An anvil is provided at the inner bottom of the frame.
[0009] Further, the radius of the driven gear is smaller than the radius of the driving gear.
[0010] Further, an adjusting gear is rotatably installed inside the horizontal swing rod. An adjusting screw rod is threadedly connected inside the adjusting gear.

Detailed Implementation Manner
[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0029] Embodiment 1, as Figures 1-7 shown, a high-speed hammer forging device includes a frame 1. A working cylinder 2 is provided at the top of the frame 1. A working piston 21 is slidably connected inside the working cylinder 2. A hammer head 3 is fixedly connected to the bottom of the working piston 21. The hammer head 3 is composed of a hammer rod and a hammer disc. A plurality of groups of vertical swing grooves 31 are annularly formed on the outer side of the hammer rod. A plurality of groups of horizontal swing grooves 32 are annularly formed on the top of the hammer disc.
[0030] A vertical swing rod 5 is hinged inside the vertical swing groove 31. A horizontal swing rod 6 is hinged inside the horizontal swing groove 32. A cooperative air pressure chamber 33 is formed inside the hammer rod. A cooperative piston rod 34 is slidably connected inside the cooperative air pressure chamber 33. The cooperative piston rod 34 runs synchronously with the working piston 21. A driving gear 51 is provided at the hinge of the vertical swing rod 5. A connecting slider 52 is slidably connected to the outer side of the vertical swing rod 5. The connecting slider 52 is hinged to the cooperative piston rod 34. A sliding shaft 61 is provided at the hinge of the horizontal swing rod 6. A driven gear 62 is slidably connected to the sliding shaft 61. A hammer ring 4 is sleeved on the outer side of the hammer rod. The inner diameter of the hammer ring 4 is smaller than the outer diameter of the hammer disc.
[0031] During hammer forging, the equipment is started. Compressed gas is introduced into the upper half space of the working cylinder 2, and the lower half part exhausts. The air pressure pushes the working piston 21, and the working piston 21 drives the hammer head 3 to descend. At the same time, compressed gas is introduced into the upper half space of the cooperative air pressure chamber 33, and the cooperative piston rod 34 slides downward. The cooperative piston rod 34 drives the vertical swing rod 5 to swing downward through the connecting slider 52. The vertical swing rod 5 drives the horizontal swing rod 6 to swing upward synchronously through the driving gear 51 and the driven gear 62. The vertical swing rod 5 and the horizontal swing rod 6 lift and clamp the hammer ring 4. When the hammer head 3 strikes the workpiece, the driven gear 62 slides along the sliding shaft 61, and the driven gear 62 moves away from the driving gear 51. At this time, the horizontal swing rod 6 generates a supporting force on the hammer ring 4. The hammer ring 4 descends under the action of gravity, and the hammer ring 4 lands on the hammer plate. The hammer ring 4 gives a downward impact force to the hammer head 3 through gravity, and the impact force is transmitted to the workpiece again. Therefore, one impact can produce two hammer forging operations, which can make the deformation more stable, avoid excessive deformation of the workpiece due to too large a single impact force. The double impact can control the impact force and make the deformation of the forging more uniform, avoiding unnecessary stress concentration.
[0032] Since the air pressure inside the cooperative air pressure chamber 33 is the same as that inside the working cylinder 2, when the hammer ring 4 descends under the action of gravity, the air pressure inside the cooperative air pressure chamber 33 is always larger. Therefore, when the hammer ring 4 descends, the vertical swing rod 5 is not restricted either. The cooperative piston rod 34 pushes the vertical swing rod 5 to swing downward, and multiple groups of vertical swing rods 5 expand outward to restrict the bouncing of the hammer ring 4. Therefore, the stability of the secondary hammer forging can be ensured and the accuracy of the secondary hammer forging can be improved.
