Abstract

The invention discloses a production method and a production system for a bevel gear, and belongs to the technical field of bevel gear production. The method comprises the following steps that (1), amaterial section conforming to requirements is prepared; (2), the material section is heated to 1150-1180 DEG C in a heating device; (3), the heated material section is rolled into a material cake ona blank making and swinging rolling device; (4), the middle of the material cake is rolled to form a center taper groove and is rolled to reach the preset thickness through the blank making and swinging rolling device; (5), a through hole is punched in the center taper groove through a punching device; (6), a ring expanding device is used for carrying out ring expanding to obtain an annular blank;(7), rolling and forming are carried out on the annular blank through a forming and winging rolling device to obtain a product blank; and (8), the product blank undergoes heat treatment and surface treatment to obtain a finished product. Through the method, the product with higher precision, the lighter weight, the better product quality and the smaller turning allowance can be obtained, and thecost is saved.

Description

technical field

[0001] The invention belongs to the field of bevel gear production, in particular to a bevel gear production method and production system. Background technique

[0002] Bevel gears are widely used in automobiles, engineering machinery and other fields. The traditional processing method uses a dedicated milling machine to process the tooth shape, which has low efficiency and low material utilization, resulting in high processing costs for bevel gears, and the processing accuracy of bevel gears is difficult to meet the needs of power transmission. Different batches The quality stability among the products is poor. In theory, forging can be used to prepare bevel gears (blanks), and there are some brief introductions in related academic research.

[0003] For example, the patent application number CN201110147643.5 discloses a manufacturing method for precision forging of spiral bevel gears, which includes the following steps:

[0004] (1) Prepare the raw mater...
