Problems solved by technology

[0003] In addition, in the traditional process, the surface of the workpiece is often strengthened first, and then the surface coating is processed. However, at this time, because the surface coating has been strengthened, it is extremely difficult to process with ordinary processing methods, especially high-quality wear-resistant coating

Abstract

The invention provides a metal surface strengthening combined machining device and method of laminar plasmas. The device comprises a laminar plasma spraying system (1), a control device (2) and a finish machining device (3); the control device (2) is electrically connected with the laminar plasma spraying system (1) and the finish machining device (3); a laminar plasma generator (101) of the laminar plasma spraying system (1) is parallel to a cutter (301) of the finish machining device (3); and the cutter (301) synchronously follows the laminar plasma generator (101) to axially move along workpieces to be treated. The method comprises the steps of: clamping of the workpieces on a worktable; resetting of the machining device; operation of the finish machining device during spraying by the laminar plasma generator; completion of the surface spraying of the workpieces and finish machining of coating layers; recovery of metal powder and chips; parking and taking down of the workpieces. Thedevice has the advantages of good controllability, high stability, good quality of the coating layers and high surface precision of the coating layers.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a laminar flow plasma metal surface strengthening composite processing device and method. Background technique [0002] With the continuous development of science and technology, mechanical equipment such as mining machinery and construction machinery have put forward higher and higher requirements for the surface wear resistance of some parts: on the one hand, the core of the parts is required to have high toughness and bending strength, and on the other hand On the one hand, parts are required to have higher surface hardness to improve their wear resistance. Plasma spraying / cladding techniques are often used to solve the above problems. However, although the traditional plasma (turbulent plasma jet) spraying / cladding surface strengthening treatment technology can prepare a coating with a specified thickness on the surface of the part to improve its wear resistance, the qua...
