[0002] Quenching is a heat treatment process that heats aluminum alloys or steel to above the critical temperature, keeps it warm for a period of time to make it fully or partially austenitized, and then rapidly cools it at a cooling rate greater than the critical cooling rate to transform it into martensite (or bainite). Quenching is the most critical step in the heat treatment process, which ultimately determines the final quality and grade of the quenched parts. The quenching heat treatment process must be transferred from the quenching furnace to the cooling tank / quenching medium within the specified maximum transfer time. Therefore, the material frame / cage is designed to achieve rapid transfer, and the material frame can quench a large amount of aluminum alloy at the same time, which has high production efficiency. The existing cage is composed of a side and a bottom surface, and the side and bottom surfaces are both set in a grid shape so that the aluminum alloy or steel in the cage can be fully and evenly heated and cooled during quenching.

[0003] The defects of the prior art are: first, the grid of the load-bearing bottom wall of the cage is too large and is not suitable for quenching smaller aluminum alloy workpieces; second, the cage is only provided with one layer, and the space utilization rate is low; and the aluminum alloy workpieces or steels cannot be stacked during quenching to prevent deformation, thereby reducing production efficiency; third, aluminum alloy workpieces or steels of different volumes or sizes need to be cooled at different cooling rates after quenching heating to ensure the quality of each aluminum alloy workpiece or steel, and the single-layer design of the cage is not easy to classify and cool.

DETAILED DESCRIPTION

[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise specified, “plurality” means more than two; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, etc., indicating directions or positional relationships, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0026] like Figure 1-2 As shown, an embodiment of an aluminum alloy quenching cage includes a bottom frame 1, four support columns 2 fixedly connected to the bottom frame 1, a top frame 3 fixedly connected to the support columns 2, and a bottom support portion 4 fixedly arranged in the bottom frame 1; the bottom support portion 4 is a grid-shaped, and the bottom support portion 4 includes a plurality of staggered cross beams 401 and longitudinal beams 402, and the bottom support portion 4 is detachably provided with a partition beam 5; a loading plate 6 is detachably provided between the bottom frame 1 and the top frame 3.

[0027] By providing a detachable partition beam 5, aluminum alloy workpieces of different volumes can be quenched at the same time; the partition beam 5 is provided along the diagonal of the grid of the bottom support portion 4, and a single grid may be provided with one partition beam 5 or two partition beams may be cross-arranged.

[0028] By setting a detachable loading plate 6, optionally, the loading plate 6 is multi-layered, so that the cage has a multi-layer structure and can accommodate more aluminum alloy workpieces at the same time. Optionally, the grid size of the loading plate 6 can be set to a variety of different specifications, and then the aluminum alloy workpieces of different volumes can be placed in layers according to the grid size of the loading plate 6, so as to make full use of the space of the quenching cage and improve the quenching production process. At the same time, the detachable structural design makes it convenient for the aluminum alloy workpieces to complete the heating and heat preservation process. After that, each layer of the loading plate 6 can be independently separated from the cage body and placed in different cooling tanks according to production needs or standards, and cooled with different quenching media, so as to obtain aluminum alloy workpieces with different properties.

[0029] The carrier plate 6 is disposed between the bottom frame 1 and the top frame 3 and in the space enclosed by the four support columns 2 . The surface of the carrier plate 6 abutting against the aluminum alloy workpiece is parallel to the surface of the bottom support 4 abutting against the aluminum alloy workpiece.

[0030] Optionally, the partition beams 5 are arranged diagonally in the grid, or the partition beams 5 are arranged between two adjacent transverse beams 401 or two adjacent longitudinal beams 402 in a single grid.

[0031] In another preferred embodiment, the bottom frame 1 is enclosed by a C-shaped profile, and the cross beam 401 and the longitudinal beam 402 are C-shaped profiles; the notch direction of the bottom frame 1, the cross beam 401 and the longitudinal beam 402 is perpendicular to the length direction of the support column 2.

[0032] like Figure 1-3 As shown, the notch of the C-shaped profile is set laterally, the C-shaped profile has a stable structure, and has many cross-connections, which is convenient for welding and fixing; when the cage enters the quenching medium for cooling, the part of the aluminum alloy workpiece that contacts the C-shaped profile is blocked and is not easy to contact with the cooling quenching medium, which affects the cooling rate of the aluminum alloy workpiece. The wall thickness of the part of the C-shaped profile that contacts the aluminum alloy workpiece is relatively small, and the effect on the cooling rate of the aluminum alloy workpiece is small; and the cooling quenching medium can be cooled faster through the self-guiding function of the C-shaped structure, which improves the cooling rate of the aluminum alloy workpiece compared to solid profiles.

[0033] In another preferred embodiment, the bottom frame 1 is enclosed by a C-shaped profile, the cross beam 401 and the longitudinal beam 402 are I-shaped profiles, and the notch direction of the bottom frame 1, the cross beam 401 and the longitudinal beam 402 is perpendicular to the length direction of the support column 2.

[0034] like Figure 1-3As shown, optionally, the bottom frame 1 is an I-shaped profile. With the design of the I-shaped profile, there are many intersections between the bottom frame 1, the cross beam 401 and the longitudinal beam 402, and the structure is more stable.

[0035] In another preferred embodiment, reinforcing ribs 7 are provided in the angles formed between the cross beams 401, the longitudinal beams 402 and the bottom frame 1; limiting grooves 8 are provided between the two reinforcing ribs 7, or limiting grooves 8 are formed between the reinforcing ribs 7 and the cross beams 401 and / or the longitudinal beams 402; the partition beam 5 is a telescopic structure, and the two ends of the partition beam 5 are respectively clamped in the two opposite limiting grooves 8 at two oblique angles in the grid of the bottom support part 4.

