A clamping mechanism for steel bar sawing CNC machine

Abstract

The invention provides a clamping mechanism for a CNC machine for sawing steel bars, which relates to the technical field of mechanical processing and includes: an outer support plate; an inner circulation guide frame is fixedly connected to the inner surface of the outer support plate by welding, and the inner circulation guide The frame includes a circulating outer rail and a circulating inner rail. The outer support plate is provided with two places, and the two outer support plates are fixedly connected by connecting rods; it has the function of auxiliary fixing and advancing the cut steel bars, and is applied to the steel bars. The middle position of the feeding mechanism and the steel bar cutting mechanism, the steel bars are clamped and fixed by multiple sets of steel bar fixing seats, and then the steel bars are assisted by the pulling mechanism to transfer the steel bars, and the auxiliary steel bar feeding mechanism assists and fixes the cut steel bars and pushes them synchronously. In the process of advancing the steel bar by the existing steel bar CNC cutting machine, the material is transported by a roller or a conveyor belt, which is prone to shaking during the transporting process, resulting in the unevenness of a group of steel bars to be cut, thereby affecting the accuracy of steel bar cutting.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a clamping mechanism for a CNC machine for sawing steel bars. Background technique [0002] At present, in the field of machining and construction, a large number of steel bars need to be used. In order to meet the needs of steel bar production and processing, it is often necessary to cut steel bars with different lengths. In the existing steel bar cutting equipment, in order to adapt to efficient processing To meet the needs of high-precision production and high-precision production, a large number of steel bar processing manufacturers use CNC machines to cut steel bars. It has the functions of automatic feeding, quantitative feeding and automatic workpiece transfer, which greatly saves manpower and material resources, so it has been widely used. [0003] For example, the patent with publication number CN201510622984.1 discloses a steel bar automatic cutting device...

AI Technical Summary

Problems solved by technology

[0004] However, as far as the current steel bar CNC cutting machine is concerned, when cutting the steel bar, it is necessary to arrange and fix the steel bar at the cutting position. When the existing steel bar CNC cutting machine advances the steel bar, the material is transported by a roller or a conveyor belt. , it is easy to shake during the transportation process, resulting in uneven cutting of a set of steel bars, thus affecting the accuracy of steel bar cutting
