Abstract

PURPOSE:To obtain quickly and accurately a high quality O-ring without separating unsuccessfully, by clamping rubber burr sections between cutting dies comprising top and bottom forces, pressing and cutting only item sections by movable pressing bodies provided to one of the cutting dies so that the item sections are pushed into grooves in the other cutting die. CONSTITUTION:A plate body 6 of rubber or rubber-like resilient material is placed on the bottom force 8 of the cutting dies, and the item sections 3 of the plate body 6 are approximately coincided with respective recesses 10. Then the top force parent body 7 is put on the plate body 6, and the center of each annular groove 10 is approximately coincided with the center of each annular recess 13. The rubber burr sections 5 and the cut-off sections 4 of the plate body 6 are clampled by the top force parent body 7 and the bottom force 8. When the press plate 12 is pushed down, annular pushing rings 10 push only the item sections 3 to cut off them from the rubber burr sections, and push them into the grooves 13.

Molded into a plate shape, this burr part is held between a cutting die consisting of an upper die and a lower die, and only the product part is pushed out with a movable pusher provided on one side of the cutting die, and placed in the groove of the other side of the cutting die. This invention relates to an O-ring deburr removal device characterized by a push-in mechanism, and its purpose is to quickly and accurately mechanically remove O-ring deburrs made of rubber or rubber-like elastic material. It is to be removed.

is the lower part of the cutting die. (9) is an annular groove in the upper mold, and (10) is a push ring movably pushed into this groove. A pin (11) attached to this push ring passes through the upper die base. The upper end of this pin (11) is fixed to the push plate (12). A spring (B) is interposed between the push plate (12) and the upper die base (7). The lower mold (8) has an annular groove (1
3). The push ring (lO) is designed to fit loosely into the groove (13). The push ring (10) forms a movable push body.

。Place the plate-shaped body (6) on the lower mold (8) of the cutting die, and place each product part (3) in the plate-shaped body (6) into each recess (13).
Make it match. Next, the upper mold base (7) is attached to the plate-shaped body (6).
- Place it on the center of the annular groove (1o) and the product part (
3) Align the centers of the two. The cut-off portion (4) of the rubber burr portion (5) of the plate-shaped body (6) is held between the upper mold base (Ma) and the lower mold (8). next,
When the push plate (12) is pushed downward, - the push ring (1o) pushes only the product part (3), separates it from the rubber burr part, and places this product part (3) into the groove (13). Push it in.
