Description

Technical Field

[0001] This invention relates to the field of quenching equipment technology, and more specifically to a cooling device for cutting tools after heat treatment. Background Technology

[0002] The main purpose of heat treatment for cutting tools is to improve the internal structure of the steel, thereby obtaining superior material properties. Through heat treatment, the hardness, strength, toughness, wear resistance, and corrosion resistance of the cutting tools can be improved, enabling them to remain sharp and less prone to deformation and breakage during use, thus extending their service life.

[0003] Tool heat treatment mainly includes four basic processes: annealing, normalizing, quenching, and tempering. Among them, quenching involves heating the tool to a certain temperature and then rapidly cooling it. Quenching is a key step in improving the hardness of the tool, and commonly used cooling media include oil, water, and brine. The quenching process requires strict control of heating temperature and cooling rate to avoid cracking or deformation of the tool.

[0004] The existing tool quenching equipment has some shortcomings in its use, as follows:

[0005] Existing quenching equipment requires clamping the tool to be quenched using a clamping assembly and then placing it in a cooling medium for cooling, or placing the tool in a quenching frame and immersing it in the cooling medium to complete the quenching. However, existing equipment completely immerses the tool in the cooling medium during use, essentially keeping it in a static state, resulting in low efficiency of the cooling medium. Furthermore, frequent use of the existing cooling medium can cause its temperature to rise, which is detrimental to the preservation of the cooling medium and improving cooling efficiency. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling device for cutting tools after heat treatment, so as to solve the problems existing in the background art.

A second transmission wheel is fixedly connected to the inside of the fourth roller on the other side of the two first fixed plates. A first transmission wheel is fixedly connected to the back of the third roller. A transmission belt is provided on the outer side of the first transmission wheel and the second transmission wheel. A fourth arc surface is provided at the bottom of the second stop block.

[0011] Furthermore, the transmission assembly includes a quenching push belt, with a connecting hole on the outer side of the quenching push belt, and a positioning slide rail fixedly connected to the outer side of the quenching push belt, with square positioning notches on both sides of the positioning slide rail.

[0012] Furthermore, the quenching partition assembly includes a positioning sliding plate. The positioning sliding plate has a sliding positioning groove on the side near the transmission assembly. Positioning blocks are fixedly connected to both the front and back sides of the positioning sliding plate away from the transmission assembly. A rotating shaft is installed on the inner side of the two positioning blocks. A torque assembly is installed on the outer side of the rotating shaft. A rotating push plate is installed on the inner side of the rotating shaft. A square groove is opened on the top of the rotating push plate. An inclined surface is opened on the side of the rotating push plate away from the positioning sliding plate.

[0013] Furthermore, the distance between one side of the second roller shaft and one side of the interior of the second quenching box body is the same as the distance between one side of the first roller shaft and one side of the interior of the first quenching box body and the inner side of the arc-shaped baffle. The side of the quenching partition assembly away from the transmission assembly is attached to the top of the second quenching box body, the first quenching box body, and the arc-shaped baffle. The diameter and number of the central guide holes are the same as the diameter and number of the guide pipes.

[0014] Furthermore, the center line of the second arc surface is at the same position as the center line of the second stop, the diameter of the arc-shaped notch is in clearance fit with the diameters of both sides of the conveyor belt, the top of the conveyor belt is on the same plane as the lowest point of the third arc surface, and the thickness of the first stop and the thickness of the second stop are the same.

[0015] Furthermore, the shape and size of the sliding positioning groove are clearance-fitted with the positioning slide rail and the square positioning notch; the length of the quenching partition assembly is the same as the width of the transmission assembly; the width of the transmission assembly is the same as the inner width of the first quenching box assembly; and the inner widths of the first quenching box assembly, the second quenching box assembly, and the third quenching box assembly are the same.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. In this invention, after the cutting tool is heated, it is placed on top of the quenching partition assembly located inside the main body of the second quenching box. Then, a servo motor drives the fourth roller shaft to rotate, which in turn drives the first gear to rotate. The meshing of the first and second gears drives the second gear to rotate, which in turn drives the second transmission wheel to rotate. Then, under the transmission belt, the first transmission wheel rotates, causing the third roller shaft to rotate. With the positioning of the second and first roller shafts, the transmission assembly rotates, which in turn moves the quenching partition assembly outside the transmission assembly. When the quenching partition assembly moves to the inside of the main bodies of the second and first quenching boxes, the cutting tool can be quenched in the cooling medium inside the main bodies of the first and second quenching boxes. During the rotation, the cutting tool to be quenched can be placed on top of each quenching partition assembly. During the quenching process, the cutting tool moves in the cooling medium, so that the cutting tool is not directly immersed in the medium. The cooling medium in contact with the cutting tool changes continuously during the movement of the cutting tool, which accelerates the cooling speed of the cutting tool and ensures the quenching efficiency of the cutting tool.

