Problems solved by technology

Continued processing and polishing means secondary handling and secondary processing, which is time-consuming and laborious, which is not conducive to project cost and progress control; if not processed, it will directly affect the fullness and firmness of the butt joint of the later steel bars, which will affect the overall tensile performance of the butt steel bars, which is not conducive to the project quality

Abstract

The invention relates to the field of manufacturing equipment, in particular to steel bar connecting end polishing and threading equipment and the application method thereof. The equipment is characterized in that a rolling and threading device and a polishing device are arranged on a machine frame, the rolling and threading device is fixed to the machine frame, and the rolling and threading device is provided with a steel bar clamping position; the polishing device is located on one side of the clamping position, and the polishing device can move in the direction of the axis of the clamping position. The equipment has the advantages that steel bar burrs can be polished conveniently and quickly, secondary transfer and secondary machining are avoided, and then working efficiency is improved; meanwhile, burrs at the ends of butt joint steel bars are polished off, so that workers are prevented from being cut by the burrs at the ends of butt joint steel bars in the steel bar transfer process, and safety is guaranteed; furthermore, the number of threads in a connecting sleeve meets the butt joint requirement in the steel bar butt joint process, so that steel bar butt joint firmness is ensured and a project meets the quality requirement.

Description

technical field [0001] The invention relates to the field of manufacturing equipment, in particular to grinding and threading equipment for steel bar connection ends and an application method thereof. Background technique [0002] At present, the straight thread connection technology of steel bars is implemented by rib stripping and rolling technology. First, cut the end of the steel bar flat with a cutting machine; secondly, use a rolling threading machine to strip the ribs and roll the end; finally, use a connecting sleeve to butt the steel bar. And in the actual application process, it is found that in the process of cutting the end of the steel bar with a cutting machine and rolling and stripping the rib steel bar with a threading machine, it is easy to produce end burrs. On the one hand, the port burr is easy to cut the construction personnel during the construction process; on the other hand, when the connecting sleeve is used to connect the steel bar, due to the port...
