Hydraulic System Adjustment And Accumulator Pressure Checking

Sometimes if Guillotine shearing machine model QC11K-30*2500mm or QC11K-30*3200mm hydraulic systems occurs problems ,how to adjustment and how to Accumulator pressure checking? Don’t worry.

Turn on the power, select the switch to set the “jog position” and jog the “Jog on” and “Jog on” buttons, and the solenoid action should match the solenoid action table. The system uses a direct-current wet electromagnet. It can be used with a small iron such as a short saw blade to rest on the examined magnet to see if there is a suction force to judge whether it is energized or not, but when the knife holder presses the lower (or upper) limit switch It is normal for the electromagnet to have no action when the “point up” (or down) button is pressed.

Accumulator gas pressure check The nitrogen pressure of the accumulator needs to be checked regularly (about 30 days inspection), using the accumulator's nitrogen accumulator tool (the tool is placed in the accessory box), the tool's Use the instructions for use of the inflator. If the nitrogen pressure is less than 7MPa, it should be added.

Accumulator Charge When the machine is in use (or after the machine is repaired), if the accumulator pressure is insufficient (or need to be recharged), the oil should be filled in a timely manner. The specific procedure is: The rack runs to the top dead point. Start the oil pump, place the changeover switch in the cutting position, press the “filling button” button on the control panel, and release the button when the pressure gauge shows 9MPa. 

Accumulator charging In the case of machine maintenance, commissioning or use, if you need to inflate the accumulator, follow the procedure below. Two 16L accumulators are used in the system setup. When inflating, after installing the inflation tool on the nitrogen bottle and accumulator, open the nitrogen bottle switch and observe the pressure gauge connected to the accumulator inflation valve. When the pressure gauge shows 6.5MPa, release the button and complete the inflation. Inflatable tool, tighten the accumulator gas filling valve nut. 

If the nitrogen pressure in the nitrogen bottle is low, the above process can be repeated until the use pressure is reached.

Fiber Laser Cutting Machine

Nowadays laser cutting machine is more and more widely used, as it is with high speed, high precision and automation. It can save manpower and improve production efficiency.  The laser is shot from laser generator, through optical system, focus to high power and density laser beam. The beam shoots on surface of workpiece and makes it reach melting point or boiling point, at the same time, the high pressure gas which is on the same axis with laser beam blow the melting or pneumatolytic metal away. That is the basic reason of laser cutting. According to the laser generator, there are two types – CO2 type & fiber type. The frequency of the CO2 laser requires higher wattage of lasers to penetrate through metals. CO2 laser systems are best suited to cutting wood, acrylic, plastic, and fabric.  Fiber laser cutting machine  is much more energy saving. In the situation that reaches same performance, whole fiber cutting can save around 70% energy than CO2 type. The wattage can range from 50

How to Adjust the Clearance of Upper and Lower Blades of Hydraulic Guillotine

To many customers, they can easy to get how to adjust the clearance of upper and lower blades of small model  hydraulic guillotine shearing machines . How every, it's do hard for them to adjustment big models like QC11Y-40*2500 mm or QC11Y-40*3200mm. It is an important factor that affects the cutting quality and prolongs the service life of the blade. The correct adjustment of the blade thickness depends on the shear plate thickness. The machine tool converts the blade gap value to the plate material value directly on the gap dial. The clearance between the upper and lower blades of the shear should be the same throughout the entire length. This shear shall be equipped with a supplementary tool holder on the worktable to be used as a micro adjustment of the uniformity of the gap between the upper and lower blades. The minimum clearance before adjustment is 0.05 mm at the factory. The user should not change easily during normal use. After the blade is used for a certain period of
