[0015] An automatic tempering process for an automobile shaft rod, the specific operation steps of the process are:

[0016] Step 1: Place the automobile shaft on the upper end surface of the loading plate, and the two loading plates rotate to complete the loading work;

[0017] Step 2: The two short rotating discs and the two long rotating discs rotate together to flip and transport the automobile shaft;

[0024] 2. When the automobile axle passes through the T-shaped blow hood, the automobile axle is cooled by the blow nozzle at the lower end of the T-shaped blow hood, and the T-shaped blow hood is in a left-right swinging state during use, so that the entire automobile axle can be blown by the cooling wind, ensuring the overall cooling effect of the automobile axle, avoiding the automobile axle can only perform local heat dissipation, affecting the tempering effect of the automobile axle.

[0025] 3. The operator places the automobile axles to be tempered on the upper end surface of the loading plate in turn. Since the loading plate is set at an angle, each automobile axle tends to move toward the upper material tray under the action of gravity. Then, during the rotation of the loading tray, the lowest automobile axle will be caught by the V-shaped grooves on the two loading trays. Then, the loading tray rotates toward the short rotating disk, thereby flipping the automobile axles on the loading tray and transporting them to the two short rotating disks. The loading is automatically completed with convenient operation. In addition, with the cooperation of the small gear disk and the large gear disk, the rotation speed of the loading tray is slowed down to avoid excessive loading, so that there is a certain interval between each automobile axle to avoid affecting the subsequent heating and cooling.

DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0033] Reference Figure 1-Figure 5 An automatic tempering device for an automobile axle comprises a tempering furnace 1, a plurality of short rotating shafts 2 are symmetrically arranged on the inner wall of the tempering furnace 1, a short rotating disk 3 is fixedly sleeved at the end of each short rotating shaft 2, a plurality of long rotating shafts 4 are symmetrically arranged on the inner wall of the tempering furnace 1, a long rotating disk 5 is fixedly sleeved at the end of each long rotating shaft 4, the short rotating shafts 2 and the long rotating shafts 4 are arranged at intervals, and a cooling component is arranged on the tempering furnace 1.

[0034] When in use, after the automobile axle to be tempered is moved to the two short rotating disks 3, the V-shaped grooves on the two short rotating disks 3 limit the automobile axle to prevent the automobile axle from shaking, and then the multiple short rotating shafts 2 and the multiple long rotating shafts 4 rotate clockwise together, thereby driving the short rotating disks 3 and the long rotating disks 5 to rotate. The automobile axle is flipped and transported from the two short rotating disks 3 to the two long rotating disks 5 in turn, and then flipped and transported from the two long rotating disks 5 to the next pair of short rotating disks 3, and so on and so forth until it passes through the exit of the tempering furnace 1. During the process of being flipped and transported, the automobile axle is continuously turned over, so that all sides of the automobile axle are heated evenly, the heating speed is fast, and it is easy to use.

[0035] A plurality of side flame-spraying tubes 6 are symmetrically fixed on the inner wall of the tempering furnace 1, and a plurality of bottom flame-spraying tubes 7 are symmetrically fixed on the inner surface of the tempering furnace 1. The upper end surface of the automobile axle rod is heated horizontally by the plurality of side flame-spraying tubes 6, and the lower end surface of the automobile axle rod is heated vertically by the plurality of bottom flame-spraying tubes 7, so that the automobile axle rod is heated faster.

[0036] Mounting covers 8 are fixed on both sides of the tempering furnace 1. Each short rotating shaft 2 and long rotating shaft 4 rotates through the mounting cover 8. A chain group for driving the short rotating shaft 2 and the long rotating shaft 4 to rotate is arranged in the mounting cover 8. A power motor 9 and a reduction motor 10 for driving the chain group to rotate are fixed on both sides of the tempering furnace 1.

[0037] The power motor 9 is set to rotate slowly, and cooperates with the reduction motor 10, so that the chain groups between each short rotating shaft 2 and the long rotating shaft 4 can rotate slowly, thereby driving the long rotating disk 5 and the short rotating disk 3 to rotate slowly together, and the automobile shaft rod is flipped and transported.

[0038] The cooling assembly includes an upper through slot 11 provided on the top of the tempering furnace 1, a T-shaped blowing hood 12 is rotatably provided on the inner wall of the upper through slot 11, a plurality of blowing nozzles are provided on the lower end surface of the T-shaped blowing hood 12, a ventilation slot 13 used in conjunction with the T-shaped blowing hood 12 is provided on the tempering furnace 1, and the upper end surface of the T-shaped blowing hood 12 is connected to an external cooling bellows through a ventilation pipe.

[0039] When the automobile axle passes through the T-shaped blow hood 12, the automobile axle is cooled by the blow nozzle at the lower end of the T-shaped blow hood 12, and the T-shaped blow hood 12 is in a left-right swinging state during use, so that the entire automobile axle can be blown by the cooling wind, ensuring the overall cooling effect of the automobile axle, avoiding the automobile axle only being able to dissipate heat locally, affecting the tempering effect of the automobile axle.

[0040] Grooved connecting plates 14 are fixed on both sides of the T-shaped blowing hood 12, and push rods 15 are hinged on the inner wall of the groove connecting plate 14. The push rods 15 movably penetrate the side walls of the tempering furnace 1. Rotating wheels 16 are rotatably provided on both sides of the tempering furnace 1, and arc-shaped abutment blocks 17 are fixed on the outer side walls of the rotating wheels 16. The end of each push rod 15 is inclined, and one end of each rotating wheel 16 is fixedly sleeved with a pulley 18, and a belt body 19 is transmission-connected between the pulley 18 and the power motor 9.

