Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a stamping and forming structure for an automotive aluminum alloy battery box. Background Technology

[0002] As a critical protective component of the battery system, the quality and performance of automotive aluminum alloy battery boxes directly affect the safety and lifespan of the battery. Aluminum alloys, with their advantages of low density, high strength, and corrosion resistance, have become the preferred material for battery box manufacturing.

[0003] In the existing technology, the stamping and forming structure of automotive aluminum alloy battery boxes uses an integral design for the stamping and forming mold. The key forming components of the mold, such as the punch and die, are tightly integrated with the mold base, making it difficult to separate and adjust. The mold cavity size, punch and die clearance, and other parameters are all precisely calculated and processed according to a single material thickness. Once battery boxes with different material thicknesses are produced, the overall mold cannot adapt to the new material characteristics and forming requirements, and the whole mold must be replaced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing stamping and forming structures for automotive aluminum alloy battery boxes, where the stamping and forming molds are designed as a single piece. Therefore, this invention proposes a stamping and forming structure for automotive aluminum alloy battery boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stamping and forming structure for an automotive aluminum alloy battery box, comprising a base plate and a hydraulic device, wherein a fixing device is provided on one side of the base plate, the fixing device comprising a lower die base and a die cavity, one side of the lower die base being fixedly connected to the base plate, and both sides of the die cavity being fixedly connected to fixing frames, two internal threaded rings being fixedly connected to the inner side of the fixing frames, the internal threads of the internal threaded rings being connected to first bolts, the arc surfaces of the four first bolts being threadedly connected to the lower die base, four guide rods being fixedly connected to one side of the lower die base, the arc surfaces of the four guide rods being slidably connected to an upper die base, one side of the upper die base being fixedly connected to the hydraulic device, and two second bolts being threadedly connected to one side of the upper die base, the arc surfaces of the second bolts being threadedly connected to internal threaded blocks, a fixing plate being fixedly connected to the outer side of the internal threaded blocks, and a punch being fixedly connected to the side of the two fixing plates that are close to each other.

[0006] The effect achieved by the above components is that the first bolt rotates to unscrew the lower die holder to eliminate the limitation on the die cavity, and the second bolt rotates to unscrew the internal thread block to eliminate the limitation on the punch.

[0007] Preferably, two anti-fooling rods are slidably connected to one side of the fixing plate, and one end of the four anti-fooling rods is fixedly connected to the upper mold base.

[0008] The effect achieved by the above-mentioned components is to prevent incorrect assembly of the fixing plate by the anti-fool rod.

[0009] Preferably, a T-shaped groove is provided on one side of the lower mold base.

[0010] The effect achieved by the above components is that the T-shaped groove is opened on the lower mold base.

[0011] Preferably, a T-shaped plate is slidably connected inside the T-shaped groove, and one side of the T-shaped plate is fixedly connected to the die.

[0012] The effect achieved by the above components is that the movement of the die causes the T-shaped plate to slide within the T-groove.

[0013] Preferably, a collection device is provided on one side of the base plate. The collection device includes a collection box, one side of which is fixedly connected to the base plate, and two T-shaped rods are slidably connected to one side of the collection box.

[0017] Preferably, a telescopic rod is fixedly connected to one side of the support plate, and a top plate is fixedly connected to the output ends of the two telescopic rods.

[0018] The effect achieved by the above components is that the movement of the top plate causes the output end of the telescopic rod to extend or retract.

[0019] Preferably, a spring is fitted onto the arc surface of the telescopic rod, and one end of the spring is fixedly connected to the support plate.

[0020] The effect achieved by the above components is that the elastic force of the spring makes the extension and retraction process of the telescopic rod smoother.

[0021] Preferably, a pressure plate is fixedly connected to one side of the top plate.

[0022] The effect achieved by the above components is that the movement of the top plate drives the adjustment of the pressure plate position.

After complete separation, the die limit lock is released, and the die is moved horizontally to complete the separation and replacement. Then, the second bolt is rotated to unscrew the internal thread block, and after the punch limit is released, it is moved vertically downward to separate and replace the upper mold base. Through the fixing device, the problem of traditional stamping and forming structures for automotive aluminum alloy battery boxes, where the stamping and forming mold adopts an integral design and the key forming components such as the punch and die are tightly integrated with the mold base, making it difficult to disassemble and adjust, is solved.

[0025] In this invention, a collection device is used to collect the aluminum alloy scrap after trimming. The scrap is then placed into a collection box, thus completing the collection of the aluminum alloy scrap. This collection device solves the problem of the inability to properly collect and place the trimmed scrap after the stamping and forming of traditional automotive aluminum alloy battery boxes.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a stamping and forming structure for an automotive aluminum alloy battery box, including a base plate 1 and a hydraulic device 4, a fixing device 2 on one side of the base plate 1, and a collecting device 3 on one side of the base plate 1.

[0032] The following section will describe the specific setup and function of the fixing device 2 and the collecting device 3.

