Abstract

The utility model relates to a hexagonal flange stamping die comprising an upper die and a lower die which matches the upper die, and being characterized in that the upper die comprises an upper die body, a die shank and a discharge arm, the die shank is fixed through screws on the upper die body of which the outer wall is provided with a protecting jacket, and which is provided from bottom to top with a hexagonal die hole, the T-discharge arm is inserted into the discharge hole in the die shank and the upper die body, the lower die comprises a lower die body and a lower die back-up which is fixed together with the lower die body through screws, and the lower die body is provided with a round die hole from top to bottom. The utility model has the advantages that the processing of the hexagonal flank is simple in procedure, timesaving, laborsaving, and high efficiency, the stamping die is simple in structure, convenient in operation, and material saving.

Description

Hexagonal flange stamping die

Technical field

The utility model relates to a kind of machining tool of hexagonal flange, exactly is a kind of hexagonal flange stamping die.

Technical background

Processing instrument thermocouple is at first to cut one section stainless steel roundwood that leaves allowance that needs length with taking over the hexagonal flange at present, is processed into the hexagonal flange by lathe, milling machine again.The manufacturing procedure complexity, time-consuming, take a lot of work, the low and waste raw material of efficient.

The utility model content

The utility model purpose is at existing defective, provides a kind of manufacturing procedure simple to people, saves time, the saving of labor hexagonal flange stamping die that efficient is high.

The utility model comprises patrix and the counterdie that mates with patrix, it is characterized in that:

A, patrix comprise upper die body, die shank and discharge arm, and die shank is fixed on upper die body by screw, and the upper die body outer wall has a protective sleeve, the bottom-up hexagonal nib that has of upper die body, and T-shaped discharge arm inserts in the dumping pit that has on die shank, the upper die body;

B, counterdie comprise lower mold body and are fixed in the counterdie backing plate of one with it by screw, from up to down have a circle nib on the lower mold body.

The effect of utility model

Not only manufacturing procedure is simple for the utility model processing hexagonal flange, and save time, the saving of labor, the efficient height.Simultaneously simple in structure, easy to operate, economize in raw materials.
