DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory diagram showing an embodiment of a method of planting pins on a plate according to the present invention. In the method of arranging the pins on the plate body according to the present invention, the pins to be erected on the plate body are housed in a mold, and the plate body set on the other die is pressed with high pressure to the mold body. It is characterized in that a pin is inserted into the plate body.

The pin accommodating die is formed with a pin accommodating hole in advance in accordance with the arrangement to be planted on the plate body, and the die is formed with a die accommodating hole in accordance with the arrangement of the pin accommodating holes. In the method of the present invention, the center positions of the pin accommodating hole provided in the pin accommodating die and the die hole provided in the die are completely matched, and the hole diameter of the pin accommodating hole and the inner diameter of the die hole are matched with the outer diameter of the pin. The point is to form it exactly according to the diameter dimension to be formed.

The pin housing die is set so as to project a predetermined length from the die surface in a state where the pins are set in the die, and the pin tip portion projecting from the pin housing die penetrates into the plate body and is planted. To do it. Since the position of the pin housing hole in the pin housing die determines the pin position in the product, the position of the pin housing hole in the pin housing die is extremely important for pin placement accuracy.
Also, if the die hole is not formed accurately on the die side as well, the plate cannot be held accurately when the pin penetrates the plate, causing burrs, etc. Since it becomes impossible to drive, it is necessary to process with high precision.

In FIG. 1, reference numeral 10 is a plate body into which a pin is driven, and 12 is a pin to be erected on the plate body. The plate body 10 is positioned and set on the die 14, and the pins 12 are supported by the punch plate 16 and the stripper plate 18, which are pin housing dies. Punch plate 16 and stripper plate 18
A pin accommodating hole 20 for inserting and setting the pin 12 is provided therein. The pin accommodating hole 20 is formed perpendicularly to the die surface of the die 14, and the die 14 is provided with a die hole 22 aligned with the pin accommodating hole 20.

In the embodiment shown in FIG. 1, the pin accommodating hole 20 is formed through the punch plate 16 and the stripper plate 18. The backing plate 24 contacts the back surface of the punch plate 16 and regulates the position of the rear surface of the pin 12. When the pins 12 are planted in the plate body 10 in this way, first, the pins 12 are inserted into the pin storage holes 20 of the stripper plate 18 and the punch plate 16 in the mold open state.
Insert and set the plate body 10 on the die 14.
Set. Since the pin accommodating hole is accurately formed in accordance with the outer diameter of the pin, even if the pin accommodating hole is opened downward, the pin does not fall out when the pin is inserted.

Then, the punch plate 16, the stripper plate 18, and the backing plate 24 are lowered, and the plate body 10 is first held by the stripper plate 18 and the die 14, and the punch plate 16 and the backing plate 24 are further lowered. The outer peripheral side surface of the pin 12 is held by the stripper plate 18 and the punch plate 16, and the plate body 10 is pushed by the pressing force of the backing plate 24 to remove the scraps from the die hole 2
While being discharged to 2, it is driven into the plate 10. FIG. 1 shows a state in which the lower end surface of the pin 12 is driven in until it becomes flush with the lower surface of the plate body 10. Die 14 and punch plate 1
6, stripper plate 18, backing plate 24
Since all of them move accurately while being guided by the pressing device, no displacement occurs when the pins are planted. In this way, the pins can be set up with extremely high accuracy.

FIG. 2 is an explanatory view showing the operation of raising the pin. The pin 12 is brought into contact with the plate body 10 in an upright state (Fig. 2 (a)), the pin 12 is pushed into the plate body 10 (Fig. 2 (b)), and the pin 12 is ejected while ejecting the scrap 10a of the plate body 10. 2 is shown standing on the plate 10 (FIG. 2 (c)). After the pin 12 is erected, the eject pin 2 shown in FIG.
The product is held down by 6, and the punch plate 16 and the stripper plate 18 are raised to the original position as they are, so that the pins 12 are planted on the plate body 10 and remain, and a product in which the pins 12 are planted is obtained.

