It features a rotatable lower mounting platform that allows for direct quenching of the forging in a quenching tank after forging, effectively improving quenching efficiency. A support platform and a push rod are included, with the push rod located below the upper mounting platform.

Description

Technical Field

[0001] This invention relates to the field of valve manufacturing equipment technology, specifically to a high-efficiency multi-directional die forging device for special steel valves. Background Technology

[0002] Special steel valves are widely used in high-pressure, high-temperature pipeline systems in petrochemical, nuclear power, and shipbuilding industries. Valve bodies are typically formed using a multi-directional die forging process, which involves applying pressure to the billet simultaneously or sequentially from multiple directions, causing the metal to flow and form within a closed die cavity, resulting in a forging with a dense structure and excellent mechanical properties.

[0003] In multi-directional forging processes, special steels (such as stainless steel and heat-resistant alloy steel) have a narrow forging temperature window. After forging, the workpiece needs to be quenched as soon as possible to obtain the desired microstructure and mechanical properties. Currently, the lower die of multi-directional forging equipment is usually a fixed structure. After forging, the workpiece needs to be removed from the die and transferred to the quenching equipment by a robotic arm or other transfer mechanism. This transfer process is time-consuming, and the forging temperature drops significantly, resulting in poor quenching effect and affecting product quality. Therefore, a high-efficiency multi-directional forging device for special steel valves is needed to improve these problems. Summary of the Invention

Rotating shafts are fixedly connected to both sides of the support platforms. The rotating shafts are located below the push rods. The lower end of the push rod is inclined and can be located on one side of the rotating shaft. A talking spring is provided between the support platform and the support frame.

[0006] Preferably, a horizontal plate is fixedly connected to one side of the upper part of the vertical mounting plate. The horizontal plate passes horizontally through the support frame and is located above the upper mounting platform. A toothed plate is fixedly connected to one side of the lower end of the vertical mounting plate. The toothed plate is located on one side of the gear and meshes with the gear. The toothed plates on both sides are located on the front and rear sides of the gear. A spring is connected between the other side of the lower end of the vertical mounting plate and the support base.

[0007] Preferably, the upper mounting platform has openings on both sides, located below the horizontal plate. Movable plates are slidably connected inside each opening, and movable contact rods are fixedly connected below each movable plate. Connecting frames are fixedly connected between the movable contact rods. The lower end of each movable contact rod facing the support frame is inclined. Reversing blocks are symmetrically slidably connected inside the support frame. The side of the reversing block away from the support frame is inclined, and the lower end of the movable contact rod can be located on the inclined surface of the reversing block. Fixed frames are fixedly connected to both sides of the support frame. Bolts are rotatably connected inside the fixed frames. One end of the bolt is screwed into the reversing block, and the other end of the bolt is fixedly connected to a gear. Gear plate two and gear plate three are fixedly connected above and below gear two on one side of the vertical mounting plate. Gear plate two and gear plate three mesh with gear two. Multiple fixed blocks one are fixedly connected to one side of gear plate two. A movable block one is rotatably connected below fixed block one and magnetically attached to fixed block one. Multiple fixed blocks two are fixedly connected to one side of gear plate three. A movable block two is rotatably connected above fixed block two. Fixed blocks one and movable blocks two drive gear two to rotate.

[0008] Preferably, the bolt is a reverse bolt, which screws into the reversing block when rotated counterclockwise, pulling the reversing block to move towards the support frame; the bolt on the other side is a forward bolt.

[0015] This invention features a support platform and a push rod. The push rod is located below the upper mounting platform. During the mold closing process, the upper mounting platform first pushes the support platform below the lower mounting platform via the push rod to provide stable support for the lower mounting platform.