[0033] Reference Figure 2 and Figure 3 As shown in this embodiment: the fixing device 2 includes a lower mold base 201 and a die 205. One side of the lower mold base 201 is fixedly connected to the base plate 1. Both sides of the die 205 are fixedly connected to a fixing frame 204. The inner side of the fixing frame 204 is fixedly connected to two internal threaded rings 203. The internal threads of the internal threaded rings 203 are connected to the first bolts 202. The arc surfaces of the four first bolts 202 are threadedly connected to the lower mold base 201. One side of the lower mold base 201 is fixedly connected to four guide rods 206. The arc surfaces of the four guide rods 206 are slidably connected to an upper mold base 207. One side of the upper mold base 207 is fixedly connected to a hydraulic device 4. One side of the upper mold base 207 is threadedly connected to two second bolts 208. The arc surfaces of the second bolts 208 are threadedly connected to internal threaded blocks 209. The outer side of the internal threaded blocks 209 is fixedly connected to a fixing plate 210. The side of the two fixing plates 210 that are close to each other is fixedly connected to a punch 214. The first bolt 202 rotates to unscrew the lower mold base 201, eliminating the limitation on the die 205, and the second bolt 208 rotates to unscrew the internal thread block 209, eliminating the limitation on the punch 214. Two anti-fooling rods 211 are slidably connected to one side of the fixing plate 210, and one end of each anti-fooling rod 211 is fixedly connected to the upper mold base 207. This achieves the effect of the anti-fooling rods 211 preventing incorrect assembly of the fixing plate 210. A T-slot 212 is provided on one side of the lower mold base 201. This achieves the effect of the T-slot 212 being formed on the lower mold base 201. A T-plate 213 is slidably connected inside the T-slot 212, and one side of the T-plate 213 is fixedly connected to the die 205. This achieves the effect of the die 205 moving, causing the T-plate 213 to slide within the T-slot 212.

[0034] Reference Figure 4 As shown in this embodiment: the collection device 3 includes a collection box 31, one side of which is fixedly connected to the base plate 1. Two T-shaped rods 32 are slidably connected to one side of the collection box 31, achieving the effect of the T-shaped rods 32 sliding on the collection box 31. Side plates 33 are fixedly connected to one side of the two T-shaped rods 32, and support plates 34 are fixedly connected to both sides of the collection box 31, achieving the effect of the support plates 34 being fixed to the collection box 31 and the side plates 33 being fixed to the T-shaped rods 32. Telescopic rods 35 are fixedly connected to one side of the support plates 34, and top plates 37 are fixedly connected to the output ends of the two telescopic rods 35, achieving the effect of the top plate 37 moving to extend or retract the output ends of the telescopic rods 35. A spring 36 is fitted on the arc surface of the telescopic rod 35, and one end of the spring 36 is fixedly connected to the support plate 34, achieving the effect of the elastic force of the spring 36 making the extension and retraction process of the telescopic rod 35 smoother. A pressure plate 38 is fixedly connected to one side of the top plate 37. This achieves the effect of moving the top plate 37 to adjust the position of the pressure plate 38.

[0035] Working principle: Using the fixing device 2, when mold replacement is required, the operator first rotates the first bolt 202, gradually loosening the lower mold base 201 under force. Once the first bolt 202 is completely disengaged from the lower mold base 201, the limiting lock on the die 205 is released. At this point, the die 205 is slowly moved horizontally, allowing the T-shaped plate 213 at the bottom of the die 205 to slide smoothly within the T-shaped groove 212. This movement continues until the die 205, along with the T-shaped plate 213, completely disengages from the T-shaped groove 212, completing the separation of the die 205 from the lower mold base 201, thus enabling the replacement of the die 205. Next, rotate the second bolt 208 to gradually unscrew the internal thread block 209 after applying force. When the second bolt 208 is completely disengaged from the internal thread block 209, the limit of the punch 214 is released. At this time, the punch 214 can be slowly moved downward in the vertical direction until the punch 214 is completely separated from the upper die holder 207, thereby replacing the punch 214. Through the fixing device 2, the problem of the traditional stamping and forming structure of automotive aluminum alloy battery boxes is solved. The stamping and forming die adopts an integral design, and the key forming components such as the punch 214 and the die 205 are tightly integrated with the die holder, making it difficult to disassemble and adjust.

[0036] When collecting the trimmed aluminum alloy scrap using the collection device 3, the operator first takes the trimmed aluminum alloy scrap into the collection box 31 to complete the collection. When a certain amount of aluminum alloy scrap accumulates inside the collection box 31, pressure is applied to the top plate 37. Under pressure, the top plate 37 drives the pressure plate 38 to move towards the collection box 31. At this time, the return spring 36 at the output end of the telescopic rod 35 is in a contracted state. As the pressure plate 38 continues to move, it squeezes the aluminum alloy scrap inside the collection box 31, and the aluminum alloy scrap is continuously subjected to force. After extrusion forming, the pressure on the top plate 37 is stopped. At this time, the spring 36 rebounds, causing the top plate 37 to drive the pressure plate 38 back to its original position. Then, the side plate 33 is pulled away from the collection box 31, so that the T-shaped rod 32 slides on the collection box 31, thereby eliminating the side obstruction of the collection box 31. The formed aluminum alloy waste can then be taken out from the collection box 31. Through the collection device 3, the problem of the trimmed waste being unable to be properly collected and placed after the stamping and forming of the traditional automotive aluminum alloy battery box is solved.
