Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0031] Such as Figure 1-Figure 7 As shown, the vertical forging and rough-finishing process of an active spiral bevel gear with a boss provided in this embodiment, the active spiral bevel gear is used for the rear axle of an automobile, and the vertical forging and rough-finishing process includes the following steps:

[0032] Step 1——Blanking: Select a round billet that meets the specifications according to the consumption quota. In this embodiment, a round billet with a diameter of 60mm is selected, such as figure 2 As shown, the round billet is heated to the initial forging temperature by using a 350KW medium frequency induction heating furnace;

[0033] Step 2 - Billet making: After the round billet is heated to the initial forging temperature, use a 560Kg air hammer to elongate one end of th...

Abstract

The invention discloses a vertical forging and rough and finish turning process for a driving spiral bevel gear with a boss, and belongs to the field of automobile driving bevel gear machining processes. The vertical forging and rough and finish turning process for the driving spiral bevel gear with the boss comprises the steps that 1, blanking is conducted; 2, a blank is prepared; 3, vertical forging is conducted, specifically, the blank is placed in a finish forging die cavity, and then flash is cut off through a closed single-point press; and after forging, rough turning and finish turning are conducted on a forged piece, and the driving spiral bevel gear is obtained. According to the vertical forging and rough and finish turning process for the driving spiral bevel gear with the boss, the vertical forging process scheme is adopted for forging the driving spiral bevel gear forge piece with the boss, the boss and a rod portion are free of parting surfaces, the problems of metal backflow folding at the position of the boss and thread rolling deformation of the rod portion are solved, and meanwhile the material utilization rate can be increased.

Description

technical field [0001] The invention relates to the field of automobile active bevel gear processing technology, in particular to a process of vertical forging and rough turning of an active spiral bevel gear with a boss. Background technique [0002] Spiral bevel gear is a kind of transmission part that can transmit smoothly and with low noise according to a stable transmission ratio. Among various mechanical transmissions, the transmission efficiency of the spiral bevel gear is the highest, so it has great economic benefits for various transmissions, especially high-power transmissions; the transmission pair of transmission parts required to transmit the same torque saves the most space, compared with belts and chains. The space required for the transmission is small; the transmission ratio of the spiral bevel gear is permanently stable, and a stable transmission ratio is often the basic requirement for transmission performance in the transmission of various mechanical equ...
