前言我厂所生产的管材有百分之八十以上是三千五百吨水压机生产的。该设备每月平均为六百三十吨水压机提供二次挤压管坯料四十吨左右,占设备总产量百分之三十。挤压车间革新队共同努力搞了一套穿孔针限程装置,用于生产后,提高了二次挤压管坯料的生产效率,降低了能源消耗,节省了人力和辅助工具。一、改进前二次挤压管坯料的生产方式 Preface I produced more than eighty percent of the pipe is the production of 3,500 tons of hydraulic press. The equipment provides an average of about 40 tons of secondary extruded pipe billets per month for 630 tons of hydraulic presses, accounting for 30% of the total equipment output. Extrusion workshop team worked together to create a set of perforation needle limit device for production, improved production of secondary extrusion billet efficiency, reducing energy consumption, saving manpower and auxiliary tools. First, to improve the production of the first two extruded tube material
