Description

Technical Field

[0001] The present invention relates to the technical field of tool processing, and particularly relates to a tool heat treatment device and a processing method thereof. Background Art

[0002] A tool is a commonly used tool in daily life and industrial production. Usually, after forging a metal into shape, it is then prepared through heat treatment. During the heat treatment of the tool, when the tool heated at a high temperature is transported to a cooling chamber for cooling, the existing processes mainly rely on two mainstream methods - direct water quenching method and high-speed water flow flushing method. Compared with simple immersion water quenching, high-speed water flow flushing stands out with its more uniform and controllable cooling characteristics and becomes the preferred solution for tool manufacturers pursuing high-quality tools.

[0003] However, when the high-temperature tool contacts cold water instantaneously, a composite stain composed of oxidation products and mineral precipitates will inevitably form on its surface, commonly known as oxidation scale and water scale. The existence of these stubborn attachments hinders the full dissipation of the residual heat inside the tool, thereby affecting the final physical properties and durability of the tool material. In actual production, manual cleaning is generally adopted. The operator needs to use professional tools, such as wire brushes or scrapers, to remove the dirt on the surface of the tool one by one. Especially in a large-scale production environment, the tools are often fixed on a special tool rack in a dense array and undergo heating and cooling together. In this way, the cleaning difficulty of a single tool increases exponentially because not only the inconvenience caused by the close arrangement among individuals needs to be overcome, but also the unified progress of the whole batch of tools needs to be considered to prevent individual lagging cleaning links from slowing down the rhythm of the entire production line. Based on this, the present invention purposefully provides a tool heat treatment device and a processing method thereof that can synchronously clean the dirt generated on the surface when cooling a high-temperature tool and ensure the full release of the internal heat of the high-temperature tool. Summary of the Invention

[0004] The purpose of the present invention is to provide a tool heat treatment device and a processing method thereof for the deficiencies of the existing technology, so as to solve the technical problem that the inefficiency of manual descaling and the labor intensity restrict the tool heat treatment efficiency when cooling a high-temperature tool.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A tool heat treatment device includes:

[0007] A box body is divided into a heating chamber and a cooling chamber by a retractable first baffle. In the heating chamber, heating components are fixedly installed symmetrically up and down. In the cooling chamber, a high-speed water flow nozzle is slidably installed. The high-speed water flow nozzle is driven by a first output source to move. A drain pipe is opened on the bottom plate of the cooling chamber. A sliding frame is slidably installed in the box body. The sliding frame is driven by a third output source to move. A plurality of clamping seats are arranged on the sliding frame at equal intervals. A tool body is clamped and fixed on each clamping seat. When the first baffle contracts, the heating chamber and the cooling chamber communicate with each other.

[0008] A moving seat is slidably installed in the cooling chamber and is driven by a second output source to move. A plurality of brackets are fixedly installed on the moving seat at equal intervals. A cleaning brush and two cleaning combs are rotatably installed on each bracket. The cleaning brush is driven by a first synchronization component to rotate. When the second output source drives the moving seat to reciprocate under the tool body, both sides of each tool body are in contact with the bristles of the two cleaning brushes respectively. The two cleaning combs are arranged symmetrically with respect to the cleaning brush, and the comb teeth directions of the two cleaning combs are opposite. The cleaning combs are driven by a second synchronization component to rotate. When the cleaning combs rotate to be in contact with the bristles of the cleaning brush, the comb teeth of the cleaning combs and the bristles of the cleaning brush are arranged in an alternating pattern.

[0009] As a further scheme of the present invention: The clamping seat is rotatably installed on the sliding frame and is driven by an adjusting component to rotate. When the tool body is in the heating chamber, the adjusting component drives the clamping seat to rotate until the tool body is in a vertical state. When the tool body is in the cooling chamber and the high-speed water flow nozzle cools the tool body, the adjusting component drives the clamping seat to rotate until the tool body is in a horizontal state. When the cleaning brush cleans the tool body, the adjusting component drives the clamping seat to rotate until the tool body is in a vertical state.

