Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts manufacturing and processing, specifically to a heat treatment device for a noise-reducing multi-stage buffer automotive steering tie rod. Background Technology

[0002] As a key component of the automotive steering mechanism, the steering tie rod significantly impacts vehicle handling stability, operational safety, and tire lifespan. During vehicle operation, the tie rod must bear steering forces and provide support, transmitting tensile and compressive loads. However, existing heat treatment processes for steering tie rods present numerous problems. Firstly, traditional heat treatment equipment is complex to operate, making it difficult to process large batches of tie rods, resulting in low efficiency. Secondly, some heat treatment methods, when increasing hardness, easily induce surface quenching cracks, leading to product scrap or breakage during use, causing economic losses for users. Furthermore, due to equipment and process defects, the heat treatment process for steering tie rods cannot effectively address the vibration and noise issues caused by road impacts and vibrations transmitted to the steering wheel through the tie rod. The poor damping effect of existing steering tie rods further exacerbates this problem. Therefore, developing a noise-reducing, multi-stage damping heat treatment device for automotive steering tie rods that can solve the above problems is urgently needed.

[0003] CN201220013509.6 discloses a heat treatment device, relating to the field of materials mechanics. It includes a heat treatment device body, which internally houses a heating system, a cooling system, and a quenching tank. An explosion-proof device is installed on the top of the front chamber of the heat treatment device body. It can induce acicular ferrite and retained austenite structures in the intermediate-temperature transformation zone of ductile iron, resulting in engineering materials with advantages such as high strength, high toughness, high impact toughness, good vibration absorption, good wear resistance, high bending fatigue and contact fatigue strength, light weight, energy saving, environmental protection, and low cost. However, it has shortcomings. During use, when feeding and transferring materials, the opening of the sealed door causes heat dissipation, leading to energy loss. Utility Model Content

[0004] The purpose of this invention is to provide a noise-reducing multi-stage buffer automotive steering tie rod heat treatment equipment, which solves the problem that when the device is in use, during material feeding and transfer, the opening of its sealed door causes internal heat dissipation, resulting in internal energy consumption.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a heat treatment device for noise reduction multi-stage buffer automotive steering tie rod, including a furnace body assembly. A flip door assembly is installed on the front side of the furnace body assembly, and a smoke exhaust assembly is fixedly installed on the top side of one side of the furnace body assembly. A convenient delivery window assembly is fixedly installed in the middle of the flip door assembly. The convenient delivery window assembly includes a limiting slot buckle, which is fixedly installed above the delivery window and on the outer wall of the flip-up sealing door. At the same time, a lifting limiting plate is installed inside the limiting slot buckle. The lifting limiting plate is slidably installed on the outside of the main window panel by adjusting the limiting bolt. The bottom of the main window panel is rotatably installed at the bottom of the delivery window by a limiting hinge.

[0006] Furthermore, the furnace body assembly includes a main furnace, with a handle fixedly installed on the top of the main furnace and a support frame fixedly installed at both ends of the bottom of the main furnace.

[0007] Furthermore, the main furnace has an internal insulation cavity, and a heating element is fixedly installed at the bottom of the insulation cavity.

[0008] Furthermore, the flip-top door assembly includes a flip-top sealing door, one side of which is rotatably mounted on the outer wall of the front side of the main furnace via a rotating hinge, and a limit buckle is fixedly installed on the outer wall of the other end of the flip-top sealing door. The limit buckle is limited and installed inside the locking fastener, and the locking fastener is fixedly installed on the outer wall of the other side of the main furnace.

[0009] Furthermore, a feeding window is provided in the middle of the flip-top sealing door.

[0010] Furthermore, the smoke exhaust assembly includes an installation pipe that runs through and is installed on the top side of the main furnace. A high-speed rotating drum is installed inside the installation pipe, and a smoke pump is fixedly installed inside the high-speed rotating drum. An exhaust pipe is fixedly installed at the outer end of the smoke pump.

[0011] This utility model has the following beneficial effects: (1) The heat treatment equipment for noise reduction multi-stage buffer car steering tie rod of this utility model has a convenient delivery window component installed in the middle of the front sealed door of the device. When using this device, the convenient delivery window component can provide convenient support for material delivery, so that the entire sealed door does not need to be opened, which would cause the internal temperature to be dispersed. (2) The heat treatment equipment for noise reduction multi-stage buffer car steering tie rod of this utility model has a smoke exhaust component installed on the device. When the device is heated inside, a certain amount of smoke may be generated. At this time, the smoke exhaust component can be used to exhaust the smoke and avoid the accumulated smoke from affecting the internal materials.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0016] Please see Figures 1-4As shown, this utility model is a heat treatment device for a noise reduction multi-stage buffer automotive steering tie rod, including a furnace body assembly 1, a flip door assembly 2 installed on the front side of the furnace body assembly 1, and a smoke exhaust assembly 4 fixedly installed on the top of one side of the furnace body assembly 1, and a convenient delivery window assembly 3 fixedly installed in the middle of the flip door assembly 2. The convenient delivery window assembly 3 includes a limiting slot buckle 301, which is fixedly installed above the delivery window 2011 and on the outer wall of the flip-up sealing door 201. A lifting limiting plate 302 is installed inside the limiting slot buckle 301. The lifting limiting plate 302 is slidably installed on the outside of the main window panel 304 via an adjusting limiting bolt 303. The bottom of the main window panel 304 is rotatably installed at the bottom of the delivery window 2011 via a limiting hinge 305. Small items are delivered through the convenient delivery window assembly 3. Adjusting the limiting bolt 303 allows the lifting limiting plate 302 to slide to a suitable position within the limiting slot buckle 301, facilitating the opening of the main window panel 304.

