rod 9 away from the punching machine body 1. A positioning cover 11 is slidably installed on the surface of the punching mechanism 10. An external groove 12 is formed on the surface of the punching mechanism 10. An external sliding plate 13 is slidably installed on the inner wall of the external groove 12 on the punching mechanism 10. An external sliding rod 14 is slidably installed on the inner side of the external sliding plate 13. Both ends of the external sliding rod 14 are fixedly installed on the inner side of the punching mechanism 10. An elastic component 15 is slidably sleeved on the surface of the external sliding rod 14. Both ends of the elastic component 15 abut against the inner side of the punching mechanism 10 and the surface of the external sliding plate 13, respectively. A cotton pad 16 is adhesively installed on the surface of the positioning cover 11. A groove 17 is formed on the surface of the cotton pad 16.

[0028] Specifically, when punching holes in the battery box sheet, the hydraulic telescopic rod 9 drives the punching mechanism 10 to descend. The punching machine body 1, the hydraulic telescopic rod 9, and the punching mechanism 10 are all existing publicly available technical structures. Since the programming control unit and auxiliary power structure of the punching machine body 1, the hydraulic telescopic rod 9, and the punching mechanism 10 are all electrically connected, they will not be elaborated upon here. As the punching mechanism 10 descends, the positioning cover 11 first contacts the battery box sheet. The punching mechanism 10 continues to descend until the positioning cover 11 no longer slides on the surface of the punching mechanism 10. Then, the positioning cover 11 forms a compression limit at the required punching location, and the punching mechanism 10 performs the punching operation on the battery box sheet. The positioning cover 11, acting as a pressure limiter on the surface of the punching mechanism 10, then performs the punching operation on the battery box sheet. The sliding adjustment of the surface allows the positioning cover 11 to make more full contact with the battery box plate. The cotton pad 16 on the positioning cover 11 can increase the frictional resistance between the positioning cover 11 and the battery box plate. The groove 17 on the cotton pad 16 is also to increase the friction coefficient between the positioning cover 11 and the battery box plate, thereby ensuring the firmness of the compression and limiting between the positioning cover 11 and the battery box plate. This method ensures that when the battery box plate is punched, the circumference of the punched hole has a limiting and pressing effect, thereby improving the disadvantages of displacement and deformation of the battery box plate during punching. Therefore, it improves the overall stability of the battery box plate during punching and reduces the disadvantages of bending or deformation at the punching point, which would require secondary repair of the battery box plate.

[0029] Working principle: A battery box panel punching device, when it is necessary to punch the battery box panel, the hydraulic telescopic rod 9 drives the punching mechanism 10 to descend until the positioning cover 11 contacts the battery box panel first. Then the punching mechanism 10 continues to descend until the positioning cover 11 no longer slides on the surface of the punching mechanism 10. Then the positioning cover 11 forms a compression limit on the position to be punched, and the punching mechanism 10 performs the punching operation on the battery box panel.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