[0041] When the power motor 9 drives the reduction motor 10 to rotate, it will also drive the rotating wheel 16 to rotate. When the rotating wheel 16 rotates, it drives the arc-shaped resistance block 17 to rotate. When the arc-shaped resistance block 17 rotates, it will resist the end of the push rod 15, so that the push rod 15 moves toward the inside of the tempering furnace 1, thereby pushing the T-shaped blowing hood 12 to one side. When the arc-shaped resistance block 17 is away from the push rod 15, the arc-shaped resistance block 17 no longer applies force to the push rod 15. Under the action of gravity, the T-shaped blowing hood 12 moves in opposite directions. The two arc-shaped resistance blocks 17 are 180° apart, so that the arc-shaped resistance blocks 17 on both sides can drive the T-shaped blowing hood 12 to shake left and right when pushing their respective push rods 15, thereby completing the corresponding cooling operation, which is easy to use.

[0042] Two mounting seats 20 are symmetrically fixed on one side of the tempering furnace 1, and a loading rod 21 is rotatably penetrated on each mounting seat 20, and a loading plate 22 is fixedly sleeved on one end of each loading rod 21, and a large gear plate 23 is fixedly sleeved on the other end of each loading rod 21. The large gear plate 23 rotates and penetrates into the mounting cover 8, and a small gear plate is fixedly sleeved on the outer wall of the adjacent short rotating shaft 2, and the small gear plate is meshed and connected with the large gear plate 23. A loading plate 24 is obliquely arranged on one side of the tempering furnace 1, and side baffles are fixed on both sides of the loading plate 24, and a plurality of support rods 25 are fixed on the bottom of the loading plate 24.

[0043] The operator places the automobile axles to be tempered on the upper end surface of the loading plate 24 in turn. Since the loading plate 24 is inclined, each automobile axle tends to move toward the upper loading tray 22 under the action of gravity. Then, during the rotation of the loading tray 22, the lowest automobile axle will be caught by the V-shaped grooves on the two loading trays 22. Then, the loading tray 22 rotates toward the short rotating disk 3, thereby flipping the automobile axles on the loading tray 22 and conveying them to the two short rotating disks 3. The loading is automatically completed with convenient operation. In addition, with the cooperation of the small gear disk and the large gear disk 23, the rotation speed of the loading tray 22 is slowed down to avoid excessive loading, so that there is a certain interval between each automobile axle to avoid affecting the subsequent heating and cooling.

[0044] An automatic tempering process for an automobile shaft rod, the specific operation steps of the process are:

[0045] Step 1: Place the automobile shaft on the upper end surface of the loading plate 24, and the two loading trays 22 rotate to complete the loading work;

[0046] Step 2: The two short rotating disks 3 and the two long rotating disks 5 rotate together to flip and transport the automobile shaft;

[0047] Step 3, the T-shaped blowing hood 12 swings left and right to cool the automobile shaft.

[0048] In step 1, during the rotation of the loading disk 22 , the automobile shaft on the loading plate 24 is flipped and transported to two adjacent short rotating disks 3 .

[0049] In step 2, the automobile axle rod is flipped and transported from the two short rotating disks 3 to the two long rotating disks 5 in turn, and then flipped and transported from the two long rotating disks 5 to the next pair of short rotating disks 3, and so on, until it passes through the exit of the tempering furnace 1.

[0050] In step three, when the two arc-shaped abutment blocks 17 push their respective push rods 15, they can drive the T-shaped blowing hood 12 to swing left and right, thereby completing the corresponding cooling operation.

[0051] When the present invention is in use, the operator places the automobile axles to be tempered on the upper end surface of the loading plate 24 in sequence. Since the loading plate 24 is inclined, each automobile axle tends to move toward the upper material tray 22 under the action of gravity. Then, during the rotation of the loading plate 22, the automobile axle at the bottom will be caught by the V-shaped grooves on the two loading plates 22. Then, the loading plate 22 rotates toward the direction close to the short rotating plate 3, thereby flipping the automobile axle on the loading plate 22 and conveying it to the two short rotating plates 3. The loading is automatically completed, and the operation is convenient. In addition, with the cooperation of the small gear plate and the large gear plate 23, the rotation speed of the loading plate 22 is slowed down to avoid over-fast loading, so that there is a certain interval between each automobile axle to avoid affecting the subsequent heating and cooling.

[0052] After the automobile axle to be tempered moves to the two short rotating disks 3, the V-shaped grooves on the two short rotating disks 3 limit the automobile axle to prevent the automobile axle from shaking, and then the multiple short rotating shafts 2 and the multiple long rotating shafts 4 rotate clockwise together, thereby driving the short rotating disks 3 and the long rotating disks 5 to rotate, and the automobile axle is flipped and transported from the two short rotating disks 3 to the two long rotating disks 5 in turn, and then flipped and transported from the two long rotating disks 5 to the next pair of short rotating disks 3, and so on and so forth, until it passes through the exit of the tempering furnace 1. The automobile axle is constantly turned over during the flipping and transportation process, so that each surface of the automobile axle is heated evenly, the heating speed is fast, and it is easy to use;

[0053] When the automobile axle passes through the T-shaped blow hood 12, the automobile axle is cooled by the blow nozzle at the lower end of the T-shaped blow hood 12, and the T-shaped blow hood 12 is in a left-right swinging state during use, so that the entire automobile axle can be blown by the cooling wind, ensuring the overall cooling effect of the automobile axle, avoiding the automobile axle only being able to dissipate heat locally, affecting the tempering effect of the automobile axle.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
