Description

Frame saw machine guide mechanism

technical field

The utility model relates to a frame type saw machine guide mechanism, which belongs to the technical field of stone equipment.

Background technique

With the rapid development of the stone industry, in order to obtain wide-format stone slabs and improve the quality and efficiency of slab processing, diamond frame saws have emerged as the times require. During the working process of the diamond frame saw, the saw frame equipped with the diamond saw blade realizes reciprocating motion under the action of the guide mechanism, so as to cut the stone blocks.

At present, the guide mechanisms of frame saw machines are mainly hinge guides and rail guides. The former has high processing quality and long tool life in the processing process, but the structure is complex, and due to the requirements of installation accuracy, installation is difficult, the trajectory of the saw blade is not easy to determine, and the movement stability during the sawing process is poor. The commonly used structure of the latter includes V-shaped slider guide rail, V-shaped roller guide rail, guide post guide sleeve type static pressure guide rail, the guide rail type guide mechanism has a simple structure, which can ensure the installation accuracy; The existing rail-type guiding mechanism mainly adopts the horizontal linear motion mode. The cutting edge of the diamond in the sawtooth is not ideal, the chips cannot be removed in time, and the corresponding motion trajectory cannot be adjusted according to actual needs, and the "back support" cannot be formed to effectively protect the diamond. Particles fall off, which is not conducive to the improvement of the sawing quality and efficiency of the sawing machine.

Utility model content

In view of the deficiencies of the above two mechanisms, the purpose of this utility model is to provide a frame-type saw machine guide mechanism that can adjust the trajectory, and realize the adjustment of the trajectory of the saw frame, and improve the quality and efficiency of sawing blocks.

In order to achieve the above object, the utility model adopts the following technical solutions:

The guide mechanism of the frame saw machine includes a guide rail, at least one guide rail roller, a guide rail seat and an auxiliary support mechanism; there are four sets of guide rails, which are respectively arranged at the four corners of the saw frame. The guide rail rollers move on the guide rails, and the guide rail rollers pass through the guide rails. The roller shaft is hinged with the saw frame, and the guide rail seat used to support the guide rail is fixed on the frame. The guide rail surface of the guide rail includes a horizontal plane, a transitional plane and an inclined plane connected in sequence. The angle between the inclined plane and the horizontal plane is within the range of 1° to 3°. Inside, the auxiliary support mechanism is used to assist in bearing the axial sawing force during the sawing process.

Further, the guide rail is a rectangular guide rail.

Further, the auxiliary support mechanism includes an auxiliary support bracket, an auxiliary support wheel, an auxiliary support wheel shaft and an auxiliary support wheel guide rail, the upper end of the auxiliary support bracket is arranged on the lower surface of the saw frame, and the auxiliary support wheel is fixed on the auxiliary support bracket through the auxiliary support wheel shaft. At the lower end, the auxiliary support wheels move on the auxiliary support wheel guide rails, and the auxiliary support wheel guide rails are fixed on the frame.

Or, the auxiliary support mechanism includes an auxiliary support bracket, an auxiliary support wheel, an auxiliary support wheel shaft and an auxiliary support wheel guide rail, one end of the auxiliary support bracket is arranged on the upper surface of the frame, and the auxiliary support wheel is fixed on the other side of the auxiliary support bracket through the auxiliary support wheel shaft. At one end, the auxiliary support wheel moves on the auxiliary support wheel guide rail, and the auxiliary support wheel guide rail is fixed on the saw frame.

Further, the guide rail is set at a set distance from the saw frame.

Further, the inclination angle of the inclined surface in the guide rail surface can be adjusted.

Further, the guide rail can be replaced by a V-shaped roller guide rail, a V-shaped slider guide rail or a guide post guide sleeve type static pressure guide rail.

Further, the number of guide rail rollers is determined according to the load bearing capacity, and when the number is large, an arrangement of multiple rows and multiple rows can be adopted.

Adjust the inclination angle of the inclined guide rail surface according to the actual production requirements, the movement track of the saw blade changes from the traditional horizontal straight line to the curve formed by the combination of the inclined straight line and the horizontal straight line, and the saw blade moves according to the adjusted curve. As shown in Figure 2, the inclination angle θ of the inclined guide rail surface can be adjusted as required, so as to adjust the corresponding movement track of the saw frame. When sawing stone blocks, the inclined guide rail surface makes the diamonds in the sawtooth receive necessary impact when the saw blade feeds, so as to facilitate the sharpening of diamonds and improve the quality and efficiency of sawing. However, the inclination angle should not be too large, which will lead to too small radius of curvature of the theoretical trajectory curve, which will lead to too large swing of the saw frame and affect the stability of sawing; the inclination angle should not be too small, otherwise it will not be conducive to diamond sharpening.

The beneficial effects of the utility model are:

1. Since the saw blade has an inclined motion track, the saw blade will be impacted to a certain extent during the falling process, which is beneficial to the sharpening of the diamond in the saw tooth and improves the quality of sawing;

2. The inclined movement track of the saw blade also makes the cutting track on the stone block an inclined arc, so that the cooling water can rush out the chips along the inclined direction in the saw kerf, reduce the heat generation of the saw blade, and improve the service life of the saw teeth;

3. Adjust the inclination angle of the inclined guide rail surface according to actual needs, so as to adjust the corresponding movement track of the saw frame, so that the saw teeth form a "back support" and improve processing efficiency.
