[0001] This utility model relates to the field of battery nickel sheet forming mold technology, specifically to a double-sided burr-free battery nickel sheet forming mold. Background Technology

[0002] Nickel sheets are connecting pieces, tabs, leads, and current collectors used in battery production and assembly. They are primarily used for internal battery connections, acting as sensing connections to ensure normal battery operation. The quality and design of the nickel sheets directly affect battery safety and performance. A battery nickel sheet forming die is a mold used in cold stamping processes. By applying pressure on a press, the nickel sheet is separated or plastically deformed to obtain the desired parts or semi-finished products. This type of die is commonly used in the production of electronic and communication terminals, contact components, and various stainless steel stampings.

[0003] The existing technology has the following shortcomings: When the existing battery nickel sheet forming mold stamps the battery nickel sheet, burrs that bulge upwards or downwards are easily generated around the holes of the battery nickel sheet after stamping. This will affect the smoothness of the surface of the battery nickel sheet. Furthermore, when the operator handles the formed battery nickel sheet, the burrs will affect the operator's safety. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided burr-free battery nickel sheet forming mold. The surface of the stamped battery nickel sheet can be polished by the lower polishing roller and the upper polishing roller. At the same time, by adjusting the height of the upper polishing roller, the distance between the upper polishing roller and the lower polishing roller can be adjusted, so that battery nickel sheets of different thicknesses can be polished, thereby solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided burr-free battery nickel sheet forming mold, comprising a mold body, and further comprising:

[0006] The grinding mechanism is located on the outer wall of the discharge end of the mold body and is used to grind the stamped battery nickel sheet.

[0007] The grinding mechanism includes two fixed frames, which are respectively set at both ends of the discharge end of the mold body. A lower grinding roller is rotatably installed on the bottom inner side of the two fixed frames. A movable seat is provided on the top of the inner wall of each of the two fixed frames. An upper grinding roller is rotatably installed between the two movable seats. A first motor is provided at the opposite ends of the lower grinding roller and the upper grinding roller.

[0008] Preferably, the mold body includes a lower fixing plate, and a plurality of stamping holes are provided in the middle of the inner wall of the lower fixing plate. Guide rods are fixedly installed at the four corners of the top of the lower fixing plate.

[0009] Preferably, an upper fixing plate is fixedly sleeved on the outer side of the top of the four guide rods, and hydraulic cylinders are fixedly installed on both sides of the top of the upper fixing plate. The piston rods of the two hydraulic cylinders pass through the upper fixing plate and are fixedly installed with stamping plates.

[0010] Preferably, the two ends of the outer wall of one side of the lower fixing plate are respectively fixedly connected to two fixing frames, and a rotating shaft is rotatably installed on the inner side of the two fixing frames near the lower fixing plate.

[0011] Preferably, a second motor is provided at one end of the rotating shaft, and rotating gears are fixedly sleeved on the outer sides of both ends of the rotating shaft.

[0012] Preferably, each of the two movable seats has a movable rack fixedly installed on one side of its outer wall, and the two movable racks respectively mesh with two rotating gears.

[0013] Preferably, each of the two fixed frames has a movable groove on the top of its inner wall on the side away from the lower fixed plate, and the inner walls of the two movable grooves are respectively movably connected to the outer walls of the two movable seats.

[0014] Preferably, the top of the lower grinding roller is at the same height as the top surface of the punching hole, and the lateral length of the lower grinding roller is greater than the lateral dimension of the inner wall of the lower fixed plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The second motor causes the rotating shaft to rotate. Through the meshing action between the rotating gear and the movable rack, the height of the upper grinding roller can be adjusted, which in turn can adjust the distance between the lower grinding roller and the upper grinding roller, so as to adapt to the grinding work of battery nickel sheets of different thicknesses. Furthermore, the two first motors can drive the lower grinding roller and the upper grinding roller to grind and deburr the surface of the battery nickel sheet, which can ensure the smoothness of the surface of the battery nickel sheet and avoid the protruding burrs from causing injury to the operator.

[0017] 2. The movement of the movable seat can be limited by the movable groove, so that the movable seat remains stable during the height adjustment process, which in turn keeps the upper grinding roller stable during the height adjustment process. At the same time, the top of the lower grinding roller is at the same height as the top surface of the punch hole, so that the grinding mechanism can stably perform grinding operation on the battery nickel sheet.

[0026] This utility model provides, for example Figure 1 The double-sided burr-free battery nickel sheet forming mold shown includes a mold body 1, and further includes:

[0027] The grinding mechanism 2 is located on the outer wall of the discharge end of the mold body 1 and is used to grind the stamped battery nickel sheet.