[0036] like Figure 1 , Figure 3 As shown, optionally, a plurality of reinforcing ribs 7 may be provided. In addition to the reinforcing ribs 7 provided in the angles formed between the cross beam 401 , the longitudinal beam 402 and the bottom frame 1 , the reinforcing ribs 7 may also be provided on the opposite longitudinal beams 402 and / or cross beams 401 .

[0037] In this embodiment, the partition beam 5 is diagonally arranged in a single grid, and the angle formed by the cross beam 401, the longitudinal beam 402 and the bottom frame 1 is arranged at the angle; when the cross beam 401, the longitudinal beam 402 and the bottom frame 1 are C-shaped profiles, the C-shaped profile itself has a groove structure, which can limit the single partition beam 5, and reinforcing ribs 7 are added in the groove of the C-shaped profile to limit more than two partition beams 5; if the angle enclosed by the C-shaped profile is formed by two bottom surfaces away from the direction of its notch, more than two reinforcing ribs 7 can be arranged at the angle.

[0038] The partition beam is a telescopic structure. In this embodiment, the partition beam includes two partition beam sections, one of which is provided with a through hole, and the other is provided with a waist hole. The through hole and the waist hole are fixed by bolts, and the through hole moves in the waist hole to adjust the length of the partition beam, so that the partition beam is conveniently clamped in the limiting groove 8. Optionally, the two partition beam sections are sleeved structures, or overlapped.

[0039] In another preferred embodiment, the partition beam 5 includes a base plate 501, on which a protrusion 502 is arranged; the length direction of the base plate 501 is arranged along the extension direction of two adjacent diagonal corners of the base plate 4 and / or the carrier plate 6, and the base plate 501 is pressed on the base plate 4 and / or the carrier plate 6, and the protrusion 502 is arranged to cooperate with the grid concave-convex of the base plate 4 and / or the carrier plate 6.

[0040] like Figure 2 , Figure 4 As shown in the figure, the raised portion 502 of the partition beam 5 cooperates with the grid protrusions and depressions to limit the partition beam 5.

[0041] When the substrate 501 is pressed on only one grid, the raised portion 502 matches the pressed grid concavoconvexly. When the substrate 501 is pressed on more than two grids, the raised portion 502 can match the concavoconvexly of one or more grids; preferably, the raised portion 502 is arranged at both ends of the substrate 501, and the raised portions 502 at both ends of the substrate 501 match the concavoconvex of the grid to achieve the limit of the partition beam, which has a simple structure and saves materials.

[0042] Compared with the detachable partition beam 5 of a single grid, the design of the partition beam 5 is simple in structure and convenient for loading and unloading. Optionally, the partition beam 5 is provided on the bottom support 4 or the upper part of the carrier plate 6; the grid is larger where the partition beam 5 is not provided, and a larger aluminum alloy workpiece is placed; the grid is smaller where the partition beam 5 is provided, and a smaller aluminum alloy workpiece is placed; it is suitable for quenching aluminum alloy workpieces of different volumes at the same time.

[0043] In another preferred embodiment, the carrier plate 6 is in a grid shape, and the support column 2 is provided with a limiting member 9 along its length direction, and the limiting member 9 is connected to the carrier plate 6 .

[0044] There are multiple groups of limit members 9 arranged along the length direction of the support column 2 , and the carrier plate 6 can be connected to any group of limit members 9 , and different groups of limit members 9 limit the carrier plate 6 to be located at different heights.

[0045] like Figure 1-2 As shown, the limiter 9 can be a reinforcing rib arranged on the support column 2, and the four corners of the carrier plate 6 are pressed on the limiter 9; the limiter 9 can also be a component that is clamped into the grid of the carrier plate 6 to support and limit the position of the carrier plate 6.

[0046] The loading plate 6 may also be provided with a lifting ring, so that the loading plate 6 can be locked and then lowered horizontally and vertically to be separated from the cage body; or the loading plate 6 can be locked to form a grid structure of beams and columns to separate the loading plate 6 and the cage body.

[0047] In another preferred embodiment, a connecting member 10 is provided on the top frame 3, and the connecting member 10 is connected to the lifting assembly 11 through a pin shaft.

[0048] like Figure 1-2 As shown, in this embodiment, the lifting assembly 11 is a hanging beam, and there are at least two hanging beams, and the two hanging beams are arranged on the top frame 3 and the two hanging beams are arranged opposite to each other.

[0049] In another preferred embodiment, side blocks 12 are provided between the support columns 2, and the side blocks 12 are in a grid shape.

[0050] like Figure 1-2 As shown, a side stop 12 is provided to prevent the aluminum alloy workpiece from escaping from the cage from the side.

[0051] The material carrying plate 6 is detachably connected to the supporting column 2 , or detachably connected to the side stop 12 .

[0052] The working process of the aluminum alloy cage includes the following steps:

[0053] Heating and heat preservation: According to the size of the bottom support grid, the aluminum alloy workpieces are divided into two categories according to their volume. According to the number of aluminum alloy workpieces whose volume is smaller than the grid size, inclined beams are set in the grid, and the aluminum alloy workpieces are placed in intervals;

[0054] Connect the carrier plate to the limiter and place the aluminum alloy workpiece on the carrier plate; place the cage in the quenching furnace for heating and heat preservation for a period of time before taking it out;

[0055] Cooling: The lifting mechanism is connected to the lifting assembly and drives the entire cage into the quenching medium for cooling; or the lifting mechanism is first connected to the loading plate and drives the loading plate into the quenching medium A for cooling, and then connected to the cage body and drives the cage body into the quenching medium B for cooling, thereby realizing layered cooling and achieving the difference in the performance of the aluminum alloy.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
