Description

Technical Field

[0001] The present application relates to the technical field of bending machines, and more particularly to an aluminum bending machine with a safety protection function. Background Art

[0002] Aluminum processing uses plastic processing methods to process aluminum billets into finished products. The main methods include rolling, extrusion, stretching, and forging, etc.

[0003] However, during the aluminum processing, a common problem is that it is difficult for the aluminum material to be separated from the lower die during processing. This is usually due to the relatively large frictional force and adhesion force generated between the aluminum material and the die during processing. Currently, a compression spring is usually used to drive the panel to rise, so that the panel drives the ejector rod to rise, facilitating the rising ejector rod to eject the aluminum plate in the lower die, and facilitating the user to take out the formed aluminum plate.

[0004] For example, in the prior art, the Chinese utility model patent with the authorization publication number CN217370172U discloses "a bending machine for aluminum processing", which includes a workbench. The upper surface of the workbench is fixedly connected with a U-shaped plate. The lower surface of the U-shaped plate is fixedly connected with a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected with an upper die. The upper surface of the workbench is fixedly connected with a lower die. An activity device is arranged in the lower die. An aluminum plate is placed on the upper surface of the lower die. A groove is opened on the upper surface of the workbench. Two connecting blocks are arranged in the groove. The left inner wall of the groove is fixedly connected with a limiting rod.

[0005] However, although this bending machine has certain convenience in taking out the formed aluminum plate, there are still some problems in actual use. The most prominent one is the disassembly problem of the upper die and the lower die. Since the upper die and the lower die are connected to the workbench and the hydraulic cylinder in a fixed connection manner, it is not convenient to disassemble them in actual operation. This makes the bending machine unable to fully exert its processing ability when dealing with aluminum plates of different models.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed implementation manners

[0024] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 4 drawings.

[0025] The embodiment of the present application discloses an aluminum bending machine with a safety protection function. Referring to Figures 1 - 4 , an aluminum bending machine with a safety protection function includes a workbench 1, a U-shaped protective plate 3 is fixed on the top of the workbench 1, support legs 2 are fixed at the four corners of the bottom, a detachable lower die 6 is further installed on the top of the workbench 1, a hydraulic cylinder 4 is fixed on the top surface of the U-shaped protective plate 3, and the output end of the hydraulic cylinder 4 penetrates through the U-shaped protective plate 3 and is installed with a detachable upper die 5;

[0026] Two threaded rods 8 are fixed to the bottom of the lower die 6, and the two threaded rods 8 penetrate through the workbench 1 and are installed with nuts through threads. A die pressing groove 7 is also opened on the lower die 6. Two screws 17 are fixed to the top of the upper die 5. Cones 18 are installed on the outer walls of the two screws 17 through threads. Knobs 19 are fixed to the top surfaces of the cones 18. A fixing plate 20 is fixed to the output end of the hydraulic cylinder 4. Two conical grooves 21 for the cones 18 to be inserted into are penetrated and opened on the fixing plate 20. During use, first, by rotating the knob 19, the cone 18 is driven to rotate on the outer wall of the screw 17, and then the cone 18 moves along the axis direction of the screw 17 until the cone 18 is completely inserted into the conical groove 21, thus realizing the fixed connection between the upper die 5 and the hydraulic cylinder 4. This connection method is not only convenient and fast, but also stable and reliable, and can effectively prevent the upper die 5 from loosening or falling off during use, improving the safety and stability of the aluminum bending machine. When it is necessary to replace the upper die 5 of different models, just rotate the knob 19 in the reverse direction to make the cone 18 withdraw from the conical groove 21, and the upper die 5 can be easily disassembled. By rotating the nut on the threaded rod 8 counterclockwise and removing the nut from the threaded rod 8, the lower die 6 can be easily disassembled. This detachable design enables the aluminum bending machine to flexibly handle aluminum plates of different models, improving its processing capacity. At the same time, since both the upper die 5 and the lower die 6 can be disassembled through simple operations, it is also convenient for users to clean and maintain the die, extending the service life of the aluminum bending machine.

