Drawings
Fig. 1 is a schematic structural view of a split punch according to an embodiment of the present invention.
Detailed Description
Fig. 1 schematically shows a split punch 1 according to an embodiment of the present invention. As shown in fig. 1, the split punch 1 includes a punch 1 and a punch cover 2.
The punch 1 includes a rod body 13, and a first connecting portion 11 and a second connecting portion 12 connected to both ends of the rod body 13. The joint of the rod body 13 and the first connecting part 11 is a reverse round angle. The joint of the rod body 13 and the second connecting part 12 is a reverse round angle. The end face of the first connecting portion 11 and the corner of the side wall are rounded. The end surface of the first connecting part 11 is a flat cambered surface type. The diameter of the first connection portion 11 is larger than the diameter of the rod body 13. The second connecting portion 12 includes a cylindrical section 121 and a truncated cone section 122. The smaller diameter end of the truncated cone section 122 is connected to the rod body 13. The larger diameter end of the truncated cone section 122 is connected to the cylindrical section 121. The corners of the end faces and sidewalls of the cylinder segments 121 are rounded. The end surface of the second connecting portion 12 is a flat surface. The diameter of the second connecting portion 12 is larger than the diameter of the rod body 13. The punch 1 is of an integrated structure.
The punch sleeve 2 is sleeved outside the punch 1. Specifically, a part of the first connecting portion 11 is caught in the punch sleeve 2, and the other part of the first connecting portion 11 protrudes from the punch sleeve 2. The utility model discloses a drift 1 is the disjunctor with drift cover 2 for the difficult fracture in the part of drift cover 2 is outstanding to drift 1. The outer surface of the first connecting portion 11 is in close contact with the inner surface of the punch housing 2 with no gap therebetween. The outer surface of the second coupling portion 12 is in close contact with the inner surface of the punch sleeve 2 with no gap therebetween. Thereby making the punch 1 and the punch sleeve 2 firmly connected. A gap is arranged between the rod body 13 and the punch sleeve 2. The utility model discloses a be equipped with the clearance between drift 1 and the drift cover 2, can release certain stress, improved the life-span of mould. The punch sleeve 2 is of an integrated structure. The punch sleeve 2 comprises a first section 21, a second section 22 and a third section 23, wherein the first section 21 and the third section 23 are hollow cylinders, the diameter of the first section 21 is smaller than that of the third section 23, the second section 22 is hollow circular truncated cone, the first section 21 is connected with one end, with the smaller diameter, of the second section 22, and the third section 23 is connected with one end, with the larger diameter, of the second section 22.
