Chemical bluing pretreatment device

Abstract

The invention relates to the field of chemical engineering, in particular to a chemical bluing pretreatment device. The technical problem to be solved by the invention is to provide the chemical bluing pretreatment device. According to the technical scheme, the chemical bluing pretreatment device comprises a lathe bed plate, a work control screen, a tool storage box, a mechanical cleaning mechanism and the like; and the middle left portion of the top end of the lathe bed plate is connected with a workpiece fixing bluing auxiliary mechanism, and the middle portion of the right end of the workpiece fixing bluing auxiliary mechanism is connected with a limiting pulling mechanism. According to the chemical bluing pretreatment device, dust on the surface of a spring steel sheet is removed whilethe bending state of the spring steel sheet is maintained; and under the condition that the original curly shape and elasticity of the spring steel sheet which is bent into a coil are not changed, the inner surface and the outer surface of the spring steel sheet are subjected to continuous synchronous rust removal treatment, and the spring steel sheet is subjected to oxidation bluing under the condition of high-frequency vibration after rust removal is completed.

Description

Technical field [0001] The invention relates to the field of chemical industry, and in particular to a chemical bluing pretreatment device. Background technique [0002] A process in which steel or steel parts are heated to an appropriate temperature in air, water vapor or chemicals to form a blue or black oxide film on the surface. Also called blackening. The oxide film formed on the surface of black metal after "blueing" treatment, the outer layer is mainly ferric oxide, and the inner layer is ferrous oxide. [0003] In the existing technology, some old spring steel sheets need to be blued for surface protection. However, since the spring steel sheets are rolled as a whole, and there are varying degrees of rust impurities on both the inner and outer surfaces of the spring steel sheets, when surface treatment is performed manually, Manpower cannot be accurately controlled, which leads to irreversible deformation of the spring steel sheets during manual rust removal, resul...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fact that the spring steel sheet is coiled as a whole, and there are different degrees of rust impurities on the inner and outer surfaces of the spring steel sheet, when the surface treatment is performed manually, the manpower cannot be accurately controlled, which in turn causes the spring steel to be damaged by manpower during the manual rust removal treatment. The irreversible deformation of the sheet leads to a decrease in the elastic properties of the spring steel sheet. At the same time, the manual surface treatment process of the spring steel sheet requires the cooperation of multiple people to carry out the collection and derusting operation. The manual efficiency is low, and the bluing During the process, the spring steel sheet cannot be guaranteed to vibrate evenly, resulting in uneven bluing on the surface of the spring steel sheet. The technical problem to be solved is: to provide a chemical bluing pretreatment device