[0018] 2. In this invention, when the quenching partition assembly moves into the interior of the third quenching box assembly, the cutting tool is pushed by the quenching partition assembly located behind the cutting tool, thereby placing the cutting tool at the top of the quenching partition assembly. As the quenching partition assembly continues to rise inside the third quenching box assembly, passing through the fourth arc surface, the rotating push plate rotates along the rotation axis, causing the inclined surface to adhere to the fourth arc surface. During the continuous rotation of the transmission assembly, when the inclined surface adheres to one side of the second stop, the cutting tool can slide down along the inclined surface to adhere to the second stop, and the cutting tool has already detached from the cooling medium. The cooling medium adhering to the outside of the cutting tool can be separated through the square groove. Then, as it continues to rise to the top of the second stop, the cutting tool slides onto the third arc surface, and then falls to the top of the conveyor belt. When the cutting tool falls to the top of the conveyor belt, it will be transported away by the conveyor belt. This achieves automatic detachment of the cutting tool from the cooling medium after quenching and can separate the cooling medium, ensuring the quenching efficiency of the cutting tool.

[0019] 3. During the movement of the quenching partition assembly, the present invention generates a rightward pushing force on the cooling medium inside the first quenching box assembly, thereby causing the cooling medium to be replaced through the U-shaped conveying pipe. The first and second fans cool the cooling medium located inside the U-shaped conveying pipe, ensuring that the temperature of the cooling medium inside the equipment does not become too high. The third quenching box assembly can be connected to the medium inside the second quenching box assembly through the guide pipe. Since the tool temperature is high when it first enters the cooling medium, the temperature of the cooling medium inside the second quenching box assembly is high, while the temperature inside the third quenching box assembly is lower, causing the cooling medium to circulate. The first fan cools the cooling medium inside the guide pipe.

[0020] 4. This invention can be used in processing steps where special quenching requirements are needed, i.e., after the workpiece has been initially quenched and cooled by quenching oil, and then needs to be cooled down quickly, by filling the inner side of the third quenching box assembly and the second quenching box assembly with quenching oil, and filling the inner side of the first quenching box assembly with quenching water. Since oil and water are incompatible, the equipment can be adjusted according to the actual construction and processing requirements, making it convenient for users to use.

Then, the transmission belt 4... The transmission of 020 drives the first transmission wheel 4018 to rotate, which in turn causes the third roller shaft 404 to rotate. Under the positioning of the second roller shaft 204 and the first roller shaft 103, the transmission assembly 6 rotates, which in turn drives the quenching partition assembly 7 to move outside the transmission assembly 6. When the quenching partition assembly 7 moves to the inside of the second quenching box body 201 and the first quenching box body 101, the tool quenching process can be carried out in the cooling medium located inside the first quenching box body 101 and the second quenching box body 201. During the rotation, the tool to be quenched can be placed on the top of each quenching partition assembly 7, so that the tool moves in the cooling medium during the quenching process. The tool is not directly immersed in the medium.

A fourth arc surface 4021 is opened at the bottom of the second stop block 409. When the quenching partition assembly 7 moves into the interior of the third quenching box assembly 4, the tool will be pushed by the quenching partition assembly 7 located behind the tool, so that the tool is located on the top of the quenching partition assembly 7. The quenching partition assembly 7 continues to rise inside the third quenching box assembly 4, passing through the fourth arc surface 4021, so that the rotating push plate 706 rotates along the rotating shaft 704, so that the inclined plane 70 When the fourth arc surface 4021 is in contact with the cutting edge 708 and the transmission component 6 is continuously rotating, the cutting tool can slide down along the inclined surface 708 to contact the second stop 409. The cutting tool has already detached from the cooling medium. The cooling medium adhering to the outside of the cutting tool can be separated through the square groove 707. Then, when it continues to rise to the top of the second stop 409, the cutting tool falls onto the third arc surface 4010 and then falls to the top of the conveyor belt 4015. When the cutting tool falls onto the top of the conveyor belt 4015, it will be transported away by the conveyor belt 4015.

A rotating push plate 706 is installed on the inner side of the rotating shaft 704. A square groove 707 is opened on the top of the rotating push plate 706. An inclined surface 708 is opened on the side of the rotating push plate 706 away from the positioning sliding plate 701.

[0037] In a preferred embodiment, the distance between one side of the second roller 204 and the inside of the second quenching box body 201 is the same as the distance between one side of the first roller 103 and the inside of the arc-shaped baffle 102 inside the first quenching box body 101. The side of the quenching partition assembly 7 away from the transmission assembly 6 is attached to the top of the second quenching box body 201, the first quenching box body 101, and the arc-shaped baffle 102. The diameter and number of the central guide holes 203 are the same as the outer diameter and number of the guide tubes 402.

