Description

Technical Field

[0001] The present invention relates to the field of bending forming, and more specifically, to a bending machine for aluminum alloy materials. Background Art

[0002] Aluminum alloy has advantages such as corrosion resistance and relatively light weight, and is widely used in industries such as the construction industry, machinery manufacturing industry, ships and automobiles. When bending and processing aluminum alloy plates and pipes, a press brake is generally used to stamp and bend thin aluminum alloy materials into shape.

[0003] Traditional equipment relies on pre-designed fixed molds. For plates or pipes of different specifications, the molds need to be frequently replaced, resulting in production interruptions and low efficiency. Especially in the scenario of multi-variety and small-batch customized production, the cost of mold replacement is high, and it is difficult to meet the requirements of flexible manufacturing. When manually adjusting the mold, operation errors are likely to occur. When different specifications of aluminum alloy plates or pipes need to be processed, operators need to spend a lot of time replacing and adjusting the mold, which greatly reduces production efficiency. It is highly dependent on manual operation, and operators are prone to human errors during the mold adjustment process, resulting in reduced forming accuracy and material waste. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a bending machine for aluminum alloy materials.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

At the top of the support frames, there are fixedly connected hydraulic rods. The output ends of the hydraulic rods are fixedly connected with a moving mold. In the middle of the upper surface of the base, there is fixedly connected a fixed mold. On both sides of the fixed mold, there are adaptive components for adapting to aluminum alloy materials of different widths.

[0007] The adaptive component includes a first chute opened at the top of the fixed mold and a rotating shaft rotatably connected to one side of the fixed mold. Inside the first chute, there is a slidably connected first limiting strip. On one side of the rotating shaft, there is fixedly connected a first gear. On one side of the first limiting strip, there is fixedly connected a connecting rod. At the bottom of the connecting rod, there is fixedly connected a first rack. On one side of the connecting rod, there is fixedly connected a first spring.

[0008] Further, there are four first limiting strips. The first limiting strips are grouped in pairs on the same side. Inside two of the first limiting strips, there is a slidably connected first limiting strip. The first spring is located between two connecting rods. On one side of the first limiting strip, there is an inclined surface. The tooth surfaces of the two first racks are arranged opposite to each other, one above the other. The first gear is located between the two first racks and meshes with each other.

[0009] Further, a synchronization component for adapting to the width of the aluminum alloy material is provided on the lower surface of the moving mold. The synchronization component includes two second limiting strips sliding on the lower surface of the moving mold, a hollow rod fixed to the top of the connecting rod, and two slots opened on both sides of the upper surface of the moving mold. One side of the second limiting strip is fixedly connected with a fixed block.

[0010] Further, one side of the fixed block extends into the interior of the hollow rod. The hollow rod and the fixed block are slidably adapted to each other. The top of the hollow rod penetrates into the interior of the slot. The second limiting strip and the first limiting strip are adapted to each other.

[0011] Further, a positioning component for positioning the two first limiting strips is provided inside the fixed mold. The positioning component includes trigger components provided on both sides of the top of the fixed mold, second slots opened on both sides inside the fixed mold, and a second gear fixed to the outer surface of the rotating shaft. A third spring is fixedly connected to the inner bottom of the second slot. The top of the third spring is fixedly connected with a sliding plate. One side of the lower surface of the sliding plate is fixedly connected with a second rack. The second rack is located directly above the second gear. The second rack and the second gear are meshed with each other.

[0012] Further, the trigger component includes first slots opened on both sides of the upper surface of the fixed mold. The front and rear sides of the inner surface of the first slot are slidably connected with trapezoidal blocks. The top of the trapezoidal block is fixedly connected with a top rod. One side of the first slot penetrates and is slidably connected with a rectangular frame. One side of the rectangular frame is fixedly connected with a second spring.

[0013] Further, one side of the rectangular frame extends into the interior of the second slot and contacts the bottom of the sliding plate. The trapezoidal block is located inside the rectangular frame. The inner side of the rectangular frame contacts the hypotenuse of the trapezoidal block. The top of the top rod extends out of the interior of the first slot. The second gear is in a stretched state.

[0014] Further, an ejection component for pushing the material is provided inside the fixed mold. The ejection component includes fixing plates fixed to both sides of the top of the moving mold and a through groove opened in the middle of the interior of the fixed mold. The lower surface of the fixing plate is fixedly connected with an L-shaped plate. The upper surface of the L-shaped plate is hinged with a first hinge plate. A sliding rod is slidably connected inside the through groove. The upper surface of the sliding rod is fixedly connected with a support rod. The top of the support rod is fixedly connected with a push plate. Both sides of the sliding rod are fixedly connected with mounting plates. A limiting component is provided on the upper surface of the mounting plate.

