鱼尾板是我厂的老产品。过去几乎所有工序都是手工操作,后来虽经过多次改进,使前几道工序:切断、加热、冲孔、淬火联成一条作业线,但经淬火后的鱼尾板不能及时检查,生产周期很长,由于车间面积有限,经常造成堵塞,工人的劳动强度很大,劳动条件恶劣。为了改变这种局面,该厂工人在文化大革命前曾多次提出要搞鱼尾板生产联动线,但是当时的走资派和技术“权威”百般阻挠。对老工人根据多年的生产实践提出的鱼尾板淬火建 Fish tail board is my factory’s old products. Almost all processes in the past are hand-operated, but after several improvements later, the first few processes: cutting, heating, punching, quenching into a line, but after quenching the fish plate can not be checked in time, the production cycle Very long, due to the limited size of the workshop, clogging is often caused, the workers are labor-intensive and the working conditions are harsh.
