Abstract
The utility model provides an automobile water pump flange plate, which comprises a plate body provided with a shaft hole. A projecting circular ring is arranged in the middle of the plate body; a central hole of the circular ring is overlapped with the shaft hole; and the plate body is pressed and formed by means of powder metallurgy. The flange plate has the advantages that the shaft hole in the middle of the plate body is lengthened by the aid of the projecting circular ring arranged on one side of the plate body so that the flange plate is more convenient to mount, the flange plate is pressed and formed once by means of the powder metallurgy production process, material consumption and processing procedures are decreased, processing difficulty is reduced, the formed flange plate is high in accuracy and fine in uniformity, and product qualification rate and water pump loading qualification rate are increased.
Description
Technical field
The utility model relates to a kind of flange plate that is used for auto pump.
Background technique
The water pump flange plate is one of component important on the auto pump, and it is used to connect water pump cover and outlet conduit, and has better seal.Present water pump flange plate has multiple shape, as circle, cross, triangle etc., be provided with the axis hole that is used for connecting tube at the center of flange plate, all around at the screw that also being provided with of flange plate is used for and water pump cover is fixing, during installation, by flange plate water pump is connected with outlet conduit and gets final product.Present flange plate is when making, be to mill processing mostly by milling machine, with this flange plate is carried out chamfering, polishing circular arc etc., but, because noise is very big in the milling machine course of working, and need operate successively each position to be processed of part man-hour adding, so difficulty of processing is bigger, product percent of pass is also lower.These people have been proposed the technological method of powder metallurgy, it be adopt metal or with metallic dust (or mixture of metallic dust and non-metal powder) as raw material, through being shaped and sintering, make the process engineering of metallic material, compound and all kinds goods.Powder metallurgy has unique chemical to be formed and machinery, physical property, and these performances are can't obtain with traditional casting method.Adopt powder metallurgy forming can directly make porous, half fine and close approaching full dense material and goods, as oil-impregnated bearing, gear, cam, guide rod, cutter etc., be a kind of milling process that do not have less, and it is poly-partially to reduce alloying constituent to greatest extent, eliminates thick, uneven cast structure.
The model utility content
At above-mentioned deficiency of the prior art, the auto pump flange plate that provides a kind of machining accuracy higher, easy for installation is provided the purpose of this utility model.
The technical solution of the utility model: the auto pump flange plate, comprise disk body, on disk body, be provided with axis hole, it is characterized in that be provided with the annulus of projection at the middle part of disk body, the center hole of described annulus overlaps with axis hole; Described disk body is by the powder metallurgy pressing moulding.
Also be provided with equally distributed silk hole on the disk body of the utility model flange plate, disk body and water pump cover can be connected and fixed by the silk hole.And because after adopting powder metallurgy to make disk body, the precision of the chamfering of disk body, circular arc and flatness etc. obviously improves, better tightness is installed the back and is difficult for producing the situation of leaking.
With respect to prior art, the utlity model has following beneficial effect:
Water pump flange plate of the present utility model makes the axis hole at disk body middle part be lengthened out more convenient like this installation by the annulus of projection is set in disk body one side; And flange plate of the present utility model has adopted a compression moulding of production technology of powder metallurgy, the use and the manufacturing procedure of material have been reduced, reduced difficulty of processing, and flange plate precision height, high conformity after the moulding, product percent of pass and water pump entrucking up-to-standard rate improved.
Description of drawings
Fig. 1 is the plan view of the utility model auto pump flange plate;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure, 1-disk body, 2-axis hole, 3-annulus, 4-center hole, 5-silk hole.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, auto pump flange plate of the present utility model comprises circular disk body 1, is provided with axis hole 2 at the center of disk body 1, and described axis hole 2 is a through hole, is used to be communicated with outlet conduit and water pump.Be provided with four silk holes 5 that evenly distribute and be used for connecting bolt on disk body 1, also be provided with the annulus 3 of projection at the middle part of disk body 1, the center hole 4 of described annulus 3 overlaps with axis hole 2, can increase the length of axis hole 2 by annulus 3 is set, more convenient like this installation.In the utility model, what disk body 1 adopted is the powder metallurgy pressing moulding, and it only needs time processing promptly to can be made into adding man-hour, during making noise pollution less, and do not need to operate manually, reduced the production difficulty, help improving product percent of pass.