[0015] Further, the limiting component includes a semi-circular ring fixed to one side of the upper surface of the mounting plate and a second hinge plate hinged to the other side of the upper surface of the mounting plate. A fourth spring is sleeved on the outer surface of the semi-circular ring.

[0016] Furthermore, one side of the semi-circular ring penetrates through the inside of the second hinge plate, the support rod penetrates through the inside of the fixed mold, and a storage groove adapted to the push plate is opened at the middle of the upper surface of the fixed mold.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this solution, by setting an adaptive component, under the cooperation of the first rack and the first gear, it is ensured that the two first limit strips move the same distance above the fixed mold, avoiding the offset of the aluminum alloy material before bending and forming, and avoiding the need to frequently replace different types of molds during bending and forming, avoiding production interruption, effectively improving production efficiency, effectively saving costs in the scenario of multi-variety and small-batch customized production, and under the action of the first spring, the two connecting rods will be pulled closer to each other, so that the two first limit strips extrude and fix the plate or pipe, further ensuring the stability during the bending and forming of the plate or pipe, effectively improving the processing accuracy, and reducing the manual adjustment operation of the two first limit strips to avoid the generation of errors.

[0018] 2. In this solution, by setting a synchronization component, under the cooperation of the fixed block and the hollow rod, when the two first limit strips move, they synchronously drive the second limit strip to move, ensuring that the displacement distance between the two is the same, reducing the steps of adjusting the movement of the two second limit strips, not only reducing the generation of errors, but also effectively improving the efficiency, making the mold have an adaptive function.

[0019] 3. In this solution, by setting a positioning component, the aluminum alloy material drives the trapezoidal block to move downward through the ejector rod. Under the action of the inclined surface of the trapezoidal block and the rectangular frame, the rectangular frame will be pushed into the inside of the first slot. When the rectangular frame completely moves away from below the slide plate, under the contraction action of the third spring, the slide plate moves downward rapidly, driving the second rack to contact and mesh with the second gear, so that the second gear and the rotating shaft are fixed, thereby fixing the first gear, making the two first racks unable to move anymore, thus ensuring that the first limit strip is fixed above the fixed mold. During the subsequent press bending and forming, there is no need to adjust the first limit strip multiple times, effectively improving the practicability of the equipment.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 8 , an aluminum alloy material bending machine, including a base 1, support frames 2 are fixedly connected to the four corners of the upper surface of the base 1, a hydraulic rod 3 is fixedly connected to the top of the support frame 2, a moving die 4 is fixedly connected to the output end of the hydraulic rod 3, a fixed die 5 is fixedly connected to the middle of the upper surface of the base 1, and an adaptive component 6 for adapting to aluminum alloy materials of different widths is arranged on both sides of the fixed die 5.

[0024] Such as Figures 3 - 5As shown in the figure, the adaptive component 6 includes a first chute 61 opened at the top of the fixed mold 5 and a rotating shaft 64 rotatably connected to one side of the fixed mold 5. A first limiting strip 62 is slidably connected inside the first chute 61. A first gear 63 is fixedly connected to one side of the rotating shaft 64. A connecting rod 65 is fixedly connected to one side of the first limiting strip 62. A first rack 66 is fixedly connected to the bottom of the connecting rod 65. A first spring 67 is fixedly connected to one side of the connecting rod 65.

[0025] There are four first limiting strips 62. The first limiting strips 62 are grouped in pairs on the same side. One first limiting strip 62 is slidably connected inside two first limiting strips 62. The first spring 67 is located between the two connecting rods 65. One side of the first limiting strip 62 is provided with an inclined surface. The tooth surfaces of the two first racks 66 face each other, one on top and the other at the bottom. The first gear 63 is located between the two first racks 66 and meshes with them.

