Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, specifically to an aluminum plate bending machine. Background Technology

[0002] Aluminum sheet is a common type of metal sheet. It refers to a rectangular sheet made by rolling aluminum ingots. It is divided into pure aluminum sheet, alloy aluminum sheet, thin aluminum sheet, and medium-thick aluminum sheet. Aluminum sheet refers to aluminum materials with a thickness of 0.2mm to 500mm, a width of 200mm or more, and a length of 16m or less. It is widely used in various fields. In the deep processing of aluminum sheet, bending is usually required.

[0003] For example, an aluminum plate bending machine with application number CN202323510272.X and authorization announcement date of 20241015 relates to the field of aluminum plate processing technology. This utility model includes a folding box, with connecting plates fixedly connected to both ends of the folding box. A pair of through-holes are provided on the outer wall of the connecting plates. A first folding plate is provided on one side of the upper end face of the folding box, and a second folding plate is provided on the other side. Multiple first limiting blocks are fixedly connected to the end face of the first folding plate near the second folding plate. By sequentially and alternately installing the first and second limiting blocks between the first and second folding plates, and by pressing the aluminum plate with an extrusion strip, the first and second folding plates rotate around a rotating shaft under the pressure of the extrusion strip. The multiple first and second limiting blocks intersect sequentially, supporting the aluminum plate and preventing it from falling into the folding box. The first and second folding plates flip to bend the aluminum plate. The operation is simple and requires no manual operation by staff.

[0004] When bending the edges of large aluminum plates into right angles using a bending machine, the aluminum plate must first be placed on a base, then the bending machine is driven to press down and bend the aluminum plate. Afterward, the aluminum plate needs to be manually supported so that one side of the aluminum plate is raised to meet the requirement of bending the edges into right angles. However, this process involves large aluminum plates with heavy weights, which increases the labor intensity of workers and also affects the bending efficiency of the bending machine. Therefore, it is urgent to design an aluminum plate bending machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum plate bending machine to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aluminum plate bending machine includes a frame assembly. Lifting components are provided on both outer walls of the top of the frame assembly. Each lifting component includes a fixed seat. Sliding rods are slidably inserted into both outer walls of the top of the fixed seat, and pressure blocks are bolted to the bottom ends of the two sliding rods. A pressing cylinder is bolted to one outer wall of the top of the fixed seat, and the output end of the pressing cylinder is bolted to the pressure block. The frame assembly includes a box body. Placement grooves are formed on both outer walls of the top of the box body. Two mounting shafts are bolted to one side of the inner wall of the placement groove. The fixed seat is mounted outside the mounting shafts via bearings. Through holes are formed on both sides of the bottom of the inner wall of the placement groove. Two lifting cylinders are bolted to one side of the inner wall of the box body, and the output ends of the lifting cylinders are inserted into the through holes. The output ends of the lifting cylinders are in contact with the fixed seat.

[0008] Furthermore, a groove is provided on one side of the outer wall of the top of the box, and a plug-in groove is provided on one side of the inner wall of the box, and the plug-in groove and the groove are interconnected.

[0009] Furthermore, two lifting cylinders are bolted to one side of the inner wall of the box. A limiting plate is provided inside the groove and is slidably inserted into the insertion slot. The limiting plate is fixedly connected to the output end of the lifting cylinder by bolts.

[0010] Furthermore, a lower mold is provided on one side of the top of the box frame assembly. The lower mold is placed inside the groove, and a slot is provided on the outer wall of one side of the top of the lower mold. The limiting plate is slidably inserted into the slot.

[0011] Furthermore, the outer walls on both sides of the top of the box are bolted with mounting grooves, and two electric rollers are mounted inside the mounting grooves via bearings, with a belt wound between two adjacent electric rollers.

[0012] Furthermore, upper mold components are bolted to both outer walls of the box frame assembly. The upper mold components include mounting brackets, which are bolted to the outer walls of both sides of the box body.

[0013] Furthermore, two hydraulic cylinders are bolted to one side of the outer wall of the mounting bracket, and the output ends of the two hydraulic cylinders are bolted to the mounting housing. An adjusting bolt is mounted to one side of the outer wall of the mounting housing via a bearing, and the output end of the adjusting bolt is threaded to a piston plate, which is slidably connected inside the mounting housing.

[0014] Furthermore, two connecting seats are welded to one side of the outer wall of the mounting shell, and a pressure knife is slidably connected inside the connecting seats. A housing is installed on one side of the outer wall of the mounting shell by bolts, and the housing and the mounting shell are interconnected. Hydraulic oil is stored between the housing and the mounting shell. Two connecting plates are slidably connected inside the housing, and multiple connecting springs are installed between the two connecting plates by bolts. Multiple insertion rods are slidably inserted into one side of the outer wall of the connecting plate, and one end of the insertion rod is inserted into the inside of the connecting seat. The insertion rod is inserted into the pressure knife.