[0016] This invention features a vertical mounting plate and a reversing block. After the upper mounting platform opens the mold, it continues to move upward, driving the lower mounting platform to rotate via the vertical mounting plate. This reduces the number of driving components required for operation. Simultaneously, the reversing block allows the lower mounting platform to rotate back and forth via the vertical mounting plates on both sides, enabling it to rotate forward and backward. This allows the forging to be placed back and forth into the front and back sides of the quenching tank, providing two stations for retrieving the forging and allowing sufficient quenching time for the forging.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Example: Please refer to Figure 1-8 The high-efficiency multi-directional forging device for special steel valves shown includes a support frame 1, which serves as the load-bearing frame of the entire device. Made of high-strength steel, the support frame 1 possesses sufficient rigidity and strength to withstand the forging force during the multi-directional forging process. A hydraulic telescopic rod 2 is fixedly installed at the top inside the support frame 1. This hydraulic telescopic rod 2 is the main forging cylinder, providing vertical forging pressure. An upper mounting platform 3 is connected below the hydraulic telescopic rod 2. This upper mounting platform 3 serves as the upper die mounting seat, used to fix the upper die. A lower mounting platform 4 is installed inside the support frame 1 below the upper mounting platform 3. This lower mounting platform 4 serves as the lower die mounting seat, used to fix the lower die. The lower mounting platform 4 is rotatably connected to the support frame 1 via a connecting shaft 41 and can rotate around the connecting shaft 41. Side mounting platforms 7 are installed on both sides inside the support frame 1 between the upper mounting platform 3 and the lower mounting platform 4. These side mounting platforms 7 are used to install side dies, enabling the application of forging pressure to the billet from a horizontal direction. Support seats 5 are fixedly installed on both sides of the support frame 1. A hydraulic telescopic rod 6 is installed on the support seat 5. One end of the hydraulic telescopic rod 6 passes through the support frame 1 and connects to the side mounting platform 7 to provide horizontal forging pressure for the side mold. A quenching pool 10 is provided inside the support frame 1 below the lower mounting platform 4 to hold quenching media (such as water, quenching oil, etc.).

[0020] A connecting shaft 41 is fixedly connected to the lower mounting platform 4. The connecting shaft 41 is horizontally oriented, with both ends passing through the support frame 1 and located on both sides of the support frame 1. Gears 42 are fixedly connected to both ends of the connecting shaft 41, and gears 42 are located on the outside of the support frame 1. Vertical mounting plates 8 for driving the rotation of gears 42 are installed on both sides of the support frame 1. The vertical mounting plates 8 are arranged in a front-to-back mirror configuration on both sides of the support frame 1, that is, the vertical mounting plates 8 on the front and back sides have the same structure but are oriented in opposite directions.

[0021] In this embodiment, specifically: Push rods 101 are slidably connected to both sides of the support frame 1, allowing them to slide vertically up and down within the support frame 1. Support platforms 102 are slidably connected to both sides of the support frame 1, located below the lower mounting platform 4, allowing them to slide horizontally within the support frame 1. Rotating shafts 103 are fixedly connected to both sides of the support platforms 102, located below the push rods 101. The lower end of the push rod 101 is inclined; when the push rod 101 moves downwards, its lower inclined surface contacts the rotating shaft 103, generating a horizontal force that pushes the support platform 102 horizontally towards the center of the support frame 1. A spring 104 is provided between the support platform 102 and the support frame 1, used to reset the support platform 102 to its initial position after forging.

[0022] In this embodiment, specifically: a horizontal plate 81 is fixedly connected to one side of the upper part of the vertical mounting plate 8. The horizontal plate 81 passes horizontally through the support frame 1 and is located above the upper mounting platform 3. A toothed plate 82 is fixedly connected to one side of the lower end of the vertical mounting plate 8. The toothed plate 82 is located on one side of the gear 42 and meshes with the gear 42. The toothed plates 82 on both sides are located on the front and rear sides of the gear 42. A spring 86 is connected between the other side of the lower end of the vertical mounting plate 8 and the support base 5. The horizontal plate 81 is fixedly connected to one side of the upper part of the vertical mounting plate 8. The horizontal plate 81 passes horizontally through the support frame 1 in the horizontal direction, and its free end is located above the upper mounting platform 3. A toothed plate 82 is fixedly connected to one side of the lower end of the vertical mounting plate 8. The toothed plate 82 is located on one side of the gear 42 and meshes with the gear 42. The toothed plates 82 on both sides are located on the front and rear sides of the gear 42, forming a symmetrical drive structure. A spring 86 is connected between the other side of the lower end of the vertical mounting plate 8 and the support base 5. The spring 86 is used to reset the vertical mounting plate 8 to its initial position after the flipping action is completed.

