Description

Technical Field

[0001] This utility model relates to the field of forging hydraulic press technology, and in particular to a protective forging hydraulic press. Background Technology

[0002] A forging hydraulic press is a mechanical device that uses liquid pressure to transmit energy and perform forging processes on metal materials. It is one of the key pieces of equipment in the forging industry. The industry uses forging hydraulic presses primarily due to their advantages in processing capacity, product quality, production efficiency, and cost control. When forging large components such as ship shafts and large generator rotors, enormous pressure is required to induce sufficient plastic deformation in the metal blank. Forging hydraulic presses can provide pressures of thousands or even tens of thousands of tons, ensuring the smooth forging of these large workpieces.

[0003] Its working principle is as follows: a metal billet is placed on the worktable of a forging hydraulic press. As the slide descends, pressure is applied to the billet, causing it to undergo plastic deformation, thereby obtaining the desired shape and size. By controlling the opening and closing degree and timing of the valves in the hydraulic system, the movement speed and pressure of the slide can be precisely adjusted to meet the requirements of different forging processes.

[0004] In existing technologies, some forging hydraulic presses rely on operators using tools such as pry bars and clamps to manually remove the forgings from the mold after forging. This method is inefficient, especially for large and heavy forgings, where manual operation is difficult and labor-intensive. Furthermore, manual operation makes it difficult to ensure the consistency and stability of demolding, which can easily damage the forgings and molds, affecting product quality and mold life. Therefore, a protective forging hydraulic press is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a protective forging hydraulic press, which aims to improve the problem in the prior art where manual demolding after forging easily damages the forgings and molds, affecting product quality and mold life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective forging hydraulic press includes a support body, a plurality of support columns fixedly connected to the top of the support body, support blocks fixedly connected to the top of the plurality of support columns, a drive assembly for applying pressure fixedly connected to the top of the support blocks, a mold cavity opened at the outer top of the support body, a top plate slidably connected inside the mold cavity, an electric push rod fixedly connected to the inner bottom of the support body, a driven plate slidably connected to the inner bottom of the support body, a driven block slidably connected to the top of the driven plate, a diagonal rod fixedly connected to the inner top of the support body, a sleeve column fixedly connected to the inner top of the support body, a sliding rod slidably connected inside the sleeve column, a spring sleeved on the outside of the sliding rod, a baffle fixedly connected to the outside of the sliding rod, and a plurality of telescopic rods fixedly connected to the inner bottom of the mold cavity.

[0008] As a further description of the above technical solution:

[0009] The driving assembly includes a cylinder, the bottom end of which is fixedly connected to the top end of the support block, the cylinder is fixedly connected to a connecting block, and the bottom end of the connecting block is fixedly connected to a pressure plate.

[0010] As a further description of the above technical solution:

[0011] Each of the multiple support columns is slidably connected to a sliding block 1. A sealing ring is fixedly connected to the bottom of the sliding block 1. Multiple sleeve rods are fixedly connected to the inside of the support column. Each of the multiple sleeve rods is slidably connected to a sliding block 2. A baffle 2 is fixedly connected to the bottom of the sliding block 2. A connecting block is fixedly connected to the top of the sleeve rod. A limit plate is fixedly connected to the top of the sliding block 2. A spring 2 is fixedly connected to the top of the connecting block.

[0012] As a further description of the above technical solution:

[0013] The drive end of the electric push rod is fixedly connected to the bottom end of the driven plate, and the interior of the driven block is slidably connected to the exterior of the inclined rod.

[0014] As a further description of the above technical solution:

[0015] The top end of the movable block contacts the bottom end of the sliding rod, the outside of the baffle is slidably connected to the inside of the sleeve column, and the other end of the telescopic rod is fixedly connected to the bottom end of the top membrane plate.

[0016] As a further description of the above technical solution:

[0017] The outside of the connecting block contacts the top of the support body, and the outside of the pressing template is slidably connected to the inside of the mold cavity;

[0018] As a further description of the above technical solution:

[0019] The outer side of the second baffle is slidably connected to the inside of the sleeve rod, the top end of the second sliding block is slidably connected to the inside of the connecting block, and the other end of the second spring is fixedly connected to the top end of the limiting plate;

[0020] As a further description of the above technical solution:

[0021] The interior of the first sliding block is in contact with the bottom of the second sliding block. The top of the sleeve rod has two oiling holes, and the top of the support block has multiple oiling grooves.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the driven plate is driven by an electric push rod, causing the driven block to slide and push against the sliding rod to rise. This, in turn, causes the top mold plate to slide upward. Then, in conjunction with the telescopic rod, the forging is demolded. There is no need for manual demolding using pry bars or clamps. For large and heavy forgings, this greatly reduces the difficulty and labor intensity of manual operation, effectively improves demolding efficiency, and avoids damage to the forging and mold caused by differences in manual operation, thus strongly ensuring the stability and reliability of product quality.

