y6液压机是国内各飞机工厂使用的主要液压成形设备之一,由于液压机的传压部件——内胎的寿命低,严重影响了y6液压机的正常使用,致使不能在生产中发挥作用。为解决y6液压机内胎寿命问题,部给一七二厂和北航下达了研制聚氨酯内胎的任务,要求寿命达万次以上。为此,一七二厂组织了科研组,在北航等单位的配合下,研制出了具有性能指标良好的配方、先进的浇注工艺和设备,浇制出了质地优良、使用寿命达万次以上的y3和y6内胎,达到了预期的目的。目前,已通过厂级鉴定,并申请部级鉴定。
The y6 hydraulic press is one of the main hydroforming equipment used by various aircraft factories in our country. Due to the low pressure life of the pressure transmitting part of the hydraulic press, the inner life of the inner tire seriously affects the normal use of the y6 hydraulic press and can not play a role in the production. In order to solve the problem of inner life of y6 hydraulic press, the department assigned to No.172 Plant and Beihua the task of developing polyurethane inner tube, and required lifespan to reach over 10,000 times. To this end, one hundred and seventy-second plant organized a research group, with the cooperation of Beihang and other units, developed a formula with good performance indicators, advanced casting technology and equipment, poured out of the excellent quality, service life of 10,000 times Y3 and y6 inner tube, to achieve the desired purpose. At present, it has passed the factory level appraisal and applied for ministry appraisal.
