Description

Technical Field

[0002] Sheet metal refers to the processing of thin metal sheets into various shapes of metal products. It is widely used in many industries, such as automobile manufacturing, construction, and electronics. During use, sheet metal needs to be bent to adapt it to different application requirements.

[0003] A search revealed that Chinese patent CN213134584U discloses a sheet metal bending machine, comprising: a load-bearing component including a base, a lower die, a support column, and a load-bearing beam; a receiving groove is formed on one side of the support column, and a sliding groove is formed on the support column, the sliding groove connecting to the receiving groove; a fixed column is also connected to the top of the support column corresponding to the receiving groove; and a bending component including a moving plate, a lifting element, a guide rail, an upper die, a pushing element, a pulley, and a tension spring; one end of the lifting element is connected to the load-bearing beam; the opposite ends of the guide rail are respectively inserted and protrude beyond the sliding groove and connected to the pulley; the pulley and the tension spring are both located in the receiving groove; one end of the tension spring is connected to the guide rail, and the other end is connected to the fixed column. The above sheet metal bending machine has a simple structure and is easy to use. The guide rail is slidably connected to the support column, and the upper die is slidably connected to the guide rail. Through the pushing element and the lifting element, the upper die can be driven to abut against different positions of the lower die, allowing bending of different positions of the workpiece, greatly enhancing practicality and improving processing efficiency. However, the existing technology has the following shortcomings in use:

[0004] The sheet metal bending machine described above has a fixed bending angle for sheet metal parts. Only by changing the mold can it be bent to other angles. This is not only cumbersome to operate, but also undoubtedly increases the workload of the workers. As a result, the bending machine has low overall flexibility and is difficult to meet the processing needs of sheet metal parts with different bending angles.

[0005] Therefore, there is an urgent need for a bending device for sheet metal processing to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a sheet metal bending device that can solve the problem that the sheet metal bending machine used in the above-mentioned applications has a fixed bending angle for sheet metal parts, making it difficult to meet the processing requirements for different bending angles of sheet metal parts.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The application is as follows:

[0009] A sheet metal bending device includes a processing table. A bearing plate is horizontally fixedly installed on the inner surface of the processing table. A guide block is fixedly connected to the top of the bearing plate. A connecting shaft located directly behind the bearing plate is fixedly connected to the inner surface of the processing table. A bending plate is rotatably sleeved on the connecting shaft. V-shaped plates are fixedly connected to both sides of the bending plate. An mounting plate is fixedly connected between the two V-shaped plates. A fixing plate is fixedly installed on the inner surface of the processing table.

A pressure plate is fixedly connected to the push rod end of the second electric push rod.

[0011] As a preferred technical solution of this application, the pressure plate is located directly above the bearing plate, and the front and rear end faces of the pressure plate are both convex arc surfaces.

[0012] As a preferred technical solution of this application, the top of the pressure plate is fixedly connected to two symmetrically distributed guide rods, both of which movably pass through the connecting frame.

[0013] As a preferred technical solution of this application, the mounting plate is inclined, and the second mounting block is fixedly installed on the middle of the inclined lower surface of the mounting plate.

[0027] Example:

[0028] like Figure 1-4As shown, this embodiment proposes a sheet metal bending device, including a processing table 1. A bearing plate 2 is horizontally fixedly installed on the inner surface of the processing table 1. A guide block 3 is fixedly connected to the top of the bearing plate 2. A connecting shaft 4 located directly behind the bearing plate 2 is fixedly connected to the inner surface of the processing table 1. A bending plate 5 is rotatably sleeved on the connecting shaft 4. The left and right end faces of the bending plate 5 are respectively in contact with the two opposite inner surfaces of the processing table 1. The sheet metal part to be processed is placed on the bearing plate 2 and the bending plate 5, so that the left side surface of the sheet metal part is in contact with the outer surface of the guide block 3 to guide the position of the sheet metal part and prevent deviation. V-shaped plates 6 are fixedly connected to both sides of the bending plate 5. A mounting plate 7 is fixedly connected between the two V-shaped plates 6. The mounting plate 7 is inclined. The processing table 1 is equipped with a fixed plate 8 on its inner surface. A first mounting block 9 is fixedly connected to the middle of the upper surface of the fixed plate 8. A connecting ear 10 is hinged to the first mounting block 9. A first electric push rod 11 is fixedly installed on the end face of the connecting ear 10 away from the first mounting block 9. A second mounting block 12 is hinged to the push rod end of the first electric push rod 11. The second mounting block 12 is fixedly installed on the middle of the inclined lower surface of the mounting plate 7. When the first electric push rod 11 is activated, the push rod end of the first electric push rod 11 pushes the second mounting block 12 and the mounting plate 7. Since the mounting plate 7 is fixedly connected to the two V-shaped plates 6, the bending plate 5 can rotate around the connecting shaft 4, so that the bending plate 5 itself is in an inclined state, thereby enabling the bending of the fixed sheet metal parts.

[0029] like Figure 1 and Figure 2 As shown, a connecting frame 13 is fixedly connected to the top of the processing table 1. A second electric push rod 14 is fixedly installed at the center of the upper surface of the connecting frame 13. A pressure plate 15 is fixedly connected to the push rod end of the second electric push rod 14. The pressure plate 15 is located directly above the bearing plate 2. The front and rear ends of the pressure plate 15 are both convex arc surfaces. When the second electric push rod 14 is activated, the pressure plate 15 is moved down by the second electric push rod 14, so that the lower surface of the pressure plate 15 is in contact with the sheet metal part, thereby achieving the pressing and fixing of the sheet metal part and preventing the sheet metal part from shifting during the bending process.

[0030] like Figure 1 and Figure 2 As shown, two symmetrically distributed guide rods 16 are fixedly connected to the top of the pressure plate 15. Both guide rods 16 movably pass through the connecting frame 13. The two guide rods 16 help to ensure the stability of the pressure plate 15 during vertical movement.

[0031] like Figure 1 and Figure 3 As shown, a limiting block 17 is fixedly connected to the inner surface of the processing table 1. When the lower surface of the bending plate 5 is in contact with the upper surface of the limiting block 17, the bending plate 5 is in an initial horizontal state.

[0032] like Figure 1 As shown, a container 18 is installed on the right side surface of the processing table 1. The container 18 makes it convenient for workers to place personal work items such as gloves.

[0033] The working principle of the above embodiment is as follows: The first electric push rod 11 and the second electric push rod 14 are both electrically connected to an external control power supply. The operator first places the sheet metal part to be processed on the bearing plate 2 and the bending plate 5, so that the left side surface of the sheet metal part is in contact with the outer surface of the guide block 3 to guide the position of the sheet metal part. Then, the second electric push rod 14 is activated, which drives the pressure plate 15 to move down, so that the lower surface of the pressure plate 15 is in contact with the sheet metal part, thereby pressing and fixing the sheet metal part. Then, the first electric push rod 11 is activated, which pushes the second mounting block 12 and the mounting plate 7 through the push rod end of the first electric push rod 11. Since the mounting plate 7 is fixedly connected to the two V-shaped plates 6, the bending plate 5 can rotate around the connecting shaft 4, so that the bending plate 5 itself is in an inclined state, thereby enabling the bending of the fixed sheet metal part. This device can bend the sheet metal part into different angles according to the actual processing requirements, with higher overall flexibility and a wider range of applications.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