[0026] When bending and forming plates or pipes of different widths, in order to avoid the need to frequently replace the mold, two first limiting strips 62 that can change with the width of the aluminum alloy plate or pipe are provided. When bending and forming the aluminum alloy plate or pipe, place the pipe between the two first limiting strips 62 and squeeze it downward. The aluminum alloy plate or pipe contacts and slides with the inclined surface on the first limiting strip 62, pushing the two first limiting strips 62 away from each other. The two first limiting strips 62 drive the two first racks 66 away from each other through the connecting rod 65. The two connecting rods 65 simultaneously stretch the first spring 67. The two first racks 66 move relative to each other. The two first racks 66 simultaneously drive the first gear 63 to rotate. Since both of the two first racks 66 mesh with the first gear 63, the displacement distances of the two connecting rods 65 are the same, effectively ensuring that the moving distances of the two first limiting strips 62 above the fixed mold 5 are the same. When the aluminum alloy material completely enters the inside of the first limiting strips 62, it can effectively ensure that the aluminum alloy plate or pipe is directly above the fixed mold 5, avoiding the offset of the aluminum alloy plate or pipe before bending and forming, avoiding the need to frequently replace different types of molds during bending and forming, avoiding production interruption, effectively improving production efficiency, effectively saving costs in the scenario of multi-variety and small-batch customized production, meeting various manufacturing requirements, and the stretched first spring 67 will pull the two connecting rods 65 closer to each other. Through the transmission of force, the two first limiting strips 62 are close to each other, enabling the two first limiting strips 62 to squeeze and fix the aluminum alloy plate or pipe, further ensuring the stability during the bending and forming of the aluminum alloy plate or pipe, effectively improving the processing accuracy, reducing the manual adjustment operation of the two first limiting strips 62, and avoiding the generation of errors.

[0027] As Figures 4 - 5As shown in the figure, a synchronous component 68 for adapting to the width of aluminum alloy materials is provided on the lower surface of the moving mold 4. The synchronous component 68 includes two second limit bars 681 sliding on the lower surface of the moving mold 4, a hollow rod 683 fixed to the top of the connecting rod 65, and two slots 684 opened on both sides of the upper surface of the moving mold 4. A fixed block 682 is fixedly connected to one side of the second limit bar 681.

[0028] One side of the fixed block 682 extends into the interior of the hollow rod 683. The hollow rod 683 and the fixed block 682 are slidably adapted to each other. The top of the hollow rod 683 penetrates through the interior of the slot 684. The second limit bar 681 and the first limit bar 62 are adapted to each other.

[0029] When adjusting the two first limit bars 62 on the fixed mold 5, the second limit bars 681 on the moving mold 4 need to be adjusted synchronously. Repeatedly adjusting the distance between the two second limit bars 681 on the moving mold 4 results in low production efficiency and a high probability of errors. Therefore, initially, when the two connecting rods 65 move away from each other, they will synchronously drive the two hollow rods 683 to move away from each other. The two hollow rods 683 will drive the second limit bars 681 to move synchronously through the fixed blocks 682, so as to ensure that the two first limit bars 62 drive the second limit bars 681 to move synchronously when moving, ensuring that the displacement distances between them are the same, reducing the steps of adjusting the movement of the two second limit bars 681, not only reducing the generation of errors, but also effectively improving the efficiency, enabling the mold to have an adaptive function.

[0030] During extrusion and bending forming, the fixed block 682 will move up and down synchronously with the moving mold 4. The fixed block 682 will move up and down inside the hollow rod 683, thus not hindering the normal movement of the moving mold 4, and the equipment can work normally. At the same time, when the hollow rod 683 moves left and right, the hollow rod 683 is located inside the slot 684. Similarly, when the hollow rod 683 moves, it will move inside the slot 684, thus ensuring the normal movement of the slot 684.

[0031] As Figure 5 and Figure 7 shown, a positioning component 69 for positioning the two first limit bars 62 is provided inside the fixed mold 5. The positioning component 69 includes trigger components provided on both sides of the top of the fixed mold 5, second slots 696 opened on both sides inside the fixed mold 5, and a second gear 698 fixed to the outer surface of the rotating shaft 64. A third spring 697 is fixedly connected to the inner bottom of the second slot 696. The top of the third spring 697 is fixedly connected to a sliding plate 699. One side of the lower surface of the sliding plate 699 is fixedly connected to a second rack 6910. The second rack 6910 is located directly above the second gear 698. The second rack 6910 and the second gear 698 are meshed with each other.

[0032] The triggering component includes first slots 691 opened on both sides of the upper surface of the fixed mold 5. The front and rear sides of the inner surface of the first slot 691 are slidably connected with trapezoidal blocks 692. The top of the trapezoidal block 692 is fixedly connected with a ejector rod 693. One side of the first slot 691 penetrates and is slidably connected with a rectangular frame 695. One side of the rectangular frame 695 is fixedly connected with a second spring 694.