[0024] 2. In this utility model, when the cylinder drives the sliding block one to retract after the forging of the forging, it will squeeze the sliding block two, causing the lubricating oil inside the sleeve rod to flow into the interior of the sliding block one, and then be sealed by the sealing ring. During the forging and return strokes of the equipment during normal operation, lubrication is automatically triggered, ensuring that the support column can be lubricated in time during frequent operation, reducing the wear of the support column caused by friction, significantly extending the service life of the support column, and reducing the maintenance frequency and cost of the equipment.

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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a protective forging hydraulic press, comprising a support body 1, which serves as the basic structure of the entire hydraulic press. Multiple support columns 2 are fixedly connected to the top of the support body 1. The support columns 2 connect support blocks 3 to the support body 1, providing vertical support for the upper components and ensuring the stability of the overall structure. Support blocks 3 are fixedly connected to the top of the multiple support columns 2. The support blocks 3 serve as mounting platforms for the drive components, with a flat surface and stable structure, effectively bearing the forces generated during the operation of the drive components.

[0033] A pressure-applying drive assembly is fixedly connected to the top of the support block 3. This drive assembly includes a cylinder 4, which, as a key component providing pressure, converts pneumatic energy into mechanical energy to drive the movement of subsequent components. The bottom of the cylinder 4 is fixedly connected to the top of the support block 3, ensuring stable installation and preventing displacement during operation. A connecting block 5 is fixedly connected to the drive end of the cylinder 4. The connecting block 5 connects the cylinder 4 to the pressure template 6. Its structural strength is sufficient to transmit the strong pressure generated by the cylinder 4, and its exterior contacts the top of the support body 1, ensuring stability and guidance during movement. The bottom of the connecting block 5 is fixedly connected to the pressure template 6. The pressure template 6, as a component that directly contacts and applies pressure to the mold and workpiece, has a smooth surface with a certain degree of hardness and wear resistance, enabling it to evenly transmit pressure downwards.

[0034] The support body 1 has a mold cavity 7 at its outer top. The mold cavity 7 provides space and a running track for the mold and workpiece, and can accommodate molds of different specifications. The inner wall is specially treated to reduce frictional resistance and wear. The external sliding connection of the pressure plate 6 is to the inside of the mold cavity 7 to ensure the accuracy and stability of the pressure plate 6 during its up and down movement, and to prevent deviation or shaking. The mold cavity 7 is internally slidably connected to a top plate 8, which is used to lift the mold and workpiece during demolding. Its surface is flat and has a certain load-bearing capacity, which can stably support the mold and workpiece.

[0035] An electric push rod 9 is fixedly connected to the bottom of the support body 1. The electric push rod 9 serves as the demolding power source, precisely controlling the thrust and stroke to achieve stable lifting of the top mold plate 8. A driven plate 10 is slidably connected to the bottom of the support body 1. Driven by the electric push rod 9, the driven plate 10 can slide smoothly inside the support body 1, providing a foundation for power transmission to the upper components. The drive end of the electric push rod 9 is fixedly connected to the bottom of the driven plate 10, ensuring efficient and stable power transmission. A driven block 11 is slidably connected to the top of the driven plate 10. The driven block 11 can slide flexibly on the driven plate 10 and works in conjunction with other components to achieve power conversion and transmission.

[0036] A diagonal rod 12 is fixedly connected to the top of the support body 1. The diagonal rod 12 provides guidance and support for the movement of the driven block 11, and can convert the horizontal movement of the driven block 11 into the vertical movement of the sliding rod 14. The driven block 11 is internally slidably connected to the outside of the diagonal rod 12 to ensure the smoothness and accuracy of the movement of the driven block 11. A sleeve 13 is fixedly connected to the top of the support body 1. The sleeve 13 provides installation space and movement track for the sliding rod 14. Its internal structure is smooth and has high dimensional accuracy, reducing the frictional resistance when the sliding rod 14 moves. The sliding rod 14 is slidably connected inside the sleeve 13. The sliding rod 14 is the direct driving component for the rise of the top membrane plate 8. Its strength and rigidity meet the working requirements and can stably push the top membrane plate 8 to rise. The top of the driven block 11 contacts the bottom of the sliding rod 14, ensuring timely and effective power transmission. A spring 15 is sleeved on the outside of the sliding rod 14. The spring 15 is compressed during the upward movement of the sliding rod 14, storing elastic potential energy. After demolding, it provides power for the return of the sliding rod 14, and its elastic coefficient matches the working requirements, ensuring smooth movement. A baffle 16 is fixedly connected to the outside of the sliding rod 14. The baffle 16 slides inside the sleeve 13, limiting the stroke of the sliding rod 14 and stabilizing its movement. Its size and shape are adapted to the inside of the sleeve 13. The external sliding connection of the baffle 16 to the inside of the sleeve 13 ensures the smoothness and stability of the baffle 16's movement.

