Problems solved by technology

In the traditional single-pass overall rolling forming, the hardening is obvious when the local large deformation is rolled, which is easy to cause local stress concentration, and it is difficult to turn, and it is not easy to process the streamline of the curved surface
When processing the roller, due to the rounded corners at the tip of the tool, the groove of the roller cannot be an ideal sharp-angled shape. Resistance
[0006] In the above work process, the rollers are subjected to high stress and wear quickly. In order to ensure the formi

Abstract

The invention belongs to the technical field of metal plastic forming, and particularly relates to a split roller for rolling forming of a surface microgroove. The split roller comprises a roller spindle, blades, thick baffles and a nut. The roller wheel is made into a split type, so that the tiny hole pattern required by rolling production of the microgroove can be ensured, the problem that the bottom of the groove in the roller is difficult to process is solved, and the sharp corner forming quality of a drag reducing ridge is improved. After blades are prepared in batches, the roller bladesare replaced and combined conveniently, so that the processing and use cost of the roller is reduced, and the machining efficiency is greatly improved in the batch rolling production of the micro-groove.

Description

technical field [0001] The invention belongs to the technical field of metal plastic forming, and in particular relates to a split roller and a method for roll forming micro-grooves on the surface of a plate. Background technique [0002] With the improvement of environmental protection and energy-saving requirements, various drag reduction technologies have attracted people's attention. For example, for civil aircraft, surface frictional resistance accounts for 50% of the total resistance. For example, if the surface resistance of a large aircraft increases by 1%, the consumption of aviation fuel will increase by about 15,000-100,000 barrels per year. Studies have shown that in addition to optimizing the streamlined shape of moving objects, if the skin and wing components are made of bionic drag-reducing materials, fuel consumption can be significantly reduced, the speed of the aircraft can be increased, and the flight range can be extended. The bionic micro-groove drag re...
