    • A method for manufacturing a lead frame and an apparatus therefor are provided to reduce fabrication costs by forming a compressing portion of the lead frame using a low cost press treatment. A lead frame main material(10) is supplied to a portion between a dice(100) and a blanking punch(400). An opening portion is formed on the lead frame main material by removing a portion from the lead frame main material using the blanking punch. The dice and a compressing dice(200) are properly arranged. At this time, a stepped portion is formed between the dice and the compressing dice. The resultant lead frame main material is inserted between the dice, the compressing dice, a pressing dice(300) and the blanking punch. A compressing portion is formed on the lead frame main material by using the pressing dice. At this time, the lead frame main material is blanked out by using the blanking punch.
    • 提供一种用于制造引线框架的方法及其设备,以通过使用低成本的压制处理形成引线框架的压缩部分来降低制造成本。 引线框架主材料(10)被供应到模块(100)和冲切冲头(400)之间的部分。 通过使用冲切冲头从引线框架主材料去除一部分,在引线框架主材料上形成开口部分。 骰子和压缩骰子(200)被适当地排列。 此时,在骰子和压缩骰子之间形成台阶部分。 将得到的引线框架主材料插入在模块,压缩模块,压制模块(300)和冲切冲头之间。 通过使用压骰子在引线框架主材料上形成压缩部分。 此时,使用冲裁冲头将引线框架主材料冲裁掉。

    • PURPOSE: A piercing method and a piercing apparatus are provided to obtain uniform cross section of connector pin, reduce asymmetry of the connector pin, particularly convexity and asymmetry of upper and lower surfaces of cross section of the connector pin, control displacement of the connector pin and improve productivity of piercing process. CONSTITUTION: The piercing method comprises a step of preliminarily shearing a part of thickness of a matrix(41); and a step of completely piercing a preliminarily sheared part(70) in the preliminarily sheared matrix(41). The piercing apparatus comprises a preliminary shearing punch(51) for preliminarily shearing a part of thickness of a matrix(41); a preliminary shearing punch guide block(52) that has a certain clearance with a matrix contact part and is adjacent to the punch; and a preliminary die(53) on which a shearing corresponding part(61) is formed in such a way that the shearing corresponding part that has a certain clearance with the matrix contact part and has depth corresponding to the part of thickness preliminarily sheared in the thickness of the matrix, wherein an elastic means is installed on an upper part of the preliminary shearing punch, and wherein depth of the shearing corresponding part of the preliminary die corresponds to 5 to 40% of thickness of the matrix.
    • 目的:提供穿孔方法和穿刺装置,以获得连接器针的均匀横截面,减小连接器针的不对称性,特别是连接器插脚横截面的上表面和下表面的凸度和不对称性,控制连接器插脚的位移 并提高穿孔过程的生产率。 构成:穿刺方法包括预先剪切矩阵(41)的一部分厚度的步骤。 以及在预先剪切的基质(41)中完全刺穿预先剪切的部分(70)的步骤。 穿刺装置包括用于预先剪切矩阵(41)的一部分厚度的初步剪切冲头(51)。 与基体接触部分具有一定间隙并与冲头相邻的初步剪切冲头引导块(52); 和预备模具(53),剪切对应部分(61)形成为使得与基体接触部分具有一定间隙的剪切对应部分具有对应于厚度部分中的厚度部分的深度预先剪切 基体的厚度,其中弹性装置安装在预备剪切冲头的上部,并且其中初步模具的剪切相应部分的深度对应于基体厚度的5至40%。
