Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum profile die processing, and particularly relates to a slow wire cutting taper processing technology for aluminum profile dies. Background Art

[0002] As an advanced die processing method, the slow wire cutting taper processing technology has been applied to aluminum profile production. The slow wire cutting taper processing technology for aluminum profile dies utilizes the slow wire electrical discharge machining technology. By controlling the taper of the wire electrode, the taper cutting of the die cavity is achieved. This processing method has the advantages of high machining accuracy, fast cutting speed, long die life, etc. However, burr problems are likely to occur at the same time. Burrs are mainly redundant metal residues generated at the cutting edge due to plastic deformation of the material during the cutting process. At present, in order to improve the quality of slow wire cutting taper processing of aluminum profile dies and ensure environmental protection at the same time, the ultrasonic deburring method is often used to remove the burrs of aluminum profile dies. The specific ultrasonic deburring is to utilize the high-frequency vibration of ultrasonic waves to transfer energy to the burrs, make them vibrate and break, so as to remove the burrs. This method is environmentally friendly, green, and has little damage to the material surface.

[0003] However, there are also some problems with the current deburring method in the slow wire cutting taper processing technology for aluminum profile dies: during the slow wire cutting taper processing of aluminum profile dies, when encountering difficult-to-process areas such as micro gaps and narrow grooves in the aluminum profile dies, due to space limitations in this area, the metal fluidity will be greatly affected, resulting in unsmooth metal flow. This uneven flow is likely to form local high pressures and speeds in these areas of the die, causing the metal to accumulate in these places, thus generating larger burrs. At this time, when using the high-frequency vibration of ultrasonic waves to remove the burrs, during the propagation of the high-frequency vibration of ultrasonic waves, it will not only act on the area where the burrs are located, but may also be transmitted to the area where the burrs have been removed through the die material. And due to the certain elasticity of the aluminum profile die itself, the vibration waves may cause the materials in other areas to also have slight vibrations during the propagation process, thus affecting the machining accuracy of the area where the burrs have been removed. In view of this, the slow wire cutting taper processing technology for aluminum profile dies is proposed. Summary of the Invention

[0004] To solve the above problems existing in the prior art, the present invention provides a slow wire cutting taper processing technology for aluminum profile dies to remove burrs, solving the problem that in the slow wire cutting taper processing technology for aluminum profile dies in the prior art, the high-frequency vibration of ultrasonic waves may be transmitted to the area where the burrs have been removed through the die material, thus affecting the machining accuracy of the area where the burrs have been removed.

[0005] The object of the present invention can be achieved through the following technical solutions:

[0006] The slow wire cutting taper processing technology for aluminum profile dies includes the following steps:

[0007] S1: According to the die design drawing, set the cutting path and parameters, select the appropriate diameter of the electrode wire, then install the electrode wire on the slow wire cutting machine tool, and set parameters such as cutting speed, current, and water pressure according to the material type, thickness, and required taper.

[0008] S2: In the design stage, according to the design requirements of the die, determine the height difference between the high and low points of the discharge surface and the length of the working belt.

[0009] S3: In the programming stage, according to the design requirements, calculate the specific parameters of the 2.5-degree obstruction angle that needs to be made at half of the length of the working belt on the inlet surface, then compile the calculated obstruction angle parameters into the wire cutting program, and then input the compiled wire cutting program into the slow wire cutting machine tool.

[0010] S4: In the variable taper cutting stage, start the cutting program, and the slow wire cutting machine tool cuts out the obstruction angle according to the wire cutting program.

[0011] S5: Roughness control, determine the appropriate tension value according to the processing material, diameter of the electrode wire, and processing conditions, and set a constant tension device between the wire supply wheel and the wire guide wheel of the electrode wire to prevent local overheating of the aluminum profile.

[0012] S6: Burr removal treatment, along the curve of the die core of the aluminum profile die, demarcate the straight part and the approximately straight part as the easy processing area, the part connecting the straight part to the straight part and the part connecting the straight part to the approximately straight part as the medium processing area, and the rest as the difficult processing area.