[0033] After one impact is completed, compressed gas enters the lower half space of the working cylinder 2, and the upper half space exhausts. The working piston 21 drives the hammer head 3 to rise. At the same time, the cooperative piston rod 34 drives the vertical swing rod 5 to swing upward and reset, and the driven gear 62 slides to mesh with the driving gear 51. During the next hammer forging, the hammer ring 4 can be lifted and clamped again.
[0034] The secondary hammer forging and resetting of the present invention can be quickly realized, achieving high-speed and high-quality hammer forging. At the same time, the hammer ring 4 can be freely replaced according to processing requirements, and the vertical swing rod 5 and the horizontal swing rod 6 can lift and clamp hammer rings 4 of different specifications, with a wide range of applications.
[0035] Embodiment 2, on the basis of the above embodiment, further includes that an air compression assembly 11 and a driving assembly 12 are arranged on the back of the frame 1. The driving assembly 12 is composed of a motor and an output belt pulley. An input belt pulley is arranged at the driving end of the air compression assembly 11, and the input belt pulley and the output belt pulley are connected by a transmission belt. The air compression assembly 11 can inject compressed gas into the upper half space and the lower half space of the working cylinder 2. The upper half space of the cooperative air pressure chamber 33 is connected to the upper half space of the working cylinder 2 through an upper conduit 22, and the lower half space of the cooperative air pressure chamber 33 is connected to the lower half space of the working cylinder 2 through a lower conduit 23. An anvil 13 is arranged at the inner bottom of the frame 1.
[0036] The workpiece is placed on the anvil 13, and the driving assembly 12 drives the air compression assembly 11 to operate. During hammer forging, compressed gas enters the upper half space of the working cylinder 2 and enters the upper half space of the cooperative air pressure chamber 33 through the upper conduit 22. During reset, the compressed gas enters the lower half space of the working cylinder 2 and enters the lower half space of the cooperative air pressure chamber 33 through the lower conduit 23. On the basis of the original equipment, there is no need to add an additional air pressure control system, and the structure is simple.
[0037] Embodiment 3: On the basis of the above embodiment, it further includes that the radius of the driven gear 62 is smaller than the radius of the driving gear 51. Through this design, when the vertical swing rod 5 swings downward by a small angle, the horizontal swing rod 6 swings upward by a large angle. Therefore, the hammer ring 4 can be lifted to a relatively high height, and sufficient hammer forging force can be generated.
[0038] Embodiment 4: On the basis of the above embodiment, it further includes that an adjusting gear 64 is rotatably installed inside the horizontal swing rod 6. An adjusting screw rod 66 is threadedly connected inside the adjusting gear 64. Both ends of the adjusting screw rod 66 are fixedly installed with connecting plates 67. The connecting plates 67 are located outside the horizontal swing rod 6. A top column 68 is fixedly installed on one side of the connecting plate 67 close to the horizontal swing rod 6. The top column 68 penetrates through the horizontal swing rod 6 and presses against the outside of the driven gear 62.
[0039] By controlling the rotation of the adjusting gear 64, the adjusting gear 64 drives the movement of the adjusting screw rod 66. The adjusting screw rod 66 drives the top column 68 to move through the connecting plate 67. The top column 68 drives the driven gear 62 to slide along the sliding shaft 61. And under the action of screw self-locking, when the adjusting gear 64 does not rotate, the position of the driven gear 62 remains stable.
[0040] Embodiment 5: On the basis of the above embodiment, it further includes that a slot 63 is opened inside the horizontal swing rod 6. A clamping hole is opened on the inner wall of the slot 63. A clamping block 65 is slidably connected inside the clamping hole. The top of the clamping block 65 is inclined. A clamping spring is arranged between the clamping block 65 and the inner wall of the clamping hole. A toothed plate 69 is inserted into the slot 63. The toothed plate 69 meshes with the adjusting gear 64. A pressing plate 610 is arranged on the outside of the toothed plate 69. A sliding cavity is opened inside the hammer head 3. A transmission rod 35 is slidably connected inside the sliding cavity. A top spring 36 is arranged between the transmission rod 35 and the inner bottom of the sliding cavity. The transmission rod 35 is designed in a U shape. One end of the transmission rod 35 close to the vertical swing rod 5 is provided with a wedge-shaped block. One end of the transmission rod 35 close to the horizontal swing rod 6 can be inserted into the slot 63. A sliding hole is opened on the inner wall of the sliding cavity. The sliding hole communicates with the horizontal swing groove 32. A top rod 37 is slidably connected inside the sliding hole. When the top rod 37 slides into the sliding cavity, it can drive the transmission rod 35 to rise through the wedge-shaped block.
