Description

Technical Field

[0001] The utility model belongs to the technical field related to sawing tools, and in particular relates to a new type of saw blade that is energy-saving and has a long cutting life. Background Art

[0002] In traditional sawing tool technology, the design of saw teeth usually focuses on how to improve cutting efficiency and maintain the sharpness of the saw teeth. However, these tools often ignore the impact of repeated shear forces on the structural integrity of the saw teeth during long-term use, causing premature wear or breakage of the saw teeth. In addition, the high temperatures generated during the cutting process will further accelerate the wear of the saw teeth, so the service life of traditional saw blades is usually limited.

[0003] Existing technologies also do not adequately address the problem of unbalanced shear forces on saw teeth during operation. When cutting, saw teeth encounter materials of different hardness and density, which causes different degrees of shear forces on the saw teeth, thus accelerating the wear and damage of the saw teeth. Moreover, the traditional saw tooth design lacks an effective cooling system and cannot dissipate heat in time during the cutting process, exacerbating the wear problem of the saw teeth.

[0004] In view of the shortcomings of the existing technology, the market urgently needs a new type of saw blade, which can not only provide efficient cutting ability, but also significantly extend the service life of the saw teeth. In addition, the new saw blade design should also consider how to reduce the labor intensity of the user during operation and provide a safer and more comfortable use experience.

[0005] Therefore, the purpose of the present invention is to provide a new type of energy-saving and ultra-long cutting life saw blade, which overcomes the above technical difficulties through a series of innovative designs. The saw blade adopts key technologies such as a unique combination of saw teeth and buffer mechanism, a built-in coolant system, and an automatic force feedback mechanism to achieve the comprehensive effect of improving cutting efficiency, extending service life, reducing labor intensity and improving safety. Through these improvements, the present invention aims to meet the market demand for high-efficiency and high-durability sawing tools. Utility Model Content

[0006] The utility model aims to provide a new type of saw blade with energy saving and ultra-long cutting life, so as to solve the problem that the existing saw blade proposed in the above background technology is repeatedly subjected to shear force, destroying its structural integrity and causing premature wear or breakage of the saw teeth.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of energy-saving saw blade with an ultra-long cutting life, comprising a saw disk, a plurality of saw teeth fixedly connected to the outer edge of the saw disk, a buffer hole passing through the interior of the saw disk from front to back, a front fixed plate is provided at the front end of the buffer hole, and the front fixed plate is attached to the outer wall at the center of the front end of the saw disk, a buffer shaft is fixedly connected to the center at the rear end of the front fixed plate, and the buffer shaft can rotate inside the buffer hole and fit with the inner wall of the buffer hole, and the rear end of the buffer shaft is fixedly connected to a rear fixed plate by bolts, and the rear fixed plate is attached to the outer wall at the center of the rear end of the saw disk.

[0008] Preferably, a plurality of buffer connecting rods are fixedly connected to the inner wall of the buffer hole, and a buffer stopper is fixedly connected to the other end of each of the plurality of buffer connecting rods.

[0009] Preferably, a plurality of buffer limit grooves and a plurality of energy absorption grooves are provided inside the outer edge of the buffer shaft, and the plurality of buffer limit grooves are respectively connected to the plurality of energy absorption grooves.

[0010] Preferably, the buffer connecting rod is elastically connected to the inside of the buffer limiting groove through the buffer stop head, and the buffer connecting rod can rotate and slide inside the buffer limiting groove around the front and rear center axis of the buffer shaft.

[0011] Preferably, the buffer stopper is elastically connected to the inside of the energy absorption groove through an energy absorption spring, and the buffer stopper can rotate and slide inside the buffer limit groove around the front and rear center axis of the buffer shaft inside the energy absorption groove.

[0012] Preferably, the front fixing plate, the buffer shaft and the center of the rear fixing plate are all penetrated by connecting holes and multiple fixing holes from front to back, and the connecting holes and the multiple fixing holes can be customized according to the connection characteristics of the equipment.

[0013] Preferably, a plurality of mutually connected oblique grooves and a plurality of straight grooves are provided at the inner center of the saw disk, and cooling liquid is provided inside the plurality of oblique grooves and the plurality of straight grooves, and the plurality of oblique grooves are arranged in an arc shape.

