Description

Technical Field

[0001] This invention belongs to the technical field of aluminum-silicon co-infiltration furnaces, specifically relating to a lifting-type vacuum aluminum-silicon co-infiltration furnace. Background Technology

[0002] Vacuum aluminum-silicon co-infiltration furnaces are specialized equipment for chemical heat treatment of metallic materials in a vacuum environment. The core principle involves reducing the furnace pressure to an extremely low level through vacuum extraction, followed by heating to a high temperature, and introducing an aluminum- and silicon-containing infiltration agent. Under the synergistic effect of vacuum and high temperature, the infiltration agent decomposes into active atoms. These atoms diffuse into the surface of the metal matrix, forming a composite infiltration layer containing aluminum and silicon. This process significantly improves the material's resistance to high-temperature oxidation, corrosion, and heat, making it particularly suitable for metal components in aerospace, energy equipment, and other fields that require long-term exposure to high temperatures or corrosive environments, such as turbine blades and combustion chambers, to extend their service life and enhance reliability.

[0003] Currently, the gripper structure of co-diffusion furnaces can only accommodate muffle pots of specific sizes. When production needs are adjusted or processes are upgraded to require the replacement of different models of muffle pots, the existing grippers lack an adjustable mechanism and cannot achieve size self-adaptation through mechanical deformation or intelligent control. The entire gripping assembly must be manually disassembled and replaced. This deficiency not only extends equipment downtime and reduces production efficiency but also increases spare parts inventory costs and operational complexity. Summary of the Invention

[0004] The purpose of this invention is to provide a lifting vacuum aluminum-silicon co-infiltration furnace to solve the problem mentioned in the background art that the existing grippers cannot be adjusted according to different models of muffle tanks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting vacuum aluminum-silicon co-infiltration furnace, comprising...

[0006] Organism;

[0007] The heating system is installed inside the machine body and has a gap between it and the bottom of the machine body; this facilitates the movement of the muffle can to the bottom of the heating system. During processing, a vacuum is drawn, and then the temperature is raised to a high temperature, while an aluminum and silicon-containing diffusion agent is introduced. Under the synergistic effect of vacuum and high temperature, the diffusion agent decomposes into active atoms, which diffuse into the surface of the metal substrate through diffusion, forming a composite diffusion layer containing aluminum and silicon.

[0008] A horizontal drive mechanism has one end extending into the interior of the heating system and the other end located outside the body of the machine. This horizontal drive mechanism passes directly below the heating system.

[0009] A lifting mechanism is installed on one side of the top of the machine body, and the other end of the lifting mechanism is on the same side as the horizontal drive mechanism; a gripper is installed on the lifting mechanism;

[0010] The gripper includes a hook frame, inside which is a vertically adjustable pole. A connecting arm is rotatably connected to the pole. A detachable claw is provided at the end of the connecting arm. An adjustment assembly is provided between the claw and the connecting arm. The adjustment assembly includes a connector and an elastic element.

[0011] The connector is fixed at one end to the end of the connecting arm, and the other end passes through the pawl; the elastic element is disposed between the connecting arm and the pawl.

[0012] Preferably, the connector includes at least two screws, one end of which is fixed to the end of the connecting arm, and the other end passes through the pawl. A nut is also optionally provided on the other end of the screw.

[0013] Preferably, the elastic element is an inner spring sleeved on the screw. The inner spring is located between the pawl and the connecting arm. When it is necessary to adjust the distance between the pawl and the connecting arm to meet the needs of different models of muffle cans, the nut can be rotated. At this time, under the rebound of the inner spring, the connecting arm and the pawl will be ejected in opposite directions, thereby realizing the adjustment.

[0014] Preferably, a mating piece is attached to the outside of the claw, which is connected through the screw. An external spring is also provided between the nut and the mating piece. The external spring allows for horizontal adjustment when the claw descends, preventing the opening distance of the claw from being less than the diameter of the top flange of the muffle tank. After the claw passes the flange of the muffle tank, the rebound of the external spring can achieve clamping and limiting. The inner side of the bottom of the claw is inclined from bottom to top.

[0015] Preferably, the lifting mechanism includes a linear slide rail installed on one side of the top of the machine body, and an electric hoist installed on the linear slide rail. The upright is installed at the end of the electric hoist. When the upright is stretched, it will drive the connecting arm to rotate downward, thereby clamping the muffle can.

[0016] Preferably, the horizontal drive mechanism includes a guide rail extending into the interior of the machine body at one end, and a slide table slidably disposed on the guide rail. The structure of the entire horizontal drive mechanism is similar to that of the linear slide rail and is an existing structure, so it will not be described in detail here. A vacuuming mechanism is provided on the top of the slide table, which is used to vacuum the placed muffle can.

[0017] Preferably, it also includes a muffle can, the bottom of which is mounted on a vacuum mechanism, and the top of which is held by the hook bracket.

