As shown in the figures, the present invention includes a mold 4 having an upper surface for placing a work piece 1, the mold 4 being a cylindrical hollow cylinder, the hollow cylinder providing an inner surface. The deburring punch 3 corresponds to the hollow cylinder of the die 4, the punch 3 has a punch 8 for punching and cutting off the machined workpiece 1 and a first punch 6 for pressing the remaining part of the workpiece protruding in the groove 2 of the burr 10 to form a boss-shaped burr 10. And a collecting chamber 5 installed on an inner surface of the deburring die 4, the collecting chamber 5 including an upper blocking rib 15. The punch 3, die 4 and collection chamber 5 are configured to capture the slug 7 by scraping off the blocking ribs 15 as the punch 8 is lowered into the collection chamber 5 and raised by the blocking ribs 15.

The mold 4 has a convex portion 11, wherein the diameter of the inner surface of the convex portion 11 is smaller than the diameter of the inner surface of the portion below the convex portion 11; the mold 4 also has a burr 10 groove 2 above the protrusion 11, the inner surface of the burr 10 groove 2 having a diameter larger than that of the protrusion 11.

The inner surface of the groove 2 portion of the burr 10 is tapered, wherein the opening diameter of the top portion in contact with the work 1 is larger than the diameter of the inner surface of the lower portion.

The collection chamber 5 has a cylindrical symmetrical shape comprising an upper horizontal portion, a lower horizontal portion and a vertical portion having a substantially circular shape to be coupled to the inner surface of the mould 4; the upper horizontal portion is configured to have a plurality of blocking ribs 15 radially disposed to point toward the cylindrical axis, and the lower horizontal portion is configured to have a plurality of bottom plates 16 radially disposed to point toward the cylindrical axis, each section of the horizontal portion extending from the vertical portion. The middle of each base plate 16 is provided with a bottom seam 17, and the bottom seams 17 provide superposable gaps when the base plates 16 surround a cylindrical cavity to prevent wrinkles from being generated. The three-dimensional cylindrical structure of the collecting chamber 5 is formed by folding a planar mould along a fold line 18. The length of the bottom plate 16 is longer than the blocking edge 15 to achieve the sealing effect of the bottom.

The length of the protrusion 11, the length of the first punch 6, the diameter of the burr 10 of the die 4 and the length of the horizontal part of the collecting cavity 5 are configured to effectively trap the slug 7 in the gap enclosed by at least a part of the punch 3, the slug 7 being within the space enclosed by the punch 8, the blocking ridge 15, the boss and the first punch 6 when the punch 3 is lowered into the first hole 12.
