Embodiment Construction

[0026] The following examples refer to Figure 1~5 .

[0027] 1. Use a three-coordinate measuring machine to measure five groups of rolled blade samples 1 of the same batch, and measure several groups of cross-sections for each rolled blade sample 1. Four detection points 2 are obtained at 2-3 mm from the front and rear edges.

[0028] 2. Measurement data processing: According to the measured five groups of rolled blade samples 1, the average value of the detection points on the same section is calculated, and the average value is used as the final detection point of the rolled blade sample. The specific calculation method is as follows :

[0029] p i ( x ‾ i , y ‾ i , z ‾ i ...

Abstract

The invention discloses a rolled blade flange head smooth transferring machining method which is used for solving the technical problem that an existing rolled blade flange head machining method is low in efficiency. According to the technical scheme, the rolled blade flange head smooth transferring machining method includes the steps of firstly, measuring a rolled blade sample piece and obtaining a plurality of detection points, building a rolled blade front flange and rear flange molded surface CAD model through a rolled blade CAD model, conducting horizontally moving and matching on the front flange and rear flange molded surface CAD model according to the detection points of the rolled blade sample piece, generating a numerically controlled machining auxiliary line according to the front flange and rear flange molded surface CAD model which is horizontally moved and matched, and finally, achieving smooth transferring of a front rolled blade flange, a rear rolled blade flange and a blade body by adopting four-coordinate numerically controlled machining. The singleton rolled blade flange head machining time in the prior art is reduced from more than 2 hours to within 12 minutes, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a method for processing the edge head of a rolling blade, in particular to a method for processing the edge head of a rolling blade with smooth transfer. Background technique [0002] For the treatment of the front and rear edges of rolling blades, compared with developed countries, there is still a large gap in the processing methods, efficiency and precision of rolling blades in my country. Industrial developed countries generally use CNC machining centers and CNC grinding machines to process rolling blades, which greatly improves the overall processing efficiency, surface geometric accuracy and surface quality of rolling blades. However, these related process equipment involve national security and market competition needs. Its core technology is not disclosed. [0003] For the processing of the front and rear edges of the rolled blades, the traditional processing method adopted in my country is to firstly remove a large am...
