钣金工折边是一项非常繁重的体力劳动。上海无线电二厂过去用的一台折边机,已有数十年历史,折一次边至少需要两个人;遇到要折一点五至二毫米厚的铁板,就需四、五个人。许多老工人因为长期折边而患了腰劳损病。在毛主席的革命路线指引下,全组同志发扬“独立自主、自力更生”的精神,仅用了不到半年的时间就试制成了两台1000毫米液压折边机,提高了生产效率,减轻了劳动强度。这种折边机以液压和电器作控制,自动化程度较高。它的最大加工长度为1000
Sheet metal folding is a very heavy manual labor. Shanghai Radio Factory in the past with a folding machine, has decades of history, at least one side of the need for two people; to encounter a little bit five to two millimeters thick iron plate, you need four or five people. Many old workers suffer from waist strain because of long-term hemming. Guided by Chairman Mao’s revolutionary line, all the comrades carried forward the spirit of “independence, self-reliance and self-reliance.” In less than half a year, two 1000-mm hydraulic edge-folding machines were trial-produced to improve production efficiency and ease Labor intensity. This folding machine hydraulic and electrical control, high degree of automation. Its maximum processing length is 1000
