图1所示为一夹箍件,设计的弯曲模如图2所示。坯料首先放在两活动凹模2定位槽中,工作时,凸模1将坯料压过两活动凹模2的夹刃口,凸模继续下行并碰着两活动凹模2的底部,这时,两活动凹模2才绕两销轴3的圆心转动与凸模1继续压下,直至最后成形。两活动凹模靠凸模回升时的带动和下面弹簧4的作用而复位。 Figure 1 shows a clip, the design of the bending mode shown in Figure 2. The billet is firstly placed in the positioning grooves of the two movable concave molds 2. When working, the convex mold 1 presses the blank over the clamping edge of the movable concave mold 2, the convex mold continues to descend and touches the bottom of the two movable concave molds 2 , Two activities die 2 is only around the center of the two pin 3 rotation and punch 1 continue to press until the final shape. The two activities concave die driven by the punch when the pick-up and lower spring 4 reset.