[0037] Multiple telescopic rods 17 are fixedly connected to the bottom of the mold cavity 7. The telescopic rods 17 play an auxiliary support and guiding role during the rising and falling of the top mold plate 8. They are flexible and highly stable, and can adapt to different working conditions. The other end of the telescopic rod 17 is fixedly connected to the bottom of the top mold plate 8 to ensure the smoothness and accuracy of the movement of the top mold plate 8.

[0038] Reference Figure 1 , Figure 2 , Figure 4 Each of the multiple support columns 2 has a sliding block 18 slidably connected to its exterior. The sliding block 18 slides on the support column 2 and generates relative friction with the support column 2 during movement. Its surface is specially treated to reduce the coefficient of friction and has a certain degree of wear resistance. A sealing ring 19 is fixedly connected to the bottom of the sliding block 18. The sealing ring 19 is used to prevent lubricating oil leakage. Its sealing performance is good and can effectively ensure the normal operation of the lubrication system.

[0039] Multiple sleeve rods 20 are fixedly connected inside the support block 3. These sleeve rods 20 provide installation space and a movement track for the sliding block 21, facilitating the storage and flow of lubricating oil. Sliding blocks 21 are slidably connected inside each of the sleeve rods 20. The sliding blocks 21 slide within the sleeve rods 20, controlling the flow and sealing of the lubricating oil, and their fit with the sleeve rods 20 is highly precise. The interior of the sliding block 18 contacts the bottom end of the sliding block 21, ensuring that lubricating oil release and sealing switching can be achieved under pressure.

[0040] A baffle 22 is fixedly connected to the outer bottom end of sliding block 21. Baffle 22 slides inside sleeve rod 20, controlling the opening and closing of the lubricating oil outlet and effectively controlling the flow rate and velocity of the lubricating oil. The outer side of baffle 22 is slidably connected to the inside of sleeve rod 20, ensuring the smoothness and stability of the movement of baffle 22. A connecting block 23 is fixedly connected to the inner top end of sleeve rod 20. Connecting block 23 provides limiting and guiding for the movement of sliding block 21, and its structure is stable and tightly connected to sleeve rod 20.

[0041] The top end of sliding block 21 is slidably connected to the inside of connecting block 23, ensuring the accuracy and stability of sliding block 21's movement. A limiting plate 24 is fixedly connected to the top end of sliding block 21. Under the action of spring 25, the limiting plate 24 cooperates with connecting block 23 to achieve the reset and locking of sliding block 21. Its structural strength meets the working requirements. Spring 25 is fixedly connected to the top end of the inside of connecting block 23. Spring 25 provides power for the reset of sliding block 21, and its elastic coefficient matches the working requirements, ensuring the smoothness and reliability of the movement. The other end of spring 25 is fixedly connected to the top end of limiting plate 24, ensuring that spring 25 can effectively act on limiting plate 24 and sliding block 21. Two oil inlets 26 are provided at the top end of sleeve rod 20. The oil inlets 26 serve as inlets for lubricating oil, and their position and size are rationally designed to facilitate the addition and replenishment of lubricating oil. The top of the support block 3 is provided with multiple oil grooves 27. The oil grooves 27 are used to guide the lubricating oil to the contact part between the sliding block 18 and the support column 2, so as to achieve uniform distribution and effective utilization of the lubricating oil.

[0042] Working principle: First, start cylinder 4. The drive end of cylinder 4 pushes the connecting block 5. Then, the connecting block 5 drives the pressure plate 6 to move downward. The pressure plate 6 slides inside the mold cavity 7, applying pressure to the mold and workpiece placed on the top plate 8 for forging.

[0043] When demolding is required, the electric push rod 9 pushes the driven plate 10 to move upward. The driven block 11 on the driven plate 10 slides upward along the inclined rod 12. The driven block 11 pushes the sliding rod 14 to slide upward inside the sleeve 13. The spring 15 outside the sliding rod 14 is compressed. The baffle 16 slides inside the sleeve 13. The upward movement of the sliding rod 14 drives the top mold plate 8 to slide upward through the telescopic rod 17, thereby lifting the mold and workpiece for demolding.

[0044] When lubrication of sliding block 18 is required, after the cylinder 4 drives the pressure plate 6 to forge the mold and then slides upward, it will cause sliding block 18 to slide upward. This will cause the interior of sliding block 18 to squeeze sliding block 21, which in turn will cause sliding block 21 to slide upward, opening the baffle 22. The lubricating oil stored inside the sleeve rod 20 will then flow out from the gap created by the upward sliding opening of the baffle 22, and subsequently flow into the interior of sliding block 18. The sealing ring 19 provides a seal for the lubricating oil. To prevent leakage, when forging again, cylinder 4 will drive the sliding block 18 containing lubricating oil to slide outside the support column 2, so that the lubricating oil is evenly lubricated under the sliding contact between the sliding block 18 and the support column 2, preventing wear on the support column 2 from repeated forging. When cylinder 4 drives the sliding block 18 to slide downward, it will release the pressure on the sliding block 21, and then the spring 25 will return to its original position, which will then drive the baffle 22 to re-seal the inner bottom of the sleeve rod 20.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
