Description

Technical Field

[0001] The invention relates to the technical field of stone processing, in particular to a processing technology of special-shaped stone strips and a preparation method thereof. Background Art

[0002] Stone is an indispensable material for human construction and decoration. With the gradual improvement of living standards, people have put forward higher and higher requirements for stone processing. On the basis of the original long straight stone strips, there are more demands for special-shaped stone strips with curved outer contours. Stone processing is an industry with traditional skills, and many of the processes are relatively traditional. For example, after the traditional stone strips are roughly processed by profiling equipment according to the line pattern template, they need to be polished bit by bit by workers using angle grinders and diamond grinding discs. It completely depends on the skills and strength of the craftsmen themselves, and cannot guarantee the smoothness of the lines and the consistency of batch processing, which will affect the quality stability of batch products and is not conducive to modern industrial needs.

[0003] At present, the stone line machine is a stone processing equipment that can repeatedly process decorative lines on stones in batches. It can also be used for grinding and processing processed stones, etc. It is suitable for various different stones such as ceramics, marble and granite. For example, the existing Chinese patent CN216327313U discloses a gantry-type stone line machine for building stone processing, which includes a base, the top of the base is fixedly connected to a transport frame, one side of the base is fixedly connected to a side box, the top of the side box close to the transport frame is fixedly connected to a top box, the bottom of the transport frame is provided with a through groove, and the bottom of the through groove is provided with a collection box. With the above technical solution, the cleaning head can be controlled to clean the processed stone when grinding, and the stone powder falling on the conveyor belt can be collected to protect the environment. However, the above technical solution can only fix stones of the same width. When processing stones of different widths, it is necessary to stop processing and adjust the width of the fixing mechanism, thereby increasing the complexity of the worker's operation.

[0004] In addition, another Chinese patent CN218139027U also discloses a stone line processing device, which includes a frame, a plurality of cutting frames are arranged at intervals above the middle of the frame, and a cutting assembly is movably arranged at the four corners of the top of each cutting frame, and a transverse device is arranged on the top of the frame, and a cutting table is transversely mounted on the transverse device, and the cutting table is located below the cutting assembly. The stone line processing device can form the product in one step, realize product automation, and has high work efficiency.

[0005] In general, there are two main types of stone line processing technologies currently known: one is to use a saw blade for longitudinal cutting, and after cutting a knife, move horizontally by a distance of the thickness of the blade. When moving horizontally, it is raised and lowered according to the shape of the pre-made template or the shape set by the CNC system. This operation is repeated to process the flat stone slab into stone lines with straight lines in the vertical direction and high and low drops in the horizontal direction. This type of processing equipment is very inefficient because it can only use one saw blade to process the same product at a time, and it can only shape but not polish. The second is to use multiple forming wheels made according to the required line shape, such as sintered diamond or electroplated, brazed diamond grinding wheels; to grind the plate so that the flat stone slab forms straight lines in the vertical direction and lines with high and low drops in the horizontal direction. This processing equipment is currently a commonly used processing method, but since this equipment needs to replace the forming grinding wheel for each line shape, it takes a long time to replace the grinding wheel. After replacing the grinding wheels of different shapes, it needs to be re-calibrated, and the adjustment takes a long time. In addition, due to different market demands, many types of line shapes are required, which requires the equipment of many types of grinding wheels, causing great cost investment for manufacturers.

[0006] However, current technologies focus on improving the processing equipment itself to solve the problem of stone processing efficiency; they do not optimize the production process according to the shape and structure of stone products in order to improve the processing mode. The current special-shaped stones have curved linear structures that alternate on multiple processing surfaces, which puts forward high requirements for further improvement of equipment, making the current processing equipment structure more complex; and resulting in high costs for stone processing, making it difficult to promote. Summary of the invention

[0007] Based on this, it is necessary to provide a special-shaped stone bar processing technology and a preparation method thereof to address the technical problem of how to efficiently process special-shaped stones.

[0008] A special-shaped stone bar processing process comprises the following steps: S1: cutting the stone bar stock slab into stone bar stock strips; S2: Take the worktable of the five-axis CNC machining center as the working plane, and set and fix the positioning plate along its machining origin, X-axis and Y-axis; S3: aligning the vertex of the bottom rectangle of the stone bar preparation strip with the machining origin position of the five-axis CNC machining center, and then making the two sides of the bottom rectangle of the stone bar preparation strip close to the positioning plate; then, fixing the stone bar preparation strip with a movable clamp, and then using a preset machining trajectory to process one surface of the stone bar preparation through the five-axis CNC machining center to prepare a stone bar semi-finished product with a single curved surface; S4: The back arc surface of the semi-finished stone strip is turned downward, and the vertex of the back rectangle of the semi-finished stone strip is aligned with the original processing origin of the five-axis CNC machining center; and the two sides of the back rectangle of the semi-finished stone strip are close to the positioning support plate; then, the semi-finished stone strip is fixed by a movable clamp, and the other side of the semi-finished stone strip is processed to prepare another curved surface of the stone strip; S5: Repeating steps S3 and S4 can produce a finished product of a special-shaped stone bar having multiple curved surfaces.

