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 tank to add l-hl46 machine oil (oil must be cleaned). If abnormal noise or fuel tank overheating is found, stop check immediately.
The maximum temperature of the tank is not more than 60 degrees.
3. Open the machine for a number of cycles, and then try to cut different thickness plates (from thin to thick) after ensuring all normal conditions.
In the shear process, open the pressure gauge switch to observe the oil pressure value, if there is abnormal adjustable overflow valve to meet the requirements.
