Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal bending devices, and in particular relates to a sheet metal bending device that can automatically unload and load materials. Background Technology

[0002] Sheet metal refers to metal sheets such as steel plates, aluminum plates, and copper plates, and also refers to the processing of these metal sheets. Sheet metal is a comprehensive cold processing technology for thin metal sheets.

[0003] Sheet metal bending technology can process metal sheets into the required shapes, such as bending, folding, and rounding corners, thereby realizing the forming of sheet metal parts. This shape change is the basis for manufacturing various complex structural parts. Sheet metal bending equipment is a device used to bend metal sheets. Its basic principle is to use the plastic deformation of metal to manufacture parts or components of the required shape and size. In the process of using existing traditional sheet metal bending equipment, the loading and unloading of sheet metal is often done manually, which is cumbersome and increases the labor force. The problem with the above technology is that traditional sheet metal bending equipment cannot automatically unload and load sheet metal. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a sheet metal bending device that can overcome or at least partially solve the above problems by automatically unloading and loading.

[0005] This utility model is implemented as follows: a sheet metal bending device capable of automatic unloading and loading includes a bending assembly and a support assembly. The bending assembly includes a worktable, a controller, a support frame, an electric hydraulic cylinder, and a bending head. The bottom of the controller is fixedly connected to the left side of the front side of the top of the worktable. The bottom of the support frame is fixedly connected to the top of the worktable. The bottom of the electric hydraulic cylinder is fixedly connected to the top of the support frame. The bottom of the output end of the electric hydraulic cylinder passes through the support frame and is fixed to the top of the bending head by bolts. The support assembly is disposed on the top of the worktable. The support assembly includes two first brackets, two first electric telescopic columns, and two support platforms. The bottoms of the two first brackets are fixedly connected to the left and right sides of the top of the worktable, respectively. The opposite ends of the two first electric telescopic columns are fixedly connected to the opposite sides of the two first brackets, respectively. The opposite ends of the output ends of the two first electric telescopic columns pass through the two first brackets and are fixedly connected to the opposite sides of the two support platforms, respectively. A loading assembly and a pushing assembly are disposed on the front side of the top of the worktable. The pushing assembly is located in front of the loading assembly.

[0008] To enable automatic feeding of sheet metal, preferably, the feeding assembly includes a feeding conveyor belt and a baffle. The bottom left side of the feeding conveyor belt is fixedly connected to the top of the workbench, the bottom of the baffle is fixedly connected to the top left side of the feeding conveyor belt, and the rear left side of the feeding conveyor belt is abutted against the front side of the two support platforms. By placing the sheet metal on the conveyor belt of the feeding conveyor belt, the feeding conveyor belt can transport the sheet metal to the left, and the baffle acts as an interceptor to prevent the sheet metal from moving beyond its designated position.

[0009] In order to push the sheet metal to the top of the two support platforms, preferably, the pushing assembly includes a second bracket, a second electric telescopic column, and a push plate.

The bottoms of multiple limiting blocks are fixedly connected to the top of the worktable. Through multiple sliding rods and multiple limiting blocks, the bearing area of ​​the two support platforms can be increased, the bearing capacity can be improved, and the stability of sheet metal bending can be maintained.

[0011] To prevent the sheet metal portion from extending beyond the top of the two support platforms, preferably, a U-shaped block is fixedly connected to the rear side of the top of the bending head, and a baffle is fixedly connected to the bottom of the U-shaped block. The front side of the baffle is in contact with the rear side of the two support platforms, and the baffle serves a protective function, limiting the range of movement of the sheet metal and restricting the range of movement of the sheet metal to the top of the two support platforms.

[0012] In order to discharge the processed sheet metal, preferably, the workbench has a discharge hole inside, and the bottom of the workbench is fixedly connected to a guide block, which is connected to the discharge hole. After the sheet metal is bent, the operation of the two first electric telescopic columns causes the two support platforms to move in opposite directions, so that the sheet metal can fall down through the discharge hole. The guide block can limit the falling range of the sheet metal.

[0013] In order to automatically transport the falling sheet metal, preferably, two mounting blocks are fixedly connected to the rear side of the workbench, and a discharge conveyor belt is fixedly connected to the bottom of the two mounting blocks.

