Description

Technical Field

[0001] The utility model relates to the technical field of numerical control sawing machines, in particular to a numerical control sawing machine with high working safety. Background Art

[0002] CNC sawing machines use circular saw blades, saw bands or saw blades as cutting tools to saw metal round materials, square materials, pipes and profiles. The processing accuracy of sawing machines is generally not very high. They are mostly used in material preparation workshops to cut various bars, pipes and other profiles. They are simple to operate, have high processing efficiency, and are convenient for batch sawing of workpieces. When cutting existing aluminum alloys, the hardness of aluminum alloys is relatively strong, and the band saw blades are easy to break. The fragments may burst to the side of the operator, causing damage to the operator. The safety performance is low and the use effect is poor.

[0003] In the prior art, an authorized patent with announcement number CN213729738U discloses a high-safety CNC sawing machine for the production of aluminum alloy extrusion devices, including a fuselage, guide columns are provided on both sides of the upper end of the fuselage, the guide columns, the upper end faces of the guide columns are fixedly connected to support plates, a saw beam is sleeved on the guide column, a band saw blade is movably connected to the lower end of the saw beam, leakage holes are evenly provided in the middle of the upper end face of the fuselage, a transmission device is provided in the middle of the front end face of the fuselage, and a protective plate is movably connected inside the transmission device to ensure that when in use, broken fragments of the band saw blade will be ejected toward the operator, effectively ensuring the safety of the operator and extending the service life of the band saw blade.

[0004] However, the above technical solution still has the following shortcomings when in use: the above-mentioned protective plate is arranged on the front side of the fuselage, and the protective plate is raised for protection when in use. However, when the CNC sawing machine is processing, when the sawing length is long, the front end of the material will hinder the raising of the protective plate, making the protective plate unusable. In this regard, we propose a CNC sawing machine with high working safety to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

This is the prior art and the specific structure is not recorded. Support seats 6 are fixedly welded on the opposite side walls of the two saw band mounting seats 4, a connecting block 7 is arranged on the supporting seat 6, a connecting assembly 8 is arranged on the connecting block 7, and a protective assembly 9 is arranged on the connecting assembly 8.

[0023] The support seat 6 is provided with a slide groove 10, and a slide rod 11 is fixedly welded in the slide groove 10. The connecting block 7 is slidably connected to the slide rod 11 through the provided through hole. The slide rod 11 is sleeved with an elastic spring 12, and the two ends of the elastic spring 12 are respectively fixedly connected to the top inner wall of the slide groove 10 and the connecting block 7. When the saw band mounting seat 4 drives the saw band 5 to move downward for sawing, the protective component 9 follows the movement and is pressed on the top wall of the material. As the saw band 5 moves downward for sawing, the protective component 9 is squeezed, driving the connecting block 7 to compress the elastic spring 12. The elastic force generated by the compressed elastic spring 12 can ensure that the protective component 9 is always pressed on the top wall of the material.

[0024] The connecting assembly 8 includes a connecting seat 13, which is fixedly welded on the connecting block 7. A mounting groove 14 is provided on the connecting seat 13. Two plug rods 15 are slidably connected to the front side wall of the connecting seat 13. A pull plate 16 is fixedly welded to the front ends of the two plug rods 15. Tension springs 17 are sleeved on the two plug rods 15. The two ends of the tension spring 17 are fixedly connected to the connecting seat 13 and the pull plate 16 respectively.

[0025] The protective component 9 includes a mounting frame 18, a pair of slots 19 are provided at both ends of the mounting frame 18, a transparent protective plate 20 is fixedly installed in the mounting frame 18, the mounting frame 18 is adapted to the mounting slot 14, and both ends of the mounting frame 18 are movably inserted in the two mounting slots 14 respectively, and the tension of the tension spring 17 acting on the pull plate 16 can keep the insertion rod 15 inserted into the slot 19, so that the mounting frame 18 is fixedly installed on the two connecting seats 13, which is convenient for the disassembly and assembly of the mounting frame 18 and the subsequent replacement of the transparent protective plate 20.

[0026] The two ends of the installation frame 18 are movably inserted into the two installation slots 14 respectively to prevent the installation frame 18 from shaking in the installation slots 14 and causing the transparent protective plate 20 to be unstable.

[0027] Working principle: When the utility model is in use, when the saw band mounting seat 4 drives the saw band 5 to move downward for sawing, it can drive the mounting frame 18 and the transparent protective plate 20 to move and press together on the top wall of the material. When the saw band mounting seat 4 drives the saw band 5 to continue sawing and moving downward, the connecting block 7 can slide on the supporting seat 6 to make the mounting frame 18 always press together on the top wall of the material for protection, and block the flying debris when the saw band 5 breaks, thereby improving the working safety of the CNC sawing machine. Due to the sliding cooperation between the connecting block 7 and the supporting seat 6, the mounting frame 18 can be suitable for CNC sawing machines to process materials of different diameters, thereby improving the applicability of CNC sawing machines. The two ends of the mounting frame 18 are respectively movably inserted in the two mounting grooves 14, and the tension of the tension spring 17 acting on the pull plate 16 can keep the insertion rod 15 inserted into the slot 19, so that the mounting frame 18 is fixedly installed on the two connecting seats 13, which is convenient for the disassembly and assembly of the mounting frame 18 and the subsequent replacement of the transparent protective plate 20.
