切割下料时,由于下料件的几何形状以及套料件的间距受切割热的影响,工件会发生不同程度的变形。在生产一批环形卷制件过程中,展开件在火焰切割下料时产生旁弯现象,导致卷圆件错边严重,无法使用。探索采用500 t四柱油压机配合自制模具进行机械矫正,矫正后的工件可以满足后续加工工序的要求,避免了材料浪费。介绍自制模具的结构组成和矫直方法。
Cutting cutting, due to the geometry of the blanking parts and the spacing of blanking parts affected by the cutting heat, the workpiece will have different degrees of deformation. During the production of a number of toroidal coils, the unfolding of the flaps causes flaw during flames cutting, resulting in serious miswinding of the coils and can not be used. Explore 500 t four-column hydraulic press with a homemade mold for mechanical correction, after the correction of the workpiece to meet the requirements of subsequent processing steps to avoid material waste. Describes the structure of self-made mold composition and straightening methods.
