Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a stamping and forming structure for sheet metal processing. Background Technology

[0002] Stamping and forming in sheet metal processing is an important manufacturing process widely used in various industries such as automobiles, home appliances, electronic equipment, and machinery. With the development of modern manufacturing, the requirements for product precision and production efficiency are constantly increasing, and stamping and forming, as a highly efficient metal forming technology, is gradually gaining attention. Stamping and forming mainly involves applying pressure to metal sheets using dies, causing plastic deformation to obtain the desired shape and size. This process has advantages such as high production efficiency, high material utilization, and good product consistency, enabling the large-scale production of complex-shaped parts in a short time. Furthermore, stamping and forming can be combined with other processing techniques, such as welding and assembly, to form complete production lines, further improving production efficiency and reducing costs. With the development of automation and intelligent technologies, modern stamping and forming processes are gradually transforming towards intelligent manufacturing, adopting CNC technology and robotic systems to achieve higher precision and flexibility. This not only improves production efficiency but also makes personalized customization and small-batch production possible.

[0003] However, in the existing technology, when the sheet metal parts are stamped and formed by stamping equipment, if the sheet metal parts require high precision in shape or the material is elastic and the quality of one-time forming cannot be guaranteed, the sheet metal parts usually need to be stamped a second time to achieve the purpose of shaping. This not only increases the difficulty of stamping, but also affects the precision of shaping, resulting in errors in the dimensions of the sheet metal parts. Therefore, there is an urgent need for a stamping and shaping structure for sheet metal parts processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stamping and forming structure for sheet metal processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping and forming structure for sheet metal processing includes a mold body composed of an upper clamping plate, a stop plate, a lower die base, and a stripper plate stacked together. A stamping rod is vertically slidably inserted into the upper clamping plate and the stop plate, and a linkage plate is fixedly connected inside the lower die base. An extrusion plate is slidably connected to the inner side of the linkage plate, and a workpiece is inserted between the two extrusion plates. The bottom of the workpiece is connected to the stripper plate through a snap-fit ​​assembly.

[0007] During operation, the stamping rod presses downwards, adhering to the top of the extrusion plate and causing the extrusion plate to move horizontally within the linkage plate. This causes the two extrusion plates to extrude the workpiece located in the middle, thereby completing the shaping of the workpiece. After shaping, the workpiece is removed from the mold body by the stripper plate.

[0008] As a further embodiment of this utility model: the bottom inclined surface of the stamping rod is adapted to the outer inclined surface of the extrusion plate, and the bottom side of the stamping rod is in close contact with the top vertical surface of the extrusion plate.

[0009] As a further improvement of this invention, a spring is fixedly connected between the two extrusion plates.

[0010] As a further embodiment of this utility model: the snap-fit ​​assembly includes a connecting seat, a snap block, a snap ring, and an L-shaped snap hole, and the connecting seat is fixedly connected to the bottom of the workpiece.

[0011] As a further embodiment of this utility model: the two locking blocks are respectively welded to the outer circumference of the connecting seat, and the retaining ring is fixedly connected to the bottom outer wall of the stripper plate.

[0012] As a further improvement of this utility model: the L-shaped card holes are respectively opened on both sides of the circumference of the card ring, and the two L-shaped card holes are adapted to the two card blocks.

[0013] As a further improvement of this utility model, the two L-shaped card holes are centrally symmetrical.

[0014] Compared with the prior art, this utility model provides a stamping and forming structure for sheet metal processing, which has the following beneficial effects:

[0015] 1. This stamping and forming structure for sheet metal processing, by setting a spring between two extrusion plates, allows the two extrusion plates to automatically move away from each other and return to their initial positions when the stamping rod is reset upwards. This ensures accurate reset of the extrusion plates and also applies a certain amount of pre-pressure to the workpiece, promoting the clamping and fixing of the workpiece and improving the stability of the overall structure.

[0016] 2. This stamping and forming structure for sheet metal processing involves inserting a workpiece with a connecting seat into a stripper plate with a retaining ring during installation. The connecting seats located on both sides of the workpiece's circumference slide vertically into the vertical surface of the L-shaped retaining hole. At this time, rotating the workpiece causes the retaining blocks on both sides of the connecting seat's circumference to engage with the horizontal end of the L-shaped retaining hole, thereby promoting the retaining and fixing of the workpiece and facilitating the loading and unloading of the workpiece.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] A stamping and forming structure for sheet metal processing, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the mold body includes an upper clamping plate 1, a stop plate 2, a lower mold base 3, and a stripper plate 5 stacked and spliced. A stamping rod 9 is vertically slidably inserted into the upper clamping plate 1 and the stop plate 2, and a linkage plate 7 is fixedly connected inside the lower mold base 3. An extrusion plate 6 is slidably connected inside the linkage plate 7, and a workpiece 4 is inserted between the two extrusion plates 6. The bottom of the workpiece 4 is connected to the stripper plate 5 through a snap-fit ​​assembly.

[0027] During operation, the stamping rod 9 presses downwards and fits against the top of the extrusion plate 6, causing the extrusion plate 6 to move horizontally within the linkage plate 7. This causes the two extrusion plates 6 to extrude the workpiece 4 located in the middle, thereby completing the shaping of the workpiece 4. After shaping, the workpiece 4 is removed from the mold body by the stripper plate 5.

[0028] The bottom inclined surface of the stamping rod 9 is adapted to the outer inclined surface of the extrusion plate 6, and the bottom side of the stamping rod 9 is in close contact with the top vertical surface of the extrusion plate 6.

[0029] To facilitate the automatic reset of the two extrusion plates 6 and ensure that the correct gap and position are maintained before the next operation, such as... Figure 1 As shown, a spring 8 is fixedly connected between the two extrusion plates 6. By setting the spring 8 between the two extrusion plates 6, the two extrusion plates 6 can automatically move away from each other and return to their initial positions when the stamping rod 9 is reset upwards. This ensures the accurate reset of the extrusion plates 6 and also applies a certain amount of pre-pressure to the workpiece 4, promoting the clamping and fixing of the workpiece 4 and improving the stability of the overall structure.

[0030] To facilitate the loading and unloading of workpiece 4, such as Figure 3 As shown, the snap-fit ​​assembly includes a connecting seat 401, a snap block 402, a snap ring 501, and an L-shaped snap hole 502. The connecting seat 401 is fixedly connected to the bottom of the workpiece 4. The two snap blocks 402 are respectively welded to the outer circumference of the connecting seat 401. The snap ring 501 is fixedly connected to the bottom outer wall of the stripper plate 5. The L-shaped snap holes 502 are respectively opened on both sides of the circumference of the snap ring 501. The two L-shaped snap holes 502 and the two snap blocks 402 are mutually adapted to each other. The two L-shaped snap holes 502 are centrally symmetrical.

[0031] During installation, the workpiece 4 with the connecting seat 401 is inserted into the stripper plate 5 with the retaining ring 501. The retaining blocks 402 on both sides of the circumference of the connecting seat 401 slide vertically into the vertical surface of the L-shaped retaining hole 502. At this time, the workpiece 4 is rotated so that the retaining blocks 402 on both sides of the circumference of the connecting seat 401 and the horizontal end of the L-shaped retaining hole 502 engage with each other. This promotes the locking and fixing of the workpiece 4 and also facilitates the loading and unloading of the workpiece 4.

[0032] 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.
