Description

Technical Field

[0001] The invention relates to a stone bearing device and a diamond wire stone cutting machine. Background Art

[0002] The cutting tools currently used to process stone rough materials into plates include saw blades, saw belts, and beaded wire saws. The cutting principle is to weld alloy diamond bits on saw blades and steel belts, or to string alloy diamond bits into wire saws. Traditional stone machines use the above cutting tools to process stone rough materials, such as bridge-type combined stone saws, marble frame saws, granite sand saws, multi-strand wire saws, band saw bisection machines, etc. Since the alloy diamond bits are large in size and need to be attached to the metal substrate, traditional cutting tools need to have a certain thickness to ensure normal cutting and cannot be thinned indefinitely. Therefore, when cutting stone, a saw seam of 3-10mm will be formed, causing waste and pollution of stone. This also makes traditional stone processing equipment have the disadvantages of large saw seams, high noise, large equipment footprint, high energy consumption, and high pollution.

[0003] To this end, in the Chinese patent application publication number CN 109866338 A, entitled "A New Stone Cutting Winding Device and Stone Cutting Saw Machine", a stone cutting saw machine is disclosed, comprising a new stone cutting winding device, a stone transfer vehicle, and a cutting transfer bracket, wherein the new stone cutting winding device is movably mounted on the cutting transfer bracket, or / and the stone transfer vehicle is movably arranged below the new stone cutting winding device; a passage is formed on the cutting transfer bracket for the stone transfer vehicle to move through, and the passage is located below the new stone cutting winding device; a plurality of groups of support rod assemblies are mounted on the stone transfer vehicle, which are vertically retractable and arranged along the moving direction of the stone transfer vehicle, and when the support rod assembly approaches the new stone cutting winding device, it moves downward to allow the stone transfer vehicle to pass through the passage below the new stone cutting winding device, and at the same time, the stone on it is cut by the wire net on the new stone cutting winding device. Among them, the new stone cutting winding device includes a mounting frame, a wire passing guide wheel, a first cutting guide wheel and a second cutting guide wheel. The two ends of the wire passing guide wheel, the first cutting guide wheel and the second cutting guide wheel are respectively rotatably connected to the mounting frame. The wire passing guide wheel, the first cutting guide wheel and the second cutting guide wheel are parallel and spaced apart. The first cutting guide wheel is arranged between the wire passing guide wheel and the second cutting guide wheel. The first cutting guide wheel and the second cutting guide wheel are respectively provided with a plurality of positioning parts for winding the diamond cutting wire to form a spaced parallel wire network.

[0004] During use, it was found that for a sawing machine with this structure, the diamond wire is set at an acute angle relative to the axis of the wire guide wheel. The layout accuracy of the diamond wire on the wire guide wheel is high, and debugging is more troublesome. Once the angle of the diamond wire at a certain position is unreasonable, during the sawing process, the diamond wire will axially cut the wire guide wheel, increase the walking resistance of the wire guide wheel, and even cut the wire guide wheel, causing wear of the wire guide wheel.

[0005] Furthermore, in the above-mentioned stone cutting saw machine, the stone transfer vehicle is equipped with multiple groups of support rod assemblies that are vertically retractable and arranged along the moving direction of the stone transfer vehicle. The stone is supported by the support rod assemblies, and the oil cylinders in the support rod assemblies are controlled to rise and fall successively, so that the stone transfer vehicle can avoid the diamond wire. When this stone transfer vehicle is in use, it is necessary to control the rise and fall of the oil cylinders at the same time during the sawing process, which is more troublesome to operate. In addition, when encountering short stones or uneven stone ground, when a part of the oil cylinders in the support rod assembly descends, the other part of the oil cylinders may be difficult to stably support the stone, or the support is unstable, resulting in relative movement of the stone, affecting the sawing of the stone.

[0074] In order to further explain the technical solution of the present invention, it is described in detail below in conjunction with embodiments.

[0075] Reference Figures 1 to 12 The present invention proposes a stone bearing device, including a bracket and a plurality of support plates 604 arranged on the bracket, a strip gap 605 for the diamond wire to travel is formed between adjacent support plates 604, one end of the support plate 604 is arranged on the bracket, and the other end is a free end, and also includes a supporting mechanism for supporting the free end, and the supporting mechanism is arranged corresponding to the free end in a manner that it can be moved away from the free end.

