Abstract

The invention discloses a modular high-speed cutting experimental platform based on a Hopkinson pressure bar device. The modular high-speed cutting experimental platform includes a pedestal and a high-speed camera; mounting holes are arranged in a pedestal bottom plate; one side of a pedestal vertical plate is fixedly provided with a knife rest mechanism, and a workpiece motion direction control mechanism is arranged on the pedestal bottom plate and located at the same side as the knife rest mechanism; the knife rest mechanism includes a knife rod gland fixed to one side of the pedestal vertical plate, a knife rod is fixed on the pedestal vertical plate through a fastening bolt, and the front end of the knife rod is equipped with a blade; the workpiece motion direction control mechanism includes a bearing seat, the top of the bearing seat is provided with an axial opening running through the a shaft hole, a workpiece installation shaft, and a top surface of the bearing seat is provided with scale lines along an axial direction of the shaft hole; and a through hole is arranged in the pedestal vertical plate. The experimental platform provided by the invention is simple in structure, can be matched with a Hopkinson pressure bar testing machine to conveniently and rapidly complete a high-speed cutting experiment and a high-speed cutting rapid knife falling experiment, and does not need a specially designed experimental device.

Description

technical field [0001] The invention belongs to the field of metal cutting, in particular to a high-speed cutting experiment platform used in the Hopkinson compression bar device technology. Background technique [0002] High-speed cutting technology is an advanced manufacturing technology that has risen rapidly in the past ten years, and represents the mainstream direction of modern processing technology. High-speed cutting processing technology has the characteristics of high processing efficiency, small cutting force, and a large amount of heat taken away by chips is too late to transfer to the workpiece, so that the thermal deformation of the workpiece is small. The high cutting speed and high feed rate make the excitation frequency of the machine tool much higher than the natural frequency of the "machine tool-workpiece-tool" system, and the workpiece is in a stable processing state, so that the parts can obtain higher machining accuracy. Therefore, high-speed cutting ...
