Description

Technical Field

[0001] This utility model relates to the field of forging technology, specifically to forging dies for precision valve forgings. Background Technology

[0002] As a key mechanical device for controlling fluid flow, valves play an indispensable role in various pipeline systems and are widely used in many fields such as petroleum, chemical, electric power, and metallurgy. Their main functions include opening and closing pipelines, regulating flow direction, and accurately controlling parameters such as temperature, pressure, and flow rate of the transported medium. They are of great significance for ensuring the safe and stable operation of industrial production and the orderly conduct of daily life.

[0003] In the valve manufacturing process, forging is a crucial step. It is usually done by stamping forging or hydraulic forging. Stamping forging involves heating a metal block at high temperature until it reaches the metal's crystallization temperature. The specific temperature varies depending on the material. High temperature increases the plasticity of the metal. Then, by continuously hammering and using a mold on the outside of the metal, a product with a corresponding structure can be manufactured. Hydraulic forging, on the other hand, is used for larger parts with greater metal strength, such as the manufacture of some ultra-large pipelines for the West-East Gas Pipeline. It also involves heating at high temperature and then applying continuous pressure through a hydraulic forging machine, rather than hammering.

[0004] When using stamping and forging, on the one hand, the workers need to manually pull the required mold to the stamping position of the forging. This operation method is prone to inaccurate mold positioning due to human factors, which affects the stamping accuracy of the forging. On the other hand, after the lower mold is placed, it also needs to be manually held. Therefore, when stamping the forging, it is not only labor-intensive, but the lower mold is also prone to displacement. Utility Model Content

[0005] To address the issues of needing workers to pull the required mold to the forging stamping position and manually hold the lower mold after placement, this utility model aims to provide a precision valve forging mold.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: It includes a forging die worktable and a base. A placement platform is fixedly installed on the top of the base, and a support plate is fixedly installed on the upper surface of the base. A rotating mechanism is provided at the top of the support plate. The rotating mechanism includes a first cylinder. A connecting plate is fixedly installed on the driving end of the first cylinder. A T-shaped block is fixedly installed on the side of the connecting plate away from the first cylinder. A rack is fixedly installed on one side of the T-shaped block. A gear is meshed on the side of the rack away from the T-shaped block. A rotating shaft is fixedly installed in the middle of the gear. A rotating plate is fixedly installed at the top of the rotating shaft. A clamping mechanism is provided at the top of the rotating plate.

[0007] Preferably, the clamping mechanism includes a second cylinder, a connecting block is fixedly installed on the driving end of the second cylinder, two symmetrically distributed moving blocks are provided on the side of the connecting block away from the second cylinder, a first inclined plate and a second inclined plate are rotatably installed on the upper and lower sides of the connecting block, the moving blocks are rotatably connected to the first inclined plate and the second inclined plate respectively, the first inclined plate and the second inclined plate are opposite to each other, a U-shaped block is provided on the upper surface of the rotating plate, the U-shaped block is slidably connected to the moving block, an mounting plate is fixedly installed on the side of the moving block away from the first inclined plate, and clamping blocks are fixedly installed on the inner edge of the mounting plate.

Detailed Implementation

[0018] 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.

[0019] Example: Figure 1-5 As shown, this utility model provides a precision valve forging die, including a forging die worktable 1 and a base 11. A placement platform 12 is fixedly installed on the top of the base 11, and a support plate 13 is fixedly installed on the upper surface of the base 11. A rotating mechanism 2 is provided at the top of the support plate 13. The rotating mechanism 2 includes a first cylinder 22. A connecting plate 23 is fixedly installed on the driving end of the first cylinder 22. A T-shaped block 24 is fixedly installed on the side of the connecting plate 23 away from the first cylinder 22. A rack 25 is fixedly installed on one side of the T-shaped block 24. A gear 26 is meshed on the side of the rack 25 away from the T-shaped block 24. A rotating shaft 27 is fixedly installed in the middle. The rotating shaft 27 is rotatably clamped in the support plate 13. A rotating plate 28 is fixedly installed at the top of the rotating shaft 27. A clamping mechanism 3 is provided at the top of the rotating plate 28. It should be noted that the number of teeth on the rack 25 is such that the gear 26 only needs to be rotated 90 degrees. Then, the placement table 12 is used to place the unused lower mold. This application uses stamping and forging, which usually adopts equipment such as a crank press. The flywheel is driven by a motor, and the rotational motion is converted into the linear reciprocating motion of the slider through the crank connecting rod mechanism. The impact force of the slider is used to cause the metal billet to undergo plastic deformation in the mold.

