Cutting angle processing technology in stone processing
The process of chamfering in the processing of stone products is very common, but it is very important. The quality of the chamfer directly affects the quality of the processed products. The chamfering angle does not meet the quality requirements, resulting in the installation of the product, or the installation gap is too large, which has a very adverse impact on the construction of the site. The light impact on the progress of the on-site construction. If it is serious, the relationship between the supplier and the construction party will be tense. It is not conducive to the smooth development of the project. This article talks about some of my experiences on the chamfering process. The term "corner" mentioned in construction is different from the concept of "corner" in our daily life. But they are also closely related to each other. The term in the geometric mid-angle refers to the measure of the amount that must be rotated when any one of the two intersecting lines overlaps with the other. The rotation is made on the plane of the two straight lines and around the intersection. First, the name of the corner in stone processing 1. Positive angle: After the two pieces or two lines are cut at the corners, the formed lobes are called the male angles. see picture 1. Usually the angle of the square column is a positive angle. 2. Yinjiao: After the two pieces or two lines are cut at the corners, the concave angle formed is a female angle. See Figure 2. Usually the angle formed by adjacent walls in the room is a female angle. 3. Arc angle: The angle between the side of the arc and the length of the chord. 4. End face angle: From the end face of the line at a certain angle along the thickness direction of the line, the cut end face angle is cut from the end point of the end face along the length direction to cut the end face angle. 5. Three-dimensional shaped angle: This is a more troublesome angle-cutting method in stone processing, and it is a special form of cutting end angle. As can be understood from Fig. 5, the so-called three-dimensional angle is a special case in which the bottom surface of the line is at an angle to the table and then the end face angle is cut. It can be seen from the decorative drawing on the right of Fig. 5 that the line is not mounted on the facade with the decorative surface, but on the other decorative surface, so-called in the three-dimensional space. 6. Plane profile angle: The angle between the adjacent edge to be cut and the edge to be cut and the adjacent edge when the profiled plate of various geometric figures is processed. 7. Spiral lift angle of the spiral staircase: the spiral angle of the spiral staircase. 8. Corner: The angle at which different elevations are connected. 9. Bottom angle: The part of the bottom of the line is called the bottom corner. See Figure 9. 10. Face angle: Cut a part of the front face from the front of the line at an angle to the thickness of the line at an angle. The end face angle, the face angle and the bottom angle are actually the same, but the angle of cut is caused by the change in the thickness of the workpiece and the change in the width direction. Second, the cut angle map A graph that reflects the relationship between adjacent products. Generally, the degree of chamfering is 45°, 60°, and 67.5°. In particular, the angle is cut at a maximum of 45°. 1. Wall-to-wall or waistline chamfering, as shown in Figure 11. The corner elements that should be marked in the chamfer: 1 a large section of the line; 2 Indicates the indication of the inside and outside direction of the large-scale installation of the line. You can use ┄┄ to indicate the installation direction of the line or the light surface on the plan; you can also use Chinese “outside†and “inside†to indicate the installation direction of the line; 3 angle of the chamfer; 4 installation number; 5 Mounting dimensions. 2. Arc cut angle diagram Common cut angle maps have three round cut angle maps, four round cut angle maps, and six round cut angle maps. The cut angles are 30°, 45°, and 60°, respectively. The corner elements that should be marked in the chamfer: 1 angle of the chamfer; 2 inner and outer strings are long. The inner arc sees the inner arc of the light, and the outer arc sees the outer arc of the light; 3 Use ┄┄ to indicate the inside and outside direction of the glossy surface; 4 Numbering of the splicing relationship and order. Expressed in English letters or Arabic numerals, the direction of the stitching sequence is indicated by the → sign. 3. Three-dimensional chamfering 1 line profile 2 indicates the indication of the inner and outer directions of the large-scale installation of the line. You can use ┄ to indicate the installation direction of the line or the light surface on the plan; you can also use Chinese “outside†and “inside†to indicate the installation direction of the line; 3 angle of the chamfer; 4 installation number; 5 The angle between the large sample and the vertical direction; 6 Mounting dimensions. 4. Door cover cut 1 a large section of the line; 2 Installation number and direction number; 3 indicates the indication of the inner and outer directions of the large-scale installation of the line. 5. Square column chamfering 1 a large section of the line; 2 Installation number and direction number; 3 indicates the indication of the inner and outer directions of the large-scale installation of the line; 4 Mark the line width on the chamfered plan. 6. Rotating stairs chamfer Third, the method of chamfering 1. Template method. Compared with the standard template chamfering angle, it is mostly used for conical arc plate, spiral staircase, arc column seat, column head, curved line, elliptical board and other irregular shaped products. 2. Die cushioning method 3. Symmetry Place the product processing workpiece symmetrically. This method can improve the working efficiency of the chamfering angle and cut two pieces in one piece. However, it should be noted that the angle cut by this method is positive and negative, and can only be used in the chamfering of the positive and negative directions. 4. Parallel method The multiple products are arranged close together in a parallel manner, as shown in Fig. 19. With this method, the angle is cut, and the multiple pieces are cut together to meet the optimal processing principle, which can greatly improve the production efficiency. 5. Nesting This method can not only improve the cutting angle efficiency, but also improve the output rate of the main material. Pay attention to increasing the margin of the knife thickness when opening the material. Fourth, the angle of the mechanical equipment 1. Electronic bridge cutting machine. It is best to work like lifting, so that the depth of the chamfer can be deeper; 2. Small cutting machine (bed/cutting machine); 3. φ1200 circular saw. Cutting angle for large workpieces; 4. The machine head can rotate the vertical edge machine; 5. Other machine tools that can cut boards. When cutting any product, the operator must make the corresponding positioning plate. The method of chamfering positioning is described with reference to the method of "three" chamfering. In addition, the three-dimensional chamfering angle can also be drawn by Autocad three-dimensional drawing, and then the XYZ coordinate plane is established on ACG and CEF in three-point fixed plane in Autocad, and the angle is marked by angle. Get the desired angle. Fifth, the quality requirements of the chamfer 1. The error of the door cover and the cutting angle: ±0.5°; 2. The cutting angle error of the cylindrical column foot and the column head: ±0.5°. When the end of the column foot and the column head sees light, the error is 0; 3. Angle of cut angle of arc plate: ±0.5°. When the end face of the circular arc plate sees light, the error is 0; 4. The angle of the chamfer of the circular arc plate should be checked for the chamfering template; 5. Error in the bottom/face angle: -2°. When the side of the board or line sees light, the error is zero.
