在厚为0.8mm以上的带、条料上冲制零件时,有时模具采用固定卸料板卸料和固定挡料销作定位零件。由于卸料板与凹模之间的距离不能过大,加上固定挡料销在正前方,使送料很不方便。如果采用图示弹性旋转定位装置,能解决这个问题。带料送入凹模后,首件用手动侧挡料销(图中未画出)定位。首件落料后,将带料往前推,由搭边推动挡料销4绕轴5转动,当搭边越过挡料销后,挡料销在弹簧2和顶销3的作用下,弹回原位,此时,将带料轻轻往回拉,
In the thickness of 0.8mm above the strip, strip punching parts, and sometimes the mold using a fixed discharge plate and the fixed block for the positioning of parts for the pin. Due to the distance between the discharge plate and the die can not be too large, plus the fixed block in front of the pin, so feeding is very convenient. If you use the elastic rotation of the positioning device can solve this problem. After the material is fed into the die, the first piece is positioned with a manual side fence pin (not shown). After the first piece of material is blanked, the strip is pushed forward by the edge to promote the material retaining pin 4 to rotate around the shaft 5. When the edge passes over the material retaining pin, the material retaining pin is under the action of the spring 2 and the top pin 3, Back in place, this time, the strip gently pull back,
