[0021] It also includes a telescopic part 4, a slide plate 5, an electric push rod 6, an electric clamp 7 and a liquid spraying pipe 8; the telescopic part 4 is bolted inside the outer shell 1; the slide plate 5 is bolted on the telescopic part of the telescopic part 4, and the outer shell 1 is provided with a slide groove 1003, and the slide plate 5 slides in the slide groove 1003; the slide plate 5 is fixedly connected to five electric push rods 6 distributed on the left and right; an electric clamp 7 is fixedly connected to the telescopic part of each electric push rod 6, and the extruder 2 is located in front of the electric clamp 7; four liquid spraying pipes 8 are fixedly connected to the outer shell 1, and each liquid spraying pipe 8 is located directly above the corresponding extrusion head 3; a hot upsetting bottom die is provided on the inner rear side of the outer shell 1, and there are four bottom dies in total, and each bottom die groove is provided with a push-out member 1004, and each push-out member 1004 is directly opposite to the corresponding extrusion head 3.

[0022] A filter is provided in the spray pipe 8, through which the coolant entering the spray pipe 8 is filtered to prevent impurities in the coolant from adhering to the extrusion head 3 when the coolant cools the extrusion head 3, causing the impurities to be squeezed into the raw material by the extrusion head 3.

[0023] It also includes a flushing pipe 9; four flushing pipes 9 are installed in the outer shell 1, and each flushing pipe 9 is located directly above the corresponding ejection member 1004, and the nozzle of each flushing pipe 9 faces the corresponding extrusion head 3.

[0024] It also includes an injection pipe 10; four injection pipes 10 are installed in the outer shell 1, and each injection pipe 10 is located directly below the corresponding ejection member 1004, and the nozzle of each flushing pipe 9 faces the corresponding extrusion head 3.

[0025] A filter is also provided inside the flushing pipe 9, which intercepts impurities in the clean water in the flushing pipe 9 to prevent the impurities in the clean water from adhering to the surface of the extrusion head 3, thereby causing the extrusion head 3 to extrude the adhered impurities to the surface of the raw material, affecting the molding quality of the hot forging.

[0026] A filter is provided in the jet pipe 10 to intercept impurities in the air, thereby preventing the impurities carried in the air from adhering to the surface of the extrusion head 3 soaked in the coolant, causing the impurities to be squeezed by the extrusion head 3 to the surface of the raw material, thereby affecting the quality of the hot forging after molding.

[0027] Here is how the above example works:

[0028] When in use, the external feeding device is controlled to feed the cylindrical raw material heated to the processing temperature from the feed port 1001. At the same time, the initial state is as follows Figure 1 As shown, the first electric gripper 7 on the far left is opened, at which time the electric gripper 7 will not block the raw material, and then the external feeding device continues to feed the raw material to the right, so that the raw material is aligned with the first electric gripper 7 on the far left, and then the electric gripper 7 is controlled to close to clamp the raw material, and then the telescopic member 4 is controlled to drive the slide plate 5, the electric push rod 6 and the electric gripper 7 to be pulled synchronously in the direction of the discharge port 1002, and when the first electric gripper 7 on the far left aligns the clamped raw material with the first extrusion head 3 on the far left, the raw material is also aligned with the bottom mold placed inside the outer shell 1, and then the telescopic member 4 stops working, and then the electric push rod 6 of the first electric gripper 7 on the far left is controlled to retract, pulling the electric gripper 7 to move backward, so that a local area of ​​the raw material enters the bottom mold, and the ejection member 1004 in the bottom mold moves synchronously and retracts to the end to form a complete hot upsetting bottom mold; when the local area of ​​the raw material is The raw material is fed into the bottom die, and then the electric gripper 7 is controlled to open and release the grip on the raw material. At this time, the raw material is restricted by the bottom die and will not fall due to the opening of the electric gripper 7. Then the extrusion head 3 starts to move toward the bottom die to prepare for shaping. The movement speed of the extrusion head 3 is not very fast, so the electric push rod 6 of the first electric gripper 7 on the far left is controlled to push the electric gripper 7 connected to it to move forward and reset. At the same time, the telescopic part 4 is controlled to push the slide plate 5, the electric push rod 6 and the electric gripper 7 to move to the left, so that the first electric gripper 7 on the far left is reset. Then the external feeding device continues to convey the second raw material to align it with the first electric gripper 7 on the far left; at this time, the second electric gripper 7 from left to right will replace the first electric gripper 7 on the far left to align with the first raw material in the above-mentioned bottom die in an open posture. After the adjustment is completed, the first extrusion head 3 on the far left performs hot upsetting and shaping on the first raw material.

