Problems solved by technology

Although the method of driving the cam by the motor can obtain a high forging frequency, the machine is noisy and easy to be damaged. However, it is usually difficult to achieve a high forging frequency by directly driving the hammer head with hydraulic pressure, which limits the Improved material rate and section quality

Abstract

A radial asymmetric feeding device driven by the liquefied natural gas comprises a device body and a gas configuring mechanism and a material clamping mechanism which match with the device body. A feeding mechanism is composed of four sets of same striking and forging mechanisms distributed along the device body in the radial direction, feeding hammers are driven by the high pressure gas produced by liquefied natural gas combustion to apply the radial offset radial force to a bar or tube, the hammers of the four sets of striking and forging mechanisms strike the bar or tube sequentially to cause fatigue break of the bar or tube, and the feeding process is completed. The expansion gas produced by liquefied natural gas combustion is utilized to drive the feeding hammers to move so as to feed, so that pollution is reduced; on the basis of the low stress fatigue feeding method, the method of utilizing the explosion expansion of the liquefied natural gas combustion is adopted to drive the hammers and implement the precision feeding of metal bars and tubes; the device has the advantages of high producing efficiency, and less material consumption.

Description

technical field [0001] The invention belongs to the technical field of material processing machinery, and in particular relates to a radial asymmetric feeding device driven by liquefied natural gas. Background technique [0002] Metal rod tube material is the most basic form of blank used in industrial production, and its blanking problem is also the first step in manufacturing. Traditionally, lathes, band saws, thermal cutting machines, punching machines and other machines are used for processing. However, there are problems such as poor section quality, waste of materials and low production efficiency with these blanking mechanisms. The low-stress fatigue blanking method, which is still in the laboratory research stage, is to prefabricate an annular V-shaped groove in sections on the outer wall of the rod and tube material, and then clamp one end of the rod and tube material, and then clamp it to the cantilever end of the rod and tube material. High-frequency circumferent...
