Description

Technical Field

[0001] The utility model relates to the technical field of battery accessory punching equipment, in particular to a punching needle device with a reinforced structure. Background Art

[0002] In the battery manufacturing industry, punching of battery cap accessories is an important process link. As a key component of the punching equipment, the performance of the punching needle device directly affects the quality and efficiency of the punching. The traditional punching needle device usually adopts a linear punching needle design. Although this design is simple, there are some problems in actual use. First, the top of the linear punching needle is often prone to breakage due to structural reasons. This is mainly because the punching needle needs to withstand greater impact and friction during the punching process, and the top of the linear punching needle lacks an effective reinforcement structure, resulting in insufficient strength and easy breakage. Secondly, the punching needle, as a wearing part, needs to be frequently repaired and replaced. However, the traditional punching needle device often adopts an integrated design, and the punching needle and the punching needle fixing seat cannot be easily disassembled, which brings inconvenience to the maintenance and replacement work. Therefore, in order to solve the above problems, improve the performance and service life of the punching needle device, and facilitate the maintenance and replacement of wearing parts, it is necessary to improve and innovate the existing punching needle device. The utility model comes into being just under such background, and aims to improve the strength and service life of the punching needle device and simplify the maintenance and replacement process by introducing a reinforced structure and a detachable design. Utility Model Content

[0003] The purpose of the utility model is to provide a punching needle device with a reinforced structure, which utilizes the reinforced part to increase the thickness and strength of the upper part of the punching needle, solves the problem that the top of the original straight punching needle is easy to break, and increases the service life of the punching needle. At the same time, the punching needle is detachable, which is convenient for the maintenance and replacement of wearing parts.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching needle device with a reinforced structure, comprising a punching needle fixing seat, on which a punching needle is detachably arranged, the punching needle comprising a needle body, a punching portion is arranged at the bottom of the needle body, a reinforcing portion is arranged at a position corresponding to the upper part of the punching portion on the inner side of the needle body, and the reinforcing portion is consistent in width with the punching portion.

[0005] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0006] Preferably, a plurality of punching needles are distributed in a ring shape on the punching needle fixing seat.

[0007] Preferably, a through hole is provided on the punch needle fixing seat corresponding to the position of the punch needle, the punching portion extends downward through the through hole, and a limiting boss is provided on the top of the needle body corresponding to the position above the through hole.

[0008] Preferably, positioning grooves are provided on both sides of the needle body along the length direction, and positioning ridges are provided on the inner wall of the through hole corresponding to the positioning grooves.

[0009] Preferably, the thickness of the reinforcement portion is consistent with the thickness of the punching portion, and the length of the reinforcement portion is not less than 2 / 3 of the overall length of the punching portion.

[0010] Preferably, the punching portion and the reinforcement portion are integrally formed.

[0011] Preferably, an arc-shaped transition portion is provided at the contact position between the bottom of the reinforcement portion and the punching portion.

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

[0013] The punching needle device with a reinforced structure of the utility model significantly improves the strength and service life of the punching needle device by introducing the reinforcement part design. The width of the reinforcement part is consistent with that of the punching part, which effectively increases the thickness of the upper part of the punching needle, thereby improving its anti-fracture ability. This design not only solves the problem that the top of the original straight punching needle is easy to break, but also significantly improves the overall stability of the punching needle, making the punching process more reliable. In addition, the detachable design of the punching needle makes maintenance and replacement more convenient. When the punching needle is worn or damaged, the user can easily remove the punching needle from the punching needle fixing seat for replacement or repair without disassembling the entire punching needle device. This not only improves the maintenance efficiency, but also reduces the maintenance cost. Furthermore, by optimizing the design scheme, such as annularly distributing multiple punching needles, setting through holes and limiting bosses, opening positioning grooves and setting positioning convex ridges, the punching needle device is more reasonable in structure and more stable and reliable in use. At the same time, the length and thickness design of the reinforcement part also fully consider the actual use requirements of the punching needle, ensuring the maximization of the reinforcement effect. Finally, the punching part and the reinforcement part are integrally formed to ensure the integrity and stability of the punching needle and avoid potential safety hazards caused by loose or falling parts. The arc-shaped transition part provided at the bottom of the reinforcement part in contact with the punching part further improves the strength and stability of the punching needle and extends the service life of the punching needle. In summary, the punching needle device with a reinforced structure of the utility model significantly improves the strength, stability and service life of the punching needle device through the introduction of the reinforcement part design and the detachable structure, as well as the implementation of a series of optimized technical solutions, while simplifying the maintenance and replacement process, reducing the cost of use, and having significant beneficial effects.