[0013] Burr removal treatment for the difficult processing area: First, start from the two end edges of the difficult processing area and slowly move towards the center to remove burrs from the difficult processing area; Burr removal treatment for the medium processing area: After the difficult processing area is processed, then use a method faster than that of the difficult processing area to move evenly from one end to the other end of the medium processing area to remove burrs from the medium processing area; Burr removal treatment for the easy processing area: After the medium processing area is processed, use a method faster than that of the medium processing area to move evenly from one end to the other end of the easy processing area, reducing the vibration's impact on the processing accuracy of the area where burrs have been removed.

[0014] As a further solution of the present invention, in S6, the moving direction of removing burrs from the medium processing area and the easy processing area is the same as the direction of material removal.

[0015] As a further solution of the present invention, when removing burrs from the difficult processing area in S6, first use a mechanical method to remove most of the burrs, and then use an ultrasonic device for fine processing.

[0016] As a further solution of the present invention, when deburring the medium processing area in S6, an ultrasonic device is used for processing. It is necessary to apply a certain force to the deburring medium and then uniformly act on the surface of the workpiece and then move uniformly.

[0017] As a further solution of the present invention, when deburring the easy processing area in S6, an ultrasonic device is used for processing. It is necessary to gently act on the surface of the workpiece with the deburring medium and then move uniformly.

[0018] As a further solution of the present invention, the numbers of the difficult processing area, medium processing area and easy processing area in S6 are multiple. When processing multiple difficult processing areas, medium processing areas and easy processing areas respectively, in the order from large to small, start from the area with a larger area first and gradually transition to the area with a smaller area.

[0019] As a further solution of the present invention, a damping material for absorbing part of the vibration energy is provided between the ultrasonic device and the aluminum profile die.

[0020] As a further solution of the present invention, the constant tension device includes a tension sensor and a driving motor. The tension sensor is externally connected to a control system. According to the processing material, the diameter of the electrode wire and the processing conditions, a suitable initial tension value is determined. The tension sensor monitors the real-time tension of the electrode wire. The control system continuously receives the feedback signal of the tension sensor and compares it with the preset tension value. If a tension change is detected and the tension deviates from the preset value, the control system will send a signal to the driving motor, and the driving motor adjusts the rotation speed or spacing of the wire feeding wheel and the wire guiding wheel to restore the tension of the electrode wire to the preset value.

[0021] The beneficial effects of the present invention are as follows:

[0022] By calculating the specific parameters of the 2.5-degree obstruction angle that need to be made at half of the working belt length at the inlet surface, then incorporating the calculated obstruction angle parameters into the wire cutting program, and then inputting the compiled wire cutting program into the slow wire cutting machine tool, starting the cutting program, the slow wire cutting machine tool cuts out the obstruction angle according to the wire cutting program. The obstruction angle is set according to the wall thickness of the profile, and different wall thicknesses have different obstruction angles, so as to achieve the effect of controlling the aluminum flow rate, guiding the material to flow more evenly inside the die, enabling all parts of the aluminum profile to be fully welded in the die, and more importantly, making the aluminum profile have a higher density and better surface quality. By setting an obstruction angle with specific parameters at the inlet surface of the aluminum profile die, the aluminum flow rate and the flow behavior of the material can be effectively controlled. The design of the obstruction angle can change the flow path of the aluminum liquid inside the die, increase the flow resistance, and when the aluminum liquid passes through the obstruction angle, its speed will be reduced due to the obstruction, thereby controlling the flow rate of the aluminum liquid.

[0030] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, explain in detail the specific embodiments, structures, features and their effects according to the present invention.

