Description

Technical Field

[0001] The invention relates to the technical field of irregular model processing, and in particular to an irregular model processing technology. Background Art

[0002] CAM-assisted processing refers to the use of computer-aided technology to assist the processing process. Specifically, it is to achieve automated manufacturing through CAM software and CNC machine tools. CAM technology covers all production preparation activities from product design to processing and manufacturing, including CAPP, NC programming, calculation of labor quotas, formulation of production plans, formulation of resource demand plans, etc. CAM technology has a wide range of applications, covering multiple industries such as automobiles, aerospace, and electronics. It not only improves production efficiency and product quality, but also reduces human errors and production cycles, significantly improving the competitiveness and economic benefits of enterprises. Therefore, with the development of the times, the application of CAM-assisted processing has become more and more extensive.

[0003] In the actual production process, a set of models is usually composed of multiple model components, some of which are irregular in shape and difficult to fix during processing, resulting in a low success rate and the need for repeated processing, wasting time and energy.

[0004] For example, a Chinese invention patent with publication number CN115742619A discloses an irregular round sculpture processing technology. The technology determines the engraving graphic boundary and engraving path for different irregular objects and converts them into data. The graphic layout, engraving path and engraving depth data are imported into the engraving machine for engraving. Although this method can complete the processing of irregular models, it needs to set different engraving paths according to different irregular models and convert them into data, which is not only costly but also inefficient.

[0005] For example, the Chinese invention patent with publication number CN104028640A discloses a processing technology for a speaker basin frame with an irregular elliptical frame, including a series of steps of cutting - blanking - punching positioning holes and stretching - punching and trimming - punching ear flowers - punching single flowers - punching air holes - back edge punching ribs. The invention adopts the form of multiple single punching assembly line operations to accurately control the size of each blank, but its processing steps are numerous, and the corresponding machines used for multiple processing are large, which is not only inefficient but also costly. Summary of the invention

[0006] In order to solve the above-mentioned technical problems, the present invention provides an irregular model processing technology, and the technical solution is as follows:

[0007] An irregular model processing process comprises the following steps:

[0008] S1: Prepare components and base 1, and open a positioning on base 1;

[0009] S2: During processing, the base bracket 1 is first fixed on the processing platform of the lathe for processing. After the base bracket 1 is processed, an isolation agent is applied to the position of the corresponding component on the upper part of the base bracket 1. After applying the isolation agent, gypsum is poured on the position of the corresponding component;

[0010] S3: After the plaster is shaped, it is processed. After the processing is completed, the component and the base are separated.

[0011] It can effectively improve the processing accuracy of components and reduce burrs and unevenness at the junction of the front and bottom surfaces of the components after processing.

[0012] Preferably, the positioning is a depression or a protrusion corresponding to the shape of the component, and the component fits tightly with the base through the positioning.

[0013] Preferably, the top surface of the base bracket 1 is the bottom surface of the component, and the two are completely consistent with each other, and the surrounding surface of the base bracket 1 is a natural extension of the front surfaces of the component.

[0014] Preferably, when the process is applied to a four-axis CNC machine tool, attention should be paid to the placement direction of the components so that the front sides of the components and the base are both positive mold openings.

[0015] When this process is applied to a four-axis CNC machine tool, it can not only solve the problem that components cannot be fixed, but also does not require flipping the components. It only requires one tool adjustment, which improves the processing accuracy and realizes the processing of irregular components.

[0016] Preferably, it also includes a movable block in the pot and a bottom support 2. When the present process is used to process the movable block in the pot, multiple movable blocks in the pot can be placed on one or more bottom supports 2 for processing. After processing, each movable block needs to be tightly assembled together.

[0017] Preferably, it also includes a groove and a radiator cover convex fan. When the present process is applied to process a groove with a narrow width, the base three is made according to the radiator cover convex fan with a groove on the top surface, and a radiator cover convexity opposite to the groove is provided on the base three.

[0018] Preferably, the top surface of the convex fan of the water tank cover matches the top surface of the bottom bracket three, and the two are completely consistent.

[0019] Preferably, the groove and the protrusion of the water tank cover are of the same size and have corresponding positions.

[0020] Preferably, the water tank mould further comprises a convex fan and a bottom support four, and a depression is formed on the top of the convex fan of the water tank mould.

[0021] Preferably, the size and shape of the base four are the same as the size and shape of the recess.

