That is, the transfer structure 50 makes a forward linear motion along the guide rail 12 by driving the servomotor 14 for reciprocating linear motion, and the vacuum adsorber 60 and the tapping hole processing machine 70 and The female screw processing machine 80 and the laser marking machine 90 make a forward linear motion together, but the vacuum sucker 60 makes a linear motion until it is positioned on the chuck 40 for fixing the ball, and thus the vacuum sucker ( When the piercing ball 100 is seated on the chuck 40 for fixing the ball after the 60) descends as described above by the driving of the servomotor 16 for elevating, the chuck 40 for fixing the ball is pneumatic. (100) is clamped and fixed on all sides.

At this time, after the piercing ball 100 is fixed to the chuck 40 for fixing the ball, the vacuum adsorber 60, the hole processing machine 70 for tapping, the female thread processing machine 80 and the laser marking machine 90 are lifted together. do.

Next, as shown in FIG. 9 , the tapping hole processing machine 70 descends with respect to the piercing ball 100 fixed to the ball fixing chuck 40 by the driving of the lifting servomotor 16, The step of processing the tapping hole 102 in the piercing ball 100 while being rotated by the rotary motor 18 primarily proceeds.

To this end, the transfer structure 50 performs a linear motion backward a predetermined distance along the guide rail 12 by driving the servomotor 14 for reciprocating linear motion, and the vacuum adsorber 60 and the tapping hole processing machine ( 70), the female thread processing machine 80 and the laser marking machine 90, etc., perform a backward linear motion together, but the tapping hole processing machine 70 performs a backward linear motion until the hole processing machine 70 is positioned on the ball fixing chuck 40. .

Accordingly, the tapping hole processing machine 70 is lowered to the surface position of the piercing ball 100 on the ball fixing chuck 40 by the driving of the lifting servo motor 16, and the tapping hole processing machine 70 of the After the operation of the tapping hole processing pin 73 to concave the surface of the piercing ball 100 is preceded, the tapping hole processing pin 73 is rotated by the rotational force of the rotating motor 18 while tapping the tapping hole ( 102) is drilled.

At this time, when the tapping hole 102 is drilled in the piercing ball 100 while the tapping hole processing pin 73 is rotated, the inner peripheral end of the tapping hole 102 is lowered so that a seat for forming a female thread is provided. is bent

On the other hand, as shown in FIG. 9 , when the tapping hole processing machine 70 descends to the surface position of the piercing ball 100 on the ball fixing chuck 40, the female thread processing machine 80 is stored in the lubricant reservoir 94. It descends together towards the lubricant.

Therefore, before the female thread processing machine 80 processes the female thread on the inner diameter part of the tapping hole 102 that is primarily processed in the piercing ball 100, the female thread processing pin 83 is stored in the lubricant oil reservoir 94. The lubricating oil is applied to the surface of the female thread processing pin 83 to prevent damage to the piercing ball due to the frictional force when the female thread processing pin 83 processes the female thread to the piercing ball 100. is in

At this time, after the hole 102 for tapping for the piercing ball 100 is processed by the female thread processing machine 80, the vacuum adsorber 60, the tapping hole processing machine 70, the female thread processing machine 80 and the laser The marking machine 90 moves up and down together.

Next, as shown in FIG. 10 , after the step of processing the tapping hole 102 first, the female thread processing machine 80 is lowered by the driving of the elevator servo motor 16 , and then, by the rotary motor 18 A step of processing the female screw 104 in the inner diameter of the tapping hole 102 of the piercing ball 100 fixed to the chuck 40 for fixing the ball while rotating is performed.

To this end, the transfer structure 50 performs a linear motion further back a predetermined distance along the guide rail 12 by driving the servomotor 14 for reciprocating linear motion, and the vacuum adsorber 60 and the tapping hole processing machine (70) and the female screw processing machine 80 and the laser marking machine 90, etc., do a more backward linear motion together, but the female screw processing machine 80 performs a backward linear motion until it is positioned on the chuck 40 for fixing the ball. .

Accordingly, the female thread processing pin 83 of the female thread processing machine 80 enters the inner diameter of the tapping hole 102 of the piercing ball 100 and rotates, thereby fastening the piercing shaft to the inner diameter of the tapping hole 102. For the female thread 104 is machined.

Next, as shown in FIG. 12 , the vacuum adsorber 60 vacuums the piercing ball 100 in which the tapping hole 102 and the female thread 104 are processed together with the release of the clamping of the chuck 40 for fixing the ball again. By falling to the product storage box 92 after adsorption, the piercing ball 100 for commercialization is collected.

On the other hand, after the step of processing the female screw 104 to the piercing ball 100 by the female screw processing machine 80 secondarily, as shown in FIG. 11 , the laser marking machine 90 is transferred over the chuck 40 for fixing the ball Thus, the step of marking a predetermined pattern on the outer peripheral surface of the tapping hole 102 of the piercing ball 100 may be further progressed.

