Embodiment Construction

[0007] 1. Due to the stamping deformation of the inner hole after stamping, the cold punching oil tank process is arranged after the rough turning gear end face, and before the finish turning gear inner hole and end face. After the rough turning of the gear end face, the oil groove on the gear end face is directly punched out with a mold, and then the inner hole and end face of the gear are finished, that is, the cold punching process of the oil groove on the gear end face is completed, and then enters the next process of broaching the inner hole.

[0008] 2. Design principle of oil groove on gear end face:

[0009] a. The depth of the oil groove on the end face of the gear is 1±0.2, and the depth of the oil groove on the end face of the cold stamping gear is 1.7±0.1 (including the margin of 0.6 on the end face of the finishing car and 0.1 of the margin on the grinding end face);

[0010] b. Obtained from experience: the oil grooves on the gear end surface below φ50 are symmet...

Abstract

The invention relates to a cold punching processing method for a gear-face oil groove. The processing procedure of the cold punching processing method for the gear-face oil groove comprises the following steps: a rough turning gear face, a fine turning of a gear inner hole and the gear face, wherein after the rough turning of the gear face, the gear-face oil groove is directly punched coldly by a die, and the gear inner hole and the gear face are finely turned, namely cold punching processing of the gear-face oil groove is completed. By adoption of the processing method to process the gear-face oil groove, the frock processing labor hour and the cutting-tool wear can be reduced. Moreover, as for an AQ015 five-gear driving gear inner concave station oil groove which can not be processed by the milling technology, the problem that the oil groove is difficult to process can be completely solved by the cold punching technology. The cold punching processing method for the gear-face oil groove not only guarantees the quality but also improves the efficiency.

Description

Technical field [0001] The invention relates to a processing method for an oil groove on a gear end face, in particular to a cold stamping processing method for an oil groove on a gear end face. Background technique [0002] The oil groove on the gear end face is a common lubricating structure in mechanical transmission devices, and it is usually realized by milling or forging in process processing. The production efficiency of milling oil groove is low. With the increase of production demand and cost control, it is difficult to meet the requirements of high-efficiency and mass production. However, it is difficult to ensure the depth and width of the forged oil groove during machining, which causes certain processing difficulty in machining, and the tool wears seriously during rough turning. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a method for cold punching the oil groove on the end surface of the gea...
