Shear blade is not a professional to operate without adjustment

The first thing to look at is whether your machine will adjust the gap after a tool change, or whether it will be repaired and adjusted. If it is completely chaotic, it will be gradually adjusted step by step. The number of indications is adjusted to 50 filaments. From the beginning, one grid is used to adjust the gap. Use a feeler gauge to adjust the thickness. For various thicknesses of sheet metal, the edge clearances are different. See the diagram for the relationship between the gap size and the thickness. During the gap, rotate the flywheel by hand to make the upper tool rest to the bottom dead point, loosen the screws of the fixed blade on the worktable, determine the clearance value according to the thickness of the shear plate, and use the feeler gauge to measure the full length of the cutting edge. The flywheel moves the upper tool holder up and down several times, gradually tightens the bolts and nuts, and adjusts the clearance of the cutting edge to the required value. Then tightens all the bolts of the fixed blade of the worktable and checks the gap value again until it reaches the requirement. .

After adjusting the other one without adjustment, set it to zero. Then make detailed adjustments. At this time, you must ensure that the three threads can not enter the five wires can not enter it. Remember that its silk is pulled one by one or pulled two. Be serious, or you will bite a knife. In fact, when we do it, we must pay more attention to it, or we must pay attention to it.
