Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an anti-splash forging press for aluminum alloy die forgings. Background Technology

[0002] In the production process of aluminum alloy die forgings, forging presses play an indispensable role. Their working principle is to apply strong pressure to aluminum alloy billets with the help of hammers, anvils, punches or dies, so as to cause the billets to undergo plastic deformation, thereby obtaining aluminum alloy die forgings that meet specific shape and size requirements. This processing method is widely used in many fields such as aerospace, automobile manufacturing, and electronic equipment. These fields have extremely high requirements for the quality and precision of aluminum alloy die forgings.

[0003] In actual operation, existing aluminum alloy forging presses cause severe plastic deformation of the aluminum alloy billet under immense pressure during forging. Some aluminum alloy material is ejected at high speed as fragments due to uneven stress and die collisions. At the same time, the high-temperature aluminum alloy billet is also prone to generating sparks during forging. These flying fragments and sparks pose a serious threat to the personal safety of operators. If not careful, the fragments may puncture the operator's skin, and the high-temperature sparks may cause burns. In severe cases, they may even cause damage to vital parts such as the eyes. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an anti-splash forging press for aluminum alloy forging parts. This can solve the problem that during the forging operation, due to the severe plastic deformation of the aluminum alloy billet under huge pressure, some aluminum alloy material will be splashed out at high speed in the form of fragments due to uneven force, mold collision and other reasons. At the same time, the high temperature aluminum alloy billet is also very likely to generate sparks during the forging process. These splashed fragments and sparks pose a serious threat to the personal safety of the operators. If not careful, the fragments may puncture the operator's skin, and the high temperature sparks may cause burns. In severe cases, it may even cause damage to important parts such as the eyes.

[0030] Please see Figure 1-4 This utility model provides a technical solution: an anti-splash forging press for aluminum alloy die forgings, including a base 1, a top plate 9 and a sliding mounting seat 10;

[0031] The sliding mounting base 10 is equipped with a splash-proof device;

[0032] The splash-proof device includes an upper mold 15, two clamping and limiting plates 5, and two protective covers 3. Both protective covers 3 are U-shaped. Two T-shaped block grooves 11 are formed on the outer walls of both the front and rear sides of the sliding mounting base 10. Two T-shaped blocks 6 are fixedly connected to the upper outer walls of both protective covers 3. The outer walls of the four T-shaped blocks 6 are slidably connected to the interior of their respective T-shaped block grooves 11. The upper mold 15 is fixedly mounted on the lower surface of the sliding mounting base 10. Two sliding support grooves 16 are formed on the lower surface of both protective covers 3. Sliding supports 4 are slidably connected inside the four sliding support grooves 16. A protective pad is provided at the end of each of the four sliding supports 4 away from the protective cover 3. A buffer spring 18 is provided inside each of the four sliding support grooves 16. The two ends of the four buffer springs 18 are respectively connected to… The inner wall of the corresponding sliding support groove 16 is fixedly connected to one end of the sliding support 4. Limiting block grooves 19 are opened on the outer walls of both sides of the two protective covers 3. The upper mold 15 is located inside the two protective covers 3. The lower surface of the sliding mounting seat 10 has a groove in which a bidirectional threaded rod 20 is rotatably connected. The outer wall of the bidirectional threaded rod 20 is threadedly connected to two clamping limiting plates 5. The upper outer wall of the two clamping limiting plates 5 is fixedly connected to a conical block 13. The lower surface of the sliding mounting seat 10 has two conical block grooves 12. The outer walls of the four conical blocks 13 are slidably connected to the interior of the corresponding conical block grooves 12. The outer walls of the two clamping limiting plates 5 on opposite sides are fixedly connected to two limiting blocks 14. The outer walls of the four limiting blocks 14 are slidably connected to the interior of the corresponding limiting block grooves 19.

[0033] The four support columns at the upper end of the base 1 are fixedly connected to the lower surface of the top plate 9. A cylinder 8 is installed on the upper surface of the top plate 9. The output end of the cylinder 8 extends to the outside of the top plate 9 and is fixedly connected to the upper surface of the sliding mounting seat 10. The four corners of the sliding mounting seat 10 are slidably connected to the outer walls of the four support columns on the base 1. Two slide rods 7 are slidably connected on the top plate 9. The ends of the two slide rods 7 near the sliding mounting seat 10 extend to the outside of the top plate 9 and are fixedly connected to the upper surface of the sliding mounting seat 10. A lower mold 2 is installed on the worktable on the base 1. A motor 17 is installed on one side of the sliding mounting seat 10. The output end of the motor 17 extends to the groove on the lower surface of the sliding mounting seat 10 and is fixedly connected to one end of the bidirectional threaded rod 20.

[0034] Furthermore, when using this device, it is started by connecting an external power source. The aluminum alloy forging is placed on the lower die 2 on the base 1. Then, the cylinder 8 on the top plate 9 is activated. The output end of the cylinder 8 pushes the sliding mounting seat 10, causing it to slide downwards along the support column of the base 1 and the slide rod 7 of the top plate 9. The sliding mounting seat 10 drives the upper die 15 to move downwards. The upper die 15 closes with the lower die 2, applying pressure to the aluminum alloy forging to cause plastic deformation. The impact force generated by forging is partially absorbed by the sliding support 4 and the buffer spring 18. The sliding support 4 slides within the sliding support groove 16, and the buffer spring 18 is compressed or stretched to reduce the vibration of the protective cover 3. The displacement prevents splashes from flying out. Then, when it is necessary to remove the protective cover 3, the output end of the motor 17 drives the bidirectional threaded rod 20 to rotate. Since the bidirectional threaded rod 20 is threadedly connected to the two clamping limit plates 5, and the thread design allows the two clamping limit plates 5 to move relative to each other when the bidirectional threaded rod 20 rotates, when the clamping limit plates 5 move, the upper conical block 13 slides and guides in the conical block groove 12, and the side limit block 14 slides in the limit block groove 19 of the protective cover 3. In this way, the movement of the clamping limit plates 5 causes the limit block 14 to disengage from the inside of the limit block groove 19. Then, the protective cover 3 can be pulled to remove it from the sliding mounting base 10.

[0035] The output end of cylinder 8 in the anti-splash device pushes the sliding mounting seat 10, causing it to slide downward along the support column of base 1 and the slide rod 7 of top plate 9. The sliding mounting seat 10 drives the upper die 15 to move downward, and the upper die 15 closes with the lower die 2, applying pressure to the aluminum alloy forging to cause plastic deformation. The impact force generated by forging is partially absorbed by the sliding support 4 and the buffer spring 18. The sliding support 4 slides in the sliding support groove 16, and the buffer spring 18 is compressed or stretched to reduce the vibration and displacement of the protective cover 3 and prevent splashes from flying out. In this way, the protective cover 3 effectively protects the staff while improving the practicality and safety of the equipment.
