[0047] As attached Figure 1 To be continued Figure 11 As shown, in one embodiment of the present invention, the specific production process is as follows:
[0048] ① Material heating: Select a suitable forging material and heat it;
[0049] ② Upsetting: The heated forging material is placed in the middle of the forging table 2, and the forging material is forged by the forging pressure shaft 16, so that the height of the forging material is reduced and the cross-section is increased;
[0050] ③ Punching: Punching holes in the middle of the forging material after it has been upsetting using a suitable punching shaft;
[0051] ④ Rolling and expanding: The split rolling roller 8, which is slidably connected to the upper part of the rolling and expanding table 4, rolls and expands the forging material that has been punched;
[0052] ⑤ Die forging: The rolled and expanded forging material is transferred to the die forging table 9, and the forging material is extruded and formed by the lower die 11 and the upper die 13.
[0053] Working principle
[0054] When using this invention, the worker selects a suitable forging material, heats it, and then places the heated forging material in the middle of the forging table 2.
[0055] Next, the forging material is forged by the forging pressure plate 161 at the bottom of the forging pressure shaft 16, which reduces the height of the forging material and increases its cross-section. Then, a suitable punching shaft punches a hole in the middle of the upsetting forging material. The forging pressure plate 161 strikes the punching shaft to impact the forging material. The excess material in the middle of the forging material is impacted and squeezed into the punching platform 3 under the impact force. The punching spring 31 at the bottom of the punching platform 3 is squeezed and deformed. At the end of the impact, the punching spring 31 returns to its original position and ejects the excess material.
[0056] Then, the detachable rolling roller 8, which is slidably connected to the upper part of the rolling table 4, rolls and expands the punched forging. Motor 1 42 starts, driving the lifting screw 43 to rotate. The lifting screw 43 drives the slider 44 to move downward to a suitable position. Motor 2 5 at the front end of the slider 44 starts, driving the rolling screw 6 to rotate. The rolling screw 6 drives the rolling slider 7 to reciprocate back and forth. At the same time, motor 3 71 starts, driving the insertion shaft port 72 to rotate. The insertion shaft port 72 drives the detachable rolling roller 8 to rotate, and the detachable rolling roller 8 begins to roll the forging. Before the rolling operation, rotating the appropriate detachable rolling roller 8 compresses the compression springs 82 at the connecting ends 81 of the rolling rollers on both sides, inserting the detachable rolling roller 8 into the insertion shaft port 72 and connecting it to the rolling slider 7.
[0057] The rolled and expanded forging material is transferred to the die forging table 9, and the forging material is extruded and formed by the lower die 11 and the upper die 13.
