The low-speed crawling caused by the uneven friction of the guiding elements in the hydraulic cylinder of the cutting machine is recommended to use metal as the guiding support, and the cutting machine such as QT500-7, ZQAL9-4 Etc. If a non-metallic support ring is used, it is recommended to use a non-metallic support ring with good dimensional stability in the oil. In particular, the coefficient of thermal expansion should be small. In addition, the thickness tolerance and thickness uniformity must be strictly controlled for the thickness of the support ring.
Two brackets for equipment. Use a hexagonal wire cutter to open the cover in the middle of the machine, anti-wear hydraulic oil. After the machine is connected, (three fire lines, one ground wire) after connecting the line, turn on the machine power switch, turn on the oil pump work switch, immediately turn off the power switch; the staff face the motor fan blade, see the motor fan blade clockwise or reverse When the hour hand turns, it must be turned clockwise. If the motor fan blade rotates counterclockwise, in the case of power failure, the position of a live wire can be arbitrarily adjusted.
At this point, look at the cutting depth must be otherwise it will damage the die. Press the button on the top of the machine with both hands, and drag it out after cutting.
Cut the board to see if the material is cut. If it is not cut, fine-tune the cutting depth, adjust a scale and try to see the effect; if it is not cut, then adjust a scale and try again; there is still one point that has not been cut, then adjust the half-scale and try again. Only after you have just cut it, you can adjust half a scale. Remember to only fine-tune the cutting depth.
The debugging procedure of the precision four-column cutting machine is ready for the machine placement position. The three-phase power supply anti-wear hydraulic oil (please buy brands such as Great Wall, Shell, etc.) before the machine is placed, the spare rubber pad is placed at the machine foot, and the machine pedal is fixed. wire.
The influence of the precision of parts processing, in the manufacturing process of the hydraulic cylinder of hydraulic cutting machine, the machining precision of the inner wall of the cylinder and the surface of the piston rod should be strictly controlled, especially Geometric accuracy, especially straightness is the key. In the domestic processing technology, the processing of the piston rod surface is basically after-car grinding, which ensures that the straightness problem is not big, but for the processing of the inner wall of the cylinder, there are many processing methods. Cutting - rolling, boring - honing, direct honing, etc., but because the basic level of domestic materials is different from foreign countries, the straightness of the tube blanks, uneven wall thickness, uneven hardness and other factors often directly affect the processing of the cylinder wall After the straightness, it is recommended to use the boring-rolling, boring-honing process, such as direct honing, you must first increase the straightness of the pipe blank.
