Description

Technical Field

[0001] The utility model relates to the field of saw blades, and more specifically, to a novel alloy saw blade. Background Art

[0002] Most steel and nonferrous metal processing companies use carbide-toothed circular saw blades to saw their products. At present, carbide-toothed circular saw blades have made great progress in processing technology, and their service life has also increased. However, in actual use, since the cutting machine installed with the circular saw blade is not always working, the circular saw blade is generally exposed when the cutting machine is not working. Since the outer edge of the circular saw blade is relatively sharp, the exposed circular saw blade is easy to accidentally injure the human body, posing a safety hazard.

[0003] In order to solve the above problems, a Chinese patent with publication number CN216263870U discloses a carbide tooth circular saw blade, which includes a circular saw blade body, and an external protective structure is provided on both sides of the circular saw blade body. The external protective structure includes a first protective plate and a second protective plate attached to the outer surfaces of both sides of the circular saw blade body, and the first protective plate, the circular saw blade body and the second protective plate are respectively provided with a first connecting hole, a second connecting hole and a third connecting hole of the same size and position on the left and right sides, and bolts are passed through the first connecting hole, the second connecting hole and the third connecting hole in turn, and the outer surface of the bolt is screwed and connected with a nut, and the inner side of the nut is in tight contact with the outer side of the second protective plate. The utility model provides an external protective structure on both sides of the circular saw blade body, and the protective effect of the external protective structure can make the circular saw blade body have a good protection in the non-working state, thereby effectively avoiding the accidental injury to human body parts caused by the exposed circular saw blade body, and the safety is greatly improved.

[0004] However, the disassembly and assembly of the two protective plates in the above solution is rather complicated, and workers need to spend a lot of time to install or disassemble the two protective plates. It is not convenient to use and has poor practicality.

[0005] Based on the above, the purpose of the present invention is to provide a new alloy saw blade to solve the above problems. Utility Model Content

The user can drive all the protective cover plates to flip toward the saw blade body through the flipping mechanism. After all the protective cover plates are flipped and closed, they can form a circular ring shape and cover the saw teeth on the saw blade body to prevent the saw blade from accidentally injuring workers when not in use.

[0008] By adopting the above technical solution, when the saw blade is not needed, the user moves the protective plate close to the saw blade body until the connecting rod is inserted into the corresponding connecting hole and the protective plate is fit with the saw blade body. Then the user drives all the protective cover plates to flip toward the saw blade body through the flipping mechanism. After all the protective cover plates are flipped and closed, they can form a ring shape and cover the saw teeth on the saw blade body, preventing the saw blade from accidentally injuring workers when not in use.

[0009] The utility model is further configured as follows: the flipping mechanism includes a connecting shaft with one end fixedly connected to the protective cover plate, the other end of the connecting shaft is rotatably connected to a connecting rod, the end of the connecting rod away from the connecting shaft is rotatably connected to a push rod, and a driving component is provided on the protective plate for simultaneously driving all push rods to move.

[0011] The utility model is further configured as follows: an anti-interference through hole is provided on the driving part.

[0012] The utility model is further configured as follows: rubber pads are arranged on both inner and outer sides of the protective cover plate.

[0013] In summary, the utility model has the following beneficial effects:

[0014] The utility model sets a rotating shaft hole on the saw blade body to connect with relevant equipment, sets a connecting hole and sets a connecting rod on the protective disk to make the two plug into each other, and then rotatably connects a plurality of protective cover plates and a flipping mechanism for driving the protective cover plates to flip and close. The user can drive the driving block to move along the trajectory of the sliding groove by rotating the driving part, and then the driving block drives the protective cover plates to flip through the push rod, the connecting rod and the connecting shaft in sequence. After all the protective cover plates are flipped and closed, they can form a circular ring shape and cover the saw teeth on the saw blade body, so as to prevent the saw blade from accidentally injuring workers when not in use. The installation of the protective disk is more convenient and more practical. BRIEF DESCRIPTION OF THE DRAWINGS
