Description

Technical Field

[0001] This invention relates to the field of profile processing technology, and in particular to a stamping die for the notches of internal ribs in a profile structure. Background Technology

[0002] Currently, in the power battery systems of new energy vehicles, the lower battery housing is a key structural component. It not only supports the battery modules but also needs to provide installation space for auxiliary components such as the Battery Management System (BMS). Therefore, there are high requirements for the internal spatial layout of its frame. For example... Figure 1 and Figure 2 As shown in the figure, the beam frame 10 of the profile structure has an inner groove 11, in which several internal ribs 12 are arranged, and a shielding structure 13 is provided at the groove opening. The shielding structure 13 shields the internal ribs 12 along the opening direction of the inner groove 11. During the production process, in order to meet the design assembly requirements, specific notches 14 need to be machined on the internal ribs 12. However, since the internal ribs 12 are located in the inner groove 11 and there is a shielding structure 13 at the groove opening, the groove wall along the width direction of the profile ( Figure 2 The transverse shielding of the internal ribs 12 and the shielding structure 13 along the thickness direction of the profile (as shown) Figure 2 The longitudinal section shown obstructs the internal rib 12, making it impossible to machine the notch in the internal rib 12 using traditional stamping dies. Even with CNC machining, there are problems with toolpath interference and insufficient infeed space. Existing processes often use copper electrode electrical discharge machining (EDM) to form the notch in the internal rib of the profile structure. Although this can achieve high dimensional accuracy, the process has a long processing cycle and high cost, which is not conducive to large-scale industrial production. In addition, there is a technical solution to remove the obstructing structure to simplify the processing, but this method will change the structure of the beam frame, affecting the structural function of the product and the reliability of the overall assembly, thus having limitations in practical applications. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a stamping die for notching internal ribs in a profile structure. By setting a stamping part that can move into an inner groove, the notch of the internal ribs in the profile structure can be processed by stamping. While ensuring the design structural requirements and functions of the product, the processing method is relatively simple and low-cost, which is conducive to large-scale industrial production.

[0004] According to an embodiment of the present invention, a stamping die for notching internal ribs in a profile structure includes a pressure plate and a base. The pressure plate is disposed above the base and can move up and down relative to the base. The base is provided with a stamping die core and a support seat. The stamping die core is located between the pressure plate and the base and includes a punch that can move up and down. The punch has a stamping part. The support seat allows the beam frame of the profile structure to be placed in a state where its length direction is parallel to the front-back direction. The cross-sectional structure of the stamping part perpendicular to the front-back direction is "L"-shaped or inverted "L". The stamping part can move into the inner groove from the end opening along the length direction of the inner groove of the beam frame and correspond to the internal ribs in the inner groove. The pressure plate can drive the punch to move up and down, so that the stamping part stamps the internal ribs to stamp out notches on the internal ribs.

The beam is moved along the front-back direction, causing the stamping part to move from the end opening of the inner groove along its length direction into the inner groove and correspond to the internal ribs. The punch press drives the pressure plate to move vertically, thereby driving the punch to move vertically, causing the stamping part to stamp the internal ribs and create notches. This structure utilizes a stamping part with an "L"-shaped or inverted "L"-shaped cross-section. By manipulating the front-back movement of the beam of the profile structure, the stamping part can move vertically into the inner groove and correspond to the internal ribs. Notches in the internal ribs of the profile structure can be processed through stamping. While ensuring the design structural requirements and functions of the product, the processing method is relatively simple and low-cost, which is beneficial for large-scale industrial production.

The pressure plate can drive the movable plate to move in the up and down direction through the limiting guides.

[0011] According to some embodiments of the present invention, the stamping die core further includes an elastic element located below the movable plate and acting on the movable plate, causing the movable plate to have an upward tendency to move. The movable plate can move under the action of the elastic element to abut against the fixed plate, and the limiting guide can contact or separate from the pressure plate.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 A stamping die for internal rib notches in a profile structure includes a pressure plate 100 and a base 200. The pressure plate 100 is positioned above the base 200 and can move vertically relative to the base 200. The base 200 has a stamping die core and a support seat 210. The stamping die core is located between the pressure plate 100 and the base 200 and includes a vertically movable punch 330. The punch 330 has a stamping portion 331. The support seat 210 can accommodate the beam frame 10 of the profile structure along its length. The stamping part 331 is placed parallel to the front and back direction. The cross-sectional structure of the stamping part 331 perpendicular to the front and back direction is "L" shaped or inverted "L" shaped. The stamping part 331 can move into the inner groove 11 from the end opening along the length direction of the inner groove 11 of the beam frame 10 and correspond to the internal rib 12 in the inner groove 11. The pressure plate 100 can drive the punch 330 to move in the up and down direction, so that the stamping part 331 stamps the internal rib 12 to stamp out the notch 14 on the internal rib 12.

