Description

Technical Field

[0001] The utility model relates to the field of metal composite material processing equipment, in particular to a composite surface forming tool for non-rectangular heterogeneous metal composite materials. Background Art

[0002] Layered metal composite materials are made by combining the composite metal with the base metal through explosive compounding, rolling compounding or other preparation technologies, and the products have typical bonding interface characteristics. On the one hand, this new material can save rare metals and precious metals and reduce the manufacturing cost of downstream equipment; on the other hand, it can improve the thermal expansion, strength, wear resistance and other properties of single metal materials, solve technical problems that single metals cannot solve, and meet the requirements for material performance in special environments such as strong corrosion, high temperature and high pressure.

[0003] Mobile phone screen glass has evolved from early 2D glass to 2.5D glass and now 3D glass. As users demand it, the sides of the phone frame have also evolved from vertical surfaces to 3D surfaces.

[0004] Titanium-aluminum composite series: Titanium is a new type of metal with many excellent properties such as low density, high strength, corrosion resistance and good high and low temperature performance, but it is expensive. Titanium-aluminum composite materials can not only significantly reduce the cost of related equipment. The inner layer of aluminum improves the overall processability and effectively reduces processing time and cost.

[0005] 3D arc profiles have become the mainstream in the mobile phone industry, while titanium-aluminum composite materials are still in the growth stage of rectangular regular cross-section composites. In the existing technology, titanium-aluminum composites are mainly composites between planes, that is, the cross-sections of the aluminum layer material and the titanium layer material are both rectangular structures, such as Figure 1 As shown in FIG. 1 , after the two materials are composited, the composite surface is in the form of a plane. This composite form has poor firmness at the composite surface, and there is a probability of delamination when dealing with lateral stress. The applicant has improved this composite form; that is, two non-rectangular metal substrates are used for composite, specifically as shown in FIG. Figure 2 As shown, one substrate is processed on the composite surface to form a convex cavity, and the other substrate is processed on the composite surface side to form a concave cavity. During the composite process, the area of ​​the composite surface is increased, and the flat composite surface is changed into an arc-shaped composite surface, thereby improving the ability to withstand lateral forces and further improving the physical properties of the composite material. When processing this non-rectangular heterogeneous metal composite material, the composite surfaces of the two metals need to be pre-processed.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] A composite surface forming tool for non-rectangular heterogeneous metal composite materials, such as Figure 3 , 4 As shown, the processing platform 1 includes a profiling device 2, one side of the profiling device 2 is provided with a mold station 3, and the other side is provided with a processing station 4. In actual use, the standard model made according to the design is placed in the mold station 3, and the metal material to be processed is placed in the processing station 4 on the other side. During processing, the device can process aluminum or titanium profiles, which are placed in the processing station 4 and the fixed workpiece is profiled by the profiling device 2, so that the workpiece is formed as shown in FIG. Figure 2 Convex or concave as shown.

[0025] Specifically, the profiling processing device 2 includes a profiling shaft 5 extending toward the mold station 3, and a processing shaft 6 extending toward the processing station 4. The profiling shaft 5 and the processing shaft 6 are coaxially arranged, and the ends of the profiling shaft 5 and the processing shaft 6 are both provided with processing wheels 7. The device is provided with two types of processing wheels 7. When it is necessary to process a convex surface on the surface of the aluminum material, a concave processing wheel 7 is used, that is, Figure 4 As shown, the processing wheel 7 is in the shape of a disk, and its rim is a concave profile 27 that is recessed inward. When a concave surface is processed on the surface of a titanium profile, a convex processing wheel 7 should be used, and at this time, the rim of the processing wheel 7 is a convex profile 26 that protrudes outward; it can be understood that the rim surface hardness of the processing wheel 7 should be greater than the processed profile, and the rim surface should be a rough surface structure, so that when the processing wheel 7 rotates, the profile surface can be ground to form the desired composite surface shape, and the processing wheel 7 can form a roughening effect on the composite surface, so that when the two metals are subsequently composited, the composite surface is more firmly bonded.

