- Presented in Publication No. 52243.

The present invention aims to finish the production of such wire tools with high precision, and uses glue, resin adhesive, etc., pressure adhesion, temporary plating, and other electrical or magnetic fixing methods on long materials. When making a wire tool for grinding or cutting by temporarily attaching abrasive grains or hard particles to this and fixing it with plating, it is also possible to prevent the adhesion of abrasive grains, etc. by adding abrasive grains in the plating liquid. Composite plating can be performed by mixing and dispersing the material and fixing the abrasive grains at the same time as plating, and plating the material while adjusting the outer diameter of the abrasive grains and hard particles of the temporarily attached long material through a die. Plating is applied by passing through a plating treatment tank, the diameter of the plating coated portion on the surface of the material that moves through the plating treatment layer and comes out is detected, and depending on the inspection result, additional plating or de-plating is controlled. It is characterized in that it passes through a finishing plating treatment tank in which it is subjected to high-precision finishing, and is finally washed and dried for finishing.

The present invention will be explained below with reference to an embodiment of the drawings. In FIG. 1, a long material 1 such as a wire or a band is fed out from a winding frame 2, and the plated portion is wound onto another winding frame 3. The long material 1 moving between the winding frames 2 and 3 is guided through a plurality of processing tanks and processes by a guide, first passing through a degreasing tank 4 and then a cleaning tank 5 as usual. Then, plating pretreatment is performed. 6 is a plating treatment tank, 7 is a plating electrode that is placed close to and opposite to the running long material 1, and the plating liquid is supplied to the electrode 7 from a pump 8.
A jet stream is supplied from a supply nozzle located in the center of the . 9 is a plating power source that passes an intermittent pulsed current between the electrode 7 and the long material 1, and the plating state can be easily controlled by controlling the pulse width (τon), pause width (τoff), number of repetitions, etc. However, it is of course possible to use a steady DC power source, an AC power source, a pulsating current power source, or the like. 10 detects the temperature of the liquid in the liquid tank 6 and controls the power source 9. For example, when the liquid temperature rises, the temperature is controlled such that the pause width (τoff) of the energization pulse is increased so that constant plating can be performed. Reference numeral 11 denotes a storage tank that constantly controls the ion concentration of the plating liquid supplied to the plating tank by the pump 8, and a control circuit 12 is provided that detects the current conduction resistance in the liquid in the plating tank and uses this as a signal.
This controls ion control by controlling electricity supply and electrolysis of the stored liquid.

FIG. 2 is an enlarged detailed view of one embodiment of the plating electrode 7. The electrode 7 is provided with dies 7b at both ends, through which the elongated material 1 is inserted into the electrode and moves through. Supply hole 7 inside
The plating liquid supplied by the pump 8 flows out from a. The jet stream is a high-speed jet stream by pressurizing the liquid, and is controlled so that the liquid pressure or flow rate is constant.
Then, it is ejected from the die 7b into the plating treatment tank 6 and flows back into the storage tank 11 (not shown).

Therefore, both the dice 7b are integrated with the electrode 7,
Alternatively, the abrasive grains and hard particles which are provided separately and temporarily attached by the die 7b on the inlet side and which are extra protruded from the elongated material 1 are plated, so that the abrasive grains and hard particles are uniformly formed. A plating coating layer containing hard particles is formed, and the die 7b on the other exit side
By further handling the material, the abrasive grains and hard particles that floated during plating are removed, and by pressing, the outer diameter is made uniform and the inspection accuracy of the next step of the plating coating inspection is ensured. It is possible to maintain the precision of the tool manufactured at the same time, and to obtain a wire tool with high precision by adding or removing plating at a later stage as a finishing condition. 13 passes through a plating electrode, that is, a plating processing section, is handled by a die 7b, and a portion of a long material 1 is moved and treated to form a plating film on which abrasive grains and hard particles are adhered to the outer periphery. This is a plating coating inspection device installed on a section. Specifically, as shown in Fig. 3, there is a dogleg-shaped fixed guide 13.
A, the long material 1 is held in between and the movable element is pressed, and the displacement of the movable element is detected by a detection device 13 such as a differential transformer.
It is possible to use a device that detects the wire by using a wire, which can be installed on a cross axis, or a large number of devices can be installed radially around the wire axis as shown in Fig. 4. Although not shown, a non-contact detection device using ultrasonic waves may also be used.

