As shown in FIGS. 1 to 6, the permanent magnet-attached accessory according to the present invention is a part carried on the body for the purpose of relieving pain in the human body using the magnetic field of the permanent magnet, and is manufactured by adhering the permanent magnet to various shapes. By manufacturing it, it is possible for users to use it efficiently.

The ornaments are not limited thereto, and may be provided in various forms such as rings, bracelets, necklaces, earrings, pendants, brooches, chains, piercings, charms, necklaces, or bracelets.

As shown in FIG. 1, the permanent magnet attachment type ornament according to the present invention is largely a mold manufacturing step, an aluminum composite material preparation step, a shearing step, a pressing step, a forging step, a barrel polishing step, an anodizing step, a post-processing step, a permanent magnet manufacturing step Step, including a permanent magnet bonding step, an inspection step and a packaging step. Hereinafter, each individual step will be described in detail.

a) Mold making stage

First, a mold for molding the parts constituting the ornament is manufactured. The components may include pendants, pins, chain components, and the like. It is also possible to engrave certain patterns or rings on the mold.

b) material preparation step

Separately, an aluminum composite is prepared in the form of a linear or plate-shaped accessory for the accessory.

To this end, the aluminum composite is put into a furnace, melted, and the molten solution is put into an extruder and extruded into a wire or plate having a uniform cross-sectional shape.

The aluminum composite is 90.70 to 93.00 wt% of aluminum, 0.30 to 0.60 wt% of silicon, 0.30 to 0.60 wt% of iron, 3.80 to 4.90 wt% of copper, 0.20 to 0.30 wt% of zinc, 0.30 to 0.90 wt% of manganese, 1.20 to 1.80 wt% of magnesium % by weight, and a composition consisting of 0.05 to 0.20% by weight of chromium is melted in a melting furnace at 1,600 to 1,800° C. according to a conventional alloy manufacturing method, hot forged into a wire or plate, and then air-cooled to room temperature It can be prepared.

If the composition of the aluminum composite is out of the above range, there is a problem in that a pain relief function is weak or it is difficult to expect an increased pain relief function with a permanent magnet.

c) shearing step

In the shearing step, the aluminum composite material is cut to a predetermined size using a hydraulic cutting machine or the like.

d) pressing step

The cut aluminum composite material is placed in a press mold such as punch pressing and pressed to shape each part of the ornament. A certain pattern or ring may be formed on the surface or the back surface of the composite material, and a groove for accommodating the permanent magnet is formed on one side of the part, and the groove is preferably larger than the diameter of the permanent magnet.

e) forging step

The pressed material is heated and pressed through the forging (fractionation) process to separate the unit parts engraved with decorative patterns one by one.

f) Barrel grinding step

The separated unit parts are barrel polished to smooth corners and surface roughness, and burrs are removed. Abrasive grains can be used for barrel polishing to make the surface roughness smooth and precise.

g) anodizing step

Parts with polished surfaces are anodized and oxidized. It may be more preferable to oxidize by anodizing with a known sulfuric acid method. As such, in the anodizing step, an oxide film is formed by eroding the surface to artificially create an oxide film that is naturally generated on the surface of the part, so that the surface of the accessory can have a uniform resistance to corrosion or external environment.

h) post-treatment step

The anodized parts are then post-processed as necessary.

The post-processing may include a process of color coating using a resin such as epoxy, a process of assembling a mardipin of a bracelet, a process of engraving a pattern using a laser, or a process of assembling a chain and a pendant of a necklace. .

i) Permanent Magnet Manufacturing Stage

Separately, the permanent magnet material is mixed and dried to prepare a constant shape (eg, disk shape, cylindrical shape) of a size to be accommodated in the groove formed in the accessory part.

The permanent magnet is in direct or indirect contact with the human body and generates a magnetic field to relieve muscle pain.

In the treatment method by magnetic force, when magnetic force is applied to the human body, a new magnetic induction is generated, an induced current is generated in the blood, and it becomes a physical catalyst to exchange kinetic energy, and ions ( Ion) increases, resulting in a change in autonomic nerve activity. In addition, the supply of oxygen and nutrients to the tissues is activated by the blood, and at the same time, carbon dioxide gas or wastes are excreted out of the body, and peripheral nerve circulation is improved. It has been clinically proven that magnetic force is harmless to the human body and relieves pain while acting to relieve headaches, stiff shoulders, and back pain in each part of the human body.

The permanent magnet is a ferrite-based metal, Φ3.2 x 1.3(t) mm, may preferably have a weight of 0.3g, a magnet density of 80 to 800 Gauss ± 30%, and strontium ferrite powder (Cas no. 12023-91-5) 85-95 wt%, chlorinated polyethylene (Cas no. 64754-90-1) 5-15 wt% and calcium stearate, calcium stearate (Cas no. 1592-23-0) It may be more preferably composed of 0 to 1% by weight.

If the magnet density is out of the above range, there is a fear that the pain relief effect may be weak or side effects may occur.

j) Permanent magnet bonding step

The manufactured permanent magnet is adhered to one side of the accessory part with an adhesive. A groove for accommodating the permanent magnet is formed on one side of the part, and it may be preferable that the groove is larger than the diameter of the permanent magnet.

The adhesive is acrylate copolymer (Cas No. 25085-02-3) 53-56 wt%, ethyl acetate (Cas no. 141-78-6) 24-26 wt%, vinyl acetate monomer (Cas no. 108-) 05-4) 13 to 17% by weight and toluene (Cas No. 108-88-3) 3 to 6% by weight may be preferable.

The adhesive is preferably made of a component that performs a function that does not cause detachment of attachments and skin troubles even when carrying accessories for a long period of time.

k) Inspection Step

This is a step to check whether there is any abnormality in the finished magnet-attached accessory product, check the appearance and damage of the finished product, check whether the physical characteristics comply with the regulations, and prepare for packaging.

l) Packing step

The inspected product is packaged in a certain unit using a conventional method. In addition, it may be desirable to put a certain amount of the product in an aluminum pack or nylon paper, a plywood pack or a PET resin container and seal it.

Figure 2 is a manufacturing process diagram of the permanent magnet attachment type ornaments of the present invention, which may be more preferable mainly for the manufacture of bracelets or necklaces.

The basic processes are the same as described above, and the necklace or bracelet may consist of a pendant (medal) or main display part (exposed surface) and a chain part in which certain parts are repeated, and the pendant or main display part can be manufactured by the process described in FIG. In addition, the chain part may be manufactured by fastening the repeating unit parts with pins or fastening (by rotational coupling, etc.) so that certain repeated parts are alternately fastened. Similarly, the pendant and the chain can be fastened using the formed ring.