[0027] Refer to Figure 1 and Figure 3, two sliding grooves 9 are provided at the bottom of the workbench 1 directly below the die pressing groove 7, a placing groove 10 is provided at the top of the workbench 1 above the two sliding grooves 9, a through hole 11 is provided at the bottom of the lower die 6 below the die pressing groove 7, and the sliding grooves 9, the placing groove 10, the through hole 11 and the die pressing groove 7 communicate with each other. The workbench 1 is slidably connected with guide rods 12 through the two sliding grooves 9. The two guide rods 12 penetrate through the placing groove 10, the through hole 11 and the die pressing groove 7 and are fixed with a support plate 13. A return spring 14 is sleeved on the outer wall of each of the two guide rods 12. The return spring 14 is located between the support plate 13 and the bottom of the placing groove 10. When bending aluminum materials, the aluminum material plate is placed on the support plate 13 and bent by the pressing of the upper die 5 and the lower die 6. During the pressing process, the support plate 13 is subjected to pressure and slides downward along the guide rod 12 in the sliding groove 9, compressing the return spring 14 at the same time. In this way, the support plate 13 can provide a certain buffering effect to avoid excessive impact force on the aluminum material plate during the bending process, thereby protecting the aluminum material plate from being damaged. When the processing is completed, the upper die 5 and the lower die 6 are separated, and the return spring 14 will push the support plate 13 to slide upward along the guide rod 12 under the action of its own elastic force until the support plate 13 returns to the initial position. In this way, it is not only convenient to take out the bent aluminum material, but also convenient for the placement and processing of the next aluminum material plate. In addition, the communicating design of the sliding groove 9, the placing groove 10, the through hole 11 and the die pressing groove 7 makes the whole structure more compact, reduces the volume of the aluminum material bending machine, and also facilitates the installation and maintenance of components such as the support plate 13, the guide rod 12 and the return spring 14.

[0028] Refer to Figure 3 , two U-shaped storage plates 15 are also installed on the top surface of the lower die 6 by bolts, and inclined groove 16 is provided on one side of each of the two U-shaped storage plates 15; the design of the inclined groove 16 enables the aluminum material plate to slide into the U-shaped storage plate 15 more smoothly when placed, improving work efficiency. At the same time, the presence of the U-shaped storage plate 15 provides a stable support platform for the aluminum material plate, ensuring stability and accuracy during the bending process.

[0029] Refer to Figure 1 , a number of reinforcing ribs 24 are fixed on both inner sides of the U-shaped protection plate 3; the stability of the U-shaped protection plate 3 is increased, making it not easy to bend.

[0030] Refer to Figure 1 , two sliding rods 23 are fixed on the top surface of the upper die 5, and the two sliding rods 23 penetrate through the U-shaped protection plate 3; the stability of the upper die 5 during movement is increased, making it not easy to shake.

[0031] Refer to Figure 1 and Figure 4 , a sleeve 22 is fixed on the top surface of the upper die 5; the stability of the upper die 5 during installation can be further increased, making it not easy to shake.

[0032] Referring to Figure 4 , both the fixing plate 20 and the screw rod 17 are made of metal, which are not easily broken or bent, thus extending their service life.

[0033] The implementation principle of an aluminum bending machine with a safety protection function in an embodiment of the present application is as follows: When performing aluminum bending processing, the aluminum plate is placed on the support plate 13. The hydraulic cylinder 4 is started to press the upper die 5 and the lower die 6 for bending. During the pressing process, the support plate 13 is under pressure and will slide downward along the guide rod 12 in the sliding groove 9, while compressing the return spring 14. In this way, the support plate 13 can provide a certain buffering effect to avoid excessive impact force on the aluminum plate during the bending process, thereby protecting the aluminum plate from being damaged. When the processing is completed, the upper die 5 and the lower die 6 are separated, and the return spring 14 will push the support plate 13 to slide upward along the guide rod 12 under its own elastic force until the support plate 13 returns to its initial position. In this way, it is not only convenient to take out the bent aluminum, but also convenient for the placement and processing of the next aluminum plate;

[0034] When it is necessary to replace the upper die 5 of different models, just rotate the knob 19 in the reverse direction to make the cone 18 withdraw from the cone groove 21, and then the upper die 5 can be easily disassembled. By rotating the nut on the threaded rod 8 counterclockwise and removing the nut from the threaded rod 8, the lower die 6 can be easily disassembled. This detachable design enables the aluminum bending machine to flexibly handle aluminum plates of different models, improving its processing ability. At the same time, since both the upper die 5 and the lower die 6 can be disassembled through simple operations, it is also convenient for users to clean and maintain the dies, extending the service life of the aluminum bending machine.
