Description

Technical Field

[0001] This utility model relates to the field of stamping and bending dies, and specifically to a bidirectional bending stamping die. Background Technology

[0002] In the field of cold stamping, stamping and bending dies play a crucial role. They are specially designed process equipment used to process various metal or non-metal materials into parts or semi-finished products with specific shapes and dimensions. Through the interaction of this die and a press, pressure can be applied to the material, causing plastic deformation. This plastic deformation process allows the material to undergo various processing operations such as bending, stretching, and forming according to predetermined design requirements. These operations are essential for manufacturing parts that meet precise specifications. Therefore, stamping and bending dies play an irreplaceable role in improving production efficiency, ensuring product quality, and reducing production costs.

[0003] While existing stamping dies can achieve the stamping effect, they can only complete bending operations in one direction at a time. This results in multiple bending operations required to stamp a C-shaped sheet into a square tube, which is cumbersome and inefficient. Furthermore, when the closed dimension of the square tube is small, existing stamping dies are often unable to complete the process due to die structure limitations, thus failing to meet actual production needs. Therefore, this utility model proposes a bidirectional bending stamping die. Summary of the Invention

[0004] This utility model provides a bidirectional bending stamping die. By improving the die, bidirectional bending can be achieved in a single stamping operation, solving the problems of cumbersome processing, low efficiency and limited die structure of existing dies.

[0005] The objective of this utility model is achieved through the following means:

[0006] A bidirectional bending stamping die includes a moving die and a fixed die. The fixed die is provided with a slidable support block. One end of the support block is provided with a swingable die core. A reset component is provided between the support block and the fixed die. Both the moving die and the fixed die are provided with a bending block and a fixing block that cooperate with the die core.

[0007] Furthermore, the fixed mold is provided with a limiting groove that cooperates with the support block, and the two sides of the support block are provided with limiting stops that cooperate with the limiting groove.

[0008] Furthermore, the limiting groove is provided through both sides of the fixed mold, and each end of the limiting groove is provided with a limiting block that cooperates with the support block.

[0009] Furthermore, the limiting groove has a T-shaped structure.

[0010] Furthermore, the reset assembly includes a support column and a reset spring. The support column is fixedly installed inside the fixed mold, and the reset spring is located between the support column and the support block.

[0011] Furthermore, one end of the support block is provided with a positioning block, and the mold core is oscillatingly mounted on the positioning block via a rotating shaft.

[0012] Furthermore, the fixed mold and the moving mold are respectively provided with mutually cooperating guide sleeves and guide posts.

[0013] The beneficial effects of this invention are as follows: The oscillating shaft allows for more flexible loading and unloading angles, thus improving installation efficiency. Furthermore, the cooperation of the support block, mold core, bending block, and fixing block enables bidirectional bending to be completed in a single operation, thereby increasing processing efficiency and reducing operational steps. The reset component allows the support block and mold core to automatically reset after each stamping cycle, facilitating rapid and continuous mold operation and improving production efficiency. Simultaneously, the bending method of the mold allows for successful processing even with small closed-end dimensions of square tubes, thus meeting production requirements.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] In this embodiment, refer to Figures 1-7 The specific implementation of the bidirectional bending stamping die includes a moving die 1 and a fixed die 2. The fixed die 2 is provided with a sliding support block 3. One end of the support block 3 is provided with a swingable die core 4. A reset component 5 is provided between the support block 3 and the fixed die 2. Both the moving die 1 and the fixed die 2 are provided with a bending block 6 and a fixing block 7 that cooperate with the die core 4.

[0024] like Figure 2 As shown, in use, the workpiece 9 is first placed on the mold core 4, and the workpiece 9 is brought into contact with the fixed block 7 on the fixed mold 2 by swinging the mold core 1. Then, the moving mold 1 and the fixed mold 2 are driven to perform a mold closing operation. When the mold is closed, the workpiece 9 comes into contact with the fixed block 7 on the moving mold 1, thereby pushing the workpiece 9 downward, so that it comes into contact with the bending blocks 6 on the moving mold 1 and the fixed mold 2 respectively, causing the workpiece 9 to bend in both directions. During this process, the reset component 5 is compressed and deformed, thereby accumulating elastic potential energy. When the mold is opened, the reset component 5 releases the accumulated elastic potential energy, pushing the support block 3 and the mold core 4 to quickly reset, thereby ejecting the workpiece 9 from the mold, which facilitates the removal of the workpiece and the stamping of the next workpiece 9.

