Special robot of die for rapid manufacture of covering piece for automobile by metal arc-spraying

Abstract

The invention discloses a metal arc painting fast mould-producing robot which can produce the punching die of car cover elements fast and economically. The robot integrates the electric paint and electric brush plating, and it is made up of movement and craft parameter controller, electric arc paint device, electric brush plating device and mechanical body. The robot is five variances rectangular coordination structure, the allocation mechanism uses gantry structure and has three movement variances, which is used to adjust the space position of ejection gun or plating pole, wrist has two rotation variances for adjusting the space posture of election gun or plating pole. The wrist part is designed with two parallelogram structure, realizes the decoupling of rotation variances and movement variances, makes the adjustment of posture not affect the space position of the working place. The robot uses CAD model as input, and is driven by CAD data, neední»t to program manually.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, relates to rapid mold manufacturing technology based on rapid prototyping technology, relates to the development of new automobile models and trial production of prototypes, and in particular to a robot for rapidly manufacturing molds by metal arc spraying. Background technique [0002] Rapid tooling manufacturing technology is relative to the traditional method of using numerical control machining to produce steel molds. Rapid tooling (Rapid Tooling-RT) is a mold manufacturing technology that uses rapid prototyping technology (Rapid Prototyping-RP) to produce mold prototypes or master molds. [0003] The metal arc spraying molding process refers to the use of arc spraying to quickly deposit a dense low-melting point metal thin shell on the RP prototype or the transition mold remade from the RP prototype, and then reinforce it with resin, metal composite materials, etc., so that ...

AI Technical Summary

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.
