Description

Technical Field

[0001] This invention belongs to the field of heat treatment technology for automotive door lock components, and more specifically, it relates to a heat treatment device for automotive door lock components and its usage method. Background Technology

[0002] Automotive door lock components require quenching during production, primarily due to their functional requirements. Door lock parts, such as the latch and shift fork, are subject to frequent mechanical impacts and friction over long periods, making them prone to wear or deformation. Quenching, through rapid cooling, forms a high-hardness martensitic structure on the surface of the steel, significantly improving wear resistance and fatigue strength. Simultaneously, proper control of the quenching process can reduce internal stress, prevent embrittlement, and ensure the stability and durability of the components under complex operating conditions. This process is a crucial step in ensuring the safety and reliability of door locks, directly impacting vehicle performance.

[0003] Currently, the following problems still exist in the quenching process of automotive door lock parts: 1. Automotive door lock parts cannot rotate automatically after contact with quenching liquid, resulting in the automotive door lock parts not being able to contact quenching liquid in different positions; 2. There is a lack of effective safety distance between the workers and the quenching equipment, which makes it easy for workers to be accidentally injured when the quenching equipment is working; 3. The quenched automotive door lock parts contain excess quenching liquid, and it is impossible to help remove the excess liquid from the surface of the quenched automotive door lock parts.

[0014] In another aspect, this disclosure provides a method of using a heat treatment apparatus for automotive door lock components, comprising the following steps:

[0016] 2) Place the car door lock parts to be quenched into the parts processing box, and then start the servo motor through the control panel to make the output shaft of the servo motor rotate 90 degrees.

[0017] 3) Wait for the car door lock parts to complete the quenching process in the quenching liquid;

[0018] 4) Start the servo motor through the control panel to make the output shaft of the servo motor rotate 90 degrees again, and then take the quenched car door lock parts out of the parts processing box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the control panel controls the servo motor to work, the circular drive shaft and two rectangular protrusions drive the accessory processing frame to rotate, causing the car door lock accessory to rotate in the circular liquid reservoir, thus enabling the car door lock accessory to contact the quenching liquid at different locations; when the circular drive shaft and two rectangular protrusions drive the accessory processing frame to rotate 90 degrees, the accessory processing frame drives the car door lock accessory into the quenching liquid; when the circular drive shaft and two rectangular protrusions drive the accessory processing frame to rotate 90 degrees again, the accessory processing frame drives the car door lock accessory out of the quenching liquid.

[0021] 2. When the positioning pin is inserted into the two positioning holes and the rectangular flip plate at the top, the rectangular flip plate is in a folded storage state, which helps to reduce the space occupied. When the positioning pin is inserted into the two positioning holes and the rectangular flip plate at the front, the rectangular flip plate is in an open state. At this time, there is a certain safe distance between the control panel and the circular liquid storage shell support, which improves the safety performance.

[0022] 3. In this invention, when the parts processing frame moves downward, the intake and exhaust rings move downward under their own weight and the tension of a return spring; when the parts processing frame moves upward, the intake and exhaust rings move upward under the action of the parts processing frame and the two circular support rods b; when the intake and exhaust rings move upward under the action of the parts processing frame and the two circular support rods b, the gas in the annular mounting cover is discharged through a ring of inclined air outlets, which helps to remove excess liquid from the surface of the quenched automotive door lock parts; when the intake and exhaust rings move downward under their own weight and the tension of a return spring, external gas enters the annular mounting cover through a ring of inclined air outlets.

[0023] 4. In this invention, when the intake and exhaust rings move upward under the action of the accessory processing frame and the two circular support rods b, the gas in the annular mounting cover does not initially exit from the inclined air outlet, but instead moves to the two auxiliary booster pipes. When the rectangular control hole contacts the inclined air outlet, the gas in the annular mounting cover and the two auxiliary booster pipes exits from the inclined air outlet. The rectangular control hole serves two purposes: firstly, when the quenched automotive door lock accessory has not been removed from the quenching liquid, the inclined air outlet does not emit air; secondly, when the quenched automotive door lock accessory is removed from the quenching liquid, the outlet pressure increases under the action of the two auxiliary booster plates, improving the removal effect of liquid from the surface of the automotive door lock accessory.

At this time, there is a certain safe distance between the control panel 203 and the support of the circular liquid storage shell 101, which enhances the safety performance.

[0048] In this embodiment of the disclosure, such as Figure 4 , Figure 5 , Figure 7 and Figure 9As shown, the liquid removal component 300 includes: an annular mounting cover 301, an inclined air outlet 302, and an inlet / outlet ring 303; the annular mounting cover 301 is fixedly mounted on the top of the U-shaped mounting frame 103, and arc-shaped slots 3011 are provided on the left and right sides of the annular mounting cover 301; the inclined air outlet 302 is provided in a ring, and the ring of inclined air outlets 302 is fixedly mounted on the inner wall of the annular mounting cover 301; the inlet / outlet ring 303 is slidably mounted inside the annular mounting cover 301; the liquid removal component 300 also includes: a circular support rod b304, a one-way valve 305, and a rectangular sealing sleeve 306; there are two circular support rods b304, and the two circular support rods b304 are fixedly mounted on the bottom of the inlet / outlet ring 303, and the bottom of the two circular support rods b304 contacts the accessory handling frame 106; there are two one-way valves 305, and the two one-way valves 305 are fixedly mounted on the inlet / outlet ring 303; the rectangular sealing sleeve 306 is provided in a ring.

