Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to an emergency device for overheating of automobile parts during heat treatment. Background Art

[0002] During the production and processing of automobile parts, heat treatment processes are usually required to improve their mechanical and physical properties. However, during the heat treatment process, automobile parts may overheat due to excessively high heating temperatures. At this time, corresponding emergency measures need to be taken to quickly deal with the overheating of automobile parts. However, existing emergency measures usually involve taking the overheated automobile parts out of the heating equipment. During the taking-out process, some of the parts are taken out manually with the help of tools. Therefore, when the heating equipment is turned on during the taking-out process, hot air will gush out, causing the hot air to gush toward the workers and cause injuries. At the same time, after the overheated automobile parts are taken out, static annealing method will be used to place the automobile parts in a constant temperature environment for natural cooling. During the natural cooling, the parts will be placed in a constant temperature environment for natural cooling. The cooling process is slow. In order to speed up the cooling of the static annealing auto parts, the workers will spray water on the auto parts. In the process of spraying water, the water will produce hot water vapor after contacting the overheated auto parts. If the workers are close to the auto parts, the hot water vapor will scald the workers. At the same time, when spraying water on the overheated auto parts to cool them down, the uniformity of the spraying cannot be effectively controlled. If more water is sprayed, the temperature difference between the auto parts and the sprayed water will be too large, which will cause thermal shock to the auto parts and cause stress concentration inside the auto parts, thereby reducing the strength and durability of the auto parts, and even causing serious problems such as cracks or breakage, thereby shortening the service life of the auto parts. Summary of the invention

[0003] In view of this, and in response to the deficiencies of the prior art, the present invention provides an emergency device for heat treatment of overheating of automotive parts, so as to solve the problem that the prior art directly immerses the overheated automotive parts in coolant, causing stress concentration inside the automotive parts and reducing their strength and durability.

[0005] Preferably, the mounting plate is L-shaped as a whole, and the mounting plate is in contact with the inner wall of the heating furnace, and the two sides of the baffle are engaged with the inner wall of the storage frame, and both are porous structures.

[0010] Preferably, the cooling mechanism includes a water tank, which is fixedly connected to the outer wall of the top of the protective cover. No less than two sealing cylinders are symmetrically arranged on the side of the water tank close to the heating furnace. Piston rods are movably connected to the inner surfaces of the two sealing cylinders. A delivery pipe is commonly connected between the two sealing cylinders. A nozzle is arranged at one end of the delivery pipe away from the sealing cylinder and passes through the top of the protective cover.

[0011] Preferably, a one-way water inlet valve is provided between the sealing cylinder and the water storage tank, and a one-way water outlet valve is provided between the sealing cylinder and the delivery pipe.

[0012] Preferably, at least two limiting grooves are symmetrically opened on the top of the protective cover, at least two plastic clips are fixedly connected to the top of the mounting plate, and the two plastic clips are located inside the limiting grooves, and one end of the piston rod located outside the sealing cylinder is fixedly connected to a connecting rod, and the plastic clip is adapted to the connecting rod.

[0014] Compared with the prior art, the present invention provides an emergency device for overheating of automobile parts heat treatment, which has the following beneficial effects:

[0015] By engaging the processing rack with the heating furnace and driving the ball screw on the protective cover to rotate through an external motor, the storage frame is brought into contact with the storage rack, and then the automobile parts squeeze the baffle to cause it to rotate into the storage frame. At the same time, under the elastic action of the torsion spring, all the automobile parts can be shoveled into the storage frame, and then the external motor rotates in the opposite direction to take them out of the heating furnace, thereby all the overheated automobile parts can be taken out, thereby avoiding the situation where workers are injured by hot air when manually taking out the automobile parts with the help of tools. At the same time, taking out all the overheated automobile parts at one time can also ensure that the temperature between the automobile parts can be maintained, thereby ensuring the quality of subsequent processing or assembly.

[0016] Under the mutual cooperation of the synchronous wheel and the synchronous belt, the controllable pitch propeller on the protective cover is driven to rotate synchronously through the ball screw, so that air can be drawn from the external environment and blown continuously to the overheated auto parts, thereby dispersing the heat emitted by the auto parts themselves and the water vapor generated when the auto parts are subsequently cooled by the cooling mechanism. This can not only reduce the risk of workers being scalded by the heat emitted by the auto parts and the water vapor generated when the auto parts are subsequently cooled, but also improve the working environment of the operators and reduce the impact of high temperature on the operators, but also speed up the natural cooling efficiency of the overheated auto parts, thereby improving the processing efficiency of auto parts.

