Description

Technical Field

[0001] This utility model relates to the field of cold heading molds for battery terminals, and in particular to a cold heading mold for battery terminals of new energy vehicles. Background Technology

[0002] In the field of new energy vehicles, battery terminals are an important component of battery packs, and their processing quality directly affects the performance and safety of the battery. Currently, most battery terminals are processed using cold heading, a new metal pressure processing technology with minimal or no cutting. Cold heading utilizes the plastic deformation of metal under external force, using a mold to redistribute and transfer the metal volume, thereby forming the required parts or blanks.

[0003] In cold heading, a method of upper and lower mold closing is usually used, with the raw material being formed in the forming cavity between the upper and lower molds. In order to print polarity markings or specification information on the battery terminals, corresponding protrusions need to be set in the mold; however, due to the wide variety of information that needs to be printed, the traditional fixed mold design is not flexible enough when changing, which not only increases production costs but also reduces production efficiency.

[0004] Based on this, in order to optimize the applicability of existing molds, we propose a cold heading mold for new energy vehicle battery terminals. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lack of flexibility in the design of fixed molds when changing them, which not only increases production costs, but also to propose a cold heading mold for battery terminals of new energy vehicles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cold heading mold for battery terminals of new energy vehicles, including an upper mold base with an upper mold and a lower mold base with a lower mold;

[0008] Forming grooves are provided on the opposite surfaces of the upper mold and the lower mold;

[0009] A lifting plate is movably connected to the inner side of the lower mold base via an elastic component. Several connecting columns are detachably connected to the top of the lifting plate. The connecting columns pass through several forming grooves of the lower mold, and an identification plate is fixedly installed at the top of each connecting column.

[0010] Furthermore, the elastic component includes a plurality of guide rods fixedly installed on the inner side of the lower mold base, and the lifting plate is slidably connected between the plurality of guide rods, wherein a compression spring is placed between the inner side of the lower mold base and the lifting plate, and the compression spring is sleeved on the outer side of the guide rods.

[0011] Furthermore, a plurality of rectangular holes are provided on the end face of the lifting plate, and a rectangular part is formed at the bottom of the connecting column, the rectangular part being inserted into the inner side of the rectangular holes;

[0012] The inner side of the lifting plate has a limiting assembly for fixing the connecting column.

[0013] Furthermore, the limiting component includes a push block and a plurality of limiting plates fixed to the side end of the push block;

[0014] The inner side of the lifting plate is provided with an installation cavity that connects to its outer side and a number of sliding grooves. The sliding grooves are connected to a number of rectangular holes in the same row, and the sliding grooves are connected to the installation cavity. The push block slides in the installation cavity by means of a spring, and the number of limiting plates slide sequentially in the number of sliding grooves.

[0015] Furthermore, a notch is provided on the side of the rectangular portion, the side of the limiting plate is engaged in the notch, and an avoidance opening is provided on the end face of the limiting plate to avoid the rectangular portion.

[0016] Furthermore, the guide rod matrix has four rods, and positioning glass beads are embedded on the outer sides of two diagonally distributed guide rods. The positioning glass beads and the lifting plate stop each other.

[0017] The present invention provides a cold heading mold for new energy vehicle battery terminals, which has the following advantages: By employing a detachable marking plate, information from the marking plate can be pressed onto the surface of the terminal during cold heading, such as positive or negative electrode markings, or product specifications. Secondly, the connecting column and the lifting plate are detachably connected, allowing for the replacement of different marking plates according to the actual marking requirements.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 As an embodiment of this utility model, a cold heading forming mold for battery terminals of new energy vehicles is disclosed. Specifically, the forming mold includes an upper mold base 2 on which an upper mold 1 is installed and a lower mold base 4 on which a lower mold 3 is installed. The lower mold base 4 is fixed on the machine base, while the upper mold base 2 is used to connect to the driving device of the cold heading equipment, thereby driving the upper mold base 2 to move the upper mold 1 up and down.

[0026] The upper mold 1 and the lower mold 3 are provided with forming grooves 11 on their opposite surfaces. During processing, the forming material of the pole is placed in the forming groove 11 of the lower mold 3. When the upper mold 1 and the lower mold 3 are closed, the pole is formed by extrusion through the two forming grooves 11 to complete the cold heading operation.

[0027] In this embodiment, a lifting plate 6 is movably connected to the inner side of the lower mold base 4 via an elastic component 5. Several connecting posts 7 are detachably connected to the top of the lifting plate 6. The connecting posts 7 respectively penetrate into several forming grooves 11 of the lower mold 3. A label plate 8 is fixedly installed at the top of the connecting posts 7. In some optional embodiments, the end face of the label plate 8 can be provided with a protrusion to be imprinted, such as a positive or negative electrode mark, or information such as product specifications and models. In this embodiment, the connecting posts 7 and the lifting plate 6 are detachably connected. Therefore, in actual operation, different label plates 8 can be replaced according to the actual imprinting requirements.

