Description

Cutting device for diamond cutting blade

Technical Field

The utility model relates to the technical field of cutting, in particular to a cutting device for a diamond cutting blade.

Background Art

Diamond cutting is a cutting tool widely used in the processing of hard and brittle materials such as stone, concrete, prefabricated panels, new and old roads, ceramics, etc. The diamond cutting blade is mainly composed of two parts: a substrate and a cutter head. The substrate is the main supporting part of the bonded cutter head, and the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, while the substrate will not. The cutter head can play a cutting role because it contains diamonds. Diamond is currently the hardest substance. It rubs and cuts the object to be processed in the cutter head, and the diamond particles are wrapped in metal inside the cutter head. Diamond cutting blades cannot be used alone and are generally installed on cutting devices for use. After searching, the Chinese patent with publication number CN209453943U discloses a diamond cutting blade cutting machine. When it is used, the material to be cut is fixed on the workbench, the rotating assembly is started, and the rotating assembly The components drive the workbench to rotate, so that the material to be cut is rotated to the required cutting angle, and then the rotating component is stopped, and the pneumatic cylinder is started. The pneumatic cylinder drives the telescopic rod to extend, thereby driving the diamond cutting blade to move downward. When the diamond cutting blade moves to the required position, the pneumatic cylinder is stopped, and the driving motor is started. The driving motor drives the diamond cutting blade to rotate, thereby cutting the material to be cut; in this embodiment, the workbench is driven to rotate by the rotating motor, thereby driving the material to be cut on the workbench to rotate, and adjusting the cutting angle of the diamond cutting blade to the material to be cut, avoiding manual rotation of the material, improving work efficiency, reducing labor intensity, saving manpower, and improving cutting accuracy to meet different cutting requirements. However, during the cutting process, not only is it easy for debris to splash, but when the workpiece is moved during cutting, it is also easy to accidentally injure the operator's hand, and the safety is relatively low.

DETAILED DESCRIPTION

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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Example:

Please refer to Figures 1-4, a cutting device for a diamond cutting blade includes a supporting platform 1 and a diamond cutting blade 5. A cutting cover 4 with an opening facing downward is connected to the top of the supporting platform 1 through a lifting mechanism. The diamond cutting blade 5 is rotatably connected to the inner bottom of the cutting cover 4 and the bottom of the diamond cutting blade 5 protrudes from the bottom of the cutting cover 4. A telescopic shielding cover 16 is fixedly connected to the bottom of the cutting cover 4. The bottom of the telescopic shielding cover 16 is lower than the bottom end of the diamond cutting blade 5 in a free state. Both sides of the diamond cutting blade 5 are provided with chip suction covers 6 fixedly connected to the cutting cover 4. Both chip suction covers 6 are provided with chip suction spiral belts 8 fixedly connected to the diamond cutting blade 5, and the spiral directions of the two chip suction spiral belts 8 are set in opposite directions. The cutting cover 4 is also provided with a driving mechanism for driving the diamond cutting blade 5 to rotate and a debris collection and processing mechanism connected to the two chip suction covers 6.

Specifically, the debris collection and processing mechanism includes a chip box 9 fixedly mounted on the top of the cutting hood 4, a filter screen 10 fixedly mounted on the top of the chip box 9, and a chip collecting bucket 12 slidably matched with the bottom of the filter screen 10 is provided on the chip box 9 at the bottom of the filter screen 10. The two chip suction hoods 6 are sealed and fixed through the filter screen 10 and connected to the chip box 9 through a connecting pipe network 11. Due to the connection of the connecting pipe network 11, the debris exported from the two chip suction hoods 6 can be introduced into the chip box 9 from the top, and the gas goes out from the top through the filter screen 10. Due to the setting of the filter screen 10, the debris remains in the chip collecting bucket 12. Since the chip collecting bucket 12 is slidably matched with the bottom of the filter screen 10, when the chip collecting bucket 12 is pulled out of the chip box 9, the debris at the bottom of the filter screen 10 can be scraped off and enter the chip collecting bucket 12.

