Description

Technical Field

[0001] This utility model discloses a bending device for processing metal shells, which relates to the field of shell bending processing technology. Background Technology

[0002] Shell bending is a common metalworking process used to bend metal materials (usually thin sheets) at predetermined angles or shapes to form the shape of a shell. This process is widely used in the manufacture of electronic device housings, automotive body parts, machinery housings, and household appliance housings. The basic principle of shell bending is to use mechanical force to plastically deform the metal sheet within a specified bending area to achieve the desired bending angle and shape. Typically, the bending occurs in a portion of the sheet metal, while the portion outside the bending area remains straight.

[0003] A known fixed cabinet sheet metal shell bending device can be found in Chinese Utility Model Patent CN222491614U, which discloses a sheet metal shell bending device that "includes a processing table and a conveyor line set on the processing table. The processing table has two supports for supporting sheet metal parts, located on opposite sides of the conveyor line. The processing table is equipped with a drive assembly for controlling the axial movement of the supports, and a limiting assembly for fixing the sheet metal parts is also provided on the supports. A drive component is fixedly installed on one side of the supports, and an extrusion head is provided at the output end of the drive component. Compared with existing technologies, this device can bend the sheet metal parts at different positions as needed, thereby achieving more flexible and diverse processing requirements, saving equipment setup time and labor costs. It can also bend from both sides, reducing manual operation and waiting time, and improving production efficiency."

[0004] In the above-mentioned mechanism, the sheet metal shell is bent by using the cooperation of the pressure block and the extrusion head. However, during this process, the bending angle may crack or become defective due to the large downward pressure. Therefore, it is necessary to provide a bending device for processing metal shells to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bending device for processing metal shells, which achieves the effect of smooth bending at the bending angle, reducing breakage and angle deviation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for processing metal shells, comprising a chassis, a support plate on the chassis for mounting various mechanisms, a conveyor line on the chassis, a positioning mechanism on the chassis, a pressing mechanism on the chassis, and a bending mechanism on the chassis; the positioning mechanism includes a positioning plate and a fixing plate, the positioning plate being fixedly connected to the support plate, and the fixing plate being fixedly connected to the support plate; the pressing mechanism includes pressure blocks, two sets of pressure blocks are provided, and the pressure blocks are driven by cylinders; the bending mechanism includes a moving block, a rotating shaft being rotatably mounted on the moving block, a flat block being rotatably mounted on the rotating shaft, and a transmission rod being rotatably mounted below the moving block.

[0007] Preferably, a connecting block is slidably mounted on the flat block, and a spring is provided at the connection between the connecting block and the flat block.

[0008] Preferably, the pressing mechanism is installed above the positioning mechanism, and the bending mechanism is installed below the pressing mechanism.

[0009] Preferably, the positioning plate is driven by a cylinder, and the transmission rod is driven by a cylinder.

[0010] Preferably, the outer side of the pressure block is provided with a bevel.

[0011] Preferably, there are two sets of pressing mechanisms and two sets of bending mechanisms.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The operator transports the metal shell component to the positioning mechanism via a conveyor line. The positioning mechanism laterally positions the metal shell component, and the pressing mechanism presses down on the metal shell component. In specific operation, after the pressing mechanism and the positioning mechanism fix the metal shell component, the bending mechanism is driven by a cylinder to move the transmission rod upward and offset. The pressure block aligns with the gap between the flat block and the moving block. The flat block is pressed down first, causing a small section of the metal shell component placed on the flat block to bend. That is, a small height difference appears at the connection between the flat block and the moving block. During the pressing and fixing process, the gap between the flat block and the moving block is pressed to create the crease required for subsequent bending. This allows the subsequent rotational bending of the moving block to bend along the crease, ensuring that breakage or excessive deformation of the metal shell component is reduced during bending. Under the pressure of the pressure block, while the flat block remains stationary, the metal shell component begins to bend until it is bent to a suitable angle. This achieves the effect of smooth bending of the bending angle, reducing breakage and angle deviation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples:

[0019] like Figure 1 As shown, a bending device for processing metal shells includes a housing 1, a conveyor line 2 installed on the housing 1, a positioning mechanism 3 installed on the housing 1, a pressing mechanism 4 installed on the housing 1, and a bending mechanism 5 installed on the housing 1.

[0020] The pressing mechanism 4 is installed above the positioning mechanism 3, and the bending mechanism 5 is installed below the pressing mechanism 4;

[0021] Conveyor line 2 is a tracked conveyor device, which is existing technology. Its main function is to transport metal shell components, and it will not be described in detail here.