[0031] Please refer to Figure 1 - Figure 4 , this embodiment provides a slow wire cutting variable taper machining process for aluminum profile molds, including the following steps:

[0032] S1: According to the mold design drawing, set the cutting path and parameters, select a suitable electrode wire diameter, then install the electrode wire on the slow wire cutting machine tool, and set parameters such as cutting speed, current, and water pressure according to the material type, thickness, and required taper to ensure that the cutting process meets the design requirements, improve cutting efficiency and accuracy, and reduce material waste and processing costs;

[0033] S2: In the design stage, according to the design requirements of the mold, determine the height difference between the high and low points of the discharge surface and the length of the working belt to provide an accurate data basis for subsequent programming and cutting, and ensure the discharge performance and machining accuracy of the mold;

[0034] S3: In the programming stage, according to the design requirements, calculate the specific parameters of the 2.5-degree obstruction angle that needs to be made at half of the length of the working belt on the inlet surface, then incorporate the calculated obstruction angle parameters into the wire cutting program, and then input the compiled wire cutting program into the slow wire cutting machine tool;

[0035] S4: In the variable taper cutting stage, start the cutting program. The slow wire cutting machine cuts out the obstruction angle according to the wire cutting program. The purpose of S2 - S4 is to set the obstruction angle according to the wall thickness of the profile, so that different wall thicknesses result in different obstruction angles, thereby achieving the effect of controlling the aluminum flow rate, enabling all parts of the aluminum profile to be fully welded in the mold. More importantly, it makes the aluminum profile have a higher density and better surface quality, and avoids the appearance of hollow aluminum profiles. In addition, 2.5 degrees is a relatively small angle that can both have a certain obstructive effect on the flow of molten aluminum and not overly affect the fluidity of the molten aluminum, maintaining the stability of the pressure inside the mold. This angle is obtained based on long - term practical experience and can meet the production requirements of most aluminum profiles. In addition, setting the obstruction angle helps to maintain the dimensional stability of the profile, making the size of the produced aluminum profile products more accurate and the surface quality higher.

[0036] It should be added that by setting an obstruction angle with specific parameters on the inlet surface of the aluminum profile mold, the aluminum flow rate and the flow behavior of the material can be effectively controlled. Among them, the design of the obstruction angle can change the flow path of the molten aluminum inside the mold, increasing the flow resistance. When the molten aluminum passes through the obstruction angle, its speed will decrease due to the obstruction, thus controlling the flow rate of the molten aluminum. The design of the obstruction angle can form a streamline shape, helping to reduce eddies and turbulence, making the flow of the molten aluminum more stable, and avoiding local overheating or splashing caused by too fast speed. The obstruction angle can guide the molten aluminum to flow along a predetermined path, avoiding local flow rate differences caused by sudden changes in the flow direction, thereby achieving a more uniform flow. Through the design of obstruction angles with different wall thicknesses, the flow resistance of different parts can be adjusted to make the flow rate of the molten aluminum consistent everywhere inside the mold, achieving a uniform flow. And the obstruction angle prolongs the flow time of the molten aluminum inside the mold, which is conducive to the full contact and welding between different parts of the molten aluminum, and also helps to optimize the temperature distribution inside the mold, keeping the molten aluminum at an appropriate temperature throughout the flow process, which is conducive to the welding process.

[0037] In addition, uniform flow and full welding help to reduce pores and inclusions in the molten aluminum, increasing the density of the profile. The design of the obstruction angle helps to reduce turbulence and eddies, making the flow of the molten aluminum more stable, thereby reducing surface defects and improving surface quality. A reasonable design of the obstruction angle can also control the cooling rate of the molten aluminum, helping to maintain the uniformity of the internal structure of the material, and further improving the mechanical properties and surface quality of the profile.

[0038] S5: Roughness control. Determine the appropriate tension value according to the processing material, electrode wire diameter and processing conditions. Set a constant tension device between the wire supply wheel and the wire guide wheel of the electrode wire to prevent local overheating of the aluminum profile. This method can ensure the stability of the electrode wire during cutting, reduce cutting errors caused by tension changes, and improve the cutting surface quality.

