Abstract
The utility model relates to powder metallurgical technology, disclose a kind of engine balance bearing housing mould, for shaping engine balance bearing housing, described bearing block comprises a triangular platform flange, described mould comprises patrix and former, described former is formed former band shoulder, arranges a salient point in described former band shoulder, described salient point is positioned at the position of mounting hole of described flange, and the size of described salient point is less than the size of described installing hole.The utility model only redesigns the former of former shaping mould, and all the other moulds can continue to use, and die cost significantly lowers.
Description
Technical field
The utility model relates to powder metallurgical technology, particularly relates to a kind of engine balance bearing housing mould.
Background technology
See accompanying drawing 1, balance shaft bearing seat in automobile engine adopts the method for powder metallurgy to manufacture more and more widely, and most bearings seat 1 has a triangular platform flange 2, this flange is special-shaped asymmetrical design, and this just gives in powder metallurgy actual production and brings a difficult problem.
See accompanying drawing 2, the thickness of bearing block 1 triangular platform flange 2 very thin only 3.4
+ 0.1mm, and perpendicularity requires the tolerance only having 0.05, because this design of part is special-shaped, triangular platform is very thin, distortion in various degree can be produced in part sintering process, and, flange 2 is also wanted machined form installing hole 3, in order to ensure that parts size precision reaches requirement, shaping road sequence must be increased after sintering and ensure.
See accompanying drawing 3,4, the Training system of part for arranging former band shoulder 5 on former 4, and namely part triangular platform reaches required precision by former band shoulder 5 and adjustment shaping patrix drafts.But using in conventional Training system process, because part is overall with triangular platform discontinuity when being subject to the pressure of shaping patrix, triangular platform place can produce in various degree stay distortion (see accompanying drawing 5), cause perpendicularity 0.05 overproof.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of engine balance bearing housing mould, by changing the structure of former band shoulder, compensates distortion during shaping.
The technical scheme that the utility model is taked is:
A kind of engine balance bearing housing mould, for shaping engine balance bearing housing, described bearing block comprises a triangular platform flange, described mould comprises patrix and former, described former is formed former band shoulder, it is characterized in that, in described former band shoulder, a salient point is set, described salient point is positioned at the position of mounting hole of described flange, and the size of described salient point is less than the size of described installing hole.
Further, the thickness of described flange is 3.4
+ 0.1mm, the diameter of described installing hole is 6.6mm, and described salient point is round dot, and the diameter of described salient point is 4mm, and the height of described salient point is 1mm.
The beneficial effects of the utility model are:
(1) only redesign the former of former shaping mould, all the other moulds can continue to use, and die cost significantly lowers;
(2) Making mold is easy, and the process-cycle is short.

Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to the utility model engine balance bearing housing mould.
See accompanying drawing 6,7, engine balance bearing housing mould comprises patrix and former 4, described former 4 is formed former band shoulder 5, and in described former band shoulder, 5 arrange a salient point 6, salient point 6 is positioned at installing hole 3 position of flange, and the size of salient point 6 is less than the size of installing hole.The shaping being realized flange by the structure of former 4 is deformation-compensated.
Part final finished is the through hole that there is a ￠ 6.6 at endoporus center to triangular platform center (centre-to-centre spacing 30 ± 0.2), and this through hole is formed by Drilling operation after shaping.Be the salient point of 30 ± 0.05 in shaping former band shoulder place's increase centre-to-centre spacing, diameter is ￠ 4, height 1mm, its position is just in time consistent with the lead to the hole site of ￠ 6.6 in rear road sequence drilling operating and salient point is less than ￠ 6.6 diameter, object makes the stressed effect causing the triangular platform place staying distortion to play passing rectification originally when part shaping by the salient point on former band shoulder, thus ensure that the thickness of triangular platform and perpendicularity reach drawing requirement, and bore position is overlapping in impression Ze Yuxia road, the triangular platform place sequence drilling operating that salient point causes, diameter of impression is less than through-hole diameter, can remove completely man-hour adding, on part final finished state without any impact.
See accompanying drawing 8, bearing block flange shaping mould comprises patrix 7, former 4, outer counterdie 8, interior counterdie 9 and center die 10, patrix 7 and former 4 and outer counterdie 8, interior counterdie 9 form the shape chamber 11 of bearing block, center die 10 is engaged in the centre bore of patrix 7 and interior counterdie 9, form the central shaft hole of bearing block, part triangle put down right flange be subject to salient point 6 on to power, compensate the distortion of machined and shaping.
In this embodiment, although only done elaboration with the die method improving bearing block flange perpendicularity, should be appreciated that mould of the present utility model also can be used for producing the powder metallurgy product of similar structures.
By the version using mould to increase former band shoulder salient point, part shaping Vee formation platform is stayed metaboly and is significantly improved, size and the depth of parallelism also can reach drawing requirement, and disqualification rate is reduced to less than 3% from original 20%, really achieves production in enormous quantities.
Below be only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
