    • This invention provides a punch blade formed with a burr inwardly projecting from an outer peripheral edge of a blade tip portion, wherein a film made of a coating liquid is formed inside a tip portion of the punch blade, a portion of the coating liquid forms a coating accumulation at the burr, and the film and the coating accumulation can form the inside of the outer peripheral edge and a periphery of the burr into smooth surfaces, so that a punch residue cut by the punch blade and the lower blade slides on the smooth surface of the film and a surface of the coating accumulation covering the burr, and falls downward, thereby providing the punch blade in which the punch residue does not remain in the blade tip portion with a simple structure.

    • A method of shearing a thin metal sheet having a thickness of approximately 0.1 mm or less so as to be separated into a product and scrap by a pair of dies. A chamfer or a round having a size of approximately from 5 to 10 times greater than the thickness of the thin metal sheet is arranged at the lip of a first die which presses one portion of the thin metal sheet which is to be scrap. A chamfer or a round is not substantially arranged at the lip of a second die which presses the other portion of the thin metal sheet which is to be a product. A backing material and the thin metal sheet are overlapped so as to be a laminate. The backing material has a thickness of approximately 2 times or more greater than that of the thin metal sheet and is formed of a flexible material having a very small elongation and is soft enough not to substantially prevent the thin metal sheet from being sheared, such as, for example, paper. The laminate is arranged such that the backing material faces the pressing surface of the first die and that the thin metal sheet faces the pressing surface of the second die. Then, the thin metal sheet and the backing material are sheared concurrently. Thus, the thin metal sheet can be sheared, by methods such as blanking and piercing, while inhibiting burring, without requiring any special type of device or blanking die.
    • 一种剪切厚度为约0.1mm或更小的薄金属片以便通过一对模具分离成产品和废料的方法。 在第一模具的唇缘处设置有比金属片厚度大约5至10倍的倒角或圆形,该第一模具的一部分压制要被废料的薄金属片的一部分。 倒角或圆形基本上不布置在第二模具的唇部处,该第二模具挤压作为产品的金属薄片的另一部分。 背衬材料和薄金属片材重叠成层压体。 背衬材料的厚度大约为薄金属片的2倍或更大,并且由具有非常小伸长率的柔性材料形成,并且足够软而不能基本上防止薄金属片材被剪切,例如 ,例如纸。 层压体被布置成使得背衬材料面向第一模具的按压表面,并且金属薄片面对第二模具的按压表面。 然后,薄金属片和背衬材料同时剪切。 因此,可以通过诸如冲裁和穿孔的方法来剪切薄金属片,同时抑制翻边,而不需要任何特殊类型的装置或冲裁模具。

    • First and second shaving dies are mounted one above the other and are respectively provided with continuous shaving edges disposed adjacent to contoured annular facial surfaces which draw the shaved material away from the work piece as the shavings are removed by the associated shaving edge. An air nozzle mounted in proximity to the first die directs a jet of air across the contoured facial surface of the first die to blow the removed material away from the first die to prevent its interfering with the operation of the second die. The second die is located directly below the first die and is provided with a plurality of angularly spaced troughs lying immediately adjacent to and below annular facial surfaces on the second die for carrying the shavings from the shaving edges of the second die to a sump located below the second die.