[0025] The fixed mold 2 is provided with a limiting groove 21 that cooperates with the support block 3, and the support block 3 has limiting flanges 31 on both sides that cooperate with the limiting groove 21. The limiting groove 21 extends through both sides of the fixed mold 2, and each end of the limiting groove 21 has a limiting block 22 that cooperates with the support block 3. The limiting blocks 22 are fixedly installed on the fixed mold 2 with bolts. In this embodiment, the limiting groove 21 is formed by a recess in the area between the bending block 6 and the fixing block 7. Through the cooperation of the limiting groove 21, the limiting flanges 31 and the limiting blocks 22, the support block 3 can remain stable during sliding, without shaking or shifting, thereby improving the stability and processing accuracy of the mold. Furthermore, the limiting groove 21 has a T-shaped structure. The T-shaped limiting groove 21 provides more constraint to the support block 3 during sliding, thereby enhancing the stability of the support block 3.

[0026] Furthermore, the reset assembly 5 includes a support column 51 and a reset spring 52. The support column 51 is fixedly installed inside the fixed mold 2, and the reset spring 52 is located between the support column 51 and the support block 3. The support column 51 ensures that the reset spring 52 remains stable when compressed, preventing skewing or deformation. In this embodiment, three sets of reset assemblies 5 are used to make the support block 3 more stable during reset. The reset spring 52 is a cylindrical helical spring, which has good elasticity and resilience, allowing for repeated use and maintaining stable performance. When the reset spring 52 is compressed by the support block 3, it deforms and accumulates elastic potential energy. When the mold opens, the reset spring 52 releases the accumulated elastic potential energy, pushing the support block 3 and the mold core 4 to reset quickly. This causes the workpiece 9 to pop out of the mold, making material removal more convenient and faster, and also improving production efficiency.

[0027] One end of the support block 3 is provided with a positioning block 32, and the mold core 4 is oscillatingly mounted on the positioning block 32 via the rotating shaft 8. When installing the workpiece 9, the positioning block 32 enables the workpiece 9 to quickly separate from the support, thereby ensuring that the workpiece 9 is within the processing range. The rotating shaft 8 oscillates the mold core 1, causing the workpiece 9 to fit against the fixing block 7 on the fixed mold 2, thereby completing the rapid installation of the workpiece 9 and ensuring that subsequent stamping operations can proceed smoothly.

[0028] Furthermore, the fixed mold 2 and the moving mold 1 are respectively provided with a guide sleeve 23 and a guide post 11 that cooperate with each other. Through the cooperation of the guide sleeve 23 and the guide post 11, the moving mold 1 and the fixed mold 2 can maintain precise alignment during mold closing, thereby avoiding misalignment or deviation between the molds and improving the processing accuracy and stability of the molds. The guide sleeve 23 is fixedly installed on the fixed mold 2, and the guide post 11 is fixedly installed on the moving mold 1. The outer wall of the guide post 11 slides in conjunction with the inner wall of the guide sleeve 23, and the end of the guide post 11 is chamfered to facilitate the quick sliding of the guide post 11 into the guide sleeve 23. In this embodiment, the guide sleeve 23 has a cylindrical structure, and its inner diameter is slightly larger than the outer diameter of the guide post 11 to ensure that the guide post 11 can slide smoothly within the guide sleeve 23.

[0029] The beneficial effects of this utility model are as follows: The oscillating shaft allows for more flexible loading and unloading angles, thereby improving installation efficiency. Furthermore, the cooperation of the support block 3, mold core 4, bending block 6, and fixing block 7 enables bidirectional bending to be completed in a single operation, thus improving processing efficiency and reducing operational steps. The reset component 5 allows the support block 3 and mold core 4 to automatically reset after each stamping cycle, facilitating rapid and continuous mold operation and improving production efficiency. Simultaneously, the bending method of the mold allows for successful processing even with small closed-end dimensions of square tubes, thus meeting production requirements.
