Description

Technical Field

[0001] This utility model relates to the field of axle processing technology, specifically a non-magnetic high-nitrogen and high-manganese processing device for electric vehicle axle production. Background Technology

[0002] The axle of an electric vehicle is a core transmission component connecting the wheels and the suspension system, undertaking functions such as power transmission, load support, and steering control. Its core design must meet the requirements of high torque, lightweight, and durability. It is usually made of hollow alloy steel or aluminum alloy, manufactured through precision forging or liquid forming processes, and undergoes heat treatment to improve its strength.

[0003] Currently, most electric vehicle axles on the market are made of stainless steel containing a high proportion of nitrogen and manganese. To further enhance the mechanical strength and durability of the axles, they are usually hardened. During the hardening process, operators use hooks to remove the axles, heated to a high temperature, from the hardening furnace, and then quickly immerse them in a specific hardening liquid for rapid cooling. However, during this transfer from the hardening furnace to the hardening liquid, nitrogen on the axle surface may escape due to the high temperature, resulting in a nitrogen deficiency on the axle surface, known as nitrogen depletion. This surface nitrogen deficiency directly affects the axle's performance, reducing its key indicators such as strength and corrosion resistance. Utility Model Content

[0004] The purpose of this invention is to provide a non-magnetic high-nitrogen and high-manganese processing device for the production of electric vehicle axles, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-magnetic high-nitrogen and high-manganese processing device for electric vehicle axle production, comprising a quenching tank, a protective shell fixedly installed at the upper end of the quenching tank, a feed inlet at one end of the protective shell, a discharge outlet at the other end of the protective shell, a nitrogen inlet at the upper end of the protective shell, a transport mechanism inside the protective shell, the transport mechanism comprising a movable slide groove formed on the inner wall of the protective shell, a movable shaft slidably installed on the movable slide groove, a steel cable fixedly installed on the movable shaft, a hook fixedly installed at the lower end of the steel cable, and a gate assembly at the discharge outlet.

[0006] Preferably, the transport mechanism further includes an electric slide fixedly installed on the top of the protective housing, a slide block slidably installed on the electric slide, a guide rod fixedly installed on the slide block and slidably installed on the movable shaft, and a clamping sleeve fixedly installed at the upper end of the steel cable.

[0007] Preferably, a movable hole is provided at the middle position of the movable shaft, and the guide rod is movably installed on the movable shaft through the movable hole.

[0008] Preferably, the steel cable is fixedly installed on the movable shaft by a clamp, the two ends of the movable shaft are movably installed on the protective housing by movable grooves, and the guide rod is movably installed inside the protective housing by a sliding block.

[0009] Preferably, the gate assembly includes a front gate and a rear gate movably installed within a protective housing. Racks are fixedly installed on both sides of the front and rear gates. Positioning grooves are provided on both sides of the front and rear gates. A drive shaft is rotatably installed between the front and rear gates. A motor is connected to one end of the drive shaft. Transmission shafts are rotatably installed on both sides of the drive shaft. A clutch and a brake are provided on the transmission shaft. A gear is fixedly installed at the end of the transmission shaft.

[0010] Preferably, both the drive shaft and the transmission shaft are provided with helical gears, and the helical gears on the drive shaft and the transmission shaft mesh together.

[0011] Preferably, the gear is rotatably mounted on one side of the rack via a transmission shaft, and the gear meshes with the rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the high-temperature axle is lifted, the electric slide can be activated. Activation of the electric slide will drive the guide rod on the slide block to move forward, thereby pushing the movable shaft forward and ultimately moving the high-temperature axle forward. When the movable shaft reaches above the quenching tank, it will slide down the movable slide, immersing the high-temperature axle in the quenching liquid within the tank, thus completing the quenching process of the axle. Furthermore, during the transportation of the axle, nitrogen gas is injected into the protective shell through the nitrogen inlet to prevent nitrogen depletion from occurring on the axle surface due to nitrogen escaping.

[0014] 2. The quenched axle in this application is discharged through the outlet. Before discharge, the axle needs to be moved between the front and rear brakes. When the axle is positioned in this area, the rear brake is raised, followed by the front brake. After the front brake has lowered, the quenched axle can be discharged. This method effectively reduces nitrogen leakage inside the protective housing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a non-magnetic high-nitrogen and high-manganese processing device for electric vehicle axle production. It includes a quenching tank 1, a protective shell 2 fixedly installed on the upper end of the quenching tank 1, a feed inlet 3 at one end of the protective shell 2, a discharge outlet 5 at the other end of the protective shell 2, a nitrogen inlet 4 at the upper end of the protective shell 2, a transport mechanism 6 inside the protective shell 2, and a gate assembly 7 at the discharge outlet 5. The transport mechanism 6 can transport the high-temperature axle into the quenching tank 1 for quenching, and during the quenching process, nitrogen can be introduced into the protective shell 2 through the nitrogen inlet 4 to prevent nitrogen from escaping from the axle and causing nitrogen deficiency on the surface.

