Abstract
The present case is an internal mold for free forging, and it is used for processing the blank, includes: the three core moulds are respectively and closely distributed adjacently to form the inner mould with the circular cross section. The utility model discloses the centre form of the present case of making forms the core that three shape is the same, makes things convenient for the drawing of patterns, and the inner membrance can be made up into to the mandrel of arbitrary three the same specification, and convenient operation, simple structure can solve the problem of being difficult to the drawing of patterns in the actual production process.
Description
Technical Field
The utility model relates to a forge the instrument field, concretely relates to freely forge and use centre form.
Background
In order to save material, to facilitate processing and to ensure a sufficient life of the mould, a set of moulds should have an inner mould, i.e. a part other than the cross-frame and other functional parts, which is generally embedded in the cross-frame plate. In order to simplify the specification of the large-scale mold, the upper mold cavity is generally directly manufactured on the upper mold template. Some of the requirements for the internal mold design are as follows: has enough strength and rigidity; the alloy has enough hardness and wear resistance and good processability; the process performance is good, the maintenance is convenient, and the precision is enough.
In the traditional forging method, the inner die is designed into two halves, namely, the inner die consists of two core dies with 180 degrees, and the inner die is not easy to demould in the actual production process.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide an easy-to-demould free forging inner die.
In order to achieve the above object, the utility model discloses a following technical scheme realizes:
an inner die for free forging used for processing a blank, comprising: the three core moulds are respectively and closely distributed adjacently to form the inner mould with the circular cross section.
Preferably, the inner die for free forging is configured such that an inner surface of each of the core dies at an included angle formed by each side thereof is chamfered.
Preferably, the inner die for free forging has an inner diameter of a cross section of each of the core dies of 0.35 m to 0.5 m.
Preferably, the inner die for free forging has a cross-sectional outer diameter of 0.4 m to 0.65 m.
Preferably, the inner die for free forging has a wall thickness of 0.05 m to 0.15 m.
The module combines the beneficial effect of present case: the utility model discloses the centre form of the present case of making forms the core that three shape is the same, makes things convenient for the drawing of patterns, and the inner membrance can be made up into to the mandrel of arbitrary three the same specification, and convenient operation, simple structure can solve the problem of being difficult to the drawing of patterns in the actual production process.

Fig. 1 is a schematic cross-sectional view of an inner die for free forging according to an embodiment of the present invention;
fig. 2 is a schematic side view of an inner die for free forging according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
As shown in fig. 1 to 2, the present embodiment provides an inner die 1 for free forging, which is used for machining a blank, including: the three core molds 11 are identical in shape, the cross section of each core mold 11 is in a sector shape with a central angle of 120 degrees, the cross section of each core mold 11 is equal in diameter, and the three core molds 11 are respectively and closely distributed adjacently to form the inner mold 1 with a circular cross section.
The inner mold 1 is formed by combining three core molds 11 with the same shape, so that demolding is facilitated, any three core molds 11 with the same specification can be combined into an inner mold, the operation is convenient, the structure is simple, and the problem that demolding is not easy in the actual production process can be solved.
The inner surface of an included angle formed by each edge of each core mold 11 is in a chamfer shape, so that the product is not damaged, and the demolding is further facilitated.
The inner diameter of the cross section of each core mould 11 is 0.35-0.5 m, and is suitable for common inner membranes.
The outer diameter of the cross section of each core mold 11 is 0.4 m to 0.65 m.
The wall thickness of each core mold 11 is 0.05-0.15 m, the thickness ensures certain hardness and strength, and the processability is good.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
Claims (5)
1. An inner die for free forging, which is used for processing a blank, characterized by comprising: the three core moulds are respectively and closely distributed adjacently to form the inner mould with the circular cross section.