[0017] The mounting plate drives the plastic buckle on it to slide along the inside of the limit groove, so that the plastic buckle contacts the connecting rod, and under the limiting effect of the limit groove which changes from wide to narrow, the two are engaged with each other, thereby driving the piston rod to slide back and forth, and utilizing the principle of air pressure difference and the action of the one-way valve to spray a small amount of cooling water onto the outer surface of the overheated automotive part, thereby avoiding excessive temperature difference between the automotive part and the cooling water due to excessive amount of sprayed water, and effectively controlling the uniformity of the sprayed water, thereby achieving a relatively gentle cooling process, reducing the generation of thermal stress, and thus protecting the integrity and performance of the part.

[0018] The gear on the storage frame meshes with the rack on the protective cover, so that the storage frame can be turned over at a uniform speed during the process of moving and resetting to the processing rack, so that the automobile parts can be evenly sprayed with a small amount of cooling water, which can quickly and evenly absorb part of the heat on the surface of the automobile parts, and can effectively alleviate the overheating of the automobile parts, thereby realizing pre-cooling emergency treatment measures for the overheated automobile parts.

[0029] The present invention is further described in detail below based on the accompanying drawings and embodiments.

A storage rack 102 is provided in the heating furnace 1, and the storage rack 102 is L-shaped as a whole, and its transverse surface is inclined, which facilitates the rapid removal of the auto parts when overheating occurs; a processing rack 2 is provided on one side of the heating furnace 1 close to the furnace door 101, and the heating furnace 1 and the processing rack 2 are detachable, and the processing rack 2 is engaged in the hole of the heating furnace 1 by an elastic buckle. A protective cover 201 is fixedly connected to the top of the processing rack 2, and a mounting plate 203 is slidably connected to the top of the processing rack 2 through a groove. No less than two ball screws 202 are symmetrically fixedly connected to the protective cover 201, and the bottom of the mounting plate 203 is threadedly connected to the ball screw 202, wherein the mounting plate 203 is L-shaped as a whole, and the mounting plate 203 fits the inner wall of the heating furnace 1, which is used to ensure that the mounting plate 203 can extend into the interior of the heating furnace 1. Figure 3 and Figure 4As shown, the mounting plate 203 is fixedly connected to one side away from the heating furnace 1 with at least two access racks 3, and the two access racks 3 are arranged parallel to each other. The two access racks 3 are symmetrically rotatably connected with a rotating shaft 304, and a storage frame 301 is fixedly installed at one end of the rotating shaft 304 extending to the inner side of the access rack 3, and a baffle 302 is rotatably installed on the side of the storage frame 301 close to the heating furnace 1, and a torsion spring 303 is installed between the baffle 302 and the storage frame 301, and the two sides of the baffle 302 are engaged with the inner wall of the storage frame 301, and the baffle 302 is pushed by the storage rack 102 to rotate inside the storage frame 301, and the baffle 302 and the storage frame 301 are porous structures, which are used to improve the heat dissipation effect of overheated automobile parts, and the outer wall of the bottom of the storage frame 301 is flush with the top of the storage rack 102, which is used to ensure that the storage frame 301 can shovel the automobile parts on the storage rack 102 into its interior.

[0031] Please refer to Figures 1 to 4 As shown, a flip assembly for driving the storage frame 301 to rotate is provided on the protective cover 201, and the flip assembly includes a gear 305, which is fixedly mounted on the outer surface of the rotating shaft 304, and the gear 305 is located outside the picking rack 3. At least two racks 306 are fixedly connected to the inner wall of the protective cover 201, and the racks 306 are meshed with the gears 305.

