Embodiment Construction

[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0017] Such as Figure 2A , 2B and image 3 As shown, the working environment of the substrate preheater 1 is high temperature and dusty, and at the same time it is required to heat up rapidly and maintain a constant temperature. Therefore, the system of the present invention adopts the following structure: comprising a substrate preheater 7 and its temperature control device, wherein The substrate preheater 7 is a box structure with a base plate 15, an inner wall 12 and an outer wall 11 arranged around the base plate 15, an insulating material 17 is arranged between the inner wall 12 and the outer wall 11, and the base plate 15 is installed through a heat insulating material 18. There is an electric heating tube 20, and a copper plate 16 is installed in the casing and above the electric heating tube 20, and the terminal of the electric ...

Abstract

The invention relates to a basic plate preheating system of laser metal deposition shaping. The basic plate preheating system comprises a basic plate pre-heater and a temperature control device thereof, wherein, the basic plate pre-heater has a box structure and is provided with a bottom plate, internal walls and external walls arranged around the bottom plate; heat insulating materials are arranged between the internal walls and the external walls; an electric heating pipe is installed on the bottom plate by the heat insulating materials and copper plates are arranged in the box body and over the electric heating pipe; and a wiring terminal of the electric heating pipe is connected with the temperature control device. The basic plate preheating system provides a stable temperature field for the laser metal deposition shaping technique, effectively reduces the temperature gradient of a sample and the basic plate during the shaping, and has high automation, good uniformity in preheating of the basic plate and high control precision, thus providing an effective solution to cracks or even breaks existing in the laser metal deposition shaping technique.

Description

technical field [0001] The invention relates to a substrate preheating system for laser metal deposition forming. Specifically, in the process of laser metal deposition forming, through a substrate preheater, a corresponding hardware integrated control unit and a software operation interface, it can achieve different substrate preheating temperatures. Substrate preheating system for laser metal deposition shaping of metal parts. Background technique [0002] Rapid Prototyping (hereinafter referred to as RP) technology is a high-tech developed in the 1990s. It is integrated and developed on the basis of computer-aided design (CAD, Computer Aided Design), computer-aided manufacturing (CAM, Computer Aided Manufacturing) technology, laser technology, computer numerical control technology, precision servo drive technology and new material technology. In the case of any cutting tools, molds and fixtures, the design scheme of any complex shape can be quickly converted into a three...
