Abstract

The invention relates to a rotary worktable for forging pie-shaped forging pieces, relating to a forging tool and solving the problems of the prior art, such as unreasonable rotary positioning, great friction resistance, great labor intensity, and the like. The rotary worktable for forging pie-shaped forging pieces is characterized in that a guide sleeve is arranged in the vertical direction between a turntable and a base, a positioning round key connected with the movable worktable is mounted on the base, the turntable is supported by a turntable bearing which is supported by a belleville spring pack, a bracket is mounted at one side of the base, and a driving mechanism comprising a hydraulic motor, a coupler, a shaft, a pinion and a bull gear is mounted on the bracket. The invention avoids the adverse influence of unbalance loading caused in process of putting a forging piece in or separating the forging piece from the worktable, has favorable buffer effect, greatly prolongs the service life of spare parts and improves the working efficiency.

Description

technical field

[0001] The invention relates to forging equipment, in particular to a forging tool. Background technique

[0002] The forging rotary table is a special tool for forging press forging pie-shaped forgings. The uniform rolling of the pie-shaped forgings is realized through the uniform rotation of the rotary table, thereby effectively improving the shape of the pie (rings, flanges, tubes, etc. ) quality of forgings.

[0003] figure 1 It is a schematic diagram of the structure of the existing rotary table for forging cake-shaped forgings. There is following shortcoming in prior art:

[0004] 1. The turntable 2 and the base 3 of the rotary table are directly positioned, and "steel-steel" friction occurs between the turntable 2 and the base 3 when turning, the effect is not good, and it cannot be repaired after severe wear.

[0005] 2. The rotary motion of the turntable 2 of the rotary table is driven by manual, pneumatic or hydraulic cylinders. The rotation sp...
