Description

Technical Field

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

[0002] Aluminum profile bending, a key process in aluminum processing, involves applying pressure using specific equipment to precisely bend the aluminum profile into a predetermined shape. This process is widely used in various fields such as construction, industrial equipment, and electronic products, playing a crucial role in the final form and performance of the products.

[0003] Patent publication number CN219025542U discloses an aluminum profile bending device. The device can bend the aluminum profile by pressing the bending blade against the forming plate. After the bending operation is completed, the controller turns on the motor to drive the lead screw to rotate. The two lead screws in opposite directions can drive the moving plate to move relative to each other, which can drive the forming plate to move, thereby allowing the aluminum profile to be detached from the aluminum profile, making the removal of the aluminum profile more convenient.

[0004] However, in practical applications, this solution has also revealed some problems. For example, when the forming plate moves, the aluminum profile may fall into the gap between the two forming plates, which not only increases the difficulty of retrieval but may also cause unnecessary damage to the aluminum profile. In addition, the device is inconvenient in terms of replacing the forming blade and forming plate, limiting its adaptability to different bending angle requirements and making it difficult to meet diverse processing needs. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an aluminum profile bending machine.

[0006] The technical solution is as follows: An aluminum profile bending machine includes a base plate, a vertical plate, a placement table, a bending module, a pressing and bending component, a limiting component, and an ejection component. The vertical plate is fixedly connected to the top left side of the base plate, and the placement table is fixedly connected to the top of the base plate. The bending module is placed on the top of the placement table. The pressing and bending component for pressing and bending the workpiece is provided on the vertical plate. The limiting component is provided on both the bending module and the placement table for limiting and fixing the bending module. The ejection component for ejecting the bent workpiece from the bending module is provided on the base plate.

[0007] Furthermore, the bending assembly includes an I-beam, sliding rods, a mounting plate, a clamping block, a bending block, and a hydraulic cylinder. An I-beam is fixedly connected to the upper part of the upright plate. Sliding rods are slidably arranged on both sides of the I-beam. A mounting plate is fixedly connected between the lower ends of the two sliding rods. A clamping block is fixedly connected to the bottom of the mounting plate. A bending block is slidably arranged on the clamping block. A hydraulic cylinder is installed in the middle of the I-beam. The piston rod end of the hydraulic cylinder is fixedly connected to the mounting plate.

[0008] Furthermore, the limiting component includes a fixing block, a fixing seat, a guide rod, a hand-tightened bidirectional screw, a slider, and a limiting block. Fixing blocks are fixedly connected to the left and right sides of the bottom of the bending module. Both fixing blocks can penetrate the table panel of the placement platform. Fixing seats are fixedly connected to the left and right sides of the bottom of the table panel. A guide rod is fixedly connected between the rear sides of the two fixing seats. A hand-tightened bidirectional screw is rotatably connected between the front sides of the two fixing seats. Sliders are slidably arranged on the left and right sides of the guide rod. The hand-tightened bidirectional screw passes through the two sliders and is threaded into them. A limiting block is embedded and fixedly connected to the side of the two sliders that are close to each other. Limiting grooves are opened on the sidewalls of the two fixing blocks that are far apart from each other. The limiting blocks can be inserted into the adjacent limiting grooves.

[0009] Furthermore, the ejection assembly includes an electric push rod, a horizontal plate, and a top rod. Two electric push rods are embedded and spaced apart on the base plate. A horizontal plate is fixedly connected between the telescopic rod ends of the two electric push rods. Top rods are symmetrically fixedly connected to the left and right sides of the top of the horizontal plate. The top rods can penetrate the table panel of the placement platform. Four through holes are opened at intervals on the bending module. The four top rods can extend upward from the adjacent through holes respectively.

[0010] Furthermore, it also includes rubber blocks, with rubber blocks fixedly connected to the top of each of the four top rods.

[0011] Furthermore, it also includes a reinforcing plate, with the reinforcing plate fixedly connected to the top of the horizontal plate.

[0012] The beneficial effects are as follows: After the workpiece is bent, the electric push rod pushes the top rod to lift the workpiece, preventing the workpiece from getting stuck in the bending module, making it easy to pick up and reducing damage. When replacing the bending block, the old block can be slid off and replaced with the required model. When replacing the bending module, the module can be replaced by turning the hand-tightened two-way screw to release and reposition the fixing block, thus facilitating adjustment and meeting the requirements of different bending angles, adapting to diversified processing.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example: An aluminum profile bending machine, such as Figures 1-4 As shown, it includes a base plate 1, a vertical plate 2, a placement platform 21, a bending module 22, a bending assembly, a limiting assembly, and an ejection assembly. The vertical plate 2 is welded and fixed to the top left of the base plate 1, and the placement platform 21 is welded and fixed to the top of the base plate 1. The bending module 22 is placed in the middle of the top of the placement platform 21. The bending assembly for pressing and bending the workpiece is provided on the vertical plate 2. The bending module 22 and the placement platform 21 are jointly provided with a limiting assembly for limiting and fixing the bending module 22. The ejection assembly for ejecting the bent workpiece from the bending module 22 is provided on the base plate 1.