[0032] Working process: When using the device, the staff pushes the processing rack 2 so that the processing rack 2 is engaged with the heating furnace 1, and then opens the furnace door 101, and then drives the ball screw 202 on the protective cover 201 to rotate through the external motor. At this time, the staff controls the propeller on the controllable pitch propeller 401 to rotate and change its inclination angle by pressing the control button set on the protective cover 201, so that when the ball screw 202 drives the mounting plate 203 to move toward the heating furnace 1, the controllable pitch propeller 401 can be controlled. The protective cover 201 of the propeller 401 is continuously blown, thereby effectively blowing the hot air gushing out of the heating furnace 1 to the position where the staff is standing. At this time, the mounting plate 203 on the ball screw 202 slides into the heating furnace 1. When the storage frame 301 on the mounting plate 203 contacts the storage rack 102, the gear 305 on the storage frame 301 is disengaged from the rack 306, and the bottom of the storage frame 301 on one side of the baffle 302 is in contact with the lower side of the storage rack 102. The storage rack 102 with an inclined top squeezes the storage frame 301 and rotates it along the rotating shaft 304, so that the end close to the heating furnace 1 tilts upward, and then the bottom of the storage frame 301 fits the inclined surface of the top of the storage rack 102, and the auto parts on the storage rack 102 are contacted with the baffle 302 and squeeze the baffle 302 to rotate inside the storage frame 301, and at the same time, the torsion spring 303 is squeezed to contract, and then the storage frame 301 with an inclined frame opening position is pushed All the auto parts thereon slide into the storage frame 301. When all the auto parts enter the storage frame 301, the auto parts no longer resist the baffle 302, so that the torsion spring 303 loses its restriction and returns to its original position, thereby driving the baffle 302 to close the storage frame 301, thereby preventing the auto parts in the storage frame 301 from sliding out of the storage frame 301, and facilitating the purpose of automatically taking out the overheated auto parts, and preventing the risk of being scalded by the hot air gushing out when the heating furnace 1 is opened during manual taking out. Subsequently, the external motor rotates in the opposite direction to drive the mounting plate 203 to move in the opposite direction through the ball screw 202, and the storage frame 301 carries the automobile parts and separates them from the heating furnace 1 and moves them to the processing rack 2, so that the overheated automobile parts can be quickly taken out of the heating furnace 1, thereby preventing the overheated automobile parts from being in the heating furnace 1 for a long time and affecting the performance of the automobile parts, thereby avoiding the problem that a large number of automobile parts cannot be taken out manually at one time, resulting in inconsistent temperatures of the automobile parts taken out one after another, causing some automobile parts to stay in the heating furnace 1 for a long time, and can ensure the consistency of temperature between automobile parts, thereby ensuring the quality of subsequent processing or assembly.During this process, the gear 305 on the storage frame 301 meshes with the rack 306 again, so that the storage frame 301 flips at a uniform speed while sliding with the mounting plate 203, so that the auto parts can be sprayed with a small amount of cooling water in all directions, and then part of the heat on the surface of the auto parts can be quickly and evenly absorbed, and the overheating of the auto parts can be effectively alleviated, so that pre-cooling emergency measures can be implemented for the overheated auto parts.

[0033] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 7 As shown, a protective mechanism for dispersing the heat of the auto parts itself is provided through a circular opening on the protective cover 201, and the protective mechanism includes a fixed cover 4, which is symmetrically arranged on both sides of the protective cover 201, and the protective cover 201 is placed on the outside of the fixed cover 4, and a controllable pitch propeller 401 is rotatably connected inside the fixed cover 4, and the controllable pitch propeller 401 is located inside the circular opening; in addition, no less than two ball screws 202 are rotatably connected to the protective cover 201, and a synchronous wheel 402 is fixedly connected to the ball screw 202 and the controllable pitch propeller 401, and the synchronous wheels 402 are connected through a synchronous belt 403, thereby the synchronous belt 403 can drive the controllable pitch propeller 401 to rotate during the movement of the driving mounting plate 203, and holes for inserting the ball screw 202 are opened twice at the bottom of the heating furnace 1.

[0034] Working process: when the operator pushes the processing rack 2 to take out the overheated auto parts, the operator is located at the fixed cover 4. Therefore, the protective mechanism can blow the hot air emitted by the auto parts themselves away from the operator when taking out the overheated auto parts. At the same time, the hot air gushing out when the furnace door 101 on the heating furnace 1 is opened can be blown away in the opposite direction, and the water vapor generated when the auto parts are cooled by the cooling mechanism can also be blown away in the direction away from the operator, thereby preventing the operator from being scalded, and also preventing the operator from being scalded due to improper operation when taking out the overheated auto parts at close range. The specific operation is as follows: when the mounting plate 203 is driven by the ball screw 202 to move onto the processing rack 2, the ball screw 202, under the mutual cooperation of the synchronous wheel 402 and the synchronous belt 403, the controllable pitch propeller 401 on the protective cover 201 also rotates synchronously, thereby being able to draw air from the external environment and Air is continuously blown toward the overheated auto parts, and when the ball screw 202 drives the mounting plate 203 to move in the opposite direction, causing the storage frame 301 to carry the auto parts and separate from the heating furnace 1 and move to the processing rack 2, the staff presses the control button to rotate the propeller on the controllable pitch propeller 401 to change its inclination angle. At this time, when the ball screw 202 drives the mounting plate 203 to move toward the processing rack 2, the protective cover 201 of the controllable pitch propeller 401 can also be continuously blown, thereby blowing away the hot air emitted by the auto parts themselves, and blowing away the hot air gushing out when the furnace door 101 on the heating furnace 1 is opened in the opposite direction, and the water vapor generated when the cooling mechanism cools the auto parts can also be blown away in a direction away from the operator, which can not only quickly disperse the hot air on the surface of the auto parts and accelerate the heat exchange rate between them and the surrounding environment, but also improve the working environment of the operators and reduce the impact of high temperature on the operators.

