Description

Technical Field

[0001] The utility model belongs to the technical field of quenching, and in particular relates to a quenching device. Background Art

[0002] Quenching is a heat treatment process. Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept at this temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solution treatment or heat treatment process with rapid cooling process of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass is usually called quenching.

[0003] The quenching of industrial chains is particularly important in industrial processing, and is the key to ensuring the normal operation of large equipment. After searching, the "quenching device" disclosed in the Chinese patent application number "CN202222473169.1" includes a quenching pool, a water outlet is provided at the bottom right end of the quenching pool, and a first cleaning piece is provided on the side of the bottom end of the inner wall of the quenching pool. The first cleaning piece includes a cylinder, a vertical plate is connected to the top of the cylinder, and a card block is embedded in the left side of the bottom end of the vertical plate through a card slot, and a filter plate is connected to the left side of the card block, and the filter plate is attached to the inner wall of the quenching pool. The utility model realizes the cleaning of austenite residue by setting a first cleaning piece. Compared with the traditional structure, the device pushes the vertical plate at the output end of the cylinder to drive the filter plate to move. The filter plate salvages and cleans the water pool in the quenching pool during movement to prevent the residue from affecting the forgings such as aluminum profiles that are subsequently quenched.

[0004] Although the patent solves the problem of salvaging and cleaning the water in the quenching pool to prevent residues from affecting the subsequent quenched aluminum profiles and other forgings, the surface temperature of the industrial chain after quenching is very high. When cooling in the quenching pool, the temperature of the surface of the industrial chain will cause the cooling water to boil, and the boiling cooling water is easy to splash out of the quenching pool. The splashed cooling water has a certain temperature, which can cause burns to employees when splashed onto them. Utility Model Content

[0028] Preferably, the filter screen 7 is made of metal, a through hole is formed in the outer frame of the filter screen 7 , a threaded groove is formed on the top surface of the fixing block 8 , and the filter screen 7 is threadedly fixedly connected to the fixing block 8 through screws 9 .

[0029] During specific use, the filter screen 7 is fixed to the fixing block 8 by means of screws 9, thereby preventing the cooling water from forming water waves when the chain is taken out back and forth and affecting the normal use of the filter screen 7, thereby improving the stability of the use of the filter screen 7.

[0030] Preferably: the adjustment mechanism includes a mounting block 10, a support block 11, a connecting rod 12, a movable block 13, a screw 14, a threaded sleeve 15, a servo motor 16 and a control button 17, the mounting block 10 is mounted inside the top of the quenching pool 1, the support block 11 is mounted inside the top of the quenching pool 1 relative to the mounting block 10, two mounting blocks 10 and two support blocks 11 are provided, the connecting rod 12 is fixedly connected between the two mounting blocks 10, the movable block 13 is movably connected to the surface of the connecting rod 12, the screw 14 is rotatably connected between the two support blocks 11, the threaded sleeve 15 is threadedly connected to the surface of the screw 14, the servo motor 16 is mounted on the outer wall of a support block 11 and the output shaft is connected to one end of the screw 14 through a coupling, and the control button 17 is mounted on the outer wall of the quenching pool 1.

[0033] When in use, the movement of the thread sleeve 15 generated by the rotation of the screw rod 14 is transmitted to the movable block 13 through the double-opening plate 5, thereby driving the movable block 13 to move along the surface of the connecting rod 12, thereby increasing the convenience of opening.

[0038] Working principle: When the chain is quenched, the chain is stored in the quenching pool 1 and quenched through the quenching cylinder 4. After the chain is quenched, the control button 17 is operated to start the servo motor 16 to work. Then, the output shaft of the servo motor 16 drives the screw rod 14 to rotate. After the screw rod 14 rotates, the thread sleeve 15 moves away from or towards each other along the thread on the surface of the screw rod 14. At the same time, the movement of the thread sleeve 15 allows the double-open plate 5 connected to the top to open or close. Then, the other end of the double-open plate 5 drives the movable block 13 to move along the connecting rod 12, and the movement trajectory of the movable block 13 is the same as the movement trajectory of the thread sleeve 15. Then, the closing of the double-open plate 5 covers the quenching pool 1, allowing the chain quenched by the quenching cylinder 4 to be lowered into the quenching pool through professional tools. 1, and the closed double-open plate 5 blocks the splashing of boiling water when the chain is cooled, thereby avoiding scalding employees. At the same time, the opening of the double-open plate 5 also makes it convenient to store the chain in the quenching pool 1 for quenching. When the chain is cooled, the surface oxide scale enters the cooling water inside the quenching pool 1, and the filter screen 7 installed inside the quenching pool 1 divides the cooling water inside the quenching pool 1 into an upper layer and a lower layer, so that the fallen oxide scale can only be in the upper layer of the filter screen 7. Then, when the control valve 3 is opened to drain water at a later stage, the oxide scale will not be discharged together, reducing pollution to the environment. At the same time, as the cooling water is discharged, the oxide scale will be filtered out on the surface of the filter screen 7, and then, the filter screen 7 can be removed from the inside of the quenching pool 1 by the screws 9 installed by the tool for cleaning or replacement.

[0039] It should be noted that the interior of the quenching water tank 1 is provided with recesses for installing the mounting block 10 and the supporting block 11 ( Figure 3 ), and also leave the activity interval of the wire sleeve 15 and the movable block 13 (not shown in the figure), then the screw rod 14 belongs to the bidirectional screw rod ( Figure 5 As shown in the figure, the screw rod 14 can drive the screw sleeve 15 to move away from and towards each other during the rotation process. Subsequently, the terminal of the servo motor 16 and the control button 17 are connected in series, and the terminal of the servo motor 16 is connected to the power supply equipment. The series control button 17 can start the servo motor 16 to work. At the same time, the servo motor 16 is a three-phase motor that supports forward and reverse rotation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
