Automatic material changing and feeding device for multi-specification steel bars

Abstract

The invention provides an automatic material changing and feeding device for multi-specification steel bars. The automatic material changing and feeding device comprises a mounting plate connected with a main machine, a sliding rail and a driving device are mounted on the mounting plate, and the driving device can move along the sliding rail; an upper driving wheel and a lower driving wheel whichcan clamp the steel bars for conveying are mounted on the driving device; a bracket is mounted on the mounting plate, a transmission device driven by a hydraulic motor is mounted on the bracket, and adistribution frame which can realize locking and conveying of the multi-specification steel bars conduct reciprocating movement along a guide rail and the transmission device; and a displacement sensor controls starting and stopping of a hydraulic cylinder and the hydraulic motor. The automatic material changing and feeding device has the beneficial effects that one-time material preparation canbe achieved, the multiple sets of steel bars with different specifications penetrate into simultaneously, the automatic material changing and feeding device is controlled by a sensor and driven by hydraulic pressure, automatic conveying and material changing are achieved stably and accurately, and conveying of the singe bar and double bars with the same specification can be automatically switched,transmission is stable, and the automation degree is high.

Description

technical field [0001] The invention relates to a numerically controlled steel bar bending machine, in particular to a multi-standard steel bar automatic refueling and feeding device of the numerically controlled steel bar bending machine. Background technique [0002] In the work of CNC steel bar bending machine, more and more steel bar specifications are used. At present, my country's CNC steel bar bending machine can process steel bars of different specifications on the same equipment, but only one specification can be processed at the same time. Steel bars, so in a production cycle of steel bar processing, it is necessary to change and feed materials many times, which has low safety and low efficiency. Contents of the invention [0003] The invention provides a feeding device for automatic refueling of multi-standard steel bars. Its purpose is to prepare materials at one time and penetrate multiple groups of steel bars with different specifications at the same time. It ...