[0024] Understandably, such as Figures 1 to 6As shown, the beam frame 10 has a profile structure with an inner groove 11 arranged along its length. Two internal ribs 12 are arranged in the inner groove 11 and are spaced apart longitudinally. A shielding structure 13 is provided at the opening of the inner groove 11, which shields the internal ribs 12 along the opening direction of the inner groove 11. A stamping die is used to process the notches of the internal ribs 12 in the beam frame 10 of the profile structure. It includes a pressure plate 100 and a base 200. The base 200 is provided with a stamping die core and a bearing seat 210. Since there are two internal ribs 12 in the inner groove 11, two stamping die cores are provided and spaced apart in the left and right directions. Two bearing seats 210 are also provided and distributed corresponding to the two stamping die cores. Each stamping die core has a punch 330 that can move up and down. In use, the stamping die is placed on the punch press. The beam frame 10 of the profile structure is placed on the bearing seat 210 on the left side with its length direction parallel to the front-back direction. The beam frame 10 is moved in the front-back direction, so that the stamping part 331 of the stamping die core on the left side moves from the end opening of the inner groove 11 along the length direction into the inner groove 11 and aligns with one of the internal ribs 12 in the inner groove 11. The punch press drives the pressure plate 100 to move in the up-down direction, thereby driving the punch 330 to move upward. The beam frame 10 moves downwards, causing the stamping part 331 to stamp the internal rib 12, thereby stamping a notch 14 into the internal rib 12. Then, the beam frame 10 is transferred to the bearing seat 210 on the right side. The beam frame 10 is moved forward and backward, causing the stamping part 331 of the stamping die core on the right side to move from the end opening of the inner groove 11 along its length into the inner groove 11 and correspond to another internal rib 12 in the inner groove 11. The same stamping operation is performed to achieve notch processing on both internal ribs 12. This structure utilizes the stamping part 331, which has an "L" or inverted "L" shaped cross-section. By manipulating the forward and backward movement of the beam frame 10 of the profile structure, the stamping part 331 can move forward and backward into the inner groove 11 and correspond to the internal ribs 12. Notch processing of the internal ribs of the profile structure can be achieved through stamping. While ensuring the design structural requirements and functions of the product, the processing method is relatively simple and low-cost, which is conducive to large-scale industrial production.

[0025] In practical applications, the number of stamping die cores and bearing seats 210 can be set according to the number of internal ribs 12 in the inner groove 11. The specific structure of stamping die cores and bearing seats 210 will not be described in detail here, but will be explained in detail below.

[0026] In some embodiments, the stamping die core further includes a fixing plate 310, which is fixedly connected to the base 200. The fixing plate 310 is provided with two limiting members 340, which are respectively provided on the front and rear sides of the punch 330 and can both move into the inner groove 11 from the end opening along the length direction of the inner groove 11. Each limiting member 340 is provided with a limiting slot 341 that is adapted to the internal rib 12 so that the internal rib 12 can be inserted.

[0027] Understandably, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, each stamping die core includes two limiting members 340. Both limiting members 340 are fixedly mounted on the fixed plate 310 and each has a limiting slot 341 adapted to the internal rib 12. The fixed plate 310 is fixedly connected to the base 200. The two limiting members 340 are respectively located on the front and rear sides of the punch 330. In use, the beam frame 10 is moved along the front and rear direction so that the limiting members 340 and the stamping part 331 can move into the inner groove 11 from the end opening along the length direction. When the limiting members 340 move into the inner groove 11, the internal rib 12 is placed into the limiting slot 341 of the limiting members 340. The internal rib 12 is clamped by the limiting members 340 on both sides. Thus, when the stamping part 331 moves up and down to stamp, the possibility of deformation of the internal rib 12 on the front and rear sides can be reduced, achieving a better support and limiting effect and ensuring the reliability of notch processing. In practical applications, in addition to the above structure, an "L"-shaped or inverted "L"-shaped support structure can also be set to support the lower side of the internal rib 12, so as to reduce the possibility of deformation of the internal rib 12 on the front and rear sides of the stamping part 331 due to stamping, and ensure the stamping effect. The specific settings can be made according to the actual use needs.

