Technical Field

The invention relates to the technical field of cutting saws, in particular to an high-speed reciprocating transverse cutting saw.

Background

At present, the transmission mode of a saw cutting saw blade of a quick transverse cutting saw or a preferred saw is that a common three-phase asynchronous motor drives the saw blade to rotate through a triangular belt, the saw blade is lifted and fallen by using swing rods to lift and fall through an ejector rod, and power is supplied by a servo motor.

Poor stability and easy cutting. The aluminum plate (or other softer materials) arranged at the saw cut part for ensuring the saw cutting work to be carried out smoothly and the feed guiding rule arranged for ensuring that the saw cutting section meets the angle required by a client when the wood is cut.

The aluminum plate and the feed guide at the kerf are so large that the head of cut timber will easily get stuck in the gap as soon as the blade cuts the timber too far, and then block the timber from the rear into the cutting area.

The connection of the saw blade and the transmission motor is realized by a common triangular belt, the center height and the center distance of the transmission motor can change in the using process, for example, the triangular belt can be loosened and lengthened after periods of use, so that the triangular belt slips during transmission, and the transmission efficiency is low.

When the distance between the swing rod for mounting the saw blade and the center of the transmission motor is not proper, the tightness of the transmission belt is not when the swing rod rises and falls, the swing rod is damaged when the swing rod is too tight, and the swing rod is damaged when the swing rod works for a long time under the state, so that a bearing in the swing rod is damaged too early.

The ejector rod and the oscillating rod are connected through the knuckle bearing, so that a copper bush in the knuckle bearing is easily abraded to cause overlarge gap, the sawed timber does not reach the standard, and noise is generated.

The load of pendulum rod for lightening the motor all adopts the aluminium material, and the material of aluminium is compared steel and is soft partially, and its wearability is very poor, and joint bearing is connected with the pendulum rod and is realized through round pins that make with steel, and the hardness of round pin axle is obviously more high than aluminium, consequently can cause the hole on the aluminium pendulum rod to be ground greatly, causes the fit clearance too big, leads to saw cutting the precision to descend.

The present invention is new technologies, replacing the existing push rod type transmission mode, compared with the traditional structure, the present invention has the great improvement in the aspects of mechanical structure, transmission mode, stability, production efficiency, etc., and the present invention is suitable for large solid wood board manufacturers.