[0033] One side of the rectangular frame 695 extends into the interior of the second slot 696 and contacts the bottom of the sliding plate 699. The trapezoidal block 692 is located inside the rectangular frame 695. The inner side of the rectangular frame 695 contacts the hypotenuse of the trapezoidal block 692. The top of the ejector rod 693 extends out of the interior of the first slot 691. The second gear 698 is in a stretched state.

[0034] However, after the bending forming of an aluminum alloy plate or pipe for the first time, due to the lack of limiting effect of the two first limiting strips 62, the two first limiting strips 62 will automatically reset under the pulling of the first spring 67, resulting in the need to re-adjust the first limiting strips 62 during the next press bending forming. Although it is relatively convenient to adjust the two first limiting strips 62, it will still increase a certain amount of labor for the operator. Therefore, it is necessary to ensure that the two first limiting strips 62 are in a fixed state when pressing and bending forming the same batch of aluminum alloy plates or pipes. When the aluminum alloy plate or pipe is placed between the two first limiting strips 62, the aluminum alloy plate or pipe will contact the ejector rod 693. As the aluminum alloy plate or pipe descends, the ejector rod 693 is pressed downward and moves. The trapezoidal block 692 moves synchronously with the ejector rod 693. Since the inclined surface of the trapezoidal block 692 contacts the inner side of the rectangular frame 695, the trapezoidal block 692 moves downward, and the rectangular frame 695 will be pushed into the interior of the first slot 691. At the same time, the second spring 694 is compressed, and the rectangular frame 695 gradually moves away from below the sliding plate 699. As the aluminum alloy plate or pipe continues to descend, the trapezoidal block 692 continues to move inside the rectangular frame 695, and the rectangular frame 695 continues to move away from below the sliding plate 699. When the rectangular frame 695 completely moves away from below the sliding plate 699, the sliding plate 699 quickly moves downward under the contraction of the third spring 697, driving the second rack 6910 to contact and mesh with the second gear 698, so that the second gear 698 and the rotating shaft 64 are fixed, thereby fixing the first gear 63, making the two first racks 66 unable to move anymore, thus ensuring that the first limiting strip 62 is fixed above the fixed mold 5. In subsequent press bending forming, there is no need to repeatedly adjust the first limiting strip 62, effectively improving the practicality of the equipment; After the bending forming of all aluminum alloy plates or pipes is completed, at this time, the first limiting strip 62 needs to be reset. Push the sliding plate 699 to move upward inside the second slot 696. At this time, pull the ejector rod 693 to drive the trapezoidal block 692 to move upward. Under the thrust of the second spring 694, the rectangular frame 695 slides downward below the sliding plate 699 to support the sliding plate 699, so that the second rack 6910 and the second gear 698 are separated from each other, and the first limiting strip 62 can be reset under the action of the first spring 67.

[0035] As Figure 2 and Figure 8 As shown, an ejection assembly 7 for pushing materials is arranged inside the fixed mold 5. The ejection assembly 7 includes a fixing plate 71 fixed to the tops of both sides of the moving mold 4 and a through groove 74 opened in the middle of the inside of the fixed mold 5. The lower surface of the fixing plate 71 is fixedly connected with an L-shaped plate 72. The upper surface of the L-shaped plate 72 is hinged with a first hinged plate 73. A sliding rod 75 is slidably connected inside the through groove 74. The upper surface of the sliding rod 75 is fixedly connected with a support rod 76. The top of the support rod 76 is fixedly connected with a push plate 77. Both sides of the sliding rod 75 are fixedly connected with mounting plates 78, and a limiting component is arranged on the upper surface of the mounting plates 78.

[0036] The limiting component includes a semi-circular ring 710 fixed to one side of the upper surface of the mounting plate 78 and a second hinged plate 79 hinged to the other side of the upper surface of the mounting plate 78. A fourth spring 711 is sleeved on the outer surface of the semi-circular ring 710.

[0037] One side of the semi-circular ring 710 penetrates through the inside of the second hinged plate 79. The support rod 76 penetrates through the inside of the fixed mold 5. A storage groove adapted to the push plate 77 is opened in the middle of the upper surface of the fixed mold 5.

