Multi-angle sawtooth cutting device for hard alloy saw blade

Abstract

The invention discloses a multi-angle sawtooth cutting device for a hard alloy saw blade. The multi-angle sawtooth cutting device for the hard alloy saw blade comprises a cutting mechanism and a bearing mechanism; the cutting mechanism is installed on the upper end face of the bearing mechanism, and a limiting sliding barrel correspondingly slides for a corresponding distance in a sliding groove, so that the sawtooth machining angle is changed, and the sawtooth cutting flexibility is improved. According to the device, the other end of a curved bar is arranged in an inner cavity of a second fixing clamping plate and movably connected with the second fixing clamping plate; the top end of a push rod is connected with the inner side of a mounting plate, and the surface of a positioning plate is connected with a gear motor through a bolt, so that when the device cuts sawteeth of the hard alloy saw blade, an air cylinder drives a mounting plate to incline by a certain angle through the push rod so as to drive a cutting assembly to rotate by a certain angle, then sawtooth depth cutting is conducted on the saw blade, meanwhile, the up-down moving distance of the cutting assembly in the vertical direction can be adjusted through a bolt so that the sawtooth machining angle can be changed, and the machining requirement can be met conveniently.

Description

technical field [0001] The invention relates to the technical field of sawtooth cutting equipment, in particular to a multi-angle sawtooth cutting device for cemented carbide saw blades. Background technique [0002] When the band saw blade cuts bundled, multi-layered tubes, profiles, etc., for a single sawtooth, after entering the workpiece, the number of times of cutting in and out of the material will increase greatly compared to the solid material, such as 50mm×50mm Square tubes with a wall thickness of 5 mm are stacked in double layers, with 5 tubes in each layer (10 tubes in total), compared with a solid workpiece of the same size of 250 mm × 100 mm. When cutting a 250mm×100mm solid material, after a single sawtooth enters the workpiece, it generally cuts the material or not cuts the material only once, and the chips are continuous. However, when cutting a 50mm×50mm square tube with the same cross-sectional size, after a single sawtooth enters the workpiece, because t...