[0041] When the hammer head 3 strikes, under the action of gravity, the hammer ring 4 will generate a downward inertial force. At this time, the pressure exerted by the hammer ring 4 on the pressure plate 610 is greater than the restraining force exerted by the clamping block 65 on the toothed plate 69. The pressure plate 610 drives the toothed plate 69 to move into the slot 63. The toothed plate 69 drives the adjusting gear 64 to rotate. The adjusting gear 64 drives the adjusting screw 66 to move. The adjusting screw 66 drives the ejector pin 68 to move through the connecting plate 67. The ejector pin 68 drives the driven gear 62 to slide along the sliding shaft 61. The driven gear 62 moves away from the driving gear 51. At this time, the horizontal swing rod 6 generates a supporting force on the hammer ring 4. The hammer ring 4 descends under the action of gravity. The hammer ring 4 lands on the hammer plate. The hammer ring 4 gives the hammer head 3 a downward impact force through gravity. The impact force is transmitted to the workpiece again. Therefore, one impact can generate two hammer forging operations.
[0042] After one impact is completed, compressed gas enters the lower half space of the working cylinder 2, and the upper half space exhausts. The working piston 21 drives the hammer head 3 to rise. At the same time, it cooperates with the piston rod 34 to drive the vertical swing rod 5 to swing upward and reset. The vertical swing rod 5 swings into the vertical swing groove 31. The vertical swing rod 5 pushes the ejector rod 37 to slide into the sliding cavity. The ejector rod 37 drives the transmission rod 35 to rise through the wedge block. The end of the transmission rod 35 close to the horizontal swing rod 6 pushes the toothed plate 69 to reset. The toothed plate 69 drives the adjusting gear 64 to reverse. The adjusting gear 64 drives the adjusting screw 66 to move. The adjusting screw 66 drives the ejector pin 68 to move through the connecting plate 67. The ejector pin 68 drives the driven gear 62 to slide along the sliding shaft 61. The driven gear 62 meshes with the driving gear 51. During the next hammer forging operation, the hammer ring 4 can be lifted and clamped again.
[0043] Through the setting of the present invention, there is no need to give drive to the adjusting gear 64, and the drive is automatically completed by using the inertial force of hammer forging, and the structure is compact.
[0044] Further, the pitch of the adjusting screw 66 is the same as the thickness of the driving gear 51. Through this design, the adjusting gear 64 rotates a smaller number of turns, the driven gear 62 moves away from the driving gear 51, and there is no need to set a large distance between the pressure plate 610 and the horizontal swing rod 6.
[0045] Furthermore, the bottom of the slot 63 is provided with a flared opening. Through the setting of the flared opening, when the transmission rod 35 jacks up the toothed plate 69, the transmission rod 35 does not affect the upward swing of the horizontal swing rod 6.
[0046] Embodiment Six, on the basis of the above embodiment, further includes that a receiving groove is provided inside the vertical swing groove 31, and the connecting slider 52 can be received in the receiving groove. Through the setting of the receiving groove, it is ensured that the vertical swing rod 5 can be completely received in the vertical swing groove 31.
[0047] Further, the depth of the horizontal swing groove 32 is greater than the sum of the thicknesses of the horizontal swing rod 6 and the pressing plate 610. With this design, the horizontal swing rod 6 can be completely received in the horizontal swing groove 32 without affecting the secondary hammer forging of the hammer ring 4.
[0048] The foregoing description of the disclosed embodiments enables those skilled in the art to practice or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
