In the manufacturing process of mechanical parts, tool or grinding wheel legacy, chip separation of plastic intersection and machine vibration factors, make the parts friend surface, always leave subtle composed of tiny spacing and peak valley uneven, the rough rough surface can be seen with the naked eye, fine plus: after the surface with a magnifying glass or microscope can still be observed, the parts with tiny peak surface valley height and spacing condition is called surface roughness also called microscopic roughness.
The cutter pressure machine is uneven resolved
Hydraulic cutting machine with a long time many users will find the ends of the pressure plate uneven, do not know how to solve!
So why can cause cutting = both sides of the material machine pressure is not uniform? The uniform pressure is usually understood as the upper, and the lower table is best without any gap (theoretically). Because the accuracy and cutting effect of the machine are determined by the gap size of the upper and lower workbench. Generally do good manufacturers this gap value will be controlled below 0.05mm.
First of all, the planness of the upper workbench and the lower workbench itself should ensure that, the general machine tool will ensure below 0.05mm, and the four columns or the guide rail connecting the upper and lower workbench should also ensure its processing accuracy, and the final assembly should be repeated for many times to meet the requirements. Before delivery, the parallelism of the upper and lower workstations should not exceed 0.1mm.
There are many manufacturers of machines in the use of a period of time will appear uneven pressure, generally for the following reasons:
1, and for long-term overpressure use.
2. The large workbench is used for a long time and is used in the center position.
3. Use the knife mold in the front and back or in the left and right sides for a long time.
4, enough to buy a small factory of low-quality, low-price machines.
The above is roughly the cause of the uneven pressure.
How to solve: the general pressure is not uniform before and after the depth is different, the left and right depth is not the same and the whole large area depth is not the same as several kinds. Before and after or left and right depth can be solved by correction, the whole large area needs to rework the plane (more troublesome need to return to the factory).
If the service life of the hydraulic cutting machine equipment is long, the daily maintenance work is indispensable! Good maintenance work, can maintain the good performance of the cutting machine, but also can maintain the life of the parts. Notes for daily maintenance of oil pressure cutting machine are as follows:
1. Basic maintenance:
1, the oil pressure cutting machine table should be often wiped clean, can not be stained with lubricating oil, so as not to cut objects touched, affect the appearance of the finished product.
2, cut the board can not leave debris, or stained with lubricating oil, it is best to clean every day, to keep clean.
3, fill in the lubricating oil should pay attention to not touch other parts, if it must be wiped clean.
4. After the cutting machine is used, be sure to clean up the surrounding area to keep the machine clean.
2. Fine maintenance:
1. When using the oil pressure cutting machine, pay attention to whether the lubricating oil in the oil can is still displayed. If not, there is no lubricating oil, please fill in the lubricating oil again.
2. When sending the lubricating oil into the four sliding shaft, just shake the handle back and forth.
3, hydraulic oil is recommended to use 68 # or 46 # hydraulic oil, hydraulic oil is generally replaced once a year.
4, the oil pressure cutting machine for a long time after the shutdown of the start lubrication four sliding shaft.
