木箱包角用的铁皮以往都是将打包铁皮剪成10厘米左右的条子,然后用冲头在两头各冲一个钉钉子用的眼儿。这两道工序、三个动作都用手工操作,劳动强度大、产量低、长短也不一样,不能适应生产需要。 后来我们改用冲床剪切和冲眼,工效虽有提高,但因用手工进料,劳动强度仍然较大,而? In the past, the tin used in wooden corners was cut into 10cm strips and then punched with nails on both ends. The two processes and the three operations are all manually operated. The labor intensity, the low output and the length are not the same, and they cannot adapt to the production needs. Later, we switched to shearing and punching with a punch press. Although the work efficiency was improved, due to manual feeding, the labor intensity was still relatively large.
