Description
Technical Field
[0001] This utility model relates to the field of explosion-proof sheet stamping die technology, and in particular to a lithium battery explosion-proof sheet micro-hole array stamping die. Background Technology
[0002] Explosion-proof discs are the core component of lithium battery safety systems. Their function is to release pressure by rupturing through pre-set weak areas (such as grooves or micropores) when the internal pressure of the battery rises abnormally, thus preventing the casing from exploding. Currently, mainstream explosion-proof discs are made of metal and are processed with explosion-proof grooves or micropore arrays through stamping. Compared with traditional grooves, micropore arrays have a more precise pressure release threshold control capability, and the burst pressure can be adjusted by the pore size and arrangement density.
[0003] Traditional stamping dies are usually rigidly connected to the workbench with bolts and nuts. When maintenance and repair of the stamping dies are required, it is difficult for operators to disassemble them, which is time-consuming and laborious, resulting in a longer maintenance and repair cycle and poor portability and practicality. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a lithium battery explosion-proof sheet micro-hole array stamping die, which aims to improve the problems of traditional stamping dies being difficult to disassemble, time-consuming and labor-intensive, resulting in prolonged mold maintenance and repair cycles, and low portability and practicality.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A micro-hole array stamping die for lithium battery explosion-proof sheet includes a worktable, a card holder fixedly connected to the upper surface of the worktable, a connecting component disposed inside the card holder, a first spring disposed inside the connecting component, a push plate disposed at the other end of the first spring, a buckle fixedly connected to the outside of the push plate, and a die body fixedly connected to the upper surface of the connecting component.
[0006] The above technical solution involves applying external force to the push plate to compress the first spring, causing the buckle to disengage from the card holder, thereby separating the connecting component from the card holder and ultimately disassembling the mold body from the worktable. This shortens maintenance and repair time and improves the portability and practicality of mold disassembly.
[0007] Preferably, the connecting assembly includes a first card plate, the outside of which is disposed inside the card holder, both sides of the card holder have limit grooves, the inside of the card holder has a first card slot, both sides of the first card plate are fixedly connected to limit plates, the outside of which are disposed inside the limit grooves, the outside of which is disposed inside the first card slot, the outside of which is disposed inside the first card slot, and the lower surface of the mold body is fixedly connected to the upper surface of the first card plate.
[0008] Preferably, the connecting assembly further includes a second card plate, the interior of which is disposed outside the card holder, and the card holder has second card slots formed inside both sides, with the exterior of the push plate disposed inside the second card slots.
[0009] Preferably, a microporous base is fixedly connected inside the mold body, a lubrication seat is fixedly connected outside the mold body, a closing component is provided on the upper surface of the lubrication seat, a closing plate is fixedly connected to the bottom of the closing component, a support platform is fixedly connected to the upper surface of the worktable, an electric push rod is fixedly connected to the top of the support platform, and a punching plate is fixedly connected to the output end of the electric push rod.
[0010] Preferably, the closing assembly includes a top seat, the lower surface of which is fixedly connected to the upper surface of the lubrication seat, a second spring is provided inside the top seat, a support column is provided inside the second spring, a pull ring is fixedly connected to one end of the support column, a push ring is fixedly connected to the outside of the support column, and the lower surface of the closing plate is fixedly connected to the bottom of the support column.
[0011] Preferably, the lubrication seat has a sliding groove inside, and the outside of the closing plate is slidably connected to the inside of the sliding groove.
[0012] Preferably, the outer side of the support column is slidably connected to the inside of the top seat, and the outer side of the push ring is slidably connected to the inside of the top seat.
[0013] Preferably, the outer surfaces of the push plate are slidably connected to the interiors of the first and second clamping plates, and the outer surfaces of the buckles are slidably connected to the interiors of the first and second clamping plates.
[0014] This utility model has the following beneficial effects: 1. In this utility model, an external force is applied to the push plate to compress the first spring, causing the buckle to disengage from the first or second slot, and the first or second plate to be removed from the base, thereby separating the mold body from the worktable and achieving the effect of facilitating quick disassembly of the mold body by the operator.
[0015] 2. In this utility model, pulling the pull ring causes the support column to move upward, and at the same time pushes the ring to compress the second spring, causing the closing plate to move upward along the sliding groove to open the outlet of the lubricating seat, and the lubricant flows into the stamping area; releasing the pull ring causes the second spring to return to its original position, pushes the ring to move the support column downward, and the closing plate closes the outlet, thereby achieving the effect of improving the accuracy of micro-hole stamping of the explosion-proof sheet.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0019] Reference Figures 1-3 An embodiment of this utility model is provided: a micro-hole array stamping mold for lithium battery explosion-proof sheet, including a worktable 1, a card seat 2 fixedly connected to the upper surface of the worktable 1, a connecting component 3 provided inside the card seat 2, a first spring 4 provided inside the connecting component 3, a push plate 5 provided at the other end of the first spring 4, a buckle 6 fixedly connected to the outside of the push plate 5, and a mold body 7 fixedly connected to the upper surface of the connecting component 3. Specifically, in this embodiment, the workbench 1 is the main body of the overall structure support, and the card seat 2 is used to cooperate with the connecting component 3 to realize the installation and fixation of the mold body 7. When the first spring 4 is in the natural state, it will generate a pushing force on the push plate 5, so that the push plate 5 drives the buckle 6 to be inserted into the interior of the card seat 2, thereby realizing the connection and fixation between the mold body 7 and the workbench 1.