[0022] When this process is used to process the movable blocks inside the pot, the gaps between the combined movable blocks are small and they can be put into use online after simple trimming. The application of this process can reduce the number of tool adjustments and improve the processing accuracy. When this process is used to process high-height workpieces with deep depressions inside, the waste materials that are turned off are scattered around and will not affect the continued processing, thereby reducing the loss of processing tools and achieving high processing accuracy.

[0023] Beneficial effects:

[0024] The beneficial effects produced by the technical solution of the present invention are as follows:

[0025] 1. This irregular model processing technology can effectively improve the processing accuracy of components and reduce the burrs and unevenness at the junction of the front and bottom surfaces of the components after processing. When this process is applied to a four-axis CNC machine tool, it can not only solve the problem that the components cannot be fixed, but also does not require the components to be flipped. Only one tool adjustment is required, which improves the processing accuracy and realizes the processing of irregular components.

[0026] 2. This irregular model processing technology, when using this technology to process the live blocks in the pot, the gap between the combined live blocks is small, and they can be put into use after simple trimming. The application of this technology can reduce the number of tool adjustments, improve the processing accuracy, make the processed live blocks more accurate, reduce the model assembly time, and improve the model processing and assembly efficiency. When this process is used to process a workpiece with a high height and a deep depression inside, the waste material that is turned off is scattered around, which will not affect the continued processing, reduce the loss of processing tools, and have high processing accuracy.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-2 As shown, an irregular model processing process includes the following steps:

[0039] S1: Prepare component 1 and base 2, and open positioning 3 on base 2;

[0040] S2: During processing, the base bracket 2 is first fixed on the processing platform of the lathe for processing. After the processing of the base bracket 2 is completed, the isolation agent is applied to the position of the upper part of the base bracket 2 corresponding to the component 1, and after applying the isolation agent, gypsum is poured on the position corresponding to the component 1;

[0041] S3: After the plaster is shaped, it is processed. After the processing is completed, the component 1 and the base 2 are separated.

[0042] Specifically, the positioning 3 is a depression or protrusion corresponding to the shape of the component 1. The component 1 fits tightly with the base 2 through the positioning 3. The top surface of the base 2 is the bottom surface of the component 1, and the two are completely consistent. The surrounding surface of the base 2 is a natural extension of the front surfaces of the component 1.

[0043] In addition, when this process is applied to a four-axis CNC machine tool, attention needs to be paid to the placement direction of the component 1 so that the front sides of the component 1 and the base 2 are both positive mold openings.

[0044] In this embodiment, the processing accuracy of the component 1 can be effectively improved, and the burrs and unevenness at the junction of the front and bottom surfaces of the component 1 after processing can be reduced. When this process is applied to a four-axis CNC machine tool, it can not only solve the problem that the component cannot be fixed, but also does not need to be flipped over. Only one tool adjustment is required, which improves the processing accuracy and realizes the processing of irregular components.

[0045] like Figure 3-4 As shown, it also includes a live block 4 in the pot and a bottom support 5. When the present process is used to process the live block 4 in the pot, multiple live blocks 4 in the pot can be placed on one or more bottom supports 5 for processing. Usually, they are placed on one bottom support 4, which reduces the multiple tool alignment and bottom support 4 fixing steps caused by multiple bottom supports 4. After processing, each live block 4 needs to be tightly assembled together.

[0046] In this embodiment, when this process is applied to process the movable block 4 in the pot, the gap between the combined movable blocks is small, and it can be put into use online after simple trimming. The application of this process can reduce the number of tool adjustments, improve the processing accuracy, make the processed movable blocks more accurate, reduce the model assembly time, and improve the model processing and assembly efficiency.

[0047] like Figure 5-6 As shown, it also includes a groove 6 and a water tank cover convex fan 7. When this process is used to process a groove with a narrow width, a base three 8 is made according to the water tank cover convex fan 7 with the groove 6 on the top surface, and a water tank cover protrusion 9 opposite to the groove 6 is provided on the base three 8. The top surface of the water tank cover convex fan 7 is matched with the top surface of the base three 8, and the two are completely consistent. The groove 6 and the water tank cover protrusion 9 are the same size and the positions correspond to each other.

[0048] In this embodiment, the application of this process can reduce the number of tool adjustments, improve processing accuracy, make the processed live blocks more accurate, reduce the model assembly time, and improve the model processing and assembly efficiency.

