Abstract
The utility model relates to hydraulic power unit valve block technical field, especially a kind of power unit valve block assembly.Comprise valve block and frock, valve block casting is in frock, and described valve block is square, and described frock is suitable square mutually with valve block, and described valve block is made up of T6061 section bar aluminium.Described frock four limit end face is provided with the fastener hole be made up of counterbore and through hole two sector hole, and described frock four flank side surface is provided with plug hole.Valve block of material of the present utility model adopts T6061 section bar aluminium, adopts T6061 section bar aluminium can reduce the gas mesh of valve block, reduces the scrappage of product, and provide processing tool suitable mutually, improve the stability of power unit, make product appearance more attractive in appearance.
Description
Technical field
The utility model relates to hydraulic power unit valve block technical field, especially a kind of power unit valve block assembly.
Background technique
Hydraulic power unit valve block of material generally be cast aluminum, watered out the blank of valve block by mould, then blank processed, but aluminum alloy melting and cast time, can a large amount of hydrogen be absorbed, then constantly separate out because of the decline of solubility during cooling.Some data introductions, the more hydrogen dissolved in aluminum alloy, its solubility increases with the rising of aluminium alloy temperature, and reduce with the decline of temperature, when becoming solid-state by liquid state, the solubility of hydrogen in aluminum alloy declines 19 times.Therefore aluminum alloy melt is in the process of setting of cooling, and in a certain moment of hydrogen, the content of hydrogen has exceeded its solubility and namely separated out with the form of bubble.The bubble hydrogen formed because oversaturated hydrogen is separated out, having little time floats discharges, in process of setting, just form pore that is tiny, that disperse, i.e. our said pin hole (gas porosity) usual.The degree of supersaturation reached before bubble hydrogen is formed is the function of the number of bubble hydrogen forming core, and oxide and other slag inclusiones are then in the effect of bubble core.
Under general conditions of manufacture, particularly in thick large sand-cast, be difficult to the generation avoiding pin hole.Smelting and cast aluminum alloy in the atmosphere that relative moisture is large, the pin hole in foundry goods is especially serious.Here it is we usually someone feels puzzled always less than the time aluminium alloy castings needle pore defect of rainy humidity reason in dry season aborning.
In general, for aluminum alloy, if crystallization range is comparatively large, then the probability producing netted pin hole is also just much bigger.This is because under general Foundry Production condition, foundry goods has wide solidification temperature range, aluminum alloy is made easily to form flourishing dendritic sgegregation.Phase after solidification, the residual aluminum liquid of dendritic sgegregation gap portion may completely cut off mutually, be present among the approximate slight space closed respectively, the hydrostatic pressure being subject to external atmospheric pressure and alloy liquid due to them is less, vacuum (Feeding channel gets clogged) to a certain degree can be formed when the further cooling meat of residual aluminum liquid, thus make oversaturated hydrogen in alloy separate out and form pin hole.
Be fatal for these pore net nets valve body, be easy to runner hole is punctured.
In addition, processing tool not suitable mutually in prior art, can realize processing well.
Model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of power unit valve block assembly.
The utility model solves the technological scheme that its technical problem adopts: a kind of power unit valve block assembly, comprises valve block and frock, and described valve block is square, and described frock is suitable square mutually with valve block, and described valve block is made up of T6061 section bar aluminium.
According to another embodiment of the present utility model, comprise described frock four limit end face further and be provided with the fastening piece be made up of counterbore and through hole two sector hole.
The beneficial effects of the utility model are, the utility model adopts T6061 section bar aluminium can reduce the scrappage of product, and provides processing tool suitable mutually, improves the stability of power unit, makes product appearance more attractive in appearance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model frock.
Fig. 2 is the structure side view of the utility model frock.
Fig. 3 is the structural representation of the utility model valve block.
In figure 1, valve block, 2, frock, 21, fastener hole.
Embodiment
As shown in Figure 1, 2, 3, a kind of power unit valve of the utility model block assembly, comprise valve block 1 and frock 2, valve block 1 is positioned at frock 2, and described valve block 1 is square, described frock 2 is suitable square with valve block 1 phase, frock 2 four limit end face is provided with the fastener hole 21 be made up of counterbore and through hole two sector hole, and wherein, through-hole diameter is 8 ~ 11mm, counter bore hole diameters is 15mm, the dark 15mm in footpath.
Valve block 1 material of the present utility model adopts T6061 section bar aluminium, adopts T6061 section bar aluminium can reduce the gas mesh of valve block, reduces the scrappage of product, and provide processing tool suitable mutually, improve the stability of power unit, make product appearance more attractive in appearance.
Claims (2)
1. a power unit valve block assembly, comprise valve block (1) and frock (2), valve block (1) is positioned at frock (2), it is characterized in that, described valve block (1) is for square, and described frock (2) is suitable square mutually with valve block (1), and described valve block (1) is made up of T6061 section bar aluminium.
