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п形钉钉布机,产量增加了3倍,质量也相应提高。п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
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 in our factory have carried out reforms on the operation of the cloth-making process and have made the type nail-nailing machine with a 3-fold increase in output and a corresponding improvement in quality. The structure and working principle of staple nailing machine are as follows: Working principle Foot pedals (1) Pull inner tube (9), nose presser (7) and nose (4) Under this condition, the spring (10) is pulled downward. When the bottom of the handpiece (4) contacts the workpiece, the pressure handle (7) drives the nail plate (5) to continue in the handpiece
