我厂过去生产汽车散热器片是用150吨冲床冲,工效低,质量差,操作不方便,不能适应汽车工业的发展。我厂广大职工遵照毛主席关于“自力更生”的伟大教导,于1971年2月试制成功一台滚片机(图1)。经过一年来生产实践证明,滚片工艺比冲片工艺有很多优点。现将滚片机简介如下:一、结构原理冲片时冲头是往复运动,冲压成形。滚片时滚轮是旋转运动,滚压成形。 I plant in the past the production car radiator film is 150 tons punch Chong, low efficiency, poor quality, inconvenient operation, can not adapt to the development of the automotive industry. In accordance with Chairman Mao’s great teaching on “Self-reliance”, the vast majority of our factory workers tried out a successful film rolling machine in February 1971 (Figure 1). After a year of production practice has proved that the rolling process than the punching process has many advantages. Roll machine is now briefed as follows: First, the principle of the structure Punch when the punch is reciprocating motion, stamping. Roller is rolling wheel rolling motion, roll forming.
