Description

Technical Field

[0001] The present invention relates to the technical field of aviation seat processing, and particularly relates to a forging press for processing forgings of an aviation seat air spring cylinder body. Background Art

[0002] An aviation seat is a core device in an aircraft cabin that provides passengers with safe riding, comfortable experience, and function adjustment. An air spring cylinder body is used when the aviation seat is adjusted. The material of the air spring cylinder body is generally an aluminum forging for aerospace. The aviation seat air spring cylinder body is one of the core components of an aircraft seat adjustment system. Its function is to adjust the seat height, tilt angle, leg rest position, etc. through gas pressure. When producing the air spring cylinder body, a forging press is required for processing, and a forging press is used during forging;

[0003] For this reason, the patent with the publication number CN206425465U discloses a forging press. It mainly solves the problem that the forging plate of the existing forging press sometimes moves inaccurately during operation, resulting in poor practical effects. The utility model provides a forging press, the frame of which includes a base and a crossbeam. A forging plate driven by a hydraulic cylinder to reciprocate up and down is provided on the crossbeam. A workpiece placement platform corresponding to the forging plate is provided on the base. The hydraulic cylinder includes a push rod for driving the forging plate to move. A guide sleeve sleeved around the push rod is provided at the bottom of the crossbeam. A plurality of guide ribs extending in the vertical direction are provided on the outer wall of the circumference of the push rod. A guide groove slidably matched with the guide ribs is provided in the guide sleeve. When the forging plate moves, guiding can be achieved through the guide groove in the slidably matched guide sleeve and the guide ribs on the outer circumference of the push rod, with accurate positioning and convenient use;

[0004] The above-mentioned existing technical solutions have the following defects: The above-mentioned technology uses the guide groove in the slidably matched guide sleeve and the guide ribs on the outer wall of the push rod to achieve guiding during use, with accurate positioning and convenient use. However, when forging a workpiece, the impact force will be transmitted to the mold and the workpiece through the workbench, resulting in the deviation of the mold positioning and the increase of the workpiece size error, directly affecting the processing accuracy. And the unshock-absorbed workbench may cause resonance due to the coincidence of the vibration frequency and the natural frequency of the equipment, further amplifying the vibration amplitude, causing deformation of the workbench or fracture of key components, presenting potential safety hazards. Therefore, a forging press for processing forgings of an aviation seat air spring cylinder body is needed to solve the above problems. Summary of the Invention

[0009] Preferably, multiple groups of telescopic springs are provided, and a telescopic structure is formed between the multiple groups of telescopic springs and the movable seat.

[0010] Preferably, a through hole is formed at the middle position inside the movable seat, fixing seats are fixed on both sides of one end of the movable seat, a sealing cover is hinged at the middle position of the fixing seats, torsion springs are fixed on both sides at the middle position of the fixing seats, one end of the torsion spring is fixed to one side of the fixing seat, and the other end of the torsion spring is fixed to one side of one end of the sealing cover.

[0011] Preferably, two groups of shock absorption cylinders are provided, and the two groups of shock absorption cylinders are symmetrically distributed on one side of the fixing block.

[0012] Preferably, a noise reduction structure is arranged inside the fixing block, the noise reduction structure includes a cavity, the cavity is formed inside the fixing block, a barrier block is fixed at the bottom end inside the cavity, a pressing rubber block is installed at the top end inside the cavity, a moving groove is formed at the top end inside the fixing block, a connecting rod is inserted inside the moving groove, the bottom end of the connecting rod is fixed to the top end of the pressing rubber block, and a connecting frame is fixed at the top end of the connecting rod, and one side of the connecting frame is fixed to one side of the upper mold.

[0013] Preferably, the connecting rod is inserted into the interior of the movable groove, and a sealed connection is formed between the connecting rod and the movable groove.

[0014] Preferably, a noise reduction plate is installed on one side of the fixing block, a silencer hole is opened inside the noise reduction plate, a baffle plate is installed inside the silencer hole, and the baffle plate is distributed in a ring shape on one side inside the silencer hole.

[0015] Preferably, the sound-absorbing holes are provided in a plurality of groups, and the plurality of groups of sound-absorbing holes are arranged at equal intervals inside the noise reduction plate.

