[0003] First of all, PVC integrated wall panels are often used in the decoration of bathrooms and kitchens. Since these areas are easily eroded by water vapor and moisture, the use of PVC integrated wall panels can effectively prevent the wall from mold, corrosion and deformation.

[0004] In addition, PVC integrated wall panels are easy to clean, and stains can be easily wiped off to keep the wall clean.

[0005] Secondly, PVC integrated wall panels are also commonly used in the decoration of living rooms and bedrooms. They can be used for wall decoration, providing a variety of colors and textures to make the room more beautiful.

[0006] In addition, PVC integrated wall panels can also be used to build partition walls, dividing the space into different functional areas and increasing the practicality and flexibility of the room.

[0007] PVC integrated wall panels can also be used to decorate balconies and porches. They effectively protect balconies and porches from rain and sunlight, extending their service life. At the same time, PVC integrated wall panels can also provide a certain degree of privacy protection, making balconies and porches a comfortable leisure space.

[0008] In addition to the above application range, PVC integrated wall panels can also be used for the decoration of commercial places such as restaurants, shops and offices. It can provide a variety of colors and textures to meet the decoration needs of different places.

[0009] At the same time, PVC integrated wall panels are easy to install and maintain, saving time and cost.

[0010] In short, PVC integrated wall panels have a wide range of applications in home decoration. Whether it's a bathroom, kitchen, living room, bedroom, balcony, or porch, PVC integrated wall panels offer advantages such as waterproofing, moisture resistance, mildew resistance, and corrosion resistance, making the decoration more beautiful, practical, and durable. They are also easy to clean, install, and maintain, bringing convenience to home decoration. Therefore, choosing PVC integrated wall panels as a decoration material is a wise choice and has a wide range of applications in home decoration. PVC integrated wall panels are generally cut using a precision sliding table saw. The PVC integrated wall panels are fixed to the sliding table, and the main motor drives the saw blade to rotate. As the sliding table moves forward, the integrated wall panels are cut.

[0011] However, in actual cutting operations, PVC integrated wall panels are cold and brittle due to the material properties, and are prone to chipping and corner loss during cutting. In addition, due to the need to improve sound insulation, heat preservation, and material utilization, PVC integrated wall panels are designed with many small holes inside, and the cross-section forms a thin mesh structure. During sawing, factors such as shaking of the circular saw blade, unreasonable angles, and bluntness will cause the cut workpiece to tear and break. However, there is a lack of special PVC cutting saw blades on the market. When traditional saw blades cut PVC boards, because the front cutting surface of the saw blade is usually flat and the tooth shape is usually alternating teeth, this causes greater pressure on the board surface during cutting, and the cut part has a larger particle size, which can easily lead to chipping, tearing, and breakage. For this reason, a special cutting saw blade for PVC integrated wall panels is provided to solve the above problems. Utility Model Content

[0012] In response to the shortcomings of the existing technology, the utility model provides a special cutting saw blade for PVC integrated wall panels, which solves the problem that when sawing PVC integrated wall panels, the circular saw blade shakes, has an unreasonable angle, is not sharp, and other factors may cause the cutting workpiece to tear and break.

[0013] To achieve the above objectives, the present invention is implemented through the following technical solutions: a saw blade specifically for cutting PVC integrated wall panels, comprising a saw blade body and an integrally formed cutter head arranged in a ring-shaped arrangement on the outer ring of the saw blade body, wherein the rake surface of the cutter head is arc-shaped, and the rake surface has an inclination angle λ of 32°;

[0014] The tooth shape of the cutter head is pointed flat teeth, and the pointed flat teeth include pointed teeth and flat teeth, and the pointed teeth and flat teeth are staggered.

[0015] Preferably, a mounting groove is provided in the middle of the saw blade body, and the mounting groove passes through the saw blade body.

[0016] Preferably, the radius R of the rake face of the cutting head is 3 mm.

