Description

Technical Field

[0001] The utility model relates to the field of multi-rope saw machines, in particular to a combined rope saw machine for cutting thick plates with a simple structure. Background Art

[0002] When processing large stone slabs (height ≥ 1.5 meters, length ≥ 2 meters), the gang saw machine has the advantages of high efficiency, simple equipment operation, low production cost, high stone utilization rate, and less environmental pollution compared to traditional sand saws and circular saws. Multi-rope saw machines represent the development trend of large stone slab cutting and processing. However, the gang saw machine has a complex structure and high cost. It is mostly suitable for cutting large luxury stone slabs. It does not have a high cost-effectiveness for cutting low-value stones such as curbstones. When cutting stones of different slab thicknesses, the rope saw needs to be hung in different rope grooves to adjust the thickness size. It is inevitable that all the rope grooves are not in the same plane. When the rope grooves are not in the same plane, the rope saw will be agitated, thereby affecting the cutting quality of the slab.

[0003] The prior art CN200920019138.0 discloses a two-wheel multi-rope diamond bead saw, which includes five parts: a main motion mechanism, a feed mechanism, a guide mechanism, and a main frame. Feed pallets are installed on both sides of the main frame. The feed mechanism is installed on the upper end of the main frame, and the feed pallets on both sides are connected to the feed mechanism. The main motion mechanism includes a main motor and a driving wheel installed on one side of the feed pallet, and a telescopic hydraulic cylinder and a tensioning wheel installed on the other side of the feed pallet. The main motor is connected to the driving wheel through a transmission device, and the tensioning wheel is connected to the telescopic hydraulic cylinder. Guide wheels are installed on the feed pallets on both sides. The driving wheel, the tensioning wheel, and the guide wheel are all provided with more than two rope grooves, and the bead rope is wound in the rope groove. Although the utility model uses the feed pallet to tension the saw rope, the following problems still exist:

[0004] 1. When the wire saw needs to be adjusted to adapt to the cutting of stones of different thicknesses, since the rope grooves are distributed on different parts (such as the driving wheel, tensioning wheel and guide wheel), and these parts may have slight manufacturing tolerances or assembly errors, it is difficult for all rope grooves to maintain the same plane strictly. This will cause the wire saw to swing during work, which is the "stirring" you mentioned, which in turn affects the flatness and accuracy of the cutting surface, and may cause quality problems such as ripples on the cutting board surface and uneven saw marks.

[0005] 2. The utility model adopts a telescopic hydraulic cylinder and a tensioning wheel to tension the beaded rope. However, since the tensioning wheel is not only used to tension the beaded rope, but also acts as a force during cutting, the feed pallet is easy to loosen under long-term continuous operation, resulting in unstable tension of the saw rope, further affecting the cutting effect and the service life of the saw rope.

[0006] 3. The cutting spacing of existing gang saw machines is adjusted by hanging ropes between different wheel grooves. This adjustment method limits the thickness specifications of the board and can only cut thickness specifications that are integer multiples of the groove width. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a simple-structured combined wire saw machine for cutting thick plates. A mounting plate is used to connect and fix the transmission wheel and the tensioning wheel so that they can maintain synchronous adjustment. There is no independent tensioning device, and the cutting frame no longer requires a highly rigid connecting beam, which greatly reduces the weight of the lifting part and is more energy-efficient.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is a simple-structured combined wire saw for cutting thick plates, comprising: a portal frame, a lifting device, a cutting frame, a driven wheel, a tensioning wheel, and a driving wheel.

[0016] Preferably, the driving flywheel is arranged on the cutting frame via a spline shaft, one end of the spline shaft is drivingly connected to the driving device, and the other end is rotatably arranged on the cutting frame.

[0017] It should be noted that the driving flywheel is connected to the cutting frame through a spline shaft, and one end of the spline shaft is connected to the driving device for transmission, which not only obtains power, but also ensures that the driving flywheel and the spline shaft rotate synchronously. At the same time, the spacing between the driving flywheels can be adjusted along the axial direction of the spline shaft. The use of the spline shaft ensures the high efficiency and stability of power transmission, allowing the driving flywheel to rotate freely while bearing a large torque, thereby improving the working performance of the equipment, ensuring the stability of the rope saw rotation, and reducing the vibration and noise during the operation of the equipment.

[0018] Preferably, the lifting device includes a motor, a lead screw and a slider, the motor drives the lead screw to rotate, the slider and the lead screw thread are arranged on the portal frame, the cutting frame is fixedly arranged on the slider, and the lifting of the cutting frame is achieved by the motor drive.
