我厂章阿大同志根据一般冲头的原理,改进成功一种多弧形的快速冲头(材料用у8,у10,XВГ)。这种冲头有下面几个特点: 1.中部的弧形成鯽魚背形状,因而使冲头在高温和較强的冲击力下不容易发生弯曲。 2.在接近头部的地方有小退拔,两端比較平,这样可以防止冲头因冲孔受热鐓粗而拔不出来。 3.冲头外部流綫和材料的纖維組織成平行,在冲孔的时候可以防止“吃
I am a factory comrade according to the general principle of a punch to improve the success of a multi-arc fast punch (material у8, у10, XВГ). The punch has the following characteristics: 1. The middle of the arc into a crucian carp shape, so that the punch in the high temperature and strong impact is not prone to bending. 2. In the vicinity of the head there is a small pull-off, both ends of the relatively flat, so you can prevent punch due to punching heat upset and can not pull out. 3. Punching the external flow lines and materials in parallel to the fiber organization, when punching can prevent "eat
