Description

Technical Field

[0001] The present invention relates to the technical field of forging, in particular to a forging device for mechanical precision parts. Background Art

[0002] Forging uses a forging machine to apply pressure to a metal blank, causing it to plastically deform, thereby improving the metal's structure and mechanical properties. Compared to casting, forging can eliminate defects introduced during the metallurgical process, such as as-cast porosity, and optimize the microstructure, resulting in forgings with superior mechanical properties compared to castings of the same material. Consequently, forging is widely used in the production and processing of mechanical components, while die casting can achieve higher-precision component processing.

[0003] In the prior art, after the forging equipment used for mechanical precision parts completes processing, the workpiece forged inside the mold is removed by clamping or pushing it out from the bottom. However, this process can easily damage the surface of the workpiece. On the other hand, oxide scale will be generated on the surface of the high-temperature metal during the forging process. The oxide scale is pressed into the metal matrix and easily forms folding defects, which reduces the quality of the finished product. In the conventional forging process, once the oxide scale is stuck inside the mold, it is difficult to discharge it quickly. Even if the oxide scale is discharged at the same time as the workpiece, it is easy to damage the high-temperature workpiece surface again during the subsequent transportation process.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a forging device for mechanical precision parts, comprising a forging device body, the forging device body comprising a forging mechanism 1, a forming assembly 2, a pushing mechanism 3 and a discharge mechanism 4, the bottom of the discharge mechanism 4 is provided with a bottom plate 14, the surface of the bottom plate 14 is provided with a waste trough 15 and a discharge trough 16, the waste trough 15 is used to collect the oxide waste generated during the forging process, the discharge trough 16 is used to receive the workpiece after forging, the rear end of the bottom plate 14 is welded with a back plate 22, the back plate 22 A forging mechanism 1 is mounted on the surface of the back plate 22. A fixed plate 13 is welded to the inner side of the back plate 22. A vertical plate 5 is welded to the edge of the bottom plate 14. A forming assembly 2 is mounted between the vertical plate 5 and the fixed plate 13. A mold 8 is disposed in the middle of the forming assembly 2. An ejection mechanism 3 is screwed to the bottom of the mold 8. A motor 6 is screwed to one end of the forming assembly 2. The forming assembly 2 is rotated by the motor 6. A rotating plate 18 is mounted between the discharge chute 16 and the waste chute 15. The forming assembly 2 is mounted above the rotating plate 18. This forging equipment is used to perform forging processing on precision mechanical parts and to implement the subsequent discharge process.

[0029] When the present invention is used, the workpiece substrate heated at high temperature is placed in the forming component 2 and supported by the cavity 9. At this time, the substrate inside the mold 8 can be forged by controlling the forging mechanism 1 at the top until the molding is completed inside the mold 8. After forging is completed, the forging mechanism 1 can be controlled to move upward, and the motor 6 at one end of the forming component 2 can be controlled to run, driving the mold 8 to flip, and finally the entire forming component 2 is rotated to face the bottom, and the ejection mechanism 3 is rotated to the upper position. In this state, the ejection mechanism 3 can be triggered with the help of the forging mechanism 1 to push out the workpiece inside the cavity 9, and at the same time, the oxide scale adhered to the inside of the cavity 9 is discharged and cleaned. At this time, the workpiece and the oxide scale can be pushed into the discharge mechanism 4 at the bottom, and the discharge mechanism 4 is used to cooperate with the limit lever 11 to block the workpiece first until the oxide scale part is discharged, and then the motor 6 is continued to be controlled to rotate, and the workpiece is transported to the discharge trough 16 to complete the separation process.

[0030] In this embodiment, the forming assembly 2 includes a mold 8, a drive shaft 7, and a support column 12. The motor 6 is screwed to the top of the surface of the vertical plate 5. A cavity 9 is provided on the inner side of the mold 8. A panel 10 is welded to the side of the mold 8. The output end of the motor 6 is plugged with the drive shaft 7. The end of the drive shaft 7 is fixedly connected to the surface of the panel 10. A limit stop rod 11 is plugged into the top of one side of the panel 10. The rear end of the panel 10 is integrally formed with a support column 12. A docking sleeve 26 is provided on the surface of the fixed plate 13. The end of the support column 12 is embedded in the interior of the docking sleeve 26. There are three limit stop rods 11, and the spacing between adjacent limit stop rods 11 is the same. The forming assembly 2 can rotate by controlling the ejection mechanism 3, so that the workpiece and the generated oxide scale can be efficiently discharged, and the processing efficiency is high. The blocking structure on the side and the buffer structure at the bottom can reduce the probability of damage to the workpiece when it is removed.

[0031] Specifically, the workpiece substrate after high-temperature heating is placed in the cavity 9. In the initial state, the cavity 9 on the inner side of the mold 8 is exposed upward, and the ejection mechanism 3 is in the lower area. The inner bottom of the cavity 9 is flush with the bottom area through the support plate 35. Therefore, in this state, the forging mechanism 1 on the top is directly started, and the forging hammer head 25 at the bottom can be forged toward the bottom by extending the hydraulic rod 24, thereby achieving the purpose of forging the material inside the cavity 9. During the forging process, the entire mold 8 is always supported by the side panels 10, and the two ends are fixed by the drive shaft 7 and the support column 12 respectively to ensure that it remains stable during the forging process.

