Description

Technical Field

[0001] The invention relates to the technical field of bushing processing, in particular to a bushing tooling non-stick coating process. Background Art

[0002] Bushings are accessories used outside mechanical parts to achieve sealing, wear protection and other functions. Bushings are more flexible to use and can play many roles. In general, bushings are a type of component that protects equipment. The use of bushings can reduce the wear, vibration and noise of equipment and has an anti-corrosion effect. The use of bushings can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment.

[0003] During the production process, the bushing is generally positioned using jigs and fixtures. The jigs and fixtures will be contaminated by glue during use, and the glue attached to the jigs and fixtures will damage the bushing. Therefore, the glue on the jigs and fixtures needs to be removed. The traditional cleaning methods are as follows:

[0004] The first method is to use the method of incineration to remove glue. After incineration, toxic gases will be produced, polluting the environment, and the fixture will be deformed after incineration, and the service life will be short;

[0005] Type 2: Technical problems of conventional technology: Chemical degumming agents will volatilize, pollute the environment, and the degumming cost is high. After chemical immersion, a large amount of clean water is needed to rinse. After rinsing, the fixture will rust again and needs to be made of stainless steel. However, if stainless steel is used, the cost of tooling and fixture will be relatively high.

[0006] The third type: Technical problems existing in conventional technologies: the strength of plastic materials is low, the jigs need to be relatively large, and they are not resistant to high temperatures. They cannot be debonded after use and need to be scrapped, and the cost of tooling and jigs is very high;

[0007] Therefore, it is difficult to deal with glue pollution, which increases the cost of removing glue pollution. Summary of the invention

[0008] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] The first embodiment of the present invention provides a non-stick coating process for a bushing tool, and the non-stick coating process for a bushing tool comprises the following steps:

[0036] S1. Glue removal: unfold the pallet, use a scraper to scrape off the thicker glue, then evenly apply the agent to the inside of the pallet, and then remove the glue contamination on the surface of the tooling fixture.

[0037] By using a spatula to scrape off the glue, it is easier for the agent to solidify and peel off the glue, thereby improving the efficiency of glue removal.

[0038] S2. Sandblasting: Place the pallet in the sandblasting tooling and use 60# diamond sand to sandblast the surface of the pallet. After treatment, it needs to be cleaned and treated with silane phosphide to remove the glue residue inside the pallet.

[0039] After the glue on the pallet is peeled off, there will still be residue on its surface. Then put the pallet in the sandblasting tool. After the glue residue is removed by 60# diamond abrasive in the sandblasting tool, the surface of the pallet is clean and free of residue.

[0040] S3. One-time spraying: Use Chemours Teflon 420G Teflon coating as the primer to spray the tooling fixtures in the isolation room, and control the coating thickness to 10-20μm.

[0041] Spray Teflon coating on the sandblasted pallet, and adjust the position of the pallet during the spraying process so that the pallet can be fully sprayed with Teflon coating.

[0042] S4. Primary drying: Place the sprayed fixtures in a drying facility for drying. After drying, take out the fixtures and cool them to room temperature.

[0043] S5. Secondary spraying: Use Chemours Teflon 858G Topcoat clear Teflon coating to spray the tooling fixtures in the isolation room. In order to improve durability, the topcoat needs to be sprayed twice and cured twice.

[0044] S6. After spraying, the paint film is cured at 380℃ for 30 minutes and can be used after cooling.

[0045] By applying a special non-stick coating on the tooling jig, the use effect is good, and the problem of the tooling jig being difficult to handle after being contaminated by glue is solved. At the same time, the glue contaminated on the tooling jig is very easy to remove, and online cleaning is achieved. The operation efficiency is high, the number of tooling jigs invested is small, the cost is low, and the use process will not cause any pollution to the environment.
