Description

Technical Field

[0001] This invention belongs to the field of aluminum profile processing technology, and more specifically, it is a multi-angle bending device for aluminum profile processing. Background Technology

[0002] A bending machine is a simple bending machine that can be operated manually or by a motor. The simplest method is to securely fix the steel plate to the machine's worktable using a template with a bending radius. The protruding portion of the material is placed on another worktable that can rotate around the center of the bending radius.

[0003] Patent document CN112775673A discloses a fully automatic aluminum bending machine, including a frame. The frame is arranged in sequence with a feeding mechanism, a pressing mechanism, and a clamping mechanism according to the flow direction of the aluminum material. A cutting mechanism and a first suction mechanism are arranged on the frame between the pressing mechanism and the clamping mechanism. A bending mechanism is arranged on the side of the frame away from the cutting mechanism from the clamping mechanism. A placement seat is arranged on the side of the frame away from the clamping mechanism from the bending mechanism. A second suction mechanism is arranged on the frame between the placement seat and the bending mechanism. The machine also includes a control mechanism for controlling the fully automatic aluminum bending machine, capable of automatically cutting coiled aluminum material to a fixed length, automatically bending the aluminum material, and neatly arranging the cut aluminum material.

[0004] The aforementioned fully automatic aluminum bending machine has certain shortcomings in use. Traditional bending machines lack a bending plate correction structure, and the processing of aluminum profiles is a one-time forming operation. When the bending angle of the aluminum profile is large, it is impossible to perform a bending repair operation by reverse bending. Its functionality is limited, reducing the effectiveness of the bending device. Secondly, the aforementioned fully automatic aluminum bending machine can only be used for processing sheet-shaped aluminum profiles and cannot be used for bending tubular aluminum profiles. This prevents it from being arbitrarily adjusted according to the structure of the aluminum profile, reducing the applicability of the fully automatic aluminum bending machine. Furthermore, the aforementioned fully automatic aluminum bending machine lacks an auxiliary correction structure, and the aluminum profile is prone to tilting during movement. Directly bending tilted aluminum profiles can easily result in slanted edges, reducing the processing accuracy of the bending device. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-angle bending device for aluminum profile processing, which can solve the existing problems.

[0006] The problem solved by this invention is:

[0007] 1. Traditional bending machines do not have a bending plate straightening structure. The bending machine processes aluminum profiles in one step. When the bending plate angle of the aluminum profile is large, it is impossible to perform bending repair operation on the aluminum profile by reverse bending. The functionality is limited, which reduces the effectiveness of the bending device.

[0008] 2. The above-mentioned fully automatic aluminum bending machine can only be used for processing sheet aluminum profiles and cannot be used for bending tubular aluminum profiles. This makes it impossible to adjust it arbitrarily according to the structure of the aluminum profile, thus reducing the applicability of the fully automatic aluminum bending machine.

[0009] 3. The above-mentioned fully automatic aluminum bending machine does not have an auxiliary correction structure. The aluminum profile is prone to tilting when moving. If the tilted aluminum profile is directly bent, it is easy to produce a slanted edge, which reduces the processing accuracy of the bending device.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A multi-angle bending device for processing aluminum profiles includes a fixed frame, a fixed base, and a bending plate. The fixed frame is disposed on the upper part of the fixed base, and the bending plate is disposed on the upper part of the fixed base near the fixed frame. A fixing clip is spliced ​​and installed on the outer surface of one side of the bending plate. Two sets of positioning push rods for adjusting the position of the aluminum profile are disposed on the upper part of the fixed base near the fixed frame. A lifting frame for conveying the aluminum profile is movably installed at the upper part of one end of the fixed frame, and a lifting platform for bending tubular aluminum materials is movably installed at the upper part of the other end of the fixed frame. Several sets of first push rods and second push rods are movably installed on the inner side of the lifting platform.

[0012] As a further technical solution of the present invention, a mating sleeve is movably sleeved on the outer surface of the positioning push rod, a limiting chuck is movably installed at one end of the positioning push rod, and a fastening bolt for locking the positioning push rod is provided on the upper part of the mating sleeve. By using the two sets of positioning push rods, the user can adjust the position of both sides of the plate aluminum profile when it moves, so as to prevent the plate aluminum profile from tilting and make it move in coordination with the limiting chuck at one end of the positioning push rod.

