Symmetric outer planetary wheel combined precision forging die

Abstract

The invention relates to dies, in particular to a symmetric outer planetary wheel combined precision forging die. The symmetric outer planetary wheel combined precision forging die comprises an outerdie body, a lower preliminary die, a lower final die, a lower die bottom plate, a guide rail plate, a rack plate, measuring rods, a movable plate, an action mechanism, a gear, a rack jacking rod and ahand pulling plate. The symmetric outer planetary wheel combined precision forging die is characterized in that a groove is formed in the upper die, the position between the upper die and the lower preliminary die and the position between the upper die and the lower final die are guided and limited through the measuring rods, the lower preliminary die and the lower final die are fixed to the lower die bottom plate, the lower die bottom plate is engaged with the guide rail plate, and one end of the lower die bottom plate is fixed to the action mechanism. The rack plate is embedded in the guiderail plate in a falling manner and engaged with the gear. The gear is engaged with the rack jacking rod. The hand pulling plate is fixed to the rack plate and the guide rail plate. After the technical scheme is adopted, the forging precision is high, the quality is good, machining is omitted, and time, labor and materials are saved; and efficiency is high, the problem about trimmings is solved, and the service life of the die is prolonged.

Description

technical field [0001] The invention relates to the technical field of forging dies, in particular to a symmetrical outer planetary wheel combined precision forging die. Background technique [0002] At present, the outer planetary wheel has been widely used in the transmission mechanism. During the use of the traditional outer planetary wheel forging die, flashes will be generated on the forged parts; there are often quality defects, and the blanks of the processed parts need complex mechanical cutting Processing, the workload increases, there is a lot of cutting allowance, the waste of materials is large, the cost is increased, and the production efficiency is not high; in addition, the forging pressure will inevitably have a strong stress impact on the mold, and the mold will deform under the action of strong stress , It affects the structure and precision of the mold and also affects the service life of the mold, which brings certain economic losses to the user.