[0038] In a preferred embodiment, the center line of the second arc surface 408 is at the same position as the center line of the second stop 409, the diameter of the arc notch 4011 is in clearance fit with the diameters of both sides of the conveyor belt 4015, the top of the conveyor belt 4015 is on the same plane as the lowest point of the third arc surface 4010, and the thickness of the first stop 406 is the same as the thickness of the second stop 409.

[0039] In a preferred embodiment, the shape and size of the sliding positioning groove 702 are clearance-fitted with the positioning slide rail 603 and the square positioning notch 604, the length of the quenching partition assembly 7 is the same as the width of the transmission assembly 6, the width of the transmission assembly 6 is the same as the width of the inner side of the first quenching box assembly 1, and the inner widths of the first quenching box assembly 1, the second quenching box assembly 2, and the third quenching box assembly 4 are the same.

[0040] The working principle of this invention is as follows: After the tool is heated, it is placed on top of the quenching partition assembly 7 located inside the main body 201 of the second quenching box. Then, the servo motor 4014 drives the fourth roller shaft 4013 to rotate, thereby driving the first gear 4022 to rotate. Then, the meshing of the first gear 4022 and the second gear 4023 drives the second gear 4023 to rotate, which in turn drives the second transmission wheel 4019 to rotate. Then, under the transmission of the transmission belt 4020, the first transmission wheel 4018 rotates, which causes the third roller shaft 404 to rotate. Under the positioning of the second roller shaft 204 and the first roller shaft 103, the transmission assembly... 6 rotates, which in turn drives the quenching partition assembly 7 to move outside the transmission assembly 6. When the quenching partition assembly 7 moves to the inside of the second quenching box body 201 and the first quenching box body 101, the tool quenching process can be carried out in the cooling medium inside the first quenching box body 101 and the second quenching box body 201. During the rotation, the tool to be quenched can be placed on the top of each quenching partition assembly 7. During the quenching process, the tool moves in the cooling medium, so that the tool is not directly immersed in the medium. During the movement of the tool, the cooling medium in contact with the tool is constantly changing, which speeds up the cooling speed of the tool and ensures the quenching efficiency of the tool.

[0041] When the quenching partition assembly 7 moves into the interior of the third quenching box assembly 4, the cutting tool is pushed by the quenching partition assembly 7 located behind the cutting tool, thereby placing the cutting tool on top of the quenching partition assembly 7. As the quenching partition assembly 7 continues to rise inside the third quenching box assembly 4, passing the fourth arc surface 4021, the rotating push plate 706 rotates along the rotation axis 704, causing the inclined surface 708 to adhere to the fourth arc surface 4021. During the continuous rotation of the transmission assembly 6, when the inclined surface 708 adheres to one side of the second stop block 409, the cutting tool can slide downwards along the inclined surface 708 to adhere to the second stop block 409. Having detached from the cooling medium, the tool can be separated from the cooling medium adhering to its outer side via the square groove 707. Then, as it continues to rise to the top of the second stop 409, the tool slides onto the third arc surface 4010 and continues until it falls to the top of the conveyor belt 4015. When the tool falls onto the top of the conveyor belt 4015, it will be transported away by the conveyor belt 4015. When the quenching partition assembly 7 moves to the first arc surface 407, the torque assembly 705 causes the quenching partition assembly 7 to return to its original position. This achieves automatic detachment of the tool from the cooling medium after quenching and ensures the quenching efficiency of the tool.

[0042] During the movement of the quenching partition assembly 7, a pushing force is generated to the right on the cooling medium inside the first quenching box assembly 1, which in turn causes the cooling medium to be replaced through the U-shaped conveying pipe 105. The cooling medium inside the U-shaped conveying pipe 105 is cooled by the first fan 3 and the second fan 5, so that the temperature of the cooling medium inside the equipment is not too high. The medium inside the third quenching box assembly 4 can be connected to the medium inside the second quenching box assembly 2 through the guide pipe 402. Since the temperature of the tool that just enters the cooling medium is high, the temperature of the cooling medium inside the second quenching box assembly 2 is high, while the temperature inside the third quenching box assembly 4 is low, which causes the cooling medium to circulate. The cooling medium inside the guide pipe 402 is cooled by the first fan 3.

[0043] In addition, for special quenching requirements, such as when the workpiece needs to be cooled down quickly after initial quenching and cooling with quenching oil, the inner side of the third quenching box assembly 4 and the second quenching box assembly 2 are filled with quenching oil, and the inner side of the first quenching box assembly 1 is filled with quenching water. Since oil and water are incompatible, the equipment can adjust the quenching process according to the actual construction and processing requirements, making it convenient for users.
