Description

Technical Field

[0001] The present application relates to the technical field of machine tool measurement and control parts, and in particular to a length measuring device for an aluminum bar hot shearing machine. Background Art

[0002] Aluminum bar hot shear is an industrial equipment specially used for shearing aluminum bars or aluminum alloy materials under high temperature, and is widely used in aluminum alloy processing industry. Aluminum bar hot shear usually includes a loading device for conveying heated long aluminum bars, a shearing device for shearing long aluminum bars, a unloading device for conveying sheared short aluminum bars, and a fixed-length measuring device for limiting and measuring the length of short aluminum bars. The fixed-length measuring device of the prior art simply designs a screw mechanism to adjust the front and rear direction of the travel switch, and measures and controls the length of the short aluminum bar by extruding the aluminum bar through the travel switch, but it still has the following problems: the longitudinal height cannot be adjusted.

[0003] Firstly, after the aluminum rod is cut, it sticks to the shear knife and moves upward with the shear knife for a distance. At this time, the aluminum rod will touch the bottom of the travel switch. After long-term use, the end of the travel switch has freedom of movement in the up and down directions and droops under the action of gravity. The travel switch cannot be accurately aligned with the center of the aluminum rod, affecting the shearing accuracy; then, when the length-to-diameter ratio of the short aluminum rod changes, the degree of downward deformation due to gravity also changes, and the longitudinal position of the travel switch needs to be adjusted for compensation.
