Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the existing planetary carrier undergoes the step of cleaning the scale during forging, and the shot blasting machine is usually used for shot blasting treatment, but the randomness of the shot blasting machine treatment is relatively large, which is easy to cause The oxide scale treatment of the planet carrier is not thorough, and the treatment effect is poor, so it needs to be improved

Embodiment

[0037] A kind of forging process of planet carrier, refer to figure 1 , including the following steps:

[0038] S01: Basic polishing, put several planetary frames through the shot blasting machine for the first shot blasting treatment to remove most of the oxide skin;

[0039] Shot blasting adopts a rotary table shot blasting machine; the shot blasting time is preferably set at 4 minutes; while ensuring the shot blasting effect, reduce the use of energy.

[0040] S02: High-pressure peeling, cleaning several planetary carriers that have been basically polished through the high-pressure cleaning device along the conveyor belt;

[0041] The transmission belt drives the planet carrier to move in a fixed direction. At this time, a number of high-pressure water guns are used to impact the planet carrier on the conveyor belt in a 360° circle. Removal of the scale attached to the surface of the planetary carrier but has fallen off under the shot blasting action of the shot blasting ...

Abstract

The invention discloses a forging process of a planet carrier, and relates to the processing technology field of the planet carrier. The forging process of the planet carrier aims at solving the technical problems that randomness in processing of a shot blasting machine is large, and unthorough oxide skin treatment of the planet carrier is easily caused. The main point of the technical scheme includes that the basic shot blasting machine is used for polishing, the surface of the planet carrier is washed through high pressure water, oxide skin adhered to the surface of the planet carrier is removed, then secondary sand blasting is performed for fine treatment, and finally high pressure airflow is used for removing chippings; and the treatment effect for the oxide skin is improved.

Description

technical field [0001] The invention relates to the technical field of planet carrier processing, more specifically, it relates to a forging process of a planet carrier. Background technique [0002] The planetary carrier is one of the main components of the planetary gear transmission, and the planetary wheel shaft or bearing is mounted on the planetary carrier; when the planetary wheel is used as a basic component, it is the part that bears the largest external moment in the mechanism. [0003] The existing Chinese patent with the publication number CN105855439A provides a processing method for a planet carrier, including the following steps: S1, selecting a cylindrical steel material with a diameter of 194 mm and a thickness of 52 mm; S2, putting the blank in step 1 into Heating in an intermediate frequency heating furnace; S3, using an air hammer to pull out the hammer on the workpiece obtained in step 2; S4, putting the hammered workpiece into the forming die in the fri...
