Description

Technical Field

[0001] This utility model belongs to the technical field of battery box shell processing equipment, specifically relating to an adaptive stamping device for battery box shells. Background Technology

[0002] In the production of sheet metal parts for battery box housings, sometimes it is necessary to stamp and form structures with local protrusions. These structures are mostly used to expand the space on the battery box to install cooling or other electrical systems. The specific size of the local protrusions varies depending on the battery box model. Therefore, stamping dies for protrusions of various sizes are often made and formed separately. However, since the usage of related products is usually not large, the production cost of separate mold forming is generally high due to the constraints of the mold, which further reduces the competitiveness of the products. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Example

[0019] Please see Figure 1 An adaptive stamping device for battery box housing includes an upper press platform 1 and a stamping seat 2 located below the upper press platform. The upper press platform is provided with a liftable stamping main die 3, and multiple stamping secondary dies 4 are also movably installed on the upper press platform. The cross-sectional dimensions of the stamping secondary dies are adapted to the cross-sectional dimensions of the stamping main die, and the stamping secondary dies can be spliced ​​or separated from the stamping main die by electromagnetic attraction.

[0020] The stamping base 2 is provided with a forming cavity 21. The size of the forming cavity is adjustable to adapt to the main stamping mold that is spliced ​​with any number of stamping sub-dies.

[0021] Multiple adjusting blocks 22 are fitted to the inner wall of the forming cavity 21. The number and size of the adjusting blocks are adapted to the size of the number of stamping sub-dies. The height of each adjusting block is adjustable so that the top surface of the adjusting block is coplanar with the top or bottom surface of the forming cavity. The number of adjusting blocks coplanar with the top surface of the forming cavity is negatively correlated with the number of stamping sub-dies spliced ​​on the stamping main die.

[0022] The upper pressing platform 1 is also fixedly provided with multiple moving rails 11, and several retractable second lifting rods 13 are slidably installed on the moving rails. The stamping sub-dies are fixed at the end of the second lifting rod away from the moving rails, and the stamping sub-dies on each moving rail are located on the same straight line perpendicular to one side of the stamping main die.

[0023] A connecting protrusion 5 is fixedly provided on the stamping sub-die 4. A mating groove 51 is provided on the side of the stamping main die 3 and the connecting surface of the stamping sub-die and the adjacent stamping sub-die connecting protrusion. The mating groove is adapted to the connecting protrusion. The connecting protrusion and the mating groove have a strong magnetic attraction when energized.

[0024] The upper press table 1 is provided with at least one retractable first lifting rod 12. The two ends of the first lifting rod are respectively connected and fixed to the upper press table and the stamping main die. The stamping main die moves up and down through the first lifting rod.

[0025] The stamping base 2 is also provided with multiple retractable third lifting rods 23. One end of the third lifting rod is fixed inside the stamping base, and the other end is connected and fixed to the adjusting block.

[0026] The stamping base 2 is hollow, and a forming platform 211 is fixedly installed in the center of the stamping base. A stop block 212 is provided on the periphery of the stamping base. The top surface of the stop block and the top surface of the stamping base are on the same horizontal plane. The adjusting block is located on the periphery of the forming platform. The top surface of the forming platform and the side wall of the adjusting block or the side wall of the stop block enclose the forming cavity.

[0027] The adaptive stamping device for the battery box housing in this embodiment works by combining the size change of the protruding part of the sheet metal housing with the number of stamping sub-dies and adjusting blocks spliced ​​with the stamping main die. This allows the size of the die body and forming cavity used for stamping to be changed to match the size of the stamped product. The unused stamping sub-dies are contracted and fixed under the action of their corresponding second lifting rods. Among the adjusting blocks, the number and position of the adjusting blocks that match the stamping sub-dies spliced ​​on the stamping main die are lowered into the stamping seat under the action of the third lifting rod. The top of these adjusting blocks is on the same plane as the top surface of the forming table (i.e., the bottom surface of the forming cavity), and there is no gap between the adjusting blocks and the forming table (the two are connected by a smooth surface. Due to the influence of processing accuracy, no gap mainly refers to reducing the gap spacing that may affect the stamping). After the adjustment of the stamping sub-dies and adjusting blocks is completed, the stamping main die and the corresponding stamping sub-dies are pressed down under the synchronous drive of the first lifting rod and some of the corresponding second lifting rods, and the product stamping is completed in conjunction with the forming cavity.

[0028] During the forming process, the second lifting rod is difficult to extend and ensure the stability of the stamping sub-die. The stamping sub-die needs to be precisely spliced ​​with the stamping main die to prevent product deformation caused by splicing gaps. At this time, the connecting protrusions and mating grooves with strong magnetic force after being energized are used to assist the connection. During splicing, the stamping sub-dies and the stamping main die are attracted and connected by magnetic force, which can effectively reduce the generation of gaps. As for the energization method of the connecting protrusions and mating grooves, conductive slide rails can be used with power lines connected in the first or second lifting rods to conduct electricity, or the power supply can be directly built into the stamping main die or stamping sub-die and powered by remote control or wireless switch. There are many specific methods, all of which are conventional technical means, and will not be elaborated here.

[0029] The beneficial effects of this utility model are: it can adapt to various specifications of battery box shell sheet metal parts with partial stamping protrusions with a single device, saving the mold opening expenditure of conventional molds and reducing mold opening costs. At the same time, it provides an electromagnetic attraction connection solution for the unstable characteristics of splicing molds, which can effectively reduce the gaps between splicing molds and improve splicing stability and molding quality.

[0030] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