[0032] In this embodiment, the ejection mechanism 3 includes a piston sleeve 27, a push plate 32, and a support plate 35. An outer convex ring 28 is integrally formed on the outer end of the piston sleeve 27. A guide hole 29 is formed on the surface of the outer convex ring 28. A first spring rod 33 is inserted into the guide hole 29. One end of the first spring rod 33 is welded to the surface of the push plate 32. A push rod 31 is integrally formed in the middle of the push plate 32. A piston plate 30 is integrally formed at the end of the push rod 31. The piston plate 30 is embedded in the interior of the piston sleeve 27. A push channel 34 is integrally formed on the other end of the piston sleeve 27. The support plate 35 is embedded in the push channel 34. An inner convex ring 36 is integrally formed on the inner wall of the pushing channel 34. A telescopic sleeve 37 is welded to the surface of the inner convex ring 36. A second spring rod 38 is inserted into the interior of the telescopic sleeve 37. The other end of the second spring rod 38 is welded to the bottom of the support plate 35. An exhaust hole 39 is provided on the side of the support plate 35. One end of the support plate 35 is closed and the other end is open. The closed end of the support plate 35 is embedded in the interior of the mold cavity 9. The piston plate 30, the push rod 31, and the push plate 32 are all provided with air intake holes. The forging mechanism 1 includes a top plate 23, a hydraulic rod 24, and a forging hammer 25. The top plate 23 is welded to the surface of the back plate 22. The hydraulic rod 24 is screwed to the bottom of the top plate 23. The forging hammer 25 is screwed to the bottom end of the hydraulic rod 24. After the hydraulic rod 24 is extended, the forging hammer 25 is pressed against the surface of the die 8 or the surface of the push plate 32 , and the hydraulic rod 24 always moves up and down along the central axis of the piston sleeve 27 .

[0033] The ejection mechanism 3 can efficiently eject the workpiece and the generated oxide scale, preventing the workpiece from being stuck and the oxide scale waste from partially adhering to the inside of the mold 8 and being unable to be completely ejected. This can prevent the accumulated and adhered oxide scale waste from damaging the subsequent high-temperature metal surface injected. The ejection process still relies on the forging mechanism 1 to provide thrust, thereby improving the utilization rate of the forging mechanism 1.

[0034] Specifically, after the forging is completed, the motor 6 is controlled to operate, and the entire forming assembly 2 is driven to rotate by the drive shaft 7. During the rotation, the workpiece inside the cavity 9 gradually rotates from vertically upward to vertically downward. During this process, if the workpiece directly breaks away and falls, it will first be blocked by the limit lever 11 and finally fall onto the discharge mechanism 4 at the bottom. If the workpiece is stuck in the cavity 9 at this time and cannot be discharged directly, the subsequent auxiliary discharge process can be completed by the ejection mechanism 3. During this process, since the ejection mechanism 3 has been rotated to a vertically upward position, after the hydraulic rod 24 is started, the forging hammer 25 at the bottom can be slowly moved down again until it rests on the push plate 32. The piston plate 30 is pushed by the push plate 32 and the push rod 31, so that the air inside the piston sleeve 27 can be compressed and the support plate 35 can be pushed toward the inside of the cavity 9. With the help of this ejection effect, the stuck workpiece can be discharged. Once the support plate 35 moves into the interior of the cavity 9 and exposes the exhaust hole 39, the high-pressure airflow inside the piston sleeve 27 can be ejected from the exhaust hole 39 to the surrounding areas, and the oxide scale adhered to the inside of the cavity 9 can be cleaned with the help of this high-pressure airflow.

[0035] In this embodiment, the waste trough 15 and the discharge trough 16 are separated by a partition. An arc spring 21 is welded to the bottom of the rotating plate 18. One side of the discharge trough 16 is inclined, and the bottom of the arc spring 21 is welded to the inclined surface of the discharge trough 16. A fixed end plate 17 is welded to the surface of the bottom plate 14. One end of the rotating plate 18 is connected to the inner wall axis of the fixed end plate 17. A movable end plate 19 is welded to the side of the rotating plate 18. A linkage rod 20 is inserted into the top of the movable end plate 19, and the limit stop rod 11 is used to abut the surface of the linkage rod 20. The forging equipment is provided with a discharge mechanism 4 at the bottom. The discharge mechanism 4 cooperates with the limit stop rod 11 in the forming assembly 2 to discharge the oxide scale waste part first while the workpiece is blocked, and then the workpiece is transported separately, thereby achieving the separation effect between the waste and the workpiece.

[0036] Specifically, during the rotation of the forming component 2, the side limit stop rod 11 will also rotate and press against the side of the linkage rod 20 below to block the entire rotating plate 18. Therefore, even if the workpiece inside the cavity 9 falls, the linkage rod 20 can still be blocked and restricted, and the rotating plate 18 cannot be rotated toward the bottom due to the downward pressure of the workpiece. In this state, the arc spring 21 at the bottom can be used to keep the rotating plate 18 in a tilted state. Therefore, the oxide waste falling from the cavity 9 can be discharged toward the inside of the waste trough 15 along the tilt angle of the rotating plate 18. After the waste is discharged, the motor 6 can be started again until the limit stop rod 11 passes over the linkage rod 20. At this time, the blocking of the linkage rod 20 can be released. Therefore, in this state, the rotating plate 18 is pressed down by the workpiece, causing the arc spring 21 to be compressed, and the originally tilted end is flipped downward, and finally the workpiece pressed on the surface is guided to the inside of the discharge trough 16 at the other end for discharge.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
