Abstract
The utility model relates to a brushless motor bracket blank which comprises a round-sleeve-shaped bracket body. An inner hole of the bracket body is successively composed of an upper section, a middle section and a lower section along the radial direction, wherein the upper section, the middle section and the lower section belong to an integrated structure. A step structure is arranged outside the bracket body and divides the bracket body into a large outer diameter section and a small outer diameter section. An annular flash which extends outward along the radial direction is arranged outside the large outer diameter section of the bracket body. The depth of the inner hole of the upper section is 45mm. The depth of the inner hole of the middle section is 13mm. The depth of the inner hole of the lower section is 15mm. A brushless motor bracket semi-finished product which is processed with the brushless motor bracket blank provided by the the utility model has the advantages of low production cost and high qualification rate.
Description
Technical field
The utility model relates to a kind of brushless motor support blank.
Background technology
Automobile-used brushless motor support is the weight part in the generator, and its existing manufacturing process is: first the brushless motor support blank is forged semi-finished product at friction press, be machined into finished product with numerically controlled lathe again.The half-finished Forging Technology of existing brushless motor support is: with the brushless motor support blank at 1000T friction press finish forge → red punching → air cooling to normal temperature → cold-trim(ming).The brushless motor support blank of existing structure must use large-tonnage friction press finish forge, causes can occurring the endoporus port and produce the angle of collapsing in the course of processing, affects semi-manufactured goods quality, scrappage is high, in addition, owing to forge at main equipment, cause the die life of blank about 1500; And the cutting stock weight of blank is laid particular stress on (2.54kg), the waste raw material, and can vertically produce the thin skin overlap that height differs at blank during cold-trim(ming), the rough turn operation in road after the impact, cause the cost of charp tool higher, improve so must start with from blahk structure, to reduce half-finished production cost.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of low with its brushless motor support semi-finished product production cost that is processed into, the brushless motor support blank that qualification rate is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of brushless motor support blank, comprise the round casing rack body, the endoporus of this rack body radially is made of epimere, stage casing and the hypomere of integrative-structure successively along it, the described rack body outside is provided with a stage structure it is divided into big outer diameter section and small outer diameter section, the big outer diameter section outside of described rack body has the annular overlap that extends radially outwardly along it, the degree of depth of described epimere endoporus is 45mm, the degree of depth of stage casing endoporus is 13mm, and the degree of depth of hypomere endoporus is 15mm.
Described annular overlap is positioned at 1/3rd places near its port of rack body big outer diameter section.
The big outer diameter section of described rack body is positioned at the same end of epimere endoporus.
Beneficial effect: this brushless motor support blank can be on 630 tons of friction presses finish forge, die life, the blank cutting stock weight tapered to 2450g by 2540g about 5000, the 90g that saves material has reduced the semi-finished product production cost; Produce at the endoporus port angle of not collapsing during finish forge, and blank vertically do not have the thin skin overlap to produce at it after cutting edge yet, good with its semi-manufactured goods quality that is processed into, qualification rate is high.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the structural representation of existing brushless motor support blank.
Wherein: 1, rack body; 11, endoporus; 111, epimere; 112, stage casing; 113, hypomere; 12, stage structure; 13, annular overlap.
Embodiment
A kind of brushless motor support blank as shown in Figure 1, comprise round casing rack body 1, the endoporus 11 of this rack body 1 radially is made of epimere 111, stage casing 112 and the hypomere 113 of integrative-structure successively along it, the degree of depth of described epimere endoporus 111 is 45mm, the degree of depth of stage casing endoporus 112 is 13mm, and the degree of depth of hypomere endoporus 113 is 15mm.
Described rack body 1 outside is provided with a stage structure 12 it is divided into big outer diameter section and small outer diameter section, described big outer diameter section is positioned at epimere endoporus 111 same ends, the big outer diameter section outside of described rack body 1 has the annular overlap 13 that extends radially outwardly along it, this annular overlap 13 is positioned at 1/3rd places near its port of big outer diameter section, and the downside of this annular overlap 13 is die joint.
Should be appreciated that specific embodiment described above only is used for explaining the utility model, and be not used in restriction the utility model.The apparent variation of being extended out by spirit of the present utility model or change still are among the protection range of the present utility model.
