Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to an aluminum profile drilling machine. Background Technology

[0002] Aluminum profiles are products made of aluminum and other alloying elements. They are typically first processed into castings, forgings, foils, plates, strips, tubes, rods, and profiles, and then manufactured through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metallic element is aluminum, with the addition of various alloying elements to improve the properties of the aluminum material.

[0003] During the processing of aluminum profiles, a drilling machine is required to drill holes in the aluminum profiles. A drilling machine usually includes a punching head and a punching table. The punching head quickly descends to punch holes in the aluminum profile on top of the punching table. However, in existing drilling machines, the punching head is prone to collision with the aluminum profile due to excessive force during the rapid descent. Reducing the punching speed of the punching head will affect the punching effect, resulting in poor practicality.

[0004] Chinese utility model patent (authorization announcement number: CN206356434U, title: A stamping-type drilling machine to prevent displacement) includes a stamping base, a bracket, a stamping cylinder, an elastic clamping device, a mounting plate, an elastic clamping device, an elastic telescopic sleeve, a clamping component, a stamping rod, and a drill rod. The beneficial effects of this utility model are: at the moment the stamping rod contacts the workpiece, it clamps the workpiece from around it, preventing displacement when the workpiece contacts the stamping rod. The lowest point of the elastic clamping device in its relaxed state is lower than the lowest point of the drill rod, thus fixing the workpiece before stamping. As the stamping rod descends, the fixing effect of the elastic clamping device on the workpiece becomes stronger, improving the processing accuracy of this utility model. However, its elastic clamping device is only suitable for drilling holes in panel-type aluminum profiles and is inconvenient for drilling holes in curved plates. Utility Model Content

[0025] like Figure 1 and 2 As shown, an aluminum profile drilling machine includes a workbench 1 mounted on the ground, a gantry frame 2 fixed on the workbench 1, a hydraulic cylinder 3 fixed on the gantry frame 2, an upper die base 4 fixed on the piston rod of the hydraulic cylinder 3, a guide rod 5 penetrating the gantry frame 2 fixed on the top surface of the upper die base 4, a punch head detachably mounted on the bottom surface of the upper die base 4, and a lower die base 6 detachably mounted on the workbench 1 below the upper die base 4. The lower die base 6 has a blanking hole corresponding to the punch head, penetrating the workbench 1. Two support bases 7 are also mounted on the workbench 1, located on opposite sides of the lower die base 6. The line connecting the support bases 7 is perpendicular to the plane where the gantry 2 is located. A pair of rollers 8 are installed on the support bases 7. The axis of the rollers 8 is parallel to the plane where the gantry 2 is located. The rollers 8 are used to clamp the curved aluminum profile. The curved plate passes through the rollers 8 on one support base 7 and then through the rollers 8 on the other support base 7, thereby fixing the curved plate on the lower die base 6 for punching and drilling (the lower die base provides an upward pushing force, and the rollers provide a downward pressing force, so that the curved plate is slightly deformed and thus fixed). The structure is simple and easy to use, avoiding manual fixing of the curved plate, reducing the labor intensity of workers and improving work efficiency.

[0026] In this embodiment, as Figure 1-3As shown, a T-shaped slide groove 9 is provided on the workbench 1. The extension direction of the T-shaped slide groove 9 is perpendicular to the plane where the gantry frame 2 is located. A nut 10 is slidably installed in the T-shaped slide groove 9. The support seat 7 is tightened onto the A nut 10 by bolts 11. By adjusting the distance between the two support seats 7, arc plates of the same thickness but different arc lengths can be clamped, which increases the application range of this utility model.

[0027] In this embodiment, as Figure 1 and 2 As shown, the support base 7 is U-shaped, and oblong through holes 12 are provided on both sides of the support base 7 in the vertical direction. A B nut 13 is screwed on the rotating shaft of the roller 8. The B nut 13 is used to fix the rotating shaft of the roller 8 in the oblong through hole 12. By adjusting the distance between the two rollers 8, arc plates with the same arc length but different thicknesses can be clamped.

[0028] In this embodiment, as Figure 1 , 2 As shown in Figure 4, a drawer 14 is slidably installed on the bottom of the workbench 1. The drawer 14 is located below the material drop hole. A pair of through holes are opened on the front panel of the drawer 14. A U-shaped handle 15 is installed on the front panel. The two ends of the U-shaped handle 15 pass through the corresponding through holes. A limiting member 16 is provided at the end of the U-shaped handle 15. The limiting member 16 is stuck on the inner wall of the drawer 14. When the U-shaped handle 15 is not in use, it is pushed into the drawer 14 to prevent personnel's clothing from being caught and causing safety hazards.

[0029] In this embodiment, as Figure 4 As shown, the limiting component 16 is a nut, and the end of the U-shaped handle 15 is threaded. The limiting component 16 is screwed onto the end of the U-shaped handle 15 to prevent the U-shaped handle 15 from coming off, while facilitating disassembly and replacement.

[0030] In this embodiment, as Figure 4 As shown, a spring 17 is also fitted on the U-shaped handle 15. The two ends of the spring 17 abut against the limiting member 16 and the front panel respectively. Through the restoring force of the spring 17, after the external force on the U-shaped handle 15 is released, the U-shaped handle 15 automatically retracts and locks itself on the front panel, preventing the U-shaped handle 15 from slipping due to vibration.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
