Description

Technical Field

[0001] This utility model relates to the field of metal forging technology, specifically to forging dies based on forging part processing. Background Technology

[0002] Forgings are parts made through a forging process. Forging is a metal processing technique that uses forging equipment to induce plastic deformation, thereby changing the shape, size, and properties of metal. It is widely used in fields such as automotive parts. Forging dies are required in metal forging. Forging dies are an indispensable key tool in the forging process. They are used to apply pressure and shape control to metal billets, causing the metal to undergo plastic deformation within the cavity of the die, thereby obtaining forgings of the required shape and size.

[0003] Existing forging dies are generally divided into an upper die and a lower die. The lower die is connected to the base. By placing the metal billet on the lower die, the upper die is moved downward by a pressure device, which applies extrusion pressure to the workpiece, causing the metal to deform into the same shape as the inner cavity of the die. However, when removing the workpiece, the outer wall of the pressed workpiece tends to stick tightly to the lower die, making it difficult to remove. Existing methods generally use tools to pry it out, which can easily damage the workpiece. To address these issues, we provide a forging die based on forging processing. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a forging mold based on forging part processing. By setting up components such as a movable plate and a protective plate, after the workpiece is formed, the power mechanism drives the extrusion plate and the protective plate to move upward. The movable plate separates under the action of the elastic mechanism to facilitate demolding. When the workpiece is stuck to the inner wall of the movable plate and the movable plate cannot be separated, the workpiece inside is shaken open by tapping the outside of the movable plate. No tools are needed to pry it open, thus avoiding damage to the workpiece. This solves the problem that the outer wall of the workpiece after pressing is easily stuck tightly to the lower mold, making it difficult to remove. Existing methods generally require tools to pry it out, which can easily damage the workpiece.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a forging die for forging parts, comprising a base, a lower die assembly disposed on the upper surface of the base, an upper die assembly disposed above the lower die assembly, a power mechanism disposed on the outside of the upper die assembly to drive the upper die assembly to move up and down, the lower die assembly comprising a fixed plate, a movable plate slidably connected to the upper surface of the fixed plate, a limit mechanism disposed between the fixed plate and the movable plate, a connecting plate fixedly connected to the outer surface of the movable plate, and an elastic mechanism disposed on one side of the connecting plate; the upper die assembly comprising a pressing plate, a protective plate fixedly connected to the lower surface of the pressing plate.

[0008] Furthermore, the limiting mechanism includes a limiting groove, which is formed inside the fixed plate. A sliding block is slidably connected to the inner wall of the limiting groove, and the upper surface of the sliding block is fixedly connected to the movable plate.

[0009] Furthermore, the elastic mechanism includes a spring, one end of which is fixedly connected to the connecting plate, and the other end of which is inserted into the interior of the fixed plate and fixedly connected to the fixed plate.

[0010] Furthermore, a limit rod is provided inside the spring, and one end of the limit rod is fixedly connected to the connecting plate.

[0011] Furthermore, the power mechanism includes a support rod, the lower end of which is fixedly connected to the base, and the upper end of which is fixedly connected to a top plate.

[0012] Furthermore, an installation plate is integrally connected to the middle of the top plate, and a hydraulic rod is fixedly installed on the inner wall of the installation plate. The telescopic end of the hydraulic rod is fixedly connected to the extrusion plate.

[0013] Furthermore, a movable block is slidably connected to the outer surface of the support rod, and the outer surface of the movable block is simultaneously fixedly connected to the extrusion plate and the protective plate.

[0014] (iii) Beneficial effects:

[0015] Compared with existing technologies, this forging die based on forging process has the following advantages:

[0016] I. This forging die based on forging processing, by setting up components such as a movable plate and a protective plate, after the workpiece is formed, the power mechanism drives the extrusion plate and the protective plate to move upward. The movable plate separates under the action of the elastic mechanism to facilitate demolding. When the workpiece is stuck to the inner wall of the movable plate and the movable plate cannot be separated, the workpiece inside is shaken open by tapping the outside of the movable plate. No tools are needed to pry it open, thus avoiding damage to the workpiece. This achieves the effect of preventing workpiece damage, thereby solving the problem that the outer wall of the workpiece after pressing is easily stuck tightly to the lower die, making it difficult to remove. Existing methods generally use tools to pry it out, which can easily damage the workpiece.