[0013] As a further technical solution of the present invention, several sets of first and second push rods are symmetrically arranged. Rollers are movably installed at one end of each of the first and second push rods. By using the arrangement of the first and second push rods, the tubular aluminum profile can be bent. When the tubular aluminum profile passes between the first and second push rods, a certain number of first and second push rods are used to fix the tubular aluminum profile. The set of first and second push rods at its tail moves, thereby bending one end of the tubular aluminum profile. The user can control the use of the first and second push rods through the lifting platform as needed.

[0014] As a further technical solution of the present invention, hydraulic rods are provided at the four corners of the lower end of the lifting platform, and a groove is provided at the upper end of the lifting platform. Several sets of rollers are arranged side by side in the middle of the groove. The lifting platform and the fixed base are movably connected by hydraulic rods. The hydraulic rods can drive the lifting platform to move up and down. When performing edge bending operation on plate-shaped aluminum profiles, the lifting platform can be moved down to retract the first and second top rods. When performing bending operation on tubular aluminum profiles, the lifting platform can be moved up to release the first and second top rods.

[0015] As a further technical solution of the present invention, the folding plate and the fixing cover are spliced ​​and fixed by a slot. A lifting frame is movably installed on the inner side of the fixing cover. With the setting of the fixing cover, when the folding angle of the plate aluminum profile is too large, the folding plate rotating in the opposite direction can be used to perform the folding correction operation. In use, the fixing cover is assembled on the folding plate so that the fixing cover fixes the other side of the plate aluminum profile. When the folding plate is flipped, the plate aluminum profile bends downward, thereby adjusting its folding angle.

[0016] As a further technical solution of the present invention, the fixed cover and the lifting frame are driven by an adjustment disc. Two sets of positioning rollers are movably installed on the inner side of the lifting frame. The two sets of positioning rollers are arranged side by side. The lower end of the adjustment disc is provided with a threaded rod. The user can adjust the height of the lifting frame by rotating the adjustment disc to drive the threaded rod, so that the two sets of positioning rollers of the lifting frame are in close contact with the surface of the plate-shaped aluminum profile, thereby adapting to aluminum profiles of different thicknesses.

[0017] As a further technical solution of the present invention, a docking base plate is movably installed at one end of the folded edge plate, and a hydraulic push rod is provided on the other side of the folded edge plate. The folded edge plate is driven by the hydraulic push rod to adjust the folded edge plate at a certain angle. The docking base plate plays an auxiliary role in fixing the installation of the folded edge plate. The folded edge plate and the docking base plate are movably connected by a hinge.

[0018] As a further technical solution of the present invention, a movable slider is movably installed at one end of the hydraulic jack, and a fixed base plate is movably installed at the other end of the hydraulic jack. The outer surface of the folded edge plate is provided with a slide rail for use with the movable slider. When the hydraulic jack is extended or retracted, the hydraulic jack drives the movable slider, so that the movable slider moves on the slide rail, thereby adjusting the contact point between the hydraulic jack and the folded edge plate.

[0019] As a further technical solution of the present invention, a conveying roller is movably installed on the inner side of the lifting frame. The conveying roller has an arc-shaped groove in the middle. Both ends of the lifting frame are provided with positioning push rods. The positioning push rods and the lifting frame are driven by a lifting rod. One end of the lifting frame is provided with a motor for driving the conveying roller to rotate. The motor drives the conveying roller to rotate using a gear structure. When the aluminum profile passes through the lower part of the conveying roller, it drives it to move. At the same time, the arc-shaped groove makes it more suitable for tubular aluminum materials.

[0020] As a further technical solution of the present invention, a clamping block is movably installed on the upper part of the fixed base, and the fixed base and the clamping block are connected by a fixing frame. Several sets of lower rollers are movably installed on the inner side of the upper end of the fixed base. By using the setting of the lower rollers, the friction between the aluminum profile and the fixed base can be reduced when the profile moves.