[0029] After the first extrusion head 3 on the far left has hot-forged the first raw material, the extruder 2 is controlled to drive the first extrusion head 3 on the far left to move forward and reset. During the reset process, the second electric push rod 6 and the second electric clamp 7 from left to right are aligned with the first raw material. Therefore, it is necessary to control the second electric push rod 6 to pull the second electric clamp 7 to move backward so that the first raw material is located in the middle of the second electric clamp 7. At the same time, the ejection piece 1004 in the bottom die is controlled to push the extruded first raw material forward, but the raw material has not completely left the bottom die. Then the electric clamp 7 is controlled to perform a clamping action, and at this time, the first electric clamp 7 on the far left clamps the second raw material transported by the external feeding device The second electric gripper 7 from left to right moves the first raw material after extrusion, and then controls the second electric push rod 6 to push the second electric gripper 7 to move forward, so that the second electric gripper 7 drives the clamped first raw material to move forward synchronously, so that the extruded first raw material completely leaves the bottom die, and then controls the telescopic member 4 to pull the slide plate 5, the electric push rod 6 and the electric gripper 7 to move to the right, so that the first electric gripper 7 on the far left moves the clamped second raw material to the bottom die just aligned with the first raw material, and the second electric gripper 7 from left to right aligns the extruded first raw material with the second bottom die from left to right, aligns with the second extrusion head 3 from left to right, and then performs the second hot upsetting treatment.

[0030] In this way, the raw material piece passes through all the extrusion heads 3 from left to right in sequence, so that multiple extrusion heads 3 of different shapes perform continuous hot upsetting shaping on the raw material piece in sequence, thereby obtaining a finished product, so that the hot upsetting parts with more complex shapes can be deformed in stages, and finally form a more complex shape. For example, the hot upsetting bevel gear can be disassembled into the following steps in the molding sequence, which is to carry out raw material compaction, initial taper, stable taper, tooth groove formation, etc. in sequence. Originally, it was necessary to manually transfer the raw material piece between multiple hot upsetting dies, so that multiple sets of hot upsetting dies are close to each other. Arrange and then use the electric gripper 7 to transfer, the production rhythm is stable and effective, which can greatly reduce the manual alignment of the mold, the insertion of the mold and other operations, as well as the time for misoperation and correction of misoperation, and improve production efficiency; when the rightmost electric gripper 7 takes the extruded raw material from, it will move to the top of the discharge port 1002 in the contracted state of the telescopic member 4, and the electric gripper 7 directly releases the grip of the finished product, so that it falls to the external transport device at the discharge port 1002, and moves from the discharge port 1002 to the next processing step. During the entire hot upsetting process, the spray pipe 8 will continue to spray coolant to cool the extrusion head 3 to prevent overheating.

[0031] It is taken into consideration that, since oxidized impurity debris will be generated on the surface of the raw material during the hot upsetting process, and when the extrusion head 3 hot upsets the raw material, the oxidized impurity debris has a probability of adhering to the extrusion head 3, and the coolant sprayed from the spray pipe 8 cannot flush the inner side of the extrusion head 3. When a certain amount of oxidized impurity debris accumulates, the size of the extrusion head 3 will deviate, which will affect the dimensional accuracy of the hot-forged part after forming. Therefore, after working for a period of time, it is necessary to stop the machine for maintenance and cleaning. During maintenance, all structures are restored to their initial state. At this time, the electric gripper 7 will not block the flushing pipe 9. Subsequently, the external water pump connected to the flushing pipe 9 is controlled to start, so that the external water pump sprays the cleaning liquid from the flushing pipe 9, thereby flushing the inside of the extrusion head 3 with clean water to flush the adhered oxidized impurity debris. After flushing, the external air pump connected to the jet pipe 10 is controlled to start, so that the external air pump sprays hot air from the jet pipe 10, thereby quickly drying the cleaned extrusion head 3, thereby completing the maintenance work.
