DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of a thermal spraying composite wire manufacturing apparatus according to the invention will be described with reference to the accompanying drawings.
FIG.1 and FIG.2 is the top view and front view of the composite wire manufacturing apparatus for thermal spraying which concern on one Embodiment of this invention.
As shown in FIGS. 1 and 2, the thermal spray composite wire manufacturing apparatus 10 of the present embodiment includes a hoop material unwinding roller 12, an upstream wire forming unit 14, a powder supply unit 16, an intermediate winding roller 18, and a downstream wire. The molding means 20, the final winding roller 22, and the like are provided, and each member is installed at a predetermined location on the apparatus base 11. Moreover, although not shown in figure, the control board connected to each apparatus, such as a motor, is provided, and each apparatus is controlled in the case of wire manufacture.

3A is a detailed view of the hoop material unwinding roller 12, FIG. 3A is a view from the front side, FIG. 3B is a view from the front side, and FIG. FIG. 3 is a schematic perspective view of the unwinding roller 12 as viewed from the side.
As shown in these drawings, the hoop material unwinding roller 12 includes a circular roller portion 12A around which the hoop material 1 is wound, a constant tension unit 24, an electromagnetic brake 26, and the like. One end of the rotary shaft 12B is fixed to the center of the circular roller portion 12A, and the rotary shaft 12B is rotatably supported by bearings 28, 28 attached to the apparatus mount 11.
The other end of the rotating shaft 12B is connected to an electromagnetic brake 26 so that the rotation of the circular roller portion 12A can be braked as necessary.

The constant tension unit 24 includes a touch roll unit 24A, an arm 24B, and a pivot sensor 24C. The flat roll unit 24A comes into contact with the surface of the flat hoop material wound around the circular roller unit 12A. A change in the winding diameter of the hoop material is detected by a pivot sensor 24C. That is, the arm 24B follows the change in the winding diameter (roll diameter) of the flat hoop material wound around the circular roller portion 12A, and rotates in an arc shape around the pivot sensor 24C. By detecting this rotation as a change in the angle of the arm 24B by the pivot sensor 24C, the winding diameter (roll diameter) of the flat hoop material is detected. Based on the detection result, the braking force of the electromagnetic brake 26 is controlled to maintain the tension generated in the flat hoop material within a certain range.

FIG. 4 is a schematic side view showing the front wire forming means 14. As shown in the figure, the front wire forming means 14 includes a total of 13 roller dies, and forms the flat hoop material 1 from a flat shape to a U-shape by four units 101 to 104.
Further, four units 105 to 108 are molded from a U-shape to a round shape, and five units 109 to 113 are molded into a tube shape having an outer diameter of 4 mm. Furthermore, there is a distance of 70 mm between 104 and 105, and the powder supply means 16 is installed in this upper part, and the powder which becomes the function manifesting substance of the thermal spray coating is supplied.

Each cassette roller die is provided with a not-shown roll gap adjusting bolt, which is a bolt for adjusting the roll gap, and can be adjusted to a predetermined size when the material and width of the hoop material are changed. .
For each cassette roller die, two reduction screws are attached to the left and right in the downward direction, or two in the vertical direction in the horizontal direction. Depending on whether the cassette roller die is set vertically or 90 ° horizontally, the position of the bolt is left and right or up and down. When the reduction screw is rotated once, the roller gap moves 3 mm or 2 mm. At the time of adjustment, the rotation angle of the reduction screw is set to be the same for both the left and right or top and bottom so that the material to be processed, for example, a hoop material, passes through the central part of all the connected cassette roller dies.

FIG. 5 is a view showing the powder supply means 16, FIG. 5 (a) is a schematic view in a state where the roller die is omitted, and FIG. 5 (b) is an external view of FIG. 5 (a) from the direction of the arrow Vb. FIG. As shown in these drawings, the powder supply means 16 includes a primary feeder 30, a secondary feeder 32, and a tertiary feeder 34.
The primary feeder 30 is provided between the primary feeder 30 and the secondary feeder 32 by forcibly scraping the powder of the thermal spray material accommodated in the accommodating portion 30 </ b> A by the guide blades disposed therein. Quantitatively supplied to the hopper 38 of the secondary feeder 32 through the chute 35 (as an example, a high-precision small-sized quantitative feeder MO-180R manufactured by Yoshikawa Corporation). A laser sensor 36 is attached to the side surface of the chute 35, and the amount of powder supplied from the primary feeder 30 to the secondary feeder 32 is measured to detect powder breaks.

