Automatic steel bar feeding device and cutting-off machine

Abstract

The invention provides an automatic steel bar feeding device and a cutting-off machine and belongs to the technical field of machines. The problems that an existing feeding device is poor in universality and prone to causing damage to the surfaces of steel bars are solved. The automatic steel bar feeding device comprises a bar material storage frame and a bar material conveying frame arranged on one side of the bar material storage frame, wherein the bar material conveying frame is rotationally connected with a plurality of conveying wheels for carrying workpieces; a stop plate used for limiting the workpieces from sliding downwards is fixed to the bar material storage frame, and the upper end surface of the stop plate is an inclined surface; and a pushing structure capable of pushing the workpiece abutting against the stop plate to the upper end surface of the stop plate is arranged below a material storage tabletop. The automatic steel bar feeding device is used for conveying steel bars, and the steel bars naturally slide downwards until being stopped by the stop plate; the pushing structure pushes one steel bar abutting against the stop plate upwards, and the steel bar slides downwards into one conveying wheel along the upper end surface of the stop plate; the conveying wheels have friction with the steel bars and drive the steel bars to move forwards in the axial direction, and automatic conveying of the steel bars is realized.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a feeding device, in particular to an automatic feeding device for steel rods. [0002] The invention belongs to the technical field of machinery, and relates to a cutting device, in particular to a cutting machine. Background technique [0003] In metalworking, straight steel rods are cut into short bars to desired lengths for subsequent processing, such as rivets, bolts, pins and shafts. All the existing cutting machines need manual feeding, which has the problem of high labor intensity. [0004] Known by consulting the literature, although there is an automatic feeding device for steel rods on record in the literature, such as the automatic feeding device for bars (CN201030440Y) recorded in the Chinese patent literature, and the automatic steel rod feeding machine (CN201214122Y); but due to the poor versatility of the above-mentioned feeding device , It is easy to cause prob...
