Description

Technical Field

[0001] This utility model relates to a circular saw blade, and more particularly to a circular saw blade with replaceable partial saw blades. Background Technology

[0002] Circular saw blades are a common sawing tool, widely used for cutting materials such as metal, wood, and plastic;

[0003] During the cutting process, the circular saw blade saws the surface of the object by using the teeth of the blade. When the circular saw blade cuts for a long time or cuts objects with different hardness, the teeth of the circular saw blade are prone to damage. In addition, the circular saw blade can also generate a certain amount of heat when cutting objects for a long time, which can cause the teeth of the circular saw blade to deform.

[0004] When a circular saw blade becomes deformed or damaged in a localized area, it can only be replaced as a whole, resulting in material waste. Therefore, it is necessary to develop a circular saw blade that can replace locally damaged or deformed blades. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a circular saw blade with replaceable partial saw blades, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] A circular saw blade with replaceable partial saw blades includes: a saw blade body, a first clamping block, saw blade gaps, heat dissipation holes, and mounting holes. The saw blade body comprises several pieces arranged in a circular ring. One end of each saw blade body is bent in one direction, and the bent portion is embedded in a receiving groove starting above the second clamping block. The side of each saw blade body facing the bent portion is in close contact with the upper surface of the second clamping block, and the other side of each saw blade body is against the lower surface of the first clamping block. The first clamping block has a circular ring extending and protruding in one direction on one side facing the second clamping block, and the second clamping block has an engaging ring on one side facing the first clamping block. The engaging ring is engaged with the circular ring. A saw blade gap is provided between each of the saw blade bodies.

[0007] The receiving slots are provided in several ways, and each slot corresponds to a saw blade body.

[0008] Each saw blade body has a toothed edge at the end away from its bend; the saw blade gaps between several saw blade bodies are the same width as several receiving grooves, and the width is no more than two millimeters.

[0009] The outer or inner side of the ring is provided with a thread, and the ring is threaded into the engagement ring; the first clamping block is clamped on several saw blade bodies by the mutual connection of the engagement ring of the ring and the engagement ring of the second clamping block; the receiving groove and the engagement ring are arranged sequentially from the outside to the inside.

[0010] An installation hole is provided at the center of the first clamping block and the second clamping block.

[0011] The first clamping block and the second clamping block have an outward-facing side that is inclined, and several tightening strips are provided on the outward-facing side of the inclined side; the first clamping block and the second clamping block have a flat surface on the outward-facing side that is adjacent to the inclined surface, and several positioning holes are provided on the flat surface of the first clamping block and the second clamping block.

[0012] Several saw blade bodies have through-holes on their surfaces.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention involves placing four saw blade bodies flat and sequentially inserting the bent ends into the receiving grooves. A first clamping block is then placed on top of these saw blade bodies, and finally, the first clamping block engages with the engagement ring of a second clamping block. This clamping and fixing of the saw blade bodies is achieved by the first and second clamping blocks. After clamping and fixing, the invention can be installed on a circular saw. If one of the four saw blade bodies is damaged or deformed during operation, the damaged saw blade body can be disassembled and removed by loosening the first and second clamping blocks, and another saw blade body can be installed to fill the gap. This method reduces the need to replace the entire circular saw blade after partial damage, thus avoiding increased costs. Attached Figure Description

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] like Figures 1 to 4 As shown, a circular saw blade with replaceable partial saw blades includes: a saw blade body 1, a first clamping block 2, a saw blade gap 3, a heat dissipation hole 4, and a mounting hole 5. The saw blade body 1 is provided with several pieces, which are arranged in a circular ring around each other. The ends of the saw blade bodies 1 facing each other are bent in one direction, and the bent ends of the saw blade bodies 1 are embedded in a receiving groove 24 starting above a second clamping block 20. The side of the saw blade bodies 1 facing the bent ends is in close contact with the second clamping block 20. On the upper surface of the clamping block 20, the other side of several saw blade bodies 1 is connected to the lower surface of the first clamping block 2; the first clamping block 2 has a ring 23 on one side facing the second clamping block 20 and protrudes in one direction, and the second clamping block 20 has a meshing ring 24 on one side facing the first clamping block 2, and the meshing ring 24 and the ring 23 are meshed and connected; a saw blade gap 3 is provided between several saw blade bodies 1; several receiving grooves 24 are provided, and each corresponds to a saw blade 1.