[0028] In some embodiments, the stamping die core further includes a fixing plate 310, which is fixedly connected to the base 200. The fixing plate 310 is provided with a positioning protrusion 311 and a driver 350. The driver 350 drives a limiting push block 351 to move in the left and right direction, so that the limiting push block 351 can push the beam frame 10 to abut against the positioning protrusion 311.

[0029] Understandably, such as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the positioning protrusion 311 is integrally formed on the fixed plate 310. The driver 350 is disposed on the fixed plate 310 and drives the limiting push block 351. During stamping, the driver 350 drives the limiting push block 351 to move in the left and right direction, so that the limiting push block 351 can push the beam frame 10 to abut against the positioning protrusion 311. The limiting push block 351 and the positioning protrusion 311 clamp the beam frame 10 in the left and right direction, thereby fixing its position well and reducing the possibility of left and right deviation during stamping, ensuring the stamping effect. In practical applications, the driver 350 can be a cylinder, hydraulic cylinder, electric push rod, etc. The specific structure and setting position of the positioning protrusion 311 can be changed according to the specific structure of the beam frame 10, and are not limited here.

[0030] Furthermore, the pressure plate 100 is provided with a trigger 110, and the base 200 is provided with a corresponding switch 220. The switch 220 is electrically connected to the driver 350. When the pressure plate 100 moves closer to the base 200, the trigger 110 can trigger the switch 220, causing the driver 350 to drive the limit push block 351 to move and push the beam frame 10.

[0031] Understandably, such as Figure 4 As shown, the trigger 110 is located on the rear side of the pressure plate 100, and the switch 220 is correspondingly located on the rear side of the base 200. The switch 220 is electrically connected to the driver 350. When the pressure plate 100 moves closer to the base 200, the trigger 110 moves down and triggers the switch 220. The switch 220 feeds back an electrical signal, causing the driver 350 to drive the limit push block 351 to move and push against the beam frame 10, thereby controlling the driver 350. Its structure is simple and easy to use. In practical applications, the switch 220 can be a contact switch or an infrared sensor, etc., and can be set according to actual usage needs.

[0032] In some embodiments, a positioning plate 211 is provided on one side of the support 210 along the front-rear direction. The positioning plate 211 is used to position and abut against the beam frame 10 on the support 210. It is understood that, as Figure 3 , Figure 4 and Figure 7As shown, the positioning plate 211 is located on the rear side of the support seat 210. In use, the profile beam frame 10 is placed on the support seat 210 with its length direction parallel to the front-back direction. Then, the beam frame 10 on the support seat 210 is moved backward, causing the limiting member 340 and the stamping part 331 to move into the inner groove 11 from the rear end opening. The beam frame 10 moves backward until it abuts against the positioning plate 211, thereby achieving its front-back positioning. This helps ensure the accuracy of the notch processing position and facilitates use. In practical applications, the positioning plate 211 can be configured to move and adjust its position relative to the support seat 210, allowing the front-back position of the positioning plate 211 to be adjusted as needed. The specific structure of the positioning plate 211 can be set according to actual usage requirements.

[0033] In some embodiments, the stamping die core further includes a fixed plate 310 and a movable plate 320. The fixed plate 310 is fixedly connected to the base 200. The movable plate 320 is located below the fixed plate 310 and can move up and down relative to the fixed plate 310. The punch 330 is fixedly disposed on the movable plate 320. Limiting guide members 321 are provided on both the left and right sides of the movable plate 320. The limiting guide members 321 pass through the fixed plate 310 and correspond to the pressure plate 100. The pressure plate 100 can drive the movable plate 320 to move in the up and down direction through the limiting guide members 321.

[0034] Understandably, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the movable plate 320 is located below the fixed plate 310 and can move up and down relative to the fixed plate 310. The punch 330 is fixedly mounted on the movable plate 320. Two limiting guides 321 are fixedly mounted on the left and right sides of the movable plate 320 respectively and both pass through the fixed plate 310. In use, the pressure plate 100 moves downward and drives the movable plate 320 downward through the limiting guides 321, thereby driving the punch 330 downward to punch the internal ribs 12. Its structure is simple and can achieve a good limiting and guiding effect on the movable plate 320, ensuring the reliability of the movement of the punch 330 and facilitating its use. In practical applications, the specific structure of the fixed plate 310, the movable plate 320, and the limiting guides 321 can be set according to actual usage needs.

