A rapid prototyping device and method for abrasives with regular arrangement of abrasives

Abstract

The invention provides a device for rapidly molding a grinding tool with a regularly arranged abrasive material. The device comprises a horizontal rotating worktable, a step motor, a light curing optical path system, a grinding tool carrier and a feeding mechanism. A method for rapidly molding the grinding tool with the regularly arranged abrasive material comprises the following specific steps that the grinding tool carrier is mounted and fixed on the worktable, a heating device is turned on to preheat the grinding tool carrier, the step motor drives the worktable to rotate, a powdery material for molding in a stock bin is spread on the grinding tool carrier by use of a vibrating screen, a powdery material layer on the grinding tool carrier is evenly and flatly scraped according to the thickness of a molded layer by use of a scraper blade, the light curing optical path system scans the powdery material for molding on the grinding tool carrier according to a set program and thus cures the powdery material layer. The device and the method have the advantages of simple operation, convenience in use, improved production efficiency, achieved regular arrangement of the abrasive material in the grinding tool, short grinding tool molding cycle, stable molding process, guaranteed molding quality stability and reduced grinding tool preparation cost.

Description

technical field [0001] The invention belongs to the technical field of abrasive tool production, and in particular relates to a rapid prototyping device and method for abrasive tools with regularly arranged abrasive materials. Background technique [0002] In the field of mechanical processing, grinding is generally used for parts with high surface quality requirements, and abrasive tools (grinding wheels, grinding discs, saw blades, etc.) The internal structure and preparation process of the abrasive layer for machining have an important impact on the surface quality of the workpiece and the performance of the abrasive tool. The abrasive layer of abrasive tools is usually composed of abrasives, binders, fillers, etc. The traditional preparation process generally adopts mixing and then molding through a press, high-temperature sintering furnace or other molding equipment, and most of the operating procedures are done manually. Due to the small size and irregular shape of th...

AI Technical Summary

Problems solved by technology

[0004] (1) The position of the abrasive is random, and the random distribution of the abrasive in the traditional abrasive tool preparation process makes the performance of the abrasive tool have many unstable factors, resulting in problems such as poor stability of workpiece grinding quality, low controllability of the service performance and life of the abrasive tool ;

[0005] (2) The preparation process of abrasive tools is complicated, and due to many unstable factors, the product quality is difficult to guarantee;

[0006] (3) The preparation cycle of abrasive tools is long, and it is difficult to meet the needs of customers under the current changing market conditions;

[0007] (4) The preparation process of abrasive tools requires a lot of manpower and material resources, the manufacturing cost is high, and it does not meet the requirements of green manufacturing
