Description
Technical field
The utility model relates to a kind of hard alloy screw plate with external structure.
Background technique
Hard alloy is the widely used mold materials in metal material forging molding field.Sintered-carbide die is not only wanted
Meet the forging high intensity of processing request, antiwear characteristic, also to have a reasonable mould structure design, satisfaction is easily installed, the longevity
The actual operation requirements such as life length.In view of than this patent provides a kind of hard alloy screw plate with external structure.
Summary of the invention
The utility model provides a kind of hard alloy screw plate with external structure, and structure is simple, at low cost, and function is suitable
With.
The technical solution of the utility model is：A kind of hard alloy screw plate with external structure includes ontology, center
Through-hole and external structure, the ontology shape are cylindrical structure, and the central through hole is set to body interior, and runs through ontology
Upper and lower surface, the external structure are set on the outside of the end of ontology, and the external structure is outwardly extending ledge arrangement, institute
The bottom surface for stating ledge arrangement is concordant with ontology end face, and the radial thickness of the ledge arrangement is less than the radius of ontology, the lug
The height of structure is less than a quarter of body height, and the bottom edge of the lug is provided with chamfering.
Further preferential, the end of the central through hole is provided with chamfering.
Further preferential, the central through hole includes the unequal two sections of diameter.
It is further preferential, chamfering is provided on the outside of the end of the ontology.
Compared with prior art, the utility model has the advantages that：Not only to meet the height of forging processing request
Intensity, antiwear characteristic will also have reasonable mould structure design, the actual operation requirements such as satisfaction is easily installed, the service life is long.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
