Fixing device for steel bar cutting

Abstract

The invention relates to a fixing device for steel bar cutting. The fixing device for steel bar cutting comprises a base plate. A fixed clamping plate and a movable clamping plate are oppositely arranged on the upper surface of the base plate. The fixed clamping plate is fixedly arranged on the base plate. The movable clamping plate is movably arranged on the base plate. Positioning grooves sued for fixing steel bars are formed in the bottom of the fixed clamping plate and the bottom of the movable clamping plate. A guiding device and a transmission device are arranged outside the movable clamping plate. The transmission device drives the movable clamping plate to move front and back in the length direction of the base plate through the guiding device and is used for clamping or releasingsteel bars. The upper portion of a guiding groove formed by the fixed clamping plate and the movable clamping plate inclines outwards to be in a funnel shape, so that a guiding function is achieved, and steel bars can be placed in the guiding groove conveniently. The lower end of a positioning groove formed by the fixed clamping plate and the movable clamping plate is round and can tightly and firmly clamp round steel bars, and thus the end faces of the steel bars are made flush and perpendicular to the longitudinal axes of the steel bars.

Description

technical field [0001] The invention relates to the technical field of steel bar cutting and processing, in particular to a steel bar cutting and fixing device. Background technique [0002] In civil engineering construction, the mechanical connection process of upsetting straight threads of steel bars is currently mostly used. In order to ensure the uniform diameter of the upsetting parts of the steel bars and the integrity of the processed thread threads, it is required that the cutting end faces of the steel bars be strictly flush in addition to being round, that is, the end faces perpendicular to the longitudinal axis of the bar. In order to meet this requirement, grinding wheel cutters are generally used on construction sites to cut steel bars. The device for fixing the steel bar of the grinding wheel cutting machine is composed of a fixed flat steel plate and a movable flat steel plate. Since the contact surface is flat, it is difficult to fix the round steel bar well...

AI Technical Summary

Problems solved by technology

The device for fixing the steel bar of the grinding wheel cutting machine is composed of a fixed flat steel plate and a movable flat steel plate. Since the contact surface is flat, it is difficult to fix the round steel bar well, and the movable plate requires the worker to lean down and rotate frequently. If the distance between the screw and the screw is moved, not only the fixing effect is poor, but the end surface of the steel bar is uneven, which affects the quality of the steel bar connection, and it is time-consuming and labor-intensive. At the same time, there are safety hazards such as the steel bar slipping off and the cutting piece breaking and hurting people.