[0017] II. This forging die based on forging processing incorporates components such as a limiting mechanism and a power mechanism. The sliding block is T-shaped, and the limiting groove has a T-shaped cross-section. The limiting groove limits the sliding block, preventing it from moving upward and thus preventing the movable plate from separating from the fixed plate, allowing the movable plate to slide only horizontally. When the hydraulic rod extends or retracts, it can drive the extrusion plate to move downward or upward, thereby completing the extrusion action. When the extrusion plate and the protective plate move upward or downward, they can drive the movable blocks to move upward or downward. There are four movable blocks, which are limited by four support rods to prevent the extrusion plate from tilting or shifting, thus increasing stability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The hydraulic rod 904 in this utility model is a common power device in the prior art, and this application will not elaborate on its model or internal structure.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a forging mold based on forging part processing, including a base 1, a lower mold assembly is provided on the upper surface of the base 1, an upper mold assembly is provided above the lower mold assembly, and a power mechanism 9 is provided on the outside of the upper mold assembly to drive the upper mold assembly to move up and down. The lower mold assembly includes a fixed plate 2, a movable plate 3 is slidably connected to the upper surface of the fixed plate 2, a limit mechanism 4 is provided between the fixed plate 2 and the movable plate 3, a connecting plate 5 is fixedly connected to the outer surface of the movable plate 3, and a spring mechanism 6 is provided on one side of the connecting plate 5; the upper mold assembly includes a pressing plate 7, a protective plate 8 is fixedly connected to the lower surface of the pressing plate 7, and the power mechanism 9 can drive the upper mold assembly to move downward, so that the pressing plate 7 and the protective plate 8 move downward, thereby pressing the metal part on the fixed plate 2. There are two movable plates 3, two connecting plates 5 and two spring mechanisms 6. The upper surface of the movable plate 3 is an inclined surface. When the protective plate 8 moves downward, the inclined surface on the movable plate 3 can be pressed first, so that the two movable plates 3 are closed together to form a sealed cavity.

[0027] The limiting mechanism 4 includes a limiting groove 401, which is formed inside the fixed plate 2. A sliding block 402 is slidably connected to the inner wall of the limiting groove 401. The upper surface of the sliding block 402 is fixedly connected to the movable plate 3. The sliding block 402 is T-shaped, and the cross-sectional shape of the limiting groove 401 is T-shaped. The limiting groove 401 can limit the sliding block 402 to prevent it from moving upward, thereby preventing the movable plate 3 from separating from the fixed plate 2 and allowing the movable plate 3 to slide horizontally only.

[0028] The elastic mechanism 6 includes a spring 601. One end of the spring 601 is fixedly connected to the connecting plate 5, and the other end of the spring 601 is inserted into the interior of the fixed plate 2 and fixedly connected to the fixed plate 2. The spring 601 gives the connecting plate 5 an elastic force that slides outward, so that the two connecting plates 5 move away from each other when there is no external force, thereby causing the two movable plates 3 to move away from each other.

[0029] The spring 601 is provided with a limiting rod 602 inside. One end of the limiting rod 602 is fixedly connected to the connecting plate 5. The limiting rod 602 is used to limit the part of the spring 601 located outside the fixed plate 2 to prevent it from bending backward.

[0030] The power mechanism 9 includes a support rod 901. The lower end of the support rod 901 is fixedly connected to the base 1, and the upper end of the support rod 901 is fixedly connected to the top plate 902. There are four support rods 901. The stability of the top plate 902 can be increased by the four support rods 901.

[0031] A mounting plate 903 is integrally connected to the middle of the top plate 902. A hydraulic rod 904 is fixedly installed on the inner wall of the mounting plate 903. The telescopic end of the hydraulic rod 904 is fixedly connected to the extrusion plate 7. When the hydraulic rod 904 extends or retracts, it can drive the extrusion plate 7 to move downward or upward, thereby completing the extrusion action.

[0032] The outer surface of the support rod 901 is slidably connected to a movable block 905. The outer surface of the movable block 905 is simultaneously fixedly connected to the extrusion plate 7 and the protective plate 8. When the extrusion plate 7 and the protective plate 8 move upward or downward, the movable block 905 can be driven to move upward or downward. There are four movable blocks 905, which are limited by four support rods 901 to prevent the extrusion plate 7 from tilting or shifting, thereby increasing stability.

[0033] Working principle: In use, the metal block to be pressed is placed above the fixed plate 2, between the two movable plates 3. Then, the power mechanism 9 drives the extrusion plate 7 and the protective plate 8 to move downward, so that the lower end of the protective plate 8 contacts the movable plate 3 and extrudes downward to press the movable plate 3. The two movable plates 3 move towards the middle, thus closing together and entering the interior of the protective plate 8, which fixes the two movable plates 3. Then, the extrusion plate 7 continues to move downward, and the metal block is extruded and forged inside the extrusion plate 7. After the workpiece is formed, the power mechanism 9 drives the extrusion plate 7 and the protective plate 8 to move upward, away from the connecting plate 5 and the movable plate 3. The movable plate 3 separates under the action of the elastic mechanism 6 to facilitate demolding. When the workpiece is stuck to the inner wall of the movable plate 3 and the movable plate 3 cannot be separated, the workpiece inside is shaken open by tapping the outside of the movable plate 3. No tools are needed to pry it open, avoiding damage to the workpiece and achieving the effect of preventing workpiece damage.
