Description

Technical Field

[0001] The utility model relates to the technical field of knife blank quenching, in particular to a knife blank heat treatment quenching device. Background Art

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

[0003] For example, patent document CN 210261884 U discloses a heat treatment quenching and cooling device for blade blanks, comprising a frame, a lifting frame mounted on the frame, an oil tank mounted below the lifting frame, and a first driving mechanism mounted on the frame for driving the lifting frame to move upward and downward, wherein the lifting frame is provided with a blade blank clamping mechanism, and the lifting frame is slidably connected to the frame. When the utility model is used, a high-temperature blade blank is placed on the blade blank clamping mechanism, and the lifting frame is driven upward and downward by the first driving mechanism, so that the lifting frame drives the blade blank clamping mechanism and the blade blank to move and immerse in the quenching liquid in the oil tank and rise above the liquid level, thereby achieving automatic control of the quenching treatment of the blade blank, eliminating the need for manual clamping of the blade blank close to the oil tank to immerse the blade blank in the quenching liquid for quenching, thereby improving work safety.

[0004] However, due to the limitations of its own structure, this structure can only perform open-type heat treatment and quenching of the blade blank during heat treatment and quenching. During this process, a large amount of steam and harmful heavy metal substances will still be generated. Long-term operation will have an impact on the surrounding environment. At the same time, the equipment cannot perform more stable quenching and loading and unloading operations for the blade blank, and cannot meet daily use needs. Therefore, it is urgent to design a blade blank heat treatment and quenching device to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a knife blank heat treatment and quenching device to solve the problem proposed in the above background technology that the existing structure can only perform open knife blank heat treatment and quenching due to its own structural limitations. During this process, a large amount of steam and harmful heavy metal substances floating with the steam will still be generated. Long-term operation will have an impact on the surrounding environment. At the same time, the equipment cannot perform more stable quenching and loading and unloading operations for the knife blank, and cannot meet daily usage needs.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a heat treatment quenching device for a blade blank, comprising a quenching box, a first sealing cover movably connected to one side of the top of the quenching box, a second sealing cover movably connected to the other side of the top of the quenching box, and a lifting tray movably connected to the interior of the quenching box;

[0007] A lifting frame is fixedly connected to the bottom center of the quenching box, and both ends of the lifting frame are fixedly connected to limited side frames. A lifting airbag is provided inside the lifting frame.

[0008] Preferably, the top end of the lifting airbag is fixedly connected to a lifting plate, and a lifting rubber seat is provided on the surface of the lifting plate.

[0009] Preferably, limiting sliding grooves are provided on both sides of the inner wall of the quenching box, and limiting sliding blocks are fixedly connected to both sides of the lifting tray.

[0010] Preferably, the surface of the lifting tray is evenly provided with liquid seepage holes and the inner wall of the limiting side frame is provided with a limiting lining.

[0011] Preferably, movable bars are fixedly connected to both ends of the surface of the quenching box, and movable side blocks are fixedly connected to both ends of the movable bar.

[0012] Preferably, a sealing strip is provided between the quenching box and the first sealing cover and the second sealing cover, and a magnetic strip is provided between the first sealing cover and the second sealing cover.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The knife blank heat treatment quenching device, through the quenching box, the first sealing cover, the second sealing cover, the lifting tray, the movable bar, the movable side block, the sealing strip and the magnetic strip, can make the equipment carry out the heat treatment quenching operation of the knife blank more safely at any time. In the actual use process, the staff first puts the knife blank into the interior of the quenching box and arranges it neatly on the surface of the lifting tray. Then the staff simultaneously moves the first sealing cover and the second sealing cover on both sides of the surface of the quenching box to make them dock toward the center of the surface of the quenching box. At this time, the first sealing cover and the second sealing cover are separated. In addition, the internal limited sliding operation can be performed at the movable bars and movable side blocks at both ends of the quenching box surface, and then the docking operation can be quickly performed on the surface of the quenching box. During docking, the first sealing cover and the second sealing cover are sealed and fitted with the surface of the quenching box through sealing strips, and the first sealing cover and the second sealing cover are directly adsorbed and fixed more tightly through magnetic strips, so that the smoke generated during the subsequent heat treatment and quenching of the knife blank inside the quenching box can be sealed and connected through the first sealing cover and the second sealing cover, and re-precipitated back into the interior of the quenching box to avoid outflow, which reflects the practicality of the equipment design.

[0015] The knife blank heat treatment quenching device further improves the overall use effect of the equipment by providing a quenching box, a lifting frame, a limiting side frame, a lifting airbag, a lifting plate, a lifting rubber seat, a limiting slide groove, a limiting slider, a seepage hole groove and a limiting lining. During daily use, the staff can start the lifting airbag inside the lifting frame, so that it can adapt to the lifting plate and the lifting rubber seat at the top to perform the lifting and adjusting operation of the lifting tray inside the quenching box at the bottom center. At the same time, during the lifting process, the seepage holes on both sides of the lifting tray can be limited and slid at the limiting slide grooves on both sides of the inner wall of the quenching box. At this time, the limiting lining inside the limiting side frame performs a stable damping limiting operation, thereby ensuring the stability of the knife blank heat treatment quenching at all times, reflecting the comprehensiveness of the equipment design.

[0024] Lifting frame 5, the bottom center of the quenching box 1 is fixedly connected with a lifting frame 5, both ends of the lifting frame 5 are fixedly connected to the limited side frames 6, a lifting airbag 7 is arranged inside the lifting frame 5, the top of the lifting airbag 7 is fixedly connected with a lifting plate 8, the surface of the lifting plate 8 is provided with a lifting rubber seat 9, and limited sliding grooves 10 are provided on both sides of the inner wall of the quenching box 1, and limited sliding blocks 11 are fixedly connected on both sides of the lifting tray 4.

[0025] Working principle: When in use, the user first puts the knife blank into the interior of the quenching box 1 and arranges it neatly on the surface of the lifting tray 4.

At this time, the limit lining 13 inside the limit side frame 6 performs a stable damping limit operation, thereby ensuring the stability of the heat treatment and quenching of the blade blank at all times. The above is the entire working principle of the present utility model.