Specifically, the driving mechanism includes a driving motor 14, and both sides of the diamond cutting blade 5 are fixedly connected with the rotating shaft 7 for rotating the chip suction cover 6 on their respective sides, and the chip suction belts 8 on both sides are respectively fixedly installed on the rotating shaft 7 on the same side. The output shaft of the driving motor 14 is transmission-connected to one of the rotating shafts 7. Starting the driving motor 14 facilitates driving one of the rotating shafts 7 to rotate, thereby driving the diamond cutting blade 5 and the two chip suction belts 8 to rotate at the same time.

Specifically, the lifting mechanism includes a gantry 2 fixedly mounted on the supporting platform 1, a vertical driving cylinder 3 is vertically fixedly mounted on the gantry 2, the bottom of the vertical driving cylinder 3 is fixedly connected to the cutting hood 4, and the cutting hood 4 can be lifted and lowered by the vertical driving cylinder 3. Furthermore, a top plate 19 is fixedly mounted on the bottom output shaft of the vertical driving cylinder 3, and a plurality of fixed suspension rods 20 fixedly connected to the top plate 19 are arranged around the cutting hood 4. Through the cooperation of the top plate 19 and the plurality of fixed suspension rods 20, the vertical driving cylinder 3 and the cutting hood 4 can be connected conveniently. Furthermore, guide rods 21 that are vertically guided and slidably matched with the gantry 2 are arranged on both sides of the vertical driving cylinder 3, and the bottom of the guide rods 21 is fixedly connected to the top plate 19. Through the provision of the guide rods 21, the stability of the up and down movement of the top plate 19 can be increased, and the vertical driving cylinder 3 can be further protected to avoid the formation of a lateral shear force on the bottom of the vertical driving cylinder 3 during the cutting process.

Specifically, the drive motor 14 is hoisted on the chip collection box 9 through the mounting frame 13 and is located above the filter 10, and the output shaft of the drive motor 14 is connected to one of the rotating shafts 7 through a synchronous belt 15. The drive motor 14 is hoisted above the filter 10 to facilitate blowing and cooling the drive motor 14 when exhausting air from the filter 10. Although a certain amount of heat is generated during the cutting process, the heat is also blown to the drive motor 14 through the filter 10. However, when the wind blows on the drive motor 14, a part of the heat generated by the operation of the drive motor 14 will be blown away together, thereby achieving the situation of cooling and dissipating the heat of the drive motor 14. At the same time, after the cutting contact, all the heat can be blown away, thereby accelerating the cooling of the drive motor 14.

Specifically, the bottom of the telescopic shielding cover 16 is fixedly connected to a fixed bottom frame 17, and the top of the fixed bottom frame 17 is fixedly connected to a plurality of guide angle steels 18 that slide and cooperate with the cutting cover 4. The fixed bottom frame 17 facilitates the protection of the bottom of the telescopic shielding cover 16, and the cooperation of the plurality of guide angle steels 18 facilitates the limiting of the fixed bottom frame 17 and the telescopic shielding cover 16, so that the telescopic shielding cover 16 can only be extended and retracted up and down, thereby avoiding the lateral deformation of the telescopic shielding cover 16 due to the moving workpiece during the cutting process, thereby ensuring the sealing of the telescopic shielding cover 16 for the cut.

When in use, the workpiece to be cut is placed on the supporting platform 1, and the cutting cover 4 is lowered by the lifting mechanism until the diamond cutting blade 5 contacts the workpiece. When the diamond cutting blade 5 contacts the workpiece, the fixed bottom frame 17 contacts the workpiece first and compresses it accordingly, and the driving mechanism is started at the same time, thereby driving the diamond cutting blade 5 and the two chip suction belts 8 to rotate simultaneously, and the workpiece is cut by the diamond cutting blade 5. The debris generated by the cutting is covered by the cutting cover 4 and the telescopic shielding cover 16 to prevent splashing. At the same time, the two chip suction belts 8 attract the generated debris from both sides into the two chip suction covers 6 respectively, and arrange them side by side in the debris collection and processing mechanism for collection and processing, and at the same time, the workpiece is pushed horizontally along the cutting seam. At this time, due to the setting of the telescopic shielding cover 16, the hand can avoid touching the diamond cutting blade 5, further improving the safety performance. After cutting, the cutting cover 4 is reset by the lifting mechanism, and the cut workpiece can be taken down.
