Description

Technical Field

[0002] With the rapid development of the stone processing industry and modern industry, diamond circular saw blades have been widely used in the cutting and processing fields of non-metallic materials such as stone, cement, glass, and ceramic products. A diamond circular saw blade consists of diamond teeth and a circular saw blade body. The tower-type combined circular saw blade is widely used in the stone plate processing field due to its high efficiency. However, the different tooth lives of the saw blades of different bodies in the combined saw greatly limit the production efficiency, processing quality, and cost of the combined saw.

[0003] The inventor found that the tower-type combined diamond circular saw blades widely used in the market at present mainly include 4 sets, 8 sets, etc., and the largest set can reach 26 pieces in combination. There are problems that the tooth wear degrees of the saw teeth of circular saw blades with different diameters are different. The saw teeth of the circular saw blade with a smaller outer diameter specification are more severely worn than those with a larger outer diameter specification, resulting in frequent replacement of the circular saw blade with a smaller outer diameter specification, which affects the work efficiency and processing cost. The selection of the number of teeth is the key to alleviating the problem of different tooth wears of circular saw blades with different diameters. In existing projects, it is a major problem that the number of teeth of the combined circular saw blade cannot be accurately selected, resulting in serious waste of diamond circular saw blade tools, greatly reducing the overall life of the combined saw, increasing the cost of replacing the diamond circular saw blade, and seriously affecting the production efficiency.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0036] The tower - type combined diamond circular saw blade refers to a combination of circular saw blades with various diameters. They are installed on the main shaft and fixed flange of the same sawing machine in ascending or descending order according to the outer diameter specifications, and are used as a tool for cutting plates. Since the tower - type combined diamond circular saw blades are coaxially installed on the sawing machine main shaft, the diamond circular saw blades from small to large or from large to small have the same rotational speed and feed speed within the same time. During the process of sawing rough blocks or plates, the diamond circular saw blades have different service lives due to different diameters. It is mainly used for cutting granite and other stone rough blocks and marble plates, improving the yield rate of rough blocks, saving power consumption, and improving cutting efficiency and plate precision.

[0037] Embodiment 1:

[0038] This embodiment provides a method for calculating the number of teeth of a tower - type combined diamond circular saw blade, including:

[0039] Obtain the saw blade diameter, as well as the angular velocity, feed speed, sawing depth, and sawing speed of the saw blade under preset working conditions;

[0040] After adding 1 to the ratio of the feed speed to the sawing speed, and then multiplying by the square root of the product of the sawing depth and the saw blade diameter, the contact arc length is obtained;

[0041] According to the maximum undeformed chip thickness equation, calculate the maximum undeformed chip thickness;

[0042] Calculate half of the product of the contact arc length and the maximum undeformed chip thickness to obtain the cross - sectional area of the undeformed chip;

[0043] Take the product of the first constant and pi, the saw tooth width, the three - halves power of the feed speed, and the square root of the saw blade diameter as the numerator, and take the second constant, the total number of diamond particles per unit width on the saw tooth, the proportion of diamond particles participating in sawing in the cross - section to the total number of particles in the cross - section, the tangent value of the angle rotated by the saw blade, the spindle angular velocity, and the calculated cross - sectional area of the undeformed chip as the denominator; take the ratio obtained from the denominator and the numerator as the first multiplier; take the ratio of the product of the third constant and the feed speed to the product of the spindle angular velocity and the saw blade diameter, and then add 1 squared as the second multiplier; calculate the product of the first multiplier and the second multiplier to obtain the number of saw blade teeth.

[0044] As Figure 1 shown, the main steps implemented in this embodiment are:

[0045] S1. Determine the diameter of the circular saw blade matrix and the reference number of teeth according to the existing standard dimensions;

[0046] The diameter of the substrate can be understood as the average value or the median value of the diameters of standard circular saw blades of various specifications in a tower-type combined diamond circular saw blade composed of circular saw blades of various specifications; the reference number of teeth is the average value or the median value of the number of teeth of standard circular saw blades of various specifications in a tower-type combined diamond circular saw blade composed of circular saw blades of various specifications.

