[0024] like Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the forging assembly 130 includes a forging table 131, which is fixed on the inner wall of the forging box 110, and transfer grooves are provided on both sides of the forging table 131 close to the first conveying member 121 and the second conveying member 122. The two transfer grooves are respectively installed with a first conveying wheel 132 and a second conveying wheel 133. The first conveying wheel 132 and the second conveying wheel 133 are both driven by a motor. The first conveying wheel 132 is used to convey the lower die 302 located on the first conveying member 121 to the intermittent assembly 230 and forge it through hydraulic equipment.

The first elastic guide plate 134 is located on one side of the first conveying wheel 132, and the second elastic guide plate 135 is located on one side of the second conveying wheel 133.

[0025] Specifically, the first conveying member 121 conveys the lower die 302 to the interior of the forging box 110. When it reaches the opening of the forging table 131, the first conveying wheel 132 conveys the lower die 302 to the work station of the intermittent component 230. The intermittent component 230 automatically sends the lower die 302 to the bottom of the hydraulic equipment, and forges it through the upper die 301. Finally, the forged lower die 302 is conveyed to the second conveying member 122 by the second conveying wheel 133, and then conveyed to the outside of the forging box 110 by the second conveying member 122.

[0026] like Fig. 9 As shown, the drive assembly 210 includes a protective box 211, which is assembled on the bottom inner wall of the forging box 110. A servo motor 212 is fixedly installed on the inner wall of the protective box 211. The servo motor 212 is fixedly connected to a transmission shaft 213. The top of the transmission shaft 213 passes through the top of the protective box 211 and is fixedly connected to a circular turntable 214 and a semicircular turntable 215. The top of the circular turntable 214 is eccentrically fixedly connected to a drive shaft 216.

[0027] Specifically, when the servo motor 212 drives the transmission shaft 213 to rotate, the transmission shaft 213 will drive the circular turntable 214 and the semicircular turntable 215 to rotate together, and the driving shaft 216 fixed on the circular turntable 214 will rotate around the transmission shaft 213 .

[0028] like Fig.10As shown, the intermittent component 230 includes a positioning shaft 231, the two ends of which are respectively fixed on the inner walls of the forging table 131 and the forging box 110, the outer ring rotating sleeve of the positioning shaft 231 is provided with a groove wheel 232 and an anti-stuck baffle 233, the groove wheel 232 is provided with a plurality of first grooves 232a adapted to the lower die 302, a second groove 232b is provided between every two first grooves 232a, the semicircular turntable 215 is adapted to the first groove 232a, and the drive shaft 216 is adapted to the second groove 232b.

[0029] Specifically, the first conveying wheel 132 conveys the lower die 302 to the first groove 232a through the first elastic guide plate 134. After that, every time the driving shaft 216 rotates one circle, the groove wheel 232 will also rotate a certain angle, which is the angle between the two second grooves 232b. After the semicircular turntable 215 partially enters the first groove 232a, even if the driving shaft 216 and the second groove 232b are separated from the groove wheel 232, it cannot continue to rotate, thereby driving the lower die 302 to move intermittently. When the lower die 302 moves to the bottom of the hydraulic equipment, it is forged by the upper die 301, and finally the lower die 302 is conveyed to the second conveying member 122 through the cooperation of the second conveying wheel 133 and the second elastic guide plate 135.

[0031] Specifically, each time the driving shaft 216 rotates one circle, it will drive the return frame 221 to move back and forth in a straight line once, and cooperate with the groove wheel 232, so that after each lower mold 302 is conveyed to the second conveying wheel 133, the return frame 221 will drive the pushing rod 222 to push the anti-stuck baffle 233 closer to the lower mold 302, so that the lower mold 302 will not be stuck in the first groove 232a, and finally the second conveying wheel 133 will convey it to the second conveying member 122. When the pushing rod 222 is away from the anti-stuck baffle 233, the anti-stuck baffle 233 will drive itself back to its original position through the force of the torsion spring, so that it will not affect the forging of the upper mold 301 and the lower mold 302.

[0032] Working principle: the first conveying member 121 conveys the lower die 302 to the interior of the forging box 110. When it reaches the opening of the forging table 131, the first conveying wheel 132 conveys the lower die 302 to the workstation of the intermittent component 230, starts the servo motor 212, drives the transmission shaft 213 to rotate, and the transmission shaft 213 drives the circular turntable 214 and the semicircular turntable 215 to rotate together. The driving shaft 216 fixed on the circular turntable 214 rotates around the transmission shaft 213. The first conveying wheel 132 conveys the lower die 302 to the first groove 232a through the first elastic guide plate 134. After that, every time the driving shaft 216 rotates one circle, the groove wheel 232 will also rotate a certain angle, and the angle is the angle between the two second grooves 232b. After the semicircular turntable 215 partially enters the first groove 232a, even if the driving shaft 216 and the second groove 232b are separated from the groove wheel 232, it will not The method continues to rotate, thereby driving the lower die 302 to move intermittently. After the lower die 302 moves to the bottom of the hydraulic equipment, it is forged through the upper die 301, and finally the lower die 302 is transported to the second conveying member 122 through the cooperation of the second conveying wheel 133 and the second elastic guide plate 135. The driving shaft 216 drives the return frame 221 to move back and forth once in a straight line every time it rotates one circle, and cooperates with the groove wheel 232 to make each lower die 302 After being transported to the second conveying wheel 133, the return frame 221 will drive the push rod 222 to push the anti-stuck baffle 233 to move closer to the lower die 302, so that the lower die 302 will not be stuck in the first groove 232a, and finally the second conveying wheel 133 is transported to the second conveying member 122. When the push rod 222 is away from the anti-stuck baffle 233, the anti-stuck baffle 233 will drive itself back to its original position through the force of the torsion spring, so that it will not affect the forging of the upper die 301 and the lower die 302.
