Accurate fixed-length cutting-off discharging machine for prestressed reinforcing steel bar

Abstract

The invention discloses an accurate fixed-length cutting-off discharging machine for a prestressed reinforcing steel bar. The accurate fixed-length cutting-off discharging machine for the prestressedreinforcing steel bar comprises a transmission mechanism, a material guiding and dimension fixing mechanism and a control system. The transmission mechanism comprises a motor, a motor shell, a gear box, a drive roller group and a cutter transmission assembly. The material guiding and dimension fixing mechanism comprises a material guiding groove, a material guiding groove door, material guiding groove door support pieces, material guiding groove door opening and closing levers, material guiding groove door opening and closing air cylinders and foot stools. The control system comprises a controller, approach switches and an electromagnetic valve. The controller is a PLC single-chip microcomputer controller and used for receiving sensor signals in the approach switches and sending instructions to the electromagnetic valve to control air cylinders of all links to work. The accurate fixed-length cutting-off discharging machine for the prestressed reinforcing steel bar is stable and reliable in operation, accurate in fixed-length cutting off, long in service life and fully automatic, the single-chip microcomputer controller conducts instruction work, so that independence and accuracy are achieved, automatic cutting, automatic discharging, fault warning, empty warning, digital display counting and other functions can be achieved, the work efficiency is significantly improved, and theproduction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of steel bar processing, in particular to a prestressed steel bar precision fixed-length cutting and blanking machine. Background technique [0002] The prestressed steel bars used in cement prefabricated parts such as railway sleepers, electric poles, pipe piles, culverts, prefabricated panels and housing industrialization have strict length error requirements. When the error exceeds a certain range, it will directly affect the quality of the prefabricated parts. , so that the bearing capacity is reduced, so now the corresponding machinery factories are developing prestressed steel bar fixed-length cutting and cutting machines that meet the industry standard length error, but each has its own strengths and weaknesses. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a prestressed steel bar precise fixed-length cutting and ...
