Machine with automatic feeding and discharging function for chamfering internal and external of large bar

Abstract

The invention discloses a large-bar machine with an automatic feeding and discharging function. The machine comprises a workpiece automatic feeding device, a headstock and a workpiece automatic discharging device, wherein the workpiece automatic feeding device and the workpiece automatic discharging device are connected with one side of an input end of the headstock and one side of an output end of the headstock respectively, so that workpiece automatic feeding and workpiece automatic discharging are realized. According to the machine with the automatic feeding and discharging function for chamfering the internal and the external of a large bar, the input end and the output end of the headstock are provided with the workpiece automatic feeding device and the workpiece automatic discharging device respectively, so that the automation of the processes of workpiece feeding, discharging and clamping is effectively realized, the production efficiency is improved, and the labor intensity is reduced; the structure is precise, the operation is simple, the work is reliable, and the control is convenient; and the machine can be effectively adapted to rapid clamping and machining of the bars with different diameters and different lengths, so that the machining efficiency of chamfering the internals and the externals of the large bars can be improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy equipment, in particular to an internal and external chamfering machine for large bars with automatic loading and unloading functions. Background technique [0002] According to the production process of hot-extruded steel pipes, after the round bars are cut to a certain length, it is necessary to perform internal and external chamfering and end-face turning on large bars with a diameter ranging from 160mm to 320mm and a length ranging from 400mm to 1000mm. At present, ordinary lathes are used for processing, which is a general-purpose machine tool on the market. Before processing, the workpiece is loaded into the machine tool with a crane, and then the three-jaw chuck is manually clamped sequentially. It is very inconvenient to clamp the workpiece and requires more cost. time, not only the accuracy of manual clamping and positioning is low, but also the labor intensity of workers is high and t...
