Description

Technical Field

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

[0002] The casting safety quenching device is a device specially designed for the casting quenching process, wherein the casting safety quenching device is mainly composed of a box, a heater, a thermometer and a timer, a water inlet pipe and a flow meter. When the casting safety quenching device is used, after heating to a predetermined temperature, the casting is kept at a high temperature for a period of time to ensure that the temperature inside the casting is uniform, and then the high-temperature casting is quickly immersed in the quenching medium. Finally, after the quenching is completed, the fan provides a forced cooling effect to accelerate the cooling speed of the casting. Subsequently, the quenching medium is discharged through the drain pipe, and the overflow pipe is used to prevent the medium from overflowing. The casting safety quenching device is suitable for quenching treatment of castings of various materials and shapes.

[0003] For example, the Chinese patent "A High-Safety Mechanical Casting Quenching Device" with announcement number CN220767074U includes an operating base plate, a pair of sliding blocks are connected to the upper end of the operating base plate, and the upper end of the sliding block is fixedly connected to a hydraulic lifting rod, and the upper end of the pair of hydraulic lifting rods is fixedly connected to a rectangular load-bearing rod, and a quenching assembly is provided in the middle of the rectangular load-bearing rod, and the upper end of the operating base plate is fixedly connected to a quenching pool and a cooling pool, and the quenching assembly includes a drive shell fixedly connected to the upper end of the rectangular load-bearing rod, and the lower end of the rectangular load-bearing rod is fixedly connected to the upper end of the driving shell. The end is also fixedly connected to a mounting shell, the interior of the mounting shell is rotatably connected to a rotating mounting ring, the lower end of the rotating mounting ring is fixedly connected to a rotating sleeve, the lower end of the rotating sleeve is fixedly connected to a fixed mounting ring, the interior of the rotating sleeve is rotatably connected to a rotating shaft, the interior of the rotating sleeve is fixedly connected to a semicircular protrusion, and the middle part of the rotating shaft is fixedly connected to a rectangular protrusion that rotates with the semicircular protrusion, the middle upper end of the rotating shaft and the interior of the driving shell is fixedly connected to a driven gear, and the interior of the driving shell is fixedly connected to a servo motor.

[0004] Although the above-mentioned prior art can realize the quenching of castings, in actual use, on the one hand, it is difficult to provide protection for operators when the castings are quenched. When the castings are placed in the quenching pool, the quenching liquid is easily splashed everywhere due to the impact of the castings, causing the splashed quenching liquid to drop on the skin surface of the operator, thereby posing a threat to the personal safety of the operator. On the other hand, the quenching effect of the contact part between the hook and the casting is not good enough. When the castings are quenched, the contact part between the hook and the casting will cause obstruction, thereby affecting the quenching quality. Therefore, it does not meet the existing needs. In this regard, we propose a casting safety quenching device. Utility Model Content

[0005] The utility model aims to provide a casting safety quenching device to solve the problems in the above background technology that it is difficult to provide protection for operators when quenching castings and the quenching effect of the contact part between the hook and the casting is not good enough.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a casting safety quenching device, comprising a quenching tank, one side of the quenching tank is an open structure, support rods are fixedly arranged at the four corners of the lower end of the quenching tank, a rotating rod is arranged above the interior of the quenching tank, an arc-shaped baffle is fixedly arranged on one side of the rotating rod, a slide groove is arranged inside the lower end of the quenching tank, the lower end of the arc-shaped baffle extends to the interior of the slide groove, and the arc-shaped baffle and the slide groove are slidably limited.

[0007] Preferably, fixing rods are fixedly provided on both sides of the arc-shaped baffle plate inside the slide groove, and pulleys are provided outside the fixing rods, and the pulleys are slidably matched with the slide groove.

[0008] Preferably, a motor is fixedly provided at the upper end of the quenching tank, and an output shaft of the motor extends into the interior of the quenching tank and is fixedly connected to the rotating rod.

[0009] Preferably, a mounting seat is fixedly provided at the lower end of the quenching tank located inside the slide groove, a quenching pool is fixedly provided at the middle position of the upper end of the mounting seat, an overflow tank is provided at the upper end inside the quenching pool, and the overflow tank is connected to the quenching pool.

[0010] Preferably, four drain pipes are fixedly provided inside the side wall of the quenching pool, and the drain pipes are equidistantly distributed in a ring shape, the upper ends of the drain pipes are connected to the overflow trough, and the lower ends of the drain pipes extend to the lower end of the quenching tank.

[0011] Preferably, a hydraulic telescopic device is fixedly provided at the front and rear ends of the upper end of the mounting seat, a fixed seat is fixedly provided at the upper end of the telescopic end of the hydraulic telescopic device, a connecting rod is fixedly provided at the other end of the lower end of the fixed seat, and a placement basket is fixedly provided at the lower end of the connecting rod directly above the quenching pool.

[0012] Preferably, a liquid outlet pipe is fixedly provided at the lower end of the quenching tank, the liquid outlet pipe is communicated with the quenching tank, and a valve is fixedly provided on the outside of the liquid outlet pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model can shield the opening of the quenching tank through the motor and the arc-shaped baffle. When quenching is performed, the casting has been placed in the placement basket. At this time, the motor is turned on to make the output shaft of the motor drive the rotating rod to rotate, and the arc-shaped baffle is driven to rotate in the slide groove by the rotating rod. At the same time, the pulley rotates in the slide groove until the opening of the quenching tank is shielded by the arc-shaped baffle. At this time, the quenching operation is performed to provide protection for the operator. When the quenching is completed, the motor is turned on again to make the motor drive the arc-shaped baffle to rotate again until the opening of the quenching tank is opened, thereby preventing the quenching liquid from splashing out of the quenching tank during the quenching process.

[0015] 2. The utility model can reduce the contact area with the casting through the hydraulic telescopic device and the placement basket. Before quenching, the quenching liquid is poured into the quenching pool. At this time, multiple castings are placed in the placement basket together with a certain distance between the castings. Then the hydraulic telescopic device is turned on to shrink the telescopic end of the hydraulic telescopic device. The contraction of the telescopic end of the hydraulic telescopic device drives the placement basket and the casting to move downward until the casting is immersed in the quenching liquid. At the same time, the mesh placement basket can make the quenching liquid flow into the placement basket, so that the quenching liquid is in full contact with the casting, avoiding excessive contact and shielding area between the fixing device and the casting, thereby improving the quenching effect of the casting.

[0016] 3. The utility model can prevent the quenching liquid from overflowing after the casting is placed in the quenching tank through the overflow tank and the drain pipe. When quenching is performed, the placement basket containing the casting is moved to the quenching tank. Since the casting and the placement basket occupy the internal space of the quenching tank, the liquid level of part of the quenching liquid will rise until the quenching liquid moves to the overflow tank and flows into the overflow tank. The quenching liquid in the overflow tank is discharged from the quenching tank through the drain pipe and collected in a centralized manner, thereby preventing the quenching liquid from directly overflowing and flowing to the lower end of the quenching tank, thereby ensuring the cleanliness of the quenching environment.
