Automobile covering part five-axis rolling edge covering profile modeling programming method and device

Abstract

The invention provides an automobile covering part five-axis rolling edge covering profile modeling programming method and device. The automobile covering part five-axis rolling edge covering profilemodeling programming method comprises the following steps of: driving a profile modeling machine to move through external force according to the action requirements of a practical machining technologyto form a movement locus, instructing a servo system to read a plurality of coordinate parameters of each axis on the movement locus, which are output by a coder, thus generating a working procedurewhich is consistent with the movement of an actual production process, and then extracting and importing the procedure into production equipment. The automobile covering part five-axis rolling edge covering profile modeling programming method and device overcome the shortcomings of the prior art, can perform automobile covering part five-axis rolling edge covering effectively and reliably, substantially improves the programming efficiency, and are good for the popularization and application of the advanced rolling edge covering technology of automobile covering parts.

Description

technical field [0001] The invention relates to the technical field of mechanical parts processing, in particular to a five-axis rolling edge wrapping profiling programming method and a device for an automobile cover part. Background technique [0002] Because the rolling process has the advantages of high efficiency and can reduce a large number of molds, it has become the development direction of the hemming processing of automobile panels. Since the rolling and hemming of automobile panels is a complex process of multi-curved surface forming, the principle is to use rolling The space movement track of the working busbar of the head squeezes the workpiece to realize the wrapping. Due to the characteristics of the process, there is no mature technology for machine programming directly based on the design drawings. Although it is possible to use the existing general-purpose five-axis numerical control system or robot teaching system to manually program the rolling of automot...

Problems solved by technology

Due to the characteristics of the process, there is no mature technology for machine programming directly based on the design drawings. Although it is possible to use the existing general-purpose five-axis numerical control system or robot teaching system to manually program the rolling of automotive panels, the rolling track is very complicated. , manual programming is too dependent on the degree of personnel's mastery of the hemming process and equipment, the workload is large, time-consuming, and repeated processing verification and modification are required. The initial program changes are large and cannot meet the actual production needs, which restricts rolling hemming Promotion and application of new technology
