Description

Technical Field

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

[0002] A diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stones, ceramics, etc. The diamond saw blade mainly consists of two parts: a matrix and a cutting head. The matrix is the main supporting part for bonding the cutting head, while the cutting head is the part that performs cutting during use. The cutting head will be continuously consumed during use, while the matrix will not. The reason why the cutting head can play a cutting role is that it contains diamond. As the hardest substance, diamond rubs and cuts the object to be processed in the cutting head. And the diamond particles are wrapped inside the cutting head by metal.

[0003] Currently, when a traditional combined diamond saw blade is in use, the saw blade is installed on a rotating shaft, and the motor drives the rotating shaft to rotate. The saw blade on the rotating shaft rotates to cut an object. However, when the saw blade is cutting, the cutting edge will be damaged to varying degrees, and even become unusable, affecting the cutting work. It is necessary to replace the entire new saw blade, resulting in a high replacement cost. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0020] (III) Beneficial Effects

[0021] The present utility model has the following beneficial effects compared with the prior art:

[0022] To solve the problem that in the traditional combined diamond saw blade, the cutting edge is damaged to varying degrees during cutting, and even cannot be used, affecting the cutting work, and the whole new saw blade needs to be replaced, resulting in a high replacement cost. The present utility model separates the saw disc from the saw blade by setting the saw disc, slot, first threaded hole, saw blade, inserting piece and second threaded hole. When an individual saw blade is damaged and cannot be used, by removing the bolt on the unusable saw blade and inserting the inserting piece of the new saw blade into the slot of the saw disc, the second threaded hole on the saw blade is opposite to the first threaded hole on the saw disc, and the bolt is tightened on the second threaded hole and the first threaded hole to complete the replacement. There is no need to replace the whole saw blade, and the replacement cost is low;

[0023] By setting the edge groove and the edge piece, the saw blades on the saw disk can be kept on the same plane, enabling more precise cutting of objects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] As Figures 1 - 3 shown, a combined diamond saw blade in this embodiment includes a saw disk 1. Slots 2 are provided on the peripheral wall of the saw disk 1. A baffle 3 is arranged between the slots 2. First threaded holes 4 are provided at the positions of the slots 2 on the saw disk 1. A saw blade 5 is inserted into the peripheral wall of the saw disk 1. The saw blade 5 is composed of an insert piece 6 and a blade 8. The insert piece 6 is located below the blade 8. Second threaded holes 7 are provided on the insert piece 6. A cutting edge 9 is provided on one side wall of the blade 8. A breaking edge 10 is provided on the other side wall of the blade 8. An edge groove 11 is provided at the bottom of the breaking edge 10. An edge piece 12 is fixed at the bottom of the cutting edge 9. A reinforcing edge 13 is installed on the surface of the blade 8 inside the cutting edge 9 and the breaking edge 10. A reinforcing plate 14 is installed on the surface of the saw disk 1. Third threaded holes 15 are provided in the reinforcing plate 14 on the saw disk 1. The slope of the side wall of the cutting edge 9 of the cutting edge is smaller, which is convenient for the cutting edge 9 to cut objects. The slope of the side wall of the breaking edge 10 of the breaking edge is larger, and the side of the breaking edge 10 is thicker, which is convenient for the cutting edge 9 to cut objects.

[0031] As Figures 1 - 3As shown, in this embodiment, the slot 2 is connected to the slot of the insert piece 6 in a card slot manner. Bolts are installed on the first threaded hole 4 and the second threaded hole 7. After the saw blade 5 is inserted into the slot 2 through the insert piece 6, the first threaded hole 4 and the second threaded hole 7 coincide, and the saw blade 5 is fixed to the saw disc 1 through the bolts. The surface of the bolt in the first threaded hole 4 is flush with the surface of the saw disc 1, and the surface of the reinforcement edge 13 is flush with the surface of the blade 8. When rotating, the bolt in the first threaded hole 4 and the reinforcement edge 13 will not affect the cutting of the device. The edge groove 11 is adapted to the edge piece 12, and the edge groove 11 is connected to the edge piece 12 in a card slot manner. Through the edge groove 11 and the edge piece 12, the saw blade 5 can be kept in the same plane. The insert piece 6 is welded to the blade 8, and the reinforcement edge 13 is welded to the blade 8, which can reinforce the saw blade 5 by the reinforcement edge 13. The saw disc 1 is of an annular structure, and the saw disc 1 is connected to the using device by bolts through the third threaded hole 15, which can fix the saw disc 1 to the using device through the third threaded hole 15. The reinforcement plate 14 is of an annular structure, and the reinforcement plate 14 is welded to the saw disc 1, which can reinforce the saw disc 1 by the reinforcement plate 14.

[0032] The specific implementation process of this embodiment is as follows: When in use, first insert the insert piece 6 on the saw blade 5 into the slot 2 of the saw disc 1. At this time, the second threaded hole 7 on the saw blade 5 coincides with the first threaded hole 4 on the saw disc 1, and the saw blade 5 is fixed to the saw disc 1 through bolts. The saw disc 1 is fixed to the motor of the using device through the third threaded hole 15, and the motor drives the saw disc 1 to rotate at a high speed to cut items. When an individual saw blade 5 is damaged and cannot be used, by removing the bolts on the unusable saw blade 5 and inserting the insert piece 6 of the new saw blade 5 into the slot 2 of the saw disc 1, the second threaded hole 7 on the saw blade 5 is opposite to the first threaded hole 4 on the saw disc 1, and bolts are tightened on the second threaded hole 7 and the first threaded hole 4 to complete the replacement. There is no need to replace the entire saw blade 5, and the replacement cost is small.