[0076] As a preferred embodiment of the present invention, the supporting mechanism includes a support plate 612 and a lifting mechanism for driving the support plate 612 to rise and fall. The support plate 612 is arranged below the free end, and the free end of the support plate 604 is supported by the support plate 612 to prevent the support plate 604 from deforming downward when subjected to force. The support plate 612 is arranged in the horizontal direction. As a preferred embodiment of the present invention, the lifting mechanism 611 is an oil cylinder. Of course, the lifting mechanism 611 in the present invention can also adopt other linear drive mechanisms such as cylinders and electric push rods.

[0077] As a preferred embodiment of the present invention, the bracket includes a first crossbeam 601, a second crossbeam 602 and a connecting crossbeam 603. The first crossbeam 601, the second crossbeam 602 and the connecting crossbeam 603 are all arranged in the horizontal direction and form a U-shaped frame. One end of the first crossbeam 601 is connected to one end of the connecting crossbeam 603, and one end of the second crossbeam 602 is connected to the other end of the connecting crossbeam 603. First pillars 609 are provided at both ends of the first crossbeam 601, and second pillars 610 are provided at both ends of the second crossbeam 602. The first pillars 609 and the second pillars 610 are both arranged in the vertical direction.

[0078] As a preferred embodiment of the present invention, a first card slot 606 is provided at the end of the first crossbeam 601, and a second card slot 607 is provided on the second crossbeam 602. The first card slot 606 and the second card slot 607 are both arranged in the horizontal direction. The supporting mechanism is a card plate 608 located below the free end of the support plate 612. One end of the card plate 608 is clamped in the first card slot 606, and the other end of the card plate 608 is clamped in the second card slot 607. The upper surface of the card plate 608 abuts against the lower surface of the support plate 604. With this structure, before the diamond wire enters the strip-shaped slit 605, the clamping plate 608 is removed from the first clamping groove 606 and the second clamping groove 607, thereby freeing up space for the diamond wire to enter. After the diamond wire (specifically the first mesh surface and the second mesh surface to be introduced below) enters the strip-shaped slit 605, the two ends of the clamping plate 608 are respectively clamped into the first clamping groove 606 and the second clamping groove 607, and the clamping plate 608 is used to support the free end of the support plate 604 to prevent the free end of the support plate 604 from being deformed downward by the gravity of the stone. When the stone is sawed, the clamping plate 608 is removed, so that the diamond wire exits the strip-shaped slit 605.

[0079] As a preferred embodiment of the present invention, the support plates 604 are arranged in parallel, and the width of the strip-shaped slits 605 is 2-3 mm.

Each mounting groove 613 is embedded with a support plate 604, and the side of the connecting crossbeam 603 close to the supporting mechanism is the first end face, and the opposite side is the second end face. The mounting groove 613 extends from the first end face to the second end face, and the two adjacent support plates 604 are set as a first support plate 6041 and a second support plate 6042. A first half thread groove is provided on the first support plate 6041. A second half thread groove is provided on the second support plate 6042, and also includes a locking screw 615. A plurality of locking screw grooves 614 are provided on the connecting crossbeam 603. The locking screw grooves 614 penetrate from the second end face to the mounting groove 613. Each locking screw groove 614 is arranged corresponding to two mounting grooves 613. The plurality of locking screw grooves 614 are arranged in two rows, upper and lower. The locking screw grooves 614 in the upper and lower rows are staggered. The locking screw grooves 614 are arranged corresponding to the first half thread groove and the second half thread groove. The locking screws 615 are screwed in the first half thread groove and the second half thread groove. With this structure, when the width of the support plate 604 is small (the width of the support plate 604 determines the distance between the two strip seams 605, that is, the width of the stone cutting), it is difficult to further fix the support plate 604 with screws. In the present invention, a half thread groove is opened on the first support plate 6041, and a half thread groove is opened on the second support plate 6042 to form a complete thread groove with the locking screw groove 614 on the connecting beam 603. The locking screw 615 is inserted into the locking screw groove 614 to further position the first support plate 6041 and the second support plate 6042 in the installation groove 613, thereby ensuring the stability of the strip seam 605.
