一、前言我国自行设计制造的大型卧式液压机,从投入生产以来,对这台液压机来说,尽可能的减轻体力劳动,充分发挥为军工生产出高精型材:空心型材、空心板材、异型管材、带筋板材等。消除裂纹、硬弯,提高成品率,选择最佳挤压速度,是我们研究的主要任务。挤压生产工艺技术要求设备具有最理想的变速(挤压速度)机构,既能减轻体
First, the foreword Our country designs and manufactures the large-scale horizontal hydraulic press, from put into production, to this hydraulic press, as far as possible reduces the manual labor, give full play to the military industry to produce the high precision profile: the hollow profile, the hollow plate, the special-shaped pipe , With ribs plate. Elimination of cracks, hard corners, improve yield, choose the best extrusion speed, is the main task of our study. Extrusion production technology requires equipment with the best speed (extrusion speed) institutions, both to reduce body
