Description

Novel ring rolling plug of integral type

The technical field is as follows:

the utility model relates to a technical field of ring rolling equipment, more specifically say and relate to a novel ring rolling plug of integral type.

Background art:

the rotary forging method for making the required ring-shaped member by gradually enlarging the diameter of the ring-shaped blank in the hole pattern formed by the rolling roller and the core roller and forming the ring-shaped blank is also called reaming or rolling. The core roll is also called as a core rod for short, the structure of the existing rolling roll and core roll when rolling a bearing ring is shown as figure 1, the core rod, the rolling roll 2, a baffle plate 3 and the bearing ring 4 are arranged, a slot 31 is formed on the baffle plate 3, the core rod is shown as figure 2 and comprises a conical rod body 1, a transition rod body 11 'with the right end of the conical rod body 1 gradually reduced, a cylindrical positioning rod 12' is formed at the right end of the transition rod body 11 ', a conical rolling shaft 13' is formed at the right end of the positioning rod 12 ', when rolling the shaft ring 4, the baffle plate 3 needs to be moved, the positioning rod 12' of the rolling roll 2 is inserted into the slot 31 of the baffle plate 3, so that the bearing ring can abut against the baffle plate 3, but in the rolling process, the baffle plate 3 and the baffle plate need to be moved, and when the rolling core rod with different sizes is adopted, the baffle plate 3 opposite to the rolling roll plate needs to be replaced and installed, the processing is troublesome.

The utility model has the following contents:

the utility model aims at providing a novel ring rolling plug of integral type to being not enough of prior art, and its integrated into one piece with baffle structure and plug does not need the baffle to feed the process of returning back, can improve ring rolling efficiency.

The utility model provides a novel ring rolling plug of integral type, includes the toper barred body of ring rolling plug, and the right-hand member shaping of toper barred body has the circular shape to keep off the dish, and the central shaping of keeping off a set right-hand member face has the columniform to extend the stick, and the right-hand member shaping of extending the stick has conical ring rolling stick.

Preferably, the diameter of the outer wall of the left end of the conical rod body is smaller than that of the outer wall of the right end of the conical rod body.

Preferably, a threaded hole at the bottom is formed in the left end face of the tapered rod body, and the central axis of the threaded hole at the bottom coincides with the central axis of the tapered rod body.

Preferably, the central axes of the rolling rod, the extending rod, the baffle disc and the conical rod body are in the same straight line.

Preferably, the conical angle of the rolling rod is larger than that of the conical rod body.

Preferably, the maximum diameter of the rolling rod is smaller than the diameter of the outer wall of the baffle disc, and the length of the rolling rod is larger than that of the extension rod; the diameter of the extension rod is equal to the minimum diameter of the rolled rod.

The beneficial effects of the utility model reside in that:

1. the baffle plate structure and the core rod are integrally formed, the baffle plate feeding and returning process is not needed, and the rolling efficiency can be improved.

2. The core rod adopted by the rolling device does not need to be externally provided with a baffle, so that the core rod is replaced when replaced, and the rolling assembly is convenient to install.

Description of the drawings:

FIG. 1 is a schematic structural view of a conventional core rod during rolling;

FIG. 2 is a schematic structural view of a conventional mandrel;

FIG. 3 is a schematic three-dimensional structure of the present invention;

FIG. 4 is a schematic partial sectional view of the present invention;

fig. 5 is a schematic structural view of the present invention during rolling.

In the figure: 1. a tapered rod body; 11. a catch tray; 12. an extension bar; 13. rolling and expanding the rods; 14. a bottom threaded hole; 11', a transition rod body; 12', a positioning rod; 13', rolling and expanding the shaft; 2. rolling a roller; 3. a baffle plate; 31. a slot; 4. and (4) bearing rings.

The specific implementation mode is as follows:

example (b): as shown in fig. 3 to 5, the novel integrated ring rolling core rod comprises a conical rod body 1 of the ring rolling core rod, a circular blocking disc 11 is formed at the right end of the conical rod body 1, a cylindrical extension rod 12 is formed at the center of the right end face of the blocking disc 11, and a conical ring rolling rod 13 is formed at the right end of the extension rod 12.

Preferably, the diameter of the outer wall of the left end of the tapered rod body 1 is smaller than that of the outer wall of the right end of the tapered rod body 1.

Preferably, a threaded bottom hole 14 is formed in the left end face of the tapered rod body 1, and the central axis of the threaded bottom hole 14 coincides with the central axis of the tapered rod body 1.

Preferably, the central axes of the rolling rod 13, the extension rod 12, the baffle disc 11 and the conical rod body 1 are on the same straight line.

Preferably, the conical angle of the rolling rod 13 is larger than that of the conical rod body 1.

Preferably, the maximum diameter of the rolled bar 13 is smaller than the diameter of the outer wall of the baffle disc 11, and the length of the rolled bar 13 is larger than that of the extension bar 12; the diameter of the extension rod 12 is equal to the minimum diameter of the rolled rod 13.

The working principle is as follows: the utility model relates to an integral type's novel ring rolling plug, the main technical characterstic in that of the ring rolling plug of its adoption will be the baffle 3 structure of original disconnect-type, with the structure integrated into one piece of preceding ring rolling plug, realize being equipped with on the ring rolling plug and keep off a set 11 structure to do not need baffle 3, thereby conveniently ring rolling processing.

The examples are intended to be illustrative, but not limiting, of the invention. The embodiments can be modified by those skilled in the art without departing from the spirit and scope of the present invention, and therefore, the scope of the present invention should be determined by the appended claims.
