Abstract
The utility model discloses a reaming tool, which comprises a saddle support, a mandrel (1) and an upper die flat anvil (2). A plurality of first resisting teeth (11) are axially distributed on the mandrel (1), a first resisting groove (12) is formed between each two adjacent first resisting teeth (11), and the first resisting teeth (11) are distributed along the peripheral direction of the mandrel (1). The resisting grooves are designed on the mandrel according to characteristics of ring forging metals during ring expansion, contact area of a forging ring with a mandrel is enlarged, flow direction of deforming metals is changed during forging, metals can be limited to flow along a tangent direction, the metals are driven to flow axially, and thereby axial performance (tension and impact toughness) of the forging ring is improved evidently, is far superior to radial performance, and reaches or close to tangent performance. The axial performance of the reaming tool as compared with the national military or American standard ASTM247 is improved by 40% to 80%.
Description
Technical field
The utility model relates to the forging-ring technical field of forging, particularly a kind of reaming tool.
Background technology
Forging and molding is meant metal is applied external force, makes metal produce plastic deformation, changes the shape and size of blank, and improves its interior tissue and mechanical property, obtains the blank or the part forming processing method of definite shape, size and performance.Forging and molding and drawing are called for short forging and pressing, belong to the part of stress metal method for producing.
Adopt the reaming mode of traditional saddle support, plug, flat anvil, the forging-ring contact-making surface is the plane, and stiction is little, and metal is easy to flow to tangential direction, so the tangential performance of forging-ring is the highest, and radial performance is taken second place, and axial property is minimum.
In addition, for large-scale forging-ring, the particularly diameter forging-ring greater than two meters, utilize the reaming of transmission reaming tool to need two fire to finish at least, the reaming cycle is long.
The utility model content
In view of this, the utility model provides a kind of reaming tool, to improve the axial property of forging-ring.
For achieving the above object, the utility model provides following technical scheme:
A kind of reaming tool, comprise saddle support, plug and patrix flat anvil, its axial distribution of described plug upper edge has the first resistance tooth, and the described first resistance tooth is a plurality of, form the first resistance groove between the adjacent two first resistance teeth, a plurality of described first resistance teeth distribute along the circumferencial direction of described plug.
Preferably, in above-mentioned reaming tool, a plurality of described first resistance teeth evenly distribute along the circumferencial direction of described plug.
Preferably, in above-mentioned reaming tool, the described first resistance tooth is the wheel dentation of gear.
Preferably, in above-mentioned reaming tool, the described patrix flat anvil heart and forging-ring contact position therein is provided with a plurality of second resistance teeth, forms the second resistance groove between adjacent two described second resistance teeth.
Preferably, in above-mentioned reaming tool, a plurality of described second resistance teeth are parallel to each other.
Preferably, in above-mentioned reaming tool, the described second resistance tooth is the wheel dentation of gear.
From above-mentioned technical scheme as can be seen, the characteristics of the utility model forging-ring metal during according to ring expansion, plug is designed, designed the resistance groove, increase the contact area of forging-ring and plug, deformable metal flows to when having changed forging, help retraining metal and flow, promote metal to axial flow, thereby significantly improve the forging-ring axial property to tangential, make axial property (pulling force and impact flexibility) substantially exceed radial performance, reach or approaching tangential performance.Compare with national military standard or U.S. mark ASTMB247, can make axial property improve 40%-80%.
In addition, compare and the conventional tool reaming, reaming can be finished by a fire, shortens the production cycle, cuts down the consumption of energy, and reduces cost; Because contact area increases, unit are is subjected to force intensity when reducing reaming, and strengthen the service life that can make tool.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The structural representation of the plug that Fig. 1 provides for the utility model embodiment;
The structural representation of the patrix flat anvil that Fig. 2 provides for the utility model embodiment;
Fig. 3 for the utility model embodiment provide utilize the reaming tool reaming time structural representation.
The specific embodiment
The utility model provides a kind of reaming tool, to improve the axial property of forging-ring.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1-Fig. 3, the structural representation of the plug that Fig. 1 provides for the utility model embodiment; The structural representation of the patrix flat anvil that Fig. 2 provides for the utility model embodiment; Fig. 3 for the utility model embodiment provide utilize the reaming tool reaming time structural representation.
The reaming tool that the utility model provides, comprise saddle support, plug 1 and patrix flat anvil 2, its axial distribution of described plug 1 upper edge has the first resistance tooth 11, the described first resistance tooth 11 is a plurality of, form the first resistance groove 12 between the adjacent two first resistance teeth 11, a plurality of described first resistance teeth 11 distribute along the circumferencial direction of described plug 1.
The characteristics of the utility model forging-ring metal during according to ring expansion, plug is designed, designed the resistance groove, increase the contact area of forging-ring 3 and plug 1, and first resistance tooth 11 along the axial distribution of plug 1, has certain guide effect so metal flowed to axial direction, deformable metal flows to when having changed forging, helping retraining metal flows to tangential, promote metal to axial flow, thereby significantly improve the forging-ring axial property, make axial property (pulling force and impact flexibility) substantially exceed radial performance, reach or approaching tangential performance.Compare with national military standard or U.S. mark ASTMB247, can make axial property improve 40%-80%.
A plurality of described first resistance teeth 11 preferably evenly distribute along the circumferencial direction of described plug 1.The first resistance tooth 11 is the wheel dentation of gear.
