Problems solved by technology
The thickness of the table metal of the traditional saw blade is the same at each position along the width direction, that is, the cross section is rectangular. For such a saw blade, the thickness gap between the table metal and the saw teeth is large, and the rigidity is not enough. It is prone to saw running, cutting deviation, etc., which affects cutting stability.

Abstract
The invention relates to a frame saw. The frame saw comprises a plurality of parallel saw blades. Each saw blade comprises strip-sheet-shaped table metal and a plurality of sawtooth installation parts arranged on one side of the table metal, wherein the sawtooth installation parts are formed in the mode of protruding outwards in the width direction of the table metal and are in peak shapes. Sawteeth are installed on the sawtooth installation parts. The frame saw is characterized in that the thickness of the ends, close to the sawteeth, of the table metal is larger than that of the ends, far away from the sawteeth, of the table metal. According to the frame saw, the saw blades break through the traditional table metal shape in which the cross section is rectangular, certain gradient is given to the table metal, the rigidity and the strength of the table metal are improved, the difference between the thickness of the table metal and the thickness of the sawteeth is reduced, the frame saw is beneficial for preventing saw deviating and cutting deviation, and cutting stability is improved.
Description
technical field [0001] The invention relates to a processing tool with a saw blade, in particular to a frame saw. Background technique [0002] The frame saw machine, also known as the gang saw machine and the saw machine, is a frame saw formed by tensioning multiple saw blades on the saw frame. The crank (or crankshaft) linkage mechanism drives the saw frame to reciprocate up and down or left and right, so that the assembly A machine that cuts block materials longitudinally with multiple saw blades on the saw frame. Frame saws are widely used because of their simple production process, convenient operation, and easy realization of continuous and automatic production. [0003] The saw blade of the frame saw includes a strip-shaped table metal, a plurality of sawtooth installation parts arranged on one side of the table metal, and sawtooth installed on the sawtooth installation parts. The thickness of the table metal of the traditional saw blade is the same at each position...