[0035] Example 3: Please refer to Figures 1 to 7As shown, a cooling mechanism for pre-cooling automobile parts is arranged on the top of the protective cover 201, and the cooling mechanism includes a water tank 5, which is fixedly connected to the outer wall of the top of the protective cover 201, and the side of the water tank 5 close to the heating furnace 1 is symmetrically connected to no less than two sealing cylinders 501, and the inner surfaces of the two sealing cylinders 501 are slidably connected to piston rods 502, and the two sealing cylinders 501 are commonly connected to a delivery pipe 504, and the delivery pipe 504 is T-shaped, and the middle part of the delivery pipe 504 extends to one end of the protective cover 201 and is fixedly connected to a nozzle 506, and The nozzle 506 is located above the interior of the storage frame 301; in addition, a one-way water inlet valve 505 is provided between the sealing cylinder 501 and the water storage tank 5, and a one-way water outlet valve 507 is provided between the sealing cylinder 501 and the delivery pipe 504, wherein water can only flow from the latter to the former between the sealing cylinder 501 and the water storage tank 5, and can only flow from the former to the latter between the sealing cylinder 501 and the delivery pipe 504, thereby ensuring that a small amount of cooling water is sprayed onto the outer surface of the automobile parts in the storage frame 301, so as to avoid excessive water spraying that causes damage to overheated automobile parts. At the same time, at least two limiting grooves 205 are symmetrically provided on the top of the protective cover 201, at least two plastic buckles 204 are fixedly connected to the top of the mounting plate 203, and the two plastic buckles 204 are located inside the limiting grooves 205, and one end of the piston rod 502 located outside the sealing cylinder 501 is fixedly connected with a connecting rod 503, and the connecting rod 503 is located on the movement trajectory of the plastic buckles 204; wherein, the limiting grooves 205 are a structure from wide to narrow as a whole, which is used for the connecting rod 503 to enter the plastic buckle 204, and the plastic buckle 204 is gradually tightened and fitted on the connecting rod 503 through the limiting grooves 205, thereby driving the piston rod 502 to slide, and the cross-section of the plastic buckle 204 is a cone-shaped, and the outer surface of the plastic buckle 204 fits with the limiting grooves 205, thereby limiting the opening size of the plastic buckle 204.

[0036] The cooling mechanism can pre-cool the overheated auto parts in a small amount by means of water mist, thereby effectively preventing the auto parts from being affected in strength and durability due to the temperature not being treated in time. The specific operation is as follows: when the mounting plate 203 drives the storage frame 301 to take out the overheated auto parts, the plastic buckle 204 on the mounting plate 203 slides along the inside of the limiting groove 205, causing the plastic buckle 204 to contact the connecting rod 503. When the plastic buckle 204 slides to a position from wide to narrow, the plastic buckle 204 is in contact with the connecting rod 503. When the limiting grooves 205 meet, the limiting grooves 205 squeeze the plastic buckle 204, causing its front end to shrink inward, and making the plastic buckle 204 engage with the outer surface of the connecting rod 503. Then, the connecting rod 503 slides toward the heating furnace 1 along with the mounting plate 203 and pulls the piston rod 502 to move in the same direction. At this time, the internal space of the sealing cylinder 501 increases and the air pressure decreases. By utilizing the principle of air pressure difference and the action of the one-way water inlet valve 505, the water inside the water storage tank 5 is forced to flow into the sealing cylinder 501. When the storage frame 301 on the mounting plate 203 carries the overheated automobile parts and moves to the processing rack 2, the plastic buckle 204 on the mounting plate 203 pulls the piston rod 502 on the connecting rod 503 to slide in the opposite direction. At this time, the internal space of the sealing cylinder 501 is reduced, thereby forcing the cooling water in the sealing cylinder 501 to flow through the delivery pipe 504 and spray from the inside of the nozzle 506 to the outer surface of the automobile parts in the storage frame 301, thereby being able to pre-cool the overheated automobile parts, thereby achieving a relatively gentle cooling process, reducing the generation of thermal stress, and protecting the integrity and performance of the parts.

[0037] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
