Abstract
The invention discloses a novel guide column and guide sleeve structure of a crankshaft forging die. The novel guide column and guide sleeve structure is used for guiding the relative movement between an upper die forging die body and a lower die forging die body of the forging die. The novel guide column and guide sleeve structure comprises three guide column and guide sleeve sets arranged on the parting face between the upper die forging die body and the lower die forging die body. Each guide column and guide sleeve set comprises a guide sleeve only fixed to and positioned on the upper die forging die body or the lower die forging die body, and a guide column which is only fixed to and positioned on the lower die forging die body or the upper die forging die body, corresponding to the guide sleeve on the upper die forging die body or the lower die forging die body and is positioned in the guide sleeve in a slidable and penetrating manner. The three guide column and guide sleeve sets include the two guide column and guide sleeve sets at the two ends of one side of the parting face, and the guide column and guide sleeve set on the other side of the parting face, wherein only one end of the guide column and guide sleeve on the other side of the parting face is positioned. The distribution direction of the guide columns and the guide sleeves, on the upper die forging die body and the lower die forging die body, of the corresponding two guide column and guide sleeve sets is opposite to the distribution direction of the guide column and the guide sleeve, on the upper die forging die body and the lower die forging die body, of the other guide column and guide sleeve set. The novel guide column and guide sleeve structure is simple in structure, beneficial to die arrangement, die replacement and adjustment, convenient and rapid to operate and use, capable of effectively solving the problem that the forging piece offset amount is difficult to control, high in forging process stability and good in product consistency.
Description
Technical field
The invention belongs to technical field of forging, be specifically related to a kind of novel guide pillar guide sleeve structure of Crank Forging Die.
Background technology
Bent axle is the critical component inside engine, mostly adopts forging molding, and its typical technological process is: blanking-eddy-current heating-base, blocking, finish-forging-trimming-correction-heat treatment-ball blast-flaw detection-surface treatment-packaging-warehouse-in.Wherein, finish-forging operation is the shaping important procedure of forging, and the shape of bent axle and precision thereof depend on the effect of finish forging to a great extent.
In actual production, because crankshaft forging is complicated, the reasons such as production equipment rigidity and guiding are difficult to absolute guarantee, and mould is die-filling, cause finish-forging part existence offsetting to a certain degree, affect forging quality.General forging die only has equipment guide pillar guide pin bushing or Die lock catch to play the guiding role, and forging exists larger offsetting, and Forging Technology is unstable, therefore, easily produces following technical barrier and quality problems when crankshaft forging is shaping:
1, forging offsetting amount is comparatively large, and forging shape, size and precision thereof are difficult to ensure;
The operating spaces such as 2, forger, manipulator or step rate are little, the transfer of inconvenient forging between each station;
3, Forging Technology poor stability, the fluctuation of forging shape and size is large;
4, die-filling operation and location inconvenience, the die-filling time and the die debugging time long, percent defective is higher.
