Description

Technical Field

[0001] This utility model relates to the technical field of aluminum single-panel processing equipment, and in particular to an aluminum single-panel processing device with adjustable bending degree. Background Technology

[0002] Aluminum single-panel bending is a process in which a CNC bending machine applies pressure to a pre-cut aluminum sheet, causing it to plastically deform along a set angle. Precise calculation of the bending coefficient and control of the radius of curvature (R-angle) are required to prevent surface coating cracking. High-precision molds and positioning systems are employed, and this process is widely used in architectural curtain wall design.

[0003] Traditional equipment relies on fixed molds or manual adjustment of the support angle, which cannot achieve precise and rapid setting of the bending angle. Moreover, mold replacement is cumbersome and difficult to adapt to different bending radii and irregular shape processing requirements, resulting in limited processing range. Conventional structures lack dynamic compensation mechanisms, and the springback of aluminum sheets during stamping cannot be effectively offset, which can easily cause deviations in the angle of the finished product. At the same time, rigid support surfaces are prone to stress concentration in the sheet material when bending, increasing the risk of cracking or plastic deformation. To address these issues, an aluminum single-panel processing device with adjustable bending degree is provided. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum single-panel processing device with adjustable bending degree, comprising:

[0006] Main frame of the control panel;

[0007] An aluminum plate ballast mechanism is provided above the main frame of the operating table. The aluminum plate ballast mechanism is used to drive the extrusion plate to move up and down.

The embodiments of this utility model will be described below based on its overall structure.

[0026] Reference Figures 1 to 4 In this embodiment of the invention, an aluminum single-panel processing device with adjustable bending degree includes:

[0027] Main frame of the control panel 1;

[0028] Aluminum plate ballast mechanism 2 is installed above the main frame 1 of the operating table. Aluminum plate ballast mechanism 2 is used to drive the extrusion plate to move up and down.

[0029] The aluminum plate mounting mechanism 3 is set above the main frame 1 of the operating table. The aluminum plate mounting mechanism 3 is used to place the aluminum single plate to be processed and to provide it with external support during the extrusion process.

[0030] The aluminum plate ballast mechanism 2 includes two sets of fixed brackets 21. The two sets of fixed brackets 21 are fixedly connected to both ends of the bracket above the main frame 1 of the operating table. Each set of fixed brackets 21 has a set of first electric telescopic rods 22 embedded in its inner side. The movable ends of the two sets of first electric telescopic rods 22 are fixedly connected to fixed long plates 23. The inner side of the fixed long plates 23 has through holes, which can be used with screws to connect and fix extrusion plates of different sizes.

[0031] The above scheme is adopted: the first electric telescopic rod 22 controls the vertical movement of the fixed long plate 23 through synchronous telescopic control, the through hole spacing is set to meet the installation requirements of screws of different lengths, and by replacing the extrusion plate with different curvatures or angles, a variable stamping die is formed in conjunction with the screw fastening. The double-sided symmetrical layout of the fixed bracket 21 ensures that the downward pressure is evenly distributed, and avoids the aluminum single plate from deflecting during the bending process.

[0032] The aluminum plate mounting mechanism 3 includes a rubber pad 31, with side fixing bases 32 symmetrically arranged on both sides of the rubber pad 31. The bottoms of the rubber pad 31 and the two sets of side fixing bases 32 are fixedly connected to the bottom plate of the main frame 1 of the operating table. A rotating inner abutment plate 33 is rotatably connected above the side fixing bases 32. Two sets of second electric telescopic rods 34 are fixedly connected above each set of side fixing bases 32. A slotted sliding seat 35 is fixedly connected to the movable end of the second electric telescopic rod 34. One end of a support spring 36 is fixedly connected to the inner wall of the slotted sliding seat 35, and the other end of the support spring 36 is fixed. A supporting plate 37 is connected to the slotted sliding seat 35. A connecting arm 38 is provided on the inner side of the slotted sliding seat 35. One end of the connecting arm 38 is rotatably connected to a lower rotating seat 39. The lower rotating seat 39 is fixedly connected below the rotating inner plate 33. The slotted sliding seat 35 has symmetrically opened grooves that extend to its outer side. The two sides of the supporting plate 37 and the two sides of the connecting arm 38 away from the lower rotating seat 39 are fixedly connected to sliding columns that are adapted to the grooves. When the supporting spring 36 is not subjected to external force, it is in a slightly compressed state. At this time, the sliding columns on both sides of the connecting arm 38 are close to the outermost edge of the inner groove of the slotted sliding seat 35.

