Technical Field

[0001] The invention relates to aluminum alloy production equipment, in particular to a precision casting aluminum alloy wheel hub forging heating device. Background Art

[0002] like Figure 1 As shown, an aluminum alloy wheel hub blank comprises a blank body with a through hole in the middle.

[0003] At present, a Chinese patent with announcement number CN221087156U discloses a mesh belt continuous forging heating furnace, including a heating device and four connecting devices. The heating device includes a body, a transmission port, and four shells. The transmission port is located inside the body, and the heating device is arranged inside the body.

[0004] The above patent still has shortcomings. The feed port and the discharge port of the above patent are open. In order to ensure the temperature balance inside the heating furnace, a circulating fan is usually placed in the heating furnace. When the feed port is open, the hot air in the furnace will leak out, resulting in reduced heating efficiency and increased energy consumption of the heating furnace. The general solution is to partially close the feed port and the discharge port of the heating furnace through a door curtain, but the closing effect is poor, and lighter blanks are easily blocked by the door curtain, so it is not suitable for lighter products. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a precision cast aluminum alloy wheel hub forging heating device, which has the advantages of good sealing effect and adaptability.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a precision cast aluminum alloy wheel hub forging heating device, comprising a furnace body, a feed port and a discharge port are respectively arranged at the left and right ends of the furnace body, a conveyor belt assembly and a heating assembly are arranged in the furnace body, a circulating fan is arranged above the furnace body, a feeding shaft is arranged at the feed port and the discharge port, the feeding shaft is rotatably arranged in the furnace body, a motor for driving the feeding shaft to rotate is also arranged on the outside of the furnace body, a feeding trough is opened on the feeding shaft, the transmission belt assembly comprises a loading conveyor belt, a unloading conveyor belt and a heating conveyor belt, the heating conveyor belt is arranged in the middle of the loading conveyor belt and the unloading conveyor belt, a connecting seat is also arranged between the loading conveyor belt and the heating conveyor belt, a raw material fixing assembly is also arranged on the heating conveyor belt, and a unloading manipulator is also arranged at the side end of the unloading conveyor belt.

It has the advantages of better sealing effect and better adaptability. By setting a raw material fixing component, the circulating fan is prevented from blowing the blank body, and the raw material is clamped into the forging die by the unloading robot.

[0008] Preferably, the connecting seat is also provided with a pressing roller and a driving source for driving the pressing roller to rotate, the outer side of the pressing roller is wrapped with a rubber layer, and a through groove for the blank body to pass through is opened in the middle of the connecting seat, and the front end of the through groove is inclined.

[0009] Through the above technical means, by setting a pressing roller and a rubber layer, power is provided for the blank body entering the through groove, and by setting the front end of the through groove to be inclined, the blank body is prevented from being stuck at the front end of the connecting seat.

[0010] Preferably, the driving source 1 includes gear 1 arranged on the feeding shaft, gear 2 meshing with gear 1 and gear 3 arranged on the pressing roller. A feed trough is also provided on gear 1, and the feed trough causes gear 2 and gear 3 to rotate intermittently.

[0011] Through the above technical means, through the cooperation between gear one, gear two and gear three, the press roller is driven to rotate by motor one, and a feed groove is opened on gear one, so that gear two and gear three rotate intermittently, so that when the feed shaft pushes the blank body into the front end of the press roller, the press roller stops rotating, and when the feed groove on gear one passes through the rear gear two, the teeth of gear one are re-engaged with gear two. At this time, gear three drives the press roller to rotate, thereby completing the timed feeding.

[0014] Preferably, the raw material fixing assembly includes a support plate, a positioning rod and a driving source 2 for driving the positioning rod to move up and down. The support plate is arranged on a heating conveyor belt. A sliding hole is opened in the middle of the support plate. The positioning rod slides in cooperation with the sliding hole.

DETAILED DESCRIPTION

[0022] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0023] A precision cast aluminum alloy wheel hub forging heating device, comprising a furnace body 1, a feed port 2 and a discharge port 3 are respectively arranged at the left and right ends of the furnace body 1, a conveyor belt assembly 4 and a heating assembly 5 are arranged in the furnace body 1, the heating assembly 5 includes a resistance wire, a circulating fan 6 is arranged above the furnace body 1, a feed shaft 7 is arranged at the feed port 2 and the discharge port 3, the feed shaft 7 is rotatably arranged in the furnace body 1, a motor 1 is also arranged on the outside of the furnace body 1 to drive the feed shaft 7 to rotate, a feed trough 8 is opened on the feed shaft 7, and the transmission belt assembly includes a feeding conveyor belt 9. A feeding conveyor belt and a heating conveyor belt 11. The feeding conveyor belt 9 has the same structure as the feeding conveyor belt, and is composed of a guide roller, a belt, and a motor. The heating conveyor belt 11 is arranged in the middle of the feeding conveyor belt 9 and the feeding conveyor belt. A connecting seat 12 is also arranged between the feeding conveyor belt 9 and the heating conveyor belt 11. A raw material fixing component 13 is also arranged on the heating conveyor belt 11. A feeding robot 14 is also arranged at the side end of the feeding conveyor belt, and a casting machine for casting aluminum alloy wheels is also arranged at the other end of the feeding robot 14.

