Steel bar straight thread threading machine with automatic cutting and grinding functions

Abstract

The invention relates to the technical field of steel bar straight thread threading machines, in particular to a steel bar straight thread threading machine with an automatic cutting and polishing function, which comprises a base, a fixing mechanism arranged on the base, a first groove formed in the base, a displacement groove formed in the first groove, a cutting device with a polishing function arranged in the first groove, and a threading mechanism arranged on one side of the cutting device. After the reinforcing steel bar is cut, the motor continues to drive the lead screw to rotate, at the moment, a first bearing is extruded by an inclined groove in the upper section of the displacement groove, the first bearing rotates along the inclined groove, meanwhile, the first bearing drives an L-shaped support through a second shaft, and the L-shaped support drives a sliding block to move along a guide rail till the first bearing rotates from one set of linear grooves to the other set of linear grooves; at the moment, the cutting blade and the end of the reinforcing steel bar are pulled open, the lead screw continues to rotate, the axis of the grinding wheel and the axis of the end of the reinforcing steel bar are located on the same straight line, and the butt-joint sleeve is prevented from bumping the end of the reinforcing steel bar and grinding of the end of the reinforcing steel bar is facilitated.

Description

technical field [0001] The invention relates to the technical field of a steel bar straight thread threading machine, in particular to a steel bar straight thread threading machine with automatic cutting and polishing. Background technique [0002] At present, the processing technology of steel bars is developing rapidly. Sometimes the steel bars need to be lengthened to meet the requirements, and the steel bars need to be threaded to facilitate the butt joint of the steel bars. Yet reinforcing bar is before threading, and some reinforcing bars need to be cut to front end earlier, and existing reinforcing bar threading machine is made up of base, fixed mechanism, cutting mechanism, threading mechanism, and reinforcing bar is fixed on the fixed mechanism. [0003] The cutting mechanism set on the steel wire machine is used to cut the steel bar, but after the end of the steel bar is cut, the end face of the steel bar is very sharp with burrs protruding, which is very dangerous...

AI Technical Summary

Problems solved by technology

[0003] The cutting mechanism set on the steel wire machine is used to cut the steel bar, but after the end of the steel bar is cut, the end face of the steel bar is very sharp with burrs protruding, which is very dangerous for the construction workers and is not conducive to the next Steel bars are threaded, for this reason, the present invention proposes a steel bar straight thread threading machine with automatic cutting and grinding to solve the above problems