Reference numeral 14 denotes a plating electrode that performs additional plating or de-plating on the long material 1 that has passed through the inspection device 13, 15 an inspection device that performs the inspection again, 16 a plating electrode, and a pump for both plating electrodes 14 and 16. 8 is also used to supply plating liquid in a jet stream. Inspection signals from the inspection devices 13 and 15 are applied to the control device 17, thereby controlling the energization switches 18 and 19 for additional plating and deplating. Although the plating tank 6 is configured to be used as one tank until the final plating process is performed, each plating tank may be configured to be separate and independent. Reference numeral 20 denotes a drive motor for controlling the traveling of the long material 1, which is controlled by the control device 17, and finishes plating when the portion of the long material 1 that has just passed through the inspection device 13 and 15 passes through the plating electrodes 14 and 16. The drive is controlled so that the processing is performed. The drive monitor 20 can easily perform position control, speed control, etc. by performing pulse drive using, for example, a stepping motor such as an electric motor whose rotation angle is controlled to be constant or a stepping motor such as a hydraulic device. 21 is a water washing device, 22 is a drying device, and the long material finished through the above process is wound onto the winding frame 3.

In the plating process, the long material 1 is degreased, the cleaning tank 4 is
5, the abrasive grains and hard particles forming the grinding blade are adhered and fixed, and then tackified and then plated. Such a long material 1 is plated with an electrode 7.
The plating liquid is controlled to have a constant jet pressure or jet flow rate, and the plating process is performed while flowing at high speed. Further, the jet liquid is ion-controlled and the liquid temperature is controlled. When the liquid temperature rises, pulse control of the energizing power source 9 is carried out so that a plating film of a constant density and a constant thickness is always formed in a constant state. or,
At this time, the traveling speed of the long material 1 is controlled by controlling the drive motor 20. A plating film is formed by moving and passing through the plating electrode 7, and the temporarily applied abrasive grains are fixed in plating, and the plated portion of the long material 1 is then passed through the die device 7b.
After being handled by the inspection device 13, the inspection device 13 performs an inspection. A detection signal of the diameter of the plating covering part is applied to the control device 17, and the next finishing plating electrode 14,1
6, additional plating and de-plating are performed based on the inspection results. The convex portions are removed by plating, the concave portions are additionally plated, and the drive motor 2
When the inspection part moves and passes the finish plating electrodes 14 and 16 by the travel control of 0, the switch 18,
Appropriate high-precision finishing can be achieved by controlling the position and plating phase for switching and energizing 19.

The finish-plated long material is washed and dried and wound onto the winding frame 3, and by continuously performing this process, it is possible to easily manufacture a wire tool of the long material. Using high tensile strength wire such as iron or tungsten as a long material, a wire tool whose surface is plated with a good conductor such as Cu, Ni, or Al can be easily obtained with high accuracy and equal wire diameter. Therefore, there are fewer disconnections,
It can run with high tension and enables high precision machining.

As shown in the figure, pulse plating allows for high-density plating, and it is extremely easy to control the wire diameter, including the plating thickness.
Finished with accuracy within 1μ. Of course, Metsuki can also use DC current, AC current, pulsating current, etc. as appropriate.
In either case, the plating process is a continuous process of inspecting the plating film, then additional plating, and finishing plating to remove plating, making it easy to manufacture highly accurate tools. For example the diameter
When hard particles of approximately 60μφ were adhered to a piano wire of 0.6mmφ, the accuracy of the unevenness of the plating layer was 0.68 to 0.69mm in terms of the difference between the maximum and minimum diameters.

As described above, according to the present invention, the plating covered portion by plating is inspected after processing, and depending on the inspection results, additional plating is performed or finish plating is performed to remove the plating. By performing this process continuously, cutting,
Since wire tools for grinding are manufactured, wire tools with good precision can be easily obtained. In both rough plating and finish plating, a high-quality plating film can be formed at high speed by plating while jetting the plating liquid from the electrode jet hole as in the embodiment.
