Abstract

PURPOSE:To enhance working efficiency in electrolytic treatment, by a method wherein a current is passed through a plate jig and a coil spring having parts to be treated placed thereon from a power source and further passed through the parts to be treated from said spring to facilitate the attachment and the detachment of said parts to be treated with respect to the plate jig. CONSTITUTION:Plural set members 3 comprising an insulating material are arranged on a plate jig 14 comprising a conductor and a coil spring 15 is placed around the member 3 in a free state. A worker may inserted parts 1 to be treated merely into the member 3 to place the same on the spring 15 and, because a current passing state is directly established by this operation, electrolytic treatment is applied to the treating range 1a of the parts 1 immersed in an electrolyte 11. In this case, a current is flowed to a negative voltage terminal 5a through an electrode 10, the electrolyte 11, the parts 1, the spring 15, the plate jig 14 and a carrier 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of supplying electricity to a part to be treated in electrolytic treatment such as electrolytic degreasing, and more particularly to a method of supplying electricity to a part to be treated which facilitates attachment and removal of the part to be treated from a root jig.

Conventionally, electrolytic treatments include electrolytic degreasing, electrolytic pickling, electrolytic cleaning, etc. As an example, as shown in FIG. A carrier 4 made of a *&sf1 conductor is connected to a set member 3 made of ffc seal rubber, for example, to a negative voltage terminal 5a (sometimes a positive voltage terminal) of a power source 5 with a conductor 6, and the carrier 4 and the part to be processed l are connected. It was designed to be connected with a conducting wire 8 having a current-carrying clip 7 attached to its tip. A method has been adopted in which the part to be processed 1 is placed on the root jig 2, and each time the part to be processed l is held and connected with the energizing clips 7, and the part to be processed l is energized from the carrier 4. Also, carbon electricity*XO
is connected to, for example, a positive voltage terminal 5b (sometimes a negative voltage terminal) of a power source 5 by an N1 conductor 12 immersed in an electrolytic solution 11, and constitutes an anode, and the part to be processed 1 also has a processing range Ig. is immersed below the surface of the electrolytic solution 11 and constitutes an n1 cathode.

However, according to the conventional energizing method, in addition to the work of placing a large number of parts 1 to be processed on the plate jig 2, it is necessary to attach the energizing clip 7 to each part 1 to be processed. In addition, since it is necessary to remove the current-carrying clip 7 from all the parts 1 to be processed, a large number of man-hours are required and the production efficiency is low. In addition, since a large number of conductive wires 8 and current-carrying clips 7 are required, there is a drawback that it takes time and effort to deal with disconnections and clean up after the wires. For this reason, the cost of electrolytic treatment has been high.

The present invention has been made to eliminate the drawbacks of the prior art described above.
(The purpose of this is to provide an energizing system that allows installation to the plate jig and electrical connection to be completed at the same time by simply placing the part to be processed on the conductive coil wire.) Another object of the present invention is to provide a method, and to facilitate the work of attaching and removing parts to be treated from a root jig in electrolytic treatment, thereby significantly reducing the number of man-hours and improving work efficiency. By eliminating conductor wires and current clips from the plate jig, it is easier to work as there is no need to pay attention to disconnections or clean up after the process, ensuring that all parts to be processed are energized, and reducing the cost of electrolytic treatment. The aim is to reduce

In short, the present invention insulates a part to be processed from a root jig made of a conductive material with a set member made of an insulating material, and a coil spring made of a conductive material is loosely fitted around the set member so as to be directly above the root jig. , the part to be processed is placed on the coil spring, the root jig and the coil spring are energized from a power source, and the part to be processed is further energized from the coil spring. be.

The present invention will be explained below based on embodiments shown in the drawings. The jig 14 according to the present invention is made of a conductive material, and the plate jig and the part to be processed 1 are insulated by a set member 3 made of seal rubber.

The carrier 4 and the plate jig 14 are electrically connected f1.
The carrier 4 is connected by a conductor 6 to a negative voltage terminal 5a (also sometimes a positive voltage terminal) of a power source 5, for example. The electrode 10 is connected to, for example, a positive voltage terminal 5b of the power source 5 by a conducting wire 12.
(sometimes a negative voltage terminal). A coil spring 15 made of a conductive material, for example stainless steel, is loosely fitted around the set member 3 and placed on the root jig 14. The free length of the coil spring 15 is longer than the height h from the top of the root jig 14 of the set member 3, and is bent by the force of the part to be processed f1. That is, the step part 1 of the part to be processed
The coil lock 15, the root jig 14, and the part to be processed 1 are pressed together with moderate pressure until the part b contacts the upper surface 3a of the set member 3.
Electricity is applied to the part to be processed 1 via the root jig 14 and the coil spring 15. Then, the precision of the processing range 1a of the part to be processed 1 immersed in the electrolytic solution 1 is maintained as sufficiently high as in the conventional example.

Since the part to be processed 1'+ is placed on the coil spring 15, it is possible to absorb differences in the lengths of the parts to be processed.

The present invention is constructed as shown above, and its function will be explained below. I will clarify. Normally, VC on root jig 14
, a large number of setting members 3 are arranged around which a coil spring 15 is rested in a free state, and the worker inserts the part to be processed 1 into the setting member 3 and attaches the coil spring to the coil spring. 15, f'LIr1 is placed on top of the coil spring 15 and the set member 3, which makes the installation very easy. The removal work 46 is much easier and faster because it only needs to be rubbed off, and since the conducting wire 8 and the red electric clip 7 are not present on the mounting jig 14 as in the conventional example, the work becomes even easier. Keep your work environment tidy.

Since the present invention is configured and operates as described above, the attachment to the plate jig and the electrical connection can be completed at the same time by simply placing the part to be processed on the conductive coil wire. The present invention provides an energization method that facilitates attachment and removal of parts to be processed in electrolytic treatment to plate jigs, greatly reduces man-hours, and improves work efficiency. The first person attends. In addition, since the current-carrying conductor and current-carrying clip can be removed from directly above the cutting edge, there is no need to be careful about disconnection of the conductor or clean up afterwards, making the work easier and ensuring that all parts to be processed are energized. In addition, the cost of electrolytic treatment can be reduced.
