Abstract

The utility model discloses a kind of forge piece mold structure for forging revolving parts, described forge piece mold structure comprises: the patrix being provided with core rod, be provided with the counterdie of type groove, wherein, described counterdie comprises: the first counterdie insert and the second counterdie insert vertically overlayed above described first counterdie insert, further, described first counterdie insert and described second counterdie insert are vertically fastenedly connected by securing member.Described forge piece mold structure by arranging combined type counterdie, thus facilitates the high accuracy manufacture of counterdie, reduces the processing and manufacturing difficulty of counterdie, and then effectively can ensure the forging precision of revolving parts.In addition, the forge piece mold structure that the utility model provides significantly can also reduce mold materials.

Description

A kind of forge piece mold structure
Technical field
The utility model relates to mould, specifically relates to a kind of forge piece mold structure.
Background technology
At present, for revolving parts such as the hollow half axles on such as excavator, then usually to be processed by mould die forging.Further, the counterdie forging this type of revolving parts adopts overall manufacture usually.Because the type groove of counterdie is very dark, in the manufacture process of counterdie, according to the metal-cutting machining method of routine, then need the cutting knife bar grown very much, and so, longer cutting guide rod easily because stiff problem produces cutter relieving phenomenon, causes the deficient of counterdie to cut, thus makes the accuracy of manufacture of counterdie can not meet the forging processing request of revolving parts in metal cutting process.
For the problems referred to above, disclose a kind of mode adopting tow sides to carry out machining respectively in prior art, but such processing brings another machining accuracy problem, be namely difficult to the coincidence ensureing tow sides tool setting precision and the origin of coordinates.In addition, because the type groove depth of counterdie is comparatively large, the reason such as wearing and tearing easily because of mould in the forging process of hollow half axle causes scrapping.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of forge piece mold structure with higher forging precision.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of forge piece mold structure, for forging revolving parts, there is such feature, comprise: the patrix being provided with core rod, be provided with the counterdie of type groove, wherein, counterdie comprises: the first counterdie insert and the second counterdie insert vertically overlayed above the first counterdie insert, further, the first counterdie insert and the second counterdie insert are vertically fastenedly connected by securing member.
Further, in the forge piece mold structure that the utility model provides, can also have such feature: the top of the first counterdie insert is provided with annular boss, the second counterdie insert is axially sleeved on the outside of annular boss.
Further, in the forge piece mold structure that the utility model provides, can also have such feature: patrix connects upper plate by carving iron, counterdie connects lower shoe by carving iron.
Further, in the forge piece mold structure that the utility model provides, such feature can also be had: lower shoe is provided with the backing-out punch slided up and down along type groove.
Further, in the forge piece mold structure that the utility model provides, such feature can also be had: patrix setting-in core rod.
Further, in the forge piece mold structure that the utility model provides, such feature can also be had: securing member is bolt or screw.
The good effect that the utility model has on the basis of the above is:
The forge piece mold structure that the utility model provides by arranging combined type counterdie, thus facilitates the high accuracy manufacture of counterdie, reduces the processing and manufacturing difficulty of counterdie, and then effectively ensures the forging precision of revolving parts.In addition, the forge piece mold structure that the utility model provides significantly can also reduce mold materials.
Accompanying drawing explanation
Fig. 1 is that the version of revolving parts in embodiment of the present utility model cuts open schematic diagram.
Fig. 2 be in embodiment of the present utility model forge piece mold structure partly cut open schematic diagram.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed the forge piece mold structure that the utility model provides by reference to the accompanying drawings.
The forge piece mold structure that the present embodiment provides is for forging revolving parts 10 as shown in Figure 1.
As shown in Figure 2, the forge piece mold structure that the present embodiment provides comprises: the patrix 2 being provided with core rod 1, is provided with the counterdie 3 of type groove, and, be formed with the impression 4 of forging revolving parts 10 between patrix 2 and counterdie 3.Concrete, in the present embodiment, counterdie 3 comprises the first counterdie insert 31 and the second counterdie insert 32.
Wherein, the second counterdie insert 32 vertically overlays the top of the first counterdie insert 31, and the top of the first counterdie insert 31 is provided with annular boss 33, and the second counterdie insert 32 is axially sleeved on the outside of annular boss 33.
Further, the first counterdie insert 31 and the second counterdie insert 32 are vertically fastenedly connected by securing member 5.Namely combined type counterdie is formed by the first counterdie insert 31 and the second counterdie insert 32.
Patrix 2 is fixedly connected with upper plate 7 by carving iron 6, and counterdie 3 is fixedly connected with lower shoe 9 by carving iron 8.Upper plate 7 and lower shoe 9 are arranged on forging press.
For the ease of successfully being separated from counterdie easily by the revolving parts of forging molding, in the present embodiment, lower shoe 9 is also provided with the backing-out punch 91 slided up and down along type groove.
Further, in the present embodiment, patrix 2 setting-in core rod 1, relative to patrix and the mold insert structure of integrative-structure, can save mold materials.
In the present embodiment, securing member can be any one in bolt or screw, by tightening or backing out securing member, can realize the first counterdie insert and the fastening of the second counterdie insert and be separated.Be convenient to the maintenance of counterdie.
The forge piece mold structure that the present embodiment provides by arranging combined type counterdie, thus facilitates the high accuracy manufacture of counterdie, reduces difficulty of processing, and then ensures the forging precision of revolving parts.In addition, the forge piece mold structure that the present embodiment provides significantly can also reduce mold materials.
The foregoing is only the utility model preferably example; forge piece mold structure involved by certain the utility model is not merely defined in the structure in the present embodiment; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model descriptions and diagramatic content and apparent change obtain in protection domain of the present utility model.
