Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel for electroplating which improves the assembling and maintenance of the barrel used for electroplating.

[0002]

2. Description of the Related Art Conventionally, as a barrel for this type of electroplating, rotating plates b are provided at both ends of a hexagonal cylinder a as shown in FIGS. A lid c for loading and unloading the product to be plated is provided on the surface, and the product to be plated is plated while rotating the barrel.

However, the hexagonal cylinder a is formed by bending a single plate having innumerable through holes and forming an opening on one side circumferential surface, and then rotating with both ends of the hexagonal cylinder a. Since the plate b and the plate b are fixed by fusion, the fusion work requires a lot of skill and is very troublesome, and since a single plate is used, a part of the peripheral surface portion may be damaged. For example, the entire hexagonal cylinder a must be replaced, which has the drawback of extremely poor maintainability.

Further, since the hexagonal cylinder a is made of a single plate, the peripheral surface portions are likely to be curved and deformed as the cylinder length and the outer diameter increase. Since they have to be fused, the number of work steps is increased and workability is further deteriorated.

With respect to the lid c, a mounting portion f for forming a slender elongated hole e is provided along the side edge of the opening in the hexagonal cylinder a, and the upper surface of the lid c for closing the opening is provided. Since the hook g to be inserted into the long hole e is provided, it takes time and trouble to operate the hook g one by one, and there is a disadvantage that the plated object is very troublesome to put in and take out.
