Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of door hook processing technology, and more specifically, to a multi-directional forging die for a door hook. Background Technology

[0002] In modern industrial production and daily life, door hooks are widely used as a common connecting and hanging component in various doors, windows, cabinets and industrial equipment. With the continuous development of the manufacturing industry and people's increasing requirements for product quality and appearance, more stringent standards have been put forward for the performance and precision of door hooks.

[0003] Traditional door hook manufacturing processes mainly include casting and machining. Although casting can produce relatively complex shapes, the castings often have defects such as porosity and sand holes, resulting in insufficient strength and toughness of the door hooks. They are prone to breakage when subjected to large external forces, making it difficult to meet the requirements of some application scenarios with high safety performance. Moreover, the dimensional accuracy of the casting process is limited, and subsequent machining is usually required to achieve the required accuracy. This not only increases production costs but also reduces production efficiency.

[0004] When manufacturing door hooks using machining processes, the process typically involves gradually shaping the raw material through operations such as cutting and drilling. This method works well for door hooks with simple shapes, but it is extremely difficult to process door hooks with complex bends and multi-directional structures. It requires the use of multiple different processing equipment and complex tooling fixtures, and generates a large amount of waste during the process, resulting in low material utilization. Furthermore, machining makes it difficult to create ideal microstructures and mechanical properties in different parts of the door hook, thus failing to fully realize the potential of the material.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 1-4 As shown, it illustrates a multi-directional forging die for a door hook according to this disclosure, comprising:

[0036] Base frame 1, on which a molding box 2 is mounted;

[0037] Press molding component 3 is mounted on base frame 1;

[0038] Press-fit assembly 4, which is located at the upper end of molding box 2;

[0039] The pressing and molding component 3 includes a sliding strip 3-1, which is disposed on the upper end face of the base frame 1. A sliding block 3-2 is disposed on the sliding strip 3-1. A sliding groove 3-3 is disposed on the lower end face of the sliding block 3-2. The sliding strip 3-1 and the sliding groove 3-3 are fitted together. The upper end face of the sliding block 3-2 is fixedly connected to the molding box 2. A molding groove 3-4 is disposed on the upper end face of the molding box 2. A door hook groove 3-5 is disposed inside the molding groove 3-4.

[0040] The press-fit assembly 4 includes a mounting sleeve 4-1, the inner side wall of which is provided with an annular groove 4-2, a pressing rod 4-3 is inserted into the mounting sleeve 4-1, and the side wall of the pressing rod 4-3 is provided with an annular strip 4-4, which is embedded in the annular groove 4-2.

[0041] In some examples, the forming box 2 is mounted on the base frame 1. With the cooperation of the sliding bar 3-1 and the sliding block 3-2, the forming box 2 can slide smoothly along the sliding bar 3-1. This design helps to adjust the position of the forming box 2 during the forming process to meet different forging requirements. The preheated metal billet is placed in the hook groove 3-5 in the forming groove 3-4. At this time, the forming pressure block 3-7 will apply a certain pressure to the metal billet to initially shape the hook.

[0042] The lowering rod 4-3 is driven to descend by a hydraulic cylinder, and the annular bar 4-4 slides in the annular groove 4-2 to ensure that the lowering rod 4-3 descends smoothly. During the descent of the lowering rod 4-3, additional pressure is applied to the metal billet, causing it to deform in multiple directions, thereby realizing the multi-directional die forging of the door hook.

[0043] like Figures 1-4 As shown, in this embodiment, a molding cover 3-6 is provided on the upper end face of the molding box 2. The molding cover 3-6 is snapped onto the molding box 2. A molding block 3-7 is provided at the lower end of the molding cover 3-6. A corresponding groove 3-8 is opened on the molding block 3-7. The corresponding groove 3-8 matches the structure of the door hook groove 3-5.

[0044] In some examples, the molding cap 3-6 is snapped onto the molding box 2, so that the corresponding groove 3-8 on the molding block 3-7 is precisely aligned with the door hook groove 3-5.

[0045] For example, such as Figure 1 As shown, the inner sidewall of the molding box 2 is provided with a connecting hole 4-5, which is located on opposite sides of the molding box 2 and penetrates through the molding box 2.

[0046] In some examples, the through holes 4-5 on the inner sidewall of the molding box 2 can be used to clean the dust and impurities inside the molding groove 3-4.

[0047] For example, such as Figure 1 As shown, the outer side wall of the molding box 2 is provided with a flow guide plate 5, and the inner side wall of the flow guide plate 5 is provided with an insertion strip 6, which is inserted into the outer surface of the molding box 2.

[0048] In some examples, the metal billet may produce excess material, which is discharged from the mold through the guide plate 5. The insert strip 6 on the inner side wall of the guide plate 5 ensures that the guide plate 5 is tightly connected to the molding box 2.

[0049] For example, such as Figure 1 As shown, bolt holes 7 are provided on the base frame 1, and the bolt holes 7 are located at the four corners of the base frame 1.

[0050] In some examples, the base frame 1 is securely mounted on the worktable of the forging equipment using bolts through the bolt holes 7 at the four corners of the base frame 1, ensuring that the mold does not shift during operation.

[0051] For example, such as Figure 3 As shown, a pressing shaft 8 is provided at the bottom of the pressing rod 4-3, and an annular strip 4-4 is provided on the pressing shaft 8. The pressing shaft 8 is embedded inside the mounting sleeve 4-1.

[0052] In some examples, the pressure shaft 8 at the bottom of the pressure rod 4-3 is embedded inside the mounting sleeve 4-1.

[0053] For example, such as Figure 1 As shown, the molding box 2 has a molding cavity 9 inside, the molding groove 3-4 is opened inside the molding cavity 9, and the molding block 3-7 at the lower end of the molding cover 3-6 matches the structure of the molding cavity 9.

[0054] In some examples, the molding cavity 9 fits seamlessly with the molding caps 3-6.

[0055] For example, such as Figure 1 As shown, the lowering rod 4-3 is driven to rise and fall by a hydraulic cylinder.

[0056] In use, carefully place the preheated metal billet into the hook groove 3-5 within the forming groove 3-4 using pliers or other tools, ensuring the billet is placed stably and centered. Accurately fasten the forming cap 3-6 onto the forming box 2, ensuring the corresponding groove 3-8 on the forming block 3-7 is fully aligned with the hook groove 3-5. At this point, the forming block 3-7 will apply initial pressure to the metal billet, initially shaping the hook. Correctly connect the lower pressure rod 4-3 to the hydraulic cylinder, ensuring the hydraulic system can normally drive the lower pressure rod 4-3 to rise and fall. Turn on the hydraulic system and slowly adjust the pressure and stroke of the hydraulic cylinder to allow the lower pressure rod 4-3 to descend smoothly. The lower pressure shaft 8 at the bottom of the lower pressure rod 4-3 will embed into the mounting sleeve 4-1. The annular strip 4- 4. Slide within the annular groove 4-2 to ensure the stability of the lowering rod 4-3 during its descent. When the lowering rod 4-3 descends to a certain position, it applies additional pressure to the metal billet, causing it to deform in multiple directions, thereby achieving multi-directional die forging of the door hook. The lateral extrusion tool is driven by hydraulic equipment or other power devices to laterally extrude the metal billet. During the die forging process, the metal billet may produce excess material, which will be discharged from the mold through the guide plate 5. After the die forging is completed, the lowering rod 4-3 is first raised by the hydraulic system to return to its initial position. The formed door hook is then removed from the forming groove 3-4 using a demolding tool. Residual metal shavings, lubricant, and other impurities in the mold are removed using tools such as a brush and an air gun.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
