摘要： An assembly includes a die and a punch which cut a hole in a workpiece. The die has a base wall having outer and inner surfaces and a passageway extending therethrough, and a wall extending from the base wall. The inner surface of the base wall has at least one portion which is angled relative to a central axis of the die. The punch includes a body having a bore therethrough, a leading edge on the body which is capable of piercing and cutting a workpiece, and cutting edges on the body for cutting a hole in the workpiece. The leading edge has inclined surfaces between the bore and the piercing points which engage with the portion of the inner surface of the die.
摘要翻译：组件包括模具和切割工件中的孔的冲头。模具具有底壁，其具有外表面和内表面以及从其延伸的通道，以及从底壁延伸的壁。底壁的内表面具有至少一个相对于模具的中心轴线成角度的部分。冲头包括具有穿过其中的孔的主体，能够刺穿和切割工件的主体上的前缘以及用于切割工件中的孔的主体上的切割边缘。前缘在孔与穿刺点之间具有与模具的内表面部分接合的倾斜表面。

摘要： A die is configured for use with a punch capable of piercing and cutting a workpiece. The die includes a base wall having a perimeter, an outer surface and an inner surface, a depending wall extending from the perimeter, a passageway extending through the base wall, and a central axis extending through the passageway. The outer surface of the base wall is perpendicular to the central axis. The inner surface of the base wall has a first portion which is angled relative to the central axis at a first angle which is greater than 90 degrees, and a second portion which is angled relative to the central axis at a second angle which is greater than 90 degrees. The first and second angles are different. The first portion extends from the depending wall to the second portion. The second portion extends from the first portion to the passageway. The second portion engages the punch when the punch is fully inserted into the die.

摘要： A punch assembly includes a punch, a sleeve, a draw stud and a die. The punch has a punch profile which provides a cutting edge that has a uniform “sharpness” along entire perimeter of the punch. The punch assembly provides additional punch-to-die clearance over what was done in the prior art. This reduces excessive punching forces which result from axial deflection of the draw stud and “tipping” of a large diameter punch as the draw stud deflects under a load.
摘要翻译：冲头组件包括冲头，套筒，拉杆和模具。冲头具有冲头轮廓，其提供沿着冲头的整个周边具有均匀“锐度”的切削刃。与现有技术中所做的相比，冲头组件提供了额外的冲头到模具间隙。这样可以减少由于拉杆在负荷下偏转时拉伸螺柱的轴向偏转和大直径冲头的“倾翻”引起的过多的冲压力。

摘要： A punch assembly includes a punch, a sleeve, a draw stud and a die. The sleeve adds rigidity to the draw stud, thereby reducing elastic deflection of the draw stud, reducing bending moment on the draw stud, reducing punching force, and extending the punch, draw stud and die fatigue life. The sleeve also aids in axial alignment of the punch, die and workpiece with a pilot hole drilled through a workpiece.