[0010] As a further scheme of the present invention: The adjusting component includes a rack plate, a gear and an electric cylinder. The number of gears is the same as the number of clamping seats. The gears are fixedly installed on the clamping seat rotating shafts and are coaxially arranged with them. The rack plate is slidably installed in the sliding frame and meshes with the gears. The electric cylinder is fixedly installed in the sliding frame, and its movable end is fixedly connected to the rack plate.

[0011] As a further scheme of the present invention: The first synchronization component includes a first synchronous belt and a first driving source. The rotating shafts of adjacent two cleaning brushes are connected by the first synchronous belt in a transmission manner. One cleaning brush is driven by the first driving source to rotate.

[0012] As a further solution of the present invention: the second synchronous component includes a second synchronous belt, a driving wheel, a driven wheel and a third synchronous belt. The rotating shafts of the two cleaning combs located on the bracket are connected by the second synchronous belt transmission. One cleaning comb is driven to rotate by the second driving source. The driving wheel is fixedly installed on the rotating shaft of one cleaning comb, and the two are coaxially arranged. The driven wheel is fixedly installed on the rotating shaft of the other cleaning comb, and the two are coaxially arranged. The driving wheel and the driven wheel on two adjacent brackets are connected by the third synchronous belt transmission, and multiple third synchronous belts are parallel to each other.

[0013] As a further solution of the present invention: an air blowing port is provided in the cooling chamber, the air blowing port is connected to the cold air device, and is located below the high-speed water flow nozzle. When the sliding frame is located in the cooling chamber, the air blowing port faces the tool body.

[0014] As a further solution of the present invention: an air suction port is arranged on the top plate of the cooling chamber, and the air suction port is connected to the exhaust equipment.

[0015] A processing method for a tool heat treatment device, the method is applied to a tool heat treatment device as described above, the method comprising the following steps:

[0016] Step S1: First, a plurality of tool bodies are clamped and fixed in sequence by a sliding frame, a first baffle is retracted, a driving source drives the sliding frame to move into a heating chamber, the first baffle is extended, and then the tool bodies are heated at high temperature by a heating assembly;

[0017] Step S2: after the first baffle is retracted and the driving source drives the sliding frame to move from the heating chamber to the cooling chamber, the first baffle is extended, and then the high-speed water flow nozzle is driven to reciprocate through the first output source, and a high-speed water flow is sprayed to cool the tool body;

[0018] Step S3: When oxide scale is formed on the surface of the tool body, the first synchronization component drives the cleaning brush to rotate, and then the second output source drives the moving seat to move so that the cleaning brush contacts the tool body. At this time, two adjacent cleaning brushes can clean both sides of one tool body;

[0019] Step S4: When too much dirt accumulates on the cleaning brush, the cleaning comb is driven by the second synchronization component to rotate until it contacts the cleaning brush. At this time, the cleaning brush is cleaned by the cleaning comb during the process of rotating from one side of the tool body to the other side of the tool body;

[0020] Step S: When the tool body is completely cooled down, the moving seat is reset, and then the tool bodies are taken out one by one.

[0021] Beneficial effects of the present invention:

[0022] 1. In the present invention, the processing efficiency is ensured by a plurality of tool bodies arranged at equal intervals. The arrangement of a plurality of cleaning brushes on the moving seat ensures that both sides of each tool body can be in close contact with the bristles of two rotating cleaning brushes simultaneously, so that the dirt on both sides of each tool body can be removed at the same time, avoiding the problem of low efficiency in manually cleaning both sides of each tool body one by one. And when the cleaning comb rotates to make its comb teeth stagger with the bristles of the cleaning brush in space, when the cleaning brush rotates from the surface of one tool body to the surface of another tool body, it will pass through the cleaning comb. In this way, the comb teeth of the cleaning comb can effectively scrape and remove the debris retained in the bristles of the cleaning brush, directly eliminating the process of manually cleaning the bristles and ensuring the continuous cleaning state of the bristles;

