Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view illustrating a processing apparatus of the present invention, FIG. 2 is a plan view of the processing apparatus, and FIG. 3 is a plan view and a front view of a mold fixing jig. In FIG. 2, reference numeral 1 denotes a processing table, and the adjustment table 2 is fixed to the processing table 1. A mold fixing jig 3 is mounted on the adjustment table 2. The adjustment table 2 includes an outer frame 2 a fixed on the processing table 1, a movable body 2 b movable in an insertion direction of the mold (X direction), and a direction orthogonal to the insertion direction of the mold (Y direction). The movable members 2b and 2c are adjusted in the X and Y directions by position adjusting screws 2d and 2e, respectively. The moving bodies 2b and 2c receive and mount the mold material fixing jig 3,
The mold fixing jig 3 is adjustable in the XY directions.
The XY directions refer to the vertical directions orthogonal to each other on a plane on the processing table 1.

The position of the mold fixing jig 3 is adjusted by moving the adjustment moving body 2a in the X and Y directions via the position adjustment screws 2b and 2c. Therefore, when the processing dimension is slightly changed, the dimension can be changed by changing the mounting position of the fixing jig 3, and it is not necessary to rework the jig. The fact that the position of the mold fixing jig 3 can be adjusted is also advantageous in the case where rotating teeth of a cross cutting mechanism described later are worn.

The mold fixing jig 3 includes left and right side portions 3 erected so as to face the lower surface portion 3a placed and fixed on the adjustment table 2.
The upper side is open from b and 3c. A receiving portion 3d corresponding to the cross-sectional shape of the mold A is formed from the opposing surfaces of the side surfaces 3b and 3c and the upper surface of the lower surface 3a. The rear end of the side portion 3b extends further rearward than the rear end of the side portion 3c, and a projection is formed on the inner surface of the rear end.

The projecting piece constitutes a contact portion 3e for positioning the mold material A by contacting the edge of the mold material A inserted into the receiving portion 3d. The contact part 3e is formed so as to face the insertion movement path of the mold material A, and the receiving part 3d is formed.
A part of the end portion of the shape material A inserted and received in the contact portion 3e
, So that the further movement of the mold material A is restricted. Note that the contact portion 3e is a protrusion whose thickness corresponds to the thickness of the mold material A. Further, the contact part 3e may be movable so that the contact position can be switched in several stages.

At the time of positioning in which the end of the mold A is in contact with the contact portion 3b, the corner on the side 3c of the end of the mold A is exposed. The orthogonal cutting means 4a, 4b are located. The cutting means 4a and 4b which are orthogonal to each other are provided with rotary saw teeth, and are configured so that the cutting means 4a and 4b rotate and descend to cut the corners at the ends of the mold material A.

The mold fixing jig 3 further has fixing means 5, and the fixing means 5 is configured to fix the mold A when the mold A is in the positioning state. The fixing means 5 is mounted on the upper side of the fixing jig 3, and its holding portion 5 a is always separated from the molding material A by a spring.
Of the pneumatic clamp 6 when the end of the
As a result, the pressing portion 5a moves downward, and presses and fixes the mold A in the receiving portion 3d of the fixing jig 3.

Receiving part 3 corresponding to the cross-sectional shape of mold A
“a” does not necessarily have to be the same as the entire cross-sectional shape of the mold material A, and may be any shape that can restrain the side surface of the mold material A when the mold material A is inserted. Further, the fixing jig 3 may be set by stacking the materials in two stages (see FIG. 4). By doing so, it is possible to cut a large number of mold members in one step.

FIG. 5 shows another embodiment of the mold fixing jig 3. As shown in FIG. In this device, a part of the jig is made to be approximately square and freely rotatable by 90 degrees so that it can correspond to a plurality of molds A1, A2, A3, A4, and A5, each of which has a different cross section. An escape space is provided.

More specifically, the fixing jig 3 has a jig body 30 having an insertion portion 30a having a substantially square cross section and a substantially square shape having a cross section. The movable jig 31 is detachable. Movable jig 31
Each of the side surfaces A, B, C, and D has a different mold material A1,
A relief space corresponding to A2, A3, A4, and A5 is formed, and the receiving portion 30b of the jig main body 30 and the selected side surface of the movable jig 31 are integrated with each other to substantially have the cross-sectional shape of the mold. The receiving portion has the same shape.

Side surfaces A, B, C, D of the movable jig 31
By selecting a surface and inserting it into the insertion portion 30a of the jig main body 30, it is configured to correspond to a mold having a different shape. Further, a fitting groove 31a is formed on the side A and the side D of the movable jig 31, and a fitting groove 31b is formed on the side B. The fitting jig 30 is fitted on one side of the insertion portion 30a of the jig main body 30. Projection 3
The movable jig 31 can be set on the jig main body 30.

This configuration can be applied not only to a fixing jig for a cross-cutting machine but also to a stamping die and the like. In addition, by using in combination with the movable stopper described above,
It is possible to cope with processing of more mold materials.

[0018]

According to the present invention, since the end corners of the die are cut by using a cross cutting mechanism instead of the conventional press, the die is adapted to the shape of each die as in press working. It is not necessary to fabricate the material, and the cutting process is more flexible than the pressing process. According to the cross-cutting mechanism, highly accurate processing can be performed, and if the die members are set one upon another, the end corners of a plurality of die members can be cut at the same time. The larger the cut-off portion, the shorter the processing time as compared with press processing. Further, even a simple pipe-shaped cut-off as shown in FIG. 1 requires two steps in the case of press working. However, this working method can be performed in one step, and the working time can be reduced.
