The clamp rods 72 are used to fix the camshaft. A gear rod 71 is slidably connected to the rotating mounting plate 62. The gear rod 71 is made of iron. A column gear 73 is fixedly connected to each clamp rod 72.

[0044] The locking components include a magnet block 81, a locking block 82, a return spring 83 and a limit block 84. A plurality of magnet blocks 81 are fixedly connected to the lifting plate 63.

Two return springs 83 are connected between each locking block 82 and the rotating mounting plate 62. A plurality of limit blocks 84 are connected to the rotating mounting plate 62 by bolts.

[0045] At first, the gear rod 71 is locked by the limit column of the block 82, and the user places the heated camshaft raw material in the low-precision forging groove on the fixed forging die 4. Then, the user controls the telescopic rod of the forging hydraulic press 2 to extend. The extension of the telescopic rod of the forging hydraulic press 2 will drive the movable forging die 3 to move toward the direction close to the fixed forging die 4, so that the movable forging die 3 will forge the camshaft to complete the rough forging of the camshaft. Then, the user controls the telescopic rod of the forging hydraulic press 2 to retract. The retraction of the telescopic rod of the forging hydraulic press 2 drives the movable forging die 3 to reset. After the telescopic rod of the forging hydraulic press 2 is reset to the initial position, it continues to retract.

The rod 72 will limit the camshaft, and the lifting plate 63 will continue to move, which will drive the camshaft to move together, so that the camshaft will be separated from the fixed forging die 4. After the camshaft and the fixed forging die 4 are separated, the telescopic rod of the forging hydraulic press 2 will no longer shrink, and the user will control the output shaft of the servo motor 5 to rotate 90 degrees. The rotation of the output shaft of the servo motor 5 will drive the rotating mounting plate 62 to rotate 90 degrees. The rotation of the rotating mounting plate 62 will drive the lifting plate 63 and the camshaft to rotate together, so that the camshaft will move to the next forging groove with higher precision. Then, the user will control the extension of the telescopic rod of the forging hydraulic press 2, and the extension of the telescopic rod of the forging hydraulic press 2 will drive the movable forging die 3 and the transmission rod 64 to move. The movable forging die 3 moves to forge the camshaft, and the transmission rod 64 moves The lifting plate 63 and the magnet block 81 are driven to reset, and the magnet block 81 resets and drives the gear rod 71 to reset. After the gear rod 71 moves to the initial position, it is resisted by the limit block 84, and the camshaft falls into the forging groove. The magnet block 81 continues to reset and will disengage from the gear rod 71, the lifting plate 63 resets and disengages from the locking block 82, the reset spring 83 resets and drives the locking block 82 to reset, the locking block 82 resets and limits the gear rod 71, the lifting plate 63 continues to reset, the column gear 73 and the gear rod 71 mesh, the column gear 73 reverses and resets, the column gear 73 reverses and drives the clamping rod 72 to reset, the lifting plate 63 further resets and disengages from the camshaft, and then the movable forging die 3 continues to forge the camshaft to complete the secondary forging, and this reciprocating twice, the camshaft will be gradually forged three times.The accuracy of the three forgings is gradually improved. After the third forging is completed, the telescopic rod of the forging hydraulic press 2 returns to the initial position, and the user takes out the camshaft that has been forged to complete the forging process. In this way, the camshaft can be quickly moved to forging grooves of different accuracy, thereby improving the forging efficiency.

[0046] Embodiment 2: Based on embodiment 1, Figure 16-Figure 20 As shown, it also includes a blowing component. The mounting frame 1 is provided with a blowing component, which is used to remove impurities on the movable forging die 3, the fixed forging die 4 and the forging camshaft. The blowing component includes a blowing frame 91, an air guide pipe 92, a column gear 93, a gear rod 94 and a guide frame 95. Two blowing frames 91 are rotatably connected to the mounting frame 1. The two blowing frames 91 are symmetrically arranged. The interiors of the two blowing frames 91 are both hollow. The two blowing frames 91 are fixedly connected with an air guide pipe 92, the air guide pipe 92 is connected to the interior of the blowing frame 91, and the two blowing frames 91 are fixedly connected with a column gear 93.

The scraper rods 102 are used to scrape impurities on the impurity discharge frame 101.

[0050] Initially, the blowing frame 91 is located between the movable forging die 3 and the fixed forging die 4. Before forging the camshaft, the user introduces high-temperature gas into the blowing frame 91 through the air guide pipe 92. The high-temperature gas is sprayed toward the forging grooves of the movable forging die 3 and the fixed forging die 4 through the blowing holes of the blowing frame 91, thereby blowing away the impurities in the forging grooves. During the extension of the telescopic rod of the forging hydraulic press 2, the guide frame 95 is driven to move. The movement of the guide frame 95 will squeeze the gear rod 2 94, so that the gear rod 2 94 will extend out of the mounting frame 1. The movement of the gear rod 2 94 will mesh with the column gear 2 93. The rotation of the column gear 2 93 will drive the blowing frame 91 to rotate and move out of the mounting frame 1. During the retraction of the telescopic rod of the forging hydraulic press 2, the telescopic rod of the forging hydraulic press 2 is reset to drive the guide frame 95 to reset. The guide frame 95 is restored. The rotation of the rotating frame 61 drives the impurity discharge frame 101 to rotate. The rotation of the impurity discharge frame 101 will move the impurities dropped on the impurity discharge frame 101 to the impurity discharge port of the mounting frame 1. The impurities on the impurity discharge frame 101 are blocked by the scraper rod 102, so that the impurities are discharged from the mounting frame 1. In this way, the impurities forged on the camshaft can be discharged from the forging die in time, thereby improving the forging accuracy of the camshaft.

[0051] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