[0023] 2. In the present invention, by rotating the clamping seat, the attitude of the tool body can be changed in real time according to the processing process of the tool body. Especially when cooling with high-speed water flow, it can ensure a stable switch between the vertical state and the horizontal state of the tool body. When it is in the horizontal state, it ensures that the high-speed water flow ejected by the high-speed water flow nozzle can fully cover the front surface of the tool body, greatly expanding the contact area of direct cooling, thereby accelerating the transfer and dissipation of heat. And after cooling, switching back to the vertical state can carry out the cleaning work of oxidation scale and water scale through the cleaning brush;

[0024] 3. In the present invention, the two cleaning combs on one bracket will rotate towards the middle at the same time, and the rotation of the cleaning comb will drive the driving wheel to rotate. Through the transmission of the third synchronous belt, it will drive the cleaning combs on the adjacent brackets to rotate. In this way, the comb teeth of the cleaning combs on each bracket will be inserted into the bristles of the cleaning brush, so as to ensure that each cleaning brush can be effectively cleaned.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-9 as shown, the present invention is a tool heat treatment device, including:

[0038] A box body 1, which is divided into a heating chamber 4 and a cooling chamber 5 by a retractable first baffle 101. The heating assembly 7 is fixedly installed symmetrically up and down in the heating chamber 4. The high-speed water flow nozzle 8 is slidably installed in the cooling chamber 5. The high-speed water flow nozzle 8 is driven by a first output source to move. A drain pipe 23 is opened on the bottom plate of the cooling chamber 5. A sliding frame 2 is slidably installed in the box body 1. The sliding frame 2 is driven by a third output source to move. A plurality of equally spaced clamping seats 201 are arranged thereon. Each clamping seat 201 clamps and fixes a tool body 3. When the first baffle 101 contracts, the heating chamber 4 and the cooling chamber 5 communicate;

[0039] The moving seat 9 is slidably installed in the cooling chamber 5 and is driven by a second output source to move. A plurality of brackets 12 arranged at equal intervals are fixedly installed on the moving seat 9. A cleaning brush 10 and two cleaning combs 13 are rotatably installed on each bracket 12. The cleaning brush 10 is driven by a first synchronization component to rotate. When the second output source drives the moving seat 9 to reciprocate below the tool body 3, both sides of each tool body 3 are respectively in contact with the bristles of the two cleaning brushes 10. The two cleaning combs 13 are symmetrically arranged with respect to the cleaning brush 10, and the comb teeth directions of the two cleaning combs 13 are opposite. The cleaning comb 13 is driven by a second synchronization component to rotate. When the cleaning comb 13 rotates to be in contact with the bristles of the cleaning brush 10, the comb teeth of the cleaning comb 13 are arranged in an interleaved manner with the bristles of the cleaning brush 10.

[0040] Wherein, a picking chamber 6 is arranged in the box body 1. The picking chamber 6 is separated from the cooling chamber 5 by a retractable second partition 102. When the second partition 102 contracts, the picking chamber 6 communicates with the cooling chamber 5.

[0041] In one case of this embodiment, the first output source, the second output source and the third output source can all be selected from components such as electric telescopic rods and reciprocating cylinders, and other mechanisms capable of realizing linear reciprocating motion can also be selected. This embodiment does not make specific limitations here; it should be noted that the clamping seat 201, the heating component 7 and the high-speed water flow nozzle 8 described in the present invention are all prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0042] When this embodiment is actually applied, as Figure 2 shown as an example, first, a plurality of tool bodies 3 are clamped and fixed on the sliding frame 2 through the clamping seat 201. When the first baffle 101 and the second partition 102 are fully contracted, at this time, the sliding frame 2 clamping and fixing a plurality of tool bodies 3 can move in the picking chamber 6, the cooling chamber 5 and the heating chamber 4. The tool body 3 is conveyed into the heating chamber 4, and the first baffle 101 is extended. The tool body 3 is heated at a high temperature by the heating component 7. Then the first baffle 101 is contracted, and then the tool body 3 is conveyed into the cooling chamber 5, and the first baffle 101 and the second partition 102 are extended. At this time, the high-speed water flow ejected by the high-speed water flow nozzle 8 cools the tool body 3. During this period, the high-speed water flow nozzle 8 moves back and forth under the drive of the first output source, so as to be able to cool each tool body 3;

