The punch presses that are common in everybody's day will cause a safety block due to various conditions, which can maintain the function when overloaded. The second is the separation key, which works and separates the function between the water pump flywheel and the crankshaft. The third type is the brake band, which plays a role of adjustment when the crankshaft reaches the upper starting point. The new one is also equipped with these two vulnerable parts when it is in the original factory. What is the way to avoid frequent damage to the punch safety block at this moment?

The punch application fuse block is a kind of anti-load protection device. When the punching tonnage exceeds the nominal force to reach a certain value, the fuse block installed in the slider will be crushed and destroyed first, thereby protecting other components from damage. The safety block for installing the sliding block has a ball seat, a ball screw, a ball cover and other parts on the upper side. The movement gap is not large. When the bumper is crushed or destroyed or deformed downwards, the thickness of the base decreases, and the gap between the ball head and the bowl and the ball cover will expand. When the slider changes between the left and right dead points, there will be abnormal noises. In this case, you must park immediately Carry out inspections and replace damaged or deformed safety blocks to avoid long-term damage to the ball cover or bowl.

How to change the insurance block for the punch? There is a safety block removal hole on the front of the punch needle, generally under the nameplate. The actual operation steps are: first squeeze the slider point to the upper fixed point or the lower dead point. If there is a balance cylinder or balance block, the gas or balance force inside must be removed. If the pressure is not relieved, the slider will always be run up. Open the window in front of the slider, remove the damaged safety block, check whether the ball head seat moves and run down, if it runs down, put a jack on the template or mold to lift the burr seat from the mold handle hole of the slider, and then put the new Put the fuse block into and install other parts. If the slider has an overload switch, you need to check whether the switch is calibrated. If it is not calibrated, it will report an "overload" fault and cause it to fail to boot.
