Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine that can be quickly adjusted. Background Technology

[0002] A bending machine is a mechanical device used to process metal materials. It is mainly used to bend metal sheets into specific angles or shapes under pressure to produce various mechanical parts and components. Therefore, bending machines are widely used in the manufacturing industry, covering almost every sector, such as automobiles, aerospace, home appliances, construction, and electronics, where they play an important role.

[0003] A bending machine places a sheet metal on a bending seat, and then a hydraulic cylinder pushes the upper die downwards, closing it with the lower die (the bending seat) to generate pressure, thus bending the sheet metal into shape within the bending groove of the bending seat. However, most existing bending seats are fixed and difficult to adjust. Therefore, the bending groove on them is difficult to adjust according to the needs of the sheet metal, especially when the sheet metal is thick, which limits the use of the equipment. Summary of the Invention

[0004] The main objective of this invention is to provide a bending machine that can be quickly adjusted, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-adjustable bending machine includes a fixed base, an adjustment device fixedly installed at the center of the front end of the fixed base, a controller fixedly installed at the left front end of the fixed base, a support device fixedly installed at the front and rear upper ends of the fixed base, an adjustment groove opened in the center of the upper end of the fixed base, a bending machine body fixedly installed at the rear upper end of the fixed base, a first hydraulic cylinder fixedly installed at the front upper end of the bending machine body, and a bending device fixedly installed at the output end of the first hydraulic cylinder.

[0007] Preferably, the adjustment device includes a servo motor, with a forward and reverse screw fixedly mounted at the output end of the servo motor. Two adjusting blocks are threadedly mounted on the outer surface of the forward and reverse screws, and bending seats are fixedly mounted on the upper ends of the two adjusting blocks. Each bending seat has a slot at its opposite end. The forward and reverse screws are rotatably mounted within the adjustment slots, and the servo motor is inserted and fixedly mounted at the center of the front end of the fixed seat. The servo motor drives the forward and reverse screws to rotate within the adjustment slots. At this time, the adjusting blocks on the forward and reverse threads of the forward and reverse screws slide away from each other within the adjustment slots, thereby adjusting the bending groove formed between the two bending seats, thus adapting to different types of metal sheets.

[0008] Preferably, the support device includes two mounting bases. A second hydraulic cylinder is fixedly mounted at one end of each mounting base, and a top plate is fixedly mounted at the output end of each of the two second hydraulic cylinders. The two mounting bases are respectively fixedly mounted at the front and rear of the upper end of a fixed base. By pushing the top plate at the output end of the second hydraulic cylinder, the top plate can be inserted precisely into the slot on the bending seat, thereby supporting and limiting the bending seat and preventing it from sliding under force.

[0009] Preferably, the bending device includes a bending head, with screw holes at both the upper left and upper right sides of the bending head. A mounting plate is fixedly installed at the output end of the first hydraulic cylinder, and mounting screws are installed at both the upper left and upper right sides of the mounting plate. The bending head is fixedly installed on the lower end of the mounting plate by the mounting screws. When the bending head wears out or needs to be replaced with a different shape, the bending head can be disassembled by loosening the mounting screws on the mounting plate.

[0010] Preferably, the bending seat is in the shape of a right trapezoid.

[0011] Preferably, the top plate and the slot are the same size and their positions correspond.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Place the metal sheet on two bending seats. Then, push the mounting plate and bending head downwards using hydraulic cylinder No. 1. The bending head will press the metal sheet into the bending groove between the two bending seats, thus bending the metal sheet into shape. When different types of sheets need to be bent, the servo motor drives the forward and reverse screws to rotate in the adjustment groove. At this time, the adjusting blocks on the forward and reverse threads of the forward and reverse screws slide away from each other in the adjustment groove, thereby adjusting the bending groove formed between the two bending seats, thus making it suitable for different types of metal sheets.

[0014] 2. After the two bending seats are adjusted, the top plate at the output end is pushed by the second hydraulic cylinder so that the top plate can be inserted into the slot on the bending seat, thereby supporting and limiting the bending seat and preventing the bending seat from sliding when under force.

