Abstract
The utility model relates to a combined core roller of a ring rolling machine, which is used for manufacturing special-shaped ring forgings and characterized in that the combined core roller comprises a mandrel provided with a key, one end of the mandrel is provided with a shaft shoulder, the core roller formed by combining at least three roller sheets is sleeved on the mandrel through the key, and the roller sheets are fastened on the shaft shoulder of the mandrel by a fastening nut from one end. The combined core roller is simple in structure, a plurality of roller sheets with different shapes and sizes are combined to form the special-shaped core roller for producing the special-shaped ring forgings, the production cost of the special-shaped ring forgings is reduced, a large number of capitals for mould spare parts are saved, mould preparation period is shortened, and production capacity is improved.
Description
Technical field
The utility model relates to a kind of Ring Rolling Machine, especially relates to a kind of Ring Rolling Machine combination core roller, is used for the manufacturing of forging special-shape ring.
Background technology
Development and intense market competition along with ring rolling spare technology; For economical with materials, reduction postorder cost of processing; Begin to produce interior forging special-shape ring (like Fig. 1), inside and outside forging special-shape ring (like Fig. 2) and outer forging special-shape ring; Especially in large-scale ring rolling spare is produced, practice thrift lot of materials and reduce the postorder cost of processing.In the prior art, on large-scale ring rolling machine, use integrally-built special-shaped core roller usually, as shown in Figure 3; Integral special-shaped core roller 1 ' be structure as a whole; Processing difficulties because the core roller is worked under high temperature, big load condition for a long time, is prone to cause the core roller to damage; Integrally-built special-shaped core roller is scrapped, caused production cost to increase; In addition, for the forging special-shape ring or the urgent document or dispatch of small lot batch manufacture, the special-shaped core roller preparatory period of making special use is longer, and production cost is increased.
The utility model content
The applicant has carried out research and improved to above-mentioned problem, and a kind of Ring Rolling Machine combination core roller is provided, and is simple in structure, the special-shaped core roller of formation capable of being combined, and the production cost of reduction forging special-shape ring shortens the special-shaped core roller preparatory period.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Ring Rolling Machine combination core roller; Comprise mandrel, mandrel is provided with key, and an end of mandrel is provided with the shaft shoulder; The core roller die that is constituted by at least three roller sheets is sleeved on the said mandrel through said key, and clamp nut is fastened on said roller sheet on the shaft shoulder of said mandrel from an end.
Further:
Said roller sheet comprises cylindrical roller sheet, taper type roller sheet and barrel-type roller sheet.
The technique effect of the utility model is:
The disclosed a kind of Ring Rolling Machine combination core roller of the utility model; Simple in structure, the roller sheet through multi-disc difformity size constitutes special-shaped core roller, is used for the production of forging special-shape ring; Reduce the production cost of forging special-shape ring; Practice thrift a large amount of mould spare parts simultaneously and used fund, shortened the mould preparatory period, improved production capacity.
Description of drawings
Fig. 1 is interior forging special-shape ring sketch map.
Fig. 2 is inside and outside forging special-shape ring sketch map.
Fig. 3 is the structural representation of special-shaped core roller of the prior art.
Fig. 4 is the structural representation of the utility model embodiment 1.
Fig. 5 is the structural representation of the utility model embodiment 2.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
As shown in Figure 4, combination core roller comprises mandrel 1, and mandrel 1 is provided with key 2; One end of mandrel 1 is provided with the shaft shoulder 3; The core roller die 4 that is constituted by three cylindrical roller sheets 401 and two taper type roller sheets 402 is sleeved on the mandrel 1, and clamp nut 5 is fastened on three cylindrical roller sheets 401 and two taper type roller sheets 402 on the shaft shoulder 3 of mandrel 1 from an end, and three cylindrical roller sheets 401 and two taper type roller sheets 402 connect mandrels 1 through key 2; When rolling over the ring operation; Three cylindrical roller sheets 401 and two taper type roller sheets 402 rotate with mandrel 1 synchronously, like wherein a certain roller sheet appearance damage, only need change the roller sheet of damage; And need not integral replacing, thereby reduce production costs.
As shown in Figure 5, the core roller die 4 that is constituted by two cylindrical roller sheets 401, two taper type roller sheets 402 and a slice barrel-type roller sheet 403 is sleeved on the mandrel 1, and other are identical with embodiment 1.
Through the combination with cylindrical roller sheet 401, taper type roller sheet 402 and the barrel-type roller sheet 403 of varying number, the roller sheet can be made into multiple height, outside dimension and shape simultaneously, assembles according to the requirement of different rings forging, produces various forging special-shape rings.Available so minimum mould amount satisfies the ring rolling spare production of various special shapes, practiced thrift a large amount of shared funds of mould spare part, has also reduced the time obstacle that the mould preparatory stage brings for scheduling of production and contract execution.
Claims (2)
1. a Ring Rolling Machine makes up the core roller; It is characterized in that: comprise mandrel, mandrel is provided with key, and an end of mandrel is provided with the shaft shoulder; The core roller die that is constituted by at least three roller sheets is sleeved on the said mandrel through said key, and clamp nut is fastened on said roller sheet on the shaft shoulder of said mandrel from an end.
2. according to the described Ring Rolling Machine combination of claim 1 core roller, it is characterized in that: said roller sheet comprises cylindrical roller sheet, taper type roller sheet and barrel-type roller sheet.
