Abstract

The invention discloses an automobile arbor bar material efficient and environment-friendly rolling process. The automobile arbor bar material efficient and environment-friendly rolling process comprises the following steps that S1, a steel blank is selected; S2, the steel blank is put into a conveyor and is fed into a heating furnace to be heated through the conveyor; S3, a furnace outlet rollerpassage conveys the steel blank after heating treatment to a rough rolling machine set; S4, a material after rough rolling is conveyed to a cold scattering roller passage; S5, the cold scattering roller passage conveys the cooled material to a finish rolling vertical roller machine set to be subjected to finish rolling; S6, specified-length shearing is performed on the material by a shearing machine arranged at the material output end of the finish rolling vertical roller machine set; and S7, check and accept are performed on the arbor bar material. The automobile arbor bar material efficientand environment-friendly rolling process is free of pollution, environment friendly, efficient in rolling and suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a high-efficiency green rolling process for mandrels for automobiles. Background technique [0002] The mandrel is used to support the rotating parts and only bears the bending moment without transmitting the torque. Some mandrels rotate, such as the axles of railway vehicles, and some mandrels do not rotate, such as the shafts supporting pulleys. According to whether the shaft rotates when it is working, the mandrel can be divided into a rotating mandrel and a fixed mandrel. [0003] In order to ensure the safety and service life of the car, the quality of the mandrel must be guaranteed. In the prior art, the mandrel for automobiles is cumbersome to process, the quality cannot be guaranteed, and it is not environmentally friendly. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a high-effi...
