Embodiment Construction
[0036] The present invention firstly provides a post-welding orthopedic method of a metal component, such as figure 1 and figure 2 shown, including the following steps:
[0037] Step 1. Organize the orthopedic experience, solidify it into the process guide, detect and measure the deformation after welding, determine the amount of deformation, and select the appropriate orthopedic parameters from the process guide;
[0038] When performing orthopedic operations on site, what kind of flame 1 should be used for thermal orthopedics, how much pressure should be used for mechanical orthopedics, matters to be paid attention to during the cooling process, and what conditions should be met for successful orthopedic surgery? With a set of mature experience and data, we can combine the operating characteristics and experience of common thermal orthopedics and mechanical orthopedics, the shape and amount of common post-weld deformation, the mechanical pressure corresponding to the requi...

Abstract
The invention discloses a postwelding shape-righting method for hardware and a flame and dry ice synchronous shape-righting device, aims to provide a postwelding shape-right method which adopts spheroidal dry ice particles and flame for synchronous shape righting in the combination of the advantages of both mechanical shape righting and heating shape righting together with the operation experiences after curing, solves the problems that conventional flame shape righting and mechanical shape righting cannot be easily controlled and adverse effects are taken on the inner quality of part materials, achieves the purposes of lowering the operation difficulty and improving the production efficiency, and meanwhile solves the problems on cooling time, shape righting time / temperature and residual stress in the postwelding shape righting process of the hardware, as well as experience inheritance. The invention also provides a postwelding flame and dry ice synchronous shape-righting device for hardware.
Description
technical field [0001] The invention relates to a post-welding orthopedic method for a metal component, in particular to a method for synchronously orthopedic using flame and dry ice, and a flame-dry ice synchronous orthopedic device. Background technique [0002] Aluminum alloy material has become an ideal material for reducing self-weight in the field of transportation due to its advantages of light weight, good corrosion resistance and easy extrusion method. Since the thermal conductivity of aluminum alloy is 5 times that of steel, and the thermal expansion coefficient is 2 times that of steel, when it is heated locally by the welding heat source, although corresponding deformation control measures are taken, deformation after welding is inevitable. The control of welding deformation has become one of the biggest welding difficulties for aluminum alloys. In order to ensure the shape and assembly accuracy requirements of the parts, it is necessary to perform post-welding ...
