Description

Wire sawing machine for mounting wood cutting wire saw

technical field

The invention relates to the field of a wire saw machine for cutting wood, in particular to a wire saw machine for installing a wood cutting wire saw.

Background technique

There are currently two types of wire saws. One is to use steel wire to chisel out the saw teeth on one side of the steel wire, and the other is a very narrow saw blade. The cutting methods of these two saws have cutting performance only when the object to be cut is moving in the direction of the cutting edge. Therefore, when making a curve cut. There are two ways: one is that the workpiece moves in a curve relative to the wire saw, and the workpiece is required to have a rotary motion at this time. For example, when a circle is processed on a long board, the length direction restricts the rotational movement of the workpiece, and a complete circle cannot be processed. The other is the movement of the wire saw along the curve being machined. Also the length of the plank will limit the rotational movement of the saw frame. Therefore, if CNC machining is to be used, the control of the machine tool must achieve the linkage function of more than three axes. High demands are placed on the machine tool. The equipment cost is high, and it is not easy to popularize, popularize and apply. Therefore, curve cutting on such a long plate can only be done by engraving and milling.

In the prior art, such as the patent No. 94211675.5 is a kind of all-round steel wire saw blade, the saw blade has sawtooth arrangement on the steel wire cylindrical surface, and the sawtooth is arranged in the circle direction on the saw blade circumference, so it can be used for omnidirectional cutting. The teeth of this saw are chiseled on the cylindrical surface of the steel wire. Therefore, it has a lot of internal stress, which is very easy to break during use. But the saw blade with this structure is very difficult to manufacture. Not only the cost is high, but the production efficiency is low. It is easy to be partially damaged. If it is replaced, it will lead to high cost of use. If it is not replaced, it will affect the quality of the processed parts. Since the parts are in contact with the steel wire on the saw blade during cutting, the steel wire is easily damaged and cannot be repaired after being damaged. This kind of saw blade is very impractical in practical applications and is not conducive to widespread use. Especially the use on the CNC curve cutting machine puts forward higher requirements on the durability of the wire saw.

Moreover, the saw blade will produce a large amount of sawdust when cutting wood, and the sawdust is easy to be wedged on the sawtooth, affecting the cutting effect of the sawtooth. Therefore, according to the wood of different materials, saw blades with different densities of saw teeth are used. If the saw teeth are too densely distributed, the wood chips will easily block the saw teeth and affect the cutting effect; if the saw teeth are too far apart, the cutting force will be affected. Therefore, saw blades need to be replaced when cutting wood of different materials, so a variety of saw blades are spared, resulting in high cost.

Contents of the invention

The present invention solves the above-mentioned shortcomings of the prior art, and provides a wire saw machine for installing wood cutting wire saws. Its structural design is simple and reasonable, and it can realize omni-directional cutting.

The technical solution adopted by the present invention to solve the technical problem: the wire saw for cutting wood includes a steel wire, and a group of cylindrical saw sleeves are sheathed on the steel wire, and the outer surface of the saw sleeve is provided with a cutting surface for cutting.

Therefore, the saw blades are not easy to break and have a long service life; and the length of the steel wires is easy to cut According to the actual needs, string the saw cover with the required length on the steel wire. The length of the saw blade is easy to adjust. After the saw cover is worn out during cutting, you only need to replace the damaged saw cover.

In order to further improve, there is a spacer set on the steel wire between adjacent saw sets. The length of the spacer can be set according to the needs, and the role of the spacer is to adjust the distance between the saw sets, which can reduce the accumulation of sawdust on the saw blade and enhance the cutting effect of the saw blade.

The cutting surface is tapered. In this way, the saw cover has a circular platform structure, and the outer surface of the circular platform is a cutting surface with a tapered structure. In this way, the saw cover on the steel wire forms a saw blade that can cut 360 degrees in all directions. Moreover, the saw cover with this structure is easy to manufacture and low in cost. easily damaged.

This kind of wire sawing machine adopting the above-mentioned wire saw for cutting wood includes an upper fixing frame and a lower fixing frame for respectively fixing the upper and lower ends of the steel wire. On the frame, a push rod that pushes the sliding seat to slide back and forth is arranged on the frame, and the push rod is connected to the disc driven by the motor. The position of the screw hole on the disc can conveniently adjust the length of the disc according to the thickness of the processed material to adjust the reciprocating up and down distance of the saw frame. The reciprocating frequency is adjusted by the speed of the motor.

The outer end of the upper fixing frame is threadedly connected with an upper adjusting rod for adjusting the tightness of the saw sleeve, wherein the steel wire passes through the upper adjusting rod, and the lower end of the upper adjusting rod presses against the saw sleeve; the outer end of the lower fixing frame is threaded with an adjusting saw blade. The lower adjustment rod for the tightness of the sleeve, wherein the steel wire passes through the lower adjustment rod, and the upper end of the lower adjustment rod is pressed against the saw sleeve; the lower adjustment rod passes through the lower end of the lower fixing frame, and the lower end of the lower adjustment rod is threaded with a steel wire adjustment piece , wherein the lower end of the steel wire is fixed on the steel wire adjustment piece.

The upper fixed frame is fixed in the adjustment groove by fasteners, and the screw nut cover for adjusting the upper and lower positions of the upper fixed frame is installed on the sliding seat.

The frame is equipped with a clamping mechanism for clamping the wood. The clamping mechanism includes a support seat and a lower pressure rod fixed on the frame. The support seat is provided with a ball supporting the wood, and the outer end of the lower pressure rod is provided with a pressure rod. , the middle of the pressure rod is connected to the outer end of the lower pressure rod by rotation, the outer end of the pressure rod is provided with a pressure head for pressing wood, the inner end of the pressure rod is provided with a handle to make the outer end of the pressure rod tilt up, and the lower pressure rod is provided with a There is a spring against the underside of the handle.
