Incidentally, the X1-axis carriage (59),
Clamps (57, 69) for holding the plate-shaped work W are attached to the X2-axis carriage (71).

The ram (31) for hitting a plurality of punches is provided so as to be movable and positionable in the U and V axis directions parallel to the X and Y axes so that an arbitrary punch can be selected and hit. .

A method of punching in the punching machine (1) having the above configuration will be described.

First, a die (punch, die) to be used is selected. Next, the punch block (15) and the die block (13) are moved and positioned so that the Y coordinate of the selected mold coincides with the Y coordinate of the position where the workpiece is to be processed, and at the same time, the X coordinate of the processing position of the workpiece is changed. Move the X1-axis carriage (59) to a position corresponding to the X coordinate of the positioned mold.
Use to move and position. Next, the ram (31) is moved and positioned above the selected mold, and a punch is performed by hitting a punch.

Normally, these positioning operations are performed by NC
It is executed simultaneously under the control of the device.

As described above, the X1-axis carriage (5
9), processing is performed from the left side of the work W, and when processing of the workable area on the left side of the work W is completed, the left side of the work W is gripped by the X2-axis carriage (71). The processing area on the right side of the workpiece is processed by the shaft carriage (71). The work W that has been processed is carried out from the rear table (45) side.

Next, from the long material, a large number (24 in the illustration)
The method for processing the individual products will be described with reference to FIGS. 11, 12, and 13. FIG.

FIG. 11 (a): The right side of the plate material is clamped by two clamps (57) on the left side of the X1-axis carriage (59) to form a hole. The inside of the left diagonal line is X
This is a workable area by the uniaxial carriage (59).

FIG. 11B: Trimming unnecessary portions on the outer periphery.

11 (c) and 11 (d): The portion where the hole processing has been completed is cut and separated into product units by overtaking, and is carried out from the left rear table (45) side.

FIG. 12E: X2-axis carriage (71)
The left side of the plate is clamped by two right side clamps (69), and the clamp of the X1-axis carriage (59) is released. (Re-clamping) FIG. 12 (f): The remaining machining area is drilled using the X2-axis carriage (71).

FIGS. 12 (g) to 12 (i) and FIG.
(J): The portion where the hole processing has been completed is cut and separated into product units by overtaking, and is carried out from the left rear table (45) side.

FIG. 13 (k): Pulling out a product holding frame (skeleton) from between the tool blocks (punch block (15), die block (13)).

FIG. 13 (l): The clamp is released, and the skeleton is carried out from the left rear table (45).

According to the conventional processing method as described above, a large number (24 in the illustration) of the long material can be cut and separated.

[0020]

However, when a large number of products are processed from a long material using the above-mentioned conventional punching machine, the products are finally cut and separated from the plate using an X2-axis carriage. Sometimes, a "U" -shaped product holding frame for holding a part to be a product on a plate is required.

The above-mentioned product holding frame eventually becomes waste material (skeleton). Large waste material deteriorates the yield of the product, and the discharge and disposal of the waste material are troublesome.
In the case of a thin plate, there is a problem that the rigidity of the product holding frame is small and the plate cannot be held with high accuracy, so that the positioning accuracy is deteriorated.

In the conventional punching machine described above, when the X1-axis carriage (59) and the X2-axis carriage (71) are at the closest positions, the distance L between the clamps is dead zone. It becomes the minimum dimension in the X-axis direction of the plate material that can be processed without any.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a plate material which can process a large number of products from a long material with a good yield and can easily treat waste materials. An object of the present invention is to provide a processing apparatus and a plate material processing method.
