(1) design points
(1) block the body oil channel as concisely as possible, to minimize the deep hole,

inclined holes and process Kong;banjo hose fittings
(2) For components with vertical or horizontal installation requirements,

installation requirements for the design Manifold;
(3) compact, small size, light weight;
(4) should work requires frequent adjustment of components (such as relief valves,

speed control valve, etc.) installed on a bit of ease of operation and observation

Home;
(5) blocks to set up a sufficient number of measurement points.metric hydraulic hose fittings
2 dimension taboo
Base surface, the coordinates of the type two dimension the method. Compact complex

manifold block should coordinate type, namely

Choose a corner of the block (usually in the lower left corner of the main view) as

the origin of coordinates, the form of xyz coordinates to mark the center

coordinates of each hole,

Installation surface using on ly the coordinates of France marked the location of the

base screw holes, the rest of the size of base screw holes marked. Sobsp hydraulic fittings

, Both for the CAD, CAM, and also facilitate the hand-drawing, paste component model

pattern (for the selected components, according to product samples, painted

It is the top view and outline of the bottom of eclipse mouth position size

drawings) and the channel position.
3 material selection taboo
Under low pressure manifold block is generally used in ductile iron as well, because

of its workability, especially for deep hole machining. However, cast iron

The thickness of the block should not be too large, with increasing thickness, loose

the tendency of its internal organization, the effect of pressure on oil-prone

Leakage, it is not appropriate f or medium and high pressure situations.
Withstand the high pressure manifold and the general election of 20 steel and 35

steel.
Withstand high pressure manifold block is the best choice of the 35 forged steel.
Mobile machinery and injection molding machines, machine tools and other special

requirements of the occasion, and sometimes also used aluminum alloy to reduce

weight, Manifold,

Then pay attention to the strength design.
Used in the rough may not have trachoma, mezzanine and other defects, as necessary,

to detect.
Cast iron block and large block of steel prior to processing to cope with the aging

treatment or annealing treatment, in order to eliminate the internal stress.
