Problems solved by technology

[0006] Arc spraying has high deposition efficiency, but low coating hardness; brush plating can obtain high-strength and high-hardness coatings, good mechanical properties, but low deposition speed, combining the two is an ideal rapid mold manufacturing method
[0007] At present, arc spraying and brush plating are mostly manual operations. When the surface area of ​​the mold is too large, the labor intensity of arc spraying and brush plating is too large, the manual operation is unbearable, and the quality of the mold cannot be guaranteed.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 A block diagram of rapid manufacturing technology for arc spraying-brush plating compound forming metal spraying mold is given. The master mold to be sprayed can be RP prototype or transition model, non-metallic model obtained by CNC machining, physical sample of parts, etc. Before spraying, the surface of the master mold is polished (first coat a layer of release agent, and then evenly coat a layer of release agent, let it stand for about 30 minutes), and then spray the mold metal with an arc spray gun to form a thin metal shell with a certain thickness. During the working process, the axis of the spray gun is always perpendicular to the curved surface where the working point is located. After the spraying is completed, the unnecessary parts are cut off, and then the resin, filler and other backing materials are poured into the pre-prepared ...

Abstract

A method for using 3D CAD data to directly drive the dedicated robot used to metal arc spray on the punch die of the covering part for car includes such steps as generating the 3D CAD data of said punch die, hierarchica process of data model, slicing layer by layer, coordinate transform between the coordinate systems of computer and die-making equipment, and movement, control.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, specifically relates to rapid mold manufacturing technology based on rapid prototyping technology, relates to the development of new automobile models and the trial production of prototypes, and in particular to a method for the robot movement of metal arc spraying rapid manufacturing molds directly driven by three-dimensional CAD data . Background technique [0002] Combining traditional mold manufacturing technology with CAD / RE, RP and other technologies to provide fast and low-cost system integration technology for new product development is a new type of rapid mold manufacturing technology. In order to realize brush plating / electroforming-arc spraying compound molding mold manufacturing technology and develop corresponding integrated intelligent equipment, it is necessary to study suitable layered processing technology for three-dimensional solid parts, develop corresponding s...
