Abstract
Description
Technical Field
[0001] This invention relates to a charging box for a vacuum annealing furnace, which is particularly suitable for vacuum annealing heat treatment of small parts made of electromagnetic pure iron, soft magnetic alloys or elastic alloys. Background Technology
[0002] Vacuum annealing is a common heat treatment process that involves holding parts at a certain temperature and vacuum level for a period of time, followed by slow cooling in the furnace. Its purpose is to maintain a certain level of gloss and shine on the parts during annealing.
[0003] Because electromagnetic pure iron, soft magnetic alloy, or elastic alloy parts have strict quality requirements, they must not be subjected to impacts or bumps, and cannot be directly touched by hand, as these impacts or bumps can affect the magnetic properties or other mechanical properties of the product. Therefore, how to avoid impacts or bumps on electromagnetic pure iron, soft magnetic alloy, or elastic alloy parts during vacuum annealing is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a charging box for a vacuum annealing furnace.
[0005] This invention is achieved through the following technical solution: A charging box for a vacuum annealing furnace includes a stainless steel box body and several stainless steel drawers. Each side wall of the stainless steel box body is provided with multiple through holes. The several stainless steel drawers are slidably disposed in the stainless steel box body. Each stainless steel drawer is provided with multiple parts placement compartments, and each side wall of the parts placement compartment is provided with multiple through holes.
[0006] The stainless steel box is rectangular in shape, and one side of the stainless steel box is open.
[0007] The stainless steel enclosure includes an enclosure body, inside which are provided several support plates. The support plates are parallel to the bottom plate of the enclosure body, and multiple through holes are arranged in a rectangular array on each side wall of the enclosure body and on the support plates.
[0008] On the bottom plate and support plate of the cabinet body, two slide rails are arranged side by side, and a limiting plate is provided on one end of the slide rail near the opening of the stainless steel cabinet. The bottom of the stainless steel drawer is provided with a slider that is slidably connected to the two slide rails.
[0009] The parts compartments inside the stainless steel drawer are arranged in a rectangular array.
[0010] Each side wall of the part placement grid is provided with multiple through holes arranged in a rectangular array.
[0011] The stainless steel drawer is equipped with a handle.
[0012] The beneficial effects of this invention are as follows: during the vacuum annealing process, the parts are separated by the parts placement compartments in the stainless steel drawers, which can effectively prevent the parts from bumping or colliding with each other. In addition, the multiple stainless steel drawers are arranged in layers to prevent the parts from being stacked, which is beneficial to ensuring the magnetic properties and other mechanical properties of electromagnetic pure iron, soft magnetic alloy or elastic alloy parts.

[0015] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.
[0016] like Figures 1 to 3 As shown, the present invention provides a charging box for a vacuum annealing furnace, comprising a stainless steel box body 1 and a plurality of stainless steel drawers 2. Each side wall of the stainless steel box body 1 is provided with a plurality of through holes 3. The plurality of stainless steel drawers 2 are slidably disposed inside the stainless steel box body 1. Each stainless steel drawer 2 is provided with a plurality of parts placement compartments 21, and each side wall of the parts placement compartments 21 is provided with a plurality of through holes 3. In use, multiple stainless steel drawers 2 are arranged in layers from bottom to top. The shape and size of the parts placement compartment 21 are adapted to the shape and size of the parts to be vacuum annealed. For example, if the part is spherical, the parts placement compartment 21 is hemispherical; if the part is cuboid, the parts placement compartment 21 is also cuboid. The parts and parts placement compartment 21 are fitted with a small gap. The depth of the parts placement compartment 21 is about 2 / 3 of the length of the part. This ensures that the parts can be taken out and put in normally while ensuring the stability of the parts in the parts placement compartment 21. It also prevents large-scale movement of the parts in the parts placement compartment 21, thereby preventing violent impacts or collisions between the parts and the side walls of the parts placement compartment 21 during the process of pulling out the stainless steel drawer 2.
[0017] After pulling out the stainless steel drawer 2 from the stainless steel housing 1, place the cleaned parts to be vacuum annealed one by one into the corresponding parts placement compartment 21. Then, push the stainless steel drawer 2 back into the stainless steel housing 1. Next, place the loading box into the vacuum annealing furnace to anneal the parts. After annealing, pull out the stainless steel drawer 2 from the stainless steel housing 1 and remove the parts. During the vacuum annealing process, the parts are separated by the parts placement compartment 21 in the stainless steel drawer 2, which effectively prevents the parts from bumping or colliding with each other. Furthermore, the layered arrangement of multiple stainless steel drawers 2 prevents the parts from stacking, which helps to protect the magnetic properties and other mechanical properties of electromagnetic pure iron, soft magnetic alloy, or elastic alloy parts.
[0018] Using a charging bin to place parts for vacuum annealing avoids inconsistencies in the vacuum annealing quality caused by differences in the furnace loading positions of each operator, thus reducing the number of times parts need to be reworked.
[0019] The stainless steel box 1 is rectangular in shape, with an opening on one side. The size of the loading box is determined based on the effective heating zone size of the vacuum annealing furnace to prevent the parts from exceeding the effective heating zone when the loading box containing the parts is placed into the vacuum annealing furnace, and also to maximize the use of the internal space of the vacuum annealing furnace.
[0020] The stainless steel box 1 includes a box body 11, and multiple support plates 12 are provided inside the box body 11. The support plates 12 are parallel to the bottom plate of the box body 11, and multiple through holes 3 are arranged in a rectangular array on each side wall of the box body 11 and on the support plates 12.
[0021] On the bottom plate of the cabinet body 11 and the support plate 12, two slide rails 13 are arranged side by side. A limiting plate 14 is provided on one end of the slide rail 13 near the opening of the stainless steel cabinet body 1. The bottom of the stainless steel drawer 2 is provided with a slider that is slidably connected to the two slide rails 13. The limiting plate 14 limits the slider to prevent the stainless steel drawer 2 from disengaging from the slide rail 13.
[0022] The parts compartments 21 inside the stainless steel drawer 2 are arranged in a rectangular array. This facilitates the operator in taking and placing parts, and also makes it easy for the operator to count the parts.
[0023] The parts placement compartment 21 has multiple through holes 3 arranged in a rectangular array on each side wall. The multiple through holes 3 on each side wall of the main body 11, the support plate 12, and the parts placement compartment 21 facilitate the circulation of hot gas within the loading box when the vacuum annealing furnace heats the loading box and the parts placed inside. This ensures that the temperature inside the loading box remains consistent with the furnace temperature of the vacuum annealing furnace, and also helps maintain consistent gas pressure inside the loading box with that inside the vacuum annealing furnace.
[0024] The stainless steel drawer 2 is equipped with a handle. This allows for easy pushing and pulling of the stainless steel drawer 2 using the handle.