[0028] To ensure the smoothness of the nickel plate surface in the battery, such as Figure 1-2 and Figure 4 As shown, the grinding mechanism 2 includes two fixed frames 201, which are respectively set at both ends of the discharge end of the mold body 1. A lower grinding roller 202 is rotatably installed on the bottom inner side of the two fixed frames 201. A movable seat 204 is provided on the top of the inner wall of each of the two fixed frames 201. An upper grinding roller 205 is rotatably installed between the two movable seats 204. A first motor 206 is provided on the opposite end of the lower grinding roller 202 and the upper grinding roller 205. The operation of the two first motors 206 enables the lower grinding roller 202 and the upper grinding roller 205 to perform grinding and deburring operation on the surface of the stamped battery nickel sheet, which can ensure the smoothness of the surface of the battery nickel sheet.

[0029] To facilitate the stamping and forming of battery nickel sheets, such as Figure 1-3As shown, the mold body 1 includes a lower fixed plate 101. Multiple stamping holes 102 are opened in the middle of the inner wall of the lower fixed plate 101. Guide rods 103 are fixedly installed at the four corners of the top of the lower fixed plate 101. An upper fixed plate 104 is fixedly sleeved on the outer side of the top of the four guide rods 103. Hydraulic cylinders 105 are fixedly installed on both sides of the top of the upper fixed plate 104. The piston rods of the two hydraulic cylinders 105 pass through the upper fixed plate 104 and are fixedly installed with stamping plates 106. The working of the hydraulic cylinders 105 causes the stamping plates 106 to cooperate with the stamping holes 102, so as to stamp and form the battery nickel sheet.

[0030] To facilitate the adjustment of the height of the upper grinding roller 205, such as Figure 2-4 As shown, the two ends of the outer wall of the lower fixed plate 101 are fixedly connected to two fixed brackets 201 respectively. A rotating shaft 208 is rotatably installed on the inner side of the two fixed brackets 201 near the lower fixed plate 101. A second motor 209 is provided at one end of the rotating shaft 208. Rotating gears 210 are fixedly sleeved on the outer sides of both ends of the rotating shaft 208. Movable racks 207 are fixedly installed on the outer wall of one side of the two movable seats 204. The two movable racks 207 mesh with the two rotating gears 210 respectively. When the second motor 209 works, the rotating shaft 208 rotates. Through the meshing action between the rotating gears 210 and the movable racks 207, the height of the movable seat 204 can be adjusted, thereby adjusting the distance between the lower grinding roller 202 and the upper grinding roller 205.

[0031] In order to ensure that the polishing mechanism 2 can stably polish the battery nickel sheet, such as Figure 2-4 As shown, each of the two fixed brackets 201 has a movable groove 203 on the top of its inner wall on the side away from the lower fixed plate 101. The inner walls of the two movable grooves 203 are movably connected to the outer walls of the two movable seats 204 respectively. The top of the lower grinding roller 202 is at the same height as the top surface of the punch hole 102. The lateral length of the lower grinding roller 202 is greater than the lateral dimension of the inner wall of the lower fixed plate 101. The movable groove 203 can limit the movement of the movable seat 204, so that the upper grinding roller 205 is stable during the height adjustment process. In this way, the lower grinding roller 202 and the upper grinding roller 205 can stably perform grinding and deburring operations on the battery nickel sheet.

[0032] During the stamping of the battery nickel sheet, the workpiece is conveyed to the top of the stamping hole 102 on the inner wall of the lower fixed plate 101. Then, two hydraulic cylinders 105 work to move the stamping plate 106 downwards. The stamping plate 106, in conjunction with the stamping hole 102, stamps the battery nickel sheet. As the battery nickel sheet is conveyed, it passes through the gap between the lower grinding roller 202 and the upper grinding roller 205. The second motor 209 then rotates the rotating shaft 208, causing the two rotating gears 210 to rotate. Through the meshing of the gears, the two movable racks 207 can move along the inner wall of the fixed frame 201, allowing the two movable seats 20... 4. The upper and lower grinding rollers 202 can move along the inner walls of the two movable grooves 203 respectively, thereby adjusting the height of the upper grinding roller 205. This allows the upper grinding roller 205 and the lower grinding roller 202 to adapt to the grinding of battery nickel sheets of different thicknesses. The two first motors 206 work to make the lower grinding roller 202 and the upper grinding roller 205 rotate, thereby fully grinding and deburring the surface of the battery nickel sheet. This ensures the smoothness of the battery nickel sheet surface and avoids the protruding burrs on the surface of the battery nickel sheet from causing injury to the operator. This embodiment specifically solves the problem in the prior art that the protruding burrs generated on the surface of the battery nickel sheet after stamping can cause injury to the operator.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
