The feeding length of high-speed roller feeder is adjusted by adjusting the degree of eccentricity. The greater the degree of eccentricity, the longer the length of the feeder. The degree of eccentricity is transferred to the main shaft of the feeder through the pull rod.How do we determine this degree?The rod length measure is: when the punch slider is at the upper dead center, the rod and rocker arm are at 90 degrees.Why make it 90 degrees?Because the pull rod and arm into 90 degrees, the pull rod length is just right, if not 90 degrees, when the feeder is close to the maximum feeding step distance of high-speed feeder, it will cause the pull rod length is too short or too long, easy to cause the rocker arm or drive shaft break phenomenon.
How to make the pull rod of the high speed roller feeder 90 degrees from the rocker arm?When installation, the first host and eccentric disc installed, and then press stop on the slider top dead center, the high-speed roller feeder on the spindle radial and cross regulation into 90 degrees or so, take a tape measure eccentric disc on the cross to the length of the cross on the main shaft, the rod three installed to the measurements for the length of the lock nut.Then install one end of the three-section installed pull rod on the eccentric disc, and the other end on the rocker arm, and then check whether the pull rod and rocker arm are 90 degrees, if not 90 degrees, loosen the nut, and then transfer the middle tube to adjust the length, you can make the pull rod and arm 90 degrees.
If the feeding starting position and feeding ending position, pull rod and rocker arm cannot be in a straight line, stop the punch at a dead point, loosen the pull rod to make the rocker arm 90 degrees from the pull rod, and then lock the nut.
