Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas or liquid ejecting apparatus for ejecting a work after a press such as a press machine or removing scraps by ejecting compressed air or a liquid.

[0002]

2. Description of the Related Art Heretofore, a gas or liquid jetting device has generally been used which jets air or liquid by detecting before and after the bottom dead center of a press such as a press and actuating a solenoid valve.

[0003]

In recent years, when the speed of equipment is increased (for example, when the speed of a press machine is about 300 spm is increased to 500 spm or more),
With the solenoid valve, the speed cannot be followed, work removal and scrap removal cannot be performed, and for example, compressed air is always blown out to respond, and the air compressor is constantly burdened to ensure air at a constant pressure. Was inefficient. The present invention is intended to provide an efficient gas or liquid jetting device that jets out only when a work is taken out or scraps are removed corresponding to a high-speed device.

[0004]

In order to solve the above-mentioned problems, the gas or liquid jetting device of the present invention has a pressing means mounted on the up-and-down movable part of the main body device for producing a product by moving up and down. The upper die, the communication hole, and a switching pin having a connecting hole which is provided so as to intersect with the communication hole and which connects the communication hole, and a vertically movable part of the main body device are moved downward to cause the pressing means of the upper mold to move. Except when pressing the switching pin, the main body is provided with a normal pressure means that presses the switching pin in opposition to the pressing means while sandwiching the switching pin so that the connecting hole and the communication hole are not continuous. The lower mold is attached to the main body of the apparatus.

[0005]

As described above, the present invention can be an efficient gas or liquid jetting device for surely jetting gas or liquid from a gas or liquid jetting device during work production only when the vertically movable part of the main body device is moved downward. It is a thing.

Reference numeral 6 denotes a lower die of an air ejection device having an air hole 7 (shown in FIG. 2) attached to the fixed portion 2, and an ejection port 8 of the air hole 7 and an air intake of the press die 4. The inlet 9 is connected by a pipe 10. Also,
An air inlet 11 of the lower die 6 is provided on the opposite side of the outlet 8 of the lower die 6 of the air ejection device, and the air pipe 12 is supplied by a compressor (not shown) to maintain a constant air pressure. A pipe 14 is connected to the valve 13.

Reference numeral 30 denotes an upper die mounted on the vertically movable part 3, and the lower die 6 is driven by the vertical movement of the upper die 30 to supply air to the press die when necessary.

Next, the detailed structure of an embodiment of the air ejection device of the present invention will be described with reference to FIG. According to the figure, the lower mold 6 is inserted into the spring holder 15 and the opening 15a of the spring holder 15, and the air switching pin 16 is inserted.
The spring 17 that pushes the air upward and the head portion 16a of the air switching pin 16 come into contact with each other, and the air switching pin 16
Foot 16 of the air switching pin 16 to prevent the jumping out of
Pin receiving plate 18 having a hole through which b is inserted, and air hole 7 having air intake port 11 and jet port 8 at both ends described above.
And the foot portion 1 of the air switching pin 16
6b, and a bush holder 20 holding a bush 19 through which 6b is inserted.

The air holes 7 are formed in the bush holder 2
It also penetrates 0 and does not penetrate at the position where the air switching pin 16 is pushed up by the spring 17, but at the position where the air switching pin 16 is pushed down by the downward movement of the upper mold described later. ,
A connecting hole 2 is formed in the air switching pin 16 so as to penetrate therethrough.
1 (having a smaller diameter than the other portion of the air switching pin 16) is provided.

Further, the bush 19 is made of so-called oilless metal, whereas the air switching pin 16 can be moved up and down, and the air from the air pipe 12 is set so as not to leak as much as possible. Has been done. If not necessary, the bush 19 is made of normal metal (iron, etc.).
And may be coated with oil or the like.
