    • PURPOSE: A press die for processing a pipe punch, which maintains the precision of the inside diameter, is provided to control damage to a die by forming the cut region of a die and a punch in an obtuse angle. CONSTITUTION: A press die for processing a pipe punch comprises a die plate(2), a die(3), a slide punch plate(4), a punch(5), a cover plate(7), a pad(8) and a punch push plate(9). The die plate is installed on the top of a lower holder(1). A punch hole(3a) is installed on the top of the die plate. The slide punch plate is carried with a lower bolt(12) to the top and bottom. The cover plate is installed in the lower part of an upper holder(6). A pad is elastically supported with a top elastic member(13) and is carried with a top bolt(12) to the top and bottom. The punch push plate presses the slide punch plate. A pipe(10) is arranged between the die and the pad. The punch is arranged in the hollow section of the pipe.
    • 目的:提供一种用于加工保持内径精度的管冲头的压模,以通过以钝角形成模具和冲头的切割区域来控制对模具的损坏。 构造:用于加工管冲头的压模包括模板(2),模具(3),滑动冲压板(4),冲头(5),盖板(7),垫(8) 和冲压推板(9)。 模板安装在下支架(1)的顶部。 冲模孔(3a)安装在模板的顶部。 滑动冲压板带有下螺栓(12)到顶部和底部。 盖板安装在上支架(6)的下部。 衬垫由顶部弹性构件(13)弹性支撑,并且具有顶部螺栓(12)到顶部和底部。 冲压板压入滑块冲压板。 管(10)布置在管芯和衬垫之间。 冲头布置在管子的中空部分。