[0015] In the above technical solution, the aluminum plate bending machine provided by this utility model has the following beneficial effects:

[0016] When the upper die bends a large aluminum plate using the lifting components and lifting cylinders, the two corresponding lifting cylinders will be activated. The output end of the lifting cylinder will lift the fixed seat, and the fixed seat will rotate around the mounting shaft under the operation of the lifting cylinder. Then, one side of the aluminum plate held by the lifting components will be lifted up, which meets the requirement that one side of the aluminum plate is lifted during bending. This realizes the automatic processing of aluminum plate bending, reduces the labor intensity of workers, and helps to improve the bending efficiency of the bending machine for aluminum plates.

[0017] With the adjustable bolt, piston plate, connecting spring, connecting plate, and plug rod configured, when the pressure knife needs to be replaced, the adjustable bolt can be rotated. The adjusting bolt will then slide the piston plate inside the mounting housing, and the piston plate will return to its original position. The hydraulic oil inside the mounting housing will no longer be squeezed by the piston plate. Then, under the action of multiple connecting springs, the two connecting plates inside the housing will move closer to each other, and the plug rod will disengage from the connecting seat and no longer restrict the pressure knife. Subsequently, the worker can pull the pressure knife to one side to achieve quick replacement of the pressure knife, reducing the difficulty of disassembling and replacing the pressure knife.

[0018] With the addition of a frame, electric rollers, and belts, the box body is equipped with two sets of conveyor structures consisting of electric rollers and belts. When bending large aluminum plates, both sets of conveyor structures can transport the aluminum plates. In conjunction with the design of two sets of lifting components, the bending of both sides of the aluminum plate can be achieved continuously. Moreover, this process does not require manual assistance, which greatly improves the efficiency of bending aluminum plates. Attached Figure Description

The output end of the lifting cylinder 14 is inserted into the through hole 13. The output end of the lifting cylinder 14 is in contact with the fixed seat 28.

[0031] Specifically, in this embodiment, the assembly includes a frame assembly 1. Lifting components 2 are provided on both outer walls of the top of the frame assembly 1. Each lifting component 2 includes a fixed base 28. Sliding rods 31 are slidably inserted into both outer walls of the top of the fixed base 28. The sliding rods 31 are slidably inserted into the fixed base 28 and can guide the movement of the pressure block 30. Pressure blocks 30 are bolted to the bottom ends of the two sliding rods 31. A pressing cylinder 29 is bolted to one outer wall of the top of the fixed base 28. The pressing cylinder 29 is preferably of model SC20*50. When the pressing cylinder 29 is activated, the pressure block 30 moves inside the fixed base 28, pressing down on the portion of the aluminum plate inside the fixed base 28, thus limiting the edge of the aluminum plate. The output end of the pressing cylinder 29 is bolted to the pressure block 30. The frame assembly 1 includes a box body 5. Both outer walls of the top of the box body 5 are... The device has a mounting groove 6, and two mounting shafts 10 are bolted to one side of the inner wall of the mounting groove 6. The mounting shafts 10 facilitate the installation of the lifting assembly 2 on the housing 5. The fixing seat 28 is mounted on the outside of the mounting shafts 10 via bearings. Through holes 13 are provided on both sides of the bottom of the inner wall of the mounting groove 6. Two lifting cylinders 14 are bolted to one side of the inner wall of the housing 5. The preferred model of the lifting cylinder 14 is SC50*400. When the lifting cylinder 14 is activated, the extended output end of the lifting cylinder 14 will lift the fixing seat 28. The fixing seat 28 will rotate around the mounting shaft 10 under the operation of the lifting cylinder 14. Then, one side of the aluminum plate held by the lifting assembly 2 will be lifted up, which meets the requirement that one side of the aluminum plate is lifted when the aluminum plate is bent by the pressure knife 21. The output end of the lifting cylinder 14 is inserted into the through hole 13, and the output end of the lifting cylinder 14 is in contact with the fixing seat 28.

[0032] This utility model provides an aluminum plate bending machine. When the upper die 4 bends a large aluminum plate, the two corresponding lifting cylinders 14 will be activated. The output end of the lifting cylinder 14 will lift the fixed seat 28. The fixed seat 28 will rotate around the mounting shaft 10 under the operation of the lifting cylinder 14.

The insertion groove 15 and the groove 11 are interconnected. Two lifting cylinders 16 are installed on one side of the inner wall of the box body 5 by bolts. The preferred model of the lifting cylinder 16 is SC30*100. A limiting plate 12 is provided inside the groove 11 and is slidably inserted into the insertion groove 15. When the lifting cylinder 16 is activated, the limiting plate 12 will slide and rise and fall inside the lower mold 3 to satisfy the restriction of the moving aluminum plate or not restrict the aluminum plate. The limiting plate 12 can restrict the aluminum plate sliding on the box body 5. The limiting plate 12 is fixedly connected to the output end of the lifting cylinder 16 by bolts. A lower mold 3 is provided on one side of the top of the box frame assembly 1. The lower mold 3 is placed inside the groove 11. A slot 32 is provided on one side of the top of the lower mold 3. The limiting plate 12 is slidably inserted into the slot 32.

