Abstract

PURPOSE:To prevent the generation of a scratch due to abutting by arranging many brushes supporting the metal sheet on the metal sheet mounting surface of work table. CONSTITUTION:In a metal machine of a punch press or a laser beam machine, etc., many brushes 20 projecting from a mounting surface are dispersively arranged on the metal sheet mounting surface of a work table 2 and a lower turret 18, and the metal sheet W is supported with these brushes 20 on the work table 2 and the lower turret 18. And the metal sheet W is, for example, a part is held with a work holder, and the feed is executed with the movement of this work holder. In such a way, without generating a scratch grid on the metal sheet due to abutting, the movement on the work table can be smooth executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material processing machine such as a turret punch press, a shearing machine and a laser processing machine.

[0002]

2. Description of the Related Art In a conventional plate material processing machine of this type, in order to smoothly move the plate material on the work table, as shown in FIG.
Was provided.

[0003]

However, in the structure in which the plate material W is supported by the balls 41 and the plate material W is moved as described above, when the plate material W is a thin material or a decorative plate, the sliding contact with the ball 41 is performed. This causes a problem that the surface of the plate material W is scratched.

An object of the present invention is to provide a plate material processing machine capable of smoothly moving a plate material on a work table without damaging the plate material by sliding contact.

[0005]

According to the plate material processing machine of the present invention, the plate material mounting surface of the table is provided with a large number of brushes protruding from the mounting surface and supporting the plate material.

[0006]

According to this structure, since the plate member is moved by being supported by the brush projecting on the table, it is possible to prevent the plate member such as a thin object or a decorative plate from being scratched by sliding contact.
Moreover, the plate material can be fed smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. FIG. 3 shows a perspective view of a turret punch press which is a plate material processing machine of this embodiment. Base frame 1
A work table 2 on which the plate material W is placed, and a work feeding device 3 for moving the plate material W back and forth (Y axis direction) and left and right (X axis direction) on the work table 2 are provided.
A C-shaped frame 4 is continuously formed on the rear portion of the base frame 1, and a punch position P is formed in the C-shaped frame 4.
An upper turret 17 in which a plurality of punch tools to be pushed down by the ram 5 of FIG. 4 are arranged, and a punch drive mechanism (not shown) for driving the ram 5 up and down are provided.

The work table 2 is composed of a central fixed table 6 fixed to the base frame 1 and slide tables 8 and 9 on both sides which move back and forth on a rail 7. The fixed table 6 includes a front fixed table 6a and a rear fixed table 6b as shown in a plan view in FIG.
A lower turret 18 is rotatably provided in the middle of the rear fixed table 6b. Lower turret 18 is upper turret 17
A plurality of dies 19 corresponding to the respective punch tools are arranged.

The work feeding device 3 is a carriage which is integrally formed with the slide tables 8 and 9 on both sides and moves back and forth.
The carriage 11 has a cross slide 12 mounted thereon. The carriage 11 is driven back and forth by the base frame 1
It is performed by a feed screw (not shown) provided on the. The cross slide 12 is driven forward and backward by a servo motor 16 provided on the carriage 11 via a feed screw 14 and a ball nut 15 (FIG. 3) to the left and right.
A plurality of work holders 13 for holding are attached side by side.

The work table 2 and the lower turret 18
On the plate material mounting surface, a large number of brushes 20 projecting from the mounting surface are dispersedly arranged, and the plate materials W are supported by the brushes 20 on the work table 2 and the lower turret 18.

FIG. 1 shows a rear fixed table 6 shown in FIG.
It is sectional drawing which expands and shows the II cross section of the part which straddles from the lower turret 18 to b. The rear fixed table 6b is composed of a lower plate member 22 fixed to the frame 25 and an upper plate member 21 installed on the lower plate member 22 via a spacer (not shown). An upper plate member 24 is installed on the lower turret 18 via a support column 23 in a floating state.

A large number of holes 26 through which the brush 20 projects are formed in the upper plate members 21 and 24 in a dispersed manner, and the brush 20 is attached to the upper plate members 21 and 24.
Is provided so as to project from the upper surface of the substrate by a predetermined height. As shown in the perspective view of FIG. 2, the brush 20 comprises a circular base 27 with ring-shaped resin brush bristles 28 planted on the upper surface thereof. These brushes 20 are lower plate materials of the rear fixed table 6b.
It is fixed to the brush mounting member 24a of the upper plate member 24 with the screw 29 on the turret 18 on the turret 18.

Although FIG. 1 shows the installation structure of the brush 20 on the plate mounting surface of the rear fixed table 6b and the lower turret 18, the front fixed table 6a and the slide tables 8 and 9 are shown.
In the same manner, the brush 20 is installed in the same manner as the installation structure of the rear fixed table 6b.

In the turret punch press having this structure, the plate material W on the work table 2 is gripped by the work holder 13 and fed to the front, rear, left and right by the movement of the work holder 13. At this time, the plate material W on the work table 2 has a large number of brushes 20 protruding from the work table 2 and the lower turret 18.
Since it is supported by and moves, even in the case of a thin object, a decorative plate, etc., it moves smoothly without causing scratches due to sliding contact.

In the above embodiment, as the brush 20, the ring-shaped brush bristles 28 are planted on the circular base 27, but the present invention is not limited to this. For example, as shown in a perspective view in FIG. A ribbon-shaped brush 31 in which brush bristles 28 are planted on the entire square base 30 may be used.

[0016]

In the plate material processing machine of the present invention, since a large number of brushes protruding from the mounting surface and supporting the plate material are provided on the plate material mounting surface of the table, the plate material such as a thin material or a decorative plate is placed on the table. Even when it is moved by, the plate material can be smoothly moved on the table without being scratched due to the sliding contact.
