Abstract

The invention provides a blank positioning structure for a plate forged piece. A forging eccentricity phenomenon caused by inaccurate blank positioning during the forging of the conventional plate forged piece can be avoided, so that the production efficiency can be improved, and the quality of the forged piece can be ensured. The blank positioning structure comprises a blank and a forging die, and is characterized in that a lower die of the forging die is provided with a positioning female end; a corresponding positioning male end is arranged on one side, which contacts with the lower die, of the blank; and the positioning female end and the positioning male end form a matched connection structure of a lug boss and a groove.

Description

The blank location structure of dish forging

Technical field

The present invention relates to the die forging technical field, especially relate to the die forging technical field of coiling forging, be specially the blank location structure of dish forging.

Background technology

At present, when forging for the dish forging, the location of blank often will rely on execute-in-place worker's range estimation to position, this localization method not only needs the long period to go blank centering, and the forging positioning accuracy is lower, often occur forging eccentric phenomenon, also can waste more raw material in the following process, even cause product defective.

Summary of the invention

For the problems referred to above, the invention provides the blank location structure of dish forging, the forging eccentric phenomena that causes owing to blank location inaccuracy when it can solve existing dish forging forging, thus can enhance productivity, guarantee forging quality.

Its technical scheme is such, it comprises blank and forging die, it is characterized in that: the counterdie of described forging die is provided with the female end in location, described blank is provided with corresponding location hero end with a side of described counterdie contact, is the structure that is connected of boss and groove between the male end in the female end in described location and location.

It is further characterized in that:

The female end in described location is positioning boss, and the male end in described location is detent;

The female end in described location is detent, and the male end in described location is positioning boss.

Its further feature also is:

The female end in described location, the male end in location be shaped as any one shape in circular, square or the triangle.

Adopt the blank location structure of dish forging of the present invention, its beneficial effect is: the male end in location on its male end in location by forging counterdie centre slice and the blank cooperates the location fast, accurately, thereby locating speed and the positioning accuracy of energy Effective Raise blank, avoid forging the generation of eccentric phenomena, save raw material, and greatly improved production efficiency.
