Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0058] refer to figure 2 , which is a forging forming process of a joint blank disclosed by the present invention, comprising the following steps:

[0059] Step 1, blanking, using round steel as the base material, and cutting the raw material column according to the size of the joint blank to be processed;

[0060] Step 2, heating, heating the raw material column;

[0061] Step 3, upsetting, the raw material column is forged, so that the diameter of the raw material column becomes thicker and the length becomes shorter;

[0062] Step 4, forming the connecting shaft,

[0063] 1. Set an inverted tapered cavity 221 whose bottom surface is the same diameter as the connecting shaft;

[0064] 2. Reheat the upsetting raw material column and place it in the inverted conical cavity-221, and continue to forge the raw material column with a punch until the raw mate...

Abstract

The invention relates to a forging forming technology of a joint blank. The forging forming technology comprises the steps of (1) blanking, (2) heating, (3) upsetting, (4) connecting shaft forming, (5) connecting ring forming, (6) heat treatment and (7) cleaning and shot blasting. The technology has the effects of improving the strength and quality of the joint blank.

Description

technical field [0001] The invention relates to the technical field of forging processing, in particular to a forging forming process of joint blanks. Background technique [0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. The mechanical properties can be changed by applying pressure to the metal blank to cause 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, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank. [0003] As shown in the figure, an existing joint blank 3 for automobiles includes a connecting shaft 31 and a connecting ring 32 affixed to one end of the connecting shaft 31. The axis of the connecting ring 32 is perpendicular to the axis of the connecting shaft 31, and the connecting shaft 31 is cylin...