As seen above, the first automatic processing of the tapping hole 102 in the piercing ball 100, which is one of the configurations of piercing accessories for body decoration, and the piercing shaft 202 in the inner diameter of the tapping hole 102 ), by automatically processing the female screw 104 capable of fastening the screw, workability and productivity can be greatly improved compared to the existing manual processing.

Appearance molding process of the piercing ball

For external shaping of the piercing ball, the piercing ball 100 is transferred to the first chuck 301 or the second chuck 302 for ball shaping. If you want to shape the appearance of the piercing ball 100 in a triangular shape, it is transferred to the first chuck 301 for ball shaping, and when you want to shape the appearance of the piercing ball 100 into a square, the second chuck for ball shaping ( 302) is transferred.

In the following description, a process of forming the appearance of the piercing ball 100 by transferring the piercing ball 100 to the second ball forming chuck 302 will be described.

The piercing ball 100 is transferred to the chuck 302 for forming the second ball through the vacuum adsorber 60 . At this time, the piercing ball 100 is transferred to the vacuum absorber 60 and is seated on the second ball seating table 370 of the second ball forming chuck 302, and the vacuum sucker 60 is the piercing ball 100. In order to prevent the flow of the piercing ball 100 can be maintained in an adsorbed state.

When the piercing ball 100 is seated on the second ball seating table 370 , the four second ball forming arms 380 of the second ball forming chuck 302 move forward toward the piercing ball 100 to pierce the piercing ball 100 . The outer surface of the ball 100 is molded into a square shape.

In this process, in order for the four second ball forming arms 380 to advance, the second servomotor 610 and the reducer 620 are driven to reverse the screw shaft 631 of the ball screw 630 (eg, For example, when rotated counterclockwise), and the screw shaft 631 rotates in the reverse direction, the nut 632 descends along the screw shaft 631. Since the nut 632 is connected to the elevating plate 510, The elevating plate 510 is lowered.

When the elevating plate 510 descends, the second movable member connection bar 530 connected to the upper end of the elevating plate 510 descends together with the elevating plate 510, and the second movable member connecting bar 530 descends. As a result, the second shaft 362 connected to the second movable member connecting bar 530 is lowered, and the second elevating block 361 coupled to the second shaft 362 is lowered.

When the second elevating block 361 is lowered, the fifth tapered surface 3612a formed on each of the four second arm linkage parts 3612 of the second elevating block 361 is formed by the four second ball forming arms 380 . ) While sliding downward along the seventh tapered surface 3812 of each second forward and backward block 381, the second forward and backward block 381 is pulled, and the four second ball forming arms 380 are piercing balls ( 100) is advanced.

As the four second ball forming arms 380 are advanced toward the piercing ball 100, the second ball pressing surface 3821 of the front end of the second forming bar 382 presses the outer surface of the piercing ball 100 and , Accordingly, the outer surface of the piercing ball 100 may be molded in a rectangular shape.

When the forming of the piercing ball 100 is completed, the four second ball forming arms 380 are spaced apart from the piercing ball 100 .

To this end, the second servomotor 610 and the speed reducer 620 are driven to rotate the screw shaft 631 of the ball screw 630 in a forward direction (eg, clockwise), and the screw shaft 631 moves in the forward direction. When rotated to , the nut 632 rises along the screw shaft 631 . Since the nut 632 is connected to the elevating plate 510 , the elevating plate 510 rises.

When the elevating plate 510 rises, the second movable member connecting bar 530 connected to the upper end of the elevating plate 510 rises together with the elevating plate 510, and the second movable member connecting bar 530 rises. As a result, the second shaft 362 connected to the second movable member connecting bar 530 rises, and the second elevating block 361 coupled to the second shaft 362 is raised.

When the second elevating block 361 is raised, the sixth tapered surface 3612b formed on each of the four second arm linkage parts 3612 of the second elevating block 361 is formed by the four second ball forming arms 380 . ) Slide the second forward and backward blocks 381 while sliding in the upward direction along the eighth tapered surface 3813 of each of the second forward and backward blocks 381, so that the four second ball forming arms 380 are piercing balls ( 100) and backwards away from it.

Then, when the four second ball forming arms 380 are spaced apart from the piercing ball 100 , the vacuum adsorber 60 drops the molded piercing ball 100 into the product storage box 92 .

As described above, when it is desired to shape the appearance of the piercing ball 100 in a triangular shape, it is transferred to the first chuck 301 for forming a ball. Since the forming process is the same as or similar to the process of forming the piercing ball 100 in the second ball forming chuck 302 , a detailed description thereof will be omitted.

