BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sizing ruler, and more specifically, a plurality of stages of sizing rulers provided on a side for supplying a plate material to a plate material processing machine such as a shearing machine, a bending machine, a press brake or the like. It is about.

[0002]

2. Description of the Related Art Conventionally, a fixed-size ruler used in the above-mentioned plate material processing machine, which is provided on the side for supplying the plate material, is called a front gauge, and the plate material to be supplied is manually fed once over the processing line. Then, pull it back and press it against the sizing ruler set at two places on the left and right to position the tail end of the plate material. Since the center of gravity is located as far as possible on the long side with respect to the rotating shaft provided in the vicinity of the obtuse angle portion and the short side is directed to the machining line,
When pushing the plate material toward the processing line on the material feeding table, the short side is pushed by the plate material, and by the above rotation, it sinks lower than the material feeding table surface to allow the plate material to enter, and the long side after passing the plate material. Due to the center of gravity on the side, the short side of the sizing ruler protrudes above the feeding table surface again, and when the above plate is returned, the tail end of the plate comes into contact with the short side of the sizing ruler for positioning. Is done.

[0003]

Conventionally, the rotating sizing ruler as described above is provided on the left and right sides of the material feeding table.
A pair of rulers was positioned and fixed manually or electrically in the groove of the book. Therefore, for high-mix, low-volume production, the position of the ruler is frequently changed, resulting in a reduction in work efficiency.

[0004]

In view of the conventional problems as described above, the present invention provides a guide abutment connected to a table of a processing machine by extending in a direction orthogonal to a processing line of the processing machine. , A rear end of a sliding member slidably supported on a guide abutment is provided so as to be movable to a position close to the processing line,
A work contact portion for contacting the work is provided on the sliding member,
A driving device controlled numerically is provided, and the driving device and the sliding member are interlockingly connected to each other so that the moving and positioning of the sliding member is numerically controlled.

[0005]

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sizing ruler, and more particularly to a sizing ruler provided on the front side of a plate material processing machine such as a shearing machine, a bending machine or a press brake.

[0002]

2. Description of the Related Art Conventionally, a sizing ruler provided on the front side of a plate material processing machine as described above is called a front gauge, and a plate material to be supplied is manually fed once over a processing line and then returned to the left or right. The front side of the plate is pressed against the work contact portions of the sizing rule set in two places to position the plate. Therefore, the work contact portions of the left and right sizing rulers have, for example, an obtuse triangular shape having a long side and a short side, or a bell crank shape, and the long side with respect to the rotating shaft provided near the obtuse angle portion. The center of gravity is located as far as possible, and the short side is directed to the machining line. Therefore, when pushing the plate material toward the processing line on the material feeding table, the short side is pushed by the plate material and sinks lower than the surface of the material feeding table to allow the plate material to enter, and the long side after passing the plate material. Due to the center of gravity on the side, the short side again projects above the material feeding table surface, and at the time of returning the plate material as described above, the front side of the plate material is brought into contact with the short side of the work contact portion to be positioned. ..

Conventionally, the sizing ruler having the above-mentioned structure has a pair of rulers in two grooves in the front-rear direction provided on the left and right guide abutments connected to the front side of the material feeding table. Is positioned manually or electrically. Therefore, when the plate material becomes relatively narrow, it was difficult to perform positioning. In addition, positioning was difficult even when the plate material was relatively large.

[0004]

The sliding member 3 is provided with a work contact portion 1 for contacting a work, and a driving device 7 that is numerically controlled is provided, and the driving device 7 and the sliding member 3 are provided.
Since it is configured so that the sliding member 3 is moved and positioned in a numerically controlled manner by interlocking with and linked with each other, it can be easily retrofitted to a conventional processing machine. Further, since the rear end of the sliding member 3 can be moved to a position close to the machining line 9, accurate positioning can be performed even if the plate material is short. Furthermore, since the sliding member 3 is moved and positioned numerically, the efficiency of positioning the plate member is improved. That is, since the moving and positioning of the sliding member 3 can be performed numerically, the moving and positioning can be performed quickly and easily, and the working efficiency is improved.

Further, since the front end portion of the sliding member 3 is provided so as to be able to protrude largely from the guide support 5 forward, even if the overall structure is small, it extends over a large range longer than the length of the guide support 5. The plate member can be moved and positioned.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. That is, it can be implemented in other modes than the above embodiment by making appropriate design changes. For example, it is possible to attach a plate material by attaching a magnet or a vacuum device to the angular sliding member, and further, contact the work contact parts with a contact device such as a switch device that detects the contact of the plate material. It is also possible to adopt a configuration in which a detection device is provided. With the above configuration, the sliding member and the plate material can be moved integrally, and the processing can be performed after it is confirmed that the plate material is in contact with each work contact portion.
