Description

Technical Field

[0001] This utility model relates to the field of shearing mold technology, and more specifically, to a shearing upper mold with positioning function. Background Technology

[0002] The rapid development of new energy vehicles has placed higher demands on battery performance and safety. As a key structure protecting the core components of the battery, the processing precision, surface quality and structural strength of the battery casing are of paramount importance. The processing quality of the battery casing is the foundation for ensuring the overall performance of the battery pack.

[0003] Currently, in the rotary cutting process of the battery casing of new energy vehicles, since the rotary cutting blade is a single blade, if the gap between the concave template and the rotary cutting blade is made just right, scratches will occur on the surface when the concave template is pressed down. If the gap is too large, burrs and outward turning phenomena are likely to occur at the corners of the battery casing. This not only affects the appearance quality of the casing, but may also reduce its structural strength and assembly performance. Utility Model Content

[0004] In view of this, the present invention provides a shearing upper die with positioning function, which aims to solve the above-mentioned technical problems.

[0005] This utility model discloses a shearing upper die with positioning function, including an upper die support assembly and a shearing assembly. At least a portion of the shearing assembly is connected to the upper die support assembly, and the remaining portion of the shearing assembly is provided with a shearing guide push block through an elastic structure. When the remaining portion of the shearing assembly extends into the housing, the shearing guide push block contacts the inner wall of the housing.

[0006] Preferably, at least two shear guide push blocks are symmetrically arranged.

[0007] Preferably, the remaining portion of the shearing assembly is provided with two shearing guide push blocks along the first axis X direction and the second axis Y direction, respectively.

[0008] Preferably, the shear guide push block has an arc surface on the side facing the housing.

[0009] Preferably, the elastic structure includes a plurality of elastic elements, and a plurality of elastic elements are provided between each of the shearing guide push blocks and the remaining portion of the shearing assembly.

[0010] Preferably, the shearing assembly includes a shearing chip, the shearing guide pusher is disposed on the shearing chip, and the shearing chip is provided with a clearance groove for accommodating at least a portion of the shearing guide pusher.

[0011] Preferably, the shearing chip has a plurality of receiving holes 1 for accommodating the elastic element 1 on both sides along the first axis X direction, and the shearing chip has a plurality of receiving holes 2 for accommodating the elastic element 1 on both sides along the second axis Y direction; the plurality of receiving holes 1 are arranged along the first axis X direction, and the plurality of receiving holes 2 are arranged along the third axis Z direction.

[0012] Preferably, the shearing assembly further includes a punch holder, a punch base, and a shearing punch; at least a portion of the punch base extends into the mounting hole of the punch holder; the punch base and the shearing punch are connected by an I-shaped connector; the other side of the shearing punch connected to the punch base is connected to the shearing chip.

[0013] Preferably, the punch holder has limiting plates on opposite sides, and the shearing chip protrudes beyond the two limiting plates.

[0014] Preferably, the upper mold support assembly includes an upper template, an upper mold base, and an upper pad. The upper mold base is fixedly disposed below the upper template. The upper mold base has an upper top block and a mold handle fixedly connected inside, and at least a portion of the mold handle extends into the upper pad. The upper pad is connected to the punch fixing seat.

[0015] Compared with existing technologies, the advantages of this invention are that by setting a shearing guide push block, the shell opening can be guided during the shearing and pressing process of the upper die, making the shearing more precise and the height of the battery shell more stable. Furthermore, the traditional one-piece punch base is complex to process and costly. This application divides the punch base into two parts, consisting of a punch base and a shearing punch. The shearing punch can be made of better materials, with its hardness and toughness improved separately. Furthermore, the limiting plate in this application is directly fixed to the punch fixing seat, which provides a more stable connection and a larger support surface compared to the traditional setting of limiting posts, effectively reducing errors caused by the offset and runout of the entire upper die and improving shearing accuracy.

