CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

The adjustment of blade gap of  hydraulic shearing machine  is an important factor to influence the shear quality and prolong the life of the blade. When the gap is adjusted, the lock screw will be released and then turn the handle to the required calibration value to lock the screw again. The ball valve shall be used to measure the evenness of the blade gap between the upper and lower blades. The specific method is a single trip, when the upper and lower racks to the lower dead point, that is, quickly turn the ball valve to close the oil road, so that the upper tool rest stops at the bottom dead point. Then, the micro open and closed ball valve is continued, and the upper tool holder is increased on the whole trip, and the clearance of the blade gap can be measured at this time. 1. Clean the oil stains on the surface of each machine, and notice that the cutting line on the cut-off valve should be in the open position. 2. The lubricating grease is injected into the oil t...
