Problems solved by technology

Furthermore, since the amount of oil supplied to the sliding surface further increases when the sliding surface becomes uneven, a vicious cycle of further abnormal discharge occurs.
[0006] In addition, there is a problem that the oil supplied to the sliding surface scatters and drips into the coating tank of the coating device, resulting in deterioration of the coating solution.
Moreover, there is a problem that oil flows between the above-mentioned current collecting member and other members, and the current is difficult to flow due to the oil on the sliding surface of the above-mentioned current collecting member, and a higher voltage such as 9V is required.
Not only that, but there is also a problem of heating up to a higher temperature than usual, such as 120°C
In addition, in the case of using a graphite current collecting member, there is a problem that dust is generated due to abrasion due to rotation and current collection.

Embodiment 1

[0042] As a cylinder plating device, in addition to figure 1 Except for the illustrated structure, an apparatus having basically the same structure as a conventional cylinder plating apparatus was used. A current collecting member 12 is used at the base end of the mandrel of the collet cone. As the current collecting member 12, SPB-7590100 manufactured by Oiles Industry Co., Ltd. was used. As the plating solution, a chromium plating solution having a chromic acid concentration of 250 g / L and a sulfuric acid concentration of 2.5 g / L was used.

[0043] Use a cylindrical base material with an aluminum core of 800mm in circumference and 1250mm in surface length as the cylinder to be treated. Clamp both ends of the cylinder to be treated and install it in the plating tank so that the chrome plating solution overflows to be treated. The tank is completely submerged. The rotational speed of the cylinder to be processed is set to 100 rpm, the temperature of the plating solution is ...

Embodiment 2

[0051] use figure 1 The device of the configuration shown was used as the plating device. A current collecting member 12 is used at the base end of the mandrel of the collet cone. As the current collecting member 12, SPB-7590100 manufactured by Oiles Industry Co., Ltd. was used. A copper plating solution comprising 200 g / L of copper sulfate, 100 g / L of sulfuric acid, and 100 mg / L of chloride ions was used as the plating solution.

[0052] Use a cylindrical base material with a circumference of 800mm and a surface length of 1250mm as the cylinder to be treated. Clamp both ends of the cylinder to be treated and install it in the plating tank so that the copper plating solution overflows to be treated. The tank is completely submerged. The rotational speed of the cylinder to be processed was set at 250rpm, the temperature of the plating solution was 45°C, the current density was 30A / dm2 (current 3000A), and the voltage was 6V. Plating treatment was carried out for 10 minutes ...

Abstract

Provided is a current collecting member for a cylinder body plating apparatus, which is used at the base end of the spindle of a chuck cone, thereby making it possible to plate a sliding surface without oiling and to prevent efficiently high-temperature heat generation at low voltage without generating abnormal discharge. Provided also is a plating apparatus. The current collecting member is attached to the base end of a chuck cone of a cylinder body plating apparatus in which both ends of a cylinder body are gripped with a chuck cone and the cylinder body is rotated to perform plating, the current collecting member including a cylindrical base material and a plurality of lubricating regions made of oil-impregnated carbon or oil-impregnated carbon-containing resin provided on the sliding surface of the cylindrical base material in a scattered manner.

Description

technical field [0001] The present invention relates to a current collecting member for a cylinder plating device and a plating device using the same, and in particular to a current collecting member for a cylinder plating device which is particularly suitable for use at the base end of a mandrel of a collet cone and a device using the same Plating device. Background technique [0002] Conventionally, when a processed object such as a cylinder block is subjected to a plating process with a plating apparatus, a plating apparatus for cylinders described in Patent Document 1 is known. Further, as a fully automatic gravure plate-making processing system including the cylinder plating device described in Patent Document 1, there is the fully automatic gravure plate-making processing system described in Patent Document 2. [0003] In the cylinder plating device described in Patent Document 1, when power is supplied to the cylinder or when power is supplied from the cylinder side ...