[0049] Its specific function is as follows: Since the intake and exhaust ring 303 is slidably installed inside the annular mounting cover 301, and two circular support rods b304 are fixedly installed at the bottom of the intake and exhaust ring 303, with the bottoms of the two circular support rods b304 contacting the accessory processing frame 106, when the accessory processing frame 106 moves downward, the intake and exhaust ring 303 moves downward under its own weight and the tension of a return spring 309; when the accessory processing frame 106 moves upward, the intake and exhaust ring 303 moves upward under the action of the accessory processing frame 106 and the two circular support rods b304. The air intake and exhaust rings 303 move upward under the action of the accessory processing frame 106 and the two circular support rods b304. The gas in the annular mounting cover 301 is discharged through the inclined air intake and exhaust rings 302, which helps to remove excess liquid from the surface of the quenched automotive door lock accessories. When the air intake and exhaust rings 303 move downward under their own weight and the tension of the return spring 309, the external gas enters the annular mounting cover 301 through the inclined air intake and exhaust rings 302.

[0050] In this embodiment of the disclosure, such as Figure 1 and Figure 10 As shown, the auxiliary booster component 400 includes: an auxiliary booster pipe 401, a rectangular mounting plate 402, and a circular mounting shaft 403; the auxiliary booster pipe 401 is fixedly mounted on the annular mounting cover 301; the rectangular mounting plate 402 is fixedly mounted on the auxiliary booster pipe 401; the circular mounting shafts 403 are arranged in a row, and the row of circular mounting shafts 403 is slidably mounted on the rectangular mounting plate 402; the auxiliary booster component 400 also includes: an auxiliary booster plate 404 and a return spring 405; the auxiliary booster plate 404 is slidably mounted inside the auxiliary booster pipe 401, and the auxiliary booster plate 404 is also fixedly connected to the row of circular mounting shafts 403; the return springs 405 are arranged in a row, and the row of return springs 405 is sleeved on the outside of the row of circular mounting shafts 403, and the row of return springs 405 is located between the rectangular mounting plate 402 and the auxiliary booster plate 404;

When the intake and exhaust ring 303 moves upward under the action of the accessory processing frame 106 and the two circular support rods b304, the gas in the annular mounting cover 301 does not first exit from the inclined air outlet 302, causing the gas in the annular mounting cover 301 to move to the two auxiliary pressurization pipes 401; and because a rectangular control rod 307 has a rectangular control... The rectangular control hole 3071 is designed so that when it contacts the inclined air outlet 302, the gas in the annular mounting cover 301 and the two auxiliary booster pipes 401 is discharged from the inclined air outlet 302. The rectangular control hole 3071 serves two purposes: firstly, when the quenched car door lock parts are not removed from the quenching liquid, the inclined air outlet 302 does not discharge air; secondly, when the quenched car door lock parts are removed from the quenching liquid, the air pressure of the inclined air outlet 302 increases under the action of the two auxiliary booster plates 404, thereby improving the removal effect of liquid on the surface of the car door lock parts.

[0052] Furthermore, because the two one-way valves 305 are fixedly installed on the intake and exhaust rings 303, external gas can enter the annular mounting cover 301 through a ring of inclined air outlets 302 and the two one-way valves 305; and because a row of return springs 405 are sleeved on the outside of a row of circular mounting shafts 403, and the row of return springs 405 are located between the rectangular mounting plate 402 and the auxiliary booster plate 404, they push the gas in the two auxiliary booster pipes 401, so that the gas in the annular mounting cover 301 and the two auxiliary booster pipes 401 can be discharged quickly.

[0053] This invention provides a method for using a heat treatment device for automotive door lock components, comprising the following steps:

[0054] 1) Secure the circular liquid storage shell 101 with bolts, then pull out the positioning pin 204, then rotate the rectangular flip plate 202 ninety degrees, and then insert the positioning pin 204 into the two positioning holes 2011 and the rectangular flip plate 202 on the front side.

When 104 is working, the circular drive shaft 105 and the two rectangular protrusions 1051 drive the parts processing frame 106 to rotate, causing the car door lock parts to rotate within the circular liquid reservoir 101, thus enabling the car door lock parts to contact the quenching liquid at different locations; when the circular drive shaft 105 and the two rectangular protrusions 1051 drive the parts processing frame 106 to rotate 90 degrees, the parts processing frame 106 drives the car door lock parts into the quenching liquid; when the parts processing frame 106 moves downward, the intake and exhaust rings 303 move downward under their own weight and the tension of a return spring 309; when the intake and exhaust rings 303 move downward under their own weight and the tension of a return spring 309... Under the tension of the return spring 309, the external gas moves downward, and enters the annular mounting cover 301 through a tilted air outlet 302 and two one-way valves 305; wait for the car door lock parts to complete quenching in the quenching liquid; start the servo motor 104 through the control panel 203, so that the output shaft of the servo motor 104 rotates 90 degrees again; when the circular drive shaft 105 and the two rectangular protrusions 1051 drive the parts processing frame 106 to rotate 90 degrees again, the parts processing frame 106 moves the car door lock parts out of the quenching liquid; when the parts processing frame 106 moves upward, the intake and exhaust rings 303 are in the parts processing frame 101 Under the action of 06 and two circular support rods b304, the intake and exhaust rings 303 move upwards. When the intake and exhaust rings 303 move upwards under the action of the parts processing frame 106 and the two circular support rods b304, the gas in the annular mounting cover 301 does not first exit from the inclined air outlet 302, but moves to the two auxiliary booster pipes 401. When the rectangular control hole 3071 contacts the inclined air outlet 302, the gas in the annular mounting cover 301 and the two auxiliary booster pipes 401 exits from the inclined air outlet 302. Then, the quenched car door lock parts are taken out from the parts processing frame 106.
