Abstract

The invention discloses a mandrel tool of a thin-walled annular forge piece. The mandrel tool comprises a special-shaped mandrel and a mandrel sleeve mold. The mandrel sleeve mold is arranged on the special-shaped mandrel in a close fit mode. The outer diameter position of the special-shaped mandrel is provided with a step and four first key grooves distributed evenly. The mandrel sleeve mold comprises an upper mold block and a lower mold block. Second key grooves matched with the first key grooves are formed in the inner diameter part of the upper mold block. Flat keys are arranged in the first key grooves and the second key grooves so that the mandrel sleeve mold and the special-shaped mandrel can be connected together. In this way, by means of the mandrel tool, the distance between a main roller and the mandrel is effectively decreased in the rolling process of a numerical control radial ring roll, the big margin and ovality of thin-walled ring pieces are improved, and the working cycle of the device and the workloads of a machine tool are reduced; compared with a traditional method, cost is saved, quality and efficiency of the product are ensured, and the product percent of pass is increased.

Technical field
The present invention relates to circular thin-wall forging production technical field, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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 described 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 a preferred embodiment of the present invention, described upper module and lower module are linked together by concavo-convex location structure.
In a preferred embodiment of the present invention, the circumference of described upper module and lower module is fixed by securing member, and described securing member is full tooth screw rod.
In a preferred embodiment of the present invention, the center of described upper module and lower module is fastenedly connected by straight pin.
In a preferred embodiment of the present invention, be connected by screwed hole between described flat key with special-shaped core roller, in described screwed hole, key pin be installed.
In a preferred embodiment of the present invention, described flat key is connected by upper molded plate with between upper module.
The invention has the beneficial effects as follows: the core roller frock of circular thin-wall forging of the present invention 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.
