Balance swinging lateral cutter

The utility model relates to a device for laterally cutting aeroconcrete blanks on production line of aeroconcrete products, belonging to the field of processing equipment of building material. The utility model includes a cutting frame and a crank connection rod mechanism arranged on one side of the cutting frame, wherein, a drive end of the crank connection rod mechanism is connected with a drive device, and the output end of the crank connection rod mechanism is connected with a swinging rod. The other end of the swinging rod is connected with a cutting wire swinging rack below the cutting frame. The utility model has the differences that the device is provided with at least two cutting wire swinging racks. Through the swinging rod, each cutting wire swinging rack is correspondingly connected with a crank connection rod which has a phase angle of 180 degrees with the crank connection rod. For the utility model is provided with the crank connection rod mechanism with a cross phase angle of 180 degrees, the cutting wire swinging racks swing positively and reversely when in cutting, thus the cutting force stressed on the aeroconcrete blank goes evenly so as to prevent the blank form shaking and effectively solve the problem of distortion and fracture of the semi-finished product after cutting. Meanwhile, for the stander is statically or dynamically balanced, the vibration reduces in order to further reliably guarantee the cutting quality.
