Description

Technical Field

[0001] This utility model relates to the field of forging die technology, specifically a multi-purpose forging die. Background Technology

[0002] Forging dies are specialized tools that can shape billets into forgings. They are essential key process equipment in the production of forgings. They have cavities (also known as die chambers) of a certain shape and size, and their shape and size are all or partly equivalent to the forgings to be manufactured. Through the precise design of the die chamber, forging dies ensure that the forgings achieve the required geometric shape and dimensional accuracy.

[0003] The aforementioned forging dies still have some problems in use. Traditional forging dies suffer from material wear, oxide scale shedding, metal adhesion, and process residue, resulting in debris residue inside the die cavity. This debris can cause surface defects in the forgings, such as pits and scratches. At the same time, debris accumulation accelerates die wear and shortens service life. Generally, the forging process requires stopping the machine to clean the debris, but this greatly affects production efficiency and causes low forging efficiency. Therefore, a multi-purpose forging die is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional forging dies often suffer from material wear, oxide scale shedding, metal adhesion, and process residue, resulting in debris residue inside the die cavity. This debris can cause surface defects in forgings, such as pits and scratches. At the same time, debris accumulation accelerates die wear and shortens service life. Generally, the forging process requires stopping the machine to clean the debris, but this greatly affects production efficiency and causes low forging efficiency. This utility model proposes a multi-purpose forging die.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The multi-purpose forging mold of this utility model includes a frame, a hydraulic cylinder is fixedly connected to the top of the frame, and a lower mold base is fixedly connected to the bottom of the frame. An upper mold base is fixedly connected to the output end of the hydraulic cylinder. A filter box and a high-pressure air pump are fixedly connected to the rear side of the frame. Support plates are provided on both sides of the frame. A dust suction pipe and an air blowing pipe are fixedly connected to the bottom ends of the two support plates, respectively. A pair of pressure rods are fixedly connected to the middle of the support plates. A pair of guide rods are provided through the top of the support plates. A drive motor is fixedly connected to the front side of the filter box.

[0006] Preferably, the filter box is provided with an inlet and an outlet at its upper and lower ends, respectively, and a filter screen is fixedly connected to one side of the filter box. A rotating shaft is movably connected to the center of the filter box, and a cleaning plate is fixedly connected to the outside of the rotating shaft.

[0007] Preferably, the suction pipe is fixedly connected to the feed inlet at the top of the filter box, the air blowing pipe is fixedly connected to the output end of the high-pressure air pump, and the suction pipe and the air blowing pipe are symmetrically arranged. The input end of the high-pressure air pump is fixedly connected to the side of the filter box near the filter screen.

[0008] Preferably, the top surface of the pressure rod is inclined, and the pressure rod is adapted to the upper mold base.

[0009] Preferably, the guide rod is fixedly connected to the frame, and a return spring is sleeved on the outer side of the guide rod. The two ends of the return spring are fixedly connected to the support plate and the end of the guide rod away from the support plate, respectively.

[0010] Preferably, the output end of the drive motor is fixedly connected to the rotating shaft, and one end of the cleaning plate on the outer side is in contact with the inner surface of the filter box.

[0011] The advantages of this utility model are: 1. This utility model uses the upper die seat to press the inclined surface of the pressure rod, causing the pressure rod to move the support plate outward, thereby moving the dust suction pipe and the air blowing pipe away from the die. After forging is completed, the upper die seat rises and resets, and then the forging is removed. The pressure rod loses its limiting component, and under the action of the reset spring and guide rod, the support plate resets, thereby moving the dust suction pipe and the air blowing pipe closer to the die. At the same time, the high-pressure air pump is started, and the high-pressure air pump delivers high-pressure gas to the air blowing pipe to blow away the residue inside the die cavity of the lower die seat. At the same time, the dust suction pipe generates suction to absorb the debris and residue blown by the air blowing pipe. Then the residue enters the filter box through the dust suction pipe and is filtered by the filter screen. This application automatically completes the residue cleaning work inside the die cavity by setting a slag removal component with linkage effect, which not only ensures forging efficiency, but also reduces residue residue and improves the forging effect of the forging. 2. This utility model uses a drive motor to rotate a cleaning plate inside the filter box. When the cleaning plate passes the filter screen, it cleans the residue filtered inside the screen, reducing clogging. As the shaft continues to rotate, when two adjacent plates are located on either side of the discharge port, a partition space is formed. At this time, the suction airflow generated by the high-pressure air pump is separated from the discharge port, allowing the residue to be discharged directly from the discharge port. The slag discharge assembly can promptly discharge the concentrated residue, reducing clogging, ensuring smooth airflow, and enabling the residue cleaning process to proceed normally.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 one Figure 5 As shown, a multi-purpose forging mold includes a frame 1. A hydraulic cylinder 2 is fixedly connected to the top of the frame 1, and a lower mold base 3 is fixedly connected to the bottom of the frame 1. An upper mold base 4 is fixedly connected to the output end of the hydraulic cylinder 2. A filter box 5 and a high-pressure air pump 6 are fixedly connected to the rear side of the frame 1. Support plates 9 are provided on both sides of the frame 1. A dust suction pipe 7 and an air blowing pipe 8 are fixedly connected to the bottom ends of the two support plates 9 respectively. A pair of pressure rods 10 are fixedly connected to the middle of the support plates 9. A pair of guide rods 12 are provided through the top of the support plates 9. A drive motor 11 is fixedly connected to the front side of the filter box 5. During operation, traditional forging die materials wear, oxide scale shedding, metal adhesion, and process residues can cause debris residue inside the die cavity. This debris can lead to surface defects in the forgings, such as pits and scratches. At the same time, debris accumulation can accelerate die wear and shorten service life. Generally, the machine needs to be stopped during the forging process to clean the debris, but this greatly affects production efficiency and causes low forging efficiency. After forging is completed, the hydraulic cylinder 2 drives the upper die holder 4 to rise and reset, and then the forging is taken out. At the same time, the high-pressure air pump 6 is started. The high-pressure air pump 6 delivers high-pressure gas to the air blowing pipe 8 to blow away the residue inside the die cavity of the lower die holder 3.