Therefore, they should not be construed as limitations on this application.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Example 1, combined with Figure 1 and Figure 2As shown, this embodiment provides a shearing upper die with positioning function, including an upper die support assembly and a shearing assembly. At least a portion of the shearing assembly is connected to the upper die support assembly, and the remaining portion of the shearing assembly is provided with a shearing guide push block 13 through an elastic structure. When the remaining portion of the shearing assembly extends into the housing, the shearing guide push block 13 contacts the inner wall of the housing.

[0023] Specifically, in this embodiment, the upper shearing die can be mounted on the punch press table. The punch press table drives the upper shearing die to move downwards. During the downward movement of the upper shearing die, the shearing assembly extends into the opening of the battery casing and presses the battery casing into the lower die that matches the upper shearing die. Since the shearing assembly is provided with a shearing guide push block 13, the shearing guide push block 13 contacts the inner wall of the battery casing under the action of the elastic structure, thereby guiding the battery casing and preventing the battery casing from shifting during the pressing process, making the shearing more precise and the height dimension of the battery casing more stable.

[0024] Furthermore, during the shearing process, the elastic structure exerts a pushing force on the shearing guide pusher 13, which keeps the battery casing in a stable position during the shearing process, plays a role in cutting and pressing the material, improves the flatness of the cut, reduces burrs caused by shaking of the battery casing opening, reduces indentations caused by burrs, and improves the yield of the battery casing.

[0025] Preferably, at least two shear guide push blocks 13 are symmetrically arranged.

[0026] Specifically, when two shear guide push blocks 13 are symmetrically arranged, the inner cavity of the battery casing is preferably circular.

[0027] Preferably, the remaining part of the shearing assembly is provided with two shearing guide push blocks 13 along the first axis X direction and the second axis Y direction, respectively.

[0028] Specifically, when two shear guide push blocks 13 are respectively arranged along the first axis X direction and the second axis Y direction, the inner cavity of the battery casing is preferably rectangular.

[0029] Preferred, combined Figure 4 As shown, the shear guide push block 13 has an arc surface 131 on the side facing the housing.

[0030] Specifically, the arc surface 131 effectively reduces the friction between the shear guide push block 13 and the inner wall of the battery casing, thereby reducing wear and extending the service life of the shear guide push block 13. At the same time, the arc surface 131 can further improve the accuracy of guidance, ensuring that the shear assembly extends more smoothly into the battery casing and avoiding offset problems caused by uneven contact.

[0031] Preferably, the elastic structure includes a plurality of elastic elements 12, and a plurality of elastic elements 12 are provided between each shear guide push block 13 and the remaining part of the shear assembly.

[0032] Specifically, the elastic element 12 is, for example, a spring. The elastic element 12 provides thrust to each shear guide push block 13, and each shear guide push block 13 can also be bolted to the remainder of the shear assembly.

[0033] Preferred, combined Figure 3 As shown, the shearing assembly includes a shearing chip 11, a shearing guide pusher 13 disposed on the shearing chip 11, and the shearing chip 11 is provided with a relief groove 113 for accommodating at least part of the shearing guide pusher 13.

[0034] Specifically, the clearance groove 113 is configured to provide guidance for the shear guide push block 13. At the same time, the clearance groove 113 can also effectively limit the movement range of the shear guide push block 13, ensuring that it runs within the predetermined trajectory, thereby improving the stability and reliability of the overall shearing process.

[0035] Preferably, the shearing chip 11 is provided with a plurality of receiving holes 111 for accommodating the elastic element 12 on both sides along the first axis X direction, and the shearing chip 11 is provided with a plurality of receiving holes 112 for accommodating the elastic element 12 on both sides along the second axis Y direction; the plurality of receiving holes 111 are arranged along the first axis X direction, and the plurality of receiving holes 112 are arranged along the third axis Z direction.

[0036] Specifically, the first axis X is perpendicular to the second axis Y, and the third axis Z is perpendicular to the plane formed by the first axis X and the second axis Y.

[0037] Specifically, receiving hole 111 is located at the bottom of the clearance groove 113 at the corresponding position, and receiving hole 2 112 is located at the bottom of the clearance groove 113 at the corresponding position.

