High-speed reciprocating transverse cutting saw

Abstract

The invention provides a high-speed reciprocating transverse cutting saw comprising a cutting part. The cutting part comprises a cutting device. The cutting device comprises two cutting mechanism servo motors. Each cutting mechanism servo motor is connected with a first synchronous belt wheel, arranged on the other side of a servo motor fixing plate, through a first swing arm shaft. The two firstsynchronous belt wheels are in transmission connection through a belt. One first synchronous belt wheel is connected with a second synchronous belt wheel. A tensioning synchronous wheel is arranged above the second synchronous belt wheel. A third synchronous belt wheel is arranged above the tensioning synchronous wheel. The second synchronous belt wheel, the tensioning synchronous wheel and the third synchronous belt wheel are in transmission connection through a synchronous belt. The third synchronous belt wheel is connected with a saw web through a saw web shaft. The high-speed reciprocatingtransverse cutting saw is compact in structure, high in transmission efficiency, high in sawing precision, high in sawing speed, low in noise, easy to repair and maintain, small in installation spaceand low in failure rate, cost of repair and maintenance is reduced, and the device use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cutting saws, in particular to a high-speed reciprocating cross cutting saw. Background technique [0002] At present, whether it is a fast cross-cut saw or a preferred saw, the transmission mode of the saw blade is an ordinary three-phase asynchronous motor to drive the saw blade to rotate through a V-belt. Yes, the power is provided by the servo motor. [0003] Poor stability and easy to cut. In order to ensure the smooth progress of the sawing work, the aluminum plate (or other soft materials) installed at the saw kerf and the feeding guide installed to ensure that the sawing section meets the customer's requirements when sawing wood. [0004] Once the aluminum plate at the saw kerf and the feeding guide are cut too large by the saw blade, the cut wood head is easy to get stuck in this gap, and after it gets stuck, it will block the wood that enters the cutting area from the rear. At this time, if y...

Problems solved by technology

Therefore, it is more difficult for customers to maintain the equipment using this structure in the later period.

[0007] The ejector rod and the pendulum rod are connected by joint bearings. Frequent ups and downs cause the copper bushings in the joint bearings to be easily worn and cause the gap to be too large, so that the sawn wood does not meet the standard and generates noise.

[0008] In order to reduce the load of the motor, the swing rod is all made of aluminum. Compared with steel, the aluminum material is softer, and its wear resistance is poor. The connection between the joint bearing and the swing rod is realized by a pin shaft made of steel. Yes, the hardness of the pin shaft is obviously higher than that of aluminum, so the hole on the aluminum swing rod will be ground to a large size, resulting in excessive fit clearance, resulting in a decrease in sawing accuracy