[0021] The beneficial effects of this invention are:

[0022] 1. By setting up a folding plate and a fixing cover, this multi-angle folding device for aluminum profile processing allows for the folding and repair of sheet aluminum profiles with excessively large folds when using the folding plate and fixing cover. The fixing cover, once installed, secures the other side of the sheet aluminum profile. Combined with the reverse folding plate, it allows for folding and repair of the sheet aluminum profile in the opposite direction. In use, the sheet aluminum profile is placed on top of the fixed base. The lower roller reduces friction between the aluminum profile and the fixed base during movement. The user can adjust the height of the conveying roller by activating the lifting rod, which drives the lifting frame up and down, according to the thickness of the sheet aluminum profile. The motor drives the conveying roller to rotate via a gear structure, moving the aluminum profile as it passes under the conveying roller. The arc-shaped groove design allows for better application to tubular materials. When one end of a sheet aluminum profile moves to the folding plate, the clamping blocks of the fixing frame first fix its folding position. The folding plate is then driven by a hydraulic jack, allowing it to adjust its angle. The docking base plate assists in fixing the folding plate. The folding plate and the docking base plate are connected by a hinge. The rotation of the folding plate completes the folding operation of the sheet aluminum profile. Next, when the hydraulic jack extends or retracts, it drives a sliding block, which moves along a slide rail, adjusting the contact point between the hydraulic jack and the folding plate. A slotted structure is used to attach a fixing cover to the folding plate. The hydraulic jack drives the folding plate to rotate, causing it to bend the sheet aluminum profile to the other side in conjunction with the fixing cover, thus adjusting the folding angle. This multi-angle folding device for aluminum profile processing has a folding correction structure, improving its performance.

[0023] 2. By setting up a first top rod, a second top rod, and a lifting platform, this multi-angle bending device for aluminum profile processing can be used to bend tubular aluminum profiles. During operation, the bending plate is laid flat. When the tubular aluminum profile passes between the first and second top rods, a certain number of first and second top rods are used to fix the tubular aluminum profile. By moving a set of first and second top rods at its tail, one end of the tubular aluminum profile is bent. The user can control the use of the first and second top rods through the lifting platform as needed. The lifting platform can be driven up and down using hydraulic rods. When bending sheet-like aluminum profiles, the lifting platform can be lowered to retract the first and second top rods. When bending tubular aluminum profiles, the lifting platform can be raised to extend the first and second top rods. This allows it to perform bending operations on both sheet-like and tubular aluminum profiles without affecting the bending operation, thus improving its functionality and applicability.

[0024] 3. By setting positioning push rods, the multi-angle bending device for aluminum profile processing has a correction structure for aluminum profile movement, preventing tilting during movement. During operation, the user can use two sets of positioning push rods to adjust the position of the sheet aluminum profile on both sides as it moves, preventing tilting. The positioning push rods are coordinated with the limiting rollers at one end. When the sheet aluminum profile passes between the two sets of positioning push rods, the correction operation is completed, preventing tilting and thus preventing slanted edges during bending. The length of the positioning push rods can be adjusted according to the material width, ensuring they fit snugly against both sides of the material. The fastening bolts are rotated to lock the positioning push rods in place, improving the overall performance. Attached Figure Description

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] like Figure 1-7 As shown, a multi-angle bending device for processing aluminum profiles includes a fixed frame 2, a fixed base 3, and a bending plate 6. The fixed frame 2 is located on the upper part of the fixed base 3, and the bending plate 6 is located on the upper part of the fixed base 3 near the fixed frame 2. A fixing cover 13 is spliced ​​and installed on the outer surface of one side of the bending plate 6. Two sets of positioning push rods 27 for adjusting the position of the aluminum profile are provided on the upper part of the fixed base 3 near the fixed frame 2. A lifting frame 1 for conveying aluminum profiles is movably installed at the upper part of one end of the fixed frame 2, and a lifting platform 5 for bending tubular aluminum materials is movably installed at the upper part of the other end of the fixed frame 2. Several sets of first push rods 24 and second push rods 25 are movably installed on the inner side of the lifting platform 5.

[0036] The outer surface of the positioning push rod 27 is movably fitted with a mating sleeve 28. One end of the positioning push rod 27 is movably mounted with a limiting chuck 30. The upper part of the mating sleeve 28 is provided with a fastening bolt 29 for locking the positioning push rod 27. By using the two sets of positioning push rods 27, the user can adjust the position of the two sides of the plate aluminum profile when it moves, so as to prevent the plate aluminum profile from tilting and make it move in coordination with the limiting chuck 30 at one end of the positioning push rod 27.

