Problems solved by technology

[0002] Most precision forgings are poured by upper and lower dies. Precision forgings may be dislocated during the forging process of upper and lower dies and affect product quality. It is necessary to reduce the error caused by the dislocation of upper and lower dies of precision forgings in order to control product quality in time, and most of the existing precision forgings Forgings will be limited by the closed height of the mold during forging, so it is impossible to achieve smooth demolding of forgings, and it is impossible to forge precision forgings, such as journals, hubs, etc. Production

Abstract

The invention discloses a precision forging die structure facilitating forging. The precision forging die structure comprises a lower die, a die cavity is formed in the center of the lower die, a lower die core plate used in cooperation with the die cavity is arranged in the die cavity, a lifting rod is arranged on the bottom face of the lower die core plate, the other end of the lifting rod is connected with a power device, two round grooves are connected through a linear groove, threaded rods are inserted into two threaded through holes, and driven gears used in cooperation are arranged on two driving gears. The precision forging die structure is simple, linkage of the lower die core plate, the lifting rod and the power device is achieved, and use is flexible and convenient; and by meansof the arrangement of the above structure, assembly is facilitated, the assembly time is shortened, the product quality is better improved, the production efficiency is greatly improved, meanwhile, the production cost is reduced, and the die capacity is effectively enlarged.

Description

technical field [0001] The invention relates to the technical field of die structures for precision forgings, in particular to a die structure for precision forgings that is convenient for forging. Background technique [0002] Most precision forgings are poured by upper and lower dies. Precision forgings may be dislocated during the forging process of upper and lower dies and affect product quality. It is necessary to reduce the error caused by the dislocation of upper and lower dies of precision forgings in order to control product quality in time, and most of the existing precision forgings Forgings will be limited by the closed height of the mold during forging, so it is impossible to achieve smooth demolding of forgings, and it is impossible to forge precision forgings, such as journals, hubs, etc. Production. For this reason, need a kind of convenient forging precision forging die structure. Contents of the invention [0003] The object of the present invention is ...
