Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing one or a plurality of work pieces fitted to it from a work body, and more particularly to a device provided with a plurality of pushing rods for pushing out the work pieces.

[0002]

2. Description of the Related Art Conventionally, a plurality of work pieces are often cut out from a work body by a cutting machine such as an electric discharge machine, a laser machine, or a gas cutting device. For example, a tapered work piece is a work piece. After being cut out from the body, it will fit into the work body,
The work piece must be pushed out of the work body and removed. Conventionally, the work piece has been removed by a press machine, but as shown in FIG. 12, the large head member 101 attached to the slide 102 is driven downward while the work body W is reversed and fixed. Then, the head member 1
01 abuts on the work W, and one or a plurality of work pieces W
P is pushed downward and removed from the work body W.

[0003]

However, as shown in FIG. 13, the work body W that has been subjected to pocket processing, etc.
Since the recesses of various sizes and shapes are formed, the large-sized head member 101 cannot enter the recess Wa and the workpiece WP cannot be extruded. Further, as shown in FIG. 14, even in a small work body W, the head member 1
Since 01 interferes with the holder 120 of the work body W and the head member 101 cannot contact the work W, the work piece WP cannot be pushed out.

Therefore, as shown in FIG. 15, a single hydraulic cylinder 1 is provided so that it can be inserted into the pocketed recess Wa and interference with the holder can be avoided.
11 and a small head member 113 attached to the tip of the piston rod 112, there is also a press machine 110, but it is not possible to extrude a plurality of workpieces WP at one time, and the head member 113 is used as a work piece. Peace WP
Since it is necessary to position it at a position where it can be extruded, the work efficiency is significantly reduced. It is an object of the present invention to provide a multi-rod type work piece removing device which can deal with various work bodies and can improve work efficiency.

The plurality of push-out rods 31 are supported by the air force of the common pressurized air so as to project toward the side opposite to the air box 32 and be vertically movable for a predetermined stroke.

That is, since the plurality of pushing rods 31 are supported by the air box 32 so as to be able to move up and down, when the pushing unit 30 is driven downward, first, a part of the head member 31a of the plurality of pushing rods 31 is driven. Comes into contact with a flat surface portion of the work W other than the recessed portion Wa, but when the pushing unit 30 is further driven downward, the head member 31a abutting with the flat surface portion of the work W abuts as shown in FIG. While maintaining the state, the head member 31a located on the opening side of the recess Wa enters the recess Wa, and the workpiece WP
Is extruded. Here, in the above description of the operation, the workpiece WP is extruded after the rotary support 10 is inverted, but before the rotary support 10 is inverted, the extrusion unit 30 extrudes the workpiece WP, and then the workpiece WP is extruded. The rotary drive mechanism 60 may be used to reverse the rotary support 10.

Further, as shown in FIG. 9, the two concave portions Wa
Even when the two work pieces WP are fitted in the work body W having, the two work pieces can be removed at once by the pushing unit 30 having the plurality of pushing rods 31. 10, as shown in FIG. 11, when the holding member H is large, the work body W
Is very small, the work piece WP can be extruded even when the holding member H is made large.

Further, since the reversing drive mechanism 60 can reverse the reversing unit 1 by 180 degrees via the rotary support 10, the work piece WP extruded by the head member 31a of the extruding rod 31 can be easily removed. be able to. That is, according to the multi-rod type work piece removing apparatus A, it is possible to deal with work bodies W of various sizes and work bodies W having various shapes.
The work efficiency can be remarkably improved.

Next, a description will be given of a modified mode in which the multi-rod type work piece removing device A is partially changed. The same parts are designated by the same reference numerals.
In the push-out unit 30, the air box 32 may be increased in size so as to accommodate a large work body. Further, in the fixing portion 20, four or more clamp devices 25 may be provided to securely fix the work body W.