[0020] The clamping mechanism 3 includes a second cylinder 31. A connecting block 32 is fixedly installed on the driving end of the second cylinder 31. Two symmetrically distributed moving blocks 33 are provided on the side of the connecting block 32 away from the second cylinder 31. A first inclined plate 34 and a second inclined plate 35 are rotatably installed on the upper and lower sides of the connecting block 32. The moving blocks 33 are rotatably connected to the first inclined plate 34 and the second inclined plate 35 respectively. The first inclined plate 34 and the second inclined plate 35 are opposite to each other. A U-shaped block 36 is provided on the upper surface of the rotating plate 28. The U-shaped block 36 is slidably connected to the moving blocks 33. An mounting plate 37 is fixedly installed on the side of the moving blocks 33 away from the first inclined plate 34. Clamping blocks 38 are fixedly installed on the inner edge of the mounting plate 37.

[0021] The T-block 24 is fitted with a fixed seat 4 on its outer side. The fixed seat 4 is fixedly connected to the support plate 13. By setting the fixed seat 4, when the rack 25 moves, the T-block 24 slides in the fixed seat 4, thereby making the rack 25 and the T-block 24 more stable when moving.

[0022] A locking block 5 is fixedly installed at the bottom of the connecting block 32, and a slot 51 for cooperating with the locking block 5 is opened at the top of the rotating plate 28. By setting the locking block 5, when the connecting block 32 moves, it drives the locking block 5 to slide in the slot 51 opened on the rotating plate 28, thereby making the connecting block 32 more stable when moving.

[0023] A first fixing plate 21 is fixedly installed on the upper surface of the support plate 13. The first cylinder 22 is fixedly connected to the first fixing plate 21. The driving end of the first cylinder 22 passes through the first fixing plate 21. By setting the first fixing plate 21, the first cylinder 22 is supported, so that the first cylinder 22 can work normally.

[0024] A second fixing plate 30 is fixedly installed at the top edge of the rotating plate 28. The second fixing plate 30 is fixedly connected to the second cylinder 31. The second cylinder 31 passes through the second fixing plate 30. By setting the second fixing plate 30, the second cylinder 31 is supported, so that the second cylinder 31 can work normally.

[0025] The bottom of the rotating plate 28 is provided with a disc 6, and four evenly distributed ring-shaped support legs 61 are fixedly installed at the bottom of the disc 6. The support legs 61 are fixedly connected to the support plate 13. The rotating shaft 27 rotates through the disc 6. By setting the disc 6 and the support legs 61, the rotating plate 28 is supported, making the rotating plate 28 more stable when rotating. At the same time, it also further supports the clamping mechanism 3, making the clamping mechanism 3 more stable when in use.

[0026] Working principle: In actual use, when the required lower die needs to be placed on the forging die worktable 1, the clamping mechanism 3 clamps the lower die on the placement table 12. Then, the first cylinder 22 is started, which drives the connecting plate 23, T-block 24, and rack 25 to move in the opposite direction of the first cylinder 22. During the movement of the rack 25, the gear 26 and the rotating shaft 27 rotate 90 degrees. The rotation of the rotating shaft 27 drives the rotating plate 28, the clamping mechanism 3, and the clamped lower die to rotate from the placement table 12 to the forging die worktable 1. Then, the forging is forged. During the forging, the operator needs to manually move the forging. At the same time, the clamping mechanism 3 continues to clamp the lower die.

[0027] The principle of clamping mechanism 3: The second cylinder 31 is activated, which drives the connecting block 32 to move in the direction of the second cylinder 31. As the connecting block 32 moves, the first inclined plate 34 and the second inclined plate 35 rotate, which drives the moving block 33 to move towards the center on the U-shaped block 36. The movement of the moving block 33 drives the mounting plate 37 and the clamping block 38 to move towards the center, so that the clamping block 38 fits against the outer wall of the upper and lower molds of the placement table 12, thereby achieving the clamping of the lower mold.

[0028] It should be noted that when the connecting plate 23 is in contact with the fixed base 4, it means that the movement of the rack 25 causes the gear 26 and the rotating shaft 27 to rotate 90 degrees. When the connecting plate 23 is in contact with the first fixed plate 21, it means that the movement of the rack 25 causes the gear 26 and the rotating shaft 27 to reverse 90 degrees.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
