Embodiment

[0093] figure 1 It is a structural schematic diagram of the straightening machine 010 in the embodiment of the present invention. Please refer to figure 1 , this embodiment provides a straightening machine 010 , the straightening machine 010 includes a frame 100 , a driving mechanism 200 , a preliminary correction mechanism 300 , a fine correction mechanism 400 and a pair of output rollers 500 . The primary calibration mechanism 300 , the fine calibration mechanism 400 and the output roller pair 500 respectively have conveying channels. Each conveying channel is connected in turn. When this straightening machine 010 is in use, the parts to be straightened are introduced from the entrance of the primary school mechanism 300, and then pass through the conveying channels of the primary school mechanism 300, the fine school mechanism 400 and the output roller pair 500, and the school is completed in the process. straight, and finally lead out from the exit end of output roller ...

Abstract

The invention aims to solve the problem that an existing straightening machine is poor in straightening quality of a thin-walled bar and provides a straightening machine. The straightening machine comprises an initial straightening mechanism, a fine straightening mechanism, output roller pairs and a driving mechanism. The driving mechanism drives the initial straightening mechanism, the fine straightening mechanism, output roller pairs to operate so as to initially and finely straighten the bar, respectively, thereby obtaining the bar with the dimensional precision reaching the standard. Rollers used by the initial straightening mechanism have circumferential transmission slots and annular grooves are formed on the bottom faces of the transmission slots, so that the to-be-straightened bar has an escape space and is unlikely to be subjected to compressive deformation, and each annular groove divides the bottom face of each transmission slot into two surfaces, so that the to-be-straightened bar is uniformly stressed from different directions, and the bar is unlikely to be stressed to be out-of-round or damaged. The straightening machine provided by the invention has the beneficial effects that in the straightening process, the bar is uniformly stressed and the bar is deformed to have the escape groove and the bar is unlikely to be stressed to be out-of-round or damaged, so that the straightening machine provided by the invention can guarantee the straightening quality of the bar, and the bar with relatively high dimensional precision is obtained.

Description

technical field [0001] The present invention relates to the technical field of straightening equipment, in particular to a straightening machine. Background technique [0002] Thin-walled rods are commonly used mechanical parts, such as noodle rods. The structural rigidity of the thin-walled rod is low, and it is easy to be compressed to produce bending deformation or torsional deformation during use, so it cannot be used or needs to be straightened before use. [0003] Due to the low rigidity and strength of the thin-walled rods, which are easily deformed or damaged by force, the existing straightening machines are prone to torsional deformation or tearing of the workpiece to be straightened during the straightening process. Therefore, existing straightening machines have the problem of poor straightening quality of thin-walled rods. Contents of the invention [0004] The invention aims to provide a straightening machine to solve the problem of poor straightening qualit...