[0017] Preferably, the tooth width K of the rake face of the cutter head is 3.2 mm.

[0018] Preferably, the main deflection angles ε on both sides of the pointed teeth are both 25°, and are bilaterally symmetrical.

[0019] Preferably, the tooth difference between the pointed teeth and the flat teeth is HD=0.30.

[0020] The utility model discloses a special cutting saw blade for PVC integrated wall panels, which has the following beneficial effects:

[0021] 1. By designing the rake face of the cutter head on the outer ring of the saw blade body from the commonly used flat teeth to concave arc teeth, the radius of the arc teeth is R=3, and the tooth width of the rake face is 3.2mm, so that the rake face of the cutter head has a blade inclination angle λ. According to the radius r and the tooth width of 3.2, the blade inclination angle λ=32° can be calculated. The use of the concave arc teeth greatly improves the sharpness of the cutter head tooth tip, and significantly reduces the pressure of the cutter head tooth tip on the surface of the PVC integrated wallboard during cutting, thereby avoiding or significantly reducing edge collapse, corner drop, and avoiding tearing and breakage.

[0022] 2. The tooth shape of the cutter head is changed from alternating teeth to pointed flat teeth, and the pointed teeth and flat teeth are staggered. The pointed teeth are ground into a main deflection angle ε = 25° and divided equally on the left and right. The radial pointed flat tooth difference HD between the pointed teeth and the flat teeth is 0.30. When in use, the pointed teeth can form 2 chips and the flat teeth can also form 4 chips, which further reduces the pressure of the tooth tip of the cutter head on the surface of the PVC integrated wallboard, thereby avoiding or significantly reducing edge collapse, corner drop, and avoiding tearing and breakage.

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] The embodiment of the present application solves the problem that when sawing PVC integrated wall panels, the circular saw blade shakes, has an unreasonable angle, is not sharp, and other factors may cause the cut workpiece to tear or break.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] The embodiment of the utility model discloses a special cutting saw blade for PVC integrated wall panels.

[0032] According to the attached Figure 1-3 As shown, it includes a saw blade body 1 and a cutter head 2 integrally formed and arranged in a ring shape on the outer ring of the saw blade body 1. An assembly groove 3 is opened in the middle of the saw blade body 1, and the assembly groove 3 passes through the saw blade body 1. The saw blade body 1 is installed with an external cutting machine through the assembly groove 3.

[0033] When traditional saw blades cut PVC boards, because the rake surface of the saw blade is usually flat and the teeth are usually alternating, this will cause greater pressure on the board surface during cutting, and the cut part will have a larger particle size, which can easily lead to edge chipping, tearing and breaking.

[0034] The device is designed by changing the rake face of the cutter head 2 on the outer ring of the saw blade body 1 from a commonly used flat tooth to a concave arc tooth. The radius of the arc tooth is R=3, and the tooth width of the rake face is 3.2 mm. This makes the rake face of the cutter head have a cutting edge inclination angle λ. The cutting edge inclination angle λ=32° is calculated based on the radius r and the tooth width of 3.2. The concave arc tooth greatly improves the sharpness of the cutter head tooth tip, significantly reduces the pressure of the cutter head tooth tip on the surface of the PVC integrated wallboard during cutting, thereby avoiding or significantly reducing edge chipping, corner drop, and preventing tearing and breakage.

[0035] At the same time, the tooth shape of the cutter head 2 is changed from alternating teeth to pointed flat teeth, and the pointed teeth and flat teeth are staggered. The pointed teeth are ground into a main deflection angle ε=25° and divided equally on the left and right. The radial pointed flat tooth difference HD=0.30 between the pointed teeth and the flat teeth. When in use, the pointed teeth can form 2 chips and the flat teeth can also form 4 chips, which further reduces the pressure of the tooth tip of the cutter head on the surface of the PVC integrated wallboard, thereby avoiding or significantly reducing edge collapse, corner drop, and avoiding tearing and breakage.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
