Description

Technical Field

[0001] This application relates to the field of stamping dies, and particularly to a stamping die with a floating plate inner slider stripping mechanism. Background Art

[0002] In the design and application of stamping dies, the life of the die and the stability of the product are key factors that need to be prioritized in the design. As an important tool for product stamping production, the design of the die directly affects the forming quality and production efficiency of the product. Therefore, it is of great significance to optimize the die design to extend its service life and improve production stability.

[0003] As Figure 1 shown, in the use of an existing stamping die with a floating plate inner slider demoulding mechanism, especially when processing a product as Figure 1 shown, with a 90-degree right-angle surface on one side and a barb structure on the other side, some limitations have emerged. Since the punching force direction of the punching press is up and down, when the side of the product is formed, the barb structure on the other side of the product limits the possibility of directly removing the product from above. To solve this problem, the existing design adopts a stripping mechanism driven by an insert knife, that is, the forming block is driven to move horizontally forward by the insert knife, and when the die is opened, the insert knife is loosened, and the forming block retreats under the action of nitrogen in the driving seat to achieve the stripping effect.

[0004] However, this insert knife stripping mechanism has exposed some deficiencies in actual application. First, the structure at A of the mechanism is relatively weak, and this part bears a large stress and is prone to fatigue damage during long-term use, affecting the overall life of the die. Second, since the contact area between the product surface at B and the lower die workpiece is small, the product is unstable during the forming process. This instability not only increases the defective rate of the product during the production process but also may cause damage to the die itself, further shortening the service life of the die.

[0005] The above problems mainly stem from the fact that the balance between the die strength and the product stability in the existing design is not ideal enough. Insufficient die strength will lead to damage during long-term use, and the unstable placement of the product increases the risks during the production process. These two interact with each other and ultimately affect the service life and production efficiency of the die.

[0006] Therefore, it is particularly necessary to develop a new stamping die with a floating plate inner slider stripping mechanism. Utility Model Content

[0036] As Figure 3 and Figure 4 shown, this embodiment provides a stamping die with a floating plate inner slider stripping mechanism. Through precise structural design and component cooperation, this die effectively solves the problems faced by traditional stamping dies, such as short die life, poor product stability, and difficult demolding, when dealing with complex product shapes.

[0037] In terms of the specific structure, this die is composed of an upper die assembly 1 and a lower die assembly 2.

[0038] Specifically, the upper die assembly 1 is located directly above the lower die assembly 2, and the two are in precise resetable guiding cooperation through a guiding mechanism to ensure stable alignment during each stamping process.

[0039] It should be understood that the guiding mechanism usually adopts a combination of high-precision guide rods and guide sleeves, which can maintain stable movement even under high loads, ensuring the smoothness of die operation.

[0040] In this embodiment, the lower die assembly 2 is the basic part of the whole die, including a lower die base 3, a lower template 4 and a forming assembly 5.

[0041] In the above structure, the lower die base 3 is located at the bottom of the lower die assembly 2 and is the basic support structure of the die. It is made of high-strength alloy steel material and has excellent compressive and wear-resistant properties, ensuring the structural stability of the die under high-pressure operation.

[0042] The lower template 4 is fixedly installed on the lower die base 3 and serves as the installation platform for the forming assembly 5, ensuring the stability of the forming assembly 5 during stamping operations.

[0043] In this embodiment, the forming assembly 5 is composed of multiple key components, namely a floating plate 6, a base block 8, a sliding forming mechanism 9 and an inclined forming block 10.

[0044] Specifically, the floating plate 6 is located above the forming assembly and cooperates with the lower template 4 through a vertical spring 7 and a vertical guide rod (not shown in the figure), and can move freely in the up and down directions.

[0045] The base block 8 is fixedly installed on the floating plate 6 and is the core support component of the forming assembly. It bears the forming pressure and provides fixed installation positions for the sliding forming mechanism 9, the inclined forming block 10, etc. The cooperation between the base block 8 and the floating plate 6 ensures that the product remains stable during stamping and effectively disperses the stress generated during the operation, reducing die wear.

[0046] In this embodiment, the sliding forming mechanism 9 is installed on the base block 8 and includes a movable block 16, a pressing block 19 and a forming punch 20.

[0047] Among them, the movable block 16 is connected to the lower template 4 through a horizontal guide rail and a first horizontal spring 17 and can move flexibly in the horizontal direction.

[0048] The movement of the movable block 16 is driven by the cooperation of the inclined surface of the inserting tool 23. When the inserting tool 23 moves downward, it pushes the movable block 16 to move in the horizontal direction, thus ensuring the precise positioning of the product during the forming process.

[0049] The pressing block 19 is installed on the movable block 16 through a second horizontal spring 18.

