The method provided by the invention is simple in technological means, and the machined iron-horse-steel thin-wall pipe fitting is high in percent of pass and controllable in dimensional precision.

Description

technical field [0001] The invention belongs to the technical field of processing thin-walled pipe fittings, and relates to a processing method suitable for iron-horse steel thin-walled pipe fittings. Background technique [0002] Iron horse steel material has the characteristics of high hardness, high strength, and difficult cutting process. Iron horse steel thin-walled pipe fittings usually refer to iron horse steel pipe fittings whose wall thickness to inner diameter radius of curvature (or contour size) ratio is less than 1:20. The prominent features of Tiema steel thin-walled pipe fittings are thin wall and difficult processing. In the process of processing Tiema steel thin-walled pipe fittings by CNC turning, Tiema steel thin-walled pipe fittings are easily damaged due to factors such as insufficient strength, cutting heat, and cutting force.

The prominent features of Tiema steel thin-walled pipe fittings are thin wall and difficult processing. In the process of processing Tiema steel thin-walled pipe fittings by CNC turning, Tiema steel thin-walled pipe fittings are easily damaged due to factors such as insufficient strength, cutting heat, and cutting force. Deformation due to the influence of pipe fittings, affecting the dimensional accuracy and shape accuracy of the pipe fittings

Moreover, under the action of cutting force, the iron horse steel thin-walled pipe fittings are prone to vibration, thereby reducing the machining accuracy and surface roughness of the iron horse steel thin-walled pipe fittings

It can be seen that the traditional processing technology will bring a large amount of processing deformation to the processing of Tiema Steel thin-walled pipe fittings, and cannot guarantee the dimensional accuracy of Tiema Steel thin-walled pipe fittings. This is also the processing technology of Tiema Steel thin-walled pipe fittings. place

[0003] In addition, when processing this kind of iron horse steel thin-walled pipe fittings, it is very easy to cause the straightness and coaxiality of iron horse steel thin-walled pipe fittings to fail to meet the requirements due to operational factors such as improper clamping.

[0004] Aiming at the technical problem that the thin-walled pipe fittings of Tiema Steel are easily deformed due to insufficient strength during mechanical processing, the inventor intends to provide a processing method suitable for thin-walled pipe fittings of Tiema Steel. By combining processing and detection in real time, from The processing technology controls the angle to effectively reduce the deformation of iron horse steel thin-walled pipe fittings during processing, so as to improve its processing quality and ensure its dimensional accuracy requirements
