BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet metal working machine, and more particularly, to a scratch on a material (work) by using a rotating brush on a center table on which a plate-shaped work is placed and supported. The present invention relates to a sheet metal processing machine for reducing friction or sliding resistance.

[0002]

2. Description of the Related Art Conventionally, a sheet metal working machine such as a punch press or a shearing machine operates a work clamp provided on a carriage supported on a carriage base movable in the X-axis direction so as to be movable in the X-axis direction. In many cases, one end of a work is clamped to move and position the work.

This carriage base has both ends on a side table, and the work positioned in the X-axis direction is moved together with the carriage to a processing section (processing position) of a sheet metal processing machine by a predetermined distance (Y-axis movement). (Movement) to perform predetermined processing. At this time, the position of the clamp can be adjusted each time according to the work size.

[0004] Further, a large number of spherical free bears are incorporated in a center table fixed to a sheet metal working machine and side tables on both sides of the center table, and a work is slid on the free bears. Instead of this free bear,
Artificial turf or nylon brushes may be used.

[0005]

[Problems to be Solved by the Invention] By the way, the free bear is usually a steel ball, and is not so effective for a material such as aluminum and stainless steel, whose surface is easily damaged.
There is also a problem that dents are formed. There is also a problem that noise such as resonance noise between the work and the free bear, and sound due to the flapping of the work is generated.

[0006] The artificial turf or the nylon brush provided on the table may cause scratches on a soft work surface such as an aluminum material. The noise is quieter than in the case of the free bear, but the processed end face of the work and the burr of the hole get caught on this artificial turf or brush,
There are problems such as a shortened life.

[0007] An object of the present invention is to solve the above-mentioned problems by making it easy for a work that is easily scratched to slide on a center table, thereby reducing abrasion, catching or sliding resistance on the work surface. An object of the present invention is to provide a sheet metal working machine capable of reducing generation of noise and enduring long-term use.

[0008]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention provides a carriage base provided so as to be movable in a Y-axis direction which approaches and separates from a processing position for processing a plate-shaped work. In a sheet metal working machine provided with a carriage having a work clamp capable of holding the work freely in an X-axis direction orthogonal to the Y-axis, a center table for mounting and supporting the work is provided. A plurality of brush rollers capable of supporting the work are rotatably provided around a horizontal axis, and the movement of the work and the rotation of the brush roller are synchronized.

The side tables 29 and 29A are integrally connected via a carriage base 31 having one end extending in a direction orthogonal to the moving direction. The carriage base 31 is connected to the carriage base 31. A carriage 33 slidable in the same direction as the longitudinal direction is mounted. An appropriate number of work clamps 35 capable of holding an end of the work W are mounted on the carriage 33 so as to be movable and fixed in the moving direction of the carriage 33.

An X-axis ball screw 37 for mounting the carriage 33 is provided in the longitudinal direction of the carriage base 31, and an X-axis drive motor 39 is linked to the ball screw 37 via a transmission member. I have.

When the X-axis drive motor 39 is driven by the above configuration, the carriage 33 is moved in the front-rear direction (X-axis direction) via the X-axis ball screw 37. One end of the carriage base 31 is interlocked with the Y-axis drive motor 41, and the carriage base 31 is moved in the left-right direction (Y-axis direction) by driving the Y-axis drive motor 41. . Therefore, the work W held between the work clamps 35 is movable in the X-axis and Y-axis directions.