[0017] By installing a convenient delivery window component 3 in the middle of the front sealed door of the device, the convenient delivery window component 3 can provide convenient support for material delivery when using the device, so that the entire sealed door does not need to be opened, thus avoiding the dispersion of internal temperature.

[0018] The furnace body assembly 1 includes a main furnace 101, with a handle 102 fixedly installed on the top of the main furnace 101 and a support frame 103 fixedly installed at both ends of the bottom of the main furnace 101.

[0019] The main furnace 101 has an insulation cavity 1011 inside, and a heating element 1012 is fixedly installed at the bottom inside the insulation cavity 1011.

[0020] The flip-top door assembly 2 includes a flip-top sealing door 201. One side of the flip-top sealing door 201 is rotatably mounted on the outer wall of the front side of the main furnace 101 via a rotating hinge 202, and a limit buckle 203 is fixedly installed on the outer wall of the other end of the flip-top sealing door 201. The limit buckle 203 is limited and installed inside the locking fastener 204, and the locking fastener 204 is fixedly installed on the outer wall of the other side of the main furnace 101.

[0021] The flip-top sealing door 201 has a feeding window 2011 in the middle. By rotating the hinge 202, the flip-top sealing door 201 can be rotated around the front outer wall of the main furnace 101 to open. The car steering rod can be placed into the insulation cavity 1011 of the main furnace 101. If only small auxiliary items need to be delivered, there is no need to open the flip-top sealing door 201. The main window plate 304 can be rotated directly by the limiting hinge 305 to open the feeding window 2011 of the convenient delivery window assembly 3. After delivery, the main window plate 304 is closed, and the lifting limiting plate 302 is fixed by adjusting the limiting bolt 303 to ensure the window is sealed. The flip-top sealing door 201 is rotated back to its original position so that the limiting buckle 203 is engaged in the locking fastener 204, thereby closing and fixing the flip-top sealing door 201.

[0022] The smoke exhaust assembly 4 includes an installation pipe 401, which runs through and is installed on the top of one side of the main furnace 101. A high-speed rotating drum 402 is installed inside the installation pipe 401. A smoke pump 403 is fixedly installed inside the high-speed rotating drum 402. An exhaust pipe 404 is fixedly installed at the outer end of the smoke pump 403. The smoke exhaust assembly 4 uses the smoke pump 403 to generate suction to discharge the smoke and exhaust gas generated during the heat treatment process through the installation pipe 401 and the exhaust pipe 404, thus keeping the working environment clean.

[0023] This noise-reducing, multi-stage buffer automotive steering tie rod heat treatment equipment generates heat through the heating element 1012 within the furnace body assembly 1, creating a stable heat treatment environment within the insulation chamber 1011 for heat treatment of the automotive steering tie rod. The flip-door assembly 2 allows for the opening and closing of the furnace body, facilitating the placement and removal of workpieces; the convenient delivery window assembly 3 allows for the rapid delivery of small items through the opening and closing of the main window panel 304 without opening the flip-door sealing door 201; the smoke exhaust assembly 4 utilizes the smoke pump 403 to generate suction, discharging the smoke and exhaust gases generated during the heat treatment process through the installation pipe 401 and exhaust pipe 404, maintaining a clean working environment. During the workflow, it is checked whether each component of the equipment is installed correctly, including confirming that the support frame 103 of the furnace body assembly 1 firmly supports the main furnace 101, and that the rotating hinge 202 of the flip-door assembly 2 functions normally. The tilting sealing door 201 rotates around the front outer wall of the main furnace 101, ensuring that the locking fastener 204 and the limit buckle 203 are properly engaged, guaranteeing the equipment is in an operational state. If small items need to be delivered through the convenient delivery window assembly 3, adjust the limit bolt 303 to allow the lifting limit plate 302 to slide into the appropriate position within the limit groove buckle 301, facilitating the opening of the main window panel 304. The tilting sealing door 201 is then opened by rotating the hinge 202 around the front outer wall of the main furnace 101, allowing the car steering lever to be inserted into the insulation cavity 1011 of the main furnace 101. If only small auxiliary items need to be delivered, it is not necessary to open the tilting sealing door 201. The main window panel 304 is rotated directly via the limiting hinge 305 to open the feeding window 2011 of the convenient delivery window assembly 3. After delivery, the main window panel 304 is closed, and the lifting limiting plate 302 is fixed by adjusting the limiting bolt 303 to ensure the window is sealed. The flip-top sealing door 201 is rotated back to its original position, so that the limiting buckle 203 is engaged in the locking fastener 204, thereby closing and fixing the flip-top sealing door 201 and ensuring the insulation cavity 1011 is sealed. The heating element 1012 is activated, and heat is generated in the insulation cavity 1011 to heat the car steering tie rod. The insulation cavity 1011 can... To reduce heat loss and maintain a stable heat treatment temperature, the smoke pump 403 is turned on. The smoke pump 403 works in the high-speed rotating drum 402 to generate suction, which draws in the smoke and exhaust gas generated in the heat insulation chamber 1011 during the heat treatment process through the installation pipe 401 and then discharges it outside the equipment through the exhaust pipe 404. After the heat treatment is completed, the heating element 1012 and the smoke pump 403 are turned off, and the flip-top sealing door 201 is opened. The flip-top sealing door 201 is rotated around the front outer wall of the main furnace 101 by rotating the hinge 202, and the treated car steering rod is taken out from the heat insulation chamber 1011, thus completing the entire heat treatment process.
