Embodiment Construction

[0066] Attached to the following Figure 1-8 This application will be described in further detail.

[0067] The embodiment of the present application discloses a joint blank forging forming process.

[0068] refer to figure 2 , The joint blank forging forming process includes the following steps: S1, blanking; S2, heating; S3, upsetting; S4, joint forming; S5, punching; S6, heat treatment; S7, cleaning shot blasting.

[0069] In S1, round steel is used as the base material, and a sawing machine is used to cut the base material into multiple shorter raw material columns according to the size of the joint blank to be processed.

[0070] In S2, the raw material column is heated by an intermediate frequency heating furnace.

[0071] In S3, the raw material column is forged with a punch to make the diameter of the raw material column thicker and the height shortened to form a raw material blank.

[0072] refer to image 3 , the punching machine includes a workbench 100 and a ...

Abstract

The present application relates to a joint blank forging forming process, belonging to the technical field of forging, which includes the following steps: S1, blanking; S2, heating; S3, upsetting; S4, joint forming; S5, punching; S6, heat treatment; S7, cleaning shot blasting. Since the joint is formed by forging, the internal structure of the joint is more compact, so the strength of the joint is improved, and the mechanical properties of the joint are improved, and because the forging and punching are carried out together, on the one hand, the blank of the joint joint is saved The forming time, on the other hand, saves the forging cost of the enterprise.

Description

technical field [0001] The present application relates to the technical field of forging, and in particular, to a joint blank forging process. Background technique [0002] At present, forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. The mechanical properties of the metal blank can be changed by applying pressure to it to produce plastic deformation. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, while hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. [0003] refer to figure 1 , in the related art, an automobile joint blank is disclosed, including a connecting shaft 500 and a connecting sleeve 600, the connecting shaft 500 is cylindrical, and the connecting shaft 500 is fixedly connected with the connecting sleeve 600. The axis of the...