[0026] Specifically, the profiling processing device 2 includes a mounting plate 8, one side of the mounting plate 8 is hingedly connected to the processing platform 1, and the other side is provided with an angle adjustment device 9, the angle adjustment device 9 controls the angle between the mounting plate 8 and the processing platform 1; Figure 3 As shown, one side of the mounting plate 8 is hinged to the processing platform 1, so that the height positions of the processing axis 6 and the profiling axis 5 relative to the two side stations are changed through the angle adjustment device 9, so that the feeding depth of the processing wheel 7 on the profile surface can be adjusted, and a gradual deepening method can be adopted during processing, so that the profile surface can be processed more easily; it can be understood that, through the standard model placed on the side of the mold station 3, the pressing depth of the processing wheel 7 can be limited, so as to avoid the processing wheel 7 on the side of the processing station 4 from feeding too deeply and avoiding excessive processing.

[0027] The profiling shaft 5 and the processing shaft 6 are arranged on one side of the angle adjustment device 9, and a driving motor 10 is arranged on the other side. The output end of the driving motor 10 is connected to the processing shaft 6. The profiling shaft 5 and the processing shaft 6 are arranged on one side of the angle adjustment device 9 so that the height of the processing wheel 7 can be adjusted and maintained more accurately.

The end of the processing shaft 6 is provided with a driven sprocket 17, and the output end of the driving motor 10 is provided with a driving sprocket 18. The driven sprocket 17 and the driving sprocket 18 are sleeved with a chain 19.

[0028] Further, the angle adjustment device 9 includes a cross shaft 13 and an adjusting bolt 14. The mounting plate 8 is provided with a first mounting hole 28, and the processing platform 1 is provided with a second mounting hole 29.

The first mounting hole 28 is hingedly provided with a first cross shaft 13, and the second mounting hole 29 is hingedly provided with a second cross shaft 13. The adjusting bolt 14 is arranged through the sleeve portions 15 of the two cross shafts 13, and the first cross shaft 13 is rotatably connected to the adjusting bolt 14, and the second cross shaft 13 is threadedly connected to the adjusting bolt 14; Figure 4As shown, the first mounting hole 28 and the second mounting hole 29 are both in the shape of long strips, and the cross shafts 13 arranged in the two mounting holes are both hingedly arranged, so that the cross shaft 13 can rotate freely in the mounting holes, and an adjusting bolt 14 is arranged through the first cross shaft 13 and the second cross shaft 13 and the same part of the two cross shafts 13. When in use, the rotation of the mounting plate 8 can be controlled by rotating the nut on the upper part of the adjusting bolt 14, thereby controlling the height position of the processing wheel 7. It can be understood that the first cross shaft 13 and the adjusting bolt are rotatably connected to facilitate the lifting or lowering control of the mounting plate 8.

[0029] Furthermore, a mold base 20 and a mold positioning frame 21 are provided on the side of the mold station 3. The mold base 20 is fixedly arranged on the processing platform 1.

The mold positioning frame 21 corresponds to the position of the processing wheel 7 at the end of the profiling shaft 5. When in use, the standard model is fixed in the mold positioning frame 21, which can facilitate the replacement of the standard model, thereby processing metal material workpieces of different specifications and sizes.

[0030] The processing station 4 is provided with a guide rail 22, a sliding plate 23, and a workpiece positioning frame 25. The guide rail 22 is fixedly arranged on the processing platform 1, and the guide rail 22 is arranged perpendicularly to the processing axis 6.

The lower end surface of the sliding plate 23 is provided with a slider 24, and the upper end surface is provided with a workpiece positioning frame 25. The workpiece positioning frame 25 is used to position and place the workpiece to be processed. The workpiece positioning frame 25 corresponds to the position of the processing wheel 7 at the end of the processing axis 6. It can be understood that, similar to the mold work, the workpiece to be processed is fixed in the workpiece positioning frame 25, and then the sliding plate 23 can be withdrawn and slowly moved from one end of the guide rail 22 to the other end, and then returned, and the reciprocating movement is carried out in cooperation with the angle adjustment device 9 to continuously lower the height of the processing wheel 7 until the processing wheel 7 at the end of the profiling axis 5 contacts the standard model, thereby completing the processing of the workpiece.
