Abstract
The utility model provides a spline shaft forging mould overlap groove. The overlap groove sets up the marginal round at open forging mould die cavity, bridge portion and storehouse portion including the overlap groove, and bridge portion and storehouse portion intercommunication form the cavity that the overlap was filled, the cross sectional shape in overlap groove for the distortion shape, specifically buckle into 95 for bridge portion 110 the turn type cavity of degree angle sets up the bridge part for income oral area and connecting portion, income oral area level, the terminal formation resistance wall of oral area is being gone into to connecting portion, and the diameter of connecting portion is lighter than the diameter into the oral area, connecting portion and storehouse portion intercommunication, storehouse portion also is the level setting. The utility model discloses simple structure can reduce the spline shaft overlap shape in forging and pressing time, reduces the waste of material, has reduced follow -up initial allowance, reduction in production cost.
Description
Technical field
This utility model belongs to forging and stamping technical field of processing equipment, is specifically related to a kind of slip shaft yoke mould for forging flash gutters.
Background technology
Slip shaft yoke is one of primary drive part on automobile, it it is a kind of major axis band fork forgings, shape and structure is complicated, changes of section is big, fork forge piece is most widely used at present is to have flash gutters die forging, traditional moulds structure produces slip shaft yoke stock utilization and is usually no more than 75%, and material cost is the principal element constituting forging cost.
One of principal element affecting metal forming when the size of flash gutters and pattern are die forgings, the design topmost height determining that bridge portion of flash gutters and width.Blank is when the press-in of die forging type intracavity shapes, in blank metal everywhere due to stressing conditions difference respectively to axially and radially flowing, often a separating surface changed is had in a flash in blank, interfacial position is depended on axially and Radial Flow resistance, overlap bridge portion utilizes upper and lower contact surface frictional resistance to stop drain metal exactly, forces metal to be full of die cavity.
In view of the situation, need to be adjusted by mould overlap bridge storehouse portion architecture, make stock utilization improve, and reduce subsequent mechanical allowance.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, there is provided a kind of simple in construction, it is possible to reduce overlap shape when slip shaft yoke forging and stamping, reduce the waste of material, decrease subsequent mechanical allowance, reduce the slip shaft yoke mould for forging flash gutters of production cost.
This utility model solves its technical problem and be the technical scheme is that
Slip shaft yoke mould for forging flash gutters, being arranged on edge one circle of open type forge die die cavity, include bridge portion and the storehouse portion of flash gutters, bridge portion connects with storehouse portion, form the cavity that overlap is filled, it is characterized in that, the cross sectional shape of described flash gutters is distorted shape, and specially bridge portion is bent into the turn-type cavity of 95-110 degree angle, it is inlet portion and connecting portion by bridge portion, inlet portion is horizontally disposed with, and connecting portion forms resistance wall at inlet portion end, and the diameter of connecting portion is less than the diameter of inlet portion；Described connecting portion connects with storehouse portion, and storehouse portion is also for being horizontally disposed with.
In such scheme, described inlet portion, connecting portion, the turning site in storehouse portion, it is fillet smooth structure.
In such scheme, the axis of described inlet portion is contour with the overlap edge line of mold cavity, inlet portion centered by axis, up-down structure and area equation.
Of the present utility model mainly provide the benefit that:
This utility model simple in construction, it is possible to reduce overlap shape when slip shaft yoke forging and stamping, reduce the waste of material, decrease subsequent mechanical allowance, reduce production cost.
Accompanying drawing explanation
Fig. 1 is this utility model example structure global sections figure
In figure: 1 mold cavity, Bridge 2 portion, 3 storehouse portions, 4 inlet portions, 5 connecting portions.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model embodiment is further described:
Slip shaft yoke mould for forging flash gutters as shown in Figure 1, it is arranged on edge one circle of open type forge die die cavity 1, include bridge portion 2 and the storehouse portion 3 of flash gutters, bridge portion 2 connects with storehouse portion 3, form the cavity that overlap is filled, the cross sectional shape of described flash gutters is distorted shape, it is specially bridge portion 2 and is bent into the turn-type cavity of 110 degree of angles, bridge portion 2 is divided into inlet portion 4 and connecting portion 5, inlet portion 4 is horizontally disposed with, connecting portion 5 forms resistance wall at inlet portion end, and the diameter of connecting portion 5 is less than the diameter of inlet portion 4；Described connecting portion 5 connects with storehouse portion 3, and storehouse portion 3 is also for being horizontally disposed with.
In the present embodiment, described inlet portion 4, connecting portion 5, the turning site in storehouse portion 3, it is fillet smooth structure.
In the present embodiment, the axis of described inlet portion 4 is contour with the overlap edge line of mold cavity 1, inlet portion 4 centered by axis, up-down structure and area equation.
Protection domain of the present utility model is not limited to the above embodiments, it is clear that those skilled in the art can carry out various change and deformation without deviating from scope and spirit of the present utility model to this utility model.If these are changed and deformation belongs in the range of this utility model claim and equivalent technologies thereof, intention the most of the present utility model also comprises these and changes and deformation.