[0039] S6: Deburring process. First, the core curve of the aluminum profile die targeted by the present application is an irregular ring. Along the core curve of the aluminum profile die, the straight parts and the parts approximated to straight lines are defined as the easy - processing areas, the parts connecting straight parts to straight parts and the parts connecting straight parts to approximated - straight parts are defined as the medium - processing areas, and the remaining parts are defined as the difficult - processing areas. As shown in Figure 2 - Figure 4 , deburring treatment is carried out on the difficult - processing areas: starting from the two end - edges of the difficult - processing areas and slowly moving towards the center to perform deburring treatment on the difficult - processing areas; deburring treatment is carried out on the medium - processing areas: after the difficult - processing areas are processed, then move uniformly from one end to the other end of the medium - processing areas in a way with a higher speed than that of the difficult - processing areas to perform deburring treatment on the medium - processing areas; deburring treatment is carried out on the easy - processing areas: after the medium - processing areas are processed, move uniformly from one end to the other end of the easy - processing areas in a way with a higher speed than that of the medium - processing areas, reducing the vibration's impact on the machining accuracy of the already deburred areas;

[0040] It should be noted that in the deburring process, if the burrs in the medium - or difficult - processing areas are processed first and then return to the easy - processing areas for processing, it may lead to a reduction in the surface quality of the easy - processing areas because the equipment may generate vibrations when processing the difficult - processing areas, affecting the machining accuracy. Therefore, the difficult - processing areas are processed first here. Since the difficult - processing areas have a greater impact on the propagation of vibration waves, prior treatment can reduce the propagation of vibration waves in the subsequent processing. Secondly, the medium - processing areas are processed. After the difficult - processing areas are processed, deburring is carried out on the medium - processing areas. At this time, the difficult - processing areas of the die have been stabilized, and the vibration impact on the medium - processing areas will be relatively small. Finally, the easy - processing areas are processed. The easy - processing areas usually have the least impact on the vibration waves and can be processed last, which can minimize the propagation of vibration waves to other areas, thus protecting the machining accuracy.

[0041] In the current wire cut taper machining process of aluminum profile dies, the ultrasonic deburring method is usually used to remove the burrs of aluminum profile dies. However, there are some problems with the ultrasonic deburring method in the wire cut taper machining process of aluminum profile dies. For example, during the wire cut taper machining process of aluminum profile dies, when encountering difficult-to-process areas such as tiny gaps and narrow grooves in the aluminum profile dies, due to space limitations in this area, the metal fluidity will be greatly affected, resulting in unsmooth metal flow. This uneven flow is likely to form local high pressures and speeds in these areas of the die, causing the metal to accumulate in these places, thus generating relatively large burrs. At this time, when using the high-frequency vibration of ultrasonic waves to remove the burrs, during the propagation of the high-frequency vibration of ultrasonic waves, it will not only act on the area where the burrs are located, but may also spread to the area where the burrs have been removed through the die material. Since the aluminum profile die itself has a certain elasticity, the vibration wave may cause slight vibrations in the materials of other areas during the propagation process, thus affecting the machining accuracy of the area where the burrs have been removed.

[0042] To solve the above problems, in this embodiment, by following the curve of the die core of the aluminum profile die, the die core of the die is divided into different regions. The straight part and the approximately straight part are defined as the easy-to-process regions, the parts connecting the straight parts and the parts connecting the straight part and the approximately straight part are the medium-processing regions, and the remaining parts are the difficult-to-process regions. Burr removal treatment is carried out on the difficult-to-process regions: starting from the two end edges of the difficult-to-process region and slowly moving towards the center to carry out burr removal treatment on the difficult-to-process region; burr removal treatment on the medium-processing regions: after the difficult-to-process region is processed, then use a method with a faster speed than that of the difficult-to-process region to move uniformly from one end to the other end of the medium-processing region to carry out burr removal treatment on the medium-processing region; burr removal treatment on the easy-to-process regions: after the medium-processing region is processed, use a method with a faster speed than that of the medium-processing region to move uniformly from one end to the other end of the easy-to-process region. Through this strategy of dividing regions and optimizing the processing sequence, the influence of the vibration wave on other regions during the ultrasonic deburring process can be effectively reduced, thereby improving the machining accuracy and ensuring the quality of die machining.

