Description

Detailed Description of the Invention The present invention ζ, I, spinning 11-karat gold, in particular, the cross section of the stock solution discharge hole at the tip of the spinning hole is irregularly shaped, and the 11 stock solution discharge holes expand in at least two directions centering on the intersection point. The present invention seeks to improve the method for producing spun 11-karat gold material, which consists of joint partial discharge holes.

Conventionally, the stock solution discharge hole at the tip of the gold spinning hole for spinning 1" gold was 91 degrees of the irregularly shaped stock solution discharge hole 1 as shown in FIG. Plasticity J
- I can't think of a way to create a hole by law.

However, in this method, there is a 1lLJ field at the length of the original t^111 hole 1, and the length of the jlV chitopillary,
nl (the width of one side of the outlet la is 0.05 m++,
When the hemorrhoid size is about 51, the panday ■-guji becomes very fragile and easily breaks, so the capillary and the gas (1,
After 11Im, the machining becomes extremely difficult, and it becomes impossible to process the raw material.

Moreover, the capillary retention is 0. The shortest letter after l** and J
Therefore, not only the life of the liquid discharge hole I is shortened due to wear, but also the thread thickness becomes uneven.1. B. As for spinning I-1 gold, quality 7++ is poor.

For this reason, for example, the discharge pressurization method (Me is L・-
Zahino, method), 1, predetermined J method, 1, smaller size ([7] After melting the discharge hole, punch the direction of the melted soil), divide by r ril+ into the tool, and further approximate the discharge hole. A method is adopted in which the original ttl<discharge hole l of the predetermined 1J method is obtained by finishing with a slightly larger panday IR.

This electric discharge method (or laser beam method)

Addition of 1-1 to 100% is possible, and there is no unevenness in the thickness of the spinning time series.

(By removing the irregularities on the melting upper surface to make it mirror-like, it may obstruct the flow of the spinning solution, cause the spinning solution to stick, or cause damage to the spun yarn, resulting in low strength. 11
I'll be eliminated while uneven color removal occurs. 7i,t again? The approximate discharge hole, which was one length in the Tt machining method, is enlarged by (M) by adding 1il and 1method ζ. The wall surface of the hole 1 is free from unevenness such as cracks or scratches.

However, even with such an iW manufacturing method, there are the following problems. For example, as shown in No. 2 and 1, the stock solution discharge hole 1'
If the shape is such that the shape intersects in the shape of an i;ε angle at the intersection point P, especially when the acute angle is 90 degrees or less, the yarn discharged and spun from the stock solution discharge hole 1' has a cross-sectional shape of As shown in Fig. 3, there is no stiff part, and the outer surface of the V difference part becomes a curved thread 2.

This is a punch lug for preparing the discharge hole 1' to the raw material l.
When making tools, the acute angle part is 90 degrees IF, for example, 30 degrees, because the wear of the shell on which the sharp angle is formed is significant, so the originally acute angle part becomes a curved shape, and this is the reason. The yarn that is punched with a punch tool and then spun by discharge from the stock solution discharge hole 1' naturally has no sharp spots, and there is no sharpness at the intersection (this is due to the fact that the surface is curved).

To explain this in more detail, for example, S
Since a relatively strong and hard material such as 2LR steel with I<I+ is used, in order to shape it into a puncher tool according to the specified J method, the angle of 30 degrees is required even if it is a diamond-containing f-shaped tool. If you obtain a punch with an acute angle of 4, the shape of the punch should be 30 degrees. It is I4 that it is a fixed form.
．． p, and from this, fδ form ``2! ■ Beyond 1j1
The strength of the first part is almost 21! ? ＜, Of course C bread (
When shaping one tool (l), the wear of the punch was significant, and the tool was a punch 4 with an acute corner 3 having a curved surface, as shown in Fig. 4. Setting r i
In addition, as shown in Fig. 21, the yarn to be drawn and spun is free of bulge, as shown in Fig. 3. A saw with a curved surface.

The present invention has been made to solve such problems,
Spinning 1-' in which the acute angle of the stock solution discharge hole is made sharp, where the intersecting angle of the congruent partial discharge holes, which have irregular shaped tlIIIIIIi planes and are centered on 14 intersection points and expand in at least two directions ζ, is an acute angle. The present invention provides a method for producing gold.

An embodiment of the method for producing gold by spinning according to the present invention is illustrated and explained as follows. As shown in FIG. 5, the stock solution discharge holes 1'' are made up of joint partial discharge holes 1a whose cross section is irregularly shaped and which extend in at least two directions, in this example, in four directions, with the intersection point I) as the center. The spinning hole 5 shown in FIG.
As shown in 1-1 to produce spinning yarn 1-1 gold 6 having a large number of
is punched with punch soil J-11,I, and then the approximate discharge hole 1 (+ is punched with punch tool 12a, as shown in FIG. 7C)
] 2b, 12c=i When the stock solution is slightly enlarged by a plastic working method and delivered to a discharge hole 1'' having a specular wall of a predetermined =J method, the joint partial discharge is performed as shown in FIG. Slightly enlarge any of the holes 1a - (1^1) and raise it to the "C predetermined" method, then sequentially open each partial discharge hole 1a.
The discharge holes 1a are enlarged by 1 and 2 to achieve a predetermined XJ method, or, as shown in FIG.

As described above, in the method for manufacturing a spinneret of the present invention, when forming the stock solution discharge hole I11 having a mirror wall of a predetermined method, one of the joint partial discharge holes 1a is slightly enlarged by a predetermined method. After applying the method (1 knee), sequentially open each partial discharge hole 1a.
The undiluted solution discharge hole I11 can be obtained by increasing the size of the undiluted solution discharge hole I11 by increasing the size of each conjoint partial discharge hole 1a, or by increasing the size of each conjoint partial discharge hole 1a alternately and finishing it in a predetermined manner.
Since 1' is (7), the acute angle portion lJ of the intersecting angle of each partial discharge hole 1a of the resulting stock solution discharge hole 1'' becomes a sharp edge.

In addition, in the method of manufacturing the spun IT gold of the present invention, each partial discharge hole 1a is enlarged slightly, without using a punch upper tool having the same shape as the stock solution discharge hole IIT. Since the punch used for this purpose can be made in a very simple slit shape, it is easy to manufacture, and it is possible to produce a punch with an accuracy of 10 times higher than that of the iJ method.

In addition, the example described in 2 is an example in which 1ItIJ of spun L1 gold having an elongated X-shaped stock solution discharge hole was manufactured, but the invention is not limited to this. type,
Similarly, in the case of undiluted solution discharge holes such as a rice-shaped 9-point shape, the acute angles of the intersecting angles of each partial discharge hole have a sharp etch.
There are things you can do.

As mentioned above, according to the method of spinning 1-1 gold of the present invention, the cross section has an irregular shape and is centered at the intersection r, +1.

-ζThe angle at which the congruent partial discharge holes that extend in at least two directions intersect is an acute angle.The mirror corner of the undiluted solution outlet hole is set at a sharp edge. It has the excellent effect of being able to discharge and spin striped threads and to spin only 1" gold. Also, after drilling a discharge hole with a shape similar to the stock solution discharge hole, drill each partial discharge hole.
The Pandey ILR used for this has an extremely simple structure, as it is easy to manufacture and can be produced with high precision using a single method. Therefore, the above-mentioned spinning [in the method for producing 21k gold]
It is possible to create a stock solution discharge hole with a high degree of flexibility.
