Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to metal processing technical field especially relates to a tool for cleaning dehydration high quality appearance piece. BACKGROUND
[0002] In the production process of stainless steel fasteners, it is usually necessary to carry out electroplating treatment to enhance its corrosion resistance and aesthetics. The cleaning, passivation, dehydration and drying before electroplating are key steps, which directly affect the appearance quality of the final product. For appearance parts, surface finish and integrity are particularly important, and any surface defects (such as scratches, pits, etc.) will affect the appearance quality of the product, and thus affect the acceptance of customers.
[0003] In the cleaning, passivation, dehydration and drying process, a drum device is usually used for treatment. For fasteners with small outer diameter (such as below 3mm), since the self-weight is light, the rolling in the drum will not cause obvious damage to the surface, so the drum can be used normally for treatment, and the appearance quality of the product will not be affected. However, for fasteners with large outer diameter (such as above 3mm), since the self-weight is large, the rolling in the drum will cause the head of the product to collide with each other, and thus scratches and surface injuries will be caused, forming point-like pits. These surface defects will seriously affect the appearance quality of the product, especially under the requirement of appearance parts, customers cannot accept such defects. SUMMARY
[0004] To solve the problems in the above background art, the utility model provides a tool for cleaning and dehydrating high-quality appearance parts, which can be used to complete the passivation cleaning process of appearance parts, and the appearance parts do not collide with each other during dehydration, thus ensuring product quality.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0024] Example:
[0025] This embodiment describes a fixture for cleaning and dehydrating to achieve a high-quality appearance.
[0026] like Figure 1 As shown, Figure 1 This is a structural schematic diagram of a fixture for cleaning and dehydrating high-quality exterior parts according to this utility model. The fixture includes a fixture housing 1, several partitions 2, and several mesh plates 3. The partitions 2 and mesh plates 3 are placed inside the fixture housing 1 in the following order: partition 2, mesh plate 3, partition 2. The exterior parts are placed on the mesh plates. By layering partitions and mesh plates, and then covering them with another partition, the exterior parts are prevented from falling off or being thrown out during the cleaning process.
[0027] To facilitate the installation of the partitions and mesh plates inside the fixture housing, a central shaft 4 is fixedly designed on the fixture housing 1. This central shaft guides the installation position of the partitions and mesh plates. Corresponding to the central shaft 4, central holes 11 are respectively provided on the partitions 2 and mesh plates 3. The partitions and mesh plates are installed at the center position of the fixture housing along the central shaft, and the central shaft also serves as a limiting force.
[0028] Furthermore, to ensure the secure installation of the partitions and mesh plates, a pin hole 5 is provided at the upper end of the central shaft 4. After the partitions and mesh plates are placed in the fixture housing, a fixing pin 6 passes through the pin hole 5 to secure the partitions and mesh plates inside the fixture housing 1. At this point, regardless of whether the fixture is rotated up, down, left, or right, the partitions, mesh plates, and exterior parts will not fall off.
[0029] like Figure 2 As shown, Figure 2 This is a schematic diagram of the grid plate in a fixture used for cleaning and dehydrating high-quality exterior parts. The grid plate 3 has several exterior part placement compartments 7, into which the exterior parts are placed. Multiple exterior parts can be processed simultaneously using cleaning and other procedures, and each exterior part is independently located in its placement compartment, preventing collisions.
[0030] The spatial dimensions of each compartment for placing exterior components within the grid plate are designed according to the dimensions of the exterior components. Similarly, the size of the fixture's outer casing can also be designed to be compatible with the size of the dewatering machine.
[0031] In order to prevent liquid from remaining in the fixture during the cleaning and passivation process, and to ensure that there are no dead corners during the subsequent dehydration and drying, this utility model provides several dehydration holes 8 on the partition plate 2, and several through holes 9 on the bottom of the fixture shell.
[0032] Example 2
[0033] This embodiment, based on embodiment 1, further demonstrates the arrangement of the partition plate and the grid plate in the fixture housing.
[0034] Combined with appendix Figure 1 , 2 As shown, Figure 1 This is a schematic diagram of the structure of a fixture for cleaning and dehydrating high-quality exterior parts according to the present invention. Figure 2 This is a schematic diagram of the structure of a grid plate in a fixture for cleaning and dehydrating high-quality appearance parts. A fixture for cleaning and dehydrating high-quality appearance parts includes a fixture housing 1, several partitions 2, and several grid plates 3. The partitions 2 and grid plates 3 are placed in the fixture housing 1 in the following order: partition 2, grid plate 3, partition 2.
[0035] In this embodiment, the setup is as follows: a partition is placed inside the fixture housing, a mesh plate is placed on top of it, the above operation is repeated twice, and finally, the top mesh plate is covered with a partition. That is, three layers of mesh plates and four layers of partitions are placed.
[0036] Several appearance component placement grids 7 are provided on the grid plate 3, allowing each appearance component to be placed independently.
[0037] Each layer of partition 2 and mesh plate 3 is also provided with a center hole 11 corresponding to the central shaft 4 on the fixture housing 1. After all the layers are placed, they are fixed by using fixing pins 5 passing through the pin holes 5 at the upper end of the central shaft 4. In the electroplating passivation production line, the fixture is manually held up and down and left and right for cleaning and passivation. The dehydration holes 8 on the partition 2 and the through holes 9 at the bottom of the fixture housing 1 facilitate the passage of liquid through the interior of the fixture and through the various exterior parts.
[0038] like Figure 3 As shown, Figure 3 This diagram illustrates the interaction between a fixture for cleaning and dehydrating high-quality exterior parts and a dehydrator. After cleaning and passivation are completed, the fixture is placed in the designated dehydrator 10 for dehydration. The diameter and height of the fixture's outer shell are matched to the internal diameter and holding height of the dehydrator. The dehydrator is an existing device; in this embodiment, a Qixin D400 dehydrator is used as an example, with an inner drum size of 400mm, an inner drum height of 260mm, a horsepower of 1HP, and a power of 1.8KW. After dehydration, the parts are placed in an oven for drying (80℃ / 1 hour). After these procedures are completed, the fixture is removed, the fixing pin 6 is taken out, and the partition 2 is removed. Then, the cleaned and passivated exterior parts are removed one by one with tweezers and placed in a designated packaging tray.
[0039] As can be seen from the above introduction, the fixture for cleaning and dehydrating high-quality appearance parts of this utility model, by setting several placement grids on the grid plate and using it in conjunction with the partition, not only solves the problem that the appearance parts would collide with each other and affect the appearance quality due to the original processing method, but also the fixture can complete various processes such as cleaning and passivation of appearance parts, as well as dehydration and drying. Because dehydration holes are set on the partition and through holes are set on the appearance of the fixture, the dehydration and drying efficiency is improved, and no water stains are left on the product surface.
[0040] This utility model fixture has a simple structure, is easy to process and assemble, and can be designed according to different sizes and models of dehydrators, thus having good applicability.
[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
