Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device such as a press machine. More specifically, the present invention relates to a processing device with an improved method of fixing a mold.

Hereinafter, the case of positioning and fixing the bow and die of a press machine will be explained as an example.

Conventionally, when fixing an arrowhead die to a press machine, press brake, etc., the upper die and lower die are engaged while visually adjusting the alignment in the X@ and Y axis directions, and the die is fixed in the engaged state. The method is bamboo. However, this method requires a skilled skill to simultaneously adjust both the X and Y axes for meshing. Moreover, since it is fixed with bolts, it takes a lot of time to tighten it. Furthermore, this bolt tightening work is manually performed when the press machine, press brake, etc. are at the bottom dead center, which poses a problem of creating many dangers.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a processing device that solves the problems of the conventional fJ+JAt device and can quickly and efficiently position and fix a processing table such as a mold.

Hereinafter, one embodiment of the present invention will be described in detail using the drawings. FIG. 1 is a perspective view of a mold fixing part of a press machine using an embodiment of the present invention, and FIG. 2 is a sectional view of the mold holding stand.

In the figure, reference numerals 1 and 2 denote the bases of a mold holding stand 6, which are integrally fixed to the processing machine main body 4 with screws 5. Furthermore, protrusions 3a and 3b are provided at both ends of the upper surface of the mold holder B at intervals of the same width as the width a of the mold 6. Thereupon, the mold 6 is guided on the holding base 6 by the projections 6a and 6b, and can slide in the direction shown by the arrow. Note that 6a is a processed groove, for example, when pressing down the arrow string 8 provided on the whole body side of the iron plate 7 (indicated by the two-point button line) and folding it 111 places (the state in which the iron plate 7 is folded 11 places apart is shown at two points) Chain line 7a
), which is adapted to engage with the arrow tip 8a of the arrow string 8, and is V-shaped.Furthermore, at both ends of the holding base 60, there are horizontal through holes 10 in the vertical direction 1α, with projections 3a and 6bK appearing. is provided. Further, a vertical through hole 11 is provided vertically downward with respect to the horizontal through hole 10. -J Ah,
In other words, the holding table 6 is provided with a T-shaped through hole. The base 2 is provided with a cylinder S that is perpendicular to the through hole 11. This cylinder 8 is fixed to the base 2 with a screw 9a.

A plunger 9 is provided within the cylinder S, which can be moved up and down by air pressure. The plunger 9 passes through a vertical through hole 11 and reaches a horizontal through hole 10 for vertical movement, and a guide piece 12 is attached to the tip located within the horizontal through hole 10. Note that this guide piece 12 has an elliptical shape with straight side surfaces 12a and 12b. Further, it is desirable that the cylinder S is prevented from air leakage by using, for example, a liquid gasket.

Therefore, the holding stand 6 is guided by the side surfaces 12a and 12b of the guide piece 12 and is movable in the horizontal Y-axis direction (in the direction of arrow C) (the state in which the holding stand 6 is moved is shown by a two-dot chain line 6C).

Therefore, the metal fitting 6 mounted on the holding stand 6 is moved by sliding on the holding stand 6, avoiding the protrusions 3a and 3bK.
The position in the horizontal X-axis direction can be adjusted, and by moving the holding base 6 along the guide piece 12, the position in the horizontal Y-axis direction can be adjusted.

Reference numeral 13 denotes a lever, and by operating this lever 16, the plunger 9 in the cylinder S serving as an auto-clamping means can be moved up and down using air pressure. In this embodiment, by keeping the lever 15 in the state shown by the solid line, the plunger 9 is positioned upward (
In the state shown in FIG. 2), the guide piece 12 does not press and fix the holding table 6, and the holding table 6 is movable in the direction of arrow C.

Then, by tilting the lever 16 to the position shown by the dotted line (indicated by the figure number 13a), air flows from the air source A through the tube T1 and into the upper part of the cylinder S, and this air pressure causes air to flow into the cylinder S. is lowered, the lower surface 12c of the guide piece 12 comes into pressure contact with the lower surface 10a of the horizontal through hole 10, and the holding table 6 is fixed to the base 2.