[0014] Preferably, the plurality of oblique grooves and the plurality of straight grooves are evenly and alternately distributed inside the saw disk around the front-rear center axis of the saw disk and are located between the saw teeth and the buffer holes, and the plurality of straight grooves are perpendicular to the front-rear center axis of the saw disk.

[0015] Compared with the prior art, the utility model provides a new type of saw blade with energy saving and ultra-long cutting life, which has the following beneficial effects:

[0016] 1. The saw disc is connected to a buffer mechanism through the internal buffer hole. The buffer mechanism usually includes a buffer shaft and multiple buffer connecting rods and buffer stops connected thereto to reduce the direct impact on the saw disc body. When the saw disc is subjected to shear force, the buffer connecting rod and buffer stop will move slightly in the buffer limit groove and absorb the impact force through the compression of the energy-absorbing spring.

[0017] 2. There are multiple oblique grooves and straight grooves inside the saw disc, which are used to guide the coolant to flow through the edge and center of the saw disc. The alternating arrangement of oblique grooves and straight grooves ensures that the coolant can evenly cover the entire surface of the saw disc, effectively taking away heat, preventing the saw disc and saw teeth from overheating, and at the same time reducing the temperature difference between various parts of the saw disc and reducing the stress caused by the temperature difference.

[0018] 3. The front fixing plate, buffer shaft and rear fixing plate are all equipped with connection holes and fixing holes in the center. They are not only used to fix the saw blade on the equipment, but also allow the saw blade to be customized and installed according to the needs of different equipment. This flexibility increases the application range of the saw blade. The design of the entire saw blade takes into account many factors such as mechanics, thermodynamics and fluid dynamics. Through a reasonable structural layout, the lightweight characteristics of the saw blade are achieved, while reducing the difficulty of maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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.

[0026] The utility model provides Figure 1 and Figure 2 The shown new type of energy-saving saw blade with ultra-long cutting life is characterized in that it includes a saw disk 1, a plurality of saw teeth 2 are fixedly connected to the outer edge of the saw disk 1, the saw disk 1 performs sawing by means of the saw teeth 2, a buffer hole 3 is penetrated through the front and rear of the saw disk 1, which is used for fixing and buffering the saw disk 1, a front fixing plate 4 is arranged at the front end of the buffer hole 3, and the front fixing plate 4 is attached to the outer wall at the center of the front end of the saw disk 1, which is used for fixing the front end of the saw disk 1, a buffer shaft 5 is fixedly connected to the center at the rear end of the front fixing plate 4, and the buffer shaft 5 can rotate inside the buffer hole 3 and fit with the inner wall of the buffer hole 3, the buffer shaft 5 is used to connect the front fixing plate 4 and the rear fixing plate 6, which can buffer the shear force exerted on the saw disk 1 by rotating inside the buffer hole 3, the rear end of the buffer shaft 5 is fixedly connected to the rear fixing plate 6 by bolts, and the rear fixing plate 6 is attached to the outer wall at the center of the rear end of the saw disk 1, which is used for fixing the rear end of the saw disk 1.

[0027] Preferably, the saw blade 1 is fixed to the equipment by the front fixing plate 4, the buffer shaft 5 and the rear fixing plate 6. When the equipment is running, the equipment will generate a shear force on the saw blade 1 when accelerating the saw blade 1. At the same time, when sawing, the resistance of the saw blade 1 will change due to the difference between the sawing depth of the saw blade 1 and the internal density of the object sawed by the saw blade 1. When the resistance changes, the object and the equipment will simultaneously generate a large shear force on the saw blade 1. At this time, the buffer shaft 5 can rotate inside the saw blade 1 through the buffer hole 3 and buffer the shear force on the saw blade 1, thereby reducing the shear force on the saw blade 1, effectively protecting the saw blade 1 and preventing the saw blade 1 from being damaged, thereby extending the service life of the saw blade 1 and enabling the saw blade 1 to operate more stably.

