Abstract
The invention relates to an aluminum valve bar for automobile braking pump and the manufacturing process. The aluminum valve bar for automobile braking pump in invention is characterized in that it comprises slide bar part with triangular section and head part connected with rubber plug and a hard anodic oxidation layer is set on the surface of said valve bar. The manufacturing process is characterized in that the slide bar part is formed by cold extrusion process of aluminum rod; the head part is formed by cutting; after machining the surface of valve bar is treated by hard anodic oxidation. Notable merits of invention are that the first is that the aluminum valve bar is provided with good quality, wear resistance, corrosion resistance after the treatment of hard anodic oxidation; the second is that the section of slide bar of aluminum valve bar is triangle, not only it is provided with good oil passing effect and strong stability but also offset phenomena can not appear in working so that the sealing effect of rubber plug used in cooperation with it is better; the third is that the invention is provided with simple structure, convenient usage and low cost.
Description
Technical field
The present invention relates to a kind of automobile brake pump bar of aluminum valve and manufacturing process thereof.
Background technology
Automobile brake pump on the market normally adopts ironwork with valve lever, get rusty easily, influence result of use, and the aluminium that people were familiar with, after handle through hard anodizing on the surface, have withstanding corrosion, rub resistance, advantage such as durable, therefore adopting bar of aluminum valve is a very good selection as automobile brake pump.
Summary of the invention
The objective of the invention is to provide a kind of automobile brake pump bar of aluminum valve and manufacturing process thereof, this valve lever simple structure is difficult for corrosion, rub resistance, good product quality.
Automobile brake pump of the present invention is characterised in that with bar of aluminum valve: comprise section slide bar portion triangular in shape and the head that is connected with plug, described valve stem surfaces has hard anodizing horizon.
Automobile brake pump of the present invention is characterised in that with the manufacturing process of bar of aluminum valve: described slide bar portion adopts the moulding of aluminium bar cold-extrusion technology, and head carries out the hard anodizing processing to valve stem surfaces through the machinework cutting forming machining after again.
Remarkable advantage of the present invention is: the one, after bar of aluminum valve is handled through hard anodizing, have that quality is good, a rub resistance, resistant to corrosion advantage; The 2nd, section of slide bar of aluminum valve bar is triangular in shape, has not only that oil is effective, the strong advantage of stability, and does not produce shift phenomenon during work, makes the plug sealing effectiveness that is mated use better.
Description of drawings
Fig. 1 is an essential structure scheme drawing of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is a running condition scheme drawing of the present invention.
The specific embodiment
Automobile brake pump of the present invention is characterised in that with bar of aluminum valve: comprise section slide bar portion 1 triangular in shape and the head that is connected with plug 5, described valve stem surfaces has hard anodizing horizon.
In order to help the stable work of valve lever, described head comprises superposed taper round platform 2, is connected in the path quarter butt 3 at middle part and the discoideus body 4 between path quarter butt and slide bar.
Automobile brake pump of the present invention is characterised in that with the manufacturing process of bar of aluminum valve: described slide bar portion adopts the moulding of aluminium bar cold-extrusion technology, head reaches desired size through the machinework cutting forming, again valve stem surfaces is carried out hard anodizing after machining and handle, make valve lever reach wear-resisting wiping resistant to corrosion effect.
Simple structure of the present invention, easy to use, productive costs is low, has bigger application value.
