Description

Technical Field

[0001] This utility model specifically relates to an assembly groove step extrusion tooling for a battery cover. Background Technology

[0002] The battery cover is a structural component on the top of the battery, which has multiple functions such as sealing, protection, and support. The terminal assembly slot is an opening or slot of a certain shape and size reserved on the battery cover for installing or fixing the terminal.

[0003] Existing electrode assembly slots are usually formed by one-step extrusion. However, after processing, the corners of the assembly slot steps cannot form right angles well, resulting in inclined surfaces at the corners, which affects the product qualification rate. In addition, in one-step extrusion, the punch corners are in a closed state, which makes it difficult for the punch to discharge oil and air during the extrusion process. To address this, we propose an extrusion tooling for the assembly slot steps of the battery cover. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for pressing the assembly groove steps of a battery cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for extruding the assembly groove steps of a battery cover, comprising:

[0006] Mounting base for connection to the stamping machine;

[0007] First stamping head;

[0008] The second stamping head is mounted side by side with the first stamping head on the lower surface of the mounting base, and a pressure plate is slidably sleeved on the outer side of the second stamping head, and the lower surface of the pressure plate has a downward protruding right-angle block.

[0009] Preferably, the second stamping head includes a stamping column and a stepped block, wherein the outer wall of the middle part of the stamping column extends outward to form a stepped block that presses down on the pressure plate, and the stamping column and the stepped block are integrally formed.

[0010] Preferably, the stamping column is the same shape and size as the first stamping head.

[0011] Preferably, the inner ends of the pressure plate are provided with guide holes, and the inner side of the guide holes has a guide rod connected to the mounting base.

[0012] Preferably, the right-angled block is annular, and the cross-section of the right-angled block is rectangular.

[0013] Preferably, the number of the second stamping head is equal to the number of the first stamping head.

[0014] Preferably, the cross-section of the first stamping head is "T" shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, consisting of a first punch head, a second punch head, a pressure plate, and a right-angle block, avoids the traditional one-step extrusion forming, where the cover plate assembly groove becomes an inclined surface after extrusion. This device uses two punch heads to extrude the cover plate in two steps, which facilitates the formation of a right angle. Furthermore, during the second extrusion step, the second punch head cooperates with the pressure plate to facilitate oil and air discharge during the extrusion process, resulting in good performance.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a battery cover plate assembly groove step extrusion tooling, comprising:

[0026] Mounting base 1 connected to the stamping machine;

[0027] First stamping head 2;

[0028] The second punch head 4 is installed side by side with the first punch head 2 on the lower surface of the mounting base 1, and the pressure plate 3 is slidably sleeved on the outer side of the second punch head 4, and the lower surface of the pressure plate 3 has a right-angle block 302 protruding downward.

[0029] This design allows for two-step stamping of the cover plate using the first stamping head 2 and the second stamping head 4. The second stamping step ensures the assembly groove is stamped into a right-angled step, preventing incomplete stamping in the first step where the stamped assembly groove is an inclined surface and cannot properly form a right angle. Figure 4 The image shows a slope formed by a single-step stamping process, while a right angle formed by a two-step stamping process using this device is shown below. Figure 5 As shown.

[0030] In this embodiment, preferably, the second stamping head 4 includes a stamping column 401 and a stepped block 402. The outer wall of the middle part of the stamping column 401 extends outward to form a stepped block 402 that presses down on the pressure plate 3. The stamping column 401 and the stepped block 402 are integrally formed, which facilitates better pressing down on the pressure plate 3 so that the right-angle block 302 contacts the battery cover plate for extrusion, making the corner of its assembly groove a right angle. Through two-step stamping, the stamping head can effectively discharge oil and air during the stamping process, avoiding the existing one-step stamping where the punch corner is in a closed state, which is not conducive to the discharge of oil and air during the extrusion process.

[0031] In this embodiment, preferably, the stamping column 401 and the first stamping head 2 are of the same shape and size.

[0032] In this embodiment, preferably, guide holes 301 are provided through both ends of the inner side of the pressure plate 3, and the inner side of the guide holes 301 has a guide rod connected to the mounting base 1, which facilitates the better movement of the pressure plate 3.

[0033] In this embodiment, preferably, the right-angle block 302 is annular and the cross-section of the right-angle block 302 is rectangular, which facilitates better stamping so that the corner of the cover plate assembly groove forms a right angle.

[0034] In this embodiment, preferably, the number of the second stamping head 4 is equal to that of the first stamping head 2, which facilitates stamping a greater number of assembly slots when the battery cover is transported by the conveyor.

[0035] In this embodiment, preferably, the cross-section of the first stamping head 2 is "T" shaped, which facilitates installation.

[0036] The working principle and usage process of this utility model are as follows: During stamping, multiple cover plates are conveyed by a conveyor from the first stamping head 2 to the second stamping head 4. The mounting base 1 drives the first stamping head 2 and the second stamping head 4 to move downward. The cover plate is stamped for the first time by the first stamping head 2. Then, after the cover plate moves below the second stamping head 4, it is stamped for the second time. The second stamping head 4 pushes the pressure plate 3 to move downward and contact the cover plate. Then, the second stamping head 4 continues to move downward and presses down on the pressure plate 3 through the step block 402. The right-angle block 302 on the lower surface of the pressure plate 3 makes the cover plate stamped to form a right-angle groove.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