[0020] Reference Figures 2-4 The connecting component 3 includes a first card plate 301, the outside of which is disposed inside the card holder 2. Limiting grooves 302 are provided on both sides of the card holder 2. A first card slot 303 is provided inside the card holder 2. Limiting plates 304 are fixedly connected to both sides of the first card plate 301. The outside of the limiting plates 304 is disposed inside the limiting grooves 302. The outside of the pushing plate 5 is disposed inside the first card slot 303. The lower surface of the mold body 7 is fixedly connected to the upper surface of the first card plate 301. Specifically, in this embodiment, the first card plate 301 is initially positioned by being embedded in the card holder 2. The limiting grooves 302 on both sides of the card holder 2 and the limiting plates 304 on both sides of the first card plate 301 are in a corresponding cooperation relationship. The limiting plates 304 are embedded in the limiting grooves 302 to limit the longitudinal displacement of the first card plate 301 in the card holder 2 and ensure the stability of the connection between the two. The first card groove 303 inside the card holder 2 is used to accommodate the push plate 5. The push plate 5 is inserted into the first card groove 303 under the action of the first spring 4 to achieve a tight connection between the first card plate 301 and the card holder 2. The mold body 7 is indirectly assembled and fixed to the worktable 1 by the fixed connection between the lower surface and the upper surface of the first card plate 301. When it is necessary to disassemble the mold body 7 for maintenance and repair, an external force is applied to the push plate 5 to compress the first spring 4, so that the push plate 5 drives the buckle 6 to disengage from the first card groove 303. At this time, the first card plate 301 can be taken out from the card holder 2 along the direction of the limiting groove 302 to achieve the separation of the mold body 7 from the worktable 1. Example
[0021] Reference Figure 4 and Figure 5 The connecting component 3 also includes a second card plate 305, the interior of which is disposed outside the card holder 2, and the card holder 2 has second card slots 306 inside both sides, and the exterior of the push plate 5 is disposed inside the second card slots 306. Specifically, in this embodiment, the second card plate 305 and the card seat 2 are externally nested structures. The inside of the second card plate 305 is fitted onto the outside of the card seat 2. The second card grooves 306 inside both sides of the card seat 2 are used to accommodate the push plate 5. The push plate 5 is inserted into the second card grooves 306 under the action of the first spring 4, which improves the stability of the connection between the mold body 7 and the worktable 1. When disassembly is required, the push plate 5 is disengaged from the second card grooves 306, and the second card plate 305 can be disengaged from the outside of the card seat 2 to achieve overall separation. This can facilitate the operator to quickly disassemble the mold body 7 and reduce the mold maintenance and repair cycle. Example

Specifically, in this embodiment, the microporous base 8 inside the mold body 7 provides a forming base for the microporous array stamping of the explosion-proof sheet, and the external lubrication seat 9 is used to deliver lubricant into the interior of the mold body 7. The support platform 13 is fixed on the worktable 1, and the electric push rod 14 can drive the punch plate 15 to move up and down to realize the stamping process of the material placed on the microporous base 8.

[0024] Working principle: When it is necessary to use this lithium battery explosion-proof sheet micro-hole array stamping die, firstly, the die body 7 is installed on the worktable 1 through the connecting component 3 and the card seat 2. Then, the explosion-proof sheet material to be processed is placed on the micro-hole base 8, the electric push rod 14 is started, and the punching plate 15 is driven to move downward to punch the material to form a micro-hole array. During the stamping process, if lubricant needs to be added, pull the pull ring 104 to move the support column 103 upward, push the ring 105 to compress the second spring 102, and cause the closing plate 11 to move upward along the sliding groove 12 to open the outlet of the lubricating seat 9, allowing the lubricant to flow into the stamping area; release the pull ring 104, the second spring 102 returns to its original position, push the ring 105 to move the support column 103 downward, and the closing plate 11 closes the outlet, thereby achieving the effect of improving the accuracy of the micro-hole stamping of the explosion-proof sheet; When maintenance and repair are required, an external force is applied to the push plate 5 to compress the first spring 4, causing the buckle 6 to disengage from the first slot 303 or the second slot 306, and the first card plate 301 or the second card plate 305 to be removed from the card seat 2, thereby separating the mold body 7 from the worktable 1, which can facilitate the operator to quickly disassemble the mold body 7.