[0015] 3. When the bending head is worn or needs to be replaced with a different shape, the bending head can be disassembled by loosening the mounting screws on the mounting plate. Attached Figure Description

[0024] like Figures 1-4As shown, a quick-adjustable bending machine includes a fixed base 1, an adjusting device 2 fixedly installed at the middle of the front end of the fixed base 1, a controller 7 fixedly installed at the left front end of the fixed base 1, a support device 3 fixedly installed at the front and rear ends of the upper end of the fixed base 1, an adjusting groove 5 opened at the middle of the upper end of the fixed base 1, a bending machine body 6 fixedly installed at the rear end of the upper end of the fixed base 1, a first hydraulic cylinder 8 fixedly installed at the front end of the upper end of the bending machine body 6, and a bending device 4 fixedly installed at the output end of the first hydraulic cylinder 8.

[0025] The adjustment device 2 includes a servo motor 20. A positive and negative screw 21 is fixedly installed at the output end of the servo motor 20. Two adjusting blocks 22 are threadedly installed on the outer surface of the positive and negative screw 21. A bending seat 23 is fixedly installed on the upper end of each of the two adjusting blocks 22. A slot 24 is opened at the opposite end of each of the two bending seats 23. The positive and negative screw 21 is rotatably installed in the adjustment groove 5. The servo motor 20 is inserted and fixedly installed in the middle of the front end of the fixed base 1. The bending seat 23 is in the shape of a right trapezoid. The servo motor 20 drives the positive and negative screw 21 to rotate in the adjustment groove 5. At this time, the adjusting blocks 22 on the positive and negative threads of the positive and negative screw 21 slide away from each other in the adjustment groove 5, thereby adjusting the bending groove formed between the two bending seats 23, thus making it suitable for different types of metal sheets.

[0026] The support device 3 includes two mounting bases 30. A second hydraulic cylinder 31 is fixedly installed at one end of each mounting base 30. A top plate 32 is fixedly installed at the output end of each of the two hydraulic cylinders 31. The two mounting bases 30 are respectively fixedly installed at the front and rear of the upper end of the fixed base 1. The top plate 32 and the slot 24 are the same size and corresponding in position. All electrical equipment in this invention is existing technology. The electrical equipment can operate normally during trial operation. The controller 7 is electrically connected to the electrical equipment in this invention. During use, the controller 7 needs to be connected to an external power source. The second hydraulic cylinder 31 pushes the top plate 32 at its output end, allowing the top plate 32 to be inserted precisely into the slot 24 on the bending seat 23, thereby supporting and limiting the bending seat 23 and preventing it from sliding under force.

[0027] The bending device 4 includes a bending head 40, with screw holes 41 on both the upper left and upper right sides of the bending head 40. A mounting plate 42 is fixedly installed at the output end of the first hydraulic cylinder 8. Mounting screws 43 are installed on both the upper left and upper right sides of the mounting plate 42. The bending head 40 is fixedly installed on the lower end of the mounting plate 42 by the mounting screws 43. When the bending head 40 is worn or needs to be replaced with a different shape, the bending head 40 can be disassembled by loosening the mounting screws 43 on the mounting plate 42.

[0028] It should be noted that this utility model is a quick-adjustable bending machine. The metal sheet is placed on two bending seats 23. At this time, the first hydraulic cylinder 8 pushes the mounting plate 42 and the bending head 40 downwards. The bending head 40 then presses the metal sheet into the bending groove between the two bending seats 23, thereby bending the metal sheet into shape. When bending different types of sheets is required, the servo motor 20 drives the forward and reverse screws 21 to rotate within the adjustment groove 5. At this time, the adjusting blocks 22 on the forward and reverse threads of the forward and reverse screws 21 move accordingly. The two bending seats 23 slide away from each other in the adjustment groove 5, thereby adjusting the bending groove formed between them to suit different types of metal sheets. Then, the top plate 32 at the output end of the second hydraulic cylinder 31 is pushed so that the top plate 32 can be inserted into the slot 24 on the bending seat 23, thereby supporting and limiting the bending seat 23 and preventing it from sliding under force. In addition, when the bending head 40 is worn or needs to be replaced with a different shape, the bending head 40 can be disassembled by loosening the mounting screws 43 on the mounting plate 42.
