Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile mold processing, and in particular relates to a slow-wire variable taper processing technology for aluminum profile molds. Background Art

[0002] As an advanced mold processing method, the slow-wire variable taper processing technology has been applied to aluminum profile production. The slow-wire variable taper processing technology of aluminum profile mold uses slow-wire wire cutting technology to control the taper of the wire electrode to achieve taper cutting of the mold cavity. This processing method has the advantages of high processing accuracy, fast cutting speed, and long mold life. However, it is also prone to burr problems. The burr is mainly a kind of excess metal residue produced on the cutting edge due to the plastic deformation of the material during the cutting process. At present, in order to improve the quality of slow-wire variable taper processing of aluminum profile molds and ensure green environmental protection, ultrasonic deburring is often used to remove burrs from aluminum profile molds. The specific ultrasonic deburring uses the high-frequency vibration of ultrasound to transfer energy to the burr, causing it to vibrate and break, thereby removing the burr. This method is environmentally friendly and green, and has little damage to the material surface.

[0003] However, there are also some problems with the deburring method in the current aluminum profile mold slow-feeding and variable taper processing technology: in the aluminum profile mold slow-feeding and variable taper processing process, when encountering small gaps, narrow grooves and other difficult-to-process areas of the aluminum profile mold, the metal fluidity in this area will be greatly affected due to space limitations, resulting in uneven metal flow. This uneven flow is likely to form local high pressure and speed in these areas of the mold, causing metal to accumulate in these places, thereby generating larger burrs. At this time, when ultrasonic high-frequency vibration is used to remove burrs, the ultrasonic high-frequency vibration will not only act on the area where the burr is located during the propagation process, but may also propagate through the mold material to the area where the burr has been removed. Since the aluminum profile mold itself has a certain elasticity, the vibration wave may cause the material in other areas to also produce small vibrations during the propagation process, thereby affecting the processing accuracy of the area where the burr has been removed. In this regard, an aluminum profile mold slow-feeding and variable taper processing technology is proposed. Summary of the invention

[0004] In order to solve the above-mentioned problems existing in the prior art, the present invention provides an aluminum profile mold slow-feed wire variable taper processing technology for removing burrs, which solves the problem that in the aluminum profile mold slow-feed wire variable taper processing technology of the prior art, the high-frequency vibration of the ultrasonic wave may be transmitted through the mold material to the area where the burrs have been removed, thereby affecting the processing accuracy of the area where the burrs have been removed.

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

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

[0007] S1: According to the mold design drawing, set the cutting path and parameters, select the appropriate electrode wire diameter, and then install the electrode wire on the slow-wire wire cutting machine. According to the material type, thickness and required taper, set the cutting speed, current, water pressure and other parameters;

[0008] S2: In the design stage, the height difference of the discharge surface and the length of the working belt are determined according to the design requirements of the mold;

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

[0010] S4: Cone cutting stage, the cutting program is started, and the wire cutting machine 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, electrode wire diameter and processing conditions, and set a constant tension device between the wire feed wheel and the wire guide wheel of the electrode wire to prevent local overheating of the aluminum profile;

[0012] S6: Deburring treatment: along the mold core curve of the aluminum profile mold, the straight line part and the part approximately in the straight line are defined as the easy processing area, the part connected between the straight line part and the part connected between the straight line part and the approximately straight line part are defined as the medium processing area, and the rest are defined as the difficult processing area.

[0013] Deburring of difficult-to-process areas: first start from the two ends of the difficult-to-process area and slowly move toward the center to deburr the difficult-to-process area; Deburring of medium-to-process areas: after the difficult-to-process area is processed, use a method faster than the difficult-to-process area to evenly move from one end of the medium-to-process area to deburr the medium-to-process area; Deburring of easy-to-process areas: after the medium-to-process area is processed, use a method faster than the medium-to-process area to evenly move from one end of the easy-to-process area to the other end, thereby reducing the impact of vibration on the processing accuracy of the deburred area.

[0014] As a further solution of the present invention, in the deburring process for the medium processing area and the easy processing area in S6, the moving direction of the burrs is consistent with the direction of material removal.

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

[0016] As a further solution of the present invention, when removing burrs from the medium processing area in S6, ultrasonic equipment is used for processing, and it is necessary to apply a certain force to the deburring medium and then evenly act on the surface of the workpiece and then move evenly.

