钢制敞车车体部分的变形,特别是端墙板和侧门等每次检修都要花费很多工时才能将变形消除。最近,日本国铁高砂工厂研制出一种效率高又安全的调直夹具。一、端墙板调直作业过去端墙板的调直由于不能采用机械方法进行,因而只能采用煤气进行局部加热,按图1那样进行调直。用这种调直方法时,首先在端板上钻6个孔,挡板用螺栓固定,在另一端的两个侧柱上插入两个
Steel gondola body part of the deformation, especially the end wall panels and side doors and other maintenance each have to spend a lot of man-hours in order to deformation will be eliminated. Recently, Japan’s iron and steel high sand factory developed a high efficiency and safety straightening fixture. First, the end wall straightening operations In the past due to the straightening of the end wall panels can not be used mechanical methods, which can only be used for local heating gas, as shown in Figure 1 straightening. With this straightening method, first six holes are drilled in the end plate, the bezel is bolted, two are inserted on the two side columns at the other end
