Problems solved by technology
Although this kind of saw blade can reduce the possibility of the saw blade being clamped to a certain extent, the production cost of this kind of saw blade is significantly higher than that of ordinary saw blades. As the saw blade is constantly replaced in use, this cost disadvantage will be exaggerated.

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] Such as figure 1 As shown, an anti-pinch sawing machine based on sawing kerf temperature monitoring includes a main body of the sawing machine and a sawing kerf temperature monitoring device. The main body of the sawing machine includes a power motor, a workbench 2, a clamping hydraulic cylinder 3, a band saw blade 4, a driving saw disc 5, a driven saw disc 6, a tensioning hydraulic cylinder 7, a saw frame 8, the first feed guide column 9, the second Two feeding guide columns 10, a feeding hydraulic cylinder 11 and a sawing machine base 12.
[0027] The saw frame 8 and the saw machine base 12 form a sliding pair. Feed hydraulic cylinder 11 is fixed with saw machine base 12. The piston rod of feed hydraulic cylinder is fixed with saw frame 8. The piston rod of the feed hydraulic cylinder is arranged vertically. The tensioning hydraulic cylinder 7 is fixed on the ...

The invention discloses a clamping prevention sawbed based on saw joint temperature monitoring and a clamping prevention method thereof. The clamping prevention sawbed based on saw joint temperature monitoring comprises a sawbed body and a saw joint temperature monitoring device. The sawbed body comprises a power motor, a workbench, a clamping hydraulic cylinder, a band saw blade, a driving saw plate, a driven saw plate, a tensioning hydraulic cylinder, a saw holder, a first feeding guide pin, a second feeding guide pin, a feeding hydraulic cylinder and a sawbed base. The saw joint temperaturemonitoring device comprises a linear sliding table, a temperature sensor, electric heating wires, first electrodes and second electrodes. One ends of the n electric heating wires are connected with the n first electrodes separately, and the other ends of the n electric heating wires are connected with the n second electrodes separately. The n electric heating wires are horizontally arranged. By monitoring the saw joint temperature in real time and controlling the temperature, the temperature in saw joints is uniform, stress distribution of the saw joints is uniform accordingly, and the problem that workpieces are clamped when cut by a band saw blade can be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of sawing, and in particular relates to an anti-pinch sawing machine based on sawing kerf temperature monitoring and an anti-pinch method thereof. Background technique [0002] Metal band sawing machines are often called "industrial mother machines". Efficient metal band sawing technology is widely used in metal and non-metallic material processing industries. The advanced level of metal band sawing technology must reflect the development of a country's manufacturing industry. . However, because the sawtooth load of the band saw blade involved in sawing is affected by the complex nonlinear vibration characteristics of the saw band and the nonlinear characteristics of the feeding process, the movement of the band saw blade in the feeding direction will be hindered to a certain extent. Especially when the band saw blade is processing large workpieces, it is prone to the situation that the saw kerf shrinks and...