[0037] Several sets of first push rods 24 and second push rods 25 are symmetrically arranged. Rollers 26 are movably installed at one end of each first push rod 24 and second push rod 25. The arrangement of the first push rods 24 and second push rods 25 allows for bending operations on tubular aluminum profiles. When the tubular aluminum profile passes between the first push rods 24 and second push rods 25, a certain number of first push rods 24 and second push rods 25 are used to fix the tubular aluminum profile. The set of first push rods 24 and second push rods 25 at the tail end moves, thereby bending one end of the tubular aluminum profile. The user can control the use of the first push rods 24 and second push rods 25 through the lifting platform 5 as needed.

[0038] Hydraulic rods 4 are provided at the four corners of the lower end of the lifting platform 5. The upper end of the lifting platform 5 is provided with a groove 22, and several sets of rollers 23 are arranged side by side in the middle of the groove 22. The lifting platform 5 and the fixed base 3 are movably connected by hydraulic rods 4. The lifting platform 5 can be driven to move up and down by using hydraulic rods 4. When performing edge bending operation on plate-shaped aluminum profiles, the lifting platform 5 can be moved down to retract the first top rod 24 and the second top rod 25. When performing bending operation on tubular aluminum profiles, the lifting platform 5 can be moved up to release the first top rod 24 and the second top rod 25.

[0039] The folding plate 6 and the fixing cover 13 are spliced ​​and fixed together by a slot. The inner side of the fixing cover 13 is movably installed with a lifting frame 20. With the setting of the fixing cover 13, when the folding angle of the plate aluminum profile is too large, the folding plate 6 rotates in the opposite direction to perform the folding correction operation. In use, the fixing cover 13 is assembled on the folding plate 6 so that the fixing cover 13 fixes the other side of the plate aluminum profile. When the folding plate 6 is flipped, the plate aluminum profile bends downward, thereby adjusting its folding angle.

[0040] The fixed cover 13 and the lifting frame 20 are driven by the adjusting plate 19. Two sets of positioning rollers 21 are movably installed on the inner side of the lifting frame 20. The two sets of positioning rollers 21 are arranged side by side. The lower end of the adjusting plate 19 is provided with a threaded rod. By rotating the adjusting plate 19 to drive the threaded rod, the user can adjust the working height of the lifting frame 20 so that the two sets of positioning rollers 21 of the lifting frame 20 are in close contact with the surface of the plate-shaped aluminum profile, thereby adapting to aluminum profiles of different thicknesses.

[0041] One end of the folded edge plate 6 is movably mounted with a docking base plate 14, and the other side of the folded edge plate 6 is provided with a hydraulic push rod 16. The folded edge plate 6 is driven by the hydraulic push rod 16 to make a certain angle adjustment. The docking base plate 14 plays an auxiliary role in fixing the installation of the folded edge plate 6. The folded edge plate 6 and the docking base plate 14 are movably connected by a hinge.

[0042] One end of the hydraulic jack 16 is movably mounted with a movable slider 17, and the other end of the hydraulic jack 16 is movably mounted with a fixed base plate 15. The outer surface of the folded edge plate 6 is provided with a slide rail 18 that works in conjunction with the movable slider 17. When the hydraulic jack 16 is extended or retracted, the hydraulic jack 16 drives the movable slider 17, causing the movable slider 17 to move on the slide rail 18, thereby adjusting the contact point between the hydraulic jack 16 and the folded edge plate 6.

[0043] A material conveying roller 10 is movably installed on the inner side of the lifting frame 1. The material conveying roller 10 has an arc-shaped groove 11 in the middle. Both ends of the lifting frame 1 are provided with positioning push rods 27. The positioning push rods 27 and the lifting frame 1 are driven by the lifting rod 12. One end of the lifting frame 1 is provided with a motor 9 for driving the material conveying roller 10 to rotate. The motor 9 drives the material conveying roller 10 to rotate using a gear structure. When the aluminum profile passes through the lower part of the material conveying roller 10, it drives it to move. At the same time, the arc-shaped groove 11 makes it easier to use tubular aluminum materials.

