Full-automatic polishing tool for environmental ultrahard coating corrugator roll

Abstract

The invention relates to a full-automatic polishing tool for an environmental environmental ultrahard coating corrugator roll, comprising a manipulate platform, an air draft dust collector and a control device, wherein the manipulate platform is provided with an index chuck for clamping and regulating angles of a corrugator roll to be processed, a tail seat tip, a flexible polishing wheel for polishing the corrugator roll to be processed, a horizontal drive device for driving the flexible polishing wheel to horizontally move, a vertical drive device for driving the flexible polishing wheel to vertically move and a power-driven device for driving the flexible polishing wheel to rotate. The core of the invention is as follows: the special flexible polishing wheel and a high-speed rotating motor automatic drive device are adopted so that the flexible polishing wheel can be pressed on the flute teeth of the corrugator roll under the high speed rotation for coping and shaping while grinding effect on the coating does not generated, and the surface roughness of the coating corrugator roll can be processed from Ra3.0-4.0 microns in a spraying state to Ra 0.8-1.6 microns, thereby reaching the use environments.

Description

technical field [0001] The invention relates to a fully automatic environment-friendly corrugated roller polishing machine tool, which is mainly used for surface processing of corrugated rollers with superhard coatings. Background technique [0002] The surface of the uncoated corrugated roll is generally ground with a corrugated roll, and the diamond dresser corrects the white corundum and silicon carbide grinding wheels to ensure the design parameters and surface roughness of each corrugated tooth profile. For corrugated rollers with superhard coatings (such as tungsten carbide coatings), since the coatings are harder than white corundum and silicon carbide grinding wheels, only diamond grinding wheels can be used for grinding, but there is no harder dresser for diamond grinding. Grinding wheel is used for dressing, so the surface of corrugated roller with superhard coating cannot be processed by traditional special corrugated roller grinder. Although it has been reported...

Problems solved by technology

For corrugated rollers with superhard coatings (such as tungsten carbide coatings), since the coatings are harder than white corundum and silicon carbide grinding wheels, only diamond grinding wheels can be used for grinding, but there is no harder dresser for diamond grinding. The grinding wheel is dressed, so the surface of corrugated rollers with superhard coating cannot be processed by traditional special corrugated roller grinders

Although it has been reported that profiling electrochemical melting or electric spark ablation is used to process such corrugated rolls, due to the variety of corrugated roll tooth types (including A, B, C, E, F, BC, AC, U, V, etc. Ten types), the tooth profile parameters have high accuracy, the profiling electrode cannot be completely consistent with the tooth profile, and the coating thickness of the super-hard coated corrugated roller is only 0.06-0.08mm, and the partial coating will be removed if there is a slight error In addition, superhard coatings such as tungsten carbide will also affect the bonding strength between the coating and the corrugated roll due to electrochemical corrosion during electrochemical melting or spark ablation.
