JP4382916B2 - Air blow device for work bottom surface of turret punch press - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air blowing device for a lower surface of a work of a turret punch press.
[0002]
[Prior art]
In the conventional turret punch press, for the lubrication and cooling of each die punch / die on each upper / lower turret (disc),
Air blow (blow) from the upper surface of the workpiece, and oil mist spray of the pinpoint rubbler from the lower surface of the workpiece,
Each air blowing method is performed.
[0003]
In FIG. 2, the schematic of the pinpoint rubbler of the air blow apparatus from the die | dye D lower part of the latter workpiece | work W lower surface is shown. 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 the upper part thereof, and 10 denotes a scrap discharge hole communicating with an opening of a die (not shown). Indicates.
[0004]
A ring-shaped device 20 as an air blow device of the pinpoint rubbler is an annular body of a hollow tube, and has a plurality of oil mist injection holes 21 on its inner diameter, and is in contact with the discharge hole 10 to be removed. The oil mist is supplied through an air source (not shown), a regulator, a lubricator, and a conduit, and the oil mist M is injected and supplied from each of the injection holes 21 to the upper punched portion in the direction of the arrow. Thus, it is configured to perform the desired lubrication and cooling.
[0005]
[Problems to be solved by the invention]
However, in the conventional configuration as described above, since the ring-shaped device 20 is disposed in the discharge hole 10 of the lower turret 3, when the drop (scrap) falls, the ring device 20 is caught on the ring. There was a possibility of clogging and impairing workability.
[0006]
The present invention has been made in view of the above-described situation, and an object thereof is to provide a space-saving and effective air blow system on the lower surface of a workpiece for solving the above-described problems.
[0007]
[Means for Solving the Problems]
For this reason, in this invention, it is going to achieve the said objective by providing the workpiece lower surface air blow apparatus of the following turret punch press.
[0008]
In the turret punch press, the turret and die holder are respectively drilled in the vicinity of the die indexed directly below the ram to be punched and through a shot pin conduit specially provided on one side of the lower turret. A turret punch press characterized in that it is configured to inject through a solenoid valve from a predetermined oil mist source from an oil mist outlet opening in an inner surface of a die discharge hole of the die holder. Air blow device for work bottom surface.
[0009]
[Action]
With the above-described configuration of the present invention, the lubricity and cooling performance of the punch / die can be improved to prevent welding, etc., the life of the punch / die can be improved, and the flow of the scrap discharge holes can be hindered. Therefore, there is no fear of a decrease in work efficiency.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail based on an example with reference to the drawings.
[0011]
【Example】
1A and 1B are explanatory views of the configuration of an embodiment according to the present invention, in which FIG. 1A is a schematic diagram of the overall configuration and FIG.
[0012]
(Constitution)
(A) In the figure, 1 is a machine frame of a turret punch press, 2/3 is an upper / lower turret (disc), 4 is a punching ram, 5 is a processing table, and 6 is a work carriage having a work clamp. Indicates.
[0013]
7 is a conventional shot pin for holding each position after indexing the upper / lower turret 2/3 position, and 8 is a shot pin specially provided on one side of the lower turret 3 according to the present invention. .
[0014]
(B) In the figure, a special shot pin 8 is attached to a shot pin engaging hole 3a provided on one side surface of the lower turret 3 through an oil seal 11 so as to be settable. 9, pipe lines 12 communicating with each other are formed, and an oil mist ejection hole 12 a at the terminal portion is opened in the discharge hole 10 that is removed from the die holder 9.
[0015]
The pipe 12 of the special shot pin 8 includes an oil source 13 for the oil mist M, a filter 14, a regulator 15 set to a predetermined pressure, for example, 5 kg / cm ² , an oil lubricator 16 for lubrication, and an electromagnetic wave. A valve 17 or the like is connected to the series so that an oil / air medium is supplied through a conduit 18.
[0016]
(Function)
The oil mist M is ejected when the electromagnetic valve 17 detects the signal for setting the shot pin 8 and is turned on. Mist M spouts toward work W.
[0017]
Thereby, lubricating oil adheres to the inner periphery of the hole of the workpiece W or the die D, and after punching, the oil adheres to the punch P, improving the lubricity between the punch P and the die D, and preventing welding. In addition, the service life of both molds is improved, and there is no fear of interfering with the punched scrap as in the conventional example.
[0018]
【The invention's effect】
As described above, according to the present invention, oil mist is sprayed to the lower part of the workpiece through the shot pin, the lower turret, and the die holder without interfering with the apparatus during the punching process through the special shot pin. Therefore, the lubricity of the upper and lower molds can be improved, welding and the like can be prevented, and the mold life can be extended.