[0028] In some embodiments, the elastic component 5 of the present invention includes a plurality of guide rods 51 fixedly installed on the inner side of the lower mold base 4, and the lifting plate 6 is slidably connected between the plurality of guide rods 51. A compression spring 52 is placed between the inner side of the lower mold base 4 and the lifting plate 6, and the compression spring 52 is sleeved on the outer side of the guide rods 51.

[0029] In other words, the lifting plate 6 described in this embodiment adopts a liftable structure design. Its purpose is that when the raw material is under pressure during the mold closing process, it can move downward against the marking plate 8. In this way, the entire lifting plate 6 begins to move downward until the raw material is formed inside the two forming grooves 11. At the same time, the marking plate 8 imprints the information on its end face onto the pole. After cold heading, the upper mold 1 and the lower mold 3 separate. At this time, under the push of the compression spring 52, the lifting plate 6 moves upward to reset. At the same time, the marking plate 8 moves upward to lift the above-mentioned forming pole. This also achieves the purpose of facilitating the demolding of the pole, thereby further improving the operational convenience of cold heading.

[0030] Furthermore, in this embodiment, the lifting plate 6 has several rectangular holes 61 on its end face, and the bottom of the connecting column 7 is formed with a rectangular part 71, which is inserted into the inside of the rectangular hole 61.

[0031] The inner side of the lifting plate 6 has a limiting component 9 for fixing the connecting column 7.

[0032] In some preferred embodiments, the limiting component 9 of this utility model includes a push block 91 and a plurality of limiting plates 92 fixed to the side end of the push block 91, wherein the plurality of limiting plates 92 and the push block 91 are vertically connected.

[0033] The inner side of the lifting plate 6 is provided with a mounting cavity 62 that connects to its outer side and a plurality of sliding grooves 63. Of course, in this embodiment, the lifting plate 6 can be composed of two plates combined together, so as to facilitate the processing of each groove and the assembly of other parts. The sliding grooves 63 are connected to a plurality of rectangular holes 61 in the same row, and the sliding grooves 63 are connected to the mounting cavity 62. The push block 91 slides in the mounting cavity 62 by means of a spring 93. The spring 93 is used to reset the push block 91. A plurality of limiting plates 92 slide sequentially in a plurality of sliding grooves 63.

[0034] Based on the above embodiments, in this embodiment, the rectangular portion 71 has a notch 72 on its side, the side of the limiting plate 92 is engaged in the notch 72, and the end face of the limiting plate 92 is also provided with an avoidance opening 94 to avoid the rectangular portion 71.

[0035] Specifically, when the connecting post 7 is fixed, the side of the limiting plate 92 is engaged in the notch 72 of its rectangular part 71. At this time, the connecting post 7 is circumferentially locked and its vertical position is fixed. When it is necessary to disassemble and replace the connecting post 7, the pushing block 91 mentioned above can be pressed to drive multiple limiting plates 92 to move synchronously. When the clearance opening 94 on the side of the limiting plate 92 is aligned with the notch 72, the connecting post 7 can be pulled upward so that the rectangular part 71 of the connecting post 7 passes through the clearance opening 94 and the connecting post 7 can be pulled out to complete the disassembly.

[0036] It should be noted that in this embodiment, there are four guide rods 51 in a matrix distribution. The outer sides of the two diagonally distributed guide rods 51 are also fitted with positioning glass beads 53. The positioning glass beads 53 and the lifting plate 6 stop each other. In normal working condition, the upward movement of the lifting plate 6 can be limited by the positioning glass beads 53. When it is necessary to disassemble the connecting column 7, the telescopic end of the positioning glass beads 53 can be pressed and the lifting plate 6 can be slid to the upper side of the positioning glass beads 53. At this time, the telescopic end of the positioning glass beads 53 can stop the lower side of the lifting plate 6 for support. Since the label plate 8 is at a high position after the lifting plate 6 is raised, the label plate 8 can be easily taken from above, thereby improving the ease of disassembly and assembly of the label plate 8.

[0037] In summary, by employing a detachable label plate 8, the information on the label plate 8 can be pressed onto the surface of the electrode post during cold heading. This information includes positive or negative electrode markings, product specifications, and other details. Furthermore, the connecting post 7 and the lifting plate 6 are detachably connected. Therefore, in actual operation, different label plates 8 can be replaced according to the actual imprinting requirements. In addition, the lifting plate 6 is designed to be movable. During mold separation, the label plate 8 moves upward to lift the formed electrode post, thus facilitating the demolding of the electrode post and further improving the ease of operation of cold heading.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