[0016] The forging machine for processing the cylinder forging of an air spring for an aviation seat provided by the present invention has the advantages that: when the vibration generated by forging of the upper die is transmitted to the base, a shock absorbing effect can be achieved on the vibration of the base, and a noise reduction effect can be achieved on the noise generated by forging by the noise reduction structure;

[0017] By providing a shock-absorbing structure, when the upper die is forging the cylinder, the upper die will drive the extrusion rubber block to squeeze the air inside the cavity into the airbag during the descending process, so that the airbag expands and moves the second magnet to one side, so that a non-contact suspension gap is formed between the second magnet and the first magnet, and the vibration energy is absorbed or dispersed through the continuous force of the magnetic field, thereby reducing the transmission of the vibration force and achieving a preliminary shock-absorbing effect;

[0018] Furthermore, when the second magnet moves to one side, it will drive the piston to move inside the shock absorber cylinder, and absorb the hydraulic oil on one side of the inner cavity of the shock absorber cylinder to the other side of the inner cavity. When vibrating, the piston will squeeze the hydraulic oil back to its original position through the through hole. Since the inner diameter of the through hole is relatively small, when the hydraulic oil passes through the small hole at high speed, a local pressure drop is generated due to the aperture limitation, and the oil and the hole wall rub violently, converting the mechanical vibration energy into heat energy and dissipating it into the environment, thereby reducing the energy transfer efficiency, achieving the goal of significantly weakening the energy of the vibration, reducing the impact force generated by the vibration, and transmitting it to the mold and the workpiece through the workbench, resulting in mold positioning deviation and workpiece size error increase, directly affecting the processing accuracy, thereby completing the multiple shock absorption work of the workbench;

[0019] By providing a noise reduction structure, when the upper mold moves downward, it squeezes the rubber block to move inside the cavity, and the air inside the cavity is greatly discharged. Reducing the air in the cavity can achieve the effect of reducing noise. The vibration of air molecules is an important factor in the generation and propagation of noise. Reducing the air in the cavity means reducing the number of air molecules involved in the vibration, thereby reducing the amplitude and intensity of the air vibration, and achieving the effect of noise reduction.

[0020] Furthermore, through the setting of the sound absorption holes inside the noise reduction plate, when sound waves enter the inside of the sound absorption holes, the vibration of the air inside the holes will be caused. Due to the friction between the air and the hole walls and the interaction between air molecules, the sound energy will gradually be converted into heat energy and dissipated, thus completing the work of noise reduction.

[0036] Refer to Figures 7-12As shown: When forging the air spring cylinder of an aviation seat, the raw material of the cylinder is placed in the forging groove inside the lower die 3. During forging, the hydraulic cylinder 4 is started to push the upper die 7 downward. The raw material of the cylinder is forged by the forging head at the bottom of the upper die 7, so as to forge the raw material of the cylinder into a cylinder, completing the forging work of the air spring cylinder of the aviation seat. When the upper die 7 moves downward, it will drive the connecting rod 506 downward through the connecting frame 502. When the connecting rod 506 moves downward, it will push the extrusion rubber block 503 to move downward inside the cavity 505. The connection between the connecting rod 506 and the moving groove 501 is sealed by a sealing ring. When the extrusion rubber block 503 moves inside the cavity 505, it will squeeze out the air inside the cavity 505, greatly reducing the air inside the cavity 505. Reducing the air in the cavity 505 can achieve the effect of reducing noise. Sound propagation requires a medium, and air is one of the common sound propagation media. When the forging machine is working, it will cause the vibration of the surrounding air. Reducing the air in the cavity 505 means reducing the number of air molecules participating in the vibration, thereby reducing the amplitude and intensity of the air vibration and reducing the propagation of noise. The less air there is, the more obvious the attenuation of sound when propagating in the cavity 505. During the propagation of sound, it needs to rely on the interaction of air molecules to transfer energy. When the air in the cavity 505 is thin, the distance between air molecules increases, and the obstacles encountered by sound during propagation increase, and the energy transfer efficiency decreases, so the propagation of sound will be weakened. When the noise generated by the forging machine propagates to the outside through the cavity 505, the intensity will be significantly reduced, thus achieving a sound insulation and noise reduction effect. And a noise reduction board 504 is also provided on one side of the fixed block 8. The setting of the sound absorption holes 507 inside the noise reduction board 504 can cause the vibration of the air inside the holes when the sound wave enters the inside of the sound absorption holes 507. Due to the friction between the air and the hole wall and the interaction between air molecules, the sound energy will gradually be converted into heat energy and dissipated, so as to achieve the purpose of sound absorption and noise reduction. And the setting of the baffle 508 inside the sound absorption hole 507 can change the propagation direction of the sound wave inside the sound absorption hole 507, making the sound wave experience more reflections inside the hole. Every time the sound wave contacts the surface of the baffle 508, a part of the sound energy will be absorbed or reflected. After multiple reflections, more sound energy will be consumed, thereby improving the sound absorption effect and achieving a multiple noise reduction effect, thus improving the working environment of the staff and reducing employee fatigue. Noise can cause employee fatigue, inattention and restlessness. Through the noise reduction setting, the working environment is made more comfortable, employees can better concentrate on completing work tasks, reduce operation errors caused by fatigue and distraction, enable employees to work continuously and stably, ensure the continuity of production, and thus improve the overall work efficiency;

