Abstract

The invention discloses a forging forming technology of a V-shaped-cavity forged piece, and relates to the technical field of forged piece forging. The forging forming technology includes the steps that firstly, a blank is pre-forged into a hexagonal blank with the certain specification; then, the hexagonal blank is cut into two parts and discharged to form pre-forged blanks; finally, the pre-forged blanks are put into a die, extruded and formed. Forming is carried out with the pre-forged blanks and the die forging method, the blank is pre-forged into the hexagonal forged piece through free forging, and then the hexagonal forged piece is cut into the two parts, the two parts are reversely extruded and formed in the die, the metal flow direction of the product is improved, the better fine texture and the better mechanical performance of a material are obtained, and the strength value can be improved by 10%; die forging forming is adopted, the using rate of the material is increased, the deformation amount of the forged piece is increased, the mechanical performance of the product is improved, the whole forging process is high in speed, the processing cycle is shortened, the processing cost is reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of forging forging, in particular to a forging forming process of a V-cavity forging. Background technique [0002] The V-shaped cavity bracket connector is an important connector in a certain project. The product shape is a V-shaped cavity structure, which can withstand variable and lifting loads, change the direction of torque transmission, and can quickly lift and eject equipment. The conventional forging process is free forging. The billet is forged into a module. The heat treatment section is thick, resulting in low mechanical properties after quenching + tempering. The cavity is processed by machining, the material utilization rate is low, and the processing cycle is long and the cost is low. high. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention aims to provide a forging forming process of a V-cavity forging. [0004] In order to...
