Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, specifically to a high-quality magnesium alloy forging die forging equipment. Background Technology

[0002] Forging equipment for magnesium alloys is an important process equipment in the metal processing field. It is mainly used to apply pressure to magnesium alloy billets through a die, causing plastic deformation to obtain forgings with the desired shape and properties. This type of equipment is widely used in fields with high lightweight requirements, such as aerospace, automotive, and electronics. The forming quality directly affects the mechanical properties and reliability of the final product. Currently, most common forging equipment focuses on the forging function, while often lacking systematic design in terms of the enclosure of the processing environment, dust control, and real-time cleaning.

[0003] For example, application number "CN202010525857.0" discloses a hot forging press. The clutch mechanism uses pneumatic action to drive the crankshaft via a flywheel, transferring flywheel energy to the crankshaft, enhancing the clutch effect and improving the press's stability and safety. The die height adjustment mechanism uses a motor to adjust the die height to accommodate different workpieces. Simultaneously, a dual-protection decoder in the signal transmission mechanism facilitates maintenance. However, existing magnesium alloy forging equipment still has several significant problems in actual operation. On the one hand, fine metal powder generated during forging easily escapes from the die gaps, polluting the working environment, increasing cleaning burden, and potentially causing dust explosions and other safety accidents. On the other hand, most equipment lacks an effective online cleaning mechanism. Powder accumulates on the die and worktable surfaces, easily causing indentations or pits on the billet surface during subsequent stamping processes, directly affecting the appearance and dimensional accuracy of the forgings and reducing product yield. Furthermore, even when some equipment is equipped with dust removal structures, incomplete cleaning often occurs due to insufficient airflow intensity and difficulty in covering dead corners, which can still affect the equipment's precision and service life over long-term operation. Therefore, there is an urgent need for a die forging forming equipment that can automatically achieve sealed dust suppression and efficiently collect and clean metal powder during the forging process, in order to improve forging quality, ensure operational safety, and facilitate maintenance. Summary of the Invention

[0004] This invention provides a high-quality magnesium alloy forging die forging equipment, which solves the problems mentioned in the background art.

[0007] According to one embodiment of the present invention, the cleaning mechanism includes a collection cavity, which is formed on the upper surface of the base. A pressure plate is formed on the upper surface of the base. The upper surface of the pressure plate and the upper surface of the base are set to the same horizontal plane. An annular groove is reserved between the edge of the pressure plate and the base. The annular groove is set on the outside of the mating ring. The bottom of the annular groove communicates with the collection cavity.

[0008] According to one embodiment of the present invention, a gap is reserved between the bottom of the mating ring and the pressure plate, a support column is fixedly connected to the bottom of the mating ring, the support column is evenly distributed around the bottom surface of the mating ring, the bottom of the support column is fixedly connected to the upper edge surface of the pressure plate, and the support column is arranged inside the ring groove, a sealing cover is fixedly connected to the bottom outer surface of the mating ring, the cross section of the sealing cover is set as L-shaped, and the bottom of the sealing cover is fixedly connected to the upper surface of the base.

[0009] According to one embodiment of the present invention, a vent hole is provided through the bottom outer surface of the base, and a cloth bag is attached to the vent hole, which is connected to the collection cavity.

[0010] According to one embodiment of the present invention, a mounting plate is fixedly connected to the bottom surface of the pressure plate, the bottom surface of the mounting plate is fixedly connected to the bottom surface of the gathering cavity, a mounting groove is formed on the upper edge surface of the mounting plate, a sliding groove is formed through the side surface of the mounting plate, and a first elastic telescopic ring is fixedly installed in the mounting groove.

[0011] According to one embodiment of the present invention, the output end of the first elastic telescopic ring is fixedly connected to an inner ring, the inner ring is slidably connected in the mounting groove, the outer surface of the inner ring is fixedly connected to a connecting rod, wherein the connecting rod is slidably disposed in the sliding groove, and the end of the connecting rod away from the inner ring is fixedly connected to an outer ring, the width of the outer ring is equal to the width of the ring groove, and the outer ring and the ring groove are directly opposite each other.

[0012] According to one embodiment of the present invention, elastic plates are fixedly connected to the upper and lower surfaces of the connecting rod, and air inlets are symmetrically opened through the upper edge of the pressure seat, with a one-way valve provided in the air inlet.

[0013] According to one embodiment of the present invention, a second elastic telescopic ring is fixedly connected to the lower outer surface of the mating ring. The second elastic telescopic ring communicates with the internal cavity of the first elastic telescopic ring. A driving ring is fixedly connected to the output end of the second elastic telescopic ring. The upper surface of the driving ring is positioned opposite the isolation ring.

[0014] When magnesium alloy needs to be forged into thin sheets, the magnesium alloy blank is placed on the upper surface of the pressure plate. Then, the external hydraulic equipment is driven to brake the pressure seat to move up and down along the slide bar. That is, the pressure seat enters the mating ring and begins to press the blank. The blank is processed and shaped by the cooperation between the pressure seat and the pressure plate.

