Accompanying drawing explanation
Fig. 1 is the structural representation of the detachable core roller establishing the ring forging of annular boss to forge for inwall lower end described in the utility model.
Fig. 2 is the structural representation that the ring forging of annular boss is established in inwall lower end.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As shown in Figure 1, for the detachable core roller that inwall lower end establishes the ring forging of annular boss to forge, comprise mandrel 1, mandrel 1 is set with mandrel cover die 2, mandrel cover die 2 and mandrel 1 are by key transmission, mandrel 1 above mandrel cover die 2 is set with positioning shaft sleeve 3, lower end and the mandrel cover die 2 of upper positioning shaft sleeve 3 lean, mandrel 1 below mandrel cover die 2 is set with lower positioning shaft sleeve 4, upper end and the mandrel cover die 2 of lower positioning shaft sleeve 4 lean, mandrel 1 above upper positioning shaft sleeve 3 is provided with annular groove, anchor ear 5 is embraced on mandrel 1 after snapping in annular groove, the lower end abutment of anchor ear 5 lives in the upper end of positioning shaft sleeve 3, mandrel 1 below lower positioning shaft sleeve 4 is provided with supporting boss 6, lower positioning shaft sleeve 4 is subject to the supporting of supporting boss 6, the lateral profile of mandrel cover die 2 is from top to bottom successively by first face of cylinder 21, rounding table top 22 is coaxially arranged to an entirety, wherein the maximum gauge of rounding table top 22 equals the diameter on first face of cylinder 21, the lateral profile of lower positioning shaft sleeve 4 is second face of cylinder 41, the minimum diameter of rounding table top 22 equals the diameter on second face of cylinder 41, first face of cylinder 21, rounding table top 22, second face of cylinder 41 can be used for the inwall of rolling ring forging.Mandrel cover die 2, upper positioning shaft sleeve 3, lower positioning shaft sleeve 4 is all dismountable on mandrel 1, when the ring forging of annular boss is established in the inwall lower end of rolling different size, do not need the core roller preparing sizes, on mandrel 1, only more need finish changing the mandrel cover die 2 of corresponding size, upper positioning shaft sleeve 3, the forging of the ring forging of annular boss is established in the inwall lower end that lower positioning shaft sleeve 4 just can be used for different size, mandrel cover die 2, upper positioning shaft sleeve 3, the comparison of lower positioning shaft sleeve 4 is simple, fast, and cost of manufacture is not high yet, thus greatly reduce production cost, also production efficiency is substantially increased.
