Description

Technical Field

[0001] The utility model relates to the technical field of electronic saw blades, in particular to a novel tooth profile structure for cutting and processing electronic saw blades of panel furniture. Background Technique

[0002] The cutting electronic saw blade is widely used in our company. Comparing the two materials on the market, the diamond saw blade has a long service life but is not sharp, while the alloy saw blade is sharp but not durable. At present, in many classrooms, due to the loose problem of the board material, the diamond saw blade explodes at the edge during cutting. Many tooth profiles or numbers of teeth have been tried but failed, and alloy saw blades have to be used. Compared with diamond saw blades, the use cost of alloy saw blades is very high, increasing the cost of SBU. At present, the tooth profile of diamond saw blades has been solidified in textbooks for many years and there is no innovation.

[0003] However, in the existing woodworking field, especially in the process of sawing particleboard, the problem of edge bursting has always been a technical problem in the industry. Due to its special fiber structure and loose wood characteristics, particleboard is prone to uneven stress distribution during sawing, which in turn causes edge bursting. This not only affects the quality of the processed products, but also increases the production cost and rework rate. In view of this situation, although there are many types of existing saw blade tooth profiles on the market, including left and right teeth, tapered teeth, flat teeth, trapezoidal teeth, crescent teeth, etc., each tooth profile has certain limitations in dealing with the problem of easy edge bursting during particleboard sawing. The common practice is to use the main saw and the slot saw in combination to slow down the bursting phenomenon, but this method often requires additional adjustments to the equipment, increasing the complexity and cost of operation. Therefore, it is urgent to design a novel tooth profile structure for cutting and processing electronic saw blades of panel furniture to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel tooth profile structure for cutting and processing electronic saw blades of panel furniture, so as to solve the problem that in the existing woodworking field, especially in the process of sawing particleboard, the problem of edge bursting has always been a technical problem in the industry. Due to its special fiber structure and loose wood characteristics, particleboard is prone to uneven stress distribution during sawing, which in turn causes edge bursting. This not only affects the quality of the processed products, but also increases the production cost and rework rate. In view of this situation, although there are many types of existing saw blade tooth profiles on the market, including left and right teeth, tapered teeth, flat teeth, trapezoidal teeth, crescent teeth, etc., each tooth profile has certain limitations in dealing with the problem of easy edge bursting during particleboard sawing. The common practice is to use the main saw and the slot saw in combination to slow down the bursting phenomenon, but this method often requires additional adjustments to the equipment, increasing the complexity and cost of operation.

[0005] To achieve the above object, the present utility model provides the following technical solutions: a novel tooth profile structure for cutting and processing a saw blade of an electronic saw for panel furniture, including a saw blade body, side tooth racks are uniformly arranged on the side surface of the saw blade body, side tooth grooves are uniformly arranged on the side surface of the saw blade body through the side tooth racks, and a chip cutting edge is arranged at the corner of the side tooth rack;

[0006] A central disc, the central disc is movably connected inside the saw blade body, an inner seat is fixedly connected to the inner wall of the central disc, and a mounting core is arranged on the inner wall of the inner seat.

[0007] Preferably, reinforcing bars are uniformly arranged inside the inner seat.

[0008] Preferably, sealing rings are arranged at the upper and lower ends of the mounting core.

[0009] Preferably, a side connection groove is opened on the side surface of the central disc, and a clamping rack is arranged on the inner wall of the side connection groove.

[0010] Preferably, first sealing rings are arranged at the upper and lower ends of the clamping rack.

[0011] Preferably, a second sealing ring is arranged on the inner wall of the saw blade body.

[0012] Preferably, a saw blade alloy block is fixedly connected to one end of the chip cutting edge, and a reinforcing block is arranged at one end of the saw blade alloy block.

[0013] Preferably, the saw blade alloy block and the reinforcing block are adapted to the side tooth rack and the side tooth groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] For this novel tooth profile structure for cutting and processing a saw blade of an electronic saw for panel furniture, through the setting of the saw blade body, side tooth racks, side tooth grooves, chip cutting edges, saw blade alloy blocks and reinforcing blocks, first of all, the inclination angle of the chip cutting edge is one of the key factors to improve the cutting effect. Through reasonable inclination angle design, aspects such as cutting force, heat dissipation effect, and cutting surface quality during the cutting process can be optimized, thereby improving cutting efficiency and processing quality, reducing the edge breakage of the board, solving the shortcoming of poor sharpness of diamond, the chip cutting edge is inclined at a certain angle with the saw blade body, the side tooth racks and side tooth grooves of the saw blade body adopt left and right tooth profiles, which improves the chip cutting force on both sides of the board and is not prone to edge breakage. Currently, there is no angle-changing tooth profile in this regard for the tooth profiles of diamond saw blades. Different from the traditional tooth profile, the groove saw cooperation can be cancelled, and a single saw blade can achieve blanking. There is no even notch on the sawing section of the blanking board, which reflects the practicability of the equipment design.

