A plating pretreatment apparatus for a multi-cylinder block includes a plurality of cylinders that performs a plating pretreatment of a cylinder inner wall surface of each of the cylinders using an electrode disposed so as to oppose to the cylinder inner wall surface by sealing one end of the cylinder inner wall surface and introducing a treatment liquid to the cylinder inner wall surface. In such plating pretreatment apparatus, at least one of a power supply device that supplies electricity to the cylinder block and the electrode and a liquid feed pump that feeds the treatment liquid into a gap between the cylinder inner wall surface and the electrode is provided for each of the cylinders.

Plating pretreatment apparatus and method for multi-cylinder block

A cylinder block plate processing apparatus in which one end side of an inner peripheral surface of a cylinder of a cylinder block is sealed to circulate a process liquid to perform pre-plating or plating processing of the cylinder inner peripheral surface. The apparatus includes: an apparatus body having a workpiece mount table on which the cylinder block is placed; a workpiece holding tool that is provided on the workpiece mount table so as to be vertically movable; an electrode support member including an electrode cylinder mounted to the apparatus body; a processing solution supply member that supplies a processing solution to the electrode support member; an electrode operated by the electrode cylinder; a sealing jig provided to one end of the electrode; a driving mechanism that drives the sealing jig; and a control circuit that controls operations of the processing solution supply member and the driving mechanism.

Cylinder block plate processing apparatus and sealing mechanism of the same

The present invention provides an apparatus for plating pretreatment of a cylinder block that includes an electrode performing a plating pretreatment of the cylinder inner wall surface. A gap flow channel communicates with an in-electrode flow channel at a position closest to a seal jig, the gap flow channel being adapted to introduce a treatment liquid to the cylinder inner wall surface, the in-electrode flow channel being adapted to receive the treatment liquid having passed through a communicating hole. The present invention is provided a method for pretreating before plating a cylinder block including disposing an electrode to face the cylinder inner wall surface so as to form a gap flow channel, and introducing a treatment liquid to the gap flow channel thereby flowing through the treatment liquid toward a seal jig and then into an in-electrode flow channel through a communicating hole.

Plating pretreatment apparatus and method for cylinder block

A plating method for pre-plating or plating a cylinder inner peripheral surface to be treated of a cylinder block by introducing treatment liquid to the cylinder inner peripheral surface by using a plating apparatus provided with a sealing jig having a sealing member and an electrode to which the seal jig is mounted includes the steps, which are performed successively: sealing the cylinder inner peripheral surface by bringing the sealing jig into contact with the cylinder inner peripheral surface; introducing the treatment liquid to the cylinder inner peripheral surface; and treating the cylinder inner peripheral surface by applying predetermined charge to the electrode of the plating apparatus and the cylinder block to thereby perform pre-plating or plating process in a state that a liquid to be treated fills a space including the cylinder inner peripheral surface. In the method, the treatment liquid introducing step is performed after confirmation of sealing by the sealing step.

Plating method

A sealing jig comes into contact with a cylinder inner peripheral surface as a surface to be processed of a cylinder block and seals the cylinder inner peripheral surface in introducing treatment liquid to the cylinder inner peripheral surface. The sealing jig includes: a sealing member made of an expandable material and having a ring-buoy shape; a lower plate for supporting a lower side of the sealing member; and a seal base disposed so as to face the lower plate and to support an upper side of the sealing member. The sealing member is regulated by the lower plate and the seal base and expanded only in a radial direction to come into contact with the cylinder inner peripheral surface when air is introduced inward.

Sealing jig and plating treatment apparatus

A conveyor for guiding and conveying a plurality of sheet-shaped thin plates in rows arranged side by side to a welding position at which ends of the adjacent thin plates are butted and welded to each other, includes a plurality of conveying paths, which are adjacent to each other, having different conveying surfaces which are placed on a same horizontal plane, and a guide unit disposed between the adjacent two conveying paths for guiding the thin plates on one of the conveying paths with respect to another one thereof toward the welding position. Each of the conveying paths is composed of a plurality conveying rollers, and the guide unit includes guide rollers each having a guide surface for guiding the thin plate on the one of the conveying paths in a state that the thin plate on the one conveying path is partially depressed with respect to the another one of the conveying path.