[0035] Furthermore, the stamping die core also includes an elastic element 360, which is located on the lower side of the movable plate 320 and acts on the movable plate 320, causing the movable plate 320 to have an upward tendency. The movable plate 320 can move to abut against the fixed plate 310 under the action of the elastic element 360, and the limiting guide 321 can contact or separate from the pressure plate 100.

[0036] Understandably, such as Figure 5 and Figure 6As shown, multiple elastic elements 360 are provided and located on the lower side of the movable plate 320. The upper end of the elastic element 360 abuts against the movable plate 320, and its lower end abuts against the base 200, thereby acting on the movable plate 320 and causing the movable plate 320 to tend to move upward. Before stamping, the limiting guide 321 separates from the pressure plate 100, and the movable plate 320 abuts against the lower side of the fixed plate 310 under the action of the elastic elements 360. During stamping, the pressure plate 100 moves downward and contacts the limiting guide 321, thereby pushing the movable plate 320 downward through the limiting guide 321, which in turn drives the punch 330 downward. After the stamping operation is completed, the pressure plate 100 moves upward to reset, and the movable plate 320 moves upward to reset under the action of the elastic elements 360. The above structure is simple and reasonable and easy to use. In practical applications, the specific number and distribution of elastic elements 360 can be set according to actual usage needs. In addition, they can also be connected to pressure plate 100 through limit guide element 321, thereby driving movable plate 320 to move up and down. The specific details can be changed according to actual usage needs.

[0037] In some embodiments, the support base 210 allows the beam frame 10 of the profile structure to be placed with the groove 11 facing downwards. The cross-sectional structure of the stamping part 331 perpendicular to the front-back direction is inverted "L" shape. The lower side of the fixing plate 310 is provided with a guide member 370 through which the movable plate 320 passes. The base 200 is provided with a dropping port 201. The guide member 370 is located below the stamping part 331 and is provided with a guide channel 371 corresponding to the dropping port 201.

[0038] Understandably, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, the lower side of the fixed plate 310 is provided with a guide member 370 through which the movable plate 320 passes. The base 200 is provided with a discharge port 201. The guide member 370 is located below the stamping part 331 and is provided with a guide channel 371 corresponding to the discharge port 201. The cross-sectional structure of the stamping part 331 perpendicular to the front and rear directions is inverted "L" shape. In use, the beam frame 10 is placed on the bearing seat 210 with the groove opening of the inner groove 11 facing down. After the internal ribs 12 are stamped, the waste material generated by the stamping process can fall from the groove opening of the inner groove 11 into the guide channel 371 below, and be guided by the guide channel 371 to the discharge port 201, where it falls and is collected for easy use. In practical applications, the beam frame 10 can also be placed on the bearing seat 210 with the groove opening of the inner groove 11 facing upwards. In this case, the cross-sectional structure of the stamping part 331 perpendicular to the front and rear directions needs to be set to be "L" shaped. The guide part 370 and the drop port 201 can be set according to the actual use needs.

[0039] In some embodiments, one of the pressure plate 100 and the base 200 is provided with a guide post 230, and the other is provided with a guide sleeve 120 that cooperates with the guide post 230. It is understood that, as Figure 3 and Figure 4 As shown, the guide post 230 is disposed on the base 200, and correspondingly, the guide sleeve 120 is disposed on the pressure plate 100. The guide post 230 and the guide sleeve 120 cooperate to guide the relative movement between the pressure plate 100 and the base 200, reducing the possibility of misalignment, ensuring reliable movement, and facilitating use. In practical applications, the guide post 230 can also be disposed on the pressure plate 100, in which case the guide sleeve 120 is disposed on the base 200. The specific configuration can be determined according to actual usage requirements.

[0040] In some embodiments, the pressure plate 100 and / or the base 200 are provided with a limiting post 130, which is located between the pressure plate 100 and the base 200 to limit the travel distance when the pressure plate 100 and the base 200 move closer together. It is understood that, as Figure 3 and Figure 4 As shown, both the pressure plate 100 and the base 200 are provided with limit posts 130. The limit posts 130 on the pressure plate 100 and the limit posts 130 on the base 200 are arranged opposite each other and have a vertical gap between them to limit the travel when the pressure plate 100 and the base 200 move closer together, reducing the possibility of the pressure plate 100 being excessively pressed down and ensuring reliability. In practical applications, the limit posts 130 can also be provided only on the pressure plate 100 or the base 200, and their specific structure and setting position can be set according to actual usage needs.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