[0043] When the tool body 3 comes into contact with high-speed water flow and oxidation scale and water scale are formed on its surface, the cleaning brush 10 is driven to rotate through the first synchronization component. Subsequently, the moving seat 9 is driven by the second output source to reciprocate below the tool body 3. Both sides of the tool body 3 are closely contacted by the bristles of the two rotating cleaning brushes 10. Through the continuous rotation of the cleaning brush 10, its bristles can effectively scrape and decompose the oxidation scale and water scale on the surface of the tool body 3, so as to quickly release the high-temperature heat in the tool body 3. Part of the cleaned debris will be discharged from the drain pipe 23 along with the water flow, and the other part will remain in the bristles of the cleaning brush 10. Driven by the second synchronization component, the cleaning comb 13 rotates to a state staggered with the cleaning brush 10. At this time, the teeth of the cleaning comb 13 and the bristles of the cleaning brush 10 are staggered in space. When the cleaning brush 10 rotates from cleaning one side of the tool body 3 to the other side of the tool body 3 during the rotation process, it will pass by the cleaning comb 13. This design enables the teeth of the cleaning comb 13 to effectively scrape and remove the debris retained in the bristles of the cleaning brush 10, ensuring the continuous cleaning state of the bristles. In this way, not only is it ensured that only clean bristles will contact the object tool body 3, avoiding the re-pollution of the object surface by the dirt mixed in the bristles, but also the potential impact damage to the surface of the tool body 3 caused by the dirt blocks mixed in the bristles is reduced.

[0044] As Figures 2-4 shown, as a preferred embodiment of the present invention, the clamping seat 201 is rotatably installed on the sliding frame 2 and is driven to rotate by the adjusting component 18. When the tool body 3 is located in the heating chamber 4, the adjusting component 18 drives the clamping seat 201 to rotate until the tool body 3 is in a vertical state. When the tool body 3 is in the cooling chamber 5 and the high-speed water flow nozzle 8 cools the tool body 3, the adjusting component 18 drives the clamping seat 201 to rotate until the tool body 3 is in a horizontal state. When the cleaning brush 10 cleans the tool body 3, the adjusting component 18 drives the clamping seat 201 to rotate until the tool body 3 is in a vertical state.

[0045] In the actual application of this embodiment, as Figure 3As shown in the example, when the tool body 3 is located in the heating chamber 4, the tool body 3 is in a vertical state. At this time, the tool body 3 is vertical to the heating component 7, which is in line with the processing method of the tool being vertical to the heating source during heat treatment. This method can ensure that the tool body 3 achieves ideal temperature distribution and uniformity during the heat treatment process, reduce deformation and cracks, and improve mechanical properties and production efficiency. When the tool body 3 is located in the cooling chamber 5 and is about to be cooled, the adjustment component 18 drives the clamping seat 201 to make the tool body 3, which was originally in a vertical state, rotate smoothly to a horizontal position. This posture adjustment ensures that the high-speed water flow ejected by the high-speed water flow nozzle 8 can fully cover the front of the tool body 3, greatly expanding the contact area of ​​direct cooling, thereby accelerating the transfer and dissipation of heat. After the cooling process is successfully completed, the tool body 3 returns to the vertical state. At this moment, the pre-deployed cleaning brush 10 enters the working state, thereby carrying out oxide scale and scale removal operations on the tool body 3.