[0023] In this embodiment, specifically: the upper mounting platform 3 has openings on both sides, located below the horizontal plate 81. Movable plates 31 are slidably connected inside each opening, and these plates 31 can slide vertically within the openings and can be completely retracted into the upper mounting platform 3. When the movable plates 31 are fully retracted, they do not contact the horizontal plate 81, and the up-and-down movement of the upper mounting platform 3 will not affect the horizontal plate 81. Movable contact rods 32 are fixedly connected below each movable plate 31, and connecting frames 33 are fixedly connected between the movable contact rods 32. The connecting frames 33 connect the movable contact rods 32 on both sides into one unit, ensuring synchronous movement on both sides. The lower end of each movable contact rod 32 is inclined towards the support frame 1.

[0024] A reversing block 9 is symmetrically slidably connected inside the support frame 1. The reversing block 9 can slide left and right within the support frame 1 in a horizontal direction. The side of the reversing block 9 away from the support frame 1 is an inclined surface, and the inclined surface at the lower end of the moving contact rod 32 can engage with the inclined surface of the reversing block 9. When the moving contact rod 32 moves downward, its lower inclined surface slides along the inclined surface of the reversing block 9, thereby moving the moving contact rod 32 along with the movable plate 31.

[0025] The support frame 1 is fixedly connected to two sides by fixed frames 91. Bolts 92 are rotatably connected inside the fixed frames 91. One end of the bolts 92 is screwed into the reversing block 9, and the other end of the bolts 92 is fixedly connected to a gear 93. The bolts 92 and the reversing block 9 form a helical pair. The rotation of the gear 93 is converted into the horizontal movement of the reversing block 9 through the bolts 92.

[0026] On one side of the vertical mounting plate 8, gear plate 2 83 and gear plate 3 84 are fixedly connected above and below gear 2 93, respectively. Both gear plate 2 83 and gear plate 3 84 mesh with gear 2 93. Multiple fixing blocks 1 831 are fixedly connected to one side of gear plate 2 83. A movable block 1 832 is rotatably connected below fixing block 1 831. The movable block 1 832 is magnetic and adheres to fixing block 1 831. Multiple fixing blocks 2 841 are fixedly connected to one side of gear plate 3 84. A movable block 2 842 is rotatably connected above fixing block 2 841. Movable block 1 832 and movable block 2 842 serve as unidirectional drives: when the vertical mounting plate 8 moves downward, movable block 1 832 contacts the tooth surface of gear 2 93, driving gear 2 93 to rotate counterclockwise; when the vertical mounting plate 8 returns to its original position, movable block 1 832 disengages from the tooth surface of gear 2 93, and gear 2 93 does not rotate; when the vertical mounting plate 8 moves upward, movable block 2 842 contacts the tooth surface of gear 2 93, driving gear 2 93 to rotate clockwise; when the vertical mounting plate 8 returns to its original position, movable block 2 842 disengages from the tooth surface of gear 2 93, and gear 2 93 does not rotate.

[0027] In this embodiment, specifically: bolt 92 is a reverse bolt, which screws into the reversing block 9 when rotated counterclockwise, pulling the reversing block 9 to move towards the support frame 1; bolt 92 on the other side is a forward bolt.

[0028] In this embodiment, specifically: the movable plate 31 can be completely retracted into the upper mounting platform 3, and the movable plate 31 does not need to contact the horizontal plate 81. When the movable plate 31 is fully retracted, the movable plate 31 does not contact the horizontal plate 81, and the up-and-down movement of the upper mounting platform 3 will not drive the horizontal plate 81.

[0029] In this embodiment, specifically: the support frame 1 is fixedly connected to limit grooves 85 on both sides of the hydraulic telescopic rod 6, and the vertical mounting plate 8 passes vertically through the limit grooves 85. The limit grooves 85 guide and limit the movement of the vertical mounting plate 8, ensuring that the vertical mounting plate 8 moves smoothly in the vertical direction.

[0030] In this embodiment, specifically: a slot is provided in the lower middle of the support platform 102, the connecting shaft 41 is located in the lower middle of the support platform 102, and two legs are provided at the other end of the support platform 102. The legs are inserted into the support frame 1 and located on both sides of the connecting shaft 41. The slot in the lower middle of the support platform 102 is used to avoid the connecting shaft 41, so that the support platform 102 will not interfere with the connecting shaft 41 when it moves under the lower mounting platform 4. Two legs are provided at the other end of the support platform 102, and the legs are inserted into the support frame 1 and located on both sides of the connecting shaft 41 to ensure the stability of the support platform 102 when sliding.

