Adjustment method of square tube punching machine
Adjust the sliding friction of the hands: Set the hands to zero, put them into the starting detection position, lightly press the release button, and oscillate. At this time, the hands must not exceed zero. Otherwise, you will pay attention to the lubrication of the needle bearings or loosen the hands and adjust the resistance.

Puncture position adjustment: within the measuring range, when placed in the center of the bottom, the head of the puncture head should be placed within 5mm by horizontal flip.

In order to prevent the zero friction ring resistance of the proofreading needle, the aluminum alloy plate and the sample clamp are in the middle of a small equilateral triangle hole, and the pressure in the middle of the plate is then released. The puncture head is fixed and the anti-friction ring is observed. If it does not meet the requirements, adjust the head of the three-ball screw to increase or decrease the yellowing pressure.

Placed at the rear end of the body weight for total torque correction plus a hole shaft, the small shaft screw is always released at the bottom place, the side or top of the bolt under the red top is balanced on the scale plate, released, on the balance Increase the net weight at the other end until the pendulum is parallel to the plane.
