After moving to a certain position, one side of the knocking plate 410 will abut against one side of the trapezoidal block 413. Under the limiting and squeezing action of the trapezoidal block 413, one end of the knocking plate 410 will rotate downward at the bottom of the extraction box 42 with the first round rod 411 as the center, and the second torsion spring 412 will undergo corresponding deformation. At the same time, the trapezoidal block 413 will also rotate upward in the inner wall of the first cooling box 31 with the second round rod 414 as the center, driving the third torsion spring 415 to Deformation, when the knocking plate 410 rotates to a certain angle, one end will detach from the trapezoidal block 413, and the second torsion spring 412 will drive the knocking plate 410 to reset and knock the camshaft inside the extraction box 42 to make the carbon on its surface shake off. At the same time, the third torsion spring 415 will drive the trapezoidal block 413 to reset, and repeatedly squeeze and limit it through several trapezoidal blocks 413. In the process of the extraction box 42 rising, the knocking plate 410 can be driven to undergo multiple knocking and vibration treatments. Finally, after the extraction box 42 rises to a certain position, it will drive the cooled camshaft to move upward and take it out of the first cooling pool 31, and then the rectangular door 44 will be rotated to a certain position in the rectangular hole 43, so that the camshaft rolls out of the rectangular hole 43 and falls into the collection box 41 for collection, which is convenient for later transportation and processing, thereby improving processing efficiency.

[0055] Reference Figure 1-10 As shown, the present embodiment discloses that the outer surfaces of both ends of the rectangular door 44 are sleeved with first torsion springs 45, and the two ends of the first torsion spring 45 are fixedly connected to the inner wall of the rectangular hole 43 and one side of the rectangular door 44, respectively. By setting the first torsion spring 45, when the extraction box 42 is placed in the bottom of the first cooling pool 31, the rectangular door 44 will be squeezed into the rectangular hole 43 by the inner wall of the first cooling pool 31, driving the first torsion spring 45 to deform. When the extraction box 42 is pulled upward from the first cooling pool 31 to a certain position, when the rectangular door 44 is exposed from the first cooling pool 31, the first torsion spring 45 will reset it and rotate it out of the rectangular hole 43, so that it can be convenient for the camshaft in the extraction box 42 to carry out material unloading without manual operation, saving manpower. The bottom of the extraction box 42 is arranged in an inclined manner, and the bottom of the extraction box 42 is arranged at a side lower than the other side close to the collection box 41. By setting the bottom of the extraction box 42 to an inclined state, after the extraction box 42 is pulled upward to a certain position, the rectangular door 44 is rotated open from the rectangular hole 43, and the camshaft retained on the bottom of the extraction box 42 will slide out from the inclined bottom under the action of gravity, causing it to roll out of the rectangular hole 43, making it easy to enter the collection box 41 for transportation.

[0056] The working principle is as follows: when the forging machine 1 is used to forge the camshaft, a certain amount of cooling water is first added to the first cooling pool 31, and then the cam blank is placed into the lower forging die 5 by means of the feeder, and then the cylinder 6 is started to drive the upper forging die 7 to press down, and the cam blank is forged. After processing, the electric telescopic rod 8 is started to drive the push plate 9 to push the forged camshaft from the lower forging die 5 to the guide plate 22, and then transport it to the two conveying rollers 24 on the conveyor belt 23 for limiting, and the first motor 26 is started to drive the circular shaft 25 to rotate on the base 21, so that the conveyor belt 23 can be driven to rotate in the inner wall of the base 21, so that it drives a number of conveying rollers 24 to follow the corresponding movement, and then drives the gear 28 to move, and the gear 28 rotates on the inner gear ring block 27, driving the conveying roller 24 to rotate, and the conveyed camshaft is evenly turned over and rotated. After being transferred to a certain position, it falls into the extraction box 42 in the first cooling pool 31, and the cooling water will evenly cool its surface. The heated cooling water will be discharged from the outlet pipe 32 into the second cooling pool 33. The semiconductor heat sink 36 at the bottom of the second cooling pool 33 will cool the cooling water inside it. The cooled cooling water will be pumped into the water inlet pipe 35 by the water pump 34, driving the first impeller 37 to rotate, thereby driving the stirring rod 38 to rotate in the second cooling pool 33, stirring the cooling water inside it, and facilitating the cooling water near the semiconductor heat sink 36 and the cooling water at the top. The water is stirred evenly so that it is evenly in contact with the side close to the semiconductor heat sink 36, thereby improving the heat dissipation efficiency of the cooling water. At the same time, it drives the second impeller 310 to rotate, thereby driving the fan blades 311 to rotate inside the wind guide cover 312, sucking air from the water inlet and then discharging it from the air outlet 314, so that it performs preliminary air cooling treatment on the camshaft transported on the conveying roller 24, and then injects it into the water inlet of the first cooling pool 31 for circulating cooling, so that the surface of the camshaft is evenly and quickly cooled in the flowing cooling water, which facilitates the rapid shaping of the camshaft and improves the processing efficiency of the camshaft.When it needs to be taken out after being cooled by running water, the second motor 47 can be started to drive the winding rod 48 to rotate on the bracket 46, and one end of the pull rope 49 can be rolled up, driving the extraction box 42 to move upward, and at the same time driving the knocking plate 410 to move upward. After moving to a certain position, one side of the knocking plate 410 will abut against one side of the trapezoidal block 413. Under the limiting and squeezing action of the trapezoidal block 413, one end of the knocking plate 410 is rotated downward at the bottom of the extraction box 42 with the first round rod 411 as the center, and the second torsion spring 412 is deformed accordingly. At the same time, the trapezoidal block 413 will also rotate upward in the inner wall of the first cooling box 31 with the second round rod 414 as the center, driving the third torsion spring 415 to deform. When the knocking plate 410 rotates to a certain angle, one end will detach from the trapezoidal block 413 The second torsion spring 412 will drive the knocking plate 410 to reset and knock the camshaft inside the extraction box 42, so that the carbon on its surface will fall off. At the same time, the third torsion spring 415 will drive the trapezoidal block 413 to reset, and repeatedly squeeze and limit it through several trapezoidal blocks 413. In the process of the extraction box 42 rising, the knocking plate 410 can be driven to perform multiple knocking and vibration treatments. Finally, after the extraction box 42 rises to a certain position, it will drive the cooled camshaft to move upward and take it out of the first cooling pool 31. When the rectangular door 44 is exposed from the first cooling pool 31, the first torsion spring 45 will reset it and rotate it out of the rectangular hole 43, so that the camshaft will roll out of the rectangular hole 43 under the action of gravity and fall into the collection box 41 for collection, which is convenient for later transportation and processing, thereby improving processing efficiency.