At this time, the air below the cylinder S is exhausted from the tube T2. Note that by operating the lever 16, the plungers 9 at both ends are operated simultaneously. Therefore, in this embodiment, the holding stand 5 can be fixed to the base 2 simply by operating a lever. To further release the fixation, return the lever 13 to the solid line position, and the air in the upper part of the cylinder S will be removed through the tube T4, the air will be guided through the tube 'f2, and the plunger 9 will rise to establish a pressure-welded state. Unraveled. Further, reference numeral 14 is attached to a plate to further secure the base 1 to the main body 4.

Next, using this embodiment, a case will be described in which a processing operation of bending the iron plate 7 from a predetermined location is performed.

First, the ■-shaped processing groove 6a of the mold 6 is positioned at a position where it engages with the arrow tip 8a of the arrow string 8, which is vertically movably mounted on the main body side.

To do this, the lever 16 is moved to the solid line position so that the holding table 13 is movable in the direction of arrow C. Then, the operator grasps the holding base 6 and aligns the horizontal through hole 10 with the side surface 12a of the guide piece 12.
12b, the holding stand 6 is moved in the direction of arrow C, and moved in the horizontal Y-axis direction to a position where the processed groove 6a substantially corresponds to the arrow tip 8a. Next, when the arrow string 8 is gradually lowered to the preset bottom dead center, the cylinder S is unclamped.
In this state, the holding table 6 slides in the horizontal Y-axis direction while being held by the holding table 6 to the correct engagement position due to the self-aligning action of the V-groove shape of the machined groove 6a.

Therefore, when the arrow string 8 reaches the bottom dead center, the alignment of the arrow string 8 and the processed groove 6a is completed. In this state, the holding base 6 can be fixed to the pace 2 by lowering the lever 16 to the position shown by the two-dot chain line and clamping the cylinder S. Next, adjustment in the horizontal
3b and slide it to the position where the processing groove 6a is on the same level as the arrow tip 8a.
++It is possible to adjust the force direction to fit HIAI. The mold 6 is now filled with water j11. The position with respect to the X-axis and Y-axis is determined.

Next, the holding position of the abutment plate 15 held by the abutment plate fixing device i1 (not shown) is determined in accordance with the center width of the iron plate 7.

Therefore, the iron plate 7 to be bent □ is placed between the mold 6 and the arrow tip 8.
Insert the iron plate 7 until its tip hits the hole 15 between the holes a and place the iron plate 7 on the upper surface of the mold 6 at that position.
This state is shown in FIG. 1).

Then, by operating an arrow string lever (not shown), the arrow string 8 is lowered a sufficient distance, and when the arrow tip 8a engages with the machined groove 6a, the iron plate 7 is bent (the bent iron plate is indicated by a double-dot chain 17a).

Therefore, according to this embodiment, the mold 6 can be positioned with respect to the arrow string 8 quickly, easily, and reliably. Therefore,
You can replace it with another mold, position and fix several different molds on the holder, or even install multiple different molds on the holder and select the required mold according to the processing conditions. It is also possible to quickly and easily position the arrow to a position corresponding to the arrow string.

Further, by taking out the iron plate that has been bent and subsequently positioning and placing a new iron plate on the mold 6, continuous work at T51 can be easily performed.

In the above embodiment, an example of a cylinder using pneumatic pressure was shown as an auto-clamping means, but the invention is not limited to this, and for example, an air pressure cylinder, a solenoid cylinder, etc. may be used.

In addition, as an example of a processing table such as a mold, in this embodiment, only an example of a mold used for bending an iron plate is shown, but the present invention is not limited to this. Of course, it also includes those used for drilling or grinding, etc. In addition, the workpiece is not limited to metal plates such as iron plates and aluminum plates.
For example, it may be made of resin or the like.

As described above, the present invention provides a processing device that can easily and quickly position a mold.
