Problems solved by technology

[0002] At present, most of the bar straightening machines are only suitable for straightening long straight bars or coiled bars, and for short bars, if ordinary rotary hub straightening machines or parallel roller straightening machines are used for straightening Straightening, every time a short bar is straightened, it is necessary to stop the machine to adjust the bending amount of the hole die or the pressure roller. At the same time, there is a certain empty straightening area at the head and tail of the bar, so the straightening of the short bar The accuracy and straightening efficiency are very unsatisfactory, and cannot meet the straightening needs of existing short bars

Abstract

The invention provides a straightening method and a straightening device of a short bar stock. The method comprises the following main steps of: sequentially welding dispersed short bar stocks end to end to form a continuous long bar stock; straightening by a precise straightening mechanism; and cutting the bar stocks in front and back of a straightened welding line to obtain the straightened short bar stocks. According to the device corresponding to the method disclosed by the invention, a color spraying and butt welding mechanism is additionally arranged between a conventional roller straightening mechanism and the precise straightening mechanism; and a welding line detecting and cutting mechanism is additionally arranged at the back of the precise straightening mechanism. According to the invention, the straightening efficiency and the straightening precision of the short bar stock can be effectively improved.

Description

technical field [0001] The invention relates to a machining method and device, in particular to a method and device for straightening short bars. Background technique [0002] At present, most of the bar straightening machines are only suitable for straightening long straight bars or coiled bars, and for short bars, if ordinary rotary hub straightening machines or parallel roller straightening machines are used for straightening Straightening, every time a short bar is straightened, it is necessary to stop the machine to adjust the bending amount of the hole die or the pressure roller. At the same time, there is a certain empty straightening area at the head and tail of the bar, so the straightening of the short bar The precision and straightening efficiency are all unsatisfactory, and cannot meet the straightening requirements of existing short bars. Contents of the invention [0003] The object of the present invention is to provide a method and device for straightening...
