Description

Technical Field

[0001] This invention relates to the field of cutting and processing technology, and more specifically, to a multi-wire cutting device with variable span. Background Technology

[0002] Multi-wire cutting of stone is a common processing method in the field of stone cutting. Currently, when multi-wire cutting equipment is used for stone cutting, the tension of the diamond wire will decrease with the increase of usage time. The traditional solution is to tighten the diamond wire at both ends, which will lead to uneven tension of the diamond wire and thus affect the processing.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Summary of the Invention

[0004] The present invention provides a multi-wire cutting device with variable span, which adjusts the tension by changing the span, aiming to improve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a variable span multi-wire cutting device, including a span adjustment mechanism and a cutting mechanism mounted on a frame. The cutting mechanism includes two sets of roller groups and diamond wire connected between the output ends of the two sets of roller groups. The two sets of roller groups are arranged vertically and parallel to each other on the frame, and the roller groups are slidably connected to the frame. Each roller group includes two roller assemblies symmetrically arranged on both sides of the span adjustment mechanism. Each roller assembly includes a mounting base and rollers rotatably connected to the mounting base. One end of each roller is connected to a first drive motor, and the other end extends outward from the frame and is connected to the... The diamond wire is connected; a lifting mechanism is provided below the diamond wire, which is used to support and move the cutting material so that the cutting material can be close to the diamond wire for cutting; the span adjustment mechanism includes a second drive motor, a screw, nut blocks, and a connecting frame. The screw is vertically arranged between two roller assemblies and is driven by the second drive motor; two nut blocks are connected to the screw, and the middle part of the connecting frame is hinged to the nut blocks, and both ends are hinged to the roller assemblies on both sides respectively. When the nut blocks move longitudinally on the screw, the connecting frame can drive the roller assemblies on both sides to move closer or further away. By adjusting the roller span of the cutting mechanism through the span adjustment mechanism, the tension of the diamond wire can be adjusted, making it evenly stressed, less prone to breakage, and highly efficient and flexible; in addition, when processing stones of different sizes, the optimal cutting width can be achieved by adjusting the span, improving cutting efficiency, reducing waste, and reducing pollution.

[0006] As a further optimization, a slide rail is provided laterally on the frame, and the roller assembly is slidably connected to the slide rail. This avoids self-locking due to friction during movement.

[0007] As a further optimization, the roller assembly is provided with a sliding seat, the mounting base and the first drive motor are mounted on the sliding seat, and the sliding seat is slidably connected to the slide rail; the connecting frame is hinged to the sliding seat.

[0008] As a further optimization, a bearing seat is provided on the sliding seat, and the connecting frame is connected to the sliding seat through the bearing seat. According to the principle of force transmission, there will be an upward support force at the connection between the connecting frame and the sliding seat. The bearing connection can ensure that the friction generated by the support force will not cause jamming.

[0009] As a further optimization, the second drive motor is installed on the lower side of the frame with its output end facing upward, and is connected to the screw drive via a coupling to drive the screw to rotate.

[0010] As a further optimization, a limit block is provided at the top of the screw to prevent the nut block from falling off.

[0011] As a further optimization, the roller is provided with multiple grooves for placing the diamond wires.

[0012] As a further optimization, the connecting frame includes two sets of hinged rods, which are hinged to both sides of the nut block. One end of each hinged rod is hinged to the nut block, and the other end is hinged to the roller assemblies on both sides.

[0013] As a further optimization, the upper and lower roller groups are aligned longitudinally.

[0014] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0015] This application provides a variable span multi-wire cutting device suitable for multi-wire cutting of large stone slabs. Firstly, it allows for tension adjustment. Traditional adjustment methods can only be performed from both sides of the diamond wire, resulting in uneven force distribution and poor performance. This invention adjusts the tension by changing the span, achieving uniform force distribution, high efficiency, and simple operation. The span is changed using a motor, screw, nut block, and connecting frame, effectively reducing costs and improving efficiency. Furthermore, by changing the span, it can adapt to processing stone of different sizes, improving work efficiency, simplifying the workflow, and preventing damage to the diamond wire. This invention is suitable for production scenarios requiring high-efficiency processing, making it easy to promote and apply. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Depend on Figures 1 to 4As shown, this embodiment of the invention provides a variable span multi-wire cutting device, including a span adjustment mechanism and a cutting mechanism mounted on a frame 1. The cutting mechanism includes two sets of roller groups 2 and diamond wire 3 connected between the output ends of the two sets of roller groups 2. The frame 1 is arranged in a double layer, and the two sets of roller groups 2 are arranged vertically and horizontally on the upper and lower layers of the frame 1. The roller groups 2 are slidably connected to the frame 1. The roller groups 2 include two sets of roller assemblies symmetrically arranged on both sides of the span adjustment mechanism. The roller assembly includes a mounting base 4 and rollers 5 rotatably connected to the mounting base 4. One end of the roller 5 is connected to a first drive motor 6 via a coupling, and the other end extends outward from the frame 1 and connects to the diamond wire 3. The connected diamond wire 3 is supported by four rollers 5 to form a diamond coil. The first drive motor 6 drives the rollers 5 to rotate, thereby driving the diamond wire 3 to cut. It is important to note that the upper and lower roller groups 2 are aligned longitudinally, so that when the span adjustment mechanism adjusts the span between the roller roller assemblies, the tension can be guaranteed and the diamond wire 3 is subjected to more even force.

