Description

Technical Field

[0001] This invention relates to the field of stone processing wire saws, specifically a roller wire saw with adjustable cutting direction. Background Technology

[0002] With the rapid development of modern industrial technology, the stone processing industry is also gradually upgrading its production processes and equipment. Among them, multi-wire stone cutting machines utilize multiple cutting lines to cut raw stone blocks simultaneously, enabling the completion of more cutting tasks per unit time, significantly shortening the stone cutting production cycle, and greatly improving cutting efficiency and quality, representing a significant breakthrough in stone processing technology. Existing roller saws (such as those shown in Chinese patent CN223265999U) cut stone blocks by placing them on a lifting frame and slowly bringing them into contact with the cutting lines. However, raw stone blocks are usually cubic in shape, while the cutting lines of existing roller saws are horizontally arranged. When the cutting lines enter the stone, they contact the entire upper surface of the stone, resulting in excessively long contact lengths and extremely high cutting resistance. Consequently, problems such as large tension fluctuations in the saw, severe heat generation, and accelerated wire fatigue arise. To prevent the cutting lines from breaking or chipping, the feed speed must be reduced. Although the contact area is large, the effective cutting volume per unit time decreases instead of increasing. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a roller wire saw with adjustable cutting direction, which can adjust the cutting direction during cutting, reduce the area of ​​direct contact between the cutting line and the stone, and improve the stability and efficiency of cutting.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A roller wire saw with adjustable cutting direction includes a roller frame, a tension adjustment assembly, a take-up and undo assembly, a lifting frame, and a base. Four roller rollers are installed inside the roller frame. The tension adjustment assembly and the take-up and undo assembly are installed outside the roller frame. The lifting frame is elliptical and rotatable on the base and is used to lift and tumble stone. A rotating shaft is provided in the middle of the lower part of the roller frame, and a rotating seat is formed on the base. The rotating shaft is rotatably inserted into the rotating seat.

[0006] Furthermore, telescopic cylinders are installed on both sides of the lower part of the roller frame. The upper end of the telescopic cylinder is hinged to the roller frame, and the lower end of the telescopic cylinder is hinged to the base.

[0007] Furthermore, there are four telescopic cylinders, which are respectively installed at the four corners of the lower part of the roller frame.

[0008] Furthermore, the telescopic cylinder is a telescopic hydraulic cylinder.

[0009] Furthermore, a crossbeam is provided at the upper end of the base, and the rotating seat is mounted on the crossbeam.

[0010] Furthermore, a roller seat is provided between the roller roller and the roller frame, the roller seat is detachably installed on the roller frame, and the roller roller is rotatably inserted into the roller seat.

[0011] Furthermore, the roller seat and the roller frame are detachably fixed together by bolts.

[0012] Furthermore, the tension adjustment assembly includes an adjustment bracket, an adjustment wheel, an adjustment seat, a tension bracket, a tension wheel, a tension seat, a reversing bracket, a reversing wheel, and a reversing seat; the adjustment seat is fixedly installed on the side wall of the roller frame, the adjustment bracket is laterally movable on the adjustment seat, and the adjustment wheel is rotatably installed on the adjustment bracket; the tension seat is fixedly installed on the side wall of the roller frame, the tension bracket is rotatably installed on the tension seat, and the tension wheel is rotatably installed at the end of the tension bracket; the reversing seat is fixedly installed on the side wall of the roller frame, the reversing bracket is laterally movable on the reversing seat, and there are two reversing wheels, with their shafts installed perpendicularly to each other, and each of the two reversing wheels is rotatably installed on the reversing bracket.

[0013] Furthermore, the take-up and release assembly includes a take-up and release frame, take-up and release rollers, and a take-up and release motor; the take-up and release motor is fixedly mounted on the take-up and release frame, the take-up and release frame is fixedly mounted on the side wall of the roller frame, the take-up and release motor is fixedly mounted on the take-up and release frame, and the take-up and release rollers are fixedly connected to the output shaft of the take-up and release motor.

[0014] Furthermore, the lifting frame includes a base frame and longitudinal frames. The longitudinal frames are vertically fixed on the base. There are four longitudinal frames, which are respectively installed at the four corners of the base frame. The base frame can be lifted and lowered on the longitudinal frames. The base frame and the longitudinal frames are connected by ball screws.

[0015] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0016] 1. Through the cooperation of the rotating shaft and the rotating seat, the roller frame can rotate at a certain angle relative to the base. In this way, when the stone is lifted and cut, the operator can rotate the roller frame to adjust the appropriate cutting direction. Furthermore, during the cutting process, the cutting angle can be adjusted according to different working conditions, thereby reducing the contact area between the cutting line and the stone. This effectively avoids excessive contact length between the cutting line and the stone, preventing problems such as large tension fluctuations, severe overheating, and accelerated wire fatigue of the wire saw, thus greatly improving the stability and efficiency of wire saw cutting.

[0017] Second, by controlling the extension and retraction of the telescopic cylinder, the tilt angle of the roller frame can be controlled. By setting the telescopic cylinder at the four corners of the roller frame, better support can be provided to the roller frame, making the roller frame more stable during operation. The telescopic cylinder is a hydraulic cylinder, which has the advantages of good load resistance and smooth and impact-free movement, further improving the stability of wire saw cutting.

[0018] Third, the roller seat is detachably installed on the roller frame, which allows operators to easily disassemble the roller roller and the roller seat for maintenance and replacement.

[0019] Compared with the prior art, the present invention provides a roller wire saw with adjustable cutting direction. By rotatably mounting the roller frame on the base, the cutting direction can be adjusted during cutting, reducing the area of ​​direct contact between the cutting line and the stone, and improving the stability and efficiency of cutting.

Through the cooperation of rotating shafts 12 and rotating seats 51, the roller frame 1 can rotate relative to the base 5 at a certain angle. In this way, when the stone 1000 is lifted for cutting, the operator can rotate the roller frame 1 to adjust the appropriate cutting direction. In addition, during the cutting process, the cutting angle can also be adjusted according to different working conditions, thereby reducing the contact area between the cutting line and the stone 1000. This can effectively avoid the problem of excessive contact length between the cutting line and the stone 1000, and avoid problems such as large tension fluctuations, severe heat generation, and accelerated wire fatigue of the wire saw, greatly improving the stability and efficiency of wire saw cutting.
