Description

Technical Field

[0001] This utility model belongs to the field of dip coating tooling technology, and relates to a dip coating tooling for single basket coating machine processing of large bolts. Background Technology

[0002] Currently, Dacromet coating mainly employs two methods: dip-coating-centrifugation and spraying. Dip-coating-centrifugation is typically used for processing large batches of small standard parts (such as screws, nuts, and washers). The workpieces are placed in a basket and immersed in a coating bath. After being removed, excess coating is removed by high-speed centrifugation, and then the workpieces are cured in an oven. This method has significant advantages such as high production efficiency, uniform coating without dead angles, high material utilization, and low cost. However, its application is limited by the size and weight of the workpieces. For larger bolts (around M16-M24), due to their large individual weight and size, forced centrifugation can cause the workpieces to collide and damage each other. Friction between parts during unloading can also damage the coating. Therefore, large bolts have long been excluded from dip-coating processes. Spraying is currently the most commonly used method for processing large workpieces such as large bolts. Although spraying overcomes the limitations of workpiece size, it suffers from disadvantages such as unstable coating uniformity and quality, low material utilization, high cost, environmental pollution and health hazards, and relatively low production efficiency. Therefore, an innovative technical solution is needed to overcome the limitations of existing dip coating equipment, enabling large bolts to undergo Dacromet treatment using a dip-coating-centrifugal process, thereby achieving excellent coating quality while significantly reducing production costs and improving processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dip-coating fixture for single-basket coating of large bolts, thus solving the problem that large bolts cannot enjoy the high-quality, low-cost, and high-efficiency processing advantages of dip coating.

[0004] The objective of this utility model can be achieved through the following technical solutions: A dip-coating fixture for single-basket coating of large bolts is characterized by comprising a large bottom ring and a small bottom ring located within the large bottom ring, the large bottom ring and the small bottom ring being connected by reinforcing ribs, a large top ring and a small top ring being connected to the upper ends of the large bottom ring and the small bottom ring by a column, a plurality of first insert rings being evenly arranged on the inner side of the large top ring, and a plurality of second insert rings corresponding to the first insert rings being evenly arranged on the outer side of the small top ring, a modular placement bracket being detachably inserted into the first insert rings and the second insert rings, and a plurality of supporting rings being evenly arranged on both sides of the modular placement bracket.

[0005] In the above-mentioned dip coating fixture for processing large bolts in a single basket coating machine, the modular placement bracket is a steel bar bent at both ends.

[0006] In the above-mentioned dip coating fixture for single basket coating machine processing of large bolts, the modular placement bracket and the supporting ring are connected by welding.

[0007] In the above-mentioned dip coating fixture for processing large bolts using a single-basket coating machine, the number of reinforcing ribs is six.

[0008] In the above-mentioned dip coating fixture for processing large bolts using a single-basket coating machine, there are six columns on both the large bottom ring and the small bottom ring.

[0009] Compared with the prior art, the present invention has the following advantages: This fixture design meets the requirements of the dip-coating-centrifugation process for larger bolts. It can systematically secure bolts ranging from M16 to M24, preventing slippage and damage to the coating during the dip-coating and centrifugation process. The dip-coating method results in a uniform coating without dead angles, providing excellent corrosion resistance. There is no excess paint waste, leading to high material utilization. Production efficiency is higher than spraying. Only manual placement of bolts onto the fixture significantly reduces labor costs and intensity. The modular design ensures high material utilization and convenient fixture management. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] like Figures 1 to 3 As shown, A dip-coating fixture for processing large bolts using a single-basket coating machine is characterized by comprising a large bottom ring 2 and a small bottom ring located within the large bottom ring 2. The large bottom ring 2 and the small bottom ring are connected by reinforcing ribs. The upper ends of the large bottom ring 2 and the small bottom ring are connected to a large top ring 4 and a small top ring 5 via a column 3. A plurality of first insert rings 6 are evenly arranged on the inner side of the large top ring 4, and a plurality of second insert rings 7 corresponding to the first insert rings 6 are evenly arranged on the outer side of the small top ring 5. A modular placement bracket 8 is detachably inserted into the first insert rings 6 and the second insert rings 7. A plurality of supporting rings 9 are evenly arranged on both sides of the modular placement bracket 8.

[0014] In this embodiment, the supporting ring 9 is divided into multiple sizes according to the size of the bolts to be processed, thus forming modular placement brackets 8 of different specifications. During processing, the bolts to be processed are placed on the modular placement brackets 8 of appropriate size on the supporting ring 9, and then their two ends are inserted into the first insertion ring 6 and the second insertion ring 7. The entire fixture is placed in a single-frame coating machine for dip coating and centrifugation. This fixture design meets the needs of the dip coating-centrifugation process for larger bolts. Using this fixture, bolts of about M16 to M24 size can be fixed in an orderly manner. During the dip coating and centrifugation process, the bolts will not slip or bump, and the coating will not be damaged. The dip coating method results in a uniform coating without dead corners and good anti-corrosion effect. There is no excess paint waste, and the material utilization rate is high. The production efficiency is higher than that of the spraying method. Only manual placement of bolts on the fixture is required, which significantly reduces labor costs and labor intensity. The modular design results in high utilization of fixture materials and convenient fixture management.
