Technical Field

[0001] The utility model relates to the technical field of secondary die forging equipment, in particular to secondary die forging equipment for reshaping aircraft V-shaped die forgings. Background Art

[0002] Aircraft V-die forgings are metal forgings with a V-shaped cross-section, produced through a die forging process. These forgings are widely used in aircraft manufacturing, such as the wing frame beams of transport aircraft, and are a vital component of aircraft structures. Their primary function is to bear and transmit loads, ensuring the structural integrity and safety of the aircraft.

[0003] After the aircraft V-shaped die forgings are completed, some workpieces need to undergo secondary die forging. In the existing technology, the secondary die forging equipment is usually heated, placed in the die, and extruded by a punching machine to complete the secondary die forging process. The processed workpiece is then ejected by the ejection equipment. However, when the workpiece is die forging, the body is heated at a high temperature, and when the ejection mechanism is working, the workpiece inside the die will be ejected, causing the workpiece to fall into the processing environment or cause harm to the surrounding workers.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A secondary die forging equipment for repairing aircraft V-shaped die forgings includes: a workbench 1, a frame 2, a hydraulic rod 3 and an upper die 4, and the frame 2 is assembled on the top of the workbench 1, the hydraulic rod 3 is embedded in the inside of the frame 2, the upper die 4 is assembled on the outside of the output end of the hydraulic rod 3, the bottom of the upper die 4 is equipped with a rack 5, the top of the workbench 1 is equipped with a die group 6, and the outside of the die group 6 is equipped with a turning mechanism 7. The workbench 1, the frame 2, the hydraulic rod 3 and the upper die 4 are common die forging equipment in the prior art. The workbench 1 can support the die group 6, the frame 2 can support the hydraulic rod 3, and the hydraulic rod 3 can drive the upper die 4 to cooperate with the die group 6 to perform die forging.

[0024] See also Figure 3 and Figure 4 The turning mechanism 7 includes a worm gear 71 and a hollow gear 73. The worm gear 71 is connected to the mold group 6, and the outer part of the worm gear 71 is meshed with a worm 72. The outer part of the worm 72 is sleeved with a ratchet 74. The inner top of the hollow gear 73 is connected to a pawl 75 through a spring hinge. The worm gear 71 can be driven by the worm 72, and the hollow gear 73 can be driven by the rack 5. The cooperation of the ratchet 74 and the hollow gear 73 can make the rack 5 drive the pinching hollow gear 73 only after it returns to one-half, and drive the ratchet 74 and the worm 72 to rotate through the pawl 75. When the rack 5 drives the hollow gear 73 to rotate when it descends, it cannot drive the worm 72 to rotate. The spring hinge is a hinge commonly used in the prior art, which is internally equipped with a spring and can return to its original position after movement. The hollow gear 73, ratchet 74 and pawl 75 cooperate to form a ratchet gear device commonly used in the prior art.

[0025] A collection box 11 is inserted on the front of the workbench 1, and track blocks 12 are connected on both sides of the collection box 11. Cooling water can be stored inside the collection box 11 to cool the workpiece. The track blocks 12 improve the stability of the collection box 11 during movement, and track grooves that are compatible with the track blocks 12 are provided on both sides of the interior of the workbench 1. The workbench 1 is a block with an annular groove inside, and the bottom of the annular groove is connected to the top of the collection box 11. The collection box 11 can support the mold group 6 to rotate 180 degrees. The top and bottom of the mold group 6 are provided with a lower mold 61. The interior of the tool group 6 can be equipped with an ejection device commonly used in stamping dies to assist in discharging the workpiece. The lower die 61 can cooperate with the upper die 4 to perform secondary die forging on the workpiece. The outside of the worm gear 71 is equipped with a seat bearing 62, which is connected to the workbench 1. The seat bearing 62 can support the die group 6. The back of the worm 72 and the front of the hollow gear 73 are connected to the workbench 1 through a seat spherical bearing, and the ratchet 74 and the hollow gear 73 are connected through a seat spherical bearing. The seat spherical bearing can support and assemble the flip mechanism 7.

[0026] In this solution, the workpiece that needs secondary die forging is placed inside the lower die 61, and the hydraulic rod 3 is started to drive the upper die 4 to descend, and the workpiece is subjected to secondary die forging in cooperation with the die set 6. After the workpiece processing is completed, the hydraulic rod 3 drives the upper die 4 to return to its position. At this time, the rack 5 drives the meshing hollow gear 73 to rotate, and the hollow gear 73 drives the ratchet 74 to rotate through the internal pawl 75. The ratchet 74 drives the worm 72 to rotate, and the worm 72 drives the worm gear 71 to rotate 180 degrees, so that the top of the die set 6 rotates to the bottom. At the same time, the die set 6 rubs against the inner wall of the workbench 1 during rotation, thereby generating vibration that forces the internal workpiece to separate from the lower die 61. At this time, the workpiece falls into the collection box 11 for cooling and collection.

[0027] After the secondary die forging of the workpiece is completed, the added flipping mechanism 7 automatically drives the die group 6 to flip, and then the workpiece inside is dropped and collected, avoiding the traditional ejection mechanism from ejecting the high-temperature workpiece into the processing environment and making it impossible to collect it quickly, and at the same time causing harm to the workers through the high-temperature workpiece through the ejection mechanism. At the same time, when the flipping mechanism 7 is working, it uses the characteristics of the worm gear 71 and the worm 72 to automatically lock the die group 6, thereby improving the stability of the die group 6 during operation. When the die group 6 moves, it vibrates by rubbing against the inner wall of the workbench 1, avoiding the workpiece from being stuck in the interior of the lower die 61 and unable to be discharged normally.
