Description

Technical Field

[0001] This application relates to the technical field of aluminum veneer production, and in particular to a hemming device for aluminum veneer production. Background Technique

[0002] Aluminum is a light metal, and its compounds are widely distributed in nature. The aluminum resources in the earth's crust are about 40-50 billion tons, ranking third after oxygen and silicon. Among metal varieties, it ranks second only to steel, being the second largest metal. Aluminum has special chemical and physical properties. It is not only light in weight and firm in texture, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance.

[0003] Aluminum veneer is a new type of curtain wall material that uses high-quality aluminum alloy plates as the base material, and is formed through technologies such as numerical control bending, and then decorative coatings are sprayed on the surface. Aluminum alloy materials, which are materials in the traditional aviation field, are increasingly being applied to urban buildings and need to be bent during production.

[0004] The existing hemming device for aluminum veneer production with the publication number CN221414602U includes a bottom plate and an upper plate. The upper plate is supported above the bottom plate by columns at the four corners of its bottom. A support block is fixed at the middle position of the surface of the bottom plate. Side plates are vertically fixed on both side surfaces of the bottom plate. Electric push rods are horizontally installed on the outer surfaces of the side plates. The end of the extending end of the electric push rod is vertically fixed with a positioning plate. A hydraulic cylinder is installed on the surface of the upper plate, and the end of the bottom of the hydraulic cylinder is fixed with a bending abutment. In this existing technical solution, positioning plates that can be driven to move positions are arranged on both sides of the surface of the support block. When the positioning plates move to appropriate positions on both sides of the support block, aluminum plates with corresponding widths can be quickly positioned, so that the position of the aluminum plate to be bent is quickly positioned above the bending groove. Subsequently, the bending abutment is made to contact the surface of the aluminum plate and abut. After the positioning plates move outward, the bending abutment continues to lower its height to achieve the hemming work of the aluminum plate, ensuring the hemming accuracy.

[0005] In view of the above existing technology, the filter plate is placed in a fixed bending groove, and the bending abutment is made to contact the surface of the aluminum plate and abut. After the positioning plates move outward, the bending abutment continues to lower its height to achieve the hemming work of the aluminum plate. However, due to different design requirements and specific application scenarios, the bending angle of the aluminum plate during processing is not fixed. The bending groove in the above existing technology is fixedly arranged and the bending angle is fixed, and it can only be used to produce bending parts with specific angles. This means that if different bending angles are required, bending groove parts need to be replaced, which not only increases costs but also prolongs the production cycle. To solve the above problems, a hemming device for aluminum veneer production is now proposed.

[0006] The above information disclosed in this background art is only used to enhance the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

DETAILED DESCRIPTION

[0023] The following is combined with Figures 1 - 3 This application is described in further detail.

[0024] The present application embodiment discloses a folding device for aluminum veneer production. Figures 1 - 3 A folding device for aluminum single plate production includes a workbench 1, a support plate 2 supported by four pillars 3 is provided on the top of the workbench 1, an extrusion component for pressing the aluminum plate to form is provided on the support plate 2, and a folding component for bending the aluminum plate and an adjustment component for adjusting the bending angle of the aluminum plate are provided on the workbench 1;

[0025] The folding assembly includes a folding frame 1 6, a folding plate 7, a folding frame 2 8, a telescopic rod 9, and a spring 10. The folding frame 1 6 and the folding frame 2 8 are arranged on the adjustment assembly through a rotating shaft, and the folding plate 7 is slidably arranged on the folding frame 1 6. The telescopic rod 9 is located between the folding frame 1 6 and the folding plate 7, and the two ends of the telescopic rod 9 are respectively against the folding frame 1 6 and the folding plate 7, and the spring 10 is sleeved on the telescopic rod 9;

[0026] By adopting the above technical solution, the aluminum plate is placed on the workbench 1, and the position to be bent is adjusted below the extrusion assembly. The extrusion assembly is activated to press down the aluminum plate so that it abuts against the angle between the flanging plate 7 and the second flanging frame 8, completing the flanging work. When it is necessary to adjust the angle between the flanging plate 7 and the second flanging frame 8, the adjustment assembly is activated to make the two ends of the first flanging frame 6 and the second flanging frame 8 approach or move away from each other simultaneously, and the angle can be adjusted. When the angle between the first flanging frame 6 and the second flanging frame 8 changes, the flanging plate 7 will be squeezed and slide on the first flanging frame 6. However, under the guiding action of the telescopic rod 9 and the reset action of the spring 10, the flanging plate 7 always forms the required angle for flanging with the second bending frame 8.

