Advantage of the present utility model is: by the extruding drift that is joined successively by fixed part and the portion of exerting pressure, be pressed on the Extruding die of being formed by cylindrical upper section, conical middle part and cylindrical lower portion, once stamp out bearing ring, simple in structure, save time, manpower.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of bearing ring.
Fig. 2 is the cutaway view of the mould of a kind of impulse bearing lasso of the utility model.
[specific embodiment]
See also shown in Figure 2ly, a kind of mould 100 of impulse bearing lasso, this mould 100 comprise that one is installed on extruding drift 1 and the Extruding die 2 that arranges in this extruding drift 1 below on the stamping machine; Described extruding drift 1 comprises a fixed part 11 and that joins the successively portion 12 that exerts pressure from top to bottom; Described fixed part 11 is fastenedly connected with this stamping machine (not shown); The described portion 12 that exerts pressure is an inverted cone post; The vertical central axis of described Extruding die 2 is provided with a through hole 21 that supplies this portion 12 that exerts pressure to shuttle back and forth; Described through hole 21 comprises top 211, middle part 212 and the bottom 213 that sets gradually from top to bottom; Described top 211 and bottom 213 are cylindrical; Described middle part 212 is a turbination, the diameter of phi of these 212 upper ends, middle part
1≤ described upper part diameter Φ
2, the diameter of phi of this lower end, middle part
3The diameter of phi of≤described bottom
4Described top, middle part and bottom three's central lines.The round iron post that burns red hollow is placed on the through hole 21 that is joined successively by top 211, middle part 212 and bottom 213, pushes this through hole 21 downwards by the portion of exerting pressure 12, once finish the processing of bearing ring.
Described fixed part 11 comprises one first cylinder 111, one first awl cylinder 112 and one second cylinder 113 that joins successively from top to bottom; The diameter of phi of described first cylinder 111
5The diameter of phi of＞this second cylinder 113
6The diameter of phi of the described first awl cylinder 112 upper ends
7≤ this first cylindrical diameter of phi
5, and the diameter of phi of this first awl cylinder lower end
8≤ this second cylindrical diameter of phi
6This design makes lower end (the i.e. second cylinder 113) area of fixed part 11 less, more can concentrate the application of force to the portion of exerting pressure 12.
The utility model will push drift and be installed on the stamping machine when using, and Extruding die is arranged at the below of this extruding drift, the two central lines of described extruding drift and Extruding die; Start stamping machine, the round iron post of red hollow is burnt in placement on Extruding die, and the extruding drift rolls the red round iron post of burning on the Extruding die downwards, after the upper end of round iron post is extruded the drift extruding, to the both sides expansion formation raceway of through hole; The extruding drift is about to burn red round iron post and is rolled into bearing ring in Extruding die after upwards playbacking, and once finishes processing, saves time and human-saving.
Though more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
