The material preparation process of the hydraulic cylinder:
1. The organizer of the hydraulic cylinder assembly must be carried out in accordance with the assembly drawings and operating technical regulations, in accordance with the prescribed sequence and steps, and strictly abide by the process discipline.
2. According to the production plan, the number of hydraulic cylinders shall be collected according to the drawing and list, and the self-made parts, hydraulic cylinder seals and standard parts required for assembly shall be collected and inspected at one time using a turnover truck. Make a mark
a: The self-made processed parts should be inspected for their appearance quality. If there are serious cracks or scratches, and pinhole defects on the electroplated surface, they should be submitted for inspection and re-examination, and minor defects should be repaired. The self-made machining parts should be carefully cleaned, and the screw holes should be tapped back. The surface rust spots and sharp burrs should be removed. The hole interface should be rounded and sanded. The thin edges of the thread advance and retreat tools should be repaired, and generally should be repaired. /4 turns or thread trimming thickness> 0, 5mm.
b: Check the hydraulic cylinder seals. Check the specifications and check the shelf life. The hydraulic cylinder seals that exceed the shelf life cannot be installed, and the hydraulic cylinder seals that are defective in appearance cannot be installed.
c: For the bolts and nuts used, pay attention to whether the strength level meets the requirements of the drawings.
3. Check the repaired hydraulic cylinder parts and carefully clean them. Use gasoline or kerosene as the cleaning agent. After completion, blow dry and stack the hydraulic cylinder parts neatly, cover with moistened burr-free cloth to prevent new dust and particles from sticking. The hydraulic cylinder parts after cleaning should be assembled as soon as possible to avoid new corrosion.
