|Vertical scraping rolling and rolling composite processing
technology, a reciprocating scraping rolling function can be
completed. The machining precision can reach IT8 level, the surface
roughness can reach Ra005-0.2 M. Mainly used for hydraulic cylinder
hole machining, compared with traditional honing machine the
equipment with low noise, no pollution, and can greatly save labor
cost, high processing efficiency. Than the old boring and rolling
or boring and honing can save processing time of 80-90%.|
Processing capacity: ability to the cylinder hole scraping and
rolling completed a one-time processing. The production efficiency
is greatly improved, 80 times more than the traditional machining
method. Achieve the cylinder wall mirror effect (Ra = 0.03um~0.2um)
Vertical scraping rolling machine which is specialized in
manufacturing hydraulic cylinder processing equipment, this is
another breakthrough in reform, a technical problem of deep hole
technology. It is the deep 2-3 process to complete the work,
one-time finish. The pusher and a complete coarse scraping,
completing this procedure at the same time after rolling scraping
by retracting the opportunity. The rolling process, the workpiece
roughness of Ra0.2. Can replace the ordinary honing of deep hole
and. Deep hole processing rolling technology is a non cutting
processing, the internal surface of workpiece surface roughness
reaches requirements of several major advantages of rolling
deformation by attributes:
1、improve the surface roughness, roughness can reach Ra0.2 M.
2、The 2 amendment, roundness, elliptic degree0.02mm. Coaxial
3、improve the surface hardness, so that the pressure eliminating
deformation, hardness HV ≥;
4、after processing any residual stress layer, and increase the
fatigue strength increased by 30%
The burnishing tool on the workpiece surface rolling finishing and
rotation, the uneven pressure, at the same time, the excess
material into the gap. It can produce plastic deformation. The near
surface material layer flow, to achieve smooth effect, the
processing speed is determined by the material and the needed
surface specifications. Features and advantages:
1) surface quality to Rz< 1 M.
2) dimensional stability of high grade It8, tolerance.
3) assembly processing safety rapid and low cost.
4) using only one procedure.
5) finish surface harder and more wearable.
6) tool is simple, no extra cost.
7) to very fast and safe production.
8) very high load bearing ratio (up to 90%).
9) compared with grinding, honing or lapping, very economic.
10) surface hardening is between 5% - 10%.
11) short processing time. Every minute line speed can be up to one
12）long service life. Can improve the life of sliding parts,
hydraulic, pneumatic cylinder type O ring and gasket sealing
material with resin and metal. Sealing material to friction and
cylinder, so the sealing material should have good compliance and
metal, as well as in the seal without due to friction wear. Convex
portions are formed by section curve grinding and shot peening
after processing, the protruding part will be significant wear
sealing material. The rolling process is the protruding part of
RCC, thus forming a smooth plane, and the contact fluid sealing
materials, significantly reduced the rod sliding and wear, it is
widely used in automobile brake cylinder, oil cylinder, valve body
and a buffer to manufacture field.
