Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a bar material measuring device and aviation alloy bar material cutting equipment. Background Art

[0002] The prior art aviation material cutting equipment usually calculates the required cutting length based on the weight and density of the required bar when the outer diameter of the bar is constant. However, the bar is usually a hollow structure, which makes it easy for the calculation of the cutting length of the bar to deviate, resulting in material waste or inconsistent material weight.

[0003] The Chinese invention with application number 202110655556.4 discloses a device that can improve the quantitative cutting accuracy of alloy bars, which includes a feeding device and a measuring device. The feeding device is provided with a non-powered ramp material channel, an axial positioning baffle, and a pneumatic stop and feed device. An axial positioning baffle is provided on one side of the non-powered ramp material channel, and a pneumatic stop and feed device corresponding to the alloy bar to be cut is provided at the lower end of the non-powered ramp material channel; the measuring device includes a length measuring device, a weight measuring device and a diameter gauge, wherein: at the position corresponding to the pneumatic stop and feed device and the non-powered ramp material channel, a length measuring device is provided on the outer side of one end of the alloy bar to be cut away from the axial positioning baffle; a weight measuring device is provided in the direction where the alloy bar to be cut rolls away from the non-powered ramp material channel by its own weight, and a diameter gauge is provided in the direction where the alloy bar to be cut slides away from the weight measuring device. The device can obtain the actual length of each segmented section by automatically measuring the weight, length, and diameter of the cut alloy bar at different cross sections, and accurately control the weight of each segment of the alloy bar to be cut. However, during the loading process, the device needs to use a linear bearing to push the end face of the alloy bar to be cut against the axial positioning baffle before the length of the bar can be measured. After measuring the length, it needs to be transported forward by an electric push rod after the weight is measured by a weight measuring device. Two pushing devices are required. Therefore, the device requires more driving mechanisms, which makes its structure complex and costly. Utility Model Content
