Description

  The present invention relates to a protector for a material to be plated, and in particular, attaches to a portion that needs to be protected in a pre-plating process in a detachable manner, and performs the plating process on the material to be plated as it is. Regarding possible protective equipment.

  Many industrial products are subjected to plating treatments such as electroplating, electroless plating, vapor deposition plating, and chemical conversion treatment in order to impart decorativeness, rust prevention, wear resistance, electrical conductivity, and the like. Among these industrial products that handle fluids, if the seal surface, which is a joint part with other members, is damaged, the proper airtightness will be impaired and fluid leakage will occur. It will be disposed of as a defective product. In this way, for industrial products that are particularly required to prevent damage to specific parts in the material to be plated, in order to reduce the defective product rate and increase product productivity, some protective equipment is attached to the parts. However, at present, no suitable protective equipment is provided, and the actual condition is that the plating material is plated without wearing the protective equipment. For this reason, it is necessary to carefully perform various operations from the production of the material to be plated to the shipment of the product, and it is difficult to improve the productivity, and it is possible to prevent the occurrence of some defective products. This is not possible, and there is a limit to reducing the defective product rate.

  In addition, as a protector for the tube end after finishing the plating process, a protective device having a cap-like appearance formed of rubber or a synthetic resin and having its inner surface in close contact with the tube end at the time of mounting is conventionally used. It is known (see Patent Documents 1, 2, and 3). Since these protectors make the inner surface of the protector formed like a cap closely contact the tube end, it is possible to protect the tube end from the action of external force, intrusion of dust, and the like.

The plating solution circulation hole is formed between the two linear members to be formed. To.

If a protective device is attached around the protective surface after the material to be plated is manufactured, the impact force is protected even if another material or jig collides in the process after the protective device is attached. Since it is relieved by the tool, damage to the protective surface can be prevented. In addition, a plating solution circulation hole that penetrates from the outer surface to the inner surface of the protector is formed, and a gap through which the plating solution can flow is formed between the material to be plated and the inner surface of the protector when mounted around the protective surface. Then, the plating solution, cleaning solution and dry air can be brought into contact with the material to be plated through these plating solution flow holes and voids as necessary, so that the required thin film or film is applied to the entire material to be plated including the protective surface. It can be formed properly. The plating treatment includes electroplating, electroless plating, and chemical conversion treatment. Moreover, although it has not been confirmed, it is estimated that the present invention can also be applied to a material to be plated on which vapor deposition such as physical vapor deposition or chemical vapor deposition is performed. And the protector of this structure is applicable to the to-be-plated material by which the protective surface was formed in the edge part of a tubular body.

Further, in order to solve the above technical problem , the present invention provides a plated object in which a ring-shaped connector portion is formed at an end portion of a tubular body, and first and second protective surfaces are formed on both front and back surfaces of the connector portion. A protective device to be attached to the material, having a plating solution circulation hole penetrating from the outer surface to the inner surface of the protective device, and when mounted around the protective surface, between the material to be plated and the inner surface of the protective device.

In addition, a flow path for the plating solution is formed between the inner surface of the elastic deformation portion 12 and the top surface of the ring-shaped protrusion R, and between the protrusion 14 and the top surface of the ring-shaped protrusion R. Further, the inner width of the locking claw 13 and the abutting protrusion 15 (the abutting protrusion 15 is not shown) is about 0.1 mm to 1.0 mm larger than the outer diameter of the tube P, A flow path for the plating solution is also formed between the tip of the locking claw 13 and the tube P and between the tip of the abutting protrusion 15 and the tube P. Further, the distance between the lower surface of the locking claw 13 and the top surface of the abutting protrusion 15 is about 0.1 mm to 1.0 mm larger than the thickness of the annular protrusion R. A flow path for the plating solution is also formed between R and the top surface of the butting protrusion 15 and the ring-shaped protrusion R. Note that the inner diameter of the ring-shaped portion 11 is the same as the inner width of the elastically deformable portion 12 and the protruding piece 14, and a sufficiently large plating solution flow passage is formed between the outer surface of the tube body P. Reference numeral 17 shown in FIG. 5 indicates a plating solution flow passage formed between the pipe body P and the engaging portion 1.

  As apparent from FIGS. 1 and 5, the locking claw 13 is formed in a substantially mountain shape so that the protector 1 </ b> A can be easily attached to and detached from the tubular body P.

Can be made. Therefore, by attaching the protector 1A to the material to be plated W1 before the start of the plating process, the seal surface S is prevented from being damaged due to the collision with other materials to be plated or jigs. Since the required thin film and film can be appropriately formed on the entire material to be plated W1 including the surface S, it is possible to greatly improve the defective product rate of the plated product while improving the efficiency of the plating process. Productivity of plated products can be increased. Moreover, since the protective equipment 1A is integrally formed with fluororesin, 11 nylon, 12 nylon, etc. excellent in heat resistance and chemical resistance, it can be used repeatedly and is economical. Furthermore, since it can be appropriately attached to and detached from the material to be plated W1, the sealing surface S is completely protected by leaving it attached to the material to be plated W1 until the product is shipped or connected to another fluid coupling. Can be made.