[0018] Preferably, the interior of the machine body is also equipped with a liftable component. Specifically, the liftable component is driven to rise and fall by a mechanism inside the machine body, such as a linear slide rail. This is existing technology and will not be described in detail here. The liftable component is located on both sides of the bottom of the heating system. The heating system heats the muffle tank, while the vacuum mechanism on the horizontal drive mechanism performs vacuuming and pressure balancing operations on the muffle tank.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The adjustable components are designed to be tailored to the actual size of the muffle tank. Operators can easily switch the clamping range without replacing the entire set of clamps, significantly improving the equipment's versatility. The same co-infiltration furnace can accommodate muffle tanks of various sizes to meet the processing needs of different batches, reducing downtime caused by tank size mismatch. At the same time, the adjustable components have high overall strength and sufficient load-bearing capacity, enabling safe and stable lifting of the muffle tank and ensuring operational safety and reliability during production.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Body 100;

[0034] The heating system 200 is installed inside the machine body 100 and has a gap between it and the bottom of the machine body 100; this facilitates the movement of the muffle tank 500 to the bottom of the heating system 200. During processing, a vacuum is drawn through 301, followed by heating to a high temperature, and an aluminum and silicon-containing diffusion agent is introduced. Under the synergistic effect of vacuum and high temperature, the diffusion agent decomposes into active atoms, which diffuse into the surface of the metal substrate through diffusion, forming a composite diffusion layer containing aluminum and silicon.

[0035] The horizontal drive mechanism 300 extends through the interior of the heating system 200 at one end and is located outside the body 100 at the other end. The horizontal drive mechanism 300 passes directly below the heating system 200.

[0036] The lifting mechanism 400 is installed on one side of the top of the machine body 100, and the other end of the lifting mechanism 400 and the horizontal drive mechanism 300 are on the same side; a gripper is installed on the lifting mechanism 400.

[0037] The gripper includes a hook frame 401, inside which is a vertically lifting pole 402. A connecting arm 403 is rotatably connected to the pole 402. A separate gripper 404 is provided at the end of the connecting arm 403. An adjustment component is provided between the gripper 404 and the connecting arm 403. The adjustment component includes a connector and an elastic element.

[0038] One end of the connector is fixed to the end of the connecting arm 403, while the other end passes through the claw 404; the elastic element is disposed between the connecting arm 403 and the claw 404.

[0039] In this embodiment, preferably, the connector includes at least two screws 406, one end of which is fixed to the end of the connecting arm 403, and the other end passes through the claw 404. A nut is also optionally provided on the other end of the screw 406.

[0040] In this embodiment, preferably, the elastic element is an inner spring 407 sleeved on the screw 406. The inner spring 407 is located between the pawl 404 and the connecting arm 403. When it is necessary to adjust the distance between the pawl 404 and the connecting arm 403 to meet the needs of different models of muffle cans 500, the nut can be rotated. At this time, under the rebound of the inner spring 407, the connecting arm 403 and the pawl 404 will be ejected in opposite directions, thereby realizing the adjustment.

[0041] In this embodiment, preferably, a mating piece 405 is also attached to the outside of the claw 404. The mating piece 405 is connected through the screw 406. An outer spring 408 is also provided between the nut and the mating piece 405. With the setting of the outer spring 408, the horizontal adjustment can be made when the claw 404 descends, so as to avoid the opening distance of the claw 404 being less than the diameter of the top flange of the muffle tank 500. When the claw 404 passes the flange of the muffle tank 500, the clamping limit can also be achieved by the rebound of the outer spring 408. The inner side of the bottom of the claw 404 is inclined from bottom to top.

[0042] In this embodiment, preferably, the lifting mechanism 400 includes a linear slide rail installed on one side of the top of the machine body 100, and an electric hoist installed on the linear slide rail. The upright 402 is installed at the end of the electric hoist. When the upright 402 is stretched, it will drive the connecting arm 403 to rotate downward, thereby achieving the clamping of the muffle tank 500.

[0043] In this embodiment, preferably, the horizontal drive mechanism 300 includes a guide rail extending into the interior of the body 100 at one end, and a slide table slidably disposed on the guide rail. The structure of the entire horizontal drive mechanism 300 is similar to that of the linear slide rail and is an existing structure, so it will not be described in detail here. A vacuuming mechanism 301 is provided on the top of the slide table. The vacuuming mechanism 301 is used to perform vacuuming on the placed muffle can 500.

[0044] In this embodiment, preferably, a muffle can 500 is also included. The bottom of the muffle can 500 is mounted on the vacuum mechanism 301, and the top of the muffle can 500 is held by a hook bracket 401.

[0045] In this embodiment, preferably, the interior of the body 100 is also provided with a liftable member 101. Specifically, the liftable member 101 is driven to rise and fall by a mechanism inside the body 100, such as a linear slide rail. This is existing technology and will not be described in detail here. The liftable member 101 is located on both sides of the bottom of the heating system 200. The heating system 200 heats the muffle tank 500, while the vacuum mechanism 301 on the horizontal drive mechanism 300 performs vacuuming and pressure balancing operations on the muffle tank 500.

[0046] Although embodiments of the invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
