[0031] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment provides a material basket device for heat treatment workpieces, such as Figure 1 As shown, the frame 20 includes a base frame 10 and a frame 20 placed thereon, wherein the base frame 10 is constructed as a grid structure, including a bottom frame 11 and a plurality of frame beams 12 placed in the bottom frame 11, and the lower end surface of the bottom frame 11 is constructed as a flat surface, which is convenient for being placed on the transfer frame of the heat treatment furnace and convenient for being stacked and stacked with other material baskets; and all the frame beams 12 are arranged crosswise with each other, which can improve the placement strength and supporting force of the bottom frame 11. The frame 20 is constructed with a vertical frame 21, a horizontal beam 22, a support block 24 placed on the horizontal beam 22, and a guide column 23 placed on the top of the vertical frame 21, and the vertical frame 21 and the horizontal beam 22 are surrounded by an open material area for placing workpieces. The frame 20 can stack other material baskets carrying workpieces through the support block 24 and the guide column 23, and can be suspended or supported for transportation at the same time, so as to transport the workpiece to the processing table or other target area of ​​the heat treatment furnace.

[0033] like Figure 3 As shown, the bottom frame 11 is a rectangular structure or a square structure, which is convenient for adapting to the transfer furnace table on the heat treatment furnace. In this embodiment, the base frame 10 and the frame 20 are both made of welded steel. Because the workpiece is an alloy metal part, such as aluminum alloy, its density is small and its weight is relatively light, and the strength requirements can be met by using steel. Moreover, steel is easy to obtain and easy to process; at the same time, its appearance and shape and position tolerances are guaranteed; using steel to weld the base frame 10 and the frame 20 can not only save a lot of manufacturing costs, but also steel of different materials (such as nickel-chromium steel, carbon steel) can also be adjusted based on the requirements of different processes and different temperature conditions, which is highly versatile and safe and reliable.

[0034] Among them, the size of the bottom frame 11 and the vertical frame 21 is wider than that of other frame beams. The several frame beams 12 arranged in the bottom frame 11 are all vertically cross-connected to each other. They are steel reinforced rib beams, which are arranged vertically and horizontally. The bottom of the basket is provided with multiple steel reinforcement ribs in both vertical and horizontal directions, which are connected to the bottom cross beams and are crisscrossed. Notches are opened at the vertical intersections of adjacent frame beams 12, which are embedded in each other when connected, and then welded into an integrated structure. This type of structure can better limit the displacement and deformation in the two cross directions, resist thermal deformation, and has strong impact load resistance. It can not only improve the strength and reliability of the overall structure of the base frame 10, but also extend the service life of the basket.

[0035] like Figure 3 As shown, within the allowable strength range of the base frame 10, ventilation holes 13 are arranged on the frame beams 12, that is, at least on each frame beam 12 in the same direction, neatly arranged ventilation holes 13 for absorbing thermal expansion are provided. Of course, neatly arranged ventilation holes 13 for absorbing thermal expansion can also be provided on the frame beams 12 in all different directions, but the figure is omitted. The ventilation holes 13 can be long holes, round holes, square holes or polygonal holes of other cross-sections according to different working conditions. The ventilation holes 13 are all configured to penetrate the thickness of the frame beams 12. Such ventilation holes 13 can also reduce the overall weight of the basket, and can resist thermal deformation and impact while absorbing thermal expansion.

[0036] like Figure 2 As shown, in order to improve the convenience of transporting the basket, a pair of parallel fork hole beams 14 are also configured in the bottom frame 11 of the bottom frame 10. The fork hole beams 14 are evenly distributed in the bottom frame 11 and are used to cooperate with a forklift to transport the basket. Preferably, the fork hole beams 14 can be arranged in parallel or crosswise with the frame beam 12 configured with the vent hole 13. The fork hole beams 14 can be arranged along the length direction of the frame 20 or along the width direction of the frame 20, which is not specifically limited here.

[0037] like Figure 4 As shown, the frame 20 includes a plurality of vertical frames 21 arranged on the base frame 10 and a crossbeam 22 connected to the upper end surface of the vertical frames 21. The vertical frames 21 and the crossbeam 22 are arranged to form a material area. The workpiece is placed in the material area and can be arranged along the width direction of the base frame 10 or along the length direction of the base frame 10. The arrangement can be adjusted based on actual conditions. Among them, the support block 24 is constructed on the crossbeam 22, and its upper end surface is a flat surface, which is convenient for the base frame 10 of another material basket stacked on the frame 20 to be placed flat.

