Description

Technical Field

[0001] The utility model relates to the technical field of diamond saw blades, in particular to a diamond saw blade. Background Art

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting; high-speed steel saw blades for metal cutting (without carbide tips); carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel, etc.

[0003] Diamond saw blade is a cutting tool, widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. Diamond saw blade mainly consists of two parts: matrix and cutter head. The matrix is ​​the main supporting part of the bonded cutter head, while the cutter head is the cutting part during use. The cutter head will be continuously consumed during use, while the matrix will not. The reason why the cutter head can play the role of cutting is that it contains diamond. Diamond is the hardest substance at present. It rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head. During use, the metal matrix is ​​consumed together with the diamond. Generally, in the ideal situation, the metal matrix is ​​consumed faster than the diamond, which can ensure the sharpness of the cutter head and ensure that the cutter head has a longer life.

[0004] In the process of cutting stone, diamond saw blades will be subjected to alternating loads such as centrifugal force, sawing force, and sawing heat, which will cause wear and tear of diamond saw blades due to force effect and temperature effect. Force effect: In the sawing process, the saw blade is subjected to axial force and tangential force. Due to the force in the circumferential direction and radial direction, the saw blade is wavy in the axial direction and disc-shaped in the radial direction. Both of these deformations will cause uneven rock cut surface, much stone waste, loud noise and increased vibration during sawing, resulting in early damage to diamond segments and reduced saw blade life. Temperature effect: The influence of temperature on the saw blade process is mainly manifested in two aspects: one is the graphitization of diamonds in the segments; the other is the thermal stress between diamonds and the matrix, which causes the diamond particles to fall off prematurely.

[0005] For example: The Chinese utility model with application number: 202320019589.4 is a diamond saw blade, which includes a substrate, a cutter head is fixedly connected to the outer surface of the substrate, a groove is provided on the outer surface of the substrate, a protective layer is fixedly connected to the inner wall of the groove, a wear-resistant layer is fixedly connected to the outer surface of the substrate, a mounting hole is provided inside the substrate, and a reinforcement tube is fixedly connected to the inner wall of the mounting hole. The utility model has the following advantages and effects: the edge of the substrate is protected, the wear-resistant layer performs a large-area protective treatment on the substrate to improve the wear resistance of the substrate, thereby improving the service life of the substrate, the saw blade is installed with other equipment through the mounting hole, the connecting layer plays a connecting role, the anti-wear part is fixed, the anti-wear part improves the anti-wear effect of the mounting hole, and prevents the mounting hole from being worn and affecting the installation of the saw blade, so that the overall protection measures of the saw blade are stronger and the saw blade is more durable and wear-resistant.

[0006] Although the above device can play a protective and heat dissipation role at the edge of the substrate, the above device still needs to be improved during use.

[0007] 1. When cutting deeply, the debris will splash along the direction of the sawtooth rotation due to inertia. The baffle in the baffle assembly can prevent the debris from splashing around and discharge it in a fixed direction, reducing the debris from entering the air and causing damage to the workers.

[0008] 2. The heat dissipation method of the above device is to set a heat sink and a heat sink ring on the tool for heat dissipation. This heat dissipation method has a relatively good heat dissipation effect, but the above device is prone to wear and tear and is easily damaged. The method of replacing the heat sink and the heat sink ring for a long time is too costly, and the above method needs to be effectively improved. Utility Model Content

[0029] A material blocking assembly is installed on the support frame, and the material blocking assembly includes two fixing rings 2 connected to the support frame by bolts, and the two fixing rings 2 are fixedly connected to fixing bars 6, and the fixing bars 6 are fixedly connected to guide plates 3, and the two guide plates 3 are provided with sliding grooves on the opposite sides, and a blocking piece 7 is slidably connected in the sliding groove, and the inner ring of the fixing ring 2 is passed through by the output shaft of the electric motor, and the saw blade body 1 is located between the two fixing rings 2;

[0030] A protective piece is installed on the material blocking assembly.

[0031] In this embodiment, a heat dissipation component is provided on the saw blade body, which can cool the saw blade body rotating at high speed. A material blocking component is installed on the support frame. When the material is deeply cut, the generated debris can splash around along the direction of the saw teeth. The blocking plate in the material blocking assembly can prevent the debris from moving upward and can effectively block it from falling to the ground, thereby reducing the splashing of debris and preventing it from causing harm to the health of people around.

[0032] The protective member is a protective sleeve 4 which is detachably mounted on the material retaining assembly, and the protective sleeve 4 is mounted on the fixing bar 6 by means of bolts.

[0033] In this embodiment, when the protective cover is needed, it can be directly installed, and when it is not needed, it can be directly removed. At the same time, the installation of the protective cover can effectively protect the rotating saw blade body to avoid damage to external personnel or objects due to other reasons during rotation, thereby effectively protecting the outside.

[0034] The heat dissipation component includes a heat dissipation channel 8 opened on the saw blade body 1. The heat dissipation channel 8 is provided with a cooling liquid, and the cooling liquid is a coolant or a heat-conducting silicone oil.

[0035] In this embodiment, a heat dissipation channel is provided on the saw blade body, and coolant or heat-conducting silicone oil is added into the channel, which can effectively prolong the overheating time of the saw blade body.

[0036] The heat dissipation assembly further includes a heat dissipation hole 5 formed on the saw blade body 1 .

[0037] Specific usage of the device 1: When cutting the material in depth (for example, when cutting a tree with a radius greater than the width of the saw blade body into two pieces, when cutting to a certain depth, turn the motor or turn the tree to change its cutting position and continue cutting) when cutting a tree with a radius less than the width of the saw blade body into two pieces, you only need to cut directly. The specific cutting method is to hold the motor or support frame to make the saw blade body contact the material. The saw blade body can effectively cut the material. During cutting, a certain amount of debris will be generated. The debris moves along the movement direction of the saw blade body. The baffle in the material baffle assembly installed on the support frame will block the downward (upward) debris, and the upward debris will be ejected along the inclination direction of the baffle, which can effectively prevent the debris from being ejected upward.

[0038] Specific usage method 2 of the device: When cutting rectangular materials, fix the motor or support frame on the external construction table or place the material on the construction table. You only need to push the motor or the material to cut the material. The debris generated by the cutting will be blocked by the baffle, so that the debris will be ejected along the inclination angle of the baffle.
