Design of the Automatic Position Block for the Punched Holes on Angle Steel of Transmission Tower
It is proposed that the design and operation process of the automatic position block for the holes punching used for the angle steel of transmission tower structure. It consists of position block, slide block, screw, nut, motor, and controller. If the anchor points have been set, the hole punching position can be anchored automatically, and setting the anchor points are easy operated. It can equipped in punching press, and improve greatly the current hole punching process.