[0038] Specifically, the arrangement of receiving holes 111 and 112 makes the installation of elastic component 12 more stable, which not only enhances the compactness of the overall structure, but also reduces the risk of displacement caused by external force interference when located at the bottom of the clearance groove 113, further ensuring the accuracy and consistency of the shearing operation.

[0039] Preferably, the shearing assembly further includes a punch holder 6, a punch base 8, and a shearing punch 10; at least a portion of the punch base 8 extends into the mounting hole 61 of the punch holder 6; the punch base 8 and the shearing punch 10 are connected by an I-shaped connector 9; the other side of the shearing punch 10 connected to the punch base 8 is connected to the shearing chip 11.

[0040] Specifically, an I-shaped connector 9 is provided between the punch base 8 and the shearing punch 10, and the I-shaped connector 9 is connected to the punch base 8 and the shearing punch 10 respectively by bolts.

[0041] Specifically, the separate design of the punch base 8 and the shearing punch 10 allows the shearing punch 10 to be made of better materials, improving its hardness and toughness, and reducing production costs and processing difficulty.

[0042] Preferably, the punch holder 6 has limiting plates 7 on opposite sides, and the shearing chip 11 protrudes beyond the two limiting plates 7.

[0043] Specifically, the setting of the limit plate 7 increases the support contact area, improves the stability of the entire mold, and reduces the offset and jump of the mold.

[0044] Preferably, the upper mold support assembly includes an upper template 1, an upper mold base 2, and an upper pad 5. The upper mold base 2 is fixedly disposed below the upper template 1. The upper mold base 2 is provided with an upper top block 3 and a mold handle 4 fixedly connected inside, and at least a portion of the mold handle 4 extends into the upper pad 5. The upper pad 5 is connected to the punch fixing seat 6.

[0045] Specifically, the upper mold base 2 has a central hole 21, and the upper top block 3 and the mold handle 4 are engaged in the central hole 21.

[0046] Specifically, several fasteners, such as bolts, are provided between the upper mold base 2 and the upper top block 3.

[0047] Specifically, the fasteners make the connection between the upper die holder 2 and the upper ejector block 3 more secure, effectively preventing loosening caused by long-term use or high-frequency operation. In addition, the connection between the die shank 4 and the upper pad 5 further enhances the overall structural coordination, making the force transmission more uniform, thereby improving the stability and efficiency of the shearing process.

[0048] It is understood that the specific working steps of a shearing upper die with positioning function in this embodiment are as follows: Attach and fix the upper template 1 to the punch press table; Connect the upper mold base 2 to the upper template 1; First, fix the upper ejector block 3 and the mold handle 4 with bolts, then insert them into the center hole 21 of the upper mold base 2, and then fix the upper ejector block 3 with bolts through the side bolt holes of the upper mold base 2. The mold handle 4 is also fixed because it is connected to the upper ejector block 3. Connect the upper pad 5 to the mold handle 4 together; Connect the punch holder 6 to the upper pad 5; Install the two limiting plates 7 on the punch fixing seat 6; Insert the punch base 8 into the mounting hole 61 of the punch fixing seat 6 for installation; Install the shearing chip 11 onto the shearing punch 10; Install the shearing punch 10 on the punch base 8; Place the elastic element 12 into the receiving hole 111 and the receiving hole 112 of the shearing chip 11, and then push the shearing guide push block 13 into the corresponding clearance groove 113 and fix it to the shearing chip 11 with bolts.

[0049] During operation, the assembled upper shearing die presses the battery casing into the corresponding lower die. The pushing force of the shearing guide pusher 13 keeps the battery casing opening in a guided state. During the shearing process, the pushing force acts as a cutting edge clamping agent, improving the flatness of the cut, reducing burrs caused by casing opening movement, reducing indentations caused by burrs, and improving the battery casing yield. Then, when the limiting plate 7 contacts the lower die, it further supports the stability of the entire mold, reducing the offset and runout of the upper and lower dies.
