Description

Technical Field

[0001] This utility model relates to the field of copper alloy processing technology, and in particular to an easy-to-level copper alloy processing stamping and forming device. Background Technology

[0002] Copper alloys are alloys composed of pure copper as the base material and one or more other elements added. They are mainly used to manufacture electrical equipment such as generators, busbars, cables, switchgear, and transformers, as well as heat-conducting equipment such as heat exchangers, pipes, and flat plate collectors for solar heating devices.

[0003] In existing copper alloy sheet stamping processes, the copper alloy sheet is usually placed on a lower die, and then an upper die is driven by a cylinder to stamp the copper alloy sheet in conjunction with the lower die. During the stamping process, the upper die applies a large pressure to the copper alloy sheet, causing it to deform. However, due to the internal stress of the copper alloy sheet during stamping, the outer edge of the stamped copper alloy sheet may warp, resulting in uneven edges. Furthermore, workers need to use tools to knock or pry the copper alloy parts when removing them, which can easily deform the stamped copper alloy parts and reduce the quality of the stamping process.

[0004] To address these issues, we propose an easily adjustable copper alloy processing and stamping device. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable copper alloy processing and stamping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easily adjustable copper alloy processing stamping forming device includes a frame, a lower die body, and an upper die body. The lower die body is installed on the frame table, and the upper die body is suspended above the lower die body via a support frame and a telescopic component. A die sleeve is movably fitted outside the lower die body. Guide rods are connected to the four corners of the die sleeve, and the guide rods slide through to the bottom of the frame table. The bottom of the four guide rods is mounted on the same flat plate, and a spring is connected between the flat plate and the frame table corresponding to each guide rod. Supports are installed on both sides of the bottom of the frame, and wear-resistant pads are connected to the upper surface of the support plates. When the upper die body presses down on the die sleeve until it contacts the frame table, the lower die body is completely exposed from the die sleeve.

[0008] In a further embodiment, when the lower surface of the mold base contacts the machine frame table, a wear-resistant pad is attached to the lower surface of the flat plate.

[0009] In a further embodiment, the mold base has a mold hole inside, and when the spring returns to its original position, the lower mold body is completely housed within the mold hole.

[0010] In a further embodiment, the bottom edge of the lower mold body is provided with a raised edge, the outer edge of which is chamfered to form a slope body one, and the inner top edge of the mold hole is chamfered to form a slope body two with the same slope as the slope body one.

[0011] In a further embodiment, when the lower surface of the mold base contacts the machine frame table surface, the first inclined body and the second inclined body are in contact, and the upper surface of the protruding edge is flush with the upper surface of the mold base.

[0012] In a further embodiment, a vertical telescopic member 2 is also installed at the bottom of the frame, and the output shaft end of the telescopic member 2 is connected to a push plate.

[0013] In a further embodiment, slide rods are symmetrically installed on both sides of the frame platform, and slide sleeves are slidably connected to the slide rods, which are fixedly connected to the upper mold body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a mold sleeve platform outside the upper mold body. When the lower and upper mold bodies are closed for stamping, the upper mold body fits flat against the mold sleeve platform, effectively reducing stress concentration on the lower mold body during stamping and preventing the edges of the formed part from warping. Simultaneously, when the upper mold body moves away from the lower mold body, the mold sleeve platform springs back under the elastic force of the spring, supporting the edge portion of the formed part to detach from the lower mold body. This not only facilitates subsequent material removal but also prevents edge deformation of the stamped copper alloy part, effectively improving the quality of the stamping process.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] 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.

[0024] Please see Figure 1-3 An easily adjustable copper alloy processing stamping forming device includes a frame 1, a lower die body 2, and an upper die body 3. The lower die body 2 is mounted on the table of the frame 1. A support frame 4 is fixed to the back of the frame 1. The support frame 4 consists of mutually perpendicular horizontal and vertical plates, with the horizontal plates extending above the lower die body 2. A vertical telescopic component 5 is fixedly mounted on the horizontal plate. The output shaft of the telescopic component 5 extends below the horizontal plate and is fixedly connected to the upper die body 3. Specifically, the telescopic component 5 can be, but is not limited to, a cylinder or a hydraulic cylinder, to drive the upper die body 3 to rise and fall and close with the lower die body 2. Corresponding to the protruding part of the lower die body 2, the upper die body 3 is provided with a recessed mold groove.