[0033] Using the above scheme: When the second electric telescopic rod 34 pushes the slotted sliding seat 35 to move vertically, it drives the rotating inner abutment plate 33 to rotate around the axis through the connecting rotating arm 38. When the pressure plate presses down on the aluminum single plate, the rebound force generated by the deformation of the aluminum plate pushes the rotating inner abutment plate 33 to expand slightly outward. At this time, the support abutment plate 37 slides along the slide groove and compresses the support spring 36, forming a dynamic bending compensation mechanism. The pre-compression of the support spring 36 ensures that the rotating inner abutment plate 33 maintains the set angle in the initial state. During the stamping process, the rebound of the aluminum plate is absorbed by the elastic deformation. The cooperation between the slide groove and the slide column limits the maximum compensation stroke. The rubber pad 31 provides buffer for the bottom of the bent aluminum plate while avoiding scratches on the surface of the aluminum plate.

[0034] The working principle of this utility model is as follows: The aluminum single plate to be processed is placed horizontally on the aluminum plate mounting mechanism 3, and the two sides of the aluminum plate are in contact with the inner side of the rotating inner abutment plate 33. At this time, the second electric telescopic rod 34 is in the initial contraction state, and the pre-compression force of the support spring 36 makes the sliding column of the connecting rotating arm 38 closely adhere to the outer side of the slotted sliding seat 35, and the rotating inner abutment plate 33 maintains the set initial support angle.

[0035] Based on the target bending angle, two sets of second electric telescopic rods 34 are simultaneously activated to push the slotted sliding seat 35 to move horizontally. The slotted sliding seat 35 drives the connecting rotating arm 38 to rotate around the lower rotating seat 39, thereby driving the rotating inner abutment plate 33 to rotate around the axis of the side fixed base 32, adjusting the tilt angle of the rotating inner abutment plates 33 on both sides to form a V-shaped or U-shaped support cavity that matches the target bending arc.

[0036] Select the appropriate extrusion plate according to the bending requirements. The plate is fixed by passing the screw through the through hole of the fixed long plate 23. The two sets of first electric telescopic rods 22 are activated to push the fixed long plate 23 down simultaneously, which drives the extrusion plate to press the aluminum single plate vertically down. Under the pressure of the plate, the aluminum single plate gradually indents into the rubber pad 31 and is bent and deformed by the constraint of the inclined surface of the rotating inner abutment plate 33 on both sides.

[0037] When the pressure plate is pressed down to the limit position, the aluminum single plate generates an outward pushing force on the rotating inner abutment plate 33 due to the material rebound, which forces the support abutment plate 37 to slide inward along the slide groove and further compress the support spring 36, causing the rotating inner abutment plate 33 to expand slightly outward. This process offsets the rebound of the aluminum plate. The limiting structure of the slide groove and the slide column prevents overcompensation. The elastic deformation of the support spring 36 is automatically matched according to the strength of the aluminum plate and the pressure of the pressure plate to ensure accurate forming of the bending angle.

[0038] After stamping is completed, the first electric telescopic rod 22 lifts and fixes the long plate 23. The aluminum single plate maintains its bent shape due to plastic deformation. The second electric telescopic rod 34 moves in the opposite direction to drive the rotating inner abutment plate 33 to return to the initial angle. The support spring 36 returns to the pre-compressed state, and the operator can safely take out the finished product. The elastic properties of the rubber pad 31 reduce the indentation at the bottom of the aluminum plate bending point during the pressing process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