[0031] In this embodiment, specifically: a lifting platform 51 is fixedly connected to one side of the inside of the support base 5. The lifting platform 51 is located outside the gear 42, and one end of the hydraulic telescopic rod 6 is installed above the lifting platform 51. The design of the lifting platform 51 appropriately raises the installation position of the hydraulic telescopic rod 6, ensuring that the axis of the hydraulic telescopic rod 6 is aligned with the center of the side mounting platform 7, thus ensuring the correct direction of transmission of the horizontal forging force.

[0032] In this embodiment, specifically: a buffer mesh is installed inside the quenching tank 10. The buffer mesh is made of a high-temperature resistant material. The buffer mesh (not shown in detail in the figure) is horizontally positioned above the interior of the quenching tank 10. When the forging falls from the tilting lower mounting platform 4 into the quenching tank 10, it first contacts the buffer mesh. The buffer mesh acts as a buffer and decelerator, preventing the forging from directly impacting the bottom of the quenching tank and causing damage to the forging or the quenching tank. It also reduces the splashing of the quenching medium.

[0033] Working principle: The hydraulic telescopic rod 2 drives the upper mounting platform 3 to move downwards, and the upper mounting platform 3 drives the upper mold to move downwards. When the upper mounting platform 3 moves to a certain position, the push rod 101 moves downwards under the action of the upper mounting platform 3. The inclined surface at the lower end of the push rod 101 contacts the rotating shaft 103, generating a horizontal component force, which pushes the support platform 102 to overcome the elastic force of the spring 104 and move towards the middle of the support frame 1 until the support platform 102 is located directly below the lower mounting platform 4, providing stable support for the lower mounting platform 4.

[0034] The hydraulic telescopic rod 2 continues to drive the upper mounting platform 3 downward, while the hydraulic telescopic rod 6 drives the side mounting platforms 7 on both sides to close towards the center. The upper die and the side dies on both sides simultaneously apply forging pressure to the billet to complete the multi-directional die forging.

[0035] After forging, the hydraulic telescopic rod 2 drives the side mounting platform 7 to retract to both sides, the hydraulic telescopic rod 1 drives the upper mounting platform 3 to return upward, the push rod 101 moves upward with the upper mounting platform 3, and the support platform 102 returns to its initial position under the action of the spring 104, disengaging from below the lower mounting platform 4.

[0036] When the hydraulic telescopic rod 2 drives the upper mounting platform 3 to continue moving upward to its upper limit position, the movable plate 31 contacts the left horizontal plate 81 and pushes the horizontal plate 81 upward. The horizontal plate 81 drives the vertical mounting plate 8 upward. When the left vertical mounting plate 8 moves upward, its toothed plate 82 pushes the gear 42 to rotate clockwise (viewed from the front). The gear 42 drives the lower mounting platform 4 to flip forward through the connecting shaft 41, and the forging on the lower mounting platform 4 falls into the rear of the quenching pool 10.

[0037] At the same time, the toothed plate 3 84 on the left vertical mounting plate 8 moves upward, driving the gear 2 93 to rotate clockwise. The gear 2 93 pulls the reversing block 9 away from the support frame 1 through the bolt 92. (When the mold is closed again, the movable plate 31 moves along the inclined surface of 9 through the moving contact rod 32 during the descent, thereby retracting into the upper mounting platform 3. The movable plate 31 on the other side extends out of the upper mounting platform 3 with the drive of 33. After the mold is opened again, the movable plate 31 on the other side pushes the right horizontal plate 81 to move upward, thereby causing the lower mounting platform 4 to flip backward.)

[0038] At the same time, the toothed plate 83 on the right vertical mounting plate 8 moves downward, driving the gear 93 to rotate. The gear 93 pulls the reversing block 9 towards the support frame 1 via the bolt 92 (to prevent the right reversing block 9 from hindering the movement of the right movable plate 31 after it is moved out).

[0039] After the flipping is completed, the upper mounting platform 3 moves down to start the next forging cycle, and the vertical mounting plate 8 is reset by the action of spring 86, so that the lower mounting platform 4 returns to the horizontal position through gear 42.

[0040] In this cycle, the lower mounting platform 4 alternately flips forward and backward, and the forgings alternately fall into the front and rear sides of the quenching pool 10, providing operators with two retrieval stations for continuous production.

[0041] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