[0024] Therefore, when the feed chute 8 rotates to a downward direction, the blank body 90 can enter the furnace body 1 through the feed shaft 7, thereby reducing the furnace. When the feed chute 8 rotates to other positions, the distance between the feed shaft 7 and the loading conveyor belt 9 and the unloading conveyor belt is smaller, so that the equipment has the advantages of better sealing effect and better adaptability. By setting the raw material fixing component 13, the circulating fan 6 is prevented from blowing the blank body 90, and the raw material is clamped into the forging die through the unloading robot 14.

[0025] A pressure roller 35 and a driving source 1 for driving the pressure roller 35 to rotate are also provided on the connecting seat 12. The outer side of the pressure roller 35 is wrapped with a rubber layer. Arc grooves are provided on both sides of the connecting seat 12 to fit the shape of the belt. A through groove 15 is provided in the middle for the blank body 90 to pass through. The front end of the through groove 15 is inclined. The driving source 1 includes a gear 16 provided on the feed shaft 7, a gear 2 17 meshing with the gear 1 16, and a gear 3 18 provided on the pressure roller 35. The gear 2 17 is used to adjust the direction of the pressure roller 35 to be consistent with the feed shaft 7. A feed groove 8 is also provided on the gear 16. The feed groove 8 causes the gear 2 17 and the gear 3 18 to rotate intermittently.

[0026] By opening a feed groove 8 on gear one 16, gear two 17 and gear three 18 are made to rotate intermittently. When the feeding shaft 7 pushes the blank body 90 into the front end of the pressure roller 35, the pressure roller 35 stops rotating. When the feed groove 8 on gear one 16 passes through the rear gear two 17, the teeth of gear one 16 are re-engaged with gear two 17. At this time, gear three 18 drives the pressure roller 35 to rotate, thereby completing the timed feeding and making the movement of the blank body 90 compatible with the raw material fixing component 13.

[0027] A grinding roller 21 is also provided at the discharge port 3, and a gear four 19 is provided at the side end of the grinding roller 21. A gear five 20 is also provided at the side end of the gear four 19, and the gear five 20 is respectively meshed with the gear four 19 and the gear one 16. A grinder 22 is also provided at the side end of the unloading robot 14, and the surface of the blank body 90 is grinded by the grinding roller to remove the oxide scale generated on the upper surface of the blank body 90 due to heating. The unloading robot 14 clamps the blank body 90 through the inner expansion shaft. When the blank body 90 moves to the unloading conveyor belt, the blank body 90 is taken by the unloading robot 14 and moved to the grinder 22 to grind the lower surface and side of the blank body 90, thereby removing the oxide scale of the entire blank body 90, thereby solving the problem that it is difficult for the unloading robot 14 to turn over the blank body 90.

[0028] The raw material fixing assembly 13 includes a support plate 23, a positioning rod 24 and a driving source 25 for driving the positioning rod 24 to move up and down. The support plate 23 is arranged on the heating conveyor belt 11. A sliding hole 26 is opened in the middle of the support plate 23. The positioning rod 24 slides with the sliding hole 26. The driving source 25 drives the positioning rod 24 to be inserted into the through hole 91 of the blank body 90. The driving source 25 includes a guide plate 27 arranged in the furnace body 1. The left and right sides of the guide plate 27 are provided with inclined guide plates 28. A ball head slider 29 is arranged at the bottom of the positioning rod 24. When the ball head slider 29 slides on the guide plate 27, the sliding hole 26 protrudes from the top of the positioning rod 24, and a heating assembly 5 is arranged on the guide plate 27.

[0029] When the ball head slider 29 slides on the inclined guide plate 28, the positioning rod 24 gradually moves upward, thereby automatically completing the positioning when the heating conveyor belt 11 drives the blank body 90 to move, thereby preventing the lighter blank body 90 from moving due to the shaking of the circulating fan 6 and the equipment, thereby ensuring the transportation accuracy. When the heating conveyor belt 11 drives the blank body 90 to pass through the abrasive roller 21, the ball head slider 29 disengages from the guide plate 27. At this time, the positioning rod 24 directly unloads the material, so that the blank body 90 can be separated from the heating conveyor belt 11. The friction force is reduced by the ball head slider 29, thereby reducing the wear of the positioning rod 24 and increasing its service life. By arranging the heating component 5 on the guide plate 27, the lower end of the blank body 90 is heated.

[0030] The heating conveyor belt 11 includes a heating conduction roller 30 and a pair of heat-resistant conveyor belts 31 arranged on both sides. The heating conduction roller 30 is driven by a motor. Belt grooves 32 are arranged at both ends of the heating conduction roller 30. The two heat-resistant conveyor belts 31 are both arranged in the belt grooves 32. Connecting columns 34 are fixedly arranged on both sides of the support plate 23 and are respectively fixed to the two heat-resistant conveyor belts 31. The heat-resistant conveyor belts 31 are made of ceramic fiber rubber to ensure that the heat-resistant conveyor belts 31 will not melt in a high temperature environment. The support plate 23 and the two heat-resistant conveyor belts 31 are fixed by positioning columns, so that a cavity appears in the middle of the heat-resistant conveyor belt 31, so that the heating component 5 can better heat the blank body 90.

[0031] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