[0016] The novel tooth profile structure for the cutting of saw blades of panel furniture electronic saws further improves the overall use effect of the equipment through the set saw blade body, center disc, inner seat, installation core, reinforcement strip, sealing ring, side connection groove, clamping rack, first sealing ring and second sealing ring. During daily use, the staff can perform a sealing and clamping operation on the center disc as a whole with the second sealing ring on the inner wall of the saw blade body through the clamping rack and the first sealing ring on the side, and then perform a reinforcement operation on the connection through the reinforcement strip and the sealing ring on the inner seat and the installation core on the inner wall of the center disc to ensure the firmness of the saw blade body as a whole during subsequent use, reflecting the comprehensiveness of the equipment design.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention:

[0024] A new tooth profile structure for the cutting of a panel furniture electronic saw blade, including a saw blade body 1. Side tooth racks 2 are evenly arranged on the side surface of the saw blade body 1. Side tooth grooves 3 are evenly arranged on the side surface of the saw blade body 1 through the side tooth racks 2. Chip edges 4 are arranged at the corners of the side tooth racks 2. A second sealing ring 13 is arranged on the inner wall of the saw blade body 1. One end of the chip edge 4 is fixedly connected to a saw blade alloy block 14. A reinforcing block 15 is arranged at one end of the saw blade alloy block 14. The saw blade alloy block 14 and the reinforcing block 15 are adapted to the side tooth racks 2 and the side tooth grooves 3. The angle is 45 degrees, which is the median value. This fully ensures the sharpness of the saw blade and also ensures that the material is not prone to chipping. Compared with the conventional rectangular teeth, the tooth surface cuts the chip perpendicular to the board surface. After being modified to 45 degrees, the diamond edge cuts the chip at a certain angle, increasing the sharpness of the tooth profile chip. This is the main design logic.

[0025] A central disc 5. The central disc 5 is movably connected inside the saw blade body 1. An inner seat 6 is fixedly connected to the inner wall of the central disc 5. An installation core 7 is arranged on the inner wall of the inner seat 6. Reinforcing strips 8 are evenly arranged inside the inner seat 6. Sealing rings 9 are arranged at the upper and lower ends of the installation core 7. A side connection groove 10 is opened on the side surface of the central disc 5. A clamping rack 11 is arranged on the inner wall of the side connection groove 10. First sealing rings 12 are arranged at the upper and lower ends of the clamping rack 11. The whole central disc 5 is hermetically clamped to the second sealing ring 13 on the inner wall of the saw blade body 1 through the clamping rack 11 and the first sealing ring 12 on the side surface. Then, the reinforcing strips 8 and the sealing rings 9 on the inner seat 6 and the installation core 7 on the inner wall of the central disc 5 are used to reinforce the connection part, ensuring the firmness of the whole saw blade body 1 during subsequent use.

[0026] Working principle: The cutting edge 4 is inclined and installed by means of the back saw blade alloy block 14 and the reinforcement block 15 in cooperation with the side tooth rack 2 and the side tooth groove 3 on the side of the saw blade body 1. The inclined cutting edge 4 can change the flow direction and speed of the chips generated during cutting. An appropriate inclination angle helps to guide the chips to be discharged more smoothly, reduce the accumulation of chips between the tool and the workpiece, thereby reducing the cutting resistance and cutting temperature, and improving the cutting efficiency. The inclination angle of the cutting edge 4 can affect the contact area between the tool and the workpiece during cutting and the distribution of the cutting force. A reasonable inclination angle can reduce the cutting force at the front end of the tool, make the cutting process more stable, reduce tool wear and workpiece deformation, and improve the machining accuracy. The inclined cutting edge 4 helps to form a larger heat dissipation area during cutting, enabling the heat generated by cutting to be dissipated to the surrounding environment more quickly. This helps to reduce the temperature in the cutting area, reduce tool thermal wear and workpiece thermal deformation, and improve the cutting stability and tool life. The inclined cutting edge can form a smoother cutting surface during cutting, reducing the generation of defects such as burrs and ripples. This is because the inclined cutting edge can distribute the cutting force more evenly, avoiding the decline in surface quality caused by local stress concentration. For materials with different hardness and toughness, the cutting effect can be optimized by adjusting the inclination angle of the cutting edge. Harder materials may require a larger inclination angle to reduce the cutting force and improve the heat dissipation effect, while softer materials... The above is all the working principle of the present utility model.