[0046] like Figure 9 As shown, as a preferred embodiment of the present invention, the adjustment component 18 includes a rack plate 19, a gear 20 and an electric cylinder 21. The number of the gears 20 is consistent with the number of the clamping seat 201. The gears 20 are fixedly installed on the rotating shaft of the clamping seat 201, and the two are coaxially arranged. The rack plate 19 is slidably installed in the sliding frame 2, and it is meshed with the gear 20. The electric cylinder 21 is fixedly installed in the sliding frame 2, and its movable end is fixedly connected to the rack plate 19.

[0047] In one case of this embodiment, it should be noted that the electric cylinder 21 described in the present invention is the prior art, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0048] In actual application of this embodiment, as shown in the moving seat 9 in the figure, when the electric cylinder 21 is fully extended, it will push the rack plate 19 to move, thereby driving the gear 20 to rotate ninety degrees clockwise. At this time, the clamping seat 201 will drive the tool body 3 to rotate ninety degrees clockwise to a horizontal state. Then, when the electric cylinder 21 is fully retracted, the movement of the rack plate 19 will drive the gear 20 to rotate one hundred and eighty degrees counterclockwise, thereby driving the tool body 3 to flip one hundred and eighty degrees, so that both sides of the tool body 3 can receive the cooling of the high-speed water flow sprayed by the high-speed water flow nozzle 8.

[0049] like Figures 5-6 As shown, as a preferred embodiment of the present invention, the first synchronous component includes a first synchronous belt 11 and a first driving source, the rotating shafts of two adjacent cleaning brushes 10 are connected by the first synchronous belt 11, and one cleaning brush 10 is driven to rotate by the first driving source.

[0050] In one case of this embodiment, the first driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0051] In actual application of this embodiment, when the first driving source drives a cleaning brush 10 to rotate, the transmission action of the first synchronous belt 11 causes each cleaning brush 10 to rotate synchronously, thereby ensuring that the cleaning brush 10 can synchronously perform descaling and cleaning work on the tool body 3.

[0052] like Figures 5-7 As shown, as a preferred embodiment of the present invention, the second synchronous component includes a second synchronous belt 14, a driving wheel 15, a driven wheel 16 and a third synchronous belt 17, the rotating shafts of the two cleaning combs 13 located on the bracket 12 are connected by the second synchronous belt 14, one cleaning comb 13 is driven to rotate by the second driving source, the driving wheel 15 is fixedly mounted on the rotating shaft of one cleaning comb 13, and the two are coaxially arranged, the driven wheel 16 is fixedly mounted on the rotating shaft of the other cleaning comb 13, and the two are coaxially arranged, the driving wheel 15 and the driven wheel 16 on two adjacent brackets 12 are connected by the third synchronous belt 17, and multiple third synchronous belts 17 are parallel to each other.

[0053] In one case of this embodiment, the second driving source may be a servo motor, a servo motor or other components, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0054] In actual application of this embodiment, when the second driving source drives a cleaning comb 13 to rotate, the cleaning comb 13 will first drive another cleaning comb 13 located on the same bracket 12 to rotate through the second synchronous belt 14, and the rotation direction is the same. Figure 7 As shown in the example, the two cleaning combs 13 will rotate toward the middle at the same time, and the rotation of the cleaning comb 13 will drive the driving wheel 15 to rotate, and through the transmission action of the third synchronous belt 17, the cleaning combs 13 on the adjacent brackets 12 will be driven to rotate, so that the comb teeth of the cleaning comb 13 on each bracket 12 will be inserted into the bristles of the cleaning brush 10, thus ensuring that each cleaning brush 10 can be effectively cleaned.

[0055] like Figures 1-4 As shown, as a preferred embodiment of the present invention, a blowing port 22 is provided in the cooling chamber 5, the blowing port 22 is connected to the cold air device, and is located below the high-speed water flow nozzle 8, and when the sliding frame 2 is located in the cooling chamber 5, the blowing port 22 faces the tool body 3.

[0056] In a case of this embodiment, components such as a cold air blower, a refrigerator, and a compressor can be selected for the cold air device, and specific limitations are not made herein in this embodiment.

