What are the skills of forging processing? Here is a brief introduction of the forging manufacturer.
First, when installing the hydraulic system, promise to use sealing filler or sealant, but should prevent access to the system.
Second, the parts and components to be installed should have an inspection certificate before installation.
Third, the unannotated shape of the public service should be consistent with GB1184-80, the unannotated length scale error of ± 0.5 mm.
Fourth, for the tightening torque regular tightening forgings, you need to choose the torque wrench, according to the regular tightening torque tightening.
V. Strictly check and remove the sharp corners, burrs and foreign objects left in the forging processing before assembly. Make sure the seal will not be scratched during installation.
Six, forgings before installation, it is necessary to organize and clean the parts, there must be no burrs, flying edge, oxide, rust, debris, oil, coloring agent and dust.
Seven, bearing outer ring after installation, should be in the positioning end and bearing cover end face uniform contact, there should be no scratches, scrapes and other defects that damage the appearance of forgings.
Eight, the forging with symmetry in the rough castings fundamental scale configuration. When installing rolling bearings, agree to use oil heating and hot installation, the oil temperature shall not exceed 100 ℃.
Nine, gear (worm wheel) benchmark end face should be affixed to the shaft shoulder (or positioning sleeve end face), with 0.05mm stopper to view not into, and to ensure the straightness between the gear benchmark end face and the axis.
Ten, the surface of the forging does not allow cold compartment, cracks, shrinkage, penetration and serious damage defects. Forgings should be clean, no burrs or flying edge. Non-machining mark on the riser should be flush with the surface of the casting.
Eleven, bearing outer ring and open bearing seat, bearing cover of the semicircular hole is strictly prohibited to jam; bearing outer ring, open bearing seat of the semicircular hole and bearing cover should be in good contact. When observed with colored paint, bearing seat and bearing cover should be symmetrical to the line 120 ° and 90 ° ratio of uniform contact. When observed with a stopper in the above range, 0.03 mm stopper shall not be inserted into the outer ring width of 1/3.
Forgings are suitable for processing various metal parts, non-standard equipment design and manufacturing, mold design and manufacturing, structural welding engineering, wind tunnel combustion chamber design and manufacturing, titanium alloy, high temperature alloy, non-metal processing.
