Ultrahigh-speed horizontal band sawing machine

Abstract

The invention discloses an ultrahigh-speed horizontal band sawing machine. The ultrahigh-speed horizontal band sawing machine comprises a base, a vertical column, a machine table and a sawing frame and further comprises a servo driving system and a sawing frame lifting balance system. The servo driving system comprises a servo motor, a decelerator and a ball lead screw. The decelerator is mountedon the vertical column, the ball lead screw is connected with the sawing frame, and the servo motor drives the sawing frame to rise and fall by driving the ball lead screw to rotate. The sawing framelifting balance system is used for reducing the axial linear load of the servo motor and provided with symmetrically arranged oil cylinders, a hose and an energy storage device. The lower ends of theoil cylinders are fixed to the base, the upper ends of the oil cylinders are connected with the sawing frame, and the energy storage device is connected with the two oil cylinders through the hose. The sawing frame is inclined forwards relative to the vertical column to be arranged. According to the ultrahigh-speed horizontal band sawing machine, the design that the rear inclination angle of a traditional sawing frame is 35 degrees is changed, the design that the front inclination angle is 12 degrees is adopted, thus the overall gravity center of the sawing frame and the motion axis are basically overlapped, the mechanical state of lifting motion of the sawing frame in the sawing process is changed, moment of rotation in the Y-axis direction of the sawing frame is eliminated, friction resistance between a sliding sleeve and the vertical column during lifting motion of the sawing frame is reduced, and the service life of the machine is prolonged.

Description

technical field [0001] The invention belongs to the field of band sawing machine equipment, in particular to an ultra-high-speed horizontal band sawing machine. Background technique [0002] In the prior art, a band sawing machine is a machine tool used for sawing workpieces in the field of mechanical processing. Its sawing tool is a saw band. The saw frame of a common band sawing machine on the market is usually set backwards by 35°. The saw band is twisted to the vertical direction by the twisting mechanism and then saws the workpiece. However, the frictional resistance between the sliding sleeve and the column during the lifting movement of the traditional structural saw frame is very large, and the rotational moment of the saw frame in the Y-axis direction is also very large, which easily leads to equipment damage. [0003] In addition, since the back force of the saw band changes with the material, shape, hardness, etc. of the material during the sawing process, the sa...