[0025] Specifically, slide rods 14 are symmetrically installed on both sides of the machine frame 1, and slide sleeves 15 are slidably connected to the slide rods 14. The slide sleeves 15 are fixedly connected to the upper mold body 3. When the upper mold body 3 is raised or lowered, the slide sleeves 15 are driven to slide along the slide rods 14 to limit the raising and lowering direction of the upper mold body 3 and prevent displacement or misalignment.

[0026] Please see Figure 1-3 To reduce stress concentration of the copper alloy on the lower mold body 2, a mold sleeve platform 6 is movably fitted outside the lower mold body 2. Guide rods 7 are connected to the four corners of the mold sleeve platform 6, and the guide rods 7 slide through to the bottom of the frame 1. The bottom of the four guide rods 7 is mounted on the same flat plate 8, and a spring 9 is connected to each guide rod 7 between the flat plate 8 and the frame 1. The spring 9 is fitted onto the portion of the guide rod 7 that extends below the frame 1. Specifically, a mold hole 61 is opened inside the mold sleeve platform 6, allowing the lower mold body 2 to move within the mold hole 61. When the upper mold body 3 presses down, it first contacts the mold sleeve platform 6. The pressing down of the mold sleeve platform 6 causes the guide rods 7 to slide down, and simultaneously the springs 9 extend. When the upper mold body 3 presses down on the mold sleeve platform 6 until it contacts the frame 1, the lower mold body 2 is completely exposed. The mold base 6 is used to achieve mold closing with the upper mold body 3. The upper mold body 3 and the mold base 6 are flat and close to each other, so that the edge of the copper alloy forming part is pressed flat. This can effectively reduce the stress concentration on the lower mold body 2 during stamping, and thus prevent the edge of the forming part from warping. At the same time, when the upper mold body 3 moves away from the lower mold body 2, the mold base 6 rebounds under the elastic force of the spring 9, rises relative to the lower mold body 2, and supports the edge of the forming part to detach from the lower mold body 2. This not only facilitates subsequent material removal, but also prevents the problem of edge deformation of the stamped copper alloy part. Specifically, when the spring 9 returns to its original position, the lower mold body 2 is completely housed in the mold hole 61, so as to prevent the lower mold body 2 from being exposed in the mold hole 61 and affecting the flatness of the copper alloy sheet to be stamped.

[0027] For further details, please refer to Figure 4 The lower mold body 2 has a raised edge 21 around its bottom edge. The outer edge of the raised edge 21 is chamfered to form a slope 22. The inner top edge of the mold hole 61 is chamfered to form a slope 62 with the same slope as the slope 22. When the lower surface of the mold base 6 contacts the table surface of the frame 1, the slope 22 and the slope 62 fit together. The upper surface of the raised edge 21 is flush with the upper surface of the mold base 6. This allows the pressure on the upper mold body 3 to be distributed through the contact between the slope 22 and the slope 62, so that the pressure can be transferred to the table surface of the frame 1 through the mold base 6, thus maintaining the balance and stability of the device.

[0028] Please see Figure 1-3 Both sides of the bottom of the frame 1 are equipped with support platforms 10, and the upper surface of the support platform 10 is connected with a wear-resistant pad 11. When the lower surface of the mold sleeve platform 6 contacts the table surface of the frame 1, the lower surface of the plate 8 is in contact with the wear-resistant pad 11. The pressure on the mold sleeve platform 6 can also be transmitted to the support platform 10 through the guide rod 7 and the plate 8, so as to distribute part of the pressure on the mold sleeve platform 6 through the support platform 10, and further maintain the balance and stability of the device.

[0029] Please see Figure 1-3The bottom of the frame 1 is also equipped with a vertical telescopic component 2 12, and the output shaft end of the telescopic component 2 12 is connected to the push plate 13. Specifically, the telescopic component 1 5 can be, but is not limited to, a cylinder or a hydraulic cylinder. When the telescopic component 2 12 is retracted to its shortest length, the push plate 13 is lower than the height of the wear-resistant pad 11, so that when the mold is closed and pressed, the plate 8 will not press on the push plate 13, reducing the pressure damage to the telescopic component 2 12 and the push plate 13. When the spring 9 has a poor reset effect, when the telescopic component 2 12 drives the push plate 13 to rise, it can push the plate 8 to move upward, thereby helping the mold sleeve table 6 to reset quickly.
