Abstract

A short clamping semi-closed adjustable upsetting die comprises a female die upper die, a female die lower die, a rear positioning insert, an adjusting bolt, a locking nut, an adjusting gasket and a positioning bolt. An insert positioning clamping groove is formed in the female die lower die, a positioning boss is arranged on the rear positioning insert, and the insert positioning clamping groove and the positioning boss are clamped and matched; the rear positioning insert and the female die lower die are fixed through the positioning bolt; an adjusting bolt penetrating hole is formed in the middle of the rear positioning insert, a screw rod of the adjusting bolt penetrates through the adjusting bolt penetrating hole in the middle of the rear positioning insert and extends to the other side of the rear positioning insert, and the locking nut is connected to the screw rod of the adjusting bolt in a screwed mode; the adjusting gasket is positioned between a nut of the adjusting bolt and the rear positioning insert; and plier operation space is arranged at the position, right facing the top of the rear positioning insert, in the female die upper die. According to the upsetting die, upsetting blank making of a large-sectional-area-difference short clamping forge piece can be met, material feeding and return can be adjusted, the stability of the upsetting forming quality of the short clamping forge piece can be guaranteed, and the safety during upsetting blank making can also be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of upsetting billet, in particular to an adjustable upsetting die with short clamping semi-closed type. Background technique [0002] At present, when carrying out upsetting forging blanks with short clamping forgings, the existing technology still has the following drawbacks: [0003] First of all, when the upsetting die adopts a closed structure, the upsetting die is not suitable for the billet whose center of gravity is located in the forming part. When the pliers are removed, the billet will fall under the action of gravity, and it will be positioned after being fixed, so it cannot be adjusted Advance and return materials. [0004] Secondly, when using the pincer positioning method, although the problem of billet slipping can be solved, because the advance and retreat of the material cannot be adjusted, it cannot be flexibly applied to production when the billet specification is unstable. [0005] Thir...