[0015] This invention provides a high-quality magnesium alloy forging die forging equipment. It has the following beneficial effects: (I) In the process of processing, each stamping of the blank is carried out by the mating ring and the pressure seat, which makes the processing environment closed. This greatly reduces the safety hazards caused by the release of metal powder in the blank during the processing. At the same time, by setting the upper surface of the mating ring as an inclined surface, the docking accuracy of the pressure seat and the mating ring can be greatly improved, avoiding the problem of the pressure seat and the mating ring being unable to dock smoothly after long-term use due to slight displacement.

[0016] (II) In this high-quality magnesium alloy forging die forging equipment, when the pressure seat begins to dock with the mating ring, the internal cavity of the mating ring is initially closed. At this time, as the pressure seat continues to move downward, the internal cavity of the mating ring is under high pressure, that is, it begins to squeeze its internal air pressure into the ring groove through the cavity between its bottom support pillars, and finally into the collection cavity. It is then discharged to the outside through the vent holes reserved on the base. The movement of air will cause the metal powder on the upper surface of the bearing plate to move synchronously, that is, the metal powder enters the collection cavity for unified cleaning. The metal powder entering the vent holes is intercepted by the reserved cloth bag, thereby realizing the real-time collection of metal powder generated during operation, realizing the self-cleaning of the equipment during operation, greatly reducing the difficulty of subsequent cleaning, and avoiding the problem that a large amount of metal powder remains on the bearing plate, causing uneven pits on the outer surface of the blank during the stamping process, affecting the quality of the finished product, and greatly improving the yield of magnesium alloy sheets processed by this equipment.

[0017] (III) In this high-quality magnesium alloy forging die forging equipment, after the pressure seat completes the docking with the mating ring, the isolation ring gradually contacts the upper surface of the drive plate and begins to squeeze the drive ring as it continues to move downwards. This causes the drive ring to move downwards, driving the second elastic telescopic ring to expand. Its interior is under negative pressure, and it begins to draw air pressure from the interior of the first elastic telescopic ring, causing the first elastic telescopic ring to contract and drive the outer ring downwards, thereby releasing the seal on the ring groove. During this process, the pressure seat continues to move downwards, meaning that the internal cavity of the mating ring is already under high pressure. At the instant the ring groove is opened, the high-pressure gas instantly carries metal powder and is released from the ring groove. This automatically increases the air pressure inside the mating ring each time the metal powder is cleaned, thereby increasing the airflow intensity when the ring groove is opened. This allows for the flow of more metal powder, further improving the cleaning effect. When the pressure seat moves upward, the internal cavity of the mating ring is under negative pressure, meaning it begins to draw air pressure through the ring groove to replenish it. Simultaneously, as the pressure seat moves upward, the drive ring also continuously resets due to the upward movement of the isolation ring, meaning the outer ring also begins to reset. The outer ring's reset quickly restores the seal of the ring groove. At this time, the internal cavity of the mating ring, which is under negative pressure, can only be replenished by drawing air pressure through the air inlet. This allows for air pressure replenishment through the air inlet when the pressure seat moves upward, further blowing the metal powder inside the mating ring to flow. This avoids the problem of metal powder in dead corners not being cleaned in time for a long time. It also avoids the problem of reducing cleaning efficiency caused by directly drawing air pressure from the collection cavity through the ring groove and drawing metal powder along with it.

[0021] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a high-quality magnesium alloy forging die forging forming equipment, including a base 1, with slide rods 2 symmetrically fixedly connected to the upper surface of the edge of the base 1, and further including: Forging mechanism 3 is fixedly installed on base 1; Cleaning mechanism 4 is fixedly installed inside forging mechanism 3; The forging mechanism 3 includes an isolation ring 31.

The support column 44 is evenly distributed around the bottom surface of the mating ring 35. The bottom of the support column 44 is fixedly connected to the upper edge of the pressure plate 42. The support column 44 is located inside the ring groove 43. A sealing cover 45 is fixedly connected to the bottom outer surface of the mating ring 35. The cross-section of the sealing cover 45 is set as L-shaped. The bottom of the sealing cover 45 is fixedly connected to the upper surface of the base 1.

[0025] A ventilation hole 46 is provided through the bottom outer surface of the base 1. A cloth bag is attached to the ventilation hole 46, and the ventilation hole 46 is connected to the collection cavity 41.

[0026] A mounting plate 47 is fixedly connected to the bottom surface of the pressure plate 42. The bottom surface of the mounting plate 47 is fixedly connected to the bottom surface of the collection cavity 41. A mounting groove 48 is provided on the upper edge surface of the mounting plate 47. A sliding groove 49 is provided through the side surface of the mounting plate 47. A first elastic telescopic ring 410 is fixedly installed in the mounting groove 48.

