DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air blow device for a lower surface of a work of a turret punch press.

[0002]

2. Description of the Related Art In a conventional turret punch press, each die punch on each upper / lower turret (disk) is pressed.
Conventionally, for lubrication and cooling of a die, air blow (blow) from the upper surface of the work and oil mist of a pinpoint lubler from the lower surface of the work to the work between the punch and the die. Has been done.

FIG. 2 is a schematic diagram of a pinpoint tumbler of an air blow device from below the die D on the lower surface of the work W. Reference numeral 3 denotes a part of a lower turret (disk) in which a lower mold die is mounted in a die holder (not shown) at an upper part thereof, and 10 denotes a scrap discharge hole communicating with an opening of the die (not shown). Is shown.

[0004] The ring-shaped device 20 as an air blow device of the pinpoint rubler is an annular body of a hollow tube, and has a plurality of oil mist ejection holes 21 on its inner diameter.
Oil mist is supplied to the inside of the ring through an air source, a regulator, a lubricator, and a conduit (not shown). The oil mist M is injected and supplied to the section to perform desired lubrication and cooling.

[0005]

However, in the above-described conventional configuration, the ring-shaped device 20 is disposed in the chip discharge hole 10 of the lower turret 3,
When the scraps are scrapped, they may be clogged by being caught by the ring, which may impair workability.

The present invention has been made in view of the above situation, and has as its object to provide a space-saving and effective air blow system for the lower surface of a work for solving the above problems.

[0007]

SUMMARY OF THE INVENTION Accordingly, in the present invention, an object of the present invention is to achieve the above object by providing a work lower surface air blow device for a turret punch press as described below.

[0008] In the turret punch press, the turret and the die holder communicate with the pipes formed in the turret and the die holder through shot pin pipes specially provided on one side surface of the lower turret. An air blast device for a turret punch press, wherein a predetermined oil mist source is injected through an electromagnetic valve from an oil mist outlet opening to the inner surface.

[0009]

According to the structure of the present invention as described above, the lubricating property and cooling property of the punch / die can be improved to prevent welding and the like, the life of the punch / die can be improved, and the circulation of the scrap discharge hole can be improved. Since there is no hindrance, there is no fear of a decrease in work efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of the configuration of an embodiment according to the present invention, wherein FIG. 1 (a) is a schematic diagram of the overall configuration and arrangement, and FIG.

(Structure) In FIG. 1A, reference numeral 1 denotes a turret punch press machine frame;
Lower turret (disk), 4 is a punched ram,
Reference numeral 5 denotes a processing table, and reference numeral 6 denotes a work carriage having a work clamp.

7 is a conventional shot pin for holding each position after the upper / lower turret 2/3 position indexing,
8 is a shot pin specially provided on one side of the lower turret 3 according to the present invention.

(B) In FIG.
Is setably mounted via an oil seal 11 in a shot pin engaging hole 3a provided on one side surface of the lower turret 3, and a pipeline 12 communicating with the shot pin 8, the lower turret 3 and the die holder 9 is provided. An oil mist ejection hole 12a at the end portion is opened in the swarf discharge hole 10 of the die holder 9 which is formed.

In the pipeline 12 of the special shot pin 8, an air source 13 of the oil mist M, a filter 14, a regulator 15 set to a predetermined pressure, for example, 5 kg / cm ² , and a lubricating oil lubricator are provided at predetermined distances. 16 and a solenoid valve 17 and the like are connected in series and configured to supply an oil / air medium via a conduit 18.

(Operation) The ejection of the oil mist M is turned on when the solenoid valve 17 detects the signal for setting the shot pin 8, and passes through the shot pin 8, the lower turret 3, the die holder 9, and the die holder 9. The oil mist M is ejected toward the workpiece W from the ejection hole 12a.

As a result, lubricating oil adheres to the inner periphery of the hole of the work W or the die D, and after punching, the oil adheres to the punch P to improve the lubricity between the punch P and the die D.
Welding can be prevented. In addition, the life of both molds is improved, and there is no fear of interfering with stamped scraps as in the conventional example.

[0018]

As described above, according to the present invention,
During the punching process through a specially designed shot pin, oil mist is sprayed through the shot pin, the lower turret, and the die holder to the lower part of the work without interfering with the chipping of the equipment. To prevent welding and the like and contribute to extending the life of the mold.
