Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame forming device for forming a frame forming a panel.

[0002]

2. Description of the Related Art In recent years, various panel bodies have been provided which are formed by attaching face plates to the front and back surfaces of a frame body formed in a square shape. The frame bodies constituting these panel bodies are formed into a predetermined shape, for example, a square shape by connecting the ends of the frame material 14 formed in a U-shaped cross section so as to fit each other. It is like this.

When forming the frame body, since the face plates are attached to the front and back surfaces of the frame body, the frame members 14 are connected to each other at the end portions of one of the frame members 14. As shown in FIG. 9, drawing processing for fitting the end portion of the other frame member 14 is performed, and the end portion of the other frame member 14 is fitted to the stepped portion 13 that is lowered by one step formed by this drawing processing. Then, the frame body is formed by joining the ends of the frame member 14 by spot welding b as shown in FIG.

[0004]

However, in the conventional example as described above, it is necessary to temporarily assemble the separate frame members 14 into a predetermined shape when forming the frame body.
At this time, assembling the separately formed frame members 14 is complicated, and since each frame member 14 is separate, temporary assembly before performing spot welding b is performed. Since positioning is difficult, there is a problem that molding takes time and is apt to be uncertain.

An object of the present invention is to solve the above-mentioned problems, and it is possible to easily form a frame material into a predetermined shape without trouble, and to easily form a frame body. An object of the present invention is to provide a body shaping device.

[0006]

According to the present invention, in order to achieve the above object, a pusher which is movable along the longitudinal direction of the arm 2 is provided on the upper surface of an elongated arm 2 having a shaft support 1 at one end. A die 3 is provided, and a working die 5 is formed on the other end side of the upper surface of the arm 2 by providing a movable die 4 which is movable in the longitudinal direction of the arm 2 so as to be movable toward and away from the pressing die 3. A contact surface 6 for angling the workpiece a placed on the arm 2 at a predetermined angle is formed on the opposing end surfaces of the pressing die 3 and the contact die 4, and is rotatable in a horizontal plane by the shaft support 1 being pivotally attached. Thus, at least three or more working arms 5 are arranged side by side on the base 7 so that

[0007]

Thus, the work a can be bent simultaneously at a plurality of positions by the plurality of work arms 5 arranged adjacent to each other, and one work a can be processed by the plurality of work arms 5. At the same time, the polygonal frame body can be molded in a short time by bending.

[0008]

The present invention will be described below in detail with reference to the illustrated embodiments. The frame forming device has a base 7 as shown in FIG.
At least three work arms 5 are arranged adjacent to each other on the upper side. In the illustrated embodiment, the six working arms 5 are arranged next to each other, but the number may be 6 or more or 6 or less.

As shown in FIG. 2, the working arm 5 has a push die 3 which is movable along the longitudinal direction of the arm 2 on the upper surface of a long arm 2 having a shaft supporting portion 1 at one end. On the other end side of the upper surface of the above, a main body is formed by providing a pressing die 4 which is movable along the longitudinal direction of the arm 2 so as to be able to approach and separate from the pressing die 3. The arm 2 is formed to have a U-shaped cross section with an open upper surface, and a drive screw 9 that is rotationally driven by a drive motor 8 provided at the other end of the arm 2 is housed in the internal space. The lower part of the pad die 4 is screwed onto the drive screw 9, and when the drive screw 9 is rotated by the drive motor 8, the pad die 4 moves in the longitudinal direction of the arm 2 in association with the rotation of the drive screw 9. It is designed to move along.

A cylinder 10 is arranged at one end of an arm 2 provided with a shaft support 1, and a push die 3 is attached to the cylinder 10. The pressing die 3 is movable along the longitudinal direction of the arm 2 by expanding and contracting the rod 10a of the cylinder 10. The pressing die 3 and the pressing die 4 can be moved by a movement along the longitudinal direction of the arm 2 until they come into contact with each other, and the work a placed on the arm 2 is clamped from the inner and outer surfaces. You can do it. A workpiece a placed on the arm 2 is provided on the end faces of the pressing die 3 and the pressing die 4 facing each other.
A contact surface 6 for angling the work a at a predetermined angle is formed. By sandwiching the work a by the pressing die 3 and the contact die 4, the work a is angled at a predetermined angle by the contact surface 6. Is becoming

A plurality of the work arms 5 are arranged next to each other on the base 7 so as to be rotatable in the horizontal plane by the shaft attachment of the shaft support 1. Here, since the plurality of work arms 5 need to be arranged adjacent to each other in the horizontal plane,
The shaft support parts 1 of the adjacent work arms 5 are in a state of being vertically displaced, and by vertically mounting the shaft support parts 1 which are vertically displaced as shown in FIG. They are arranged so that they are adjacent to each other.

As shown in FIG. 4, the work a is made of a long material having a U-shaped cross section formed of a thin metal plate. Has been given. Here, when the work a is bent at the notch 12, the notch 1 is formed on the stepped portion 13 formed by drawing as shown in FIG.
The edge portions of No. 2 are superposed, and this portion is spot-welded to be fixed in a bent state at a predetermined angle.

Therefore, the single work a conveyed to the frame forming apparatus is provided with the push die 3 and the backing die 4 of the work arm 5 in a state in which the plurality of work arms 5 are arranged at predetermined positions set in advance. By moving and holding the bent portion of the work a to be angled, the work a is simultaneously angled and molded into a predetermined polygonal shape. For example, as shown in FIG. 6, the work a is formed into a pentagon. In the case of forming, the working arm 5 is provided with the pressing die 3 and the pressing die 4 having the contacting surfaces 6 according to the bending angles of the respective bent portions a point, b point, c point, d point and e point.
The work arm 5 is arranged at a position corresponding to the length of each side, and in this state, each bent portion of the work a is bent to form a pentagonal frame material. ,
A frame material having a plurality of bent portions can be simultaneously bent by a plurality of working arms 5, and the bent portions can be spot-welded and angled at a predetermined angle as described above. is there. Then, face plates are attached to the front and back surfaces of the molded frame material to form a panel body.

[0014]

As described above, according to the present invention, a push die movable along the longitudinal direction of the arm is provided on the upper surface of the long arm having the shaft supporting portion at one end, and the other end side of the upper surface of the arm is provided. A working die is provided by providing a pressing die movable along the longitudinal direction of the arm so that the pressing die can be moved close to and away from the pressing die, and the work is placed on the arm at the end face opposite to the pressing die and the pressing die. Since a contact surface for forming a predetermined angle is formed, and at least three or more working arms are arranged next to each other on the base so as to be rotatable in the horizontal plane by the pivotal attachment of the shaft support portion. The work bending position can be simultaneously bent by a plurality of work arms arranged side by side, and one work can be bent simultaneously by a plurality of work arms. To form a frame with a specified shape. It is those which may, be molded frame material from the work of consecutive one thing, in which the molding of the frame can be easily carried out it is possible to shorten the molding time of the frame.
