Problems solved by technology

Due to the small diameter, long length and high processing difficulty of the iron horse steel slender rod, it is very easy to bend and deform due to the insufficient rigidity of the iron horse steel slender rod in the process of turning the iron horse steel slender rod. Long rods are prone to processing defects such as corrugation, taper, multi-edge, bamboo and bending when they are stressed or heated, which brings greater processing difficulty to the processing of iron horse steel slender rods. The processing technology of rods needs to be improved urgently
Moreover, the bending deformation of the iron horse steel slender rods will also cause the vibration of the process system, thereby reducing the machining accuracy and surface roughness of the rods
[0003] In addition, when processing such iron horse steel slender rods, it is very easy to cause the raw material round steel to bend sideways due to operational factors such as improper clamping, so that the straightness and coaxiality of the iron horse steel slender rods cannot meet the requirements
[0004] Aiming at the technical problem that processing deformation is easily produced due to the lack of rigidity of iron horse steel slender rods during mechanical processing, the inventor intends to provide a processing method suitable for iron horse steel slender rods, by combining processing and detection in real time , from the aspect of processing technology to effectively reduce the deformation of iron horse steel slender rods during processing, so as to improve its processing quality and ensure that its dimensional accuracy meets the requirements

Abstract

The invention relates to a machining process method suitable for a long and thin iron-stainless steel rod piece. According to the machining process method suitable for the slender rod piece made of the ferritic stainless steel, machining and detection are combined in real time, deformation of the slender rod piece made of the ferritic stainless steel in the machining process is effectively reduced from the angle of the machining process, so that the machining quality of the slender rod piece is improved, and it is guaranteed that the size precision and the form and position precision of the slender rod piece meet the requirements. According to the method provided by the invention, machining is carried out in a one-jacking and one-clamping manner, and the follow rest is used within the full-length machining length of the slender rod piece made of the iron and stainless steel, so that the situation that the slender rod piece made of the iron and stainless steel is laterally bent due to improper clamping force is avoided. Meanwhile, according to the method provided by the invention, the feed amount is as small as possible, the pressure generated by a cutter on the slender rod piece made of the molten iron in each machining step is reduced, and the lateral bending of the slender rod piece made of the molten iron is reduced, so that the straightness of the slender rod piece made of the molten iron is controlled; and the requirement on the surface roughness of the slender iron-stainless steel rod piece can be better met by small feeding amount.

Description

technical field [0001] The invention belongs to the technical field of processing slender rods, and relates to a processing method suitable for iron horse steel slender rods. Background technique [0002] Iron horse steel material has the characteristics of high hardness, high strength, and difficult cutting process. Iron horse steel slender rods refer to iron horse steel rods with a ratio of length to diameter ≥ 20. Due to the small diameter, long length and high processing difficulty of the iron horse steel slender rod, it is very easy to bend and deform due to the insufficient rigidity of the iron horse steel slender rod in the process of turning the iron horse steel slender rod. Long rods are prone to processing defects such as corrugation, taper, multi-edge, bamboo and bending when they are stressed or heated, which brings greater processing difficulty to the processing of iron horse steel slender rods. The processing technology of rods needs to be improved urgently. ...