[0044] A clamping block 7 is movably installed on the upper part of the fixed base 3. The fixed base 3 and the clamping block 7 are connected by a fixing frame 2. Several sets of lower rollers 8 are movably installed on the inner side of the upper end of the fixed base 3. By using the setting of the lower rollers 8, the friction between the aluminum profile and the fixed base 3 can be reduced when it moves.

[0045] This multi-angle bending device for aluminum profile processing, by setting a bending plate 6 and a fixing cover 13, allows for bending and repairing of sheet aluminum profiles with excessively large bending edges by assembling the fixing cover 13 on the bending plate 6. After installation, the fixing cover 13 can fix the other side of the sheet aluminum profile. With the reversed bending plate 6, the bending and repair operation of the sheet aluminum profile can be performed in the opposite direction. In use, the sheet aluminum profile is placed on the fixing base 3. At the upper end, the lower roller 8 reduces the friction between the aluminum profile and the fixed base 3 during movement. The user can adjust the height of the conveying roller 10 by activating the lifting rod 12, which drives the lifting frame 1 to move up and down, based on the thickness of the sheet aluminum profile. The motor 9 drives the conveying roller 10 to rotate via a gear structure, moving the aluminum profile as it passes under the conveying roller 10. Simultaneously, the arc-shaped groove 11 allows for better... Applicable to tubular aluminum materials, when one end of the sheet aluminum profile moves to the folding plate 6, the clamping block 7 of the fixing frame 2 is first used to fix its folding position. The folding plate 6 is then driven by the hydraulic push rod 16, allowing it to adjust at a certain angle. The docking base plate 14 assists in fixing the folding plate 6. The folding plate 6 and the docking base plate 14 are connected by a hinge. The rotation of the folding plate 6 completes the folding operation of the sheet aluminum profile. Secondly, when the hydraulic push rod 16 is extended or retracted, the hydraulic... The pressure rod 16 drives the movable slider 17, causing the movable slider 17 to move on the slide rail 18, thereby adjusting the contact point between the hydraulic pressure rod 16 and the folding plate 6. The fixing cover 13 is installed on the folding plate 6 using the slot structure. The hydraulic pressure rod 16 drives the folding plate 6 to flip, so that the folding plate 6, together with the fixing cover 13, drives the plate aluminum profile to bend to the other side, thereby adjusting the folding angle of the plate aluminum profile. This gives the multi-angle folding device for aluminum profile processing a folding correction structure, improving its performance.

[0046] By setting up a first top rod 24, a second top rod 25, and a lifting platform 5, this multi-angle bending device for aluminum profile processing can be used to bend tubular aluminum profiles. During operation, the bending plate 6 is laid flat. When the tubular aluminum profile passes between the first top rod 24 and the second top rod 25, a certain number of the first top rods 24 and the second top rods 25 are used to fix the tubular aluminum profile. By moving a set of first top rods 24 and the second top rods 25 at its tail, one end of the tubular aluminum profile is bent. The user can adjust the bending angle according to the situation. The lifting platform 5 controls the use of the first top rod 24 and the second top rod 25. The hydraulic rod 4 can drive the lifting platform 5 to move up and down. When performing edge bending operations on sheet aluminum profiles, the lifting platform 5 can be moved down to retract the first top rod 24 and the second top rod 25. When performing bending operations on tubular aluminum profiles, the lifting platform 5 can be moved up to release the first top rod 24 and the second top rod 25. While not affecting the edge bending processing operation of sheet aluminum profiles, it also enables them to have the bending function of tubular aluminum profiles, thus improving their functionality and applicability.

[0047] By setting positioning push rods 27, the multi-angle bending device for aluminum profile processing has a correction structure for aluminum profile movement, preventing the aluminum profile from tilting during movement. During operation, the user can use the two sets of positioning push rods 27 to adjust the position of the plate aluminum profile on both sides as it moves, preventing the plate aluminum profile from tilting. This allows the positioning push rods 27 to move in conjunction with the limiting rollers 30 at one end. When the plate aluminum profile passes between the two sets of positioning push rods 27, the correction operation of the plate aluminum profile is completed, preventing the plate aluminum profile from tilting. This prevents the plate aluminum profile from having a slanted edge during bending. At the same time, the length of the positioning push rods 27 can be adjusted according to the material width, so that the positioning push rods 27 are close to both sides of the material. The fastening bolts 29 are rotated to lock and fix the positioning push rods 27, improving its performance.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