[0009] More specifically, in a specific embodiment of a special-shaped stone bar processing process of the present invention, it includes the following steps: S1: Prepare a list of stone bar preparation materials and a stone bar numbering diagram in advance, and then process and prepare stone bar preparation slabs one by one according to the list of stone bar preparation materials; then, cut the stone bar preparation slabs to obtain stone bar preparation strips; then, mark the end faces of the stone bar preparation strips one by one according to the stone bar numbering diagram; S2: Determine the machining origin position of the five-axis CNC machining center on the workbench, take the workbench as the working plane, and set and fix the positioning plate along the X-axis and Y-axis passing through the machining origin; S3: Mark the finished surface of the stone strip at the end of the stone strip where the stone strip number is marked; S4: The finished surface of the stone strip preparation strip is facing inward, the vertex of the bottom rectangle of the stone strip preparation strip is aligned with the processing origin, the two sides of the rectangle of the stone strip preparation strip are close to the positioning support plate, and the stone strip preparation strip is fixed with a movable clamp for processing; S5: Import the processing file of the five-axis CNC processing trajectory of the outer frame line of the finished surface of the stone strip corresponding to the stone strip number and the outer frame line of the side view in the length direction of the stone strip; then align the five-axis CNC processing trajectory of the outer frame line of the side view in the length direction of the stone strip with the processing origin and the X-axis and Y-axis in the control screen of the five-axis CNC processing center; S6: Operate the five-axis CNC machining center to process the back arc surface and the finished arc surface of the stone strip in sequence; S7: Take out the semi-finished product after the finished surface processing and the back arc processing of the stone strip, then turn the back arc surface of the semi-finished stone strip downward, align the vertex of the back rectangle with the original processing origin, close the two sides of the rectangle to the positioning support plate, and fix the semi-finished stone strip with a movable clamp; S8: Align the five-axis CNC machining trajectory of the outer frame line of the finished surface of the stone strip with the machining origin and the X-axis and Y-axis on the control screen of the five-axis CNC machining center again; S9: Continue to operate the five-axis CNC machining center to sequentially complete the processing of the outer frame of another stone strip finish surface; S10: Take down the stone strips and mark the stone strip numbers on the back of the stone strips; put the stone strips into storage according to the numbers or continue to perform auxiliary processing on the stone strips and then put them into storage according to the numbers.

[0010] More specifically, before step S1, a pre-production preparation step is performed, specifically: S11: Design and summarize the 3D model of the entire stone processing area; S12: 3D model diagram of the separated design of a single stone bar; S13: Number all the stones in the processing area one by one, and output them into a stone strip numbering map; S14: Design and organize the schematic diagram of the classified drilling positions of a single stone bar; S15: sort out and output the material list of the stone strips, which includes the stone strip number, the length and width of the finished product, the material and the surface treatment information.

[0011] More specifically, after completing the pre-production preparation process, continue to deepen the stone strip processing drawings, as follows: S21: Classify all the stone strips to be processed according to the structural form categories; S22: Calculate the material size of a single stone with a curved surface, and the calculation rule is: material length = maximum straight length of the stone bar + 4 cm, material width = maximum straight width of the stone bar + 2 cm, and output the material list; S23: using graphic design software to design and output the five-axis CNC machining trajectory of the outer frame lines of the finished surface of the stone strip and the side view outer frame lines in the length direction of the stone strip, and centering them with the outer frame rectangle of the corresponding preparation surface; S24: Mark the short groove and hole position size of each stone strip one by one; S25: Design and output the five-axis CNC machining trajectory of the long groove lines of the stone strips one by one, and center them with the outer frame rectangle of the corresponding preparation surface; S26: The detailed stone processing drawings are saved as corresponding processing procedures according to the stone strip numbers.

[0012] More specifically, each time a curved surface of the semi-finished stone strip is processed, the curved surface of the semi-finished stone strip can be further subjected to a litchi surface treatment process.

[0013] More specifically, between every two processes of processing the curved surface of the semi-finished stone strip, the solid semi-finished product can be subjected to auxiliary processing steps, specifically: processing short grooves and drilling holes in the stone strip according to the size of the short grooves and drilling positions, detecting the size accuracy of the corresponding parts of the stone strip according to the requirements of the stone strip processing accuracy, trimming the R angles of the four sides of the finished surface of the stone strip, backing the back of the stone strip with a stainless steel backing net, installing anti-fall wire ropes on the stone strips, and performing six-sided protection and soaking treatment on the stone strips.

[0024] Next, it is necessary to deepen the stone strip processing drawings, which include the following steps: 1. Classify all the stone strips to be processed according to their structural forms. For example, they can be divided into four types: flat straight sections, flat long arc edges, cylindrical straight edges, and hyperbolic arc stone strips; 2. Calculate the size of the single stone material for each straight edge of the cylindrical surface and each hyperbolic arc stone strip. The technical rules are: material length = maximum straight length of the stone strip + 4CM, material width = maximum straight width of the stone strip + 2CM, and output the material list; 3.