[0028] like Figure 3 and Figure 4A plurality of buffer connecting rods 7 are fixedly connected to the inner wall of the buffer hole 3, which are used for buffering the shear force exerted on the saw disk 1 and limiting the position of the saw disk 1. The other ends of the plurality of buffer connecting rods 7 are fixedly connected to buffer stop heads 8, which are used for elastic connection of the buffer connecting rods 7. A plurality of buffer limit grooves 9 and a plurality of energy absorption grooves 10 are provided inside the outer edge of the buffer shaft 5, and the plurality of buffer limit grooves 9 are respectively connected to the plurality of energy absorption grooves 10, which are used for buffering sliding of the buffer connecting rods 7 and the buffer stop heads 8. The buffer connecting rods 7 are elastically connected to the buffer limit grooves 9 through the buffer stop heads 8, and the buffer connecting rods 7 can rotate and slide inside the buffer limit grooves 9 around the front and rear center axes of the buffer shaft 5. The buffer stop head 8 is elastically connected to the energy absorption groove 10 through an energy absorption spring 11, and the buffer stop head 8 can rotate and slide in the buffer limit groove 9 around the front and rear center axis of the buffer shaft 5 in the energy absorption groove 10. The buffer connecting rod 7 and the buffer stop head 8 slide in the buffer limit groove 9 and the energy absorption groove 10, and buffer the shear force exerted on the saw disk 1 through the compression of the energy absorption spring 11. The front fixed plate 4, the buffer shaft 5 and the rear fixed plate 6 are all penetrated by a connecting hole 12 and a plurality of fixing holes in the center front and back, and the connecting hole 12 and the plurality of fixing holes can be customized according to the connection characteristics of the equipment, and are used for fixing the saw blade to the equipment, and can be installed on equipment of different specifications for use.

[0029] Preferably, when the resistance experienced by the saw blade 1 changes, the rotation speed of the saw blade 1 will decrease instantaneously, causing the equipment and objects to simultaneously generate a large shear force on the saw blade 1. At this time, the saw blade 1 can slide in the buffer limit groove 9 and the energy absorption groove 10 through the buffer connecting rod 7 and the buffer stop head 8, and will compress the energy absorption spring 11. At the same time, the saw blade 1 will slightly rotate outside the buffer shaft 5 and between the front fixed plate 4 and the rear fixed plate 6, thereby converting the shear force energy experienced by the saw blade 1 into the energy absorption spring 11, reducing the shear force damage experienced by the saw blade 1 and avoiding damage to the saw blade 1. After the rotation speed of the saw blade 1 stabilizes, the energy absorption spring 11 will rebound to release the stored shear force energy.

[0030] like Figure 5 The saw disk 1 shown in the figure has a plurality of interconnected oblique grooves 13 and a plurality of straight grooves 14 in the inner center, and coolant is arranged inside the plurality of oblique grooves 13 and the plurality of straight grooves 14. The plurality of oblique grooves 13 are arranged in an arc shape, and are used for cooling the inner part of the outer edge of the saw disk 1. The plurality of oblique grooves 13 and the plurality of straight grooves 14 are evenly and alternately distributed inside the saw disk 1 around the front and rear center axis of the saw disk 1, and are located between the saw teeth 2 and the buffer holes 3. The oblique grooves 13 are used for guiding the coolant on the outer edge of the saw disk 1 back to the center of the saw disk 1, and the plurality of straight grooves 14 are perpendicular to the front and rear center axis of the saw disk 1, and the straight grooves 14 are used for transporting the coolant at the center of the saw disk 1 to the outer edge of the saw disk 1.

[0031] Preferably, a large amount of heat is generated due to friction during the sawing process of the saw disk 1. When the saw disk 1 rotates, the coolant in the arc-shaped inclined groove 13 is simultaneously subjected to centrifugal force and a pushing force toward the center of the saw disk 1 generated by the arc surface, while the coolant in the straight groove 14 is only subjected to the centrifugal force. Therefore, the inclined groove 13 will generate suction on the coolant in the straight groove 14 at the edge of the saw disk 1, and at the same time, the straight groove 14 will generate suction on the coolant in the inclined groove 13 at the center of the saw disk 1, so that the coolant can flow back from the inclined groove 13 to the center of the saw disk 1, and then flow to the edge of the saw disk 1 through the straight groove 14, so that the coolant can flow by itself in the multiple connected inclined grooves 13 and straight grooves 14 through the rotation of the saw disk 1, thereby bringing the heat generated by the edge of the saw disk 1 to the center of the saw disk 1 for cooling, and at the same time reducing the temperature difference between the center and the edge of the saw disk 1, which can not only cool the edge of the saw disk 1, but also reduce the stress caused by the temperature difference between various parts of the saw disk 1, thereby increasing the service life of the saw disk 1.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