[0057] In actual application of this embodiment, cold air is blown into the tool body 3 through the air outlet 22 by the cooling device, so as to accelerate the cooling effect of the tool body 3.

[0058] As Figures 1-4 shown, as a preferred embodiment of the present invention, an air suction port 24 is provided on the top plate of the cooling chamber 5, and the air suction port 24 is communicated with an air extraction device.

[0059] In a case of this embodiment, components such as a centrifugal fan and an axial flow fan can be selected for the air extraction device, and specific limitations are not made herein in this embodiment.

[0060] In actual application of this embodiment, when the high-speed water flow ejected by the high-speed water flow nozzle 8 passes through the high-temperature tool body 3, a large amount of smoke and fog will be generated. The air extraction device can suck away the smoke and fog through the air suction port 24, avoiding the problems that the smoke and fog affect the cleanliness of the working environment and pose a threat to the health of the operators.

[0061] Please refer to Figures 1-9 shown, the present invention is a processing method of a tool heat treatment device. The method is applied to a tool heat treatment device as described in the above embodiment, and the method includes the following steps:

[0062] Step S1: First, a plurality of tool bodies 3 are clamped and fixed in sequence by the sliding rack 2. The first baffle 101 is retracted. After the driving source drives the sliding rack 2 to move into the heating chamber 4, the first baffle 101 is extended, and then the tool body 3 is heated at a high temperature by the heating component 7;

[0063] Step S2: The first baffle 101 is retracted. After the driving source drives the sliding rack 2 to move from the heating chamber 4 to the cooling chamber 5, the first baffle 101 is extended, and then the first output source drives the high-speed water flow nozzle 8 to reciprocate and eject high-speed water flow to cool the tool body 3;

[0064] Step S3: When oxidation scale is formed on the surface of the tool body 3, the first synchronization component drives the cleaning brush 10 to rotate, and then the second output source drives the moving seat 9 to move, so that the cleaning brush 10 contacts the tool body 3. At this time, two adjacent cleaning brushes 10 can clean both sides of a tool body 3;

[0065] Step S4: When excessive dirt accumulates on the cleaning brush 10, the cleaning comb 13 is driven by the second synchronization component to rotate until it contacts the cleaning brush 10. At this time, when the cleaning brush 10 rotates from one side of a tool body 3 to the other side of the tool body 3, it will be cleaned by the cleaning comb 13 during the process.

[0066] Step S5: After the tool body 3 has completely cooled down, the moving seat 9 resets, and then the tool bodies 3 are taken out one by one.

[0067] Working principle of the present invention: In the above embodiments of the present invention, a tool heat treatment device and its treatment method are provided. First, the tool body 3 is transported into the heating chamber 4 for high-temperature heating, and then the tool body 3 is transported into the cooling chamber 5 for cooling treatment. The tool body 3 is mainly cooled by the high-speed water flow ejected from the high-speed water flow nozzle 8. When the tool body 3 contacts the high-speed water flow and oxidation scale and water scale are formed on its surface, the cleaning brush 10 is driven to rotate by the first synchronization component. Subsequently, the moving seat 9 is driven by the second output source to reciprocate below the tool body 3. Both sides of the tool body 3 are closely contacted by the bristles of the two rotating cleaning brushes 10. Through the continuous rotation of the cleaning brush 10, its bristles can effectively scrape and decompose the oxidation scale and water scale on the surface of the tool body 3. Driven by the second synchronization component, the cleaning comb 13 rotates to a state where it intersects with the cleaning brush 10. At this time, the teeth of the cleaning comb 13 and the bristles of the cleaning brush 10 are arranged alternately in space. When the cleaning brush 10 rotates from cleaning one side of a tool body 3 to the other side of the tool body 3 during the rotation process, it will pass by the cleaning comb 13. This design enables the teeth of the cleaning comb 13 to effectively scrape and remove the debris retained in the bristles of the cleaning brush 10.

[0068] The above has described in detail one embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
