DETAILED DESCRIPTION

[0015] The following is combined with Figure 1-3 The embodiments of the present utility model are described in detail.

[0016] A forging device for a pulley comprises a frame 1, a support platform 2 is arranged in the middle position of the frame 1, a notch 7 is provided in the middle position of the support platform 2, a support block 5 is arranged in the notch 7, both ends of the support block 5 are connected with a rotating shaft 15, a rotating seat 16 is provided at the positions on the left and right sides of the support block 5 in the frame 1, the rotating shaft 15 is rotatably arranged in the rotating seat 16, a flip motor 14 is arranged in the frame 1, the motor shaft of the flip motor 14 is drivingly connected to one of the rotating shafts 15, limiting holes 8 are provided on the left and right sides of the support block 5, a hydraulic cylinder 2 9 is arranged in the frame 1, a limiting pin 10 is connected to the piston rod of the hydraulic cylinder 2 9, and the limiting pin 10 can be inserted into the limiting hole 8, a hydraulic cylinder 1 3 is arranged on the upper part of the frame 1, the lower end of the piston rod of the hydraulic cylinder 1 3 is connected with a die 4, and a conveying mechanism is arranged below the support platform 2.

[0017] The flip motor 14 drives the support block 5 to rotate and flip the die base 6 upward. The hydraulic cylinder 2 9 controls the extension of its piston rod to drive the limit pin 10 to insert into the limit hole 8, thereby completing the fixation of the position of the support block 5. The raw material is placed in the die base 6, and the hydraulic cylinder 1 3 controls the extension of its piston rod to drive the die 4 to descend into the die base 6, so that the raw material is die-cast in the die base 6.

[0018] After die casting is completed, the hydraulic cylinder 1 3 controls its piston rod to extend and retract, so that the limit pin 10 is disengaged from the limit hole 8, and the limit on the support block 5 is released. The flip motor 14 drives the support block 5 to rotate, flipping the die base 6 to the bottom, and the product in the die base 6 falls on the conveying mechanism below.

[0019] The conveying mechanism includes a bracket 17 arranged below the support platform 2, and rotating rollers 18 are rotatably arranged on both sides of the bracket 17, and a conveyor belt 19 is arranged between the two rotating rollers 18, and the conveyor belt 19 is made of metal. A driving motor 22 is arranged on the bracket 17, and the driving motor 22 drives and connects to a driving pulley 21, and a coaxial driven pulley 20 is arranged on one of the rotating rollers 18, and a transmission belt 23 is connected between the driven pulley 20 and the driving pulley 21. The driving pulley 21 is driven by the driving motor 22 to rotate, and the driving pulley 21 then drives the driven pulley 20 to rotate through the transmission belt 23, and the driven pulley 20 drives the coaxial rotating roller 18 to rotate, thereby driving the conveyor belt 19 to rotate. The conveyor belt 19 transports the products falling on it.

[0020] In order to prevent the product from falling out during the flipping of the die base 6, a mounting block 11 is provided on the upper part of the die base 6, and a hydraulic cylinder 3 12 is provided on the outer side of the mounting block 11, and a stopper 13 is connected to the piston rod of the hydraulic cylinder 3 12. Before the support block 5 starts to rotate, the hydraulic cylinder 3 12 controls its piston rod to extend, driving the stopper 13 to move inward, so that the stopper 13 reaches the top of the product in the die base 6. When the die base 6 flips, the stopper 13 blocks the product to prevent the product from falling out of the die base 6. After the die base 6 is driven by the support block 5 to reach the bottom, the hydraulic cylinder 3 12 controls its piston rod to contract again, driving the stopper 13 to move outward, and no longer blocks the product. At this time, the product can fall out of the die base 6.

[0021] A support plate 24 is provided inside the bracket 17, a buffer plate 25 is provided above the support plate 24, the buffer plate 25 is located below the rotating roller 18, the buffer plate 25 is provided below the support block 5, and a plurality of springs 26 are connected between the buffer plate 25 and the support plate 24. The buffer plate 25 supports the conveyor belt 19 above it to prevent the product from falling and damaging the conveyor belt 19. At the same time, the spring 26 plays a buffering role, further reducing the damage of the product to the conveyor belt 19.

[0022] Baffles 28 are installed on the front and rear sides of the bracket 17 through fixed arms 27. The baffles 28 are located above the conveyor belt 19. The distance between the left ends of the two baffles 28 is greater than the distance between the right ends, and the distance between the right ends of the two baffles 28 is slightly greater than the diameter of the product. The baffles 28 guide and limit the conveying of the products on the conveyor belt 19, and can prevent the products from falling off the conveyor belt 19. Due to the change in the distance between the two baffles 28, the products can be automatically arranged as the conveyor belt 19 moves, making the conveying of the products more orderly.

[0023] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
