DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 7 As shown, the feeding device for heating the forging bar material comprises an intermediate frequency furnace 1, a feed plate 2 arranged at the feed end of the intermediate frequency furnace 1, a feed pusher 3 for pushing the bar material from the feed plate 2, and also comprises:

[0025] A conveyor belt mechanism 10 for conveying the bars to the feed plate 2;

[0026] An intermediate conveyor 20 for conveying the bars to the conveyor belt mechanism 10;

[0027] A material turner 30 for pouring the bar material into the intermediate conveyor 20;

[0028] The intermediate conveyor 20 is arranged vertically with the material turning machine 30, and the conveyor belt mechanism is arranged vertically with the intermediate conveyor 20;

[0029] The tipping machine 30 includes a frame 31, a tipping hopper 32, a rotating shaft 33, two sets of hydraulic lifters 34 for driving the tipping hopper 32 to flip along the rotating shaft 33, and a transition platform 35. The rotating shaft 33 is rotatably arranged on the frame 31, the tipping hopper 32 is connected to the rotating shaft 33, the hydraulic lifter 34 is arranged on the frame 31, and the hydraulic lifter 34 cooperates with the tipping hopper 32, the transition platform 35 is arranged on the frame 31, and the transition platform 35 cooperates with the feeding end of the intermediate conveyor 20.

[0030] Specifically, a V-shaped groove is provided on the feed plate 2 , and the V-shaped groove can prevent the bar material from rolling out of the feed plate 2 , making it easier for the feed pusher 3 to push the bar material.

[0031] Specifically, the discharge end of the medium frequency furnace 1 is also provided with a feeder 50 , a high and low temperature sorter 52 , a side push cylinder 60 , a high temperature rod detection device 61 , and a quick lifting device 62 .

[0032] Specifically, the hydraulic lifter 34 is a hydraulic cylinder.

[0033] Put the material frame filled with rods into the tipping hopper 32 of the tipping machine 30, start the rising button on the tipping machine 30, and the two sets of hydraulic lifters 34 work at the same time. The hydraulic lifters 34 lift the tipping hopper up. Since the tipping machine 30 is also provided with a hinge mechanism (not shown in the drawings), the tipping hopper 32 is lifted by the hydraulic lifter 34 and flipped along the rotating shaft 33, thereby pouring the rods onto the transition platform 35, and the rods then enter the intermediate conveyor 20 from the transition platform 35.

[0034] Arranging the intermediate conveyor 20 and the material tipping machine 30 vertically can shorten the straight-line length of the intermediate conveyor 20 and the material tipping machine 30, thereby reducing the area occupied by the intermediate conveyor 20 and the material tipping machine 30 in a straight line. Arranging the conveyor belt mechanism 10 and the intermediate conveyor 20 vertically can also shorten the straight-line length of the conveyor belt mechanism 10 and the intermediate conveyor 20, thereby reducing the area occupied by the conveyor belt mechanism 10 and the intermediate conveyor 20 in a straight line.

[0035] The material frame filled with rods is very heavy. In order to make the tipping hopper 32 rise more smoothly, the tipping machine 30 adopts two sets of hydraulic lifts 34, and the two sets of hydraulic lifts 34 work at the same time. Since the tipping machine 30 is higher than the intermediate conveyor 20, when the rods fall into the intermediate conveyor 20, due to the large drop, the rods are very likely to damage the intermediate conveyor 20. Therefore, in order to prevent the intermediate conveyor 20 from being damaged by the rods, a transition platform 35 is set on the frame 31 of the tipping machine 30. When the tipping machine 30 is loading, the rods fall from the tipping hopper 32 onto the transition platform 35, and then roll into the intermediate conveyor 20 from the transition platform 35. The transition platform 35 is used to shorten the drop between the intermediate conveyor 20 and the tipping machine 30, thereby protecting the intermediate conveyor 20. At the same time, the transition platform 35 can also reduce the noise when the rods fall.

[0036] The rods are conveyed to the conveyor belt mechanism 10 through the intermediate conveyor 20, and then conveyed to the feed plate 2 by the conveyor belt mechanism 10. The rods roll to the V-groove of the feed plate 2, and then the feed pusher 3 pushes the rods one by one into the medium frequency furnace 1 for heating. After heating, the rods are sent out from the discharge end of the medium frequency furnace 1, and then the quick lifting device 62 drags the heated rods to the high-temperature rod detection device 61 for temperature measurement. After measurement, the side push cylinder 60 pushes the rods to the feeding table 63, and the rods roll along the feeding table to the feeding plate 51, and then the feeder 50 pushes the rods into the high and low temperature separator 52. After sorting by the high and low temperature separator 52, the rods with a temperature in the range of 1150℃-1200℃ will be directly sent to the die forging hammer for processing, and the rods with a temperature higher than 1200℃ will be cooled, and the rods below 1150℃ will be heated.

[0037] The conveyor belt mechanism 10 includes a conveyor belt frame 11 and a conveyor belt 12 . The conveyor belt frame 11 is provided with an active transmission device 13 for driving the conveyor belt 12 to move.

