一、事故情况简介与分析HVAP160油压校正机是西德 EVMVCO 公司为我厂设计制造的前梁自动锻造线上的一台设备,它用于校正和挤压前梁弹簧座到规定尺寸并校准弹簧座平面与两端头的相对歪斜度。在校准过程中,还应使前梁沿轴向延伸约9毫米,达到产品设计要求。该机是保证前梁尺寸及精度要求必不可少的单一关键设备。该设备从1978年投产以来,一直使用正常。1986年2月14日,在前梁生产过程中,当滑块刚刚升至上死点,突然出现滑块从上
First, the accident situation brief introduction and analysis HVAP160 hydraulic correction machine is West Germany EVMVCO company designed for my factory front beam automatic forging line of a device that is used to calibrate and squeeze the front beam spring seat to the required size and calibration The relative skew between the spring seat plane and both ends. In the calibration process, the front beam should also be extended about 9 mm in the axial direction to meet the product design requirements. The aircraft is to ensure the size and accuracy of the front beam is essential to a single key equipment. The device has been in normal use since it was put into operation in 1978. February 14, 1986, before the beam production process, when the slider has just risen to the top dead center, suddenly appeared from the slider