[0047] S2. Determine the rotational speed n of the diamond circular saw blade, the workpiece feed speed v f and the sawing depth a p etc. Here, the rotational speed n of the diamond circular saw blade, the workpiece feed speed v f and the sawing depth a p etc. can be obtained through conventional design or directly measured according to relevant actual working conditions as the relevant parameters of the preset working conditions.

[0048] S3. Calculate the length of the sawing arc zone and the maximum undeformed chip thickness by geometric calculation of the undeformed chip according to the sawing working conditions.

[0049] S3.1. Calculate the length of the sawing arc zone according to the sawing working conditions:

[0050] The diameter of the substrate or the actually measured diameter can be used as the saw blade diameter d s , the circular saw blade rotates at an angular velocity n or an angular velocity ω, and moves relative to the workpiece at a feed speed v f . The sawing depth of the circular saw blade for the granite workpiece is a p . In the actual process of sawing granite, a p is very small, and the sawing speed v s is much greater than the feed speed v f . Therefore Figure 3 the sawing arc in is exaggerated. Establish an X-Y coordinate system with point D' as the origin. When the circular saw blade rotates through an angle θ', its horizontal and vertical movements are both:

[0051]

[0052] The contact arc length can be obtained from the sawing path; as Figure 3 shown, the horizontal distance s between the sawing of the granite workpiece by two adjacent saw teeth is s = Lv f / v s . L represents the distance between the first row of diamonds of two adjacent diamond saw teeth. The total contact arc length can be obtained by integrating the angle 0→θ:

[0053]

[0054] In the formula, dl k is obtained from the sawing path equation.

[0055]

[0056] Since θ is a small angle, the quantities of its second power and higher powers are neglected compared with the first quantity. L represents the distance between two adjacent cutting edges, that is, the distance between two adjacent diamond particles. Therefore, the contact arc length can be simplified as:

[0057]

[0058] S3.2. Calculate the maximum undeformed chip thickness according to the undeformed chip geometry:

[0059] According to the grinding theory, the diamond particles on the cutting section are defined as the cutting edges, and the maximum undeformed chip thickness removed by the cutting edges is expressed as the maximum undeformed chip thickness. Establish the h m model:

[0060]

[0061] Through the analysis of the chip geometry, the maximum undeformed chip thickness formed when sawing granite is obtained. Among them, C i = C g ηλ / (l s ), C g is the total number of diamond particles per unit width on the saw tooth, η is the proportion of diamond particles participating in sawing in the cross section to the total number of particles in the cross section. Since the sawing process is intermittent machining, λ is expressed as the intermittency ratio, where λ = l s / (l s + l w ), l s is the saw tooth length, B is the saw tooth width, z is the number of teeth, ω is the main shaft angular velocity, r is the half included angle of the diamond particle point cutting surface shape, considered by a triangular cross section, and expressed as tanθ in this embodiment. The maximum undeformed chip thickness of the diamond particle on the section is defined as h mi . Substitute C g into the following formula, and the maximum undeformed chip thickness equation can be expressed as:

[0062]

[0063] S4. Calculate the cross-sectional area of the undeformed chip through the sawing arc zone length and the maximum undeformed chip thickness;

[0064] During the sawing process of diamond particles, through theoretical analysis, the cross-sectional area of the undeformed chip is simplified to a right triangle with the sawing arc zone length as the height and the maximum undeformed chip thickness as the base. Then, the calculation of the cross-sectional area of the undeformed chip can be obtained through the undeformed chip thickness and the sawing arc length:

[0065]

[0066] S5. Calculate the tooth number function model based on the geometric parameters of the saw teeth practical in engineering;

[0067] According to the previous analysis and calculation, the load-bearing work amount of a single diamond particle is approximately expressed by the cross-sectional area of the undeformed chip. Select the cross-sectional area corresponding to the number of teeth of a certain diamond circular saw blade as the benchmark. Therefore, the tooth number function model can be obtained through the cross-sectional area of the undeformed chip of the diamond particle:

[0068]

[0069] S6. Determine the cross-sectional area of the undeformed chip according to the reference circular saw blade of the combined blade set;

[0070] S7. Calculate the number of teeth of the combined blade through the tooth number function model;

[0071] In a specific embodiment, within the range of a diamond circular saw blade with a certain outer diameter, the maximum cross-sectional area of the undeformed chip corresponding to the number of teeth of a diamond circular saw blade with a certain outer diameter is the optimal. Then, based on the existing data of saw tooth engineering measurement, C g = 60, η = 0.667, tanθ = 1.714. The machining parameters are selected as the commonly used sawing machining parameters in engineering. Secondly, determine the number of teeth of the reference diameter circular saw blade, calculate the cross-sectional area of the undeformed chip corresponding to its reference diamond circular saw blade, and calculate the number of teeth using the sawing cross-sectional area of the undeformed chip.

[0072] S8. According to the principle that the number of teeth of the circular saw blade should be an integer, round and fine-tune the number of teeth;

[0073] For the convenience of actual production, the calculated number of teeth needs to be adjusted to an even number, and then this even number is taken as the designed number of teeth; for the case where the integer part of the calculated number of teeth is odd, either adding one or subtracting one from the odd number is taken as the selected number of teeth as the final result.

[0074] S9. Judge whether the number of teeth meets the design requirements. If not, return to step S2; otherwise, take the above-determined number of teeth as the final result.

[0075] This application only assumes that within a certain range of the outer diameter of the diamond circular saw blade, the number of teeth of the diamond circular saw blade corresponding to a certain outer diameter is the optimal. Based on this, the cross-sectional area of the undeformed chip in this case is calculated, and the number of teeth of the diamond circular saw blade with other outer diameters is calculated through the tooth number function model. Then, for the convenience of production, the number of teeth is slightly adjusted as the final design solution to solve the problem of inconsistent service lives of the diamond circular saw blades of the combined saw, improve the overall service life of the combined saw, reduce the cost of replacing the diamond circular saw blade, and improve the production efficiency. Subsequently, the staff can change the sawing process parameters, the tooth structure parameters, and the number of diamond inserts, or change the maximum cross-sectional area of the undeformed chip corresponding to the reference diamond circular saw blade, and calculate the number of teeth of the diamond circular saw blade of the combined saw based on the tooth number function model of the combined saw of this application.

[0076] Example 2:

[0077] On the basis of Example 1, this example provides an explanatory description of a calculation method for the number of teeth of the tower-type combined circular saw blade based on the equal cross-sectional area of the undeformed chip; the commonly used process parameters in the project are selected: the feed rate is 8 m / min; the sawing depth is 5 mm; the rotational speed is 300 rpm / min. A conventional tooth structure is selected, and the number of exposed particles on the tooth surface is 60. Then, the number of teeth for the diamond circular saw blade with a diameter of 26 is implemented as shown in Table 1:

[0078] Figure 1 Implementation of the number of teeth for the diamond circular saw blade with a diameter of 26

[0079]

[0080]

[0081]

[0082] In Table 1, within the range of the outer diameter of the diamond circular saw blade from 400 to 1050 mm, assuming that the diamond circular saw blade with an outer diameter of 550 mm has the highest service life under the above sawing conditions, the diamond circular saw blade with an outer diameter of 550 mm is selected as the reference diameter diamond circular saw blade; within the range of the outer diameter of the diamond circular saw blade from 1100 to 1650 mm, assuming that the diamond circular saw blade with an outer diameter of 1100 mm has the highest service life under the above sawing conditions, the circular saw blade with an outer diameter of 1100 mm is selected as the reference diameter diamond circular saw blade; the cross-sectional area of the undeformed chip corresponding to its reference diamond circular saw blade is brought into the tooth number function model to calculate the number of teeth of other diamond circular saw blades; for the convenience of actual production, according to the fine-tuning tooth number scheme, fine-tuning and rounding are carried out, and an even number is selected as the final result.