[0017] As a further solution of the present invention, when removing burrs from the easy-to-process area in S6, ultrasonic equipment is used for processing, and the deburring medium needs to be gently applied to the surface of the workpiece and then moved evenly.

[0018] As a further solution of the present invention, there are multiple difficult-to-process areas, medium-to-process areas and easy-to-process areas in S6. When processing the multiple difficult-to-process areas, medium-to-process areas and easy-to-process areas separately, they are processed in order from large to small, starting from the areas with larger areas and gradually transitioning to the areas with smaller areas.

[0019] As a further solution of the present invention, a vibration-damping material for absorbing part of the vibration energy is arranged between the ultrasonic equipment and the aluminum profile mold.

[0020] As a further solution of the present invention, the constant tension device includes a tension sensor and a drive motor. The tension sensor is externally connected to a control system, which determines a suitable initial tension value according to the processing material, electrode wire diameter and processing conditions. The tension sensor monitors the real-time tension of the electrode wire. The control system continuously receives feedback signals from the tension sensor and compares them with a preset tension value. If a tension change is detected, when the tension deviates from the preset value, the control system sends a signal to the drive motor, and the drive motor adjusts the rotation speed or spacing of the wire feed wheel and the wire guide wheel to restore the tension of the electrode wire to the preset value.

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

[0022] By calculating the specific parameters of the 2.5-degree obstruction angle that needs to be made at the half position of the working strip length of the inlet surface, and then programming the calculated obstruction angle parameters into the wire cutting program, the programmed wire cutting program is input into the wire cutting machine, and the cutting program is started. The wire cutting machine cuts the obstruction angle according to the wire cutting program, and sets the obstruction angle according to the wall thickness of the profile. The obstruction angle is different for different wall thicknesses, thereby achieving the effect of controlling the aluminum flow speed, guiding the material to flow more evenly inside the mold, and allowing the various parts of the aluminum profile to be fully welded in the mold. More importantly, the density of the aluminum profile is higher and the surface quality is better. By setting an obstruction angle with specific parameters on the inlet surface of the aluminum profile mold, the aluminum flow speed 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 mold and increase the flow resistance. When the aluminum liquid passes through the obstruction angle, its speed will be reduced due to obstruction, thereby controlling the flow rate of the aluminum liquid.

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1 - Figure 4 This embodiment provides a slow-wire variable taper processing process for aluminum profile molds, comprising the following steps:

[0032] S1: According to the mold design drawing, set the cutting path and parameters, select the appropriate electrode wire diameter, and then install the electrode wire on the slow-feed wire cutting machine. According to the material type, thickness and required taper, set the cutting speed, current, water pressure and other parameters 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 of the discharge surface and the length of the working belt, provide accurate data basis for subsequent programming and cutting, and ensure the discharge performance and processing accuracy of the mold;

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

[0035] S4: In the variable taper cutting stage, the cutting program is started, and the wire cutting machine cuts 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 the obstruction angle is different for different wall thicknesses, thereby achieving the effect of controlling the aluminum flow speed, allowing the various parts of the aluminum profile to be fully welded in the mold, and more importantly, making the density of the aluminum profile higher and the surface quality better, avoiding the hollow aluminum profile phenomenon; in addition, 2.5 degrees is a relatively small angle, which can have a certain obstruction effect on the flow of aluminum liquid, but will not excessively affect the fluidity of aluminum liquid, and maintain the stability of the pressure in the mold. This angle is based on long-term practical experience and can meet the production needs of most aluminum profiles; in addition, setting the obstruction angle helps to maintain the stability of the profile size, so that the size of the produced aluminum profile products is more accurate and the surface quality is higher;

[0036] One point that needs to be supplemented is that by setting an obstruction angle with specific parameters on the inlet surface of the aluminum profile mold, the aluminum flow speed 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 aluminum liquid inside the mold and increase the flow resistance. When the aluminum liquid passes through the obstruction angle, its speed will be reduced due to obstruction, thereby controlling the flow rate of the aluminum liquid. The obstruction angle design can form a streamline, which helps to reduce eddy currents and turbulence, making the aluminum liquid flow more smoothly and avoiding local overheating or splashing caused by excessive speed. The obstruction angle can guide the aluminum liquid to flow along a predetermined path, avoiding local flow velocity differences caused by sudden changes in flow direction, thereby achieving more uniform flow. By designing obstruction angles with different wall thicknesses, the flow resistance of different parts can be adjusted, so that the flow velocity of the aluminum liquid in various places inside the mold is consistent, achieving uniform flow, and the obstruction angle prolongs the flow time of the aluminum liquid inside the mold, which is conducive to full contact and welding between the aluminum liquid parts, and also helps to optimize the temperature distribution inside the mold, so that the aluminum liquid maintains a suitable temperature during the entire flow process, which is conducive to the welding process.