[0027] An inner ring 411 is fixedly connected to the output end of the first elastic telescopic ring 410. The inner ring 411 is slidably connected in the mounting groove 48. A connecting rod 412 is fixedly connected to the outer surface of the inner ring 411. The connecting rod 412 is slidably arranged in the sliding groove 49. An outer ring 413 is fixedly connected to the end of the connecting rod 412 away from the inner ring 411. The width of the outer ring 413 is equal to the width of the ring groove 43, and the outer ring 413 and the ring groove 43 are directly opposite each other.

[0028] Elastic plates 414 are fixedly connected to the upper and lower surfaces of the connecting rod 412. An air inlet 415 is symmetrically opened through the upper edge of the pressure seat 34, and a one-way valve is installed inside the air inlet 415.

[0029] A second elastic telescopic ring 416 is fixedly connected to the lower outer surface of the mating ring 35. The second elastic telescopic ring 416 communicates with the internal cavity of the first elastic telescopic ring 410. A drive ring 417 is fixedly connected to the output end of the second elastic telescopic ring 416. The upper surface of the drive ring 417 is positioned opposite the isolation ring 31.

[0030] During operation, when magnesium alloy needs to be forged into thin sheets, the magnesium alloy blank is placed on the upper surface of the pressure plate 42. Then, the external hydraulic equipment is driven to brake the pressure seat 34 to move up and down along the slide rod 2. That is, the pressure seat 34 enters the mating ring 35 to begin stamping the blank. The blank is formed by the cooperation between the pressure seat 34 and the pressure plate 42. During the processing, each stamping of the blank is carried out by the cooperation between the mating ring 35 and the pressure seat 34, which keeps the processing environment in a closed state. This greatly reduces the safety hazards caused by the release of metal powder from the blank during processing. At the same time, by setting the upper surface of the mating ring 35 as an inclined surface, the connection between the pressure seat 34 and the mating ring 35 is greatly improved. To ensure precision and avoid the problem of slight displacement between the pressure seat 34 and the mating ring 35 after prolonged use, preventing successful docking, the internal cavity of the mating ring 35 is initially closed when the pressure seat 34 begins to dock with it. As the pressure seat 34 continues to descend, the internal cavity of the mating ring 35 becomes high-pressure, forcing its internal air pressure through the cavity between its bottom support pillars 44 into the ring groove 43, ultimately entering the collection chamber 41. This air pressure is then discharged outwards through the pre-reserved vent holes 46 on the base 1. The air movement also causes the metal powder on the upper surface of the pressure plate 42 to move synchronously, allowing the metal powder to enter the collection chamber 41 for easier cleaning. The metal powder entering the vent holes 46 is then blocked by the pre-reserved cloth bag. This process allows for real-time collection of metal powder generated during operation, enabling self-cleaning of the equipment and significantly reducing the difficulty of subsequent cleaning. It also prevents excessive metal powder buildup on the pressure plate 42, which could cause pitting on the blank surface during stamping and affect finished product quality. This greatly improves the yield rate of magnesium alloy sheets processed by this equipment. After the pressure seat 34 completes its docking with the mating ring 35, the isolation ring 31 gradually contacts the upper surface of the drive plate and, as it continues to move downwards, begins to compress the drive ring 417. This causes the drive ring 417 to move downwards, driving the second elastic telescopic ring 416 to expand. Its interior is under negative pressure, drawing air from the interior of the first elastic telescopic ring 410. The pressure causes the first elastic telescopic ring 410 to contract, moving the outer ring 413 downwards, thereby releasing the seal on the annular groove 43. During this process, the pressure seat 34 continuously moves downwards, meaning the internal cavity of the mating ring 35 is already under high pressure. The instant the annular groove 43 is opened, the high-pressure gas instantly carries metal powder and is released from the groove 43. This automatically increases the air pressure inside the mating ring 35 each time metal powder is cleaned, thus increasing the airflow intensity when the annular groove 43 is open, allowing more metal powder to flow and further improving the cleaning effect. When the pressure seat 34 moves upwards, the internal cavity of the mating ring 35 is under negative pressure, meaning it begins to draw pressure from the annular groove 43 to replenish it.Simultaneously, as the pressure seat 34 moves upward, the drive ring 417 also continuously resets due to the upward movement of the isolation ring 31, meaning the outer ring 413 also begins to reset. The reset of the outer ring 413 quickly restores the seal of the ring groove 43. At this time, the cavity inside the mating ring 35, which is under negative pressure, can only be replenished by drawing air pressure through the air inlet 415. This allows for air pressure replenishment through the air inlet 415 as the pressure seat 34 moves upward, further agitating the flow of metal powder inside the mating ring 35. This avoids the problem of metal powder remaining in dead zones for extended periods without being cleaned in time. It also prevents the reduction in cleaning efficiency caused by directly drawing air pressure from the collection cavity 41 through the ring groove 43, which would otherwise also draw out metal powder.