[0038] After stamping is completed, it is necessary to manually remove the aluminum alloy plate or pipe from between the two first limiting strips 62. Since the aluminum alloy plate or pipe will deform during bending forming, there will be a certain extrusion force between it and the two first limiting strips 62, resulting in a certain amount of force required to remove the plate or pipe from between the first limiting strips 62. At the same time, when the staff's hands are exposed between the moving mold 4 and the fixed mold 5 for a long time, it will increase a certain degree of danger; When placing an aluminum alloy sheet or pipe between two first limiting strips 62, start the hydraulic rod 3 to drive the moving die 4 downward. The moving die 4 drives the first hinge plate 73 downward through the fixing plate 71 and the L-shaped plate 72. When the first hinge plate 73 moves downward, it will contact the second hinge plate 79. After being blocked, the first hinge plate 73 will rotate around the hinge until the first hinge plate 73 passes through the second hinge plate 79. When the bending forming is completed, the hydraulic rod 3 drives the moving die 4 upward, driving the first hinge plate 73 upward through the fixing plate 71 and the L-shaped plate 72. When the first hinge plate 73 contacts the lower part of the second hinge plate 79, the first hinge plate 73 cannot flip downward due to the block of the horizontal plate of the L-shaped plate 72, so that the first hinge plate 73 drives the two second hinge plates 79 upward, and synchronously moves upward through the mounting plate 78 and the sliding rod 75. The support rod 76 pushes the aluminum alloy sheet or pipe between the two first limiting strips 62 upward through the push plate 77, so that the aluminum alloy sheet or pipe can be quickly removed from the fixed die 5, reducing the time for the staff's hand to be exposed between the moving die 4 and the fixed die 5. When the sliding rod 75 moves to the top of the through groove 74 and cannot move upward continuously, at this time, the first hinge plate 73 continues to push the second hinge plate 79, and the second hinge plate 79 slides a certain angle outside the semi-circular ring 710 around the hinge point until the first hinge plate 73 passes through the second hinge plate 79. Thus, after the bending forming, the aluminum alloy sheet or pipe can be automatically moved out from between the two first limiting strips 62 by the driving force of the movement of the moving die 4, simplifying the operation steps.

[0039] Usage method: First, place the sheet or pipe of the aluminum alloy material between two first limiting strips 62 and squeeze downward. The aluminum alloy material contacts and slides with the inclined surfaces on the first limiting strips 62, pushing the two first limiting strips 62 away from each other. The two first limiting strips 62 drive the two first racks 66 away from each other through the connecting rods 65. The two connecting rods 65 simultaneously stretch the first spring 67. The two first racks 66 move relative to each other, and the two first racks 66 simultaneously drive the first gear 63 to rotate. Since both of the two first racks 66 are meshed with the first gear 63, the displacement distances of the two connecting rods 65 are the same, effectively ensuring that the moving distances of the two first limiting strips 62 above the fixed die 5 are the same. When the aluminum alloy sheet or pipe completely enters the interior of the first limiting strips 62, it can be effectively ensured that the aluminum alloy sheet or pipe is directly above the fixed die 5. When the two connecting rods 65 move away from each other, they will synchronously drive the two hollow rods 683 to move away from each other. The two hollow rods 683 will drive the second limiting strip 681 to move synchronously through the fixed block 682, so as to ensure that the two first limiting strips 62 drive the second limiting strip 681 to move synchronously when moving, ensure that the displacement distance between the two is the same, reduce the steps of adjusting the movement of the two second limiting strips 681, not only reduce the generation of errors, and with the cooperation of the components of the positioning assembly 69, when placing the aluminum alloy sheet or pipe between the two first limiting strips 62, the rotating shaft 64 can be automatically fixed, avoiding subsequent repeated adjustment of the first limiting strip 62; The moving die 4 drives the first hinge plate 73 to move downward through the fixing plate 71 and the L-shaped plate 72. When the first hinge plate 73 moves downward, it will contact the second hinge plate 79. After being blocked, the first hinge plate 73 will rotate around the hinge until the first hinge plate 73 passes through the second hinge plate 79. When the bending forming is completed, the hydraulic rod 3 drives the moving die 4 to move upward, driving the first hinge plate 73 to move upward through the fixing plate 71 and the L-shaped plate 72. When the first hinge plate 73 contacts the lower part of the second hinge plate 79, the first hinge plate 73 cannot be turned downward due to the block of the horizontal plate of the L-shaped plate 72, so that the first hinge plate 73 drives the two second hinge plates 79 to move upward, and synchronously move upward through the mounting plate 78 and the slide rod 75. The support rod 76 pushes the pipe between the first limiting strips 62 upward through the push plate 77, so that the pipe or plate can be quickly removed from the fixed die 5.

[0040] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
