Description

A dual-station bridge-type cutting machine Technical Field

[0001] This utility model relates to the field of stone cutting technology, specifically to a dual-station bridge-type center cutting machine. Background Technology

[0002] Stone is widely used due to its natural uniqueness, but rough stone must be processed and refined by various stone processing machines before it can be used. Currently, because traditional stone cutting equipment can only cut stone in one direction, most stone processing enterprises in China are still in the stage of manual or semi-mechanized simple processing, with low automation and backward production capacity, which cannot meet the large demand for stone materials.

[0003] A stone cutting machine is a type of stone processing equipment, widely used for its ability to process wide-format stone. Existing stone cutting machines typically place the stone on a worktable, and a movable, feedable cutting mechanism on a crossbeam cuts the stone, performing only a single straight cut. Furthermore, traditional cutting machines have only one cutting station. To cut stone into rectangular slabs of varying lengths and widths, the gap between the saw blades needs to be adjusted after the first straight cut, and then the worktable needs to be rotated 90 degrees for a second straight cut. This process is not only cumbersome but also significantly reduces stone cutting efficiency.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

The top plate 442 is provided with a lifting cylinder 45, and the piston rod of the lifting cylinder 45 is connected to the translation frame 441. The lifting cylinder 45 can drive the top plate 442 and the bottom plate 443 to move up and down, thereby adjusting the cutting height of the saw blade 43. The lower end of the base plate 443 is provided with a spindle box, and the spindle 42 is rotatably connected to the inside of the spindle box through bearings.

[0028] Specifically, a second motor 46 is installed on the translation frame 441. The motor shaft of the second motor 46 is connected to a reduction gearbox. A first gear 461 is mounted on the output shaft of the reduction gearbox. A first rack 32 is horizontally arranged on the crossbeam 3. The first gear 461 and the first rack 32 mesh with each other. The second motor 46 drives the first gear 461 to rotate, thereby causing the translation frame 441 to move laterally relative to the crossbeam 3.

[0029] In this embodiment, the cutting frame also includes a face shield 446, which is connected to the top plate 442 and the bottom plate 443.

The lower end of the side frame 51 is slidably connected to the side support 2. Specifically, the side support 2 is provided with a longitudinal guide rail 21, and the side frame 51 is provided with a rotatably connected guide wheel 56. The guide wheel 56 and the longitudinal guide rail 21 roll together, making the sliding of the side frame 51 more stable. The side of the side frame 51 is fixedly connected to the crossbeam 3.

[0031] In this embodiment, the workbench 1 includes a base frame 11, a turntable frame 12, and a support frame 13. The turntable frame 12 is hinged to the base frame 11. A turntable shaft is mounted on the turntable frame 12, and its upper end is connected to the support frame 13. A rotary motor connected to the turntable shaft can be mounted on the turntable frame 12 to drive the support frame 13 to rotate. A lifting cylinder 14 is mounted on the side of the base frame 11 and is hinged to the base frame 11. The piston rod of the lifting cylinder 14 is hinged to the turntable frame 12. The piston rod of the lifting cylinder 14 can lift the turntable frame 12 and the support frame 13, causing them to tilt relative to the base frame 11. Several rollers 15 are mounted on the turntable frame 12. The rollers 15 are in rolling contact with the lower surface of the support frame 13, providing good support and making the rotation of the support frame 13 more stable.

[0032] The working principle of this utility model:

[0033] Before cutting, the spacing of the saw blades 43 on both sides of the cutting mechanism 4 is adjusted according to the required length and width of the stone slab. The lifting cylinder 14 drives the turntable frame 12 and the support frame 13 to tilt, facilitating the loading of large stone slabs. Afterwards, the support frame 13 returns to the horizontal position, and the stone is first cut in a straight line by the cutting mechanism 4 on one side. Then, the support frame 13 rotates 90 degrees, and the stone is cut in a straight line by the cutting mechanism 4 on the other side. Finally, the lifting cylinder 14 drives the turntable frame 12 and the support frame 13 to tilt, making it easier for workers to remove the cut stone slab.

[0034] Compared with existing technologies, the beneficial effects are:

[0035] 1. This utility model is equipped with two cutting mechanisms 4, and the two cutting mechanisms 4 can be set with different saw blade 43 spacings, so that the two cutting mechanisms 4 on both sides have different cutting sizes. This utility model, through the dual-station cutting mechanism 4, can continuously cut stone into rectangular stone slabs of different lengths and widths. There is no need to adjust the saw blade 43 spacing during the cutting process, which simplifies the process and greatly improves the stone cutting efficiency.

[0036] In this invention, the turntable frame 12 can be supported by the lifting cylinder 14, causing the turntable frame 12 and the support frame 13 to tilt relative to the base frame 11. When the support frame 13 is tilted, workers can first lean large stones against the support frame 13, and then slowly drive the support frame 13 back to a horizontal state, making stone loading more convenient and safer. When unloading, the support frame 13 can also be tilted to facilitate the downward sliding of the cut stone slabs.

[0037] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