The bottom of the output end of the electric hydraulic cylinder 104 passes through the support frame 103 and is fixed to the top of the bending head 105 by bolts. The support assembly 2 is disposed on the workbench 101. The top of the workbench 101 includes a support assembly 2 comprising two first brackets 201, two first electric telescopic columns 202, and two support platforms 203. The bottoms of the two first brackets 201 are fixedly connected to the left and right sides of the top of the workbench 101, respectively. The opposite ends of the two first electric telescopic columns 202 are fixedly connected to the opposite sides of the two first brackets 201, respectively. The opposite ends of the output ends of the two first electric telescopic columns 202 pass through the two first brackets 201 and are fixedly connected to the opposite sides of the two support platforms 203, respectively. A feeding assembly 3 and a pushing assembly 4 are provided on the front side of the top of the workbench 101, with the pushing assembly 4 located in front of the feeding assembly 3. The bending assembly 1 is used for bending sheet metal.Support component 2 is used to support sheet metal. To enable automatic feeding of the sheet metal, feeding component 3 includes a feeding conveyor belt 301 and a baffle 302. The bottom left side of the feeding conveyor belt 301 is fixedly connected to the top of the workbench 101, and the bottom of the baffle 302 is fixedly connected to the top left side of the feeding conveyor belt 301. The rear left side of the feeding conveyor belt 301 is abutted against the front side of the two support platforms 203. By placing the sheet metal on the conveyor belt 301, the feeding conveyor belt 301 can transport the sheet metal to the left. The baffle 302 acts as an interceptor to prevent the sheet metal from moving beyond its designated position. To push the sheet metal to the top of the two support platforms 203, pushing component 4 includes a second bracket 401, a second electric telescopic column 402, and a push plate 403. The bottom of the frame 401 is fixedly connected to the front side of the top of the workbench 101. The rear side of the second electric telescopic column 402 is fixedly connected to the front side of the second support 401. The rear side of the output end of the second electric telescopic column 402 passes through the second support 401 and is fixedly connected to the front side of the push plate 403. When the feeding conveyor belt 301 moves the sheet metal to the left, by running the second electric telescopic column 402, the output end of the second electric telescopic column 402 will drive the push plate 403 to move backward, thereby pushing the sheet metal. In order to improve the stability of the two support platforms 203, the front and rear sides of the opposite sides of the two support platforms 203 are fixedly connected to the sliding rods 5. The surfaces of the multiple sliding rods 5 are slidably connected to the limiting blocks 6. The bottoms of the multiple limiting blocks 6 are all connected to the workbench 101. The top of the bending head 105 is fixedly connected to the support platform 203.

To prevent the sheet metal from extending beyond the top of the two support platforms 203, a U-shaped block 7 is fixedly connected to the rear side of the top of the bending head 105. A baffle 8 is fixedly connected to the bottom of the U-shaped block 7. The front side of the baffle 8 fits against the rear side of the two support platforms 203, providing protection and limiting the movement range of the sheet metal, thus restricting its movement to the top of the two support platforms 203. To discharge the processed sheet metal, a discharge hole 9 is provided inside the workbench 101. A guide block 10 is fixedly connected to the bottom of the workbench 101 and communicates with the discharge hole 9. After the sheet metal is bent, the operation of the two first electric telescopic columns 202 causes the two support platforms 203 to move in opposite directions, allowing the sheet metal to fall downwards through the discharge hole 9. The guide block 10 limits the falling range of the sheet metal. To automatically transport the falling sheet metal, two mounting blocks 11 are fixedly connected to the rear side of the workbench 101. The bottom of the two mounting blocks 11 is fixedly connected to the unloading conveyor belt 12. The falling sheet metal will fall to the top of the unloading conveyor belt 12. Through the operation of the unloading conveyor belt 12, the processed sheet metal is transported backwards. The controller 102 can be connected to the electric hydraulic cylinder 104, the first electric telescopic column 202, the second electric telescopic column 402, the loading conveyor belt 301, and the unloading conveyor belt 12 via wiring.

[0025] The working principle of this utility model:

[0026] When sheet metal bending is required, the feeding conveyor belt 301 is operated to transport the sheet metal to the left. The baffle 302 limits the sheet metal movement. When the feeding conveyor belt 301 stops, the output end of the second electric telescopic column 402 will cause the push plate 403 to move backward. The push plate 403 will push the sheet metal backward, pushing it to the top of the two support platforms 203. The sheet metal is prevented from moving beyond its designated position by the baffle 8. Then, the output end of the second electric telescopic column 402 drives... Push plate 403 returns to its original position, and electric hydraulic cylinder 104 is activated, causing the output end of electric hydraulic cylinder 104 to move bending head 105 downward, thereby enabling bending head 105 to bend sheet metal. After processing, the operation of the two first electric telescopic columns 202 will cause the two support platforms 203 to move in opposite directions through the output end. Due to the movement of the two support platforms 203, the sheet metal will fall downward by its own gravity, pass through discharge hole 9 and fall to the top of unloading conveyor belt 12 through guide block 10. The operation of unloading conveyor belt 12 will cause the sheet metal to be transported backward.
