Description

Technical Field

[0001] This utility model relates to the field of forging die installation technology, specifically to a die forging fixing device. Background Technology

[0002] In the field of forging die installation technology, existing dies come in a variety of shapes, Figure 3 The mold shape shown is a commonly used mold with a specific structural form. In the prior art, when installing a forging mold, it is usually necessary to open a threaded hole in the mold and fix the mold to the forging table through a threaded connection. This installation method relies on the mold's own threaded structure to connect and position with the forging table.

[0003] However, existing technologies have significant shortcomings. On the one hand, creating threaded holes in the mold can lead to stress concentration at the threaded holes during forging, making the mold prone to fatigue fracture and affecting its service life and forging quality. On the other hand, the mold is prone to displacement during the forging and casting process, which not only results in low forging efficiency but also requires manual assistance to fix the ingot when it is displaced. During this process, ingot splashing can easily cause safety hazards and threaten the personal safety of operators. Utility Model Content

[0004] The present invention aims to provide a die forging fixing device to solve the problems of low efficiency caused by easy displacement of the forging ingot during the forming process of the existing technology, and the need for manual assistance to fix the ingot when it is displaced, which may cause splashing of the ingot and pose a safety hazard.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mold forging fixing device, including a base and a fixing block, wherein the bottom of the base is hollowed out, the fixing block is through the top and bottom, the fixing block is connected to the top of the base, the fixing block is connected to the base, the base is connected to the forging table, and the shape of the fixing block is adapted to the mold.

[0006] The working principle of this utility model is as follows: A hollowed-out base is connected to a forging table, providing stable support for the entire device. A fixing block runs vertically through the base and is connected to the top of the base, forming an integrated support structure. Its shape is adapted to the mold. The mold is placed inside the fixing block, which precisely positions and tightly fits the mold according to its contour, thus stably fixing the mold on the forging table. During the forging process, the connection between the base and the fixing block can evenly transmit the forging force to the base and the forging table. The connection and fixation between the base and the forging table effectively restricts the displacement of the mold, thereby achieving reliable fixation of the mold and ensuring the stability and safety of the forging process.

[0007] The beneficial effects of this utility model are as follows: The mold forging fixing device, by setting a hollowed-out base, reduces the overall weight of the device, facilitating installation and disassembly. Simultaneously, the hollowed-out structure does not affect the connection stability between the base and the forging table. The design of the fixing block, which runs vertically through the base, forms a continuous support channel, enhancing the overall structural rigidity of the device and effectively distributing stress during forging, reducing vibration and displacement. The shape of the fixing block adapts to the mold, enabling precise positioning and tight fit, preventing mold displacement during forging. This improves forging efficiency and reduces the safety hazard of ingot splashing caused by manual assistance in fixing the mold due to displacement. Furthermore, this structure eliminates the need for threaded holes in the mold, avoiding the problem of stress concentration at threaded holes leading to mold fatigue fracture in existing technologies, extending the mold's service life. The combined structure of the base and fixing block allows for flexible replacement according to different mold shapes, improving the device's versatility.

[0008] Furthermore, the fixing block is rectangular in shape, with a semi-circular groove at the center of its top. The rectangular shape and semi-circular groove at the center of the top allow the fixing block to fit the bottom contour of a circular or arc-shaped mold, further improving the positioning accuracy and fixing stability of the mold.

[0009] Furthermore, the diameter of the semi-circular groove ranges from 60 to 250 mm. This range allows for the installation of molds of different sizes, expanding the applicability of the device.

[0010] Furthermore, the diameter of the semi-circular groove is 90mm.

[0011] Furthermore, the width of the fixing block is the same as the width of the base. This design, where the width of the fixing block matches the width of the base, ensures a symmetrical overall structure and uniform force distribution, further enhancing the stability of the fixing device during the forging process.

[0012] Furthermore, the fixing block is located at the center of the top of the base. This centering ensures the balance of the mold's center of gravity during installation, preventing uneven stress and vibration caused by eccentric installation, and improving the reliability of the forging process.

[0017] The following detailed description illustrates the specific implementation method:

[0018] Example 1 is basically as shown in the appendix. Figure 1-2 As shown: A die forging fixing device includes a base and a fixing block. The bottom of the base is hollowed out and is slidably connected to the forging table. The fixing block is rectangular and has a semi-circular groove at the center of its top. The diameter of the semi-circular groove ranges from 60 to 250 mm. The fixing block is vertically continuous and its shape is adapted to the die. The fixing block is welded to the center of the top of the base and is connected to the base. The width of the fixing block is the same as the width of the base.

[0019] Example 2: A die forging fixing device, wherein the diameter of the semi-circular groove is 90mm.

[0020] The specific implementation process is as follows: During installation, select the corresponding mold according to the workpiece to be forged, and choose the corresponding fixing device according to the selected mold. First, fix the base horizontally to the forging table with bolts to ensure a tight fit without shaking. Then, embed the mold into the fixing block, with the semi-circular groove corresponding to the mold. At this time, the positioning is achieved by the tight fit between the inner wall of the groove and the mold. During the forging process, the pressure on the mold is transmitted to the main body of the fixing block, and then to the forging table through the connecting channel and the hollow area of ​​the base. Since the fixing block is centrally located and has the same width as the base, the force transmission path is symmetrical and balanced, which can effectively suppress the lateral displacement of the mold. The hollow design of the base does not weaken the support strength, but rather reduces the weight of the device by optimizing the material distribution, making it easy to disassemble and maintain.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