[0038] Specifically, the active transmission device 13 includes a driving motor 13-1, a reduction box 13-2, a main transmission gear 13-3, and a sub-transmission gear 13-5. The reduction box 13-2 cooperates with the output end of the driving motor 13-1, the main transmission gear 13-3 is connected to the output end of the reduction box 13-2, the sub-transmission gear 13-5 cooperates with the gear on the conveyor belt frame 11 (not shown in the drawings), and the conveyor belt 12 is meshed with the gear on the conveyor belt frame 11. After the driving motor 13-1 is started, the reduction box 13-2 adjusts the speed of the driving motor 13-1, the reduction box 13-2 drives the main transmission gear 13-3 to rotate, the main transmission gear 13-3 drives the sub-transmission gear 13-5 to rotate through the chain 13-4, and the sub-transmission gear 13-5 drives the gear on the conveyor belt frame 11 to rotate, thereby driving the conveyor belt 12 to rotate.

[0039] The conveyor belt frame 11 is provided with a material detection switch 14, a material pressing device 15, a material blocking device 16, an incoming material detection device 17 and a conveyor belt pushing device 18 for pushing the rod material from the conveyor belt 12 to the feed plate 2. The material pressing device 15 is located downstream of the material detection switch 14, the material blocking device 16 is located downstream of the material pressing device 15, the conveyor belt pushing device 18 is located downstream of the material blocking device 16, and the incoming material detection device 17 is located downstream of the conveyor belt pushing device 18.

[0040] Specifically, Figure 2 and Figure 3As shown, after the bar A is sent from the intermediate conveyor 20 to the conveyor belt 12, the conveyor belt 12 gradually transports the bar A downstream. When there is no bar A on the conveyor belt 12, the material detection switch 14 will send an instruction to the controller, allowing the controller to control the intermediate conveyor 20 to continue to transport the bar A to the conveyor belt 12. When there is bar A on the conveyor belt 12, the material detection switch 14 will send an instruction to the controller, allowing the controller to control the intermediate conveyor 20 to stop transporting the bar A to the conveyor belt 12, so as to prevent the bar A from accumulating on the conveyor belt 12.

[0041] After the bar A contacts the incoming material detection device 17, the incoming material detection device 17 sends an instruction to the controller, and the controller controls the conveyor belt pushing device 18 to work. The conveyor belt pushing device 18 pushes the bar A into the V-groove of the feed plate 2. When pushing the bar A, the conveyor belt pushing device 18 can only push one bar at a time, and when pushing the bar A, the bar A upstream of the blocking device 16 will be blocked. When the conveyor belt pushing device 18 pushes a bar A, the blocking device 16 will lower a bar A. At the same time, the pressing device 15 will press on the bar A to prevent the bar A from moving to the downstream end on the conveyor belt 12. Only when the blocking device 16 lowers a bar A, the pressing device 15 will release the upstream bar A and allow the bar A to move downstream (that is, reach the position of the blocking device 16).

[0042] Specifically, the material blocking device 16 includes an oblique thrust cylinder 16-1, a first support 16-2, a second support 16-3, a material blocking shaft 16-4, and a material blocking plate 16-5. The oblique thrust cylinder 16-1 is fixed on the ground, the first support 16-2 and the second support 16-3 are respectively arranged on both sides of the conveyor belt frame 11, and the two ends of the material blocking shaft 16-4 are arranged on the first support 16-2 and the second support 16-3, and one end of the material blocking shaft 16-4 is connected to the piston rod of the oblique thrust cylinder 16-1, and the material blocking plate 16-5 is connected to the material blocking shaft 16-4.

[0043] When there is bar material A at the downstream end of the conveyor belt 12 (i.e., the conveyor belt pushing device 18), the oblique thrust cylinder 16-1 pushes the blocking shaft 16-4 to rotate on the first support 16-2 and the second support 16-3, so that the blocking plate 16-5 follows the blocking shaft 16-4 to flip, and the blocking plate 16-5 blocks the upstream bar material A. When there is no bar material A at the downstream end of the conveyor belt 12 (i.e., the conveyor belt pushing device 18), the oblique thrust cylinder 16-1 controls the piston rod to retract, and the blocking shaft 16-4 rotates on the first support 16-2 and the second support 16-3, so that the blocking plate 16-5 follows the blocking shaft 16-4 to flip, and the blocking plate 16-5 returns to the initial position and lowers the bar material A.

[0044] The incoming material detection device 17 includes a fixed seat 17-1, a stopper 17-2, a detection switch 17-3, and a fixing nut 17-4. The fixed seat 17-1 is fixed on the conveyor belt frame 11, the stopper 17-2 passes through the fixed seat 17-1, and the stopper 17-2 is sleeved on the detection switch 17-3, and the fixing nut 17-4 is threadedly matched with the stopper 17-2.

[0045] Specifically, the fixed seat 17-1 is fixed on the conveyor belt frame 11, and the fixing nut 17-4 locks the block 17-2 on the fixed seat 17-1. The block 17-2 is used to install the detection switch 17-3. At the same time, the block 17-2 can also protect the detection switch 17-3 from being hit by the rod A. When the rod A contacts the axial end face of the block 17-2, the detection switch 17-3 detects the rod A, and the detection switch 17-3 sends an induction signal to the controller, which controls the conveyor belt pushing device 18 to push the rod A onto the feed plate 2.