[0043] To ensure the processing quality while improving the efficiency, in one embodiment, during deburring of the medium processing area and the easy processing area in S6, the movement direction of the burr is the same as the material removal direction. When deburring the difficult processing area in S6, most of the burrs are first removed by mechanical methods, and then ultrasonic equipment is used for fine processing. When removing burrs from the medium processing area in S6, ultrasonic equipment is used for processing. The deburring medium needs to be applied with a certain force and then uniformly act on the workpiece surface and then move uniformly. When removing burrs from the easy processing area in S6, ultrasonic equipment is used for processing. The deburring medium needs to gently act on the workpiece surface and then move uniformly. For the medium processing area and the easy processing area, the deburring movement direction is the same as the material removal direction, which helps to reduce the resistance during processing and improve the processing speed and efficiency. Burrs are usually difficult to remove from the difficult processing area due to complex shapes or material properties. First using mechanical methods to remove most of the burrs can quickly reduce the size of the burrs and create conditions for subsequent ultrasonic fine processing. Using ultrasonic equipment for deburring the medium processing area, by applying a certain force to make the deburring medium uniformly act on the workpiece surface and then move uniformly, can ensure the uniformity and meticulousness of deburring and reduce damage to the workpiece surface. For the easy processing area, gently acting on the workpiece surface can avoid overprocessing and protect the accuracy and integrity of the workpiece surface.

[0044] In addition, when performing deburring, since there are not only one difficult processing area, medium processing area, and easy processing area, but multiple identical areas, and the area sizes of the multiple identical areas are not completely the same, and the larger area will contain more burrs and require more time to process. To further avoid reducing the influence of vibration waves on the areas where burrs have been removed during ultrasonic deburring, in one embodiment, the number of difficult processing areas, medium processing areas, and easy processing areas in S6 is multiple. When processing multiple difficult processing areas, medium processing areas, and easy processing areas separately, in the order from large to small, start from the larger area first and gradually transition to the smaller area. During the processing of the large area, the material removal amount is large and vibration is likely to occur. Processing these areas first can make the workpiece gradually stabilize and reduce vibration and deformation during the subsequent processing of small areas. The processing order from large area to small area is beneficial to maintaining the processing accuracy of the workpiece. After processing the large area, the overall shape and size of the workpiece have been basically determined. Then, processing the small area can more easily meet the required accuracy requirements. In addition, the processing order from large to small helps to detect and handle quality problems in a timely manner during processing. When processing the smaller area, it is easier to find problems in the previous processing and make corresponding adjustments.

[0045] In order to further reduce the propagation of vibration waves of the ultrasonic device and further reduce the influence of vibration waves on other areas during the ultrasonic deburring process, and improve the processing accuracy. For this purpose, in one embodiment, a damping material for absorbing part of the vibration energy is provided between the ultrasonic device and the aluminum profile mold to reduce the propagation of vibration waves. During the processing, the mold is properly fixed and supported to reduce the propagation of vibration waves, and the frequency, amplitude and power of the ultrasonic wave are adjusted to reduce the influence of vibration waves on the processing accuracy.

[0046] In the processing of aluminum profile molds, the tension of the electrode wire is easily affected by various factors during the wire feeding and wire guiding processes, resulting in unstable tension. During the slow wire cutting process of aluminum profiles, local overheating may cause changes in material properties, causing the electrode wire to vibrate or slack. The local overheating caused by the vibration or slack of the electrode wire affects the surface finish and dimensional accuracy of the cutting. To solve this problem, in one embodiment, the constant tension device includes a tension sensor and a driving motor. The tension sensor is externally connected to the control system. According to the processing material, the diameter of the electrode wire and the processing conditions, a suitable initial tension value is determined. The tension sensor monitors the real-time tension of the electrode wire. The control system continuously receives the feedback signal from the tension sensor and compares it with the preset tension value. If a change in tension is detected, when the tension deviates from the preset value, the control system sends a signal to the driving motor, and the driving motor adjusts the rotation speed or spacing of the wire feeding wheel and the wire guiding wheel to restore the tension of the electrode wire to the preset value.

[0047] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes. However, as long as it does not depart from the technical content of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