[0020] like Figure 1 As shown, the bending assembly includes an I-beam plate 31, sliding rods 32, mounting plate 33, clamping block 34, bending block 35, and hydraulic cylinder 36. The I-beam plate 31 is fixedly connected to the upper part of the upright plate 2. Sliding rods 32 are slidably arranged on both sides of the I-beam plate 31. The mounting plate 33 is welded and fixed between the lower ends of the two sliding rods 32. The clamping block 34 is fixed to the bottom of the mounting plate 33 by bolts. The bending block 35 is slidably arranged on the clamping block 34. There is friction between the bending block 35 and the clamping block 34. This friction is sufficient to prevent the bending block 35 from sliding arbitrarily on the clamping block 34. The hydraulic cylinder 36 is fixedly installed in the middle of the I-beam plate 31 by bolts. The piston rod end of the hydraulic cylinder 36 is fixedly connected to the mounting plate 33. The bending module 22 has a groove that cooperates with the bending block 35.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, the limiting assembly includes a fixing block 41, a fixing seat 42, a guide rod 43, a hand-tightened bidirectional screw 44, a slider 45, and a limiting block 46. Fixing blocks 41 are welded and fixed on both the left and right sides of the bottom of the bending module 22. Both fixing blocks 41 can penetrate the table panel of the placement platform 21. Fixing seats 42 are welded and fixed on both the left and right sides of the bottom of the table panel of the placement platform 21. A guide rod 43 is welded and fixed between the rear sides of the two fixing seats 42. A hand-tightened bidirectional screw 44 is rotatably connected between the front sides of the two fixing seats 42. Sliders 45 are slidably arranged on both the left and right sides of the guide rod 43. The hand-tightened bidirectional screw 44 passes through the two sliders 45 and is threaded into them. A limiting block 46 is embedded and fixedly connected on the side of the two sliders 45 that are close to each other. A limiting groove 47 is opened on the side wall of the two fixing blocks 41 that are far apart from each other. The limiting block 46 can be inserted into the adjacent limiting groove 47.

[0022] like Figure 2 and Figure 3 As shown, the ejector assembly includes an electric push rod 51, a horizontal plate 52, and a push rod 53. Two electric push rods 51 are embedded and spaced on the base plate 1. The horizontal plate 52 is fixedly connected between the telescopic rod ends of the two electric push rods 51. The top left and right sides of the top of the horizontal plate 52 are symmetrically welded and fixed with push rods 53. The push rods 53 can penetrate the table panel of the placement platform 21. Four through holes 54 are opened at intervals on the bending module 22. The four push rods 53 can extend upward from the adjacent through holes 54 respectively.

[0023] In operation, the operator first places the workpiece to be bent into the groove on the bending module 22. Then, the hydraulic cylinder 36 is activated, and its piston rod extends. Guided by the sliding rod 32, the piston rod pushes the mounting plate 33 downwards, thereby causing the bending block 35 to apply pressure to the workpiece, bending it downwards along the groove of the bending module 22, thus completing the bending process. After bending, the operator retracts the piston rod of the hydraulic cylinder 36. Simultaneously, two electric push rods 51 are activated, their telescopic rods extending synchronously, pushing four push rods 53 upwards via the cross plate 52. As the push rods 53 move upwards, they lift the workpiece from the groove of the bending module 22, effectively preventing it from getting stuck and difficult to remove. When bending at different angles is required, the operator slides the currently used bending block 35 off the clamping block 34 and replaces it with the required type. Next, the hand-operated double-sided screw 44 is turned. As the screw rotates, the two sliders 45, guided by the guide rod 43, move away from each other. This movement causes the two limiting blocks 46 to disengage from the limiting grooves 47 on the adjacent fixing blocks 41, thus releasing the limiting effect on the fixing blocks 41. At this point, the worker can remove the bending module 22 and replace it. When replacing the new bending module 22, it is necessary to ensure that the through hole 54 on it is aligned with the top rod 53. Then, the fixing block 41 on the replaced bending module 22 is passed through the table panel of the placement table 21. Finally, the worker reverses the direction of the hand-operated double-sided screw 44, causing the limiting block 46 to re-insert into the limiting groove 47 on the fixing block 41, completing the limiting effect on the fixing block 41. In this way, the bending block 35 and the bending module 22 can be replaced, facilitating bending processing of the workpiece at different angles.

[0024] like Figure 3 As shown, it also includes rubber blocks 6, and the tops of the four top rods 53 are all glued and fixed with rubber blocks 6.

[0025] By setting a rubber block 6 on the top of the push rod 53, it is possible to effectively prevent the push rod 53 from scratching the surface of the workpiece when it lifts the workpiece.

[0026] like Figure 2 As shown, it also includes a reinforcing plate 7, which is integrally formed and fixed to the top of the horizontal plate 52.

[0027] By setting the reinforcing plate 7, the strength of the horizontal plate 52 can be enhanced, preventing it from bending during the ejection of the workpiece.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