[0023] like Figure 2 and Figure 3 As shown, the transport mechanism 6 includes a movable slide 601 opened on the inner wall of the protective housing 2. A movable shaft 603 is slidably installed on the movable slide 601. A steel cable 606 is fixedly installed on the movable shaft 603. A hook 608 is fixedly installed at the lower end of the steel cable 606. A movable hole is opened in the middle of the movable shaft 603. A guide rod 607 is movably installed on the movable shaft 603 through the movable hole. The steel cable 606 is fixedly installed on the movable shaft 603 through a clamp 604. Both ends of the movable shaft 603 are movably installed on the protective housing 2 through the movable slide 601. The guide rod 607 is movably installed inside the protective housing 2 through a slide block 605.

[0024] Specifically, after the high-temperature axle is lifted, the electric slide 602 can be activated. Once activated, the slide block 605 will move, pushing the guide rod 607 forward. As the guide rod 607 moves forward, it further pushes the movable shaft 603 forward, thereby moving the high-temperature axle below it forward as well. When the movable shaft 603 reaches the top of the quenching tank 1, it slides down the movable slide 601, allowing the high-temperature axle to be immersed in the quenching liquid within the quenching tank 1, thus completing the quenching process. Furthermore, during the axle's transport, nitrogen gas can be introduced into the protective housing 2 through the nitrogen inlet 4. This is to prevent nitrogen from escaping from the axle and avoid nitrogen deficiency on the axle surface.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, the gate assembly 7 includes a front gate 701 and a rear gate 703 movably installed within the protective housing 2. Racks 708 are fixedly installed on both sides of the front gate 701 and the rear gate 703. Positioning grooves 702 are provided on both sides of the front gate 701 and the rear gate 703. A drive shaft 704 is rotatably installed between the front gate 701 and the rear gate 703. A motor 707 is connected to one end of the drive shaft 704. Transmission shafts 706 are rotatably installed on both sides of the drive shaft 704. A clutch 709 and a brake 710 are provided on the transmission shaft 706. A gear 705 is fixedly installed at the end of the transmission shaft 706. Helical gears are provided on both the drive shaft 704 and the transmission shaft 706, and the helical gears on the drive shaft 704 and the transmission shaft 706 mesh together.

[0026] Specifically, after the motor 707 is started, it begins to drive the drive shaft 704 to rotate. As the drive shaft 704 rotates, the transmission shaft 706 also rotates. The rotation of the transmission shaft 706 further drives the rotation of the gear 705. Once the gear 705 begins to rotate, it interacts with the rack 708, causing the rack 708 to move up and down. The up and down movement of the rack 708, in turn, drives the front brake 701 and the rear brake 703 to move up and down accordingly. Simultaneously, the brake 710 has the function of limiting the rotation of the transmission shaft 706, locking the front brake 701 or the rear brake 703 in a specific position. By precisely controlling the engagement and disengagement of each clutch 709, the raising and lowering operation of the front brake 701 or the rear brake 703 can be achieved, thus achieving precise control.

[0027] Working principle: When in use, the feed port 3 on the protective shell 2 is aligned with the outlet of the quenching furnace. When the high-temperature axle is discharged through the outlet of the quenching furnace, the high-temperature axle can be lifted by the hook 608. After the high-temperature axle is lifted, the electric slide table 602 can be started. After the electric slide table 602 is started, the slide block 605 will drive the guide rod 607 to move forward. After the guide rod 607 moves forward, it will drive the movable shaft 603 to move forward, thereby driving the high-temperature axle below the movable shaft 603 to move forward. When the movable shaft 603 moves to the top of the quenching tank 1, it will slide down along the movable slide 601, so that the high-temperature axle is immersed in the quenching liquid in the quenching tank 1, completing the quenching process of the axle. During the transportation of the axle, nitrogen can be introduced into the protective shell 2 through the nitrogen inlet 4 to prevent the nitrogen element of the axle from escaping and causing nitrogen depletion on the surface. After the axle is quenched, it can be discharged through the discharge port 5. Before the axle is discharged, it needs to be moved between the front gate 701 and the rear gate 703. After the axle is moved between the front gate 701 and the rear gate 703, the rear gate 703 can be raised. After the rear gate 703 is raised, the front gate 701 can be lowered. After the front gate 701 is lowered, the quenched axle can be discharged. Discharging the axle in the above manner can reduce the leakage of nitrogen gas inside the protective shell 2.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