[0024] A lifting mechanism 9 is provided below the diamond wire 3. The lifting mechanism 9 is used to carry and move the cutting material 12 so that the cutting material 12 can be close to the diamond wire 3 for cutting. The lifting mechanism 9 includes a table 10 and a cylinder 11. The cylinder 11 is installed on the bottom side of the table 10. The output end of the cylinder 11 passes through the table 10 and abuts against the cutting material 12. During cutting, the cylinder 11 lifts the cutting material 12 so that it is close to the diamond wire 3 for cutting.

[0025] Preferably, the span adjustment mechanism includes a second drive motor 13, a screw 14, nut blocks 15, and a connecting frame 16. The screw 14 is vertically arranged between the two roller assemblies and is connected to the second drive motor 13 for transmission. Two nut blocks 15 are connected to the screw 14. The middle part of the connecting frame 16 is hinged to the nut blocks 15, and both ends are hinged to the roller assemblies on both sides respectively. A lead screw structure is formed between the nut blocks 15 and the screw 14. The second drive motor 13 is installed on the lower side of the frame 1, with the output end facing upward, and is connected to the screw 14 for transmission through a coupling. When the second motor drives the screw 14 to rotate, the nut blocks 15 are limited by the rotation of the connecting frame 16. When the nut blocks 15 move longitudinally on the screw 14, the connecting frame 16 can drive the roller assemblies on both sides to move closer or further away, thereby adjusting the distance between the two sets of roller assemblies, and thus adjusting the span of the diamond wire 3, thereby realizing the adjustment of the tension of the diamond wire 3.

[0026] Furthermore, a limit block 17 is provided at the top of the screw 14. By setting the limit block 17, a limiting function can be achieved, thereby preventing the nut block 15 located at the high end from falling out of the screw 14.

[0027] Preferably, a slide rail 18 is laterally arranged on the frame 1, and the roller assembly is slidably connected to the slide rail 18. Further, the roller assembly is provided with a sliding seat 7, and the mounting base 4 and the first drive motor 6 are mounted on the sliding seat 7. The sliding seat 7 is slidably connected to the slide rail 18, thereby enabling the roller assembly to move left and right on the frame 1 to adjust its position. Simultaneously, the limiting function of the sliding seat 7 and the slide rail 18 ensures the stability and rigidity of the equipment during the cutting process. The connecting frame 16 is hinged to the sliding seat 7. When the second drive motor 13 drives the screw 14 to rotate, controlling the nut block 15 to move up and down, this ultimately translates into the left and right movement adjustment of the roller 5, thereby adjusting the tension of the diamond.

[0028] Preferably, the connecting frame 16 includes two sets of hinge rod assemblies 19, which are hinged to both sides of the nut block 15. One end of each hinge rod assembly 19 is hinged to the nut block 15, and the other end is hinged to the roller assemblies on both sides. In this embodiment, the nut block 15 has protruding shafts on both sides, and the two sets of hinge rod assemblies 19 are connected to these shafts. Various hinge methods exist, which will not be elaborated here. Furthermore, the sliding seat 7 is provided with a bearing seat 8. The other end of each hinge rod assembly 19 is connected to the sliding seat 7 through a bearing in the bearing seat 8, thus enabling the two ends to move the sliding seats 7 on both sides when the middle of the hinge rod assembly 19 moves with the nut block 15. The two sets of hinge rod assemblies 19 provide a relatively stable connection, ensuring stability during adjustment. It should be noted that each roller group 2 has two slide rails 18, and the sliding seats 7 corresponding to the two slide rails 18 are respectively set under the mounting base 4 and the first drive motor 6. The screw 14 passes through the two slide rails 18, and the mounting base 4 and the first drive motor 6 are fixedly connected.

[0029] Preferably, the roller 5 is provided with multiple grooves 20 for placing and connecting diamond wires 3. By providing multiple grooves 20, multiple diamond wires 3 can be placed, thereby achieving multi-wire cutting and improving cutting efficiency.

[0030] When the tension of the diamond wire 3 decreases during processing, the second drive motor 13 can be started to drive the screw 14 to rotate. The screw 14 rotates through the nut block 15 and drives the connecting frame 16, transmitting the motion to the slider seat. This ultimately drives the roller assembly to move left and right, changing the span and thus changing the tension of the diamond wire 3, making the wire mesh more uniformly stressed.

[0031] When cutting stones of different sizes, the optimal cutting distance can be achieved by changing the span, or by replacing the diamond wire 3 with different lengths, which can effectively control the wire mesh tension, improve cutting efficiency, ensure cutting results, and reduce cutting waste.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