The secondary feeder 32 includes a screw feeder 39 (for example, FEEDCOM-μM manufactured by Nissin Engineering Co., Ltd.) that quantitatively supplies a small amount of powder, and the like. The fixed amount of screw is supplied to the tertiary feeder 34 side by the rotation of the screw.
The tertiary feeder 34 is provided with a trough 40 formed in a bowl shape for conveying powder in the lateral direction on the apparatus base 11 via a leaf spring, a fixed frame, and a vibration applying unit 37 (not shown). The vibration applying unit 37 is provided with an electromagnet. An AC half-wave pulsating current is applied to the coil of the electromagnet, and the trough 40 is slightly vibrated by the attraction force or the repulsive force of the electromagnet according to the current. Quantitatively supply while moving each (as an example, small electromagnetic feeder CF-1 manufactured by Shinko Electric Co., Ltd.).

A final throwing chute 42 is provided on the end side of the trough 40, and the roller die No. 4. And No. In between, the powder is put into the hoop material 1 molded into a U-shape. A vibrator 44 and a laser sensor 46 are installed on the side of the charging chute 42 to prevent the powder from adhering to the final charging chute 42 due to the vibration of the vibrator 44, and the flow of powder supplied by the laser sensor 46, and The amount of powder charged into the hoop material 1 is monitored. The amount of the powder is calculated by measuring the distance between the final throwing chute 42 and the powder by detecting the reflected light of the laser light emitted from the sensor 46. As a result, the amount of powder filled in the composite wire can be finely controlled, making it possible to produce a wire with a desired filling rate.

In a composite wire, it is important to keep the powder filling rate as constant as possible, but the density, particle size, particle size, and fluidity of the filling material differ depending on the type of material. For this reason, in order to make the filling rate constant, three types of supply devices having different supply methods, that is, the primary feeder 30, the secondary feeder 32, and the tertiary feeder 34 are adopted, and the laser sensor 46 etc. The supply amount is controlled to enable quantitative supply. The powder is supplied stepwise from the feeders 30, 32, and 34 through a path indicated by a dashed line A in FIG.

6 is a view showing the intermediate winding roller 18, FIG. 6 (a) is a schematic view, and FIG. 6 (b) is a view of FIG. 6 (a) viewed from the direction of the arrow VIb.
As shown in these drawings, the intermediate winding roller 18 includes a rotating roller 18A, a gear box 18B, a drive motor 18C, and the like. The rotating roller 18A has a disk shape with a predetermined outer diameter, and A rotating shaft is installed in the vertical direction, and the rotating roller 18A rotates in the horizontal direction.
The gear box 18B is connected to a drive motor 18C, and the gear box 18B decelerates the rotation of the motor 18C, and rotationally drives the rotating roller 18A at a predetermined rotational speed. A tube-like wire formed by the former wire forming means 14 is wound around the outer peripheral portion of the rotating roller 18A, and the tension is shared between the wire forming means 14 and the latter wire forming means 20. An MC nylon wire guide is installed on the intermediate winding roller 18 to prevent winding. Note that the rotational direction of the rotary roller 18A is set to the horizontal direction, and the installation position of the drive motor 18C is low, which eliminates the possibility that the powder contained in the wire moves due to gravity and consequently causes uneven filling. This is because the center of gravity of the entire apparatus can be lowered.

That is, the intermediate take-up roller 18 bears the tensile force necessary for forming the hoop material by the pre-stage wire forming means 14, and the composite wire between the intermediate take-up roller 18 and the final take-up roller 22 is formed with a cassette roller die. In this structure, only the tension necessary for forming the wire and the tension necessary for the frictional force for preventing the wire from slipping on the intermediate winding roller 18 are applied. For this reason, if the wire is wound only by the final winding roller 22, the composite wire may be broken by the tension caused by the molding. However, by adopting the above configuration, the possibility is greatly reduced. It became possible. This eliminates the need for a lubricant that has been necessary in the past and helps simplify the manufacturing process.

