Description

Technical Field

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

[0002] Castings, as an important product form in the field of metal processing, are widely used in many industries such as machinery, automobiles, ships, aerospace, etc. The performance of castings, especially their hardness, wear resistance, fatigue resistance and other indicators, are directly related to their service life and safety; in order to improve these properties of castings, quenching technology is widely used in the post-processing process of castings.

[0003] Quenching is a heat treatment process that rapidly cools a metal material heated to above a critical temperature to transform its internal structure, thereby obtaining the required hardness and wear resistance. For castings, quenching can not only increase the hardness of the matrix structure, but also refine the grains and enhance the fatigue resistance of the casting.

[0004] In order to improve the uniformity of quenching heating, the castings are usually placed in a heating furnace for heating after forming. At the same time, for the efficiency of quenching, the quenching is combined with the assembly line to make the quenching automatic and continuous. However, due to the setting of the assembly line, there are no heating devices on both sides of the assembly line, which can easily affect the heating uniformity of the castings and needs to be improved.

[0055] It can be seen from the present embodiment that by setting the rotating assembly 3, the casting can be rotated after it moves to the heating channel 5 of the machine body 1 under the action of the electric hanging rail assembly 4, thereby ensuring uniform heating of all surfaces of the casting, avoiding uneven heating of the casting surfaces on both sides of the moving direction of the assembly line, and improving the quenching effect.

[0056] Embodiment 2:

[0057] This embodiment provides a casting quenching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The rotating assembly 3 includes:

[0058] The rotating shaft 30 is vertically mounted on the hanger 20 and connected to the bearing of the hanger 20;

[0059] The driving unit 31 is installed on the hanger 20 and is used to drive the rotating shaft 30 to rotate.

[0060] It can be seen from this embodiment that the rotating shaft 30 is connected to the bearing of the hanger 20, so that the rotating shaft 30 can not only rotate but also play a supporting role, thereby simplifying the structure.

[0061] Embodiment 3:

[0062] This embodiment provides a casting quenching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features. The driving unit 31 includes:

[0070] A stopper 314 is mounted on the hanger 20 and is used for meshing the synchronous belt 313 with the driven gear 312;

[0071] The number of the stoppers 314 is the number of the driven gears 312 minus 2. Specifically, the surface of the synchronous belt 313 is not provided with the stoppers 314 except for the driven gears 312 at both ends of the synchronous belt 313.

[0072] Meanwhile, the stopper 314 and the hanger 20 may be connected by bolts.

[0080] It can be seen from the present embodiment that by providing a connection block 21 with a round hole 22 and using an S-shaped hook 23, the convenience of hanging and removing the casting on the connection block 21 is improved.

[0081] Embodiment 6:

[0082] This embodiment provides a casting quenching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0083] The surface of the body 1 is provided with two covers 6 which are symmetrically arranged along the heating channel 5, and the two covers 6 are slidably connected to both sides of the body 1;

[0084] Slide rails 7 are installed on both sides of the body 1 at both ends of the heating channel 5;

[0091] In addition, the slidingly connected cover bodies 6 improve the convenience and quenching efficiency during assembly line quenching, that is, under the action of the electric hanging rail assembly 4, when the casting enters, the two cover bodies 6 slide away from each other and open, and after the casting enters, the two cover bodies 6 slide close to each other; and the opening of the arc groove 10 improves the fit between the two cover bodies 6 after they are closed to each other, further avoiding heat loss.

[0092] Embodiment 7:

[0093] This embodiment provides a casting quenching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including:

[0094] A cooling assembly 11 is installed on the side of the machine body 1 and is located at one end of the heating channel 5 and is used to cool the casting after quenching;

[0095] Wherein, the cooling assembly 11 includes a cooling channel 110, and the electric hanging rail assembly 4 passes through the cooling channel 110;

[0096] Meanwhile, the heating channel 5 and the cooling channel 110 are arranged along the same direction.

[0097] It can be seen from this embodiment that by arranging the cooling channel 110 arranged in the same direction as the heating channel 5, the electric hanging rail assembly 4 is driven into the cooling channel 110, thereby improving the automation and continuity of quenching.

[0098] Embodiment 8:

[0099] This embodiment provides a casting quenching device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the cooling component 11 also includes:

[0100] A fan 111 is installed on one side of the cooling channel 110 and is used for air cooling of the casting;

[0101] The air hood 112 is installed on the other side of the cooling channel 110 and is used to recover hot air;

[0102] The suction hood 112 is also provided with an induced draft fan for exhausting air, and the induced draft fan and the fan 111 are both existing mature technologies, and their specific structures are not described here in detail.

[0103] It can be seen from this embodiment that by using the fan 111 for air cooling, the wind speed of the fan 111 can be easily controlled. After the casting is quenched and heated and kept warm for a period of time, the wind speed of the fan 111 is relatively low at the beginning, and it is cooled to an appropriate temperature, that is, higher than the room temperature and lower than the critical temperature, to avoid excessive thermal stress. Then, the wind speed of the fan 111 is increased to quickly cool the casting to perform martensite (or bainite) transformation, thereby improving convenience.

[0104] In combination with the rotating assembly 3, the cooling speed of the entire casting surface is increased, and the surface cooling uniformity is good, thereby improving the quenching quality of the casting.

[0105] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
