Description

Technical Field

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

[0002] Cutting is often required during the processing of ceramics, and various types of cutting saw blades are used in this process, among which bevel saw blades can quickly cut ceramic materials at an angle. According to the prior art, such as the rock slab and ceramic bevel saw blade described in Chinese patent document CN202121835305.6, the disclosed technical solution can introduce water into the inner matrix, corrugated teeth, flat teeth, and the contact surface between the rock slab and the ceramic through the oblique flow groove, thereby achieving the purpose of directly cooling the friction part, and the premature loss of water can be avoided under the action of the direct current groove to ensure that the water can absorb more heat, thereby achieving the purpose of rapid cooling.

[0003] According to the technical solution disclosed by the invention, even if the saw blade in the prior art guides the water flow through the oblique flow groove, since the saw blade is in a state of high-speed rotation, most of the water will be quickly thrown out to the side after entering the oblique flow groove, resulting in a small amount of liquid actually used to provide heat dissipation effect for the sawing contact surface. The structure is limited by the rotation effect and cannot provide a higher heat dissipation effect. On the other hand, the thickness of the incision produced by the bevel saw blade during sawing will be affected by the thickness of the saw blade itself, and the sawing requirements of various incision widths can only be achieved by replacing the saw blade or sawing multiple times, which increases the cost of consumables or time. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a ceramic miter saw blade to solve the problems raised in the above-mentioned background technology. The present invention further improves the utilization effect of the coolant and can flexibly control the incision width produced by a single sawing.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a ceramic miter saw blade, comprising a miter saw blade body 1, a main cutting head 2 and an auxiliary cutting head 3, the miter saw blade body 1 comprising a guide groove 4, the side of the saw blade body 1 is provided with a guide groove 4, the main cutting head 2 is installed at the edge of the saw blade body 1, the surface of the main cutting head 2 is interspersed with a second locking bolt 7, and the main cutting head 2 is partially fixedly connected with the auxiliary cutting head 3 by using the second locking bolt 7, the surface of the saw blade body 1 is interspersed with a first locking bolt 8, and the saw blade body 1 is connected to an external power device by using the first locking bolt 8. When the ceramic miter saw blade is used, the main cutting head 2 and the saw blade body 1 are always fixed as a whole, and the number of auxiliary cutting heads 3 is increased according to the width of the ceramic surface to be sawed. After completing the connection between the main cutting head 2 and the auxiliary cutting head 3, the entire saw blade body 1 can be fixedly installed on an external driving device using the first locking bolt 8, and then it can be used for sawing.

[0024] In this embodiment, a water inlet groove 9 is provided on one side of the middle of the saw blade body 1, and the guide groove 4 is provided on the side of the water inlet groove 9. The guide groove 4 includes an inner heat dissipation arc groove 12 and an outer heat dissipation arc groove 13. A cone plate 10 is provided inside the water inlet groove 9. A diffusion channel 11 is provided between the water inlet groove 9 and the inner heat dissipation arc groove 12 and between the inner heat dissipation arc groove 12 and the outer heat dissipation arc groove 13. A drainage groove 14 is provided on the inner wall of the outer heat dissipation arc groove 13. A drainage port 5 is provided on the surface of the saw blade body 1. The drainage port 5 is provided at the end of the drainage groove 14. The inner walls of the inner heat dissipation arc groove 12 and the outer heat dissipation arc groove 13 are both provided with a concave structure. The guide groove 4 is provided on the surface, and the coolant can be temporarily stored in the arc groove through the guide groove 4, and part of the coolant can directly contact the ceramic sawing surface during the rotation of the saw blade, thereby increasing the heat dissipation effect and improving the utilization rate of the coolant.

[0025] Specifically, when in use, after the external coolant is sprayed into the water inlet groove 9 in a vertical state, it can impact the surface of the cone plate 10, and diffuse toward the side along the cone plate 10, and then enter the inside of the diffusion channel 11, and enter the inside of the inner heat dissipation arc groove 12 and the outer heat dissipation arc groove 13 in the diffusion channel 11 in turn, and accumulate briefly in the inner heat dissipation arc groove 12 and the outer heat dissipation arc groove 13, and finally directly perform heat dissipation treatment on the contact surface on the ceramic saw cut surface.

[0026] Since a large amount of coolant flows along the guide groove 4 and the coolant directly adheres to the contact surface, a large amount of dust generated when sawing ceramics can be more comprehensively washed by the coolant and thrown out in the direction in which the coolant is sprayed, thereby improving the dust treatment effect. The dust generated during the sawing process will be mixed with the inner heat dissipation arc groove 12 and the outer heat dissipation arc groove 13 due to the above-mentioned coolant. Therefore, when the subsequent coolant is discharged outward along the drainage groove 14, a large amount of dust can be directly discharged outward.

[0027] In this embodiment, the main blade head 2 is fixedly mounted on the side of the saw blade body 1, and the main blade head 2 includes a first steel ring 6 and fixed serrations 15, the fixed serrations 15 are arranged on the side of the first steel ring 6, the first locking bolts 8 pass through the surface of the first steel ring 6, and four first locking bolts 8 are arranged. Specifically, when the auxiliary blade head 3 is used, the auxiliary blade head 3 is directly fitted with the steel ring part of the main blade head 2, and then the second locking bolt 7 is passed through the inside of one of the positioning screw holes. The main blade head 2 and the auxiliary blade head 3 can be fixed as a whole, and the widening control effect of the serration part can be achieved.

[0028] In this embodiment, the auxiliary blade head 3 includes a second steel ring 16 and additional saw teeth 19. The additional saw teeth 19 are arranged on the side of the second steel ring 16. The surface of the second steel ring 16 is provided with a first positioning screw hole 17 and a second positioning screw hole 18. The main blade head 2 and the auxiliary blade head 3 are connected and fixed by using a second locking bolt 7 to pass through the first positioning screw hole 17 or the second positioning screw hole 18. The main blade head 2 is installed at the edge, and the main blade head 2 can be connected to the auxiliary blade head 3 part by the second locking bolt 7. Therefore, the thickness of the saw blade can be controlled, and the number of auxiliary blade heads 3 added can be controlled according to the specific cutting width required. At the same time, the staggered state of the saw teeth between different blade heads can be controlled by selecting different positioning screw holes.

[0029] Specifically, since the first positioning screw hole 17 and the second positioning screw hole 18 are provided, and the spacing between the first positioning screw hole 17 and the second positioning screw hole 18 is set to half of the spacing between two adjacent serrations, in this embodiment, after the second locking bolt 7 is connected to the first positioning screw hole 17, the fixed serrations 15 and the supplementary serrations 19 are completely aligned, and when the second locking bolt 7 is connected to the second positioning screw hole 18, the fixed serrations 15 and the supplementary serrations 19 are staggered with each other.
