Embodiment

[0029] The method for processing the wheel cover and the disc of the double-supported blower fan is characterized in that it comprises the following steps:

[0030] 1) Cutting of wheel cover and inlet ring: ① Expand the wheel cover and inlet ring for sample opening; ② Determine the machining allowance; ③ Determine the rebound rate and elongation of the material; ④ Finalize the operability of the designed mold and equipment Cutting size;

[0031] 2) Mold pressing for the wheel cover: ①Design the pressing mold according to the design drawing and the mechanical properties of the material; Whether the data indicators meet the requirements of the design drawings to improve the mold and blanking size and finally improve to pass. The pass standard is that the gap between the molding line and the standard template is ≤1mm. ;

[0032] 3) Turning of the entrance circle: ①Issuing the rough turning process drawing, ②turning the entrance circle on the machine tool according to the proces...

Abstract

A method for machining a wheel cover and a wheel disc of a double bracing blower wheel comprises the steps of wheel disc and inlet ring blanking, wheel cover mold profiling, inlet ring turning, thermal treatment, inspection, wheel disc and shaft disc blanking, shaft disc turning, wheel disc and shaft disc welding, weld root overlap removal, thermal treatment, inspection and the like. According to the method, the quality is reliable, raw materials are saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of fan manufacturing, in particular to a processing method for a wheel cover and a wheel disc of a double-supported blower fan. Background technique [0002] The use of double-supported blowers is becoming more and more common. The existing processing methods of the impeller cover and the disc are: 1. Forging discus; 2. Heat treatment; 3. Inspection; 4. Machining rough turning; 5. Inspection ; 6. Heat treatment; 7. Machining semi-finishing car; 8. Inspection. In this method, the wheel cover is processed from an integral forging, which causes serious waste of materials, and because the rough turning and finishing turning are separately machined, the processing efficiency is low, and the manufacturing cost of the fan is increased. Contents of the invention [0003] Aiming at the defects and deficiencies of the prior art, the present invention provides a method for processing the wheel cover and the disc of the double...
