In this way, the utility model discloses thin wall annular forging's core roller frock has realized that the radial ring rolls of numerical control effectively shortens the interval of home roll and core roller in the rolling process, improves the big and ovality of surplus of thin wall ring piece, has alleviateed the work load of the duty cycle and the lathe of equipment, compares with the traditional approach and has practiced thrift the cost, has guaranteed the quality and the efficiency of product, has improved the qualification rate of product.
Description
Technical field
The utility model relates to circular thin-wall forging production technical field, particularly relates to a kind of core roller frock of circular thin-wall forging.
Background technology
Thin-walled ring is mainly used in all kinds of seamless ring production such as bearer ring, gear ring, flange ring, train wheel, wind electricity tower.
The rigidity of circular thin-wall forging is poor, high and have certain cross sectional shape to dimension precision requirement, very easily produces distortion, and be difficult to processing and meet required precision, had a strong impact on product quality, thus thin-walled ring becomes the large difficult point of one in rolling ring.
China generally adopts to this type of thin-walled ring the method that traditional increase thin-walled ring wall is thick at present, but the invisible production cycle adding the cost of raw material and equipment in its manufacture, make whole production cost very high, especially when thin-walled ring is produced in batches, cost expenses is larger.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of core roller frock of circular thin-wall forging, achieve the spacing that the radial ring rolls of numerical control effectively shortens home roll and core roller in the operation of rolling, improve the large and ovality of the surplus of thin-walled ring, alleviate the work period of equipment and the workload of lathe, cost has been saved compared with conventional method, ensure that quality and the efficiency of product, improve the qualification rate of product.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the core roller frock providing a kind of circular thin-wall forging, comprise: special-shaped core roller and core roll sleeve mold, described core roll sleeve mold is a tight fit on special-shaped core roller, the external diameter of described special-shaped core roller is provided with place's step and four uniform the first keyways, described core roll sleeve mold comprises upper module and lower module, the internal diameter of described upper module is provided with the second keyway matched with the first keyway, and flat key is located in the first keyway and the second keyway and core roll sleeve mold and special-shaped core roller is linked together.
In the utility model preferred embodiment, described upper module and lower module are linked together by concavo-convex location structure.
In the utility model preferred embodiment, the circumference of described upper module and lower module is fixed by securing member, and described securing member is full tooth screw rod.
In the utility model preferred embodiment, the center of described upper module and lower module is fastenedly connected by straight pin.
In the utility model preferred embodiment, be connected by screwed hole between described flat key with special-shaped core roller, in described screwed hole, key pin be installed.
In the utility model preferred embodiment, described flat key is connected by upper molded plate with between upper module.
The beneficial effects of the utility model are: the core roller frock of the utility model circular thin-wall forging achieves the spacing that the radial ring rolls of numerical control effectively shortens home roll and core roller in the operation of rolling, improve the large and ovality of the surplus of thin-walled ring, alleviate the work period of equipment and the workload of lathe, cost has been saved compared with conventional method, ensure that quality and the efficiency of product, improve the qualification rate of product.