[0021] Each saw blade body 1 has a toothed pattern at one end away from its bend; the saw blade gap 3 between several saw blade bodies 1 has the same width as several receiving grooves 24, and the width is no more than two millimeters.

[0022] This invention involves placing four saw blade bodies 1 flat together and sequentially inserting the bent ends into the receiving grooves 24. A first clamping block 2 is then placed on top of these saw blade bodies 1. Finally, the first clamping block 2 engages with the engagement ring 24 of the second clamping block 20 using a ring 23. This clamping and fixing mechanism secures the saw blade bodies 1. After this engagement and fixing, the invention can be installed on a circular saw. If one of the four saw blade bodies 1 is damaged or deformed during operation, the damaged saw blade body 1 can be disassembled and removed by loosening the first and second clamping blocks 20, and another saw blade body 1 can be installed to fill the gap. This method reduces the need to replace the entire circular saw blade after partial damage, thus minimizing the increased cost associated with complete replacement.

[0023] After adopting the above structure, it should be further explained that the saw tooth body 1 of this utility model can be configured in several ways as needed, and there is a gap between the saw tooth bodies 1. This arrangement can prevent one saw tooth body 1 from impacting another independent saw tooth body 1 when it is sawing an object, thus avoiding damage between them. In addition, the receiving groove 24 can be increased or decreased according to the number of saw tooth bodies 1 configured.

[0024] The saw blade gap 3 serves not only to reduce collisions between saw blade bodies 1, but also to dissipate heat between saw blade bodies 1.

[0025] The bend in the saw tooth body 1 of this utility model is used to provide installation for the saw tooth body 1, so as to avoid the saw tooth body 1 being ejected outward by centrifugal force due to the rotation of the saw tooth body 1 by external equipment when the first clamping block 2 and the second clamping block 20 clamp the saw tooth body 1. At the same time, the installation method of embedding the bend in the receiving groove 24 of the saw tooth body 1 also provides quick positioning and fixation, avoiding the need to manually adjust the gap and positioning between the saw tooth bodies 1.

[0026] A thread is provided on the outer or inner side of the ring 23, and the ring 23 is threaded into the engagement ring 24; the first clamping block 2 is clamped on several saw blade bodies 1 by the mutual connection between the ring 23 and the engagement ring 24 of the second clamping block 20; the receiving groove 24 and the engagement ring 24 are arranged sequentially from the outside to the inside; a mounting hole 5 is provided at the center of the first clamping block 2 and the second clamping block 20.

[0027] With the above structure, it should be further explained that the meshing method allows for tight clamping between the first clamping block 2 and the second clamping block 20. When the external device drives the present invention to rotate, the tips of the teeth of several saw teeth body 1 rotate downwards, while the meshing between the first clamping block 2 and the second clamping block 20 meshes in the opposite direction, thus preventing loosening between the first clamping block 2 and the second clamping block 20 when the present invention rotates.

[0028] The first clamping block 2 and the second clamping block 20 are inclined on their respective outward-facing sides, and several tightening strips 22 are provided on the outward-facing sides of the first clamping block 2 and the second clamping block 20. A flat surface is provided on the outward-facing side of the first clamping block 2 and the second clamping block 20, which is adjacent to the inclined surface, and several positioning holes 21 are provided on the flat surface of the first clamping block 2 and the second clamping block 20.

[0029] With the above structure, it should be further explained that each of the tightening strips 22 is a strip-shaped groove, which is embedded by a matching sheet from the outside and fixes the second clamping block 20. When the sheet is moved, the first clamping block 2 is twisted, so that the ring 23 of the first clamping block 2 engages with the engagement ring 24.

[0030] The positioning holes 21 are used to provide positioning for external installation equipment when installing this utility model.

[0031] Several saw blade bodies 1 have vertically connected heat dissipation holes 4 on their surfaces.

[0032] After adopting the above structure, it should be further explained that the heat dissipation holes 4 opened on the surface of several saw blade bodies 1 are used to increase the heat dissipation surface of the saw blade body 1, avoid the accumulation of heat generated by friction during the sawing process, and at the same time, they can also carry out the debris in the saw kerf of the object during the sawing process.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
