Description

Technical Field

[0001] This application relates to the field of anode plate technology, specifically to an anode plate for zinc-iron liquid tank batteries and its stamping die. Background Technology

[0002] In the production of zinc-iron liquid battery tanks, the anode plate is a key component, and its performance has a decisive impact on the overall performance of the battery. Traditional zinc-iron liquid battery anode plates have many shortcomings in structural design. Traditional anode plates often use a single material or simple splicing, which makes it difficult to balance their conductivity and corrosion resistance.

[0003] When the anode plate is composed of different components, the stability of the connection is poor. During the charging and discharging process of the battery, the stress generated by current conduction and chemical reaction can easily cause the connection to loosen or even separate, which greatly shortens the service life of the anode plate and thus affects the reliability and stability of the battery. In order to solve the above problems, an anode plate for zinc-iron liquid tank battery and its stamping die are proposed. Utility Model Content

[0040] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] Reference Figures 1 to 5This application provides an anode plate and its stamping die for a zinc-iron liquid electrolyte battery, including an anode plate 1 and a stamping die 2. The anode plate 1 includes a lead alloy plate 101 and a conductive head 102. The lead alloy plate 101 and the conductive head 102 are welded together. A plurality of protrusions are provided at intervals on the side of the conductive head 102 near the lead alloy plate 101. A plurality of grooves adapted to the protrusions are provided on the side of the conductive head 102 near the lead alloy plate 101. The stamping die 2 includes a lower die 201 and an upper die 202. The lower die 201 and the upper die 202 are adapted to each other. The lead alloy plate 101 has good corrosion resistance and certain electrochemical activity, enabling it to work stably in the battery electrolyte environment and ensuring the continuous electrochemical reaction. The conductive head 102 is made of highly conductive material, which can efficiently conduct electrons, reduce resistance, and improve the charging and discharging efficiency of the battery. The two are welded together, and multiple protrusions are spaced apart on the side of the conductive head 102 closest to the lead alloy plate 101, while an adaptation groove is provided on the side of the lead alloy plate 101. This increases the welding contact area, enhances the connection strength, prevents the two from separating due to stress during battery charging and discharging, extends the service life of the anode plate, and improves the working stability of the battery.

[0042] Reference Figure 3 and Figure 5 In one aspect of this embodiment, a stamping assembly 5 is provided inside the stamping die 2. The stamping assembly 5 includes a plurality of stamping blocks 501 spaced apart on the inner wall of the lower die 201, and a stamping plate 502 is fixedly connected to the bottom of the upper die 202.

[0043] The surface of the stamping die 2 is provided with a guide component 6. The guide component 6 includes a guide post 601 fixedly connected to the upper surface of the lower die 201, and a guide sleeve 602 fixedly connected to the surface of the upper die 202. The guide sleeve 602 is slidably connected to the guide post 601.

[0044] The bottom of the stamping die 2 is provided with a bottom component 3, which includes a bottom block 301 fixedly connected to the bottom of the lower die 201. A buffer pad 302 is adhered to the bottom of the bottom block 301. When the stamping operation is started, the upper die 202 moves downward under the action of the hydraulic mechanism 8. At this time, the stamping plate 502 fixedly connected to the bottom of the upper die 202 moves downward as well. At the same time, the lead alloy plate to be processed placed on the lower die 201 is subjected to the pressure of the stamping plate 502. Multiple stamping blocks 501 spaced apart on the inner wall of the lower die 201 cooperate with the stamping plate 502 to stamp and form the lead alloy plate into the required shape and structure. During the operation of the stamping die, when the upper die 202 moves up and down, the guide sleeve 602 moves along the guide fixedly connected to the upper surface of the lower die 201. The sliding of column 601 and the cooperation of guide column 601 and guide sleeve 602 provide precise guidance for the movement of upper die 202, ensuring that upper die 202 always maintains precise alignment with lower die 201 during the stamping process, avoiding stamping deviation caused by upper die 202 offset. When the stamping die is working, the bottom block 301 fixedly connected to the bottom of lower die 201 supports the entire die. The buffer pad 302 bonded to the bottom of bottom block 301 contacts the worktable surface on which the die is placed. The impact force generated during the stamping process is transmitted to the buffer pad 302 through bottom block 301, and the buffer pad 302 plays a role in buffering and shock absorption.

[0045] Reference Figure 4 and Figure 5 In one aspect of this embodiment, a hydraulic mechanism 8 is provided above the stamping die 2. The hydraulic mechanism 8 includes a work frame 801, and a hydraulic pump 802 is fixedly mounted on the surface of the work frame 801. The output end of the hydraulic pump 802 is connected to a hydraulic rod.

[0046] One end of the hydraulic rod is provided with a connecting component 7, which includes a connecting plate 701 fixedly connected to one end of the hydraulic rod, and a plurality of connecting bolts 702 are provided on the surface of the connecting plate 701.

[0047] The bottom of the work frame 801 is provided with a mounting assembly 4, which includes a mounting bracket 401 fixedly connected to the bottom of the work frame 801. The surface of the mounting bracket 401 has a through mounting hole 402. A hydraulic pump 802 is fixedly mounted on the surface of the work frame 801. When the hydraulic pump 802 is started, it pressurizes hydraulic oil, pushing a hydraulic rod to reciprocate linearly through its output end. The movement of the hydraulic rod drives the connected upper mold 202 to perform up-and-down punching actions. A connecting plate 701 is fixedly connected to one end of the hydraulic rod. Multiple connecting bolts 702 on the surface of the connecting plate 701 securely connect the hydraulic rod to the upper mold 202. When the hydraulic rod moves, the connecting assembly drives the upper mold 202 to move synchronously. The mounting bracket 401 is fixedly connected to the bottom of the work frame 801. The through mounting hole 402 on the surface of the mounting bracket 401 is used to fix the work frame 801 to a designated working position using bolts or other connecting components.

[0048] All electrical devices in this plan are powered by an external power source.

[0049] Working principle: During use, the lead alloy plate to be processed is placed in the lower mold 201, and the stamping operation is started. The hydraulic pump 802 is fixed on the work frame 801. After starting, pressurized hydraulic oil pushes the hydraulic rod to make reciprocating linear motion. The hydraulic rod drives the upper mold 202 to move downward through the connecting plate 701 and connecting bolt 702. At this time, the stamping plate 502 at the bottom of the upper mold 202 moves downward and cooperates with the stamping blocks 501 set at intervals on the inner wall of the lower mold 201 to stamp and form the lead alloy plate into the required shape and structure of the anode plate. During the stamping process, when the upper mold 202 moves up and down, the guide sleeve 602 slides along the guide post 601 on the upper surface of the lower mold 201 to ensure that the upper and lower molds are accurately aligned. The bottom block 301 at the bottom of the lower mold 201 supports the mold, and the buffer pad 302 at the bottom of the bottom block 301 buffers the impact force generated by the stamping. After the stamping is completed, the formed anode plate is removed and then welded to the conductive head 102 to make a complete anode plate for zinc-iron liquid tank battery.