20 is a view showing the appearance of a piercing ball formed in a triangular shape using the first chuck for ball forming shown in FIG. 14, and FIG. 21 is a view showing the first ball forming chuck shown in FIG. It is a view showing the appearance of a piercing ball molded in a hexagonal shape, and FIG. 22 is a view showing the appearance of a piercing ball molded in a rectangular shape by using the second ball-forming chuck shown in FIG. Through one process, the piercing ball 100 having a triangular and rectangular appearance as shown in FIGS. 20 and 22 using the first chuck 301 and the second chuck 302 for ball shaping ) can be produced.

Since the automatic tap processing and automatic appearance molding apparatus of the piercing ball according to an embodiment of the present invention can perform the tap processing process of the piercing ball and the appearance molding process of the piercing ball in one device, the tap processing and appearance of the piercing ball There is an advantage in that the molding process is accelerated, and workability and productivity can be greatly improved compared to manual work.

In addition, there is an advantage in that the process of forming the appearance of the piercing ball into a polygonal shape is easy, and the production of round and polygonal piercing balls is possible.

On the other hand, the automatic tab processing and automatic appearance molding apparatus of the piercing ball according to an embodiment of the present invention may be configured such that the first chuck 301 and the second chuck 302 for ball shaping are rotated.

The structure in which the first chuck 301 for ball forming and the second chuck 302 for ball forming are rotated is to rotate the first chuck 301 for ball forming and the second chuck 302 for ball forming in a horizontal direction. Any structure that can be made is possible.

Although not shown, for example, a pinion and a pinion installed on the first shaft 322 and the second shaft 362 of each of the first chuck 301 and the second chuck 302 for ball forming are rotated. It may consist of a rack. In this case, the first shaft 322 and the second shaft 362 may be configured to freely rotate on the first movable member connection bar 520 and the second movable member connection bar 530 .

As such, when the first chuck 301 for ball shaping and the second chuck 302 for ball shaping are rotated, the piercing ball 100 is first pressed to shape the appearance in a square shape and a triangular shape, and then the first ball By rotating the shaping chuck 301 and the second ball shaping chuck 302 to press the corners of the square shape and the triangular shape again, it can be formed into a hexagon as shown in FIG. 21, and although not shown, octagonal and angular can also be molded.

On the other hand, the automatic tab processing and automatic appearance molding apparatus of the piercing ball according to an embodiment of the present invention prevents and removes the adhesion of contaminants of the first chuck 301 and the second chuck 302 for ball molding. An antifouling coating layer made of an antifouling coating composition may be applied to achieve this effectively.

The antifouling coating composition contains cocoamphodiacetate and alkyl glycol ether in a molar ratio of 1:0.01 to 1:2, and the total content of cocoamphodiacetate and alkyl glycol ether is 1 to 10% by weight based on the total aqueous solution. am.

The cocoamphodiacetate and the alkyl glycol ether have a molar ratio of 1:0.01 to 1:2, and when the molar ratio is out of the above range, the first chuck 301 and the second chuck 302 for forming a ball There is a problem in that the coatability of the phase is lowered or the water absorption on the surface increases after application, so that the coating film is removed.

The cocoamphodiacetate and alkyl glycol ether are preferably 1 to 10% by weight in the aqueous solution of the entire composition, and when it is less than 1% by weight, the coatability on the first chuck 301 and the second chuck 302 for ball molding There is a problem of this decrease, and when it exceeds 10 wt%, crystal precipitation is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the present antifouling coating composition on the first chuck 301 for ball shaping and the second chuck 302 for ball shaping, it is preferable to apply by a spray method. In addition, the final coating film thickness on the first chuck 301 for ball shaping and the second chuck 302 for ball shaping is preferably 550 to 2000 angstroms, more preferably 1100 to 1900 angstroms. If the thickness of the coating film is less than 550 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2000 Å, there is a disadvantage in that crystal precipitation on the coated surface is easy to occur.

In addition, the present antifouling coating composition can be prepared by adding 0.1 mol of cocoamphodiacetate and 0.05 mol of alkyl glycol ether to 1000 ml of distilled water and then stirring.

On the other hand, the surface of the first cylindrical housing 310 and the second cylindrical housing 350 of the automatic tab automatic processing and automatic appearance molding apparatus of the piercing ball according to an embodiment of the present invention is corroded to prevent corrosion of the metal surface. An anti-coating layer may be applied.

The coating material of this anti-corrosion coating layer is triethanolamine 15% by weight, indiazole 25% by weight, hafnium 20% by weight, molybdenum emulsified (MoS2) 10% by weight, titanium oxide (TiO2) 15% by weight, propionamide 15% by weight. and the coating thickness can be formed to be 8㎛.

Triethanolamine, indiazole, and propionamide act as corrosion protection and discoloration protection.

Hafnium is a transition metal element with corrosion resistance, and serves to have excellent waterproofness and corrosion resistance.

Molybdenum emulsified plays a role in imparting lubricity and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the constituents and the coating thickness were numerically limited as described above, the inventors of the present invention repeatedly failed several times and analyzed through the test results. As a result, the optimal anti-corrosion effect was exhibited at the above ratio.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention.