[0034] In another embodiment provided by this utility model, as follows Figure 2-3 As shown, the top two outer walls of the box 5 are bolted with mounting grooves 7, and two electric rollers 9 are mounted inside the mounting grooves 7 by bearings. The electric rollers 9 are preferably conventional models. A belt 8 is wound between two adjacent electric rollers 9. When the electric rollers 9 are started, the electric rollers 9 will start to move in a circular motion with the belt 8. Subsequently, the belt 8 will slide on the box 5 with the aluminum plate.

[0035] In another embodiment provided by this utility model, such as Figure 1 and Figure 4-5As shown, upper mold components 4 are bolted to both outer walls of the frame assembly 1. Each upper mold component 4 includes a mounting bracket 17, which is bolted to both outer walls of the housing 5. Two hydraulic cylinders 18 are bolted to one outer wall of the mounting bracket 17. The preferred model of the hydraulic cylinders 18 is MOB80*200. Mounting housings 19 are bolted to the output ends of the two hydraulic cylinders 18. Adjusting bolts 22 are mounted to one outer wall of the mounting housing 19 via bearings. A piston plate 23 is threaded to the output end of the adjusting bolt 22. The piston plate 23 is made of a sheet metal with a rubber ring and is slidably connected inside the mounting housing 19. Two connecting seats 20 are welded to one outer wall of the mounting housing 19, and a pressure knife 21 is slidably connected inside the connecting seats 20. Multiple pin holes are opened on one side of the pressure knife 21. A housing 24 is bolted to one outer wall of the mounting housing 19, and the housing 24 communicates with the mounting housing 19. Hydraulic oil is stored between the housing 24 and the mounting housing 19. The internal sliding connection consists of two connecting plates 25, with multiple connecting springs 26 bolted between them. Multiple insertion rods 27 are slidably inserted into the outer wall of one side of the connecting plate 25. The insertion rods 27 can be inserted into the pin holes on the pressure knife 21, fixing the pressure knife 21 inside the connecting seat 20. When the pressure knife needs to be replaced, the adjusting bolt 22 can be rotated. The adjusting bolt 22 will then slide the piston plate 23 inside the mounting shell 19, and the piston plate 23 will return to its original position. The hydraulic oil inside the mounting shell 19 and the housing 24 will not be squeezed by the piston plate 23. Then, under the action of the multiple connecting springs 26, the two connecting plates 25 inside the housing 24 will move closer to each other, and the insertion rods 27 will disengage from the connecting seat 20 and no longer restrict the pressure knife 21. Subsequently, the worker can pull the pressure knife 21 to one side to achieve quick replacement of the pressure knife 21, reducing the difficulty of disassembling and replacing the pressure knife 21. One end of the insertion rod 27 is inserted into the connecting seat 20, and the insertion rod 27 is inserted into the pressure knife 21.

[0036] Working principle: When using this device to bend large aluminum plates, first, multiple electric rollers 9 are started, causing the belt 8 to begin circular motion. Then, the large aluminum plate is placed on one side of the top of the housing 5. The belt 8 then carries the aluminum plate down to the lower module 3. When the aluminum plate is blocked by the raised limit plate 12, multiple pressing cylinders 29 are activated, and the pressing block 30 moves inside the fixed seat 28, pressing down on the portion of the aluminum plate inside the fixed seat 28. Then, two hydraulic cylinders 18 are activated, and the mounting shell 19 carries the pressing block installed inside the connecting seat 20. As the cutting tool 21 descends, it presses the portion of the aluminum plate on the lower die 3. Simultaneously, the two lifting cylinders 14 activate, their output ends lifting the fixed seat 28. The fixed seat 28 rotates around the mounting shaft 10 under the operation of the lifting cylinders 14. This causes one side of the aluminum plate held by the lifting assembly 2 to tilt upwards, fulfilling the requirement that one side of the aluminum plate be lifted during bending by the cutting tool 21. After bending is complete, the hydraulic cylinder 18 lifts the mounting shell 19, and the cutting tool 21... It will separate from the lower mold 3, no longer pressing against the bent aluminum plate. At the same time, the output end of the existing lifting cylinder 14 will retract, causing the lifting component 2 to drop the raised aluminum plate downwards. The aluminum plate will fall back onto the belt 8. Subsequently, the lifting cylinder 16 can be operated to start, and the limiting plate 12 will slide inside the slot 32 and the insertion slot 15. The limiting plate 12 will retract into the lower mold 3. Then, under the transport action of the moving belt 8, the aluminum plate with one side folded will flow onto the other belt 8. When the aluminum plate has completely flowed out of the belt 8, the above steps can be repeated to place a new aluminum plate. The aluminum plate is placed on belt 8, and then transported by belt 8 to the position of limit plate 12. Subsequently, the electric roller 9 on the other belt 8 will reverse, and belt 8 will carry the aluminum plate that has been bent once to the limit plate 12. When both aluminum plates are in contact with the limit plate 12 on one side, hydraulic cylinder 18 will repeat the above steps, so that the two pressure knives 21 on the mounting shell 19 will bend at the same time. After bending, the belt 8, limit plate 12 and other structures will repeat the above steps to transport the aluminum plate, which meets the need for continuous bending of multiple aluminum plates.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
