Description

Technical Field

[0001] The utility model relates to a storage device in forging processing, in particular to a combined material basket used for boxing and transporting precision forgings. Background Art

[0002] After the forging process is completed, the forgings need to be packed. The packing method affects the quality of the finished forgings and the production efficiency. The currently commonly used packing method is to manually put the forgings into the material box. Although it is simple and easy to operate, when using a forklift to transfer the material box between the various processes, the forgings are prone to shaking and colliding with each other due to the bumps in the movement of the forklift and the stacked contact of the forgings in the material box. For ordinary forgings, since their subsequent machining allowance is large, even if slight bumps and damages occur, they can be handled through subsequent processing and will not affect the final product quality. This kind of bump and damage can be accepted to a certain extent. However, for precision forgings, such as precision forgings that have already forged a tooth shape, refer to Figure 1 A precision forging with teeth has the following problems when it is packed by manual packing method:

[0003] (1) Compared with ordinary forgings, the structure of precision forgings is more complex. Due to the different placement strength, angle and position of each operator, precision forgings are more likely to be bumped and damaged when entering the material box;

[0004] (2) The subsequent processing allowance of complex structures such as tooth-shaped parts in precision forgings is extremely small, and it is difficult to remove the bumped parts through subsequent processing like ordinary forgings. Once the complex structure of the forging is damaged during packaging and transportation, it will directly increase the scrap rate in the subsequent process and seriously affect the qualified rate of the final product;

[0005] (3) The diameters and thicknesses of various parts of precision forgings are often not uniform. When the material boxes are placed manually, the forgings are stacked on top of each other, making it impossible to visually and accurately count the production quantity manually. The subsequent statistics are cumbersome and the counting speed is extremely slow, which will affect the subsequent production arrangements.

[0006] Therefore, it is necessary to improve the existing packaging method of precision forgings to overcome the above problems.

[0007] In order to meet the requirements of mounting and hanging of quenched parts of different sizes, a Chinese patent with announcement number (CN204281832U) discloses a flexible grid-type heat treatment basket. The main body of the basket is a cubic structure. The bottom of the basket is a grid structure surrounded by stainless steel bars. Four groups of support beams vertically connected to the bottom of the basket are arranged at the four corners of the bottom of the basket. The sides of the basket are provided with several layers of cross beams parallel to the bottom of the basket and connected to the support beams. The cross beams on each side are composed of two steel bars. The steel bars on the adjacent sides are arranged in a cross-staggered structure. A cross bar is provided between the cross beams on the opposite sides of the same layer. The outer diameter of the cross bar matches the outer diameter of the steel bar. The two ends of the cross bar are provided with threads and plugs from the outside to the inside. The end of the cross bar is placed between the two steel bars of the cross bar. The basket adopts a cross bar restraint and adjustable method. The mounted parts are restrained by restraining the position of the cross bar, avoiding the use of a large amount of aluminum wire to fix the parts.

[0008] In order to accurately position parts, a Chinese patent with a publication number of (CN205856522U) discloses an accurately positioned quenching basket, wherein a lifting lug is installed on the upper part of the basket, the basket is connected to the quenching heating furnace through the lifting lug, and a plurality of layers of tray positioning pins are arranged on the inner wall of the basket, each layer has at least three tray positioning pins, the tray is assembled with the basket through the tray positioning pins, the bowl-shaped die forgings are placed in a row on the tray, and the bowl-shaped die forgings are positioned vertically on the tray by product positioning pins placed on both sides thereof.

[0009] The above two solutions are mainly used for parts quenching, and have complex structures and high costs. They are not suitable for solving the collision problems of precision forgings during packaging and transportation. Utility Model Content

DETAILED DESCRIPTION

[0056] The specific technical solutions in the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] See also Figure 2-9 A combined material basket comprises a grid structure, a material basket body 1 welded from Φ10 steel bars, four hanging ears 2 welded on the material basket body 1 and formed by bending Φ10 steel bars, a baffle 3 welded from Φ6 steel bars arranged inside the material basket body 1, and a partition panel 4 welded from Φ10 steel bars fixed inside the material basket body 1; Definition: the direction in which the opening of the material basket body 1 faces is upward;