Although the embodiment shown in FIG. 1 is an example in which one pin 12 is planted in the plate body 10, it is of course possible to plant a plurality of pins at one time. In this case, pin housing holes and die holes are formed in the pin housing die and the die, respectively, and the pins are set in the respective pin housing holes and the pins are planted in the same manner as the above example. You can do it. Further, when the pin is set in the pin housing die, the pin may be projected by sticking the back surface of the pin at the time of pressing without setting the pin with the pin tip protruding. That is, various methods can be used to store the pins. Further, a conventional pressing mechanism can be used as a pressing means for driving the pin housing die and the die,
The planting operation may be performed by appropriately adjusting the pressing force and the pressing speed.

FIG. 3 shows an example of a product in which pins are actually planted on a plate by using the method of the present invention. 3 (a) is a plan view of the plate body 10 in which the pins 12 are erected, and FIG. 3 (b) is a side view. In this product, four pins 12 are planted on the plate body 10. Figure 3
As shown in (a), the planar arrangement position of the pin can be appropriately set according to the product, and a pin having an arbitrary length can be used.
When the pin is inserted into the plate body 10 like the pin 12a in the figure, it is also possible to project the end portion of the pin from the lower surface of the plate body and set it up.

In the case of the method of the present invention, as described above,
Since the pins are set up using the pin housing die and die, the pin arrangement with respect to the plate is determined by the precision of die production. In the current die production, it is possible to produce with an error of about several μm. Therefore, according to the above-mentioned pin erection method using a die, the pins can be erected with high accuracy.

Further, according to the method of the present invention, the pin position can be accurately determined with respect to the plate even in the case of arbitrary pin arrangement as shown in FIG. Further, since the direction of the pin can be accurately set and supported by the mold, the pin can be correctly set upright without being tilted at the time of planting. At the same time, the amount of protrusion of the pin from the mold can be set accurately by machining the mold, and the height position and the amount of protrusion of the pin in the planted state can be set accurately. As a result, it is possible to easily mix and use pins of various lengths.

In particular, as a feature of the method of the present invention, by accurately setting the die hole and the pin position of the pin housing die, the bottom surface of the plate body can be accurately identified by the die when the pin penetrates the plate body and is set up. The holes formed in the plate body at the time of pin penetration do not substantially expand in diameter, and the wall surface is formed straight. As a result, the pin is securely held by the wall surface of the penetration hole, and the pin is firmly held by the plate body. This means that even if the plate body is relatively thin, it is possible to reliably support the pins.
In the case of the conventional method in which holes are preliminarily drilled in the plate and then the pins are raised, the pin diameter that can be accurately erected on the plate should be about the same as the plate thickness or about 60% of the plate thickness. Although it was difficult to erect a pin having a diameter smaller than this, according to the method of the present invention, it is possible to erect up to about 1/2 of the conventional pin diameter. Actually, SK is applied to 1 mm thick plate material of SPC.
A pin with a diameter of 0.3 mm is planted with S2.

Further, according to the method of the present invention, it is possible to easily set a large number of pins on the plate body at one time. Since the pin arrangement can be set accurately by supporting the pins with a mold, it is possible to plant the pins accurately even if the pin interval is narrow. Then, by setting a large number of pins in the mold, the pins can be planted at once and the pins can be efficiently planted. The method of the present invention is extremely practical under the conditions in which a large number of pins are planted in the plate body with extremely high accuracy.

The material that can be used when the pins are erected on the plate according to the method of the present invention is not particularly limited, but in the embodiment shown in FIG.
0.6m of SAS420J2 as pin using m thick aluminum
The one with m diameter was used. The product after the pins were erected by the above-mentioned method could be erected vertically correctly without causing burrs in the pin-erected portion. The error in the plane arrangement of the pins was about 7 μm.

[0021]

As described above, according to the method and apparatus for planting pins on a plate according to the present invention, pins can be planted on the plate with extremely high accuracy and a large number of pins can be planted. It can also be done efficiently when the pins of (3) are planted in the plate. Further, by holding the pins in the pin housing die, it is possible to reduce variations in product accuracy during manufacturing, which is very effective.