[0017] Furthermore, the filter box 5 is provided with an inlet 14 and an outlet 15 at its upper and lower ends, respectively, and a filter screen 16 is fixedly connected to one side of the filter box 5. A rotating shaft 17 is movably connected in the center of the filter box 5, and a cleaning plate 18 is fixedly connected to the outside of the rotating shaft 17. During operation, when two adjacent cleaning plates 18 are located between the feed inlet 14 and the filter screen 16 respectively, the suction pipe 7 generates suction to absorb the debris and residue blown by the air blowing pipe 8. Then, the residue enters the filter box 5 through the suction pipe 7 and is filtered by the filter screen 16.

[0018] Furthermore, the suction pipe 7 is fixedly connected to the feed inlet 14 at the upper end of the filter box 5, the air blowing pipe 8 is fixedly connected to the output end of the high-pressure air pump 6, and the suction pipe 7 and the air blowing pipe 8 are symmetrically arranged. The input end of the high-pressure air pump 6 is fixedly connected to the side of the filter box 5 near the filter screen 16. During operation, when two adjacent parts are located on either side of the discharge port 15, they form a partition space. At this time, the suction airflow generated by the high-pressure air pump 6 is separated from the position of the discharge port 15, and the residue is directly discharged from the discharge port 15.

[0019] Furthermore, the top surface of the pressure rod 10 is inclined, and the pressure rod 10 is adapted to the upper mold base 4; During operation, the mold blank is placed inside the lower mold base 3, and then the hydraulic cylinder 2 drives the upper mold base 4 to descend, forging the mold blank into a pot body. During this process, the upper mold base 4 presses the inclined surface of the pressure rod 10, causing the pressure rod 10 to drive the support plate 9 to move outward, thereby moving the dust suction pipe 7 and the air blowing pipe 8 away from the mold.

[0020] Furthermore, the guide rod 12 is fixedly connected to the frame 1, and a return spring 13 is sleeved on the outer side of the guide rod 12. The two ends of the return spring 13 are fixedly connected to the support plate 9 and the end of the guide rod 12 away from the support plate 9, respectively. During operation, the moving compression return spring 13 of the support plate 9 deforms, and after the upper mold base 4 rises and resets, the pressure rod 10 loses its limiting component. Under the action of the return spring 13 and the guide rod 12, the support plate 9 resets, thereby bringing the dust suction pipe 7 and the air blowing pipe 8 closer to the mold.

[0021] Furthermore, the output end of the drive motor 11 is fixedly connected to the rotating shaft 17, and the outer end of the cleaning plate 18 is in contact with the inner surface of the filter box 5. During operation, the drive motor 11 is started, causing the rotating shaft 17 to drive the cleaning plate 18 to rotate inside the filter box 5. When the cleaning plate 18 passes the filter screen 16, it cleans the residue filtered inside the filter screen 16, reducing the occurrence of clogging problems.

[0022] Working principle: The mold blank is placed inside the lower mold base 3. Then, the hydraulic cylinder 2 drives the upper mold base 4 to descend, forging the mold blank into a pot body. During this process, the upper mold base 4 presses the inclined surface of the pressure rod 10, causing the pressure rod 10 to move the support plate 9 outward. The movement of the support plate 9 compresses the return spring 13, causing it to deform. This, in turn, moves the suction pipe 7 and the air blowing pipe 8 away from the mold. After forging is completed, the hydraulic cylinder 2 drives the upper mold base 4 to rise and return to its original position. Then, the forging is removed, and the pressure rod 10 loses its limiting component. The return spring 13 and the guide rod 12... Under the action of the suction pipe 7, the support plate 9 is reset, which brings the suction pipe 7 and the air blowing pipe 8 closer to the mold. At the same time, the high-pressure air pump 6 is started, which delivers high-pressure gas to the air blowing pipe 8 to blow away the residue inside the mold cavity of the lower mold base 3. Meanwhile, the suction pipe 7 generates suction to absorb the debris and residue blown away by the air blowing pipe 8. Afterward, the residue enters the filter box 5 through the suction pipe 7 and is filtered by the filter screen 16. The residue cleaning work inside the mold cavity is automatically completed, which not only ensures forging efficiency but also reduces residue residue and improves the forging effect of the forging.

[0023] During the residue cleaning process, the drive motor 11 is started, causing the rotating shaft 17 to drive the cleaning plate 18 to rotate inside the filter box 5. When the cleaning plate 18 passes the filter screen 16, it cleans the residue filtered inside the filter screen 16, reducing the occurrence of clogging problems. As the rotating shaft 17 continues to rotate, when two adjacent shafts are located on both sides of the discharge port 15, a partition space is formed. At this time, the suction airflow generated by the high-pressure air pump 6 is separated from the position of the discharge port 15, and the residue is directly discharged from the discharge port 15, ensuring the normal operation of the residue cleaning work.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
