Description

Abrasive tool manufacturing method based on 3D printing

Technical field

The invention relates to a method for manufacturing an abrasive tool, in particular to a method for manufacturing an abrasive tool based on 3D printing.

Background technique

At present, the grinding tools on the market are all cast from a mold, and the resin, the abrasive and some auxiliary materials are poured into the mold to form and solidify. The production process generally includes the following processes: molding, batching, compounding, press molding, dry solidification molding or high temperature firing. Since the prior art manufacturing abrasive tools require a mold, the mold must be opened to cast the production, but the mold is opened. The cost is high and the cycle is long, which causes the factory to be mass-produced. This method of high cost, long cycle, and batch production is unable to meet the requirements of today's diversified, diversified and fast-moving markets.

At the same time, because the cycle of the above production process is very long, and the factory needs mass production to ensure economic benefits, it also requires the factory to maintain a large inventory of large quantities to meet the production needs. However, certain abrasives in abrasive tools have a short shelf life, so in a relatively short period of time, the factory must consume all of the inventory, otherwise the abrasives will become waste after they expire, causing damage to the plant.

technical problem

Since the proportion of various components in the abrasive tool is very important, each manufacturer has strict confidentiality of its own formula, so only a professional factory or engineer with many years of experience can produce it, which cannot meet the needs of the vast market, and when designed When a new abrasive tool is used, the mold must be re-opened, and the manufacturer must consider the cost of mold opening. In the case of insufficient market demand, the manufacturer generally does not open a mold for a new product, resulting in lag in research and development and production, which is not conducive to industry. The development of production.

Technical solution

OBJECT OF THE INVENTION The object of the present invention is to solve the problem of manufacturing a mold in a prior art and which is time consuming and costly, and to provide a method for manufacturing an abrasive tool based on 3D printing.

Technical Solution: The 3D printing-based abrasive manufacturing method of the present invention is achieved by the method of manufacturing a 3D printing-based abrasive tool, comprising the following steps:

1) Generate a 3D solid model corresponding to the grinding tool on the computer side, including constructing a 3D solid model corresponding to the mold by engineering drawing software or a 3D scanning camera (for example, a depth sensing camera) or a 3D physical scanner, and mapping the 3D solid model To the printing software of the 3D printer;

2) Select appropriate 3D printing consumables according to the molding process of the abrasive tool and the 3D printing process, and assemble into a 3D printer;

3) Configuring a 3D printer, including configuring a sensor component of the printer to control the output positioning of the printer; configuring a processor component of the printer to control the printer print path; and configuring a timing component of the printer to control the operation of each processing component time;

4) The print job, the 3D printer receives the command to print the physical grinder.

When the grinding tool has a plurality of independent structures that are not fixed to each other, in the step 1), the independent structures of the grinding tool are split, and the corresponding 3D model entities are separately formed and printed separately.

In the step 2), the abrasive and the auxiliary material are selected according to the abrasive tool, and the abrasive and various auxiliary materials are prepared, mixed into a polymer raw material which can be injection molded, blow molded, extruded, etc., and mixed to prepare a consumable for 3D printing. .

In the step 4), the environmental conditions of the 3D printer working section, including temperature, humidity, gas composition and content, are controlled according to the abrasive forming process.

The 3D printing-based abrasive manufacturing method further includes storing a corresponding 3D solid model of the grinding tool through a storage medium.

Beneficial effect

The 3D printing-based grinding tool manufacturing method of the invention can produce various kinds of abrasive tools of various shapes at any time without opening the mold, and it is desirable to wait for several months. No need for mass production, single piece of abrasive can also be made. Low cost, zero inventory. It can be used in factories of all sizes and even in personal households to manufacture the abrasive tools you need. You only need to have a desktop 3D printer. You can print your own 3D printing supplies with abrasive materials. The required abrasive tools.
