Abstract
The invention discloses a mirror roller and its production technology. The mirror roller comprises an outer roller, an inner cylinder, and two shaft sleeves. The production technology of the mirror roller comprises the following steps: preparing materials comprising an No.45 steel seamless steel tube adopted by the outer roller, Q235 adopted by the inner cylinder, and No.45 steel adopted by the shaft sleeves; carrying out rough machining on the excircle of the outer roller, and carrying out boring hole processing on the outer roller; sending the outer roller, the inner cylinder and the shaft sleeves to an electric furnace, heating them to 250DEG C, welding the inner cylinder and the shaft sleeves together, and welding the outer roller and the shaft sleeves together; quenching and tempering the integral body; carrying out semi-fine machining on the outer surfaces of the outer roller and shaft heads; carrying out hole reaming processing on center holes on the shaft sleeves; carrying out high frequency quenching on the cylindrical surface of the outer roller; grinding and polishing the excircle of the outer roller and the shaft heads after cooling; and electroplating hard chromium on the cylindrical surface of the outer roller. By adopting the above mode, the technology disclosed in the invention has the advantages of simplicity and low production cost, and the processed mirror roller has the advantages of high surface hardness, uniform temperature, good calendering effect, compact structure and durable service.
Description
technical field [0001] The invention relates to the field of mirror rollers, in particular to a mirror roller and a production process thereof. Background technique [0002] The mirror roller (oil surface roller) is mainly used for calendering the surface of the object.