[0037] In addition, uniform flow and sufficient welding help reduce pores and inclusions in the aluminum liquid and increase the density of the profile. The obstruction angle design helps reduce turbulence and eddy currents, making the aluminum liquid flow more smoothly, thereby reducing surface defects and improving surface quality. Reasonable obstruction angle design can also control the cooling rate of the aluminum liquid, help maintain the uniformity of the internal structure of the material, and further improve the mechanical properties and surface quality of the profile.

[0038] S5: Roughness control. The appropriate tension value is determined according to the processing material, electrode wire diameter and processing conditions. A constant tension device is set between the wire feed 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 the cutting process, reduce the cutting error caused by tension changes, and improve the cutting surface quality.

[0039] S6: Deburring treatment. First, the mold core curve of the aluminum profile mold targeted by this application is an irregular ring. Along the mold core curve of the aluminum profile mold, the straight line part and the approximate straight line part are delineated as the easy processing area, the part connected between the straight line part and the part connected between the straight line part and the approximate straight line part are the medium processing area, and the rest are the difficult processing areas, such as Figure 2 - Figure 4 As shown, for deburring the difficult-to-process area: first start from the two ends of the difficult-to-process area and slowly move toward the center to deburr the difficult-to-process area; for deburring the medium-to-process area: after the difficult-to-process area is processed, use a method faster than the difficult-to-process area to evenly move from one end of the medium-to-process area to deburr the medium-to-process area; for deburring the easy-to-process area: after the medium-to-process area is processed, use a method faster than the medium-to-process area to evenly move from one end of the easy-to-process area to the other end, thereby reducing the vibration from The processing accuracy of the deburred area;

[0040] One thing that needs to be explained is that in the deburring process, if the burrs in the medium or difficult-to-process areas are processed first, and then the easy-to-process areas are processed, the surface quality of the easy-to-process areas may be reduced, because the equipment may generate vibrations when processing the difficult-to-process areas, affecting the processing accuracy. Therefore, the difficult-to-process areas are processed first here. Since the difficult-to-process areas have a greater impact on the propagation of vibration waves, priority processing can reduce the propagation of vibration waves in subsequent processing. Secondly, the medium processing areas are processed. After the difficult-to-process areas are processed, the medium processing areas are deburred. At this time, the difficult-to-process areas of the mold have been stabilized, and the vibration impact of the medium processing areas will be relatively small. Finally, the easy-to-process areas are processed. The easy-to-process areas usually have the least impact on vibration waves and can be processed last. This can minimize the propagation of vibration waves to other areas, thereby protecting the processing accuracy.

[0041] At present, ultrasonic deburring is usually used to remove burrs from aluminum profile molds in the process of wire-cut variable taper machining for aluminum profile molds. There are some problems with ultrasonic deburring in the process of wire-cut variable taper machining for aluminum profile molds. For example, in the process of wire-cut variable taper machining for aluminum profile molds, when encountering difficult-to-process areas such as small gaps and narrow grooves of the aluminum profile mold, the metal fluidity in this area will be greatly affected due to space limitations, resulting in uneven metal flow. This uneven flow is likely to form local high pressure and speed in these areas of the mold, causing metal to accumulate in these places, thereby generating larger burrs. At this time, when ultrasonic high-frequency vibration is used to remove burrs, the ultrasonic high-frequency vibration will not only act on the area where the burr is located during the propagation process, but may also propagate through the mold material to the area where the burr has been removed. Since the aluminum profile mold itself has a certain elasticity, the vibration wave may cause the material in other areas to also produce small vibrations during the propagation process, thereby affecting the processing accuracy of the area where the burr has been removed.