As shown in FIG. 8, the individual wire outer diameter molding portions 20B, 20C, and 20D are installed on slide units 48B, 48C, and 48D supported so as to be movable back and forth with respect to the apparatus base 11. The slide units 48B, 48C, and 48D are movably disposed with respect to the apparatus base 11 by the screw shafts 50B, 50C, and 50D, and the handles 52B and 52C attached to the screw shafts 50B, 50C, and 50D. , 52D can be rotated to move the respective molding parts 20B, 20C, 20D back and forth so that they can be retracted from the molding path or positioned on the molding path.

Of the individual wire outer diameter molding portions 20A, 20B, 20C, and 20D, the molding portion 20A further converts the composite wire 1 molded to an outer diameter of 4 mm by the former-stage wire molding means 14 to an outer diameter of φ3.2 mm, and the molding portion 20B is an outer portion. The wire is drawn so that the diameter is 2.5 mm, the molded portion 20C has an outer diameter of 2.0 mm, and the molded portion 20D has an outer diameter of 1.6 mm.
When the composite wire 1 is drawn to an outer diameter of 3.2 mm, as shown in FIG. 8-1 (a), the molding parts 20B, 20C, and 20D are retracted from the molding path and retreated. The wire drawing process is performed by the portion 20A, and the wire is molded into a wire having an outer diameter of φ3.2 mm. When drawing to an outer diameter of 2.5 mm, as shown in FIG. 8-1 (b), the molding parts 20C and 20D are retracted from the molding path and the molding parts 20A and 20B are used. Perform the wire drawing process. Further, when the outer diameter is set to 2.0 mm, the wire drawing step is performed by the molding parts 20A, 20B, and 20C with the molding part 20D retracted from the molding path as shown in FIG. 8-2 (a). I do. When the outer diameter is φ1.6 mm, as shown in FIG. 8-2 (b), by performing the wire drawing process using all the molded parts 20 </ b> A, 20 </ b> B, 20 </ b> C, 20 </ b> D, Mold into composite wire.

7 and 8-1 and 2, in order to disperse the tension applied to the composite wire 1 in the middle of the cassette roller dice unit of the individual wire outer diameter molding portions 20 </ b> A, 20 </ b> B, 20 </ b> C, and 20 </ b> D. A pair of upper and lower auxiliary feed rollers 54A, 54B, 54C, and 54D are provided, and each of the rollers 54A, 54B, 54C, and 54D is rotationally driven by the auxiliary motors 56A, 56B, 56C, and 56D to the wire 1 during molding. On the other hand, tensile force (pull) and pushing force (push) are applied to disperse the tension generated in the entire wire 1.
Further, since the upper and lower rollers 54A, 54B, 54C, 54D can finely adjust the clamping force with respect to the wire 1 from above and below by a push bolt provided with an elastic body such as a spring on one or both of them. It is possible to set the pinching pressure most suitable for forming the wire 1.
Furthermore, each of the auxiliary motors 56A, 56B, 56C, and 56D can be controlled by selecting the number of rotations individually. That is, overall automatic control including the auxiliary motors 56A to 56D is performed together with the rotation speed of the hoop material unwinding roller 12 and the rotation speed of the final winding roller 22 (to be described later) so as to optimize the molding speed. Thus, the manufacturing speed can be improved. Further, since the tension applied to the wire is dispersed, smooth wire molding can be performed without using a lubricant, and at the same time, prevention of wire breakage during molding can be achieved.

The winding position of the wire 1A is guided while sliding the guide 70 in the lateral direction. That is, for the composite wire 1A taken up by the final winding roller 22, the guide wire 70 guides the composite wire 1A to an appropriate position on the outer peripheral surface of the final take-up roller 22 so that no turbulent winding occurs. It is possible to take it.

The thermal spraying composite wire manufacturing apparatus 10 of the present embodiment configured as described above is operated as follows during wire manufacturing. As the thermal spraying method using composite wires progresses, the types of wires required, i.e. various hoop materials such as aluminum and stainless steel, and various types of powder particles that serve as function-expressing substances are extremely diverse.

As a result of the experiment, the most suitable conditions were accumulated as operation control data in consideration of the width dimension of the flat hoop material, the outer diameter of the composite wire, the type of powder, and the like. And the control program of an operation system is built based on these control data, and it is trying to manufacture wire efficiently continuously by controlling each apparatus automatically. In addition, in the event of abnormalities during continuous automatic operation, an alarm was issued using a patrol light, and an emergency stop system was simultaneously used to improve safety.