[0027] Refer to Figure 2 As shown in the figure, the adjustment assembly includes a mounting plate 11, a guide rod 12, a bidirectional lead screw 13, a slider 14, and a motor 15. The mounting plate 11 is fixed to the bottom of the workbench 1, the guide rod 12 is fixed between the mounting plates 11, the bidirectional lead screw 13 rotates between the mounting plates 11, the slider 14 is in clearance fit with the guide rod 12, the slider 14 is in threaded fit with the bidirectional lead screw 13, and the top of the slider 14 is respectively connected to the bottoms of the first flanging frame 6 and the second flanging frame 8;

[0028] It should be noted that one section of the bidirectional lead screw 13 is a left-handed thread, and the other section is a right-handed thread. The two sliders 14 are respectively threadedly connected to the left-handed thread and the right-handed thread;

[0029] By adopting the above technical solution, the motor 15 is activated to rotate the bidirectional lead screw 13. Under the guiding action of the guide rod 12, the slider 14 drives the bottoms of the first flanging frame 6 and the second flanging frame 8 to approach or move away from each other simultaneously. Since the first flanging frame 6 and the second flanging frame 8 are cross-rotationally connected by a rotating shaft, the opening and closing directions of the tops of the first flanging frame 6 and the second flanging frame 8 are opposite to those of the bottoms, thereby adjusting the angle between the flanging plate 7 and the second flanging frame 8.

[0030] Refer to Figure 2 As shown in the figure, the extrusion assembly includes a hydraulic cylinder 4 and a flanging abutting head 5. The hydraulic cylinder 4 is fixed to the top of the support plate 2, and the telescopic end of the support plate 2 penetrates through the top of the support plate 2 and is fixed to the flanging abutting head 5;

[0031] By adopting the above technical solution, when the aluminum plate is adjusted to the required processing position, the hydraulic cylinder 4 is activated to press down the flanging abutting head 5 until the aluminum plate abuts against the angle between the flanging plate 7 and the second flanging frame 8, completing the flanging work of the aluminum plate.

[0032] Refer to Figure 1 As shown in the figure, a clamping assembly for clamping and positioning the aluminum plate is further provided on the workbench 1;

[0033] The clamping assembly includes a support block 16, an electric push rod 17, and a positioning plate 18. The support block 16 is fixed on both sides of the top of the workbench 1. The electric push rod 17 is fixed on the support block 16, and the telescopic end of the electric push rod 17 is fixed to the positioning plate 18;

[0034] It should be noted that there are two sets of the support block 16, the electric push rod 17, and the positioning plate 18, which are oppositely arranged on the workbench 1;

[0035] By adopting the above technical solution, the aluminum plate to be hemmed is placed on the positioning plate 18. Through the telescopic movement of the electric push rod 17, the positioning plate 18 can clamp and fix the aluminum plate and adjust the hemming position of the aluminum plate at the same time, which is beneficial to improving the hemming accuracy.

[0036] Refer to Figure 1 , the hemming head 5 is always located directly above the angle between the first hemming frame 6 and the second hemming frame 8;

[0037] By adopting the above technical solution, the accuracy of hemming the aluminum plate by the hemming head 5 can be guaranteed, and the processing efficiency can be improved.

[0038] Refer to Figure 2 , there are openings on the workbench 1 for the first hemming frame 6 and the second hemming frame 8 to rotate and adjust. The diameter of the opening expands outward from top to bottom;

[0039] By adopting the above technical solution, the setting of the opening provides space for the rotation and adjustment of the first hemming frame 6 and the second hemming frame 8.

[0040] The implementation principle of the hemming device for aluminum single plates in the embodiment of this application is as follows: Before use, first start the motor 15 to make the bidirectional lead screw 13 rotate. Under the guiding action of the guide rod 12, the slider 14 drives the bottoms of the first hemming frame 6 and the second hemming frame 8 to approach or move away from each other at the same time, and adjust the included angle between the first hemming frame 6 and the second hemming frame 8 to the angle required for hemming. During use, place the aluminum plate on the positioning plate 18, start the electric push rod 17 to clamp and position the aluminum plate by the positioning plate 18, and adjust the position of the aluminum plate to be hemmed directly below the hemming head 5. Start the hydraulic cylinder 4 to press the hemming head 5 down until it abuts against the included angle between the aluminum plate, the hemming plate 7, and the second hemming frame 8, and complete the hemming work of the aluminum plate. When the hemming processing angle changes, repeat the angle adjustment steps before use, which effectively reduces the downtime of the equipment and improves the production efficiency.