[0042] In order to solve the above problems, in this embodiment, the mold core of the aluminum profile mold is divided into different areas along the mold core curve, and the straight line part and the approximate straight line part are defined as the easy processing area, the part connecting the straight line part and the part connecting the straight line part and the approximate straight line part are the medium processing area, and the rest are the difficult processing area. The difficult processing area is deburred: first, start from the two end edges of the difficult processing area and slowly move toward the center to deburr the difficult processing area; deburr the medium processing area: after the difficult processing area is processed, use a method faster than the difficult processing area to evenly move from one end of the medium processing area to the other end to deburr the medium processing area; deburr the easy processing area: after the medium processing area is processed, use a method faster than the medium processing area to evenly move from one end of the easy processing area to the other end. Through this strategy of dividing the area and optimizing the processing sequence, the influence of the vibration wave on other areas during the ultrasonic deburring process can be effectively reduced, thereby improving the processing accuracy and ensuring the quality of mold processing.

[0043] In order to ensure the processing quality and improve the efficiency at the same time, in one embodiment, the moving direction of the burrs in the deburring treatment of the medium processing area and the easy processing area in S6 is consistent with the direction of material removal. When the difficult processing area is deburred in S6, most of the burrs are first removed by mechanical methods, and then fine processing is performed using ultrasonic equipment. When the medium processing area is deburred in S6, ultrasonic equipment is used for processing, and it is necessary to apply a certain force to the deburring medium and then evenly act on the surface of the workpiece and then move evenly. When the easy processing area is deburred in S6, ultrasonic equipment is used for processing, and it is necessary to gently act on the surface of the workpiece and then move evenly. For the medium processing area and the easy processing area, the deburring moving direction is consistent with the material removal direction, which helps to reduce resistance during processing and improve processing speed and efficiency. Difficult processing areas are usually difficult to remove burrs due to complex shapes or material properties. First use mechanical methods to remove most of the burrs, which can quickly reduce the size of the burrs and create conditions for subsequent ultrasonic fine processing. Use ultrasonic equipment to deburr the medium processing area. By applying a certain force to make the deburring medium act evenly on the workpiece surface and then move evenly, you can ensure the uniformity and meticulousness of the deburring and reduce damage to the workpiece surface. For easy-to-process areas, gently act on the workpiece surface to avoid excessive processing and protect the accuracy and integrity of the workpiece surface.

[0044] In addition, when deburring is performed again, since there are not only one difficult-to-process area, medium-to-process area and easy-to-process area, but multiple identical areas, and the areas of multiple identical areas are not exactly the same, and the area with a larger area will contain more burrs, which requires more time to process. In order to further avoid reducing the impact of vibration waves on the area where the burrs have been removed during the ultrasonic deburring process, in this regard, in one embodiment, the number of difficult-to-process areas, medium-to-process areas and easy-to-process areas in S6 is multiple. When processing multiple difficult-to-process areas, medium-to-process areas and easy-to-process areas separately, they are processed in order from large to small, starting from the area with a larger area and gradually transitioning to the area with a smaller area. During the processing of large-area areas, the amount of material removed is large and vibration is easy to occur. Processing these areas first can gradually stabilize the workpiece and reduce vibration and deformation during the subsequent processing of small-area areas. The processing order from large areas to small areas is conducive to maintaining the processing accuracy of the workpiece. After processing a large area, the overall shape and size of the workpiece have been basically determined. Then processing a small area can more easily achieve the required accuracy requirements. In addition, the processing order from large to small helps to timely discover and deal with quality problems during the processing. When processing a 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 ultrasonic equipment, further reduce the impact of vibration waves on other areas during ultrasonic deburring, and improve processing accuracy, in one embodiment, a vibration-damping material for absorbing part of the vibration energy is provided between the ultrasonic equipment 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 impact of vibration waves on processing accuracy.

[0046] In the processing of aluminum profile molds, the tension of the electrode wire is easily affected by various factors in the wire feeding and wire guiding processes, resulting in unstable tension. In the slow wire feeding processing of aluminum profiles, local overheating may cause changes in material properties and cause vibration or relaxation of the electrode wire. The local overheating of the electrode wire caused by vibration or relaxation affects the smoothness and dimensional accuracy of the cutting surface. In order to solve this problem, in one embodiment, the constant tension device includes a tension sensor and a drive motor. The tension sensor is externally connected to a control system. According to the processing material, the electrode wire diameter 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, when the tension deviates from the preset value, the control system will send a signal to the drive motor, and the drive 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 description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
