Description
Technical field:
The present invention relates to technical field of forging, more specifically to the progressive die used by the forging of a kind of tapered roller bearing ring
Tool.
Background technology:
As shown in Figure 1, existing tapered roller bearing ring forging production technique is: 1, by materials and parts A1 by preforming tool punching press
Become preformed member A2,2, preforming pieces A2 is struck out profiled member A3 by mould, 3, profiled member is led in the cold state
Cross separation punching die strike out outer ring A4, inner ring A5 and separate block A6.Its weak point is: it needs to consider when design
Inner ring external diameter rib clamping face straight flange, the straight flange of external diameter rib clamping face is not less than 0.7mm.I.e. when punching press, on profiled member A3
Inner ring diameter D1 be 40.3mm, and the inner ring of finished product inner ring A5 to face diameter D2 directly be 39.7mm, this is mainly in cold conditions state
Under when stamping out finished product outer ring A4, inner ring A5 and separate block A6, inner ring A5 to go out separation block A6 when molding, so inner ring A5
Outer diameter face molding can be by bigger impulsive force, so this design is 40.3mm due to the inner ring diameter D1 on profiled member A3
The i.e. inner ring diameter of profiled member A3 leaves surplus, and during such blanking, the weight of materials and parts A1 is 307 grams, and its blanking is more, so increases
Add the consumption of material, add production cost.
In order to save consumption of materials, we determine to change production technology, need to redesign mould, and the present invention is therefrom
Produce.