[0037] The shock-absorbing structure 6 includes a barrier block 603 which is installed inside the fixed block 8. A gasbag 604 is fixed to the bottom end of the barrier block 603. A second magnet 605 is fixed to one side of the gasbag 604. A first magnet 602 is arranged on one side of the second magnet 605. One side of the first magnet 602 is fixed to the outer side of the workbench 2. A shock-absorbing cylinder 601 is fixed to the other side of the fixed block 8. A piston 606 is installed inside the shock-absorbing cylinder 601. One end of the piston 606 is fixed to one side of one end of the second magnet 605. A guide groove 607 is formed inside one side of the fixed block 8. One end of the piston 606 penetrates through the inside of the guide groove 607. A guiding structure is formed between the guide groove 607 and the piston 606. A fixed disk 608 is fixed to one side inside the shock-absorbing cylinder 601. A through groove 6016 is formed inside the fixed disk 608. A movable seat 6012 is installed on one side inside the through groove 6016. An installation groove 6014 is formed inside one side of the fixed disk 608. A telescopic spring 6013 is fixed inside the installation groove 6014. One end of the telescopic spring 6013 is fixed to one side of the movable seat 6012. Multiple groups of telescopic springs 6013 are provided. A telescopic structure is formed between the multiple groups of telescopic springs 6013 and the movable seat 6012. A through hole 6011 is formed at the middle position inside the movable seat 6012. Fixed seats 6010 are fixed to both sides of one end of the movable seat 6012. A sealing cover 609 is hinged at the middle position of the fixed seats 6010. Torsion springs 6015 are fixed to both sides at the middle position of the fixed seats 6010. One end of the torsion spring 6015 is fixed to one side of the fixed seat 6010. The other end of the torsion spring 6015 is fixed to one side of one end of the sealing cover 609. Two groups of shock-absorbing cylinders 601 are provided. The two groups of shock-absorbing cylinders 601 are symmetrically distributed on one side of the fixed block 8;

[0038] Refer to Figures 1-6As shown in the figure: When the upper die 7 punches the lower die 3, the vibration generated by the punching will be transmitted to the workbench 2. When the upper die 7 moves, it will drive the extrusion rubber block 503 to squeeze out the air inside the cavity 505 and squeeze it into the inside of the airbag 604, causing the airbag 604 to expand. Since there is a block on one side of the airbag 604, when the airbag 604 expands, it will expand to one side, thereby pushing the second magnet 605 to move to one side. When the second magnet 605 moves to one side, it will drive the piston 606 to move to one side inside the shock absorber cylinder 601. When the piston 606 moves to one side inside the shock absorber cylinder 601, the hydraulic oil in the inner cavity on one side of the fixed disk 608 inside the shock absorber cylinder 601 will be extracted. Since one end of the sealing cover 609 is inserted into the inside of the through hole 6011 and the through hole 6011 is blocked, at this time, as the piston 606 continues to move, it will drive the movable seat 6012 to move, so that one end of the movable seat 6012 leaves the inside of the through groove 6016. When the movable seat 6012 moves, it will drive the telescopic spring 6013 to stretch, thereby opening the through groove 6016, enabling the hydraulic oil to enter the other cavity 505 inside the shock absorber cylinder 601 through the through groove 6016. At this time, when the vibration is transmitted to the workbench 2, a non-contact buffer layer is formed between the first magnet 602 and the second magnet 605. The repulsive force between the like magnetic poles can form a non-contact suspension gap between the first magnet 602 and the second magnet 605, and the continuous magnetic field force is used to absorb or disperse the vibration energy, thereby reducing the transmission of the vibration force and achieving the effect of preliminary shock absorption. When the second magnet 605 pushes the piston 606 to move back inside the shock absorber cylinder 601 during shock absorption, the movable seat 6012 will return to its original position when the piston 606 is pushed back, blocking the through groove 6016, so that the hydraulic oil can only flow through the through hole 6011, thereby squeezing the hydraulic oil on one side inside the shock absorber cylinder 601 back to its original position through the through hole 6011. When the hydraulic oil passes through the inside of the through hole 6011, it will push the sealing cover 609 to flip to one side. When the sealing cover 609 flips, it will drive the torsion spring 6015 to compress. Since the inner diameter of the through hole 6011 is relatively small, when the hydraulic oil passes through the small hole at high speed, due to the aperture limitation, a local pressure drop is generated, and the oil liquid rubs violently against the hole wall, converting the mechanical vibration energy into heat energy and dissipating it into the environment, thereby reducing the efficiency of energy transmission and significantly weakening the vibration energy, thus achieving the effect of secondary shock absorption. Since the torsion springs 6015 are arranged on both sides of one end of the sealing cover 609, when the hydraulic oil is pushed back to its original position by the piston 606, it will return to its original position under the action of the torsion spring 6015 and block the through hole 6011 for the next operation, finally completing the shock absorption work on the workbench 2, reducing the impact force generated by the vibration from being transmitted to the mold and the workpiece through the workbench 2, resulting in the mold positioning deviation and the workpiece size error increasing, directly affecting the machining accuracy, and thus completing the shock absorption work.