[0022] In actual operation, the staff transports the metal shell component to the positioning mechanism 3 via the conveyor line 2. The positioning mechanism 3 positions the metal shell component laterally, the pressing mechanism 4 presses down on the metal shell component, and the bending mechanism 5 bends the metal shell component.

[0023] like Figure 2 As shown, the chassis 1 is provided with a support plate 11 for mounting various mechanisms;

[0024] The positioning mechanism 3 includes a positioning plate 32 and a fixing plate 31. The positioning plate 32 is fixedly connected to the support plate 11, and the fixing plate 31 is fixedly connected to the support plate 11. The positioning plate 32 is driven by a cylinder.

[0025] In actual operation, the cylinder drives the positioning plate 32 to move closer to the fixed plate 31, thereby driving the side of the metal housing component to move closer to the fixed plate 31 until the other side touches the surface of the fixed plate 31, thus completing the lateral positioning.

[0026] The pressing mechanism 4 includes a pressing block 41, which is provided in two sets, and the pressing block 41 is driven by a cylinder.

[0027] The main function of the pressing mechanism 4 is to drive the pressing block 41 to move towards the bending mechanism 5 through the cylinder, so as to provide the bending force for the bending motion. At the same time, it can also fix the metal shell component so that it is not easy to move.

[0028] The bending mechanism 5 includes a moving block 51, a rotating shaft 52 rotatably mounted on the moving block 51, a flat block 53 rotatably mounted on the rotating shaft 52, and a transmission rod 54 rotatably mounted below the moving block 51. The transmission rod 54 is driven by a cylinder.

[0029] In actual operation, after the pressing mechanism 4 and the positioning mechanism 3 fix the metal shell component, the cylinder drives the transmission rod 54 to move upward and offset. Because the moving block 51 is rotatably connected to the transmission rod 54, the moving block 51 rotates upward around the rotation axis 52, with a maximum rotation angle of ninety degrees. The pressing block 41 presses against the gap between the flat block 53 and the moving block 51. Under the pressure of the pressing block 41, while the flat block 53 remains fixed, the metal shell component begins to bend until it is bent to the appropriate angle.

[0030] However, due to excessive downward pressure during bending, there is a gap between the flat block 53 and the moving block 51. During bending, there may be breakage or excessive deformation of the metal shell component, resulting in defects. Therefore, a connecting block 531 is slidably installed on the flat block 53, and a spring 532 is provided at the connection between the connecting block 531 and the flat block 53.

[0031] This configuration allows the planar block 53 to be pressed down first when the pressing mechanism 4 presses down, causing a small section of the metal shell component placed on the planar block 53 to be bent. That is, a small height difference appears at the connection between the planar block 53 and the moving block 51. This allows the gap between the planar block 53 and the moving block 51 to be pressed out during the pressing and fixing process, so that the subsequent rotational bending of the moving block 51 can be bent along the crease. This ensures that the breakage or excessive deformation of the metal shell component is reduced during bending. At the same time, the moving block 51 also plays a role in maintaining the bending angle during the bending process.

[0032] The outer side of the pressure block 41 is provided with a slope (not shown in the figure);

[0033] The inclined surface allows the sharp corner of the pressure block 41 to bend well onto the metal shell component after it is pressed against the flat block 53, making bending convenient.

[0034] The pressing mechanism 4 is provided in two sets, and the bending mechanism 5 is provided in two sets;

[0035] The arrangement of two sets of pressing mechanisms 4 and bending mechanisms 5 enables the device to process the same metal shell component from both ends, increasing processing efficiency;

[0036] In summary, the operator, through the conveyor line 2, transports the metal housing component to the positioning mechanism 3. The positioning mechanism 3 laterally positions the metal housing component, and the pressing mechanism 4 presses down on the metal housing component. During operation, after the pressing mechanism 4 and the positioning mechanism 3 have fixed the metal housing component, the bending mechanism 5 is driven by a cylinder to move the transmission rod 54 upwards. The pressure block 41 aligns with the gap between the flat block 53 and the moving block 51, first pressing down on the flat block 53, causing a small section of the metal housing component placed on the flat block 53 to bend slightly. A small height difference appears at the connection between the flat block 53 and the moving block 51, so that during the pressing and fixing process, the gap between the flat block 53 and the moving block 51 is pressed out with the crease required for subsequent bending. This allows the subsequent rotation and bending of the moving block 51 to bend along the crease, ensuring that the bending process reduces breakage or excessive deformation of the metal shell component. Under the pressure of the pressure block 41, the flat block 53 remains stationary while the metal shell component begins to bend until it is bent to the appropriate angle. This achieves the effect of smooth bending of the bending angle, reducing breakage and angle deviation.

All technical solutions within this concept are within the scope of protection of this application.