[0038] The number of all guide posts 23 is the same as the number of the vertical frames 21, that is, a guide post 23 is welded on the top of each vertical frame 21, and the guide posts 23 are all arranged on the top of the vertical frame 21, mainly used for guiding the bottom frame 10 of the upper material basket when stacking, and a limit groove is also arranged on it, and the structure of the limit groove is a common structure in the field, and the drawings are omitted. Preferably, the guide post 23 is configured as a circular cone, a square cone, a triangular cone, or a trapezoidal cone structure, and of course a sleeve structure can also be selected.

[0039] The main body of the frame 20 is mainly composed of four corner uprights 21 and cross beams 22 connected to each other, and also includes a plurality of sets of hanging frames 25 and a plurality of support beams 24 used to act as reinforcing ribs, which are arranged on the aligned cross beams in the frame 20. The uprights 21 are cylindrical bodies of circular or rectangular structure, which are connected to the cross beams 22 to form an integrated fixed structure of the frame 20. The support block 24 is arranged on the upper end surface of the cross beam 22, and the width of the support block 24 is greater than the width of the cross beam 22, and is mainly used to support the bottom frame 11 of the upper bottom frame 10 so that it can be stably stacked on the material basket below.

[0040] The structure of the guide column 23 is adaptable to various working conditions. During the production process, if the material baskets need to be stacked in multiple layers, the stacking robot can accurately stack and stack the multiple layers of material baskets under the guidance of the guide. The combined effect of the guide column 23 and the support block 24 can make the stacked positions of the multiple layers of material baskets more stable and the force more reasonable.

[0041] Furthermore, the hanging bracket 25 and the support block 24 are arranged around the frame 20, and the hanging bracket 25 is constructed with a hanging groove of an inverted trapezoidal structure, and is staggered with the support block 24. A plurality of support beams 26 are used as support reinforcement ribs, and their upper and lower ends are respectively connected to the cross beam 22 and the bottom frame 11 in the bottom frame 11, and they are obliquely or vertically symmetrically arranged on both sides of the hanging bracket 25. In order to further improve the strength of the fixing of the support beam 26, a fixing block connected to the support beam 26 is further arranged on the upper end surface of the bottom frame 11 in the bottom frame 10, and the fixing block is horizontally arranged on the bottom frame 11 and is welded together with the lower end surfaces of all the support beams 26.

[0042] The side of the frame 20 of the material basket uses an inclined or vertically arranged support beam 26, which serves as a reinforcement structure and can well absorb thermal deformation caused by thermal expansion or uneven temperature. In addition, the setting of the hanging frame 25 can cooperate with the hanging frame 25 under the action of the stacking machine to achieve automatic stacking. The support beams 26 on all sides are reserved with hanging frames 25, that is, symmetrically arranged support beams 26 are provided on both sides of each hanging frame 25. This structure is not only suitable for various loading and unloading methods such as overhead cranes and forklifts, but also the entire material basket can also adapt to various transportation methods such as forklift fork foot transportation, AGV fork foot transportation, AGV vehicle latent bottom support transportation, and lifting.

[0043] The material basket device for heat treatment workpieces designed by the present application has a simple and reasonable structure, can realize the smooth entry of workpieces into the furnace, has a compact and lightweight structure, can adapt to a variety of automatic machinery, runs smoothly and has strong anti-deformation ability, is easy to operate, and is strong and durable. The material basket device is not only resistant to thermal stress and large impact load, but also adapts to the operation of automated production furnaces, is stable, strong and durable; it also cooperates well with material transmission machinery, can adapt to a variety of loading and unloading methods, is easy to operate and has low manufacturing cost, and provides stable, safe and effective guarantees for automated production.

[0044] The above detailed description of the embodiments of the present application is only a preferred embodiment of the present application and cannot be considered to limit the scope of implementation of the present application. All equivalent changes and improvements made within the scope of the present application should still fall within the scope of the patent coverage of the present application.
