摘要:
为提高冲压模具成形速度,研究了用于超高速冲压(UHSS)平台成形母端子PIN和BOX部位冲压模具的滑动夹持成形工位。发现在模具的成形期间,成形滑块表面在半径接触点开始表现出磨损,然后向下产生较长的磨损,分析了滑动表面的几何形状及造成磨损的主要因素,成形滑块在成形期间磨损的主要形式是粘着磨损和分层磨损,夹持块的几何形状和滑动表面的角度是造成磨损的重要原因。对滑动夹持成形工位进行了重新设计,对线性驱动和从动轮廓进行了改进,从开始到结束都采用面滑动,同时原始的滑动面的角度设计变小,减轻了磨损和旋转问题,增加了工位的可调节。
In order to improve the forming speed of stamping die, the sliding clamping forming station of the stamping die used in the ultra-high-speed stamping (UHSS) platform to form PIN and BOX female terminals were studied. It was found that the surface of forming slider began to show wear at the radius contact points during the forming process and produced long wear downward. Then, the geometry shape of sliding surface and the main factors causing wear were analyzed, and the adhesive wear and the layered wear were the main forms during the forming process of forming slider. However, the geometry shape of clamping block and the angle of sliding surface were the important causes of wear. Furthermore, the sliding clamping forming station was redesigned, and the linear drive and the driven contour were improved. Thus, the face sliding from the beginning to the end was adopted, at the same time, the original angle design of the sliding surface became smaller to reduce the wear and rotation problems and increase the adjustable position.