[0049] like Figure 7-8 As shown, the water tank mold also includes a convex fan 10 and a bottom bracket 12. The top of the convex fan 10 of the water tank mold is provided with a recess 11, and the size and shape of the bottom bracket 12 are the same as the size and shape of the recess 11.

[0050] In this embodiment, when this process is applied to process a workpiece with a high height and a deep depression inside, the waste material that is turned off is scattered around and will not affect the continued processing, thereby reducing the wear of the processing tool and achieving high processing accuracy.

[0051] Example:

[0052] like Figure 1 and Figure 2 As shown in , the base 2 fits tightly with the component 1. By fixing the base 2 on the processing platform, the base 2 has corresponding grooves or protrusions as positioning 3, so that the component 1 can be firmly fixed on the base 2 to avoid errors caused by the movement of the component 1. The front of the base 2 is the bottom of the component 1, and the two are completely consistent. The surrounding surface of the base 2 is a natural extension of the front surfaces of the component 1, so that the curvature of the surrounding surface of the base 2 is consistent with the curvature of the front surfaces of the component 1, which improves the processing accuracy of the component 1 and reduces the burrs and unevenness at the junction of the front and bottom surfaces of the component 1 after processing. The positioning 3 can be a groove or protrusion on the irregular component 1, located on the back of the component 1. If the back of the component 1 is flat, a semicircular or square protrusion can be added to the back for positioning.

[0053] During processing, first fix the base 2 on the processing platform of the lathe for processing. After the processing of the base 2 is completed, brush the isolation agent on the upper part of the base 2 corresponding to the component 1. After brushing the isolation agent, pour gypsum on the corresponding component 1 position. After the gypsum is shaped, it is processed. After the processing is completed, the component 1 and the base 2 can be separated.

[0054] When this process is applied to a four-axis CNC machine tool, since the four-axis CNC machine tool can only process in three directions, the tool cannot be tilted. When processing complex components, the components need to be flipped, and multiple positioning and tool setting are required. The tool setting accuracy cannot be guaranteed. When designing the base 2, attention should be paid to the placement direction of component 1, so that the front of component 1 is a positive mold opening, and the front of the base 2 is also a positive mold opening, to ensure that the component can be processed in place and can be smoothly separated from the base 2 after the processing of component 1 is completed.

[0055] The application of this process can not only solve the problem that components cannot be fixed, but also does not require flipping the components. Only one tool adjustment is required, which improves the processing accuracy and realizes the processing of irregular components.

[0056] When this process is used to process the live block 4 in the pot, Figure 3 As shown, the pot block 4 is placed on one or more bottom brackets 5 for processing. After processing, the pot block is assembled on the ring plate. Figure 4 , each movable block needs to fit tightly together. Before the application of this process, the precision of the pot movable blocks processed was poor, and the various parts could not fit together. After assembly, there were often relatively large gaps and height differences between the movable blocks, which affected the thickness and quality of the wet blank during use. After the application of this process, the gaps between the combined movable blocks are small, and they can be put into use online after simple trimming. The application of this process can reduce the number of tool setting times, improve processing accuracy, make the processed movable blocks more accurate, reduce the model assembly time, and improve the model processing and assembly efficiency.

[0057] When this process is used to process narrow grooves, such as Figure 5 As shown, since there is a groove 6 of the water tank rib on the radiator cover convex fan, and since the minimum diameter of the processing tool is 6mm, for the radiator cover convex fan 7 with a groove 6 less than 6mm in width on the surface, a base bracket three 8 is made. Since the front of the base bracket three 8 is the bottom surface of the radiator cover convex fan 7, the two are completely consistent, and the groove 6 of the radiator cover convex fan 7 is the radiator cover protrusion 9 on the base bracket three 8, which can be processed by a tool with a diameter of 6mm.

[0058] When this process is used to process workpieces with high height and deep internal depressions (depth ≥ 200mm), Figure 7 The convex fan 10 of the water tank mold has waste materials generated during the processing accumulated in the depression 11, which increases the resistance around the processing tool, making it impossible to add the bottom of the workpiece depression in place, resulting in a thicker thickness at the workpiece depression and low processing accuracy. When the process is used to make the workpiece bottom bracket 4 12, the waste materials that fall off during the processing of the bottom bracket are scattered around, which will not affect the continued processing, reduce the loss of the processing tool, and have high processing accuracy.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
