我厂生产的内外销钢管折椅,其椅座和椅靠背都必须包以布或人造革。过去都是采用鎯头钉鞋钉来固定,操作不便,效率低,而且劳动强度大。随着产量的激增,包布工序与其他工序出现不平衡。因此,我厂广大职工在无产阶级文化大革命的推动下,对布工工序的操作进行了改革,制成了脚踏Π形钉钉布机,产量增加了3倍,质量也相应提高。Π形钉钉布机的结构及工作原理如下: 工作原理脚踩脚踏板(1)通过拉杆(13)带动内套钢管(9)、机头压把(7)和机头(4)向下,此时弹簧(10)被向下拉伸。当机头(4)底部接触工件时,压把(7)带动钉钉板(5)在机头内继续往下,把Π形钉压入工件内(此时弹簧(6)被
I plant the production of steel pipe folding chairs, the seat and backrest must be covered with cloth or artificial leather. In the past are used to fix the head nails spikes, inconvenient, inefficient, and labor-intensive. With the surge in output, there is an imbalance between the cloth covering process and other processes. Therefore, under the impetus of the Great Proletarian Cultural Revolution, the vast majority of workers and staff of our factory have carried out reforms on the operation of the cloth-making process and made the Π-shaped staple-nailing machine with a tripling in output and a corresponding improvement in quality. The structure and working principle of Π-staple nailing machine are as follows: Working principle Foot pedals (1) Driving inner sleeve steel pipe (9), nose presser (7) and handpiece (4) Under this condition, the spring (10) is pulled downward. When the bottom of the nose (4) touches the work piece, the pressure plate (7) drives the nail plate (5) to continue down in the handpiece to push the Π nail into the work piece (at this moment, the spring