[0050] The forming punch 20 is fixedly installed on the movable block 16.

[0051] In the above structure, specifically, the pressing block 19 is installed on the movable block 16 of the sliding forming mechanism 9, on the side close to the base block 8. The pressing block 19 provides a lateral supporting force through the second horizontal spring 18, whose function is to press against the side of the product during the bending forming process to ensure that the product does not shift or tilt during forming. The lateral supporting force of the pressing block 19 provides a stable reference surface for the forming punch 20 and the inclined forming block 10, enabling the product to be accurately positioned during the forming process.

[0052] The forming punch 20 is installed on the same side as the pressing block 19 and is also fixed on the movable block 16. The forming punch 20 cooperates with the inclined forming block 10 relatively through the horizontal movement of the movable block 16. When the forming operation starts, under the support of the pressing block 19, the forming punch 20 applies a forming pressure to the product in the horizontal direction, while the inclined forming block 10 performs a bending action in the opposite direction.

[0053] As the main forming part, in this embodiment, the inclined forming block 10 penetrates through the floating plate 6 and the base block 8 through an inclined installation groove, and realizes precise bending forming through the sliding forming mechanism 9 during the forming process. The design of the inclined forming block 10 can flexibly adapt to the complex geometric shape of the product and quickly reset after forming to avoid product damage caused by difficult demolding.

[0054] In this embodiment, the upper die assembly 1 includes a pressure plate 14, a pressure spring 13, and a ejector rod 15. The pressure plate 14 is installed below the upper die assembly and is aligned and cooperated with the base block 8 through a guide rod to ensure uniform force on the product during the forming process.

[0055] Among them, the lower end of the pressure plate 14 is provided with an ejector rod 15, which is used to push the floating plate 6 and the base block 8 to move downward synchronously when the upper die assembly moves downward to achieve precise forming of the product.

[0056] Among them, the pressure spring 13 is connected between the pressure plate 14 and the upper die assembly. A nitrogen spring is adopted, which has excellent elastic recovery performance to ensure stability during repeated stamping operations.

[0057] Among them, the ejector rod 15, as an extension of the pressure plate 14, is aligned and cooperated with the floating plate 6. When the upper die assembly moves downward, the ejector rod 15 pushes the floating plate 6 and the base block 8 to move downward through the action of the pressure plate 14, thereby completing the forming operation.

[0058] In addition, in order to drive the inclined forming block 10, the mold is also provided with an inclined drive push block 12 and an inclined spring 11. The inclined drive push block 12 is installed on the lower template 4 and is aligned and cooperated with the bottom end of the inclined forming block 10. The push block cooperates with the inclined forming block 10 through an inclined surface to ensure that the inclined forming block 10 can extend out of the working groove along the inclined surface when the floating plate 6 moves downward to complete the forming process of the product.

[0059] The inclined spring 11 is installed between the inclined forming block 10 and the base block 8 to provide the necessary reset force. After the forming operation is completed, the inclined spring 11 pushes the inclined forming block 10 to quickly return to the initial position, providing sufficient space for product demolding.

[0060] During the die operation, first, the upper die assembly 1 descends, and the pressure plate 14 pushes the floating plate 6 and the base block 8 to descend synchronously through the ejector rod 15. At this time, the inclined forming block 10 is in the initial position. As the upper die assembly 1 continues to descend, the insert knife 23 in the sliding forming mechanism 9 also begins to descend. The insert knife 23 cooperates with the movable block 16 through its inclined surface, pushing the movable block 16 to move horizontally. At the same time, it drives the inclined forming block 10 to move forward along the inclined groove and gradually extend to the working groove to contact the product surface.

[0061] The inclined forming block 10 bends the specified part of the product along the set bending line through the pushing force of the inclined surface. The forming surface of the inclined forming block 10 is closely attached to the product surface to complete the bending forming operation. After the forming is completed, the upper die assembly 1 gradually rises, the pressure of the pressure plate 14 is gradually released, the ejector rod 15 pushes the floating plate 6 and the base block 8 to rise together. Under the action of the inclined spring 11, the inclined forming block 10 quickly returns to the initial position through the resilience of the inclined surface, providing sufficient demolding space.

[0062] Based on the above content, it should be understood that the linkage design of the inclined forming block 10 and the floating plate 6 ensures that the forming block can flexibly adapt to the geometric shape of the product during the forming process and quickly retreat after the forming is completed, reducing fatigue damage caused by stress concentration. The 45-degree inclined design of the inclined forming block 10 enables it to achieve precise forming in a limited space and extends its service life through a wear-resistant coating.

[0063] Compared with the design of traditional dies, this structure not only enhances the overall strength of the die but also improves the flexibility of the forming operation, enabling the die to better handle the stamping tasks of complex product shapes.

[0064] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims.
