Technical Field

The utility model relates to the technical field of roller structures, in particular to a special-shaped roller structure of a radial and axial ring rolling machine.

Background

As shown in FIG. 1, a medium-large radial-axial ring rolling machine is generally used for producing rectangular ring parts, and a ring rolling machine manufacturer designs a higher roller to be suitable for rolling products with different outer diameters and different heights, so that the size and the weight of the roller are large. When the rectangular ring is rolled, the influence is not great because the roller does not need to be replaced. However, in practical situations, the ring rolling machine is often used for rolling various special-shaped products, so that the design of opening cavities of the roller is required, and due to the large size of the roller, the manufacturing cost of the roller die is high, the manufacturing of the die is difficult, and the difficulty and the cost of replacing and repairing the roller at the later stage are also high. Most of the special-shaped pieces are partially special-shaped, and the height dimension is not high, so that the manufacturing cost of the whole roller is consumed due to the production of a small number of special-shaped pieces, and the cost performance is not high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides the special-shaped roller structure of the radial and axial ring rolling machine, which has the advantages of simple and reasonable structure, low investment cost and capability of reducing the production and manufacturing difficulty and is suitable for various ring rolling structures.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows:

the utility model provides a radial and axial ring rolling machine dysmorphism roll structure, cup joints outside the pivot, and its axial displacement is restricted by the flange in both ends, cuts apart into a plurality of roller sections along the axial, and the terminal surface of adjacent roller section closely laminates, and the peripheral face of at least one roller section is the machined surface with waiting to process ring rolling work piece structure adaptation.

As a further improvement of the above technical solution:

the roll segment with the machined surface is arranged below the roll segment without the machined surface.

A plurality of roller sections with processing surfaces are arranged from top to bottom according to the structure of the ring rolling workpiece to be processed.

The outside diameter of the rib adjacent to the roller section with the machined surface is smaller than the outside diameter of the roller section.

The outer diameter of the roll segment without the machined surface is not greater than the outer diameter of the roll segment with the machined surface.

The core roller is in a stepped shaft shape, and the diameter of a shaft section corresponding to the roller section without the processing surface in the core roller is larger than that of the other shaft section.

Compared with the prior art, the utility model has the advantages that:

the special-shaped roller structure of the radial and axial ring rolling machine is sleeved outside the rotating shaft, and the axial movement of the special-shaped roller structure is limited by the flanges at the two ends, so that the stability of the roller is ensured. The roller structure is axially divided into a plurality of roller sections, the end faces of the adjacent roller sections are tightly attached, and the peripheral surface of at least one roller section is a processing surface matched with the structure of the grinding ring workpiece to be processed. Compared with an integral structure, the sectional structure can be split at will, a processing surface is arranged on the roller section matched with the grinding ring workpiece to be processed, and other parts only have a limiting and retaining effect. Therefore, when the corresponding roller is manufactured aiming at the special-shaped rolling ring workpiece structure, only the opening cavity processing is carried out on the partial roller section, the manufacturing mold cost is low, and the processing difficulty is greatly reduced. When the roller structure is replaced and repaired in the later stage, only the roller section at the local part is replaced or repaired, the difficulty is greatly reduced, and the cost performance of the roller structure is greatly improved.

Detailed Description

In order to facilitate understanding of the utility model, the utility model will be described more fully and in detail with reference to the accompanying drawings and preferred embodiments, but the scope of the utility model is not limited to the specific embodiments below.

Example (b):

as shown in fig. 2 and fig. 3, the special-shaped roll structure of the radial and axial ring rolling machine of the present embodiment is sleeved outside the rotating shaft 1, two ends of the special-shaped roll structure are limited by the flanges 2 to move axially, the special-shaped roll structure is divided into a plurality of roll segments 3 along the axial direction, the end surfaces of the adjacent roll segments 3 are tightly attached, and the peripheral surface of at least one roll segment 3 is a processing surface 31 adapted to the structure of a ring rolling workpiece to be processed. Compared with an integral structure, the sectional structure can be randomly split, only the processing surface 31 is arranged on the roller section 3 matched with the grinding ring workpiece to be processed, and other parts only perform limiting and retaining effects. Therefore, when the corresponding roller is manufactured aiming at the special-shaped rolling ring workpiece structure, only the local roller section 3 is processed by opening the cavity, the manufacturing mold is low in cost, and the processing difficulty is greatly reduced. When changing and repairing in the later stage, only change or repair to local roller section 3 can, the degree of difficulty also greatly reduced, very big improvement the price/performance ratio of roll structure.

In this embodiment, the roller section 3 with the processing surface 31 is arranged below the roller section 3 without the processing surface 31, so that the processing position is located at the lower part, the ring rolling workpiece can be supported by the working table surface in the processing process, and the stability of the processing process is improved.

In this embodiment, as shown in fig. 2, when the height of the ring rolling product is low, only one roller section 3 to be used as the processing surface 31 needs to be adopted, and the processing surface 31 of the roller section 3 is a straight surface or a special-shaped surface matched with a special-shaped structure in the ring rolling product. When the height of the mill ring product is high, as shown in fig. 3, a plurality of roll segments 3 with processing surfaces 31 are arranged from top to bottom according to the structure of the mill ring workpiece to be processed.

In this embodiment, the outer diameter of the flange 2 adjacent to the roller section 3 with the machined surface 31 is smaller than the outer diameter of the roller section 3, so that the machined surface 31 protrudes, which is beneficial to the later repair. The outer diameter of the flange 2 is reduced by 30mm compared with the original flange, the thickness is reduced by 20mm, and the material cost is further saved.

In this embodiment, the outer diameter of the roll segment 3 without the machining surface 31 is not larger than the outer diameter of the roll segment 3 with the machining surface 31, so that the material consumption of the part not involved in machining can be reduced, the cost can be reduced, and the stability of the axial position of the roll segment 3 with the machining surface 31 can be ensured.

In this embodiment, the core roll 4 is in a stepped shaft shape, and the diameter of the shaft section of the core roll 4 corresponding to the roll section 3 without the processing surface 31 is larger than the diameter of the other shaft section, that is, the shaft section of the core roll 4 is thickened correspondingly, and meanwhile, the core roll does not interfere with the roll, so that the bending resistance of the core roll 4 is increased, and the strength of the core roll 4 is improved.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-described embodiments. It should be apparent to those skilled in the art that modifications and variations can be made without departing from the technical spirit of the present invention.
